DISTRIBUTION AND STATUS OF RARE OR ENVIRONMENTALLY SENSITIVE FISHES IN THE LOWER CAHABA RIVER, ALABAMA1 J. Malcolm Pierson, R. Stephen Krotzer, and Stephanie G. Puleo2 Department of Environmental Affairs Alabama Power Company P.O. Box 2641 Birmingham , AL 35291 ABSTRACT Eighty-four collections were made in the lower Cahaba River drain¬ age, a major tributary of the Alabama River in central Alabama, with seine, gill nets, and electrofishing equipment from May 1981 to June 1986. Over 32,000 specimens were collected representing 20 families and 104 species. Distribution records are presented for 13 rare or environ¬ mentally sensitive fishes that occupy the main channel Cahaba River or a few of its larger tributaries; five of the species have been assigned some form of conservation status. Range extensions were discovered for Notropis sp. cf. voluoellus (undescribed Cahaba shiner), Percina auro- lineata (goldline darter), and Percina sp. cf. copelandi (undescribed channel darter) . Notropis candidus (silverside shiner) is reported from the Cahaba River for the first time. Many Alabama rivers have undergone various degrees of environmental stress; populations of many species have been reduced or eliminated in these systems. While the upper Cahaba River has apparently been impacted by some of these same stresses, it appears that the lower section of the Cahaba River could be serving as a refugium for several vulnerable riverine species. INTRODUCTION The Cahaba River, located within the Mobile Bay Drainage, is a ma¬ jor tributary of the Alabama River in central Alabama. The headwaters of the Cahaba are located northeast of Birmingham in St. Clair County, within the Ridge and Valley physiographic region. The river flows for 307 kilometers in a southwestern and then southern direction through the Fall Line Hills and the Black Belt, respectively, before it joins the Alabama River in Dallas County near Selma. Above the Fall Line, the Cahaba River can be classified as a small to medium stream consisting of long pools interrupted by whitewater shoals of varying lengths. These shoals are made up of bedrock, vertical rock slabs, boulders, cobble, and some gravel and sand. Below the drops of the Fall Line, near Cen- treville, the river deepens and begins to meander. Shoals in this sec¬ tion consist of large gravel bars or islands that constrict the flow of the river, creating gravel and cobble riffles and swift runs. Further downstream the coarse gravel and cobble substrate is replaced by fine 1Manuscript received 14 September 1988; accepted 21 October 1988. 2Address: Route 2, Box 722, Calera, AL 35040 1 Pierson, Krotzer, and Puleo gravel, sand, and silt. In this lower section the current slows, ex¬ posed sand or gravel bars become less frequent, and pools increase in length. The river is noticeably deeper and more entrenched in this section . The first report of fishes from the Gahaba system was based on an 1889 seine sample at Helena by Gilbert (1891). The next was a study of the genus Notropis in Alabama by Howell (1957). Notropis uranoscopus (skygazer shiner) was described from the Cahaba by Suttkus in 1959, and Peraina lentiaula (freckled darter) was described by Richards and Knapp in 1964. The first faunal survey of Cahaba fishes was accomplished in 1963 by May; she reported on 36 collections from the Cahaba drainage. Hackney et al. (1968) studied the life history of Moxostoma carinatum (river redhorse) in the Cahaba River. Suttkus and Ramsey (1967), in their description of Peraina aurolineata, the goldline darter, reported on collections of main channel fishes between Helena and Centreville. Freeman (1974) conducted a survey of fishes in the Little Cahaba system. Seehorn (1976) included collection data from the Cahaba system provided by Boschung and Mettee (1974). Ramsey compiled a list of Cahaba drainage fishes for a U.S. Forest Service Report by Kaufmann and Wise (1978). Ramsey (1978) also compiled a list of unusual fishes and their distribution in the Cahaba. In the same year, Stiles reported on the status of the goldline darter and Notropis sp. cf. volucellus (undescribed Cahaba shiner) in the Cahaba and Little Cahaba rivers. Ramsey et al. (1980) reported on sampling rare fishes in the Cahaba. Howell et al. (1982) and Ramsey (1982) conducted independent surveys in the Cahaba to determine the status, distribution, and habitat requirements of the Cahaba shiner and the goldline darter. Most of the upper Cahaba River, from just above the Fall Line in Bibb County (River Bend) to Trussville in northeastern Jefferson County, has been heavily collected; the lower Cahaba River ichthyofauna, how¬ ever, has not been well documented. This study adds substantially to the existing knowledge of the occurrence, distribution, and abundance of rare or environmentally sensitive fishes in the lower Cahaba River. MATERIAL AND METHODS Eighty-four collections were made in the lower Cahaba drainage with seines, gill nets, backpack electrofisher, and boat-mounted electrofish¬ ing equipment. Collections were made from May 1981 to June 1986 in the main channel and major tributaries from approximately 20 kilometers above the Fall Line to the confluence with the Alabama River, a distance of about 150 river kilometers (Figure 1). This is a remote section of the Cahaba River; collection sites suitable for seining were usually not accessible by state highway or county road crossings. Canoes or small johnboats were often used on day trips or overnight floats in an attempt to access and sample all habitat types. RESULTS Over 32,000 fishes were collected representing 20 families and 104 species. Several of the riverine species collected have been assigned 2 Environmentally Sensitive Fishes in the Lower Cahaba River Figure 1. Sample stations from the lower Cahaba River system, Alabama. some form of conservation status. The Cahaba shiner, the goldline dar¬ ter, Scaphirhynehus sp. cf. platorynahus (undescribed Alabama shovelnose sturgeon), Noturus munitus (frecklebelly madtom) , and the freckled dar¬ ter are currently under status review by the United States Fish and Wildlife Service Office of Endangered Species. The State of Alabama 3 Pierson, Krotzer, and Puleo lists the Alabama shovelnose sturgeon and the frecklebelly madtom as endangered and Ammocrypta asprella (crystal darter) and the freckled darter as threatened (Ramsey 1976). The American Fisheries Society Endangered Species Committee lists the Alabama shovelnose sturgeon and the Cahaba shiner as endangered; the frecklebelly madtom, goldline darter, and freckled darter are listed as threatened and the crystal darter as of special concern (Deacon et al.. 1979). In a recent publica¬ tion (Mount 1986), the Cahaba shiner was considered endangered, the goldline darter threatened, and the frecklebelly madtom and crystal darter of special concern; the Alabama shovelnose sturgeon was listed as status poorly known. One Alabama shovelnose sturgeon was sighted while boat electrofish¬ ing in the lower reach of the Cahaba River (station 5) . An additional confirmed specimen was caught by trotline fishermen at station 7. A status survey report by Burke and Ramsey (1985) documents seven occur¬ rences of this sturgeon in the Cahaba River since 1969; the authors indicated that the shovelnose sturgeon has occurred in much reduced numbers since the closing of Miller's Ferry Dam on the Alabama River in 1969. Sixty specimens of Noturus munitus were collected from 11 main channel sites in a 57 km section of the Cahaba (stations 23, 29, 32, 33, 34, 35, 36, 40, 41, 42, and 45). This madtom was usually collected in low numbers over stable gravel or sand/gravel riffles. Seventy speci¬ mens of Ammocrypta asprella were collected from 9 main channel locations in a 79 km stretch of the Cahaba (stations 5, 7, 19, 24, 26, 29, 34, 36, and 41). Crystal darters were usually collected at night over stable gravel in moderate to fast current. At the lower collection sites, crystal darters were occasional to common over sand or a sand/gravel combination. Eight specimens of Percina lenticula were collected from four widely separated sites (stations 20, 31, 48, and 54). Two sites were above the Fall Line in the lower reaches of major tributaries, and two sites were well below the Fall Line in the main channel of the river. The freckled darter was always collected in heavy cover such as Justicia beds, treetops, or logs in moderate to fast current. Range extensions are noted for four species. Eleven specimens of Notropis candidus (silverside shiner) were collected at three locations in the main channel of the Cahaba River as far as 40 km upstream from its confluence with the Alabama River (stations 3, 4, and 24). This is the first report of N. candidus from the Cahaba. This Mobile Basin endemic was collected in slow to moderate current over a substrate of sand with scattered patches of silt and leaf litter. Fifty-six speci¬ mens of the undescribed Cahaba shiner were collected at seven locations (stations 32, 36, 40, 42, 45, 50, and 51); four of these sites were well below the Fall Line. These records extend the known range of the Cahaba shiner 37 km downstream of the Fall Line. Cahaba shiners were most of¬ ten collected over a sand substrate in slow current, but specimens were occasionally taken in shallow gravel riffles. Fifteen specimens of Per¬ cina aurolineata were collected from seven stations in a 14 km section of the main channel of the Cahaba River above the Fall Line and in the lower 12 km of the Little Cahaba River (stations 45, 46, 48, 49, 51, 54, and 55) . One individual was collected from Schultz Creek 3 km upstream from its confluence with the Cahaba (station 48). The goldline darter 4 Environmentally Sensitive Fishes in the Lower Cahaba River was previously thought to be restricted to the main channel of the Caha¬ ba and Little Cahaba rivers . Adults and juveniles were usually found in moderate to fast current over small boulders , cobble, or coarse gravel, but were also observed in patches of Justiaia in moderate current. Sev¬ en specimens of Pereina sp, cf. copelandi (undescribed channel darter) were collected at seven locations (stations 33 , 34, 36 , 45, 47 , 49 , and 58) . These collections extend the range of this undescribed form 28 km downstream onto the Coastal Plain. This darter was collected over sand or fine gravel in moderate current. Several other riverine forms that were collected are being impacted over much of their historical range. Suttkus and Clemmer (1968) report¬ ed Notropis edwardraneyi (fluvial shiner) from the main channel of the river upstream as far as 14 km above the Fall Line and from the lower section of Oakmulgee Creek. During the present study, N. edwardraneyi was collected only at stations 3, 4, 5, and 19. This represents a con¬ siderable reduction of its former range in the Cahaba drainage. Notrop¬ is uranoscopus was commonly collected in the main channel of the Cahaba River (33 of 36 stations) , and it occurred in low numbers in several large tributaries (stations 8, 52, 54, and 55). Moxo stoma earinatum was collected from seven stations in the main channel of the Cahaba, from its confluence with the Alabama River upstream to the first Fall Line shoals (stations 1, 5, 24, 26, 34, 36, and 45); one adult was collected in Schultz Creek, a medium-sized tributary, 3 km upstream from its con¬ fluence with the Cahaba (station 48) . Etheostoma histrio (harlequin darter) was collected at two main channel sites, one above and one below the Fall Line (stations 36 and 45); this species is mentioned because the Cahaba River is near the eastern limit of its range. Pereina vigil (saddleback darter) occupies approximately the same range and habitat in the Cahaba as Noturus munitus . The saddleback darter was collected at 13 locations in stable cobble or gravel runs and riffles (stations 24, 26, 29, 32, 33, 34, 35, 36, 41, 42, 45, 46, and 51). Fishes that were documented prior to this study in the lower Cahaba River but were not collected in the present study include: Acipenser oxyrhynchus (Atlantic sturgeon), Alosa alabamae (Alabama shad), Hybo- gnatkus nuahalis (Mississippi silvery minnow) , Notropis oaeruleus (blue shiner), Cycleptus elongatus (blue sucker), Fundulus stellifer (southern studf ish) , and Mugil aephalus (striped mullet). Acipenser oxyrhynchus was last documented from the Cahaba River at Centreville in Bibb County in 1941 by newspaper accounts and photographs. Alosa alabamae, Hybo- gnathus nuahalis t Fundulus stellifer 3 and Mugil aephalus were last col¬ lected from the Cahaba in 1969. Notropis oaeruleus was last collected in the Cahaba by Suttkus in 1971. Miller’s Ferry Dam, on the Alabama River near Camden, was closed in 1969, creating Dannelly Reservoir. This impoundment affects flows in the lower 20 km of the Cahaba River, creating a lentic habitat with mud and silt substrate. The dam presents a physical barrier to upstream movement from the Alabama River Into the Cahaba, which could explain the absence of the Atlantic sturgeon, Alabama shad , and striped mullet. In¬ creased siltation and organic enrichment from upstream development in Jefferson and Shelby counties could account for the apparent extirpation 5 Pierson, Krotzer, and Puleo of the blue shiner from the Cahaba River. The Mississippi silvery min¬ now possibly depended on a free-flowing Alabama River for some portion of its life history. This hypothesis was first presented by Etnier et al. (1979) with regard to the disappearance of the Mississippi silvery minnow from the Tennessee River system since the early 1940's. Cyclep- tus elongatus was taken from the Cahaba River by Burke and Ramsey (1985) during their Alabama shovelnose sturgeon survey. In summary, the Cahaba system has been stressed by a variety of upstream disturbances that have apparently contributed to the reduction and/or absence of several forms that historically occurred here. Other obligate riverine species have, however, maintained stable populations in the lower section of the main channel of the Cahaba River, which continues to support a diverse and unique assemblage of Mobile Basin freshwater fishes.

INTRODUCTION Spiroplasmas are helical, motile, wall-less prokaryotes in the fam¬ ily Spiroplasmataceae of the class Mollicutes (13, 16). Some spiroplas¬ mas are pathogens of plants (1, 7, 19), others are lethal to honeybees (2), and one isolated from ticks is lethal to chick embryos and causes cataracts and death in suckling rats (14). Recently, spiroplasmas have been isolated from surfaces of flowers of several plants in the United States and southern Europe (3, 5, 9, 10, 15, 18), and evidence suggests that these spiroplasmas may be deposited on flowers by insects (4) . In this paper, we report the isolation of Spiroplasma floricola from flowers collected in Alabama. A preliminary report, the first of an isolation of spiroplasmas in this state (12), has been published. MATERIALS AND METHODS Flowers were collected during May and June from plum trees ( Prunus angustifolia Marsh.) in Autauga County and from peach (P. persica (L.) Batsch.) and Japanese magnolia ( Magnolia soulangeana Soul.) trees on the campus of Auburn University in Lee County. Spiroplasmas were isolated from floral surfaces according to the procedures outlined by Davis et al. (6). Growth of the organisms was indicated by a change from red to yellow of the phenol red indicator in the DMS4 isolation medium (6) , and Manuscript received 10 June 1988; accepted 29 August 1988. 11 Stevens, Cody, Gudauskas, and Patterson confirmed by darkfield microscopy. Uninoculated medium was used as a control in all isolations. T Isolated spiroplasmas were compared with 5. floricola strain 23-6 for substrate (arginine, urea, and sugars) utilization in D187C medium, reversion to bacterial forms, cellular and colonial morphology, and temperature requirements for growth (6) . Serological relationships of the isolated spiroplasmas to groups I-VIII spiroplasmas were determined by R. F. Whitcomb, USDA, AR, Beltsville, MD 20705, using the deforma¬ tion test (20) . RESULTS AND DISCUSSION Spiroplasmas isolated from flowers of plum, peach, and magnolia were triply filter-cloned on DMS4 medium containing agar, and the resul¬ tant cultures were filtered through a 0.45 ym pore size filter and designated as DPRCL3 (plum) , PEA60 (peach) , and AUCL3 (magnolia) . All three isolates were readily subcultured in DMS4 medium, producing an acid reaction (yellow color) in the medium in 18-20 hr. On DMS4 medium with 1% agar, colonies of all the isolates were spreading and diffuse, resembling those of S. floricola (5) but larger than those of S. citri (7). On medium with 2% agar, the three isolates produced colonies that were distinct with granular centers surrounded by small surface satel¬ lite colonies. No reversion to bacterial forms occurred in the three isolates after five passages on penicillin-free medium, nor did any of them grow on agar medium without serum. Broth cultures of all three isolates developed marked turbidity and produced large numbers of helical, motile cells after several passages; generation time for the three isolates was 1.9 hr. The three isolates grew at temperatures ranging from 25 to 37°C, with maximal growth occurring at 34°C. No growth occurred at 40°C, as has been observed with most floral spiroplasmas (5, 9, 10, 15). All three isolates utilized all sugars tested except galactose, and none utilized urea (Table 1). The utilization of trehalose, which is the principal sugar in most insects (11), supports the possibility that the isolates were deposited on the flowers by insects. The isolates closely resembled S. floricola strain 23-6 in substrate utilization. The three isolates were typed serologically by the deformation test against representative strains of groups and subgroups recognized by Junca et al. (8) and in the revised classification of Whitcomb et al. (17). The isolates did not react with any representatives of groups I-VIII, except group III (S’, floricola strain OBMG) (R. F. Whitcomb, personal communication) . Based on these results, isolates DPRCL3, PEA60, and AUCL3 were identified as S. floricola. The three isolates have been deposited in the American Type Culture Collection (ATCC) as ATCC 35006 (AUCL3) , ATCC 35007 (DPRCL3) , and ATCC 35008 (PEA60) .

Stallings Department of Agricultural Economics and Rural Sociology Auburn University , AL 36849-5406 INTRODUCTION History of Alabama's Grain Marketing System Over the last 20 years or more the grain marketing system of Ala¬ bama has changed from mostly family-owned country elevators and feed mills to collection stations and feed manufacturers for large vertically integrated poultry and other operations (4,5,6). Two large soybean pro¬ cessing plants in the northern part of the State provide the protein ingredient for poultry operations. These two soybean processors recent¬ ly have processed more soybeans than are currently produced in Alabama, necessitating importing soybeans into the State. In addition, a corn processing plant was established in Decatur in 1976, necessitating im¬ porting more corn than would have been the case for only grain-consuming animals and a few other minor uses for corn. A comparison of numbers of grain-handling firms in Alabama, by type, in 1970, 1977, and 1985 is given in Table 1 . Note that the biggest changes have been an increase in country elevators, especially from 1970 to 1977, and a decrease in feed mills or processors over the whole period. The country elevator increase was due partly from new river elevators constructed by the State of Alabama and by an increase in satellite elevators to collect grain from large vertically integrated firms. The decrease in feed mills and processors was due mainly to the going out of business of small family feed mills. Even without the corn processing plant, Alabama has been a deficit state for most grains for many years, especially with the advent of the poultry industry which uses large amounts of feed grains. Research on production and utilization of different grains has indicated that Ala¬ bama has averaged producing about 30 percent of the feed grains, mostly corn, needed in recent years (3). Most of the imported feed grains came from Illinois and Indiana, with lesser amounts from other areas. The Public Grain Elevator in Mobile, owned by the State of Alabama, has played a part in the Alabama grain marketing system during this time also. However, even though providing an additional market for Alabama grains, it has mostly exported grain coming in from outside Alabama. Alabama grains exported through Mobile mostly come from the southern half of the State, necessitating replacing it, and more, with imported grains for local processing and other uses from out-of-state. The northern half of Alabama typically exports little grain through Mobile and requires large imports of feed grains and soybeans to supply its poultry industry and the soybean and corn processing plants which are ^Manuscript received 5 July 1988; accepted 20 October 1988. 16 ^ Stallings Table 1, Number of Grain-Handling Firms in Alabama by Type of Firm and Selected Years Type of Firm 1970a b 1977 198.

So far, the newly completed Tennessee-Tombigbee Waterway has played little part in the grain market¬ ing system of Alabama or in the volume of grain business through the Port of Mobile. Procedure The nature of Alabama’s grain marketing system in the 1980 ' s was mostly determined from responses to a two-page questionnaire mailed to grain firms in Alabama as required by a regional project in which Ala¬ bama participated. This questionnaire covered the calendar year 1985 and included such information as the type of firm, some measures of firm size, grains received by mode of transportation and origin, and other information . Three criteria were used in selecting the sample: storage capaci¬ ty, total grains handled, and tons of feed produced. A current directo¬ ry of grain-handling firms, in which these three characteristics are kept up-to-date, provided a basis for choosing a sample. Firms were first arrayed from largest to smallest based on those criteria, and cumulative percentages were computed for each. Firms representing 50 percent of each criteria were chosen as a mandatory 100 percent sample, which included 17 of the 180 firms In Alabama that handled grain (cer¬ tain other firms such as brokers and home offices were not included) . This indicated a concentration of 50 percent of the grain handling activity in less than 10 percent of the firms. Information from these 17 firms was considered absolutely essential and was obtained by several 17 Alabama's Grain Marketing System means including mailed questionnaires, phone contacts, and personal contacts. Some data were estimated from previous surveys and other grain industry contacts when answers to certain questions were not given. All other firms were mailed questionnaires, with the remainder of the sample consisting of whatever number was returned. The multi¬ plier (expansion factor to estimate State totals) for the 17 large firms representing over 50 percent of the activity. was 1 (100 percent) while the multiplier for the remainder of firms was 4 (25% of the remaining firms were returned). Table 2 indicates the total number of firms included in the sample by type of firm. Table 2. Number of Grain Handling Firms in Alabama and Sample by Types, 1985 Type of Firm Est. No. In Ala.

Except for soybeans during the later 1970 's and early 1980' s, and grain sorghum in recent years, Alabama has been in the past, is now, and will probably continue to be a deficit state in almost all the grains used within the State (3). Ex¬ cept for describing trends, no attempt will be made in this paper to explore the reasons for this continued deficit situation. Table 3 pre¬ sents some detail of Alabama's 1985 deficit situation for five major grains . Com Note that for 1985, domestic production of 24.4 million bushels of corn in Alabama represented only 27.0 percent of domestic use for feed manufacturing and use, seed use, and processing. This is very close to the 29-30 percent average over a recent 20 years period reported in 18 Stallings Table 3.

While feed for the poultry industry accounts for a large part of domestic use, a corn processing plant in Decatur in recent years has also taken an increasing amount (13.6 million bushels or 14.1% in 1985) of corn, causing the deficit to be larger than it would be for livestock and poultry use alone. Shipment of Alabama produced corn to ports for foreign export amounted to only 3.1 million bushels (3.2%) of the total 96.7 million bushel disappearance in 1985 and some of this represents trans-shipments of out-of-state corn which is difficult to identify. Also, shipments to out-of-state points from Alabama was only 3.3 million bushels (3.4%) of total disappearance and this is more than offset by similar amounts coming in from these same states . Wheat While wheat production in Alabama in 1985 was down from its peak of 15.2 million bushels in 1983, it still represented a large increase from the 1 to 2 million bushel annual production figures of the 1960 's and 1970 ' s . This is soft red winter wheat, which is often used as a feed ingredient. In spite of increased production in recent years, produc¬ tion in 1985 still represented only 76 percent of domestic use, with over 8 million bushels imported from out-of-state. 19 Alabama's Grain Marketing System Soybeans Like wheat production in Alabama, soybean production was down in 1985 to 27.8 million bushels from its peak year of 53.75 million bushels in 1979. Production has dropped even further since the 1985 survey year to 14.5 and 11.5 million bushels in 1986 and 1987 (estimated), respec¬ tively (2). The major use of soybeans is for crushing into meal (a feed ingredient) and oil. In 1985, almost 41 million bushels were crushed, a quantity greater than the State's total production (Table 3). The meal is used in an expanding poultry industry, especially broilers, thus, the deficit is likely to continue and expand. Shipments of soybeans to ports for export in 1985 were 10.2 million bushels or 17.9% of the estimated disappearance of 56.8 million bushels in 1985. However, these mostly came from south Alabama and, as with corn, some of these could represent trans-shipments which came from out-of-state . As with wheat, grain sorghum production has increased dramatically in the last 20 years from 0.3 million bushels in 1965 to 12.6 million in 1985. Unlike other grains, however, domestic use has virtually equaled production, with most of it utilized locally in Alabama as a substitute for corn in feed manufacturing. Oats Oats are primarily required as an ingredient in certain kinds of feed manufacturing, especially horse feed, and have not been an impor¬ tant crop produced in Alabama. While 1.4 million bushels were produced in Alabama in 1985 and 1.9 million imported from out-of-state, much of the domestic production was used locally while that used by feed manu¬ facturers was mainly imported from out-of-state. Alabama is a deficit state in oats and will probably continue to be. ORIGIN-DESTINATION PATTERNS Because the Southeast, including Alabama, is generally a deficit area in most grains, especially feed grains, there has always been a concern with the origin of needed imports of the different grains. Most previous surveys in Alabama have attempted to identify the origins of each grain by state and mode of transportation. Some studies have even tried to detail out-of-state receipts by month and by sub-regions of specific Corn Belt states. The 1985 two-page survey, on which the data in this article are based, was relatively simple, involving mostly ori¬ gin by states and mode of transportation. However, it was also possible to provide receipts by type of firm within Alabama for different states of origin and destination and by mode of transportation. General Origins Because of the unique relationship between the Southeastern deficit states and the surplus "Corn Belt" states, the several five-year region¬ al projects previous to this one usually included two or three of the 20 Table 4.

The end of the juvenile phase is marked by attainment of sexual maturity, somewhere betwen 254 and 305 mm (Becker, 1983). Juvenile skipjack herring are not as elongate as larvae and appear more adultlike with the characteristic projecting lower jaw and scutes visible (Fig. 2d). Morphometries for specimens 32.0-76.0 mm are pre¬ sented in Table 1. At 32.0 mm, 19 prepelvic and 14 postpelvic scutes were visible; the adult complement of 19 and 16 was fully present at 42.0 mm. Pigmentation on specimens between 32.0 and 42.0 mm was similar to late larval pigmentation except that ventral pigment between the anal and caudal fins became a scattered double row with up to eight melano- phores along the base of the anal fin. By 76.0 mm, pigment was present on the tip of snout, below and immediately posterior to the eye, and on the operculum; pigmentation was scattered above the midline, becoming more dense dorsally; and both dorsal and caudal fins had pigment scat¬ tered along their base and outlining rays. ECOLOGY OF YOUNG The yolk-sac larva pictured in Hogue et al. (1976) and those de¬ scribed in this paper from Wheeler Reservoir are the only documented records of this life phase known to the authors. Unfortunately, exact spatial and temporal collection data for these specimens is not avail¬ able. Pestrak (1977) reported collection of probable yolk-sac larval skipjack herring from the lower Coosa River, Alabama, in early May. TVA biologists collected post yolk-sac larvae in mainstream reser¬ voirs from late April through most of August, with peak densities usual¬ ly occurring in late May or early June. Most collections were from surface waters in littoral habitats (Table 2), usually at night. Mundy (1973) reported similar occurrences in collections from Wheeler Reser¬ voir, Alabama. Walker (1975) collected post yolk-sac larvae from mid¬ channel surface waters at night in late June in Nickajack Reservoir, Tennessee. Simon (1986) reported skipjack herring larvae in Ohio River ichthyoplankton samples during June, with peak densities June 25; most (74 percent) were collected in surface waters. Juvenile skipjack herring were more abundant in mainstream ichthyo¬ plankton samples than in cove rotenone samples collected by TVA. The juveniles in ichthyoplankton samples from Wheeler Reservoir were widely distributed horizontally and vertically (Table 2) , and occurred more often in pelagic open water areas than larvae. ACKNOWLEDGEMENTS The authors are grateful to Dr. David Etnier for loan of larval and juvenile skipjack herring used for morphometric and meristic analysis. 45 Wallus and Kay Table 2.

Fall 1988. Pp. 32-45. Readers of the Journal may be interested in knowing more about Alabama Heritage, a fairly new quarterly publication of the University of Alabama. The Fall 1988 issue is its tenth number. Its articles. Remembering Tallulah , Alabama at Gettysburg y and Charles Mohr, Botanist, suggest the broad range of the magazine's coverage, and this is substantiated by features in previous issues, listed in the index to issues 1-10. The layout and presentation of the magazine are thoroughly professional and most attractive, with photographs and illustrations on nearly every page, many in color. If you are unfamiliar with Alabama Heritage , it certainly deserves a careful looking over the next time you visit your library. Subscription is $12 per year (4 issues) plus 4% sales tax in Alabama, from Alabama Heritage , University of Alabama, Tuscaloosa, AL 35487-0342. Charles Mohr was born in Germany in 1824 and was educated there principally as a chemist. Following graduation, the adventurous young man accompanied a botanist-acquaintance on an expedition to Dutch Guiana (present-day Surinam) , worked for a time as a chemist in Austria, made his way to Britain, and subsequently emigrated to the United States, arriving in New York in 1848 at age 23. The following year he set out by wagon trek for the gold fields of California, and after perils and adventures there and on his return journey via Panama sufficient for several lifetimes, a brief try at farming in Indiana, and travels in Louisiana and Mexico, he settled in Mobile in 1857. He established himself there in a pharmaceutical supply business and prospered during the following years until his death in 1901. Thus it was as a hobby only, and during the later years of his life, that Mohr undertook the botanical exploration, collection, study, and publication that established him as an authority of international stature on the southern forest flora, and specifically the plants of Alabama. In his fine article Dr. Davenport chronicles this monumental body of work, leading eventually to Mohr's publication of Plant Life of Alabama in 1901, but in the telling there shines through much of the character and personality of Charles Mohr, a scientist of distinction surely, but also a delightful and admirable human being whom one would like very much to know and enjoy. Dr. Davenport, I feel, has given me a warm, personal introduction to one of his best friends, and I am grateful for that. His article is highly recommended to anyone interested in Alabama's natural history.

The gopher tortoise has declined prodigiously in recent years to the point that all populations west of the Tombigbee and Mobile Rivers are considered endangered. This decline is attributed to habitat alteration, loss of habitat, and predation by fire ants ( Soleonopsis sp.), armadillos ( Dasypus novemcincCus ) , and humans ( Homo sapiens ) , particularly on eggs and juveniles (see abstract Vol. 60, No. 3, July, 1989). Gopher tortoise hatchlings are rarely found in the wild; this particular hatchling was one of ten found in DeSoto National Park, Mississippi. Gopher tortoises are an important aspect of the sandhills of Southeastern US because of their '•.habit; *of digging large burrows. These burrows are often used by threatened or special concern species such as the eastern indigo snake ( Drymarchon corais) , the Florida pine snake ( PiCuophis melanoleucus ) , the gopher frog ( Rana areolata) , and the Florida mouse ( Podomys floridanus).

Gardner Award was established by the Alabama Academy of Science to honor individuals whose work during residence in Alabama has been outstanding. Persons nominated for this award have included researchers, teachers, industrialists, clinicians and scholars. This report reviews the many contributions and ongoing work of the first five recipients of the Gardner Award 1984-1988. These scientists are Dr. Robert P. Bauman, Professor of Physics, University of Alabama at Bir¬ mingham (1984); Dr. Nolan E. Richards, Research Scientist and Manager of Manufacturing Technology Laboratory, Reynolds Metals Company, Sheffield (1985); Dr. S. T. Wu, Professor of Mechanical Engineering and Director, Center for Space Plasma and Aeronautic Research, University of Alabama in Huntsville (1986); Dr. Herbert H. Winkler, Professor of Microbiology and Immunology, University of South Alabama College of Medicine (1987); and Dr. Richard W. Compans, Professor of Microbiology and Senior Scien¬ tist, Cancer Center, Diabetes Center, and Arthritis Center, University of Alabama at Birmingham (1988). Dr. Wright A. Gardner was the principal founder and first President of the Alabama Academy of Science. Born in 1878 on a farm in the Tyrone Community, Michigan, he entered Albion College, Albion, Michigan plan¬ ning to enter the Methodist ministry, but his interests in plants led him to complete his studies in botany. He came to Alabama in 1917 as Professor of Botany and Plant Physiology at then Alabama Polytechnic Institute (Auburn University) . From his graduate studies at the Univer¬ sities of Michigan and Chicago he realized the intellectual stimulation which could result from meetings of scientists to discuss mutual teach¬ ing and research interests. By the early 1920 's, Gardner was carrying on extensive correspondence about organizing a state scientific society: With the encouragement of the Alabama Education Association (AEA) lead¬ ership he organized a meeting as the Science Section at the April 1924 annual AEA meeting in Montgomery. The program of 26 papers was attended by some 30-40 persons. Dr. Gardner's scientific training and research interests included: (1) the effect of light on the gemination of light-sensitive seeds, (2) decomposition of organic toxins by soil organisms, (3) the decomposition of chlorophyll, (4) an enzyme in the rinds of oranges, and (5) black resistance in sweet potatoes. Dr. and Mrs. Gardner (Mabel Anna Anderson) were parents of four children, Hannon Austin, Louis Wright , Mabel Grace, and Donald Anderson, Manuscript received 28 September 1988, accepted 31 October 1988. 49 Buckner each of whom rose to distinguished positions in their chosen field of endeavor.

AIR FLOW DISTRIBUTION IN AN UNDERFEED RESIDENTIAL STOKER COMBUSTOR USING BITUMINOUS COALS1 N. L. Mukherjee Department of Chemical Engineering Tuskegee University Tuskegee , AL 36088 and 0. J. Hahn Department of Mechanical Engineering University of Kentucky Lexington , KY 40506 ABSTRACT Bituminous coals used in residential space and water stoker heaters emit significant amounts of carcinogenic polycyclic aromatic hydrocar¬ bons, and non-uniform air flow distribution in the retort and in the coal bed causes incomplete combustion of polycyclic aromatic hydrocar¬ bons produced during coal pyrolysis. Investigations were carried out in a Will-Burt automatic underfeed residential stoker combustor to deter¬ mine air flow distribution from the tuyeres to the retort and the coal bed. Air flow from the inside, bottom tuyeres was higher than that from the outside tuyeres, and was lowest at the coal bed center. INTRODUCTION The cost of natural petroleum oil and gas in the United States of America is increasing and deposits are dwindling. It is quite possible in the near future that bituminous coal, which is plentiful as well as readily available, will be a potential fuel source for the residential stoker combustor. Bituminous coal in the state of Alabama has low percentages of sulfur and ash; moreover, in 1982, Alabama was ranked eleventh in coal production among coal-producing states in the United States. Table 1 (Tolson et al. 1982) shows the typical ranges in Alabama bituminous steam coal quality on as as-received basis. Alabama steam coal, because of its good quality and enormous reserves, has an excellent potential market for residential combustors. Bituminous coal, due to coking characteristics, agglomerates and causes blowhole, gas channels in the coal bed; in addition, coal crushes partly and fines segregate in the coal bed during screwfeeding. As a result, air flow distribution is irregular and bed temperature is non- uniform, conditions which inhibit complete combustion of volatile matter and polycyclic aromatic hydrocarbons (PAH) . Manuscript received 19 August 1988; accepted 16 November 1988. 56 Mukherjee and Hahn Table 1. Analysis of Alabama Steam Coal as Received Basis. Moisture, (%) 7-13 (max) Ash, (%) 13-15 (max) MJ/kg 26.62 (max) Sulfur, (%) 0.6-3. ,3 (max) Fixed carbon, (%) 45-65 Volatile matter, (%) 20-27 Ash softening temperature, (°C) 1,065 (min) Ash fusion temperature, (°C) 1,315 (min) With minor modifications in tuyere design, PAH emissions can be significantly reduced. Effective air velocity and uniform air flow distribution in the retort and coal bed can be improved if rows have the proper number of tuyeres and are of the correct size and position. Due to ash softening, agglomerates, clinkers, and segregated coal fines increase air flow resistance; restricting the area of the tuyeres' air outlet will create a higher fan capacity but will also increase cost. Restricting the air outlet area, however, is advantageous in that it tends to equalize air flow to the different portions of the retort. Investigations were carried out at Pittsburgh Energy Technology Center, Department of Energy, in a Will-Burt type underfeed stroker residential combustor; bituminous coal was used in order to achieve an overview of the air flow distribution in the retort and in the coal bed so that investigators could determine how to. modify tuyere design. EXPERIMENTAL PROCEDURE The Will-Burt type residential underfeed stoker combustor (Figure 1) in which investigations were conducted had a capacity of 153 mj/hr, a warm air furnace, a stoker, warm air controls, and a barometric damper. Air from the windbox flowed into the retort through rows of tuyeres. Three tuyere rows were located outside, inside top, and inside bottom of the retort wall. Each row consisted of sixteen tuyeres of the same size with the following dimensions: 7.94 x 10 3m diameter — _outside; (2.06 x 10 2m) x (8.73 x 10 3m) — inside top; and (1.75 x 10 2m) x (1.03 x 10 2m) — inside bottom. Coal rose vertically in the retort through the stoker system. Volatile matter from the coal mixed with air and ignited as it passed through the incandescent layer of the bed and thus effecti¬ vely controlled smoke emission. The investigation determined air flow distribution at variable conditions through the front and rear tuyeres. A pitot tube connected to a differential manometer measured the velocity head. 57 Air Flow Distribution in an Underfeed Residential Stoker TURN DAMPER ■SLIDE IN FIRE DOOR hr— BAROMETRIC DAMPER FEED SCREW WINO DUCT .-LIVE FUEL BED ^IGNITION LINE -LOOSE ASH -CLINKER -REFRACTORY HEARTH -TUYERES -WINO BOX -RETORT —GREEN FUEL Figure 1. Schematic diagram of Will-Burt type residential stoker combustor. Air flow rates were calculated from the following equations: 1 velocity, m/sec = 20.71 (P ) 2 (1) where P = velocity pressure meter of waterflow, m3/sec in tuyere = tuyere surface, m2 x velocity, m/sec (2) To measure the air flow rate and distribution through the tuyeres in the retort, the first test [Figure 2] was conducted without a coal bed. Flow was measured at four different points in each tuyere row and for three different air flow rates. Table 2 shows average flow distri¬ bution through three tuyere rows. The second test [Figure 3] was performed to determine air flow distribution on the coal bed surface at variable air flow and coal feed rates. As is illustrated in Table 3, the air flow was measured on the basis of the height of the water column in the pitot tube; it was measured at three different sections and in the center of the bed, and was calculated at four different points in each section. To determine the degree of fines produced in screwf eedings , as well as their distri¬ bution in the coal bed, the third test was conducted at various coal feed and air flow rates [Table 4], 58 Mukherjee and Hahn Tuyeres location outside tuyeres A * 0.203m (dla.i Inside tuyeres, top B * 0.165m (dia.)

Traditionally, economic systems in tropical Africa have rewarded those populations with large numbers of offspring, thus partly accounting for the desire for very high fertility among individuals in these populations [19]. The common denominator of a reproductive imperative, grounded, at least in part, in social or religious tradition, can be identified in other populations also reported to have relatively high TRs . For ex¬ ample, in a study of multiple births among individuals in the Bola tribe of the island of New Britain, Scragg and Walsh [135] reported a multiple- birth incidence of 3.17%, a rate two to three times greater than the observed rates among four local control populations (two communities on New Ireland and two on Bougainville Island) . The incidence of multiple births in these two communities is 1.15% or 1 in 87 births, a figure that approximates most Caucasian groups [135]. The main component of the multiple -birthing phenomenon among the Bolas of New Britain is attributed to DZ twinning. Scragg and Walsh [136] reported that during the time-period which was encompassed by this study (the years between 1954 and 1966, inclusive), the Bola area com¬ prised about 400 square miles with a population ranging from 3,063 to 4,609 individuals. They also reported that the area has been under the influence of a Roman Catholic mission for over 40 years [136] and de¬ scribed the Bola people as "entirely Roman Catholic" [135]. The authors concluded that some as-yet-unidentified environmental factor might be influencing pituitary gonadotropin levels in Bola women causing the 67 Abbott -King observed multiple-birthing phenomenon. In comparing nutritional factors, the authors concluded no significant difference existed between the diet of the Bolas and the diet of the individuals in the New Ireland and Bougainville populations. They noted this incidence of multiple-birthing to have been a local phenomenon not found anywhere else in Papua or New Guinea . Comparatively, the religion factor seems significant also in a study by Wyshak [158] regarding the reproductive and menstrual characteristics of mothers of multiple births and mothers of singletons in the United States. Wyshak [158] reported Catholic women as having a greater number of live births, pregnancies, and maternities than women of other reli¬ gions. The twinning incidence in Chile, a predominantly Roman Catholic country, is reported to be high at 57 per 1,000 births [135] and a study of twinning in Mexican-Americans [ 4-7 ] , a predominantly Roman Catholic population, showed Mexican-Americans as having a higher TR when compared with U.S. populations of Blacks, Anglos, and Asians. In a study of twin¬ ning in the Utah Mormon population, Carmelli and others [21] reported that when compared to other U.S. Caucasian populations, Mormons consis¬ tently showed higher twinning rates. Both Mormon and Catholic religions encourage large family size as do the Yoruba and Bola cultures. Based on inference from the examples discussed above, it seems likely that investigation of the possibility that religious culture might provide a proximal stimulus for neurohormonal conditions, which would favor multiple ovulation, appears warranted. And, assuming that such an apparently causative mechanism exists, the question thus arises: through what neurohormonal pathways might it conceivably operate to produce the final outcome of multiple ovulation? This line of inquiry may also shed light on another unexplained phenomenon reported in twin literature: elevated TRs among postwar births. TWINNING, POSTWAR BIRTHS, AND REPRODUCTIVE IMPERATIVE As if to compensate for war mortality or delayed reproduction, the frequency of twin births tends to increase during postwar periods. Allen and Schachter [7] reported an increase in TR in the United States after World War II. Allen [4, 5] has suggested that the psychological state of the female, influenced by the pituitary, may have enhanced production of pituitary gonadotropins during this time period, thereby enhancing the probability of double ovulation. However, no characteri- zation of the hormonal pathway (s) whereby such a mechanism might operate has been offered. Torgersen [146] reported a postwar increase in triplet births greater than that of any earlier period in Norway after World War II. Parisi and Caperna [117] reported a sudden increase in DZ TRs in Italy associated with the end of World War I. The authors of these latter two studies have been unable to account for these phenomena in terms of factors usually associated with such variation (namely, maternal age, parity, and nutritional effects). Parisi and Caperna [117] have suggested that psychosocial factors may influence rates of double ovula¬ tion and that this may account for some variations in TRs, but like other studies, details of the neurohormonal pathways whereby such a mechanism might influence multiple ovulation have not been proposed. 68 Human Twinning A postwar peak in TR is also reported to have occurred in the United States in 1919 [5], Similarly, in a series of studies on worldwide secular trends in TRs over the two decades 1957-1978 [61, 62, 64] James [64] reported an unexplained increase in twin births in the United States during the 1970s, while TRs in other developed countries showed a de¬ crease or stabilization during these years. Allen [6] further examined this increase in U.S. TRs between 1964 and 1983, standardizing for mater¬ nal age and parity. His analysis approximated 1964 as the low point for U.S. TRs, showed a 10% drop in TRs among both Blacks and Whites for 1969- 70 (which may be an artifact of a 2-year reporting hiatus encompassing these years) with continuous increase in White TRs thereafter, and showed increased TRs among Blacks beginning in 1972, following a stable rate for earlier years (the 1969-70 drop being an exception) . Allen ruled out medical ovulation stimulants as a causative factor because of the distri¬ bution of increased TRs with respect to race, maternal age, and year. In light of these data and the aforementioned postwar twinning studies, I suggest it noteworthy that the 1970s represent a postwar period in the United States. Military discharges were ongoing throughout the Vietnam Conflict period; the highest number totalling in the millions occurred from 1969-1971, and complete withdrawal of all U.S. forces was attained by January 1973 [147], While battle deaths reported for 1968 were the highest reported for any ye~r during this war period at 14,589, those of the adjacent years 1967 and 1969 were reported to be 9,377 and 9,414, respectively [147]. Approximately 75% of the total casualties incurred through battle deaths in Vietnam from 1961-1972, occurred during the period 1967-1969 [147]. Relatedly, examination of data presented in a decadal study of TRs in Gorlitz, Germany, during 1611 to 1860 [128] shows coincident occur¬ rence of twinning peaks in postwar years. The authors of the Gorlitz study did not take postwar relationship into account and supposed that some seasonally epidemic factor may have played a role in causing the twinning peaks. The authors reported Gorlitz as "an important medieval town on the main road between Eastern and Western Europe." They also reported a nearly constant population of about 10,000 and a birth rate of about 250/year during the years encompassed by this study, except for increases in TRs observed in the decades under study. It is noteworthy that the highest TR (2.04%) of the decades encompassed by this study occurred in the decade 1651-1660 following the Thirty Year War (1618- 1648) . Also noteworthy is the fact that this war has been described as frightful in terms of the population losses Germany suffered as a result of military action and disease. The TR increase is followed by decades of medium (defined by the authors as 1.00-1.50%) to low (less than 1.00%) TRs until the decade 1761-1770 following the Seven Years War (1756-1763) when the TR increased to over 1.50%. The TR for the preceding decade was less than 1.00%. Thereafter, the TR remained high-to-medium in alternat¬ ing decades until it dropped to low levels beginning with the decade 1811-1820 [128]. This low level alternated with medium levels in sub¬ sequent decades until 1860, the last year encompassed by this study. The stress of war manifests itself in humans through anxiety, chron¬ ic depression, and certain disease states characteristic of chronic 69 Abbott-King tension [103], Elevated TRs appear to have coincided with the cessation of wartime, and therefore, perhaps, with the cessation of a proximate stress stimulus. From this observation, it can tentatively be supposed that examination of physiological changes associated with stress and post- stress conditions would provide supporting or refuting evidence for twinning incidence as a stress-related phenomenon. Existing data on the relationship between stress and reproductive physiology does provide supporting lines of evidence which are discussed in the following sec¬ tions. However, studies utilizing contemporary assaying techniques on mothers of DZ twins are necessary to more fully evaluate this possible interaction and to ascertain a direct correlation. NEUROHORMONAL PATHWAYS FOR MULTIPLE FOLLICULAR RECRUITMENT, MATURATION, AND OVULATION Several lines of evidence indicate that pituitary gonadotropin hormones, FSH and LH, play a regulatory role in dizygotic twinning. Numerous studies on human infertility and its treatment indicate that poly- ovulation is related to levels of the pituitary gonadotropic hormones [157]. In a study by Shaw and others [138], twin pregnancy occurred following desensitization of the pituitary using an LHRH analogue, and administration of FSH in conjunction with down- regulation of the hypothalamopituitary axis. Suppressed levels of LH thus attained indicate that LH is not as important as FSH for follicular recruitment and maturation, requisite events for double ovulation. Direct evidence for elevated pituitary gonadotropin levels associated with twinning comes from Nylander's studies on Yoruba mothers of twins [109-112] discussed previously, and from studies by Martin and others [92, 93] where a study of mothers of twins in an Australian population showed higher serum FSH levels in mothers of twins when compared with mothers of singletons [92]. Conversely, serum gonadotropin levels in a Japanese population studied by Soma and others [142] showed very low levels and Japanese populations are reported to have the lowest TRs. It is expected that if more than one follicle were recruited and matured for ovulation, follicular estradiol levels would be elevated during the midfollicular phase [92, 93, 164] and investigations show results consistent with this expectation [92, 93]. A number of studies have described binovular human ovarian follicles [48, 54, 66, 70, 115, 116, 139] and it has been suggested that these follicles may contribute to the incidence of DZ twinning [54, 66]. Zeilmaker and others [163] reported recovery of viable oocytes from a- human binovular follicle subsequent to gonadotropin and clomiphene treatment for in vitro fertili¬ zation. Although it is likely that these binovular follicles were the result of hormonal treatment, the natural occurrence of binovular fol¬ licles is not ruled out [164], Clomiphene treatment accompanied by temporary estrogenic hormone withdrawal induces multiple follicular maturation via increased secretion of gonadotropins [164], Gonadotropin stimulation has been closely linked to the incidence of human binovular follicles [66, 70, 116]. 70 Human Twinning Gonadotropin- Releasing Hormone and Pituitary Gonadotropins Gonadotropin-releasing hormone (GnRH) , a hypothalamic decapeptide , is reported to regulate gonadotropin secretion from the anterior pitui¬ tary [91]. Several lines of evidence support pulsatile mode of GnRH release as being essential for gonadotropin secretion and frequency of GnRH secretion as important in altering gonadotropin secretion. Pre¬ sumably, alterations in GnRH frequency affect recruitment and maturation of more than one follicle via alteration of FSH/LH ratios at critical phases of the menstrual cycle. Pulses of GnRH have been shown to re¬ instate secretion of LH and FSH in GnRH- deficient humans and monkeys and continuous infusions of GnRH have been shown to desensitize the release of gonadotropins [11, 57, 80, 90, 91, 148]. Frequency of GnRH stimulus has also been shown to regulate secretion of FSH and LH in the following: in humans, sheep, and monkeys one GnRH pulse/hour maintains FSH- and LH- release [91, 154]; one GnQH pulse every 3-4 hours results in elevation of FSH and reduction in LH-release [25, 91, 118, 154]; three GnRH pulses/ hour result in reduced LH- and FSH-release in plasma (reduction of LH being due to its 90-100 minute half-life) [91, 154], Therefore, slow GnRH-pulse frequency may favor FSH-release from the anterior pituitary [91] . With regard to GnRH control of amount of LH released, it has been shown in sheep that amplitude of LH-release decreases with frequent GnRH pulses and increases with slowed GnRH pulses [25, 91], Pituitary Gonadotropins and Gonadal Steroids LH stimulates secretion of gonadal steroids and secretion of pro¬ gesterone and prostaglandins, substances necessary for ovulation [145], FSH regulates follicular growth and maturation. Figure 1 illustrates generalized hormonal pathways through which gonadotropin secretion is thought to be regulated in the human female . GnRH secretion frequency is reported to be inhibited by the gonadal steroid estradiol [91], Con¬ versely, LH pulse frequency is increased by estradiol [68] . Estrogen effects may be dependent on the duration or magnitude of hypothalamic exposure to estradiol [91], Supporting data show LH-pulse-frequency increases with increased plasma estradiol during the late follicular phase of the menstrual cycle [10, 124], Estrogen is produced by the maturing follicle and is the stimulus for the LH-FSH-peak associated with ovulation [2, 145]. Progesterone's inhibitory effect on LH has been observed in the luteal phase of the menstrual cycle [10, 41, 124, 160], In other studies, the gonadal steroid progesterone has been shown to inhibit LH pulse frequency [94, 143]. Both estradiol and progesterone can modify GnRH secretion amplitude and frequency patterns, altering the differential secretions of FSH and LH during the menstrual cycle. Further, progesterone has been shown to enhance the response of LH to GnRH after exposure to estradiol [75, 91] and the combined effect of these steroids are thought to be responsible for the LH and FSH peak at midcycle [84] usually associated with ovula¬ tion. While estradiol has been shown to positively influence LH levels, it has also been shown to inhibit FSH secretion [88, 91,96]. It is thought that gonadal steroids affect pituitary gonadotropin secretion by changing levels of endogenous opioids and hypothalamic catecholamines [91]. 71 Abbott-King o a. s A a. t STIMULATORY -► INHIBITORY /A /V — >L H FSH< - ^ s. \ / \ / 7 OVARY GRANULOSA CELLS \1/ FOLLICULAR RECRUITMENT.

Secretory structures and products are shown in boxes and regulatory influences are indicated with arrows (see text for references) . Opioids, Catecholamines , GnRH , and Gonadotropin Secretion The hypothalamus contains high concentrations of opioids and their receptors [56, 58]. Beta-endorphin is also contained in the cortico- trophs of the anterior pituitary and there is some evidence for met- enkaphalin in pituitary somatotrophs [58, 150]. Co-release of beta- endorphin and adrenocorticotropic hormone (ACTH) is reported to occur in plasma following stressful stimuli [58, 140]. Opioids are reported to suppress FSH and LH in humans [29, 50, 58, 125, 144] and to have an inhibitory effect on GnRH pulse frequency [91]. Opioids are also thought to mediate inhibitory effects of ovarian steroids [82, 91], Figure 2 schematically summarizes regulatory pathways reported for opioids, GnRH, and gonadotropins. 72 Human Twinning Figure 2. Schematic diagram schowing inhibitory action of opioids on GnRH, and stress - induced secretion of pituitary peptides (see text for references) . Secretory structures and products are shown in boxes and regulatory influences are indicated with arrows . Increased activity of opioids and consequent inhibition of GnRH secretion has been implicated in hypothalamic amenorrhea and anovulation [22, 23, 51, 71, 72, 91, 121, 132], Physical and psychological stress as well as self-imposed loss of weight are reported to result in increased hypothalamic opioid activity and consequent reduction of GnRH pulse fre¬ quency, producing amenorrhea, and anovulation [74, 89, 91, 134], Opioids are thought to operate by modifying firing patterns of neurons that secrete GnRH causing alteration in GnRH pulse- frequency [91], Various forms of stress are reported to release corticotropin re¬ leasing factor (CRF) from the hypothalamus and experimental data on human pituitaries demonstrate increased release of both adrenocorticotropic hormone (AGTH) and beta- endorphin in response to CRF [40] . In their hypothesis on the role of endogenous opioids in ovarian function, Ferin and others [40] postulated that amenorrhea .may be caused by abnormal activity of hypothalamic beta- endorphin characterized by continuously low or sustained high activity, rather than the normal sequence of high and low periods of activity characteristic of the normal menstrual cycle (beta-endorphins increase during the luteal phase [40], for instance). Such abnormal opioid activity would lead to "sustained high or continu¬ ously low GnRH oscillator frequency" and improper ratios of gonadotropins necessary for morphological ovarian changes in the normal menstrual cycle [40] . Subsequent studies have produced results consistent with this hypothesis [71, 72, 123], Observations on chronic opioid treatment have shown loss of responsiveness to opioid stimulation and massive increase of LH upon withdrawal of the treatment [82] (Table 1). 73 Abbott-King Table 1.

GnRH pulse frequency Gonadotropin levels Tonically- slowed GnRH- pulse frequency resulting in low FSH-LH levels or disproportionate FSH/LH ratios favoring anovula¬ tion/amenorrhea . *Opioids are thought to prevent excessive release of catecholamines [30, 52, 59, 73, 87] and may, therefore, alter NE/E ratios producing a net effect on GnRH-pulse frequency. Increased release of catechol¬ amines may result in increased release of opioids that modulate ex¬ cessive release of catecholamines through autofeedback [59]. Like opioids, catecholamines such as epinephrine (E) and norepi¬ nephrine (NE) are thought to change the firing pattern of GnRH- secreting neurons, consequently altering GnRH pulse frequency [91]. E and NE have been shown to affect the frequency of GnRH pulses in rats [67] and in primates, and catecholamine blocking agents have been shown to slow LH pulse frequency [69]. These data imply a stimulatory role for catechol¬ amines on hypothalamic GnRH-release . Dopamine, a precursor in the bio¬ synthetic pathway of NE and E, is reported to cause a decrease in circulating levels of LH in humans, when orally infused [145]. It has 74 Human Twinning been suggested that norepinephrine exerts a stimulatory effect on GnRH while dopamine exerts an inhibitory effect on GnRH [145, 159] . However, while continuous administration of dopamine in humans causes a decrease in circulating gonadotropin concentrations, withdrawal of treatment results in a rebound effect causing circulating concentrations of gonad¬ otropins to overshoot original baseline levels [145] (Table 1). The sympathomedullary- adrenocortical system responds to physical and psychological stress in a number of ways including NE- release from sympathetic nerves, E-release from the adrenal medulla, ACTH from the anterior pituitary, and glucocorticoids from the adrenal cortex. Ca¬ techolamines also are reported to stimulate release of ACTH from the anterior pituitary and are in turn regulated by glucocorticoids [9]. E is reported to sensitize the anterior pituitary to the action of CRF on ACTH-release [9], Stress has been shown to activate the sympathetic adrenomedullary system to produce elevated plasma levels of catechol¬ amines. Social stresses such as public speaking [9, 76] and harassment [9, 32] have been shown to raise E levels. A rise in NE levels is also reported to result from public speaking stress [9, 76] though to a lesser extent than those of E. Basal levels of E and NE have been shown to increase in relation to level of anxiety in depressed subjects [9, 85]. Other forms of stress such as hypoglycemia, physical stress, and thermal stress are also reported to increase plasma levels of catecholamines [9], Studies support a modulatory role for opioids in excessive release of catecholamines [30, 52, 59, 73, 87] and the human sympathoadrenal system characteristically contains high concentrations of the opioids beta-endorphin and met-enkaphalin [59], Opioid peptides may be released from splanchnic nerve endings to modulate catecholamine - release from adrenal chromaffin cells or may be released from chromaffin cells in the adrenal medulla to exert catecholamine -modulating autofeedback on the cells [59], STRESS -RELATED NEUROHORMONAL CONDITIONS FAVORING MULTIPLE FOLLICULAR RECRUITMENT AND MATURATION: . A HYPOTHETICAL SCHEMA Observations on the suggested role of pulsatile, hypothalamic GnRH- release in regulating FSH/LH release from the anterior pituitary, the modulatory roles suggested for catecholamines and opioids on GnRH- re¬ lease, the modulatory role suggested for opioid peptides in preventing excessive release of catecholamines, and the release of opioids and catecholamines in response to stressful stimuli provide a valuable con¬ struct in which to examine a possible role for psychosocial stimuli in twinning incidence. In Table 1, I propose tentative pathways accom¬ modating existing data, whereby stress - induced alterations of opioids and catecholamines might contribute to physiological conditions favoring twinning. According to this hypothetical schema, the stressed condition sets up antecedents for a rebound effect favoring relatively high FSH and LH levels. These elevated gonadotropin levels might in turn favor re¬ cruitment and maturation of more than one follicle, or perhaps, binovular follicular development. It is significant that Nylander [111, 112] and Martin and others [92] found elevated FSH levels in DZ twinning mothers during the follicular phase. Existing data indicate a finely tuned 75 Abbott-King regulatory role for GnRH pulse -frequency variation in controlling gonad¬ otropin ratios during various phases of the menstrual cycle to maintain normal menstrual and ovulatory cyclicity. Disturbances in hypothalamic GnRH- release have been shown to result in varied FSH/LH ratios and can therefore be presumed capable of disturbing the normal events of the ovulatory cycle. This hypothetical schema is highly simplified and does not preclude the possible interaction of other neurohormones and gonadal steroids within the system. Further studies using specific agonists, antagonists, radioimmunoassays, and sufficiently sensitive radioenzymatic techniques to evaluate the possibility of these and other interactions, are clearly necessary. It is an objective of this synthesis to underline the impor¬ tance of this line of inquiry to present and future research on twinning. Several falsifiable predictions derive from the synthesis put forth in this paper and the hypothetical schema postulated therefrom. The main tenets of my hypothesis are summarized as follows, and unless otherwise noted, are referenced in previous sections. A. Demographic and physiologic studies of twinning have produced the following observations: 1. Twinning tends to occur in large families. 2. The frequency of twinning increases after wartime. 3. Levels of FSH and LH are higher in mothers of twins than in mothers of singletons. 4. Twinning incidence increases with increased maternal age [17, 18, 35, 99, 122, 156]. B. Studies on pituitary gonadotropin regulation of follicular recruitment, maturation, and ovulation show results compatible with the above findings on twinning incidence, assuming a neuroendocrine relation: 1. Pituitary gonadotropins, FSH in particular, are important in follicular recruitment, maturation and ovulation, and at high levels promote multiple ovulation. 2. GnRH pulse frequency and amplitude are postulated to regulate gonadotropin levels. 3. Catecholamine and opioid peptide neurotransmitters stimulate or inhibit GnRH pulse frequency and are thereby postulated to play a regulatory role in gonadotropin secretion. 4. Catecholamines and opioid levels co-vary with emotional state and excess hypothalamic opioid-release is implicated in amenor¬ rhea and anovulation. C. If levels of these neurotransmitters are consistently correlated with stressed emotional/psychological states of twin mothers, then certain heretofore unexplained twinning phenomena might be correlated with stress - related events affecting female neurophysiology. Demographic and physiologic findings are consistent with this hypothesis and the following predictions should hold in order to confirm it: 1. Variations in levels of catecholamines and opioid peptides in mothers of twins should show consistency with GnRH-pulse 76 Human Twinning frequency variations and variations in gonadotropin levels which would favor multiple ovulation. 2. Populations whose traditional culture, religion, or social structures do not encourage large family size should show comparatively low twinning incidence . 3. Within a cohort of women of increased maternal age, twinning rate should be higher among primaparous mothers than multiparous mothers; the ending of a woman's reproductive years signalling a "reproductive imperative" in the neurophysiology of older mothers who have not yet successfully born children. Results of at least one study [122] support this prediction. 4. Twinning rates should increase after stressful man-made or natural events which result in high mortality, e . g . , plague, famine, war (supported, in part, by postwar studies cited in a previous section) . 5. Twinning incidence should increase with increased migration from urban to rural areas , urban areas representing chronically high- stress environments and rural areas representing environments of intermittent stress (see Discussion for supporting studies) . 6. Twinning incidence should be higher among native inhabitants of island populations (see Discussion for supporting studies) when compared with the mainland inhabitants of their ancestral lineage; islands representing colonization sites and less stable, intermittently stressful environments when compared with mainland environments . DISCUSSION Confirmation of the predictions derived from the hypothesis proposed in this paper would support a related hypothesis proposed by Rushton [131] that: 1) DZ twinning is a r-selected reproductive strategy in the human species characteristic of individuals living in unstable environ¬ ments and the degree to which an individual is K- selected manifests itself in social behavior and physiology and 2) the process of sociali¬ zation itself may cause humans to adopt an r- or K-strategy based upon how predictable they perceive their environment to be [126, 151, 152]. The twinning phenomena described in this paper show relationships predicted by population regulation theory, although anomalies do exist. (Deviations at the empirical level are expected of the hypothetical schema postulated in this paper and therefore, it is expected to be refined necessarily, through further experimentation. However, existing data merits its investigation.) Although population regulation is most commonly discussed in terms of mechanisms which reduce the population from a high level in relation to resources and space, a phenomenon known as "population limitation" [28], it is also supposed that such a mecha¬ nism could operate to increase the population in response to a low population level [43], thus maintaining an optimal density in relation to environmental limits. Human twinning phenomena discussed in this paper collectively manifest some of the characteristics of a dens ity- dependent , self -regulating mechanism and as such, perception of population density would be expected to play an integral role in limiting or expanding the human populations discussed. Human reactions to population density are 77 Abbott-King highly variable [26, 43] and if human twinning is part of a self- regulating system in humans, then mothers of twins would be expected to show cor- relates of perceptual reactions to density accordingly, when compared with mothers of singletons. This assumption is readily falsifiable through appropriate experimental manipulations. The line of reasoning being developed here considers the possibility that the sensory-perceptual systems of some humans is part of a complex of feedback loops involving their reproductive system and cognitive functions in such a way as to confer them the ability to compensate for prenatal or postnatal familial mortality. Any one human's response to density is mediated by many processes including interpretation of a situation and its consequences for him/herself, and social organization affects density-sensitivity [43], Further, it is expected that the extent to which self-regulation characterizes species as a by-product of individual selection, the regulatory mechanisms and systems of regulation would be expected to be specific to populations and closely adapted to their particular environment [26], Twinning phenomena discussed herein appear consistent with this expectation. Such a self -regulating mechanism may account for high TRs observed in rural vs. urban populations [36-39, 45, 46, 101, 130, 146] and in island populations [36, 92, 98, 119, 120, 135, 136]; rural environments representing optimal density/resource situations and islands repre¬ senting sites of optimal density/resource conditions upon initial colonization. Similarly, with regard to postwar increases in TR, perception of optimal density/resource conditions during postwar periods may operate through neurohormonal pathways to increase reproductive potential via twinning. Perception of optimal density/resource condi¬ tions might contribute to relief from stress characteristic of the postwar period. Finally, such a density-dependent mechanism operating, in. part, through perceptual systems in humans, may account for the association of twinning with individuals of specific religions. Self- perception of whether or not one has fulfilled one's social, religious, or personal obligation to successfully reproduce, may result in neuro¬ hormonal conditions which favor twinning. This may account for the relatively high twinning incidence observed among individuals in the Yoruba, Catholic, and Mormon populations previously described. It would be informative to investigate postwar TRs in terms of the religious components of the populations studied, to see if the observed high TR is not predominantly due to TR in individuals of religious groups which encourage large family-size. This possibility is as yet unexplored. The premise of this paper has been that human twinning incidence can be observed to vary in a seemingly compensatory manner, in response to changes in the physical or cultural environment. This premise supports selection at the individual level, and any collective advantage to the group (e.g., Catholics, Yorubas , and Mormons) is viewed as a fortuitous result of advantage to the individual (as it is viewed of other species exhibiting compensatory mechanisms [141]). The relative paucity of information on neurohormonal pathways involved in DZ twinning could, I be- lieve, be mitigated by study of the relationships postulated in this synthesis and a greater understanding of the enigmatic variations ob- 78 Human Twinning served in human twinning rates gained, through the lines of inquiry herein proposed.

Dawkins Department of Zoology and Wildlife Science and Alabama Agricultural Experiment Station Auburn University , AL 36849 ABSTRACT As in other insects, vitellogenin (VG) is synthesized and secreted by the fat body of adult female crickets during vitellogenesis. In some species, notably certain dipterans , the ovary also produces VG. This study examined the ovary of Acheta domesticus for VG- synthesizing activi¬ ty. Isolated ovarian and fat body tissue from 48 to 60-hour-old adult females was cultured in vitro with uC-leucine or 35S -methionine for 2-4 h at 30°C. Tissues and media were assayed for labeled VG polypeptides by immunoprecipitation and by autoradiography after SDS -polyacrylamide gel electrophoresis. The results indicated that the cricket ovary produces VG. Evidence was also obtained for the synthesis of two high molecular weight intracellular VG precursor polypeptides by the fat body and ovary of adult females. The factors regulating ovarian VG synthesis and the relative contributions of fat body- and ovary-derived VG to the total egg yolk protein in the cricket are not yet known. INTRODUCTION Vitellogenin is the blood borne precursor protein for the major egg yolk protein(s) for animals with lecithal eggs. Insect VG is produced by the fat body, secreted into the hemolymph, and sequestered by vitellogenic follicles via receptor-mediated endocytosis (Engelmann, 1979, Telfer et al., 1982). Immunoreactive VG is first detectable in the hemolymph of virgin female Acheta domesticus between 14 and 24 hours after ecdysis to the adult (Benford and Bradley, 1986). By 38 hours, terminal follicles are vitellogenic, and fully grown chorionated oocytes appear in the lateral oviducts on the 5th day of adult life (Bradley and Edwards, 1978). As in other insects (Wyatt and Pan, 1978) , the fat body is a major source of VG in the cricket (Cox, 1988). In a few insects, VG also appears to be synthesized by the ovary. Previtellogenic ovaries from several Drosophila species produce fully- developed oocytes after being transplanted into adult male or even larval hosts (Bodenstein, 1947; Srdic et al . , 1979), suggesting autonomous VG synthesis by the ovary, and immunoprecipitable VG is synthesized by the ovaries of Sarcophaga bullata (Huybrechts et al . , 1983), D. melanogaster (Brennan et al., 1982), and Mu sea domestica (de Bianchi et al . , 1985), So far there has been no direct demonstration of extra- fat body VG syn- ^anuscript received 25 October 1988; accepted 30 January 1989. 92 Bradley, Chang, and Dawkins thesis in crickets. The possibility of ovary-derived cricket VG is suggested by the facts that the appearance of newly made hemo lymph VG in A. domesticus is juvenile hormone (JH) -dependent (Benford and Bradley, 1986) and that a few normal -appearing oocytes are produced in some (12%) adult A. domesticus females allatectomized during their last nymphal instar ( Chudakova et al . , 1967). The latter study was done prior to identification of cricket VG polypeptides (Bradley and Edwards, 1978) and so did not rule out the possible uptake of nonVG hemolymph proteins by developing follicles in the allatectomized animals. The present study provides immunological and electrophoretic evidence for VG synthesis in the ovary of A. domesticus . Also reported is the tentative identification of unprocessed VG polypeptide precursors in the fat body and ovary of females during vitellogenesis. MATERIAL AND METHODS Animals Acheta domesticus (L.) was purchased in mixed (females and males) batches of 1000 last instar nymphs from Monroe Cricket and Grub Farm (Monroe, GA) , and stock populations of these were maintained as previously described (Bradley and Edwards, 1978). Newly molted adults were isolated from the stock population, placed in individual plastic petri dishes (90 mm diameter x 13 mm deep) , supplied with food (Pulverized Little Friskies , Carnation, Ca. , Los Angeles, CA) and water ad libitum, and maintained in a ventilated incubator (Percival, Boone, IA) at 27 - 30°C (70% r.h.) on a 12 : 12L/D photoperiod until used in the experiments described below. The time of ecdysis of the adult was estimated on the basis of cuticle coloration and degree of wing inflation (Bradley, 1976) to within 5 minutes for animals used in the ligation experiment and to within 2 hours for those used in all other experiments. In vitro labeling of polypeptides Tissues were cultured in plastic tissue culture plates (Ace Scientif¬ ic, Model S-MRG-90) or 10 mm diameter glass shell vials. These and all dissecting equipment were sterilized by a 1-2 hour exposure to UV light (Sylvania bulb G30T8) inside a benchtop culture hood (Lab Con Co.). Prior to dissection, crickets were rinsed briefly in deionized water, surface sterilized by immersing 45-60 seconds in 0.2% HgCl2 , and then rinsed twice in sterile deionized water. Ovaries and fat body were removed from the dorsal side of the abdomen, and muscle tissue was collected from hind femurs. Each organ or tissue piece was placed directly into a shallow glass dish containing sterile Grace's unmodified insect medium (Gibco)i All visible fat body adhering to the ovaries was removed with the aid of a dissecting microscope. Tissues were then transferred to individual culture wells or vials containing measured amounts of Grace's unmodified culture medium. For each experiment, label previously diluted to an appropriate activity with culture medium was added to each culture vessel within a 60 second period. The wells (or vials) were then covered with parafilm, and the plates were wrapped in cellophane and incubated with gentle shaking at 30° in a shallow water bath. 93 Vitellogenic Protein Synthesis Tissues for which VG- synthesizing activity was quantitated by immuno- precipitation were incubated for 4 hours in 350 ^Ci of 1AC-leucine (342 mCi/mmol, New England Nuclear). Tissue from four crickets was incubated in each vial which contained either four ovaries, fat body approximating that in two whole abdomens, or leg muscle approximating that in two hind femurs. After the incubation period, the tissue and culture medium in each vial were homogenized at 0°C in the presence of 0.1 mM phenylmethyl- sulfonyl fluoride (Sigma), and aliquots of the homogenate were stored at 90°C for later estimation of labeled VG, TCA precipitable label, and total protein. For the electrophoretic analysis tissues were incubated for 2 h in 27 pi of culture medium containing 10 pCi of 35S -methionine . Ovary pairs and/or about 50% of the abdominal fat body from each individual were cultured separately. After the incubation period, tissue from each culture well was rinsed twice in culture medium and then homogenized in 35 pi of fresh medium. These homogenates and the original culture medium for each tissue sample were stored at -90°C until electrophoresis. Antiserum preparation and immunoprecipitation assay for newly synthesized vitellogenin Antiserum was raised in rabbits as previously described (Chang and Bradley, 1982) using a protein extract from fully grown cricket oocytes as the antigen. The antiserum was exhaustively absorbed with hemolymph from adult males and last nymphal instar males and females, and its specificity was tested by Ouchterlony immunodiffusion. The absorbed antiserum reacted only with adult female hemolymph and egg yolk protein extracts, forming a single fused precipitin band opposite these antigen sources. Labeled VG in tissue homogenates was estimated using the immunoassay described by Chang and Bradley (1982) . Estimation of 14C- leucine incorporation and total protein ^C-labeled protein was precipitated in 10% TCA, transferred to glass filters (GF/A, VWR Scientific) , washed, and counted by liquid scintilla¬ tion as previously described (Chang and Bradley, 1982). Total protein in tissue homogenates was estimated according to Lowry et al . (1951) using bovine serum albumin in 0.4 M NaCl as a standard, and samples were read at 560 nm against 0.4 H NaCl blanks. Polyacrylamide gel electrophoresis Samples to be electrophoresed were thawed, and a half volume of solution containing 0.186 M Tris-HCL pH 6 . 8 , 6% sodium dodecyl sulfate (SDS) , 30% glycerol, and 15% 2 -mercaptoethanol was mixed with each tissue homogenate and culture medium sample. The samples were then heated for 2 min. at 100°C after which the tissue homogenates were microfuged for 3 min. in order to sediment insoluble material. SDS -polyacrylamide gel electrophoresis was performed at room temperature according to Laemmli (1970) in a 15-lane, 180 x 160 x 1.5-mm, 6-8% acrylamide gradient slab gel. Ten to 30 p\ samples of either pooled or individual tissue homoge¬ nates or culture media were applied to each sample well. A constant 85 94 Bradley, Chang, and Dawkins V were applied until the bromophenol blue tracking dye reached the stacking gel-running gel interface; thereafter, electrophoresis was at 110-125 V until the dye reached the bottom of the running gel. After electrophoresis, the separate polypeptides were fixed and stained with Coomassie brilliant blue according to Laemmli (1970). The destained gels were photographed and dried onto filter paper with a Bio-Rad gel slab dryer . Autoradiography and photography Autoradiographs of dried polyacrylamide gels containing 35S- methionine- labeled polypeptides were produced using Kodak XAR-5 film exposed for varying periods of time at -90°C. The film was developed by standard procedures with Kodak x-ray developer. Autoradiographs were photographed over a light box using Kodak Technical Pan Film 2415 and a deep orange filter. The film was developed for high contrast. Statistical procedures Each mean + standard error reported in Table 1 was derived from three samples, each containing tissue from four animals. The means were com¬ pared using Student's one-tailed t-test. RESULTS Tissue-specificity of in vitro vitellogenin synthesis To quantitate in vitro VG- synthesizing activity of the fat body and ovary, an immunoprecipitation assay for newly synthesized VG was used. In two separate experiments, VG- synthesizing activity, expressed as the amount of label incorporated into immunoprec ip i table VG per unit of tissue protein, was about three times greater in the fat body than in the ovary (P<.05) of 48 to 60-hour-old virgins (Table 1). Nevertheless, the amount of immunoreactive , labeled protein produced by the ovary was significantly greater than that from either the ovaries or fat body of last instar nymphs, or from leg muscle tissue from adult females (P<.05; Table 1). Vitellogenin represented 18-20% and 4-5%, respectively, of the TCA precipitable 14C- leucine incorporated by the fat body and ovary of adult females during the culture period. Since both ovaries and as much abdomi¬ nal fat body as possible were collected and cultured from each experimen¬ tal animal, the relative contributions of the ovary and the fat body to the total vitellogenin- synthesizing activity per animal could be estimated from the in vitro activities of these tissues. Assuming that the fat body and ovary are the only sites of VG synthesis, it was estimated that the ovaries were producing 16-21% of the newly synthesized VG in the abdomens of 48 to 60-hour-old females. Electrophoretic identification of vitellogenin precursor polypeptides Patterns of in vitro protein synthesis were examined in various tissues by autoradiography of 35S- labeled polypeptides separated electro- phoretically in SDS -polyacrylamide gels.

Exposure times for images in lanes 6-9 and for lanes 8' and 9' were 5 days and 24 days, respectively. Note that labeled ovarian polypeptides which comigrate with fat body VG precursor polypeptides are detectable only after long exposure. females with vitellogenic follicles synthesized two high molecular weight polypeptides which were precipitated specifically by an antiserum for cricket VG and vitellin (VN) (Fig. 1). Neither polypeptide was produced by fat body from adult males or last nymphal instar females at levels sufficiently high for detection by autoradiography. Therefore, these two female-specific fat body polypeptides were tentatively identified as precursors of the processed VG polypeptides previously identified in the hemolymph of A. domesticus (Bradley and Edwards, 1978). Autoradiographs produced by extending the exposure period beyond three weeks revealed two minor 35S-labeled polypeptide products of vitellogenic ovaries which co¬ migrate with the putative fat body VG precursors (Fig. 1). 97 Vitellogenic Protein Synthesis DISCUSSION Evidence for VG synthesis in the ovary of the cricket, A. domes t icus , was obtained by two methods: liquid scintillation of immunoprecipitates and autoradiography of labeled polypeptides separated in polyacrylamide gels. Evidence for ovarian production of VG has been reported for only one other orthopteran (Wyss-Huber and Luscher, 1975). These authors presented electrophoretic and immunological evidence that the female - specific vitellogenic protein of Leucophaea maderae is synthesized by isolated ovarioles and the ovarian connective tissue sheath, as well as by the fat body. Moreover, it appeared that the rate of ovarian VG synthesis was highest during a period of follicle growth when the corpora allata are active, suggesting that JH may regulate ovarian as well as fat body (Brookes, 1969) VG synthesis in L. maderae. Although the whole ovary did produce VG in vitro, fat body tissue within the ovary or the ovarian sheath was suggested to be responsible for this activity. Ovarian VG synthesis is well documented in the Diptera. In D. me- lanogaster , the follicular epithelium of vitellogenic oocytes synthesizes all three VG polypeptides and produces 10-35% of the total messenger RNA in the animal for each of these (Brennan et al., 1982). The ovaries of M. domestica synthesize and secrete VG in vitro (de Bianchi et al . , 1985), and ultrastructural studies suggest that some yolk protein synthesis also occurs in the follicle cells of this species (Chia and Morrison, 1972) . Ovary transplantation experiments gave evidence for VG synthesis by the ovary in D. mercatorum and D. hydei (Srdic et al., 1979), and in S. bullata both the fat body and ovary contain VG messenger RNAs and syn¬ thesize and secrete all three corresponding yolk polypeptides (Huybrechts et al., 1983). By contrast, none of the three VG polypeptides synthesized and secreted by the fat body of Calliphora erythrocephala appear to be produced by the ovary (Fourney et al., 1982). Ovarian VG synthesis in A. domesticus may be significant in the context of ooplasmic localization of VN in the fully grown oocyte. Nicolaro and Bradley (1980) reported that the two native VNs of A. domesticus are nonrandomly distributed in the fully grown oocyte, VN II predominating in the anterior end and VN I in the posterior end of the oocyte. How these gradient-like VN distributions are established is unknown, but one possibility is that preferential uptake of the corre¬ sponding VGs occurs at opposite poles of VG follicles. Vitellogenin synthesis of each VG within developing follicles could also contribute to the final VN distribution in the oocyte. The existence of two high molecular weight, VG precursor polypeptides in A. domesticus was predicted by Harnish and White (1982) who have proposed an evolutionary model for insect VNs based on the number and size of the processed VG polypeptides in insects representing eight orders. In A. domesticus four VG polypeptides are resolved in denaturing poly¬ acrylamide gels (Bradley and Edwards, 1978). The molecular weight for two of these is about 100 kDa and for the other two is about 50 kDa. According to the model of Harnish and White (1982) , these large (> 100 98 kDa) and small (50 kDa) VG polypeptides are derived from larger (approx. 200 kDa) precursor polypeptides by proteolytic processing, each precursor yielding a large and a small VG polypeptide. A precursor-product relationship between the high molecular weight female-specific fat body polypeptides reported here and the four hemolymph VG polypeptides in A. domesticus (Bradley and Edwards, 1978) has been established, and the relationship between each precursor and its proteolytic products is being investigated.

Wayne Lacy Department of Economics Auburn University at Montgomery Montgomery , AL 36193 I. Introduction This paper examines the long term trend of income distribution in Alabama and compares it with that of the U.S. in general. A widespread impression is growing that income is once again becoming more unequally distributed in the United States, after many years of movement toward more equality. Although most references in the news tend to talk about changes in the 1980s, the reversal in the trend toward equality began much earlier for the U.S. as a whole. This paper examines the data available for Ala¬ bama from the Census of 1960, 1970, and 1980 to see if the state differs from the U.S. and to what degree. The basic measure of income used in this study is earned income. It is not adjusted for any income transfers received or for taxes paid; nor is it adjusted for differences in the income life cycle of the population. The life cycle considers the age structure of the population and the relative differences in earnings expected at different ages in the life span of individuals. This was not treated in this paper, although some mention will be made of the factors that possibly affect the degree of equality of income. II. Lorenz Curves and Gini Concentration Ratios The most widely used measure of income distribution is the Lorenz Curve and the Gini Concentration coefficient or rate derived from that curve. In Figure 1, the 45° line OA shows the line of equal distribution of income where 1 percent of the units have 1 percent of the income , 5 percent have 5 percent, and so on. The curved line OXA is the Lorenz curve showing the actual distribution of income. The gini coefficient is measured by comparing the shaded area OAX to the triangle OAB . That is: Gini - Area OAX Area OAB Thus, as area OAX approaches 0, gini approaches 0, a perfectly equal income distribution. As the gini coefficient grows larger (maximum value of 1) income grows more unequal. The gini formula used for computation was: k G “ 1 i ? i (fi+1 -fi) (Yt +Yi .,) Manuscript received 11 April 1988; accepted 10 March 1989 101 Lacy FIGURE 1 O where the ft represent the cumulative percent of total units (families or households in this study) at points measured on a Lorenz curve, and the Yt represent the respective cumulative percent of aggregate income for those units [ Bronfenbrenner , p. 221]. Great care should be taken in the use and interpretation of gini coefficients. Bronfenbrenner [1971, pp. 49-50] points out several problems exhibited by the measure. First, the measure's sensitivity to change is low as compared to the possibility of sampling error. Simply stated, this means that differences in measures that are close together could be of no significance and sampling error could easily have resulted in the respective placements. This holds for any reasonably close values. Secondly, the gini coefficient does not recognize any differences between the locations of the points used in the income distribution data. For example, it is quite possible to have the same gini coefficient for very different types of income distributions. This can be seen in Figure 2. In Figure 2, the two Lorenz curves OABC and ODEC would have the same gini coefficient if the area bounded by OAXDO were the same as the area bounded by XECBX. Yet a humanitarian argument might well be made that OABC is more "equitable" if not more equal distribution of income than 102 Income Distribution in Alabama FIGURE 2 O ODEC since there is a smaller percent who would fall into the poor cate¬ gory. However, this also implies that while a smaller percent would be very rich, they would be much richer than in the ODEC case. A third concern arises because the fewer the number of points availa¬ ble for analysis on the Lorenz curve, the stronger a bias exists in computing the gini coefficient as too low. The more points, the better the estimate. These considerations raise some concern over the interpretation of the results of this study. The gini coefficient ratios computed or used herein are not strictly comparable since they are computed from different Censuses with differing number of income groups and different cumulative levels of income. As such they must be treated only as general indicators for fairly large changes in values. Extreme caution must be used in their interpretation . III. Income Distribution in the U.S. An examination of the index of income concentration presented in the Current Population Reports indicates that since World War II the United 103 Lacy States has gone through two phases - one in which the distribution of income trended towards greater equality (from 1950 until the later 1960's) and another in which a reversal of the trend toward equality has taken place (from the late 1960 's to the present). This can be seen in Table 1. In 1947 the gini coefficient of income distribution for the U.S. (for families and unrelated individuals) was .376. From that time until 1967- 68 the distribution of income in the U.S. tended to become more equal, as indicated by the gini decrease to .348. Since then, the trend has re¬ versed with the gini rising to .365 in 1980 and accelerating since then to .389 in 1985. Thus the distribution of income in 1985 was more unequal than it was in 1947. Table 1. U.S. Gini Coefficients for Selected Years (Families and Unrelated Individuals) . Year Gini 1947 .376 1950 .379 1955 .363 1960 .364 1965 .356 1967 .348 1968 .348 1970 .354 1975 .358 1980 .365 1984 .383 1985 .389 SOURCE: Current Population Reports, Series p. 60 "Consumer Income" Especially interesting to note is that the reversal of the trend toward income equality in the U.S. began at the very time when the growth of social programs were at their height. The turning point coincides roughly with the beginnings of Lyndon Johnson's "Great Society" program, which was supposed to reduce the inequality of income. It would be hasty to assume that the growth of welfare programs contributed to income in¬ equality, although such arguments might be made. Other factors, such as the enormous growth of the labor force in the late 1960 's and 1970' s, that strongly influenced the age composition of the work force, could be a more pertinent factor, as could changes in the tax structure of the economy over time . 104 Income Distribution in Alabama Alabama Income Distribution Typically, the income distribution of Alabama families has been characterized as among the most unequal of the states in the U.S. A study by Al-Samarrie and Miller (1967) ranked the state 47th out of 50 in 1949 and tied for 45th in 1959. The movement from 47th to 45th was accompanied by a significant increase in equality as the gini coefficient fell from .475 in 1949 to .424 in 1959, as compared to a national drop from .405 to .371. A later study by Sale (1974), showed Alabama ranked 47th of the 48 conterminous states in 1949 and 45th in 1959 with his gini calculations dropping from .4778 to .4390 over the same period. From 1959 to 1969, however, Sale's study shows Alabama slipping to 46th place, even though the gini continued to fall to .3983 over the period. Thus it would appear that great progress in equalizing income occurred in Alabama, as well as the rest of the U.S. in the two decades prior to 1970. To present a picture of the movement in income distribution, Figure 3 was constructed showing the Lorenz curve for Alabama families for the years 1959, 1969, and 1979 based on the data from the 1960, 1970 and, 1980 Censuses . O FIGURE 3. Actual Alabama Lorenz Curves. 105 Lacy The movement toward more equality over the decade of the 60 's can be clearly seen as the Lorenz curve shifted left toward the line of equal distribution. However, the curve for 1979 almost overlaps that of 1969, showing only a minute shift towards more equality. Thus the long term trend towards a more equal distribution of income in Alabama slowed almost to a halt in the 1970' s. As will be shown below, these results will be borne out by the Gini coefficients. The data for the Lorenz curve are presented in Appendix Tables A, B, and C. The question remains as to how different areas of the state fared during this period and how they compared to the state overall. To answer these questions, data from the three past Censuses were utilized to examine the income distribution of families in the SMSA's of Alabama for which data is available for those years. The results are shown in Table 2. The 1969 ginis were published directly in the 1970 Census. However, that was the only Census to pre-calculate these data. The 1979 ginis were calculated by the author using the income data of the 1980 Census and the formula given above . Unfortunately, for the purposes of this study neither the mean family incomes nor the total family incomes for SMSA's were available in the 1960 census data. All that is given is the total number of families. The distribution of income is given but the final category of $25,000 and over is open ended, thus the total family income needed to compute the gini coefficient is not available. To get around this problem a method was devised to estimate the total and also mean family incomes for the SMSA's in Alabama for 1960. This was Table 2.

Census Data. 106 Income Distribution in Alabama achieved by taking the total income for the SMSA, dividing it by the pop¬ ulation to get per capita income for the SMSA. This was then multiplied by 3.91, the figure for the average number of persons per family in the State of Alabama (the number of persons per family was not given for SMSA's). Table 3 shows the relationship between the estimated mean family income and the stated median family incomes of the Census. As can be seen, they follow the pattern usually exhibited in such a relationship, that is , the means exceed the medians . Table 3. Comparison of Actual Median Family Income To Estimated Mean Family Income for Alabama SMSA's, 1954. ALABAMA SMSA ESTIMATED MEAN FAMILY INCOME (1) ACTUAL MEDIAN FAMILY INCOME (2) RATIO (1) (2 Birmingham $6125 $5103 1.20 Gadsden 5201 4387 1.19 Huntsville 5794 5426 1.07 Mobile 5797 5132 1.13 Montgomery 5755 4777 1.20 Tuscaloosa 4912 4274 1.15 SOURCE: 1960 Census of Population, and calculations therefore. Although these figures seem reasonable, they make the computed SMSA ginis for 1960 somewhat more suspect and should be used only as approxi¬ mations. Because of the very small number of families in the upper income category of $25,000 and over, the estimate should be reasonably close however. Birmingham had the largest percent in this group, a small 1.3 percent, followed by Montgomery (1.2 percent), Tuscaloosa and Mobile (0.8 percent), Huntsville (0.6 percent), and Gadsden (0.4 percent). With these considerations in mind, the computed ginis for 1959 should be reasonably reliable. For 1959 Huntsville had the most equal distribu¬ tion of income, followed by Mobile, with Montgomery having the most unequal distribution, but closely followed by Gadsden, Birmingham, and Tuscaloosa. All of the metropolitan areas had more equal incomes than the state as a whole. This means that the income distribution between metro¬ politan areas and non-metropolitan areas must have been even more unequal. From 1959 to 1969, Alabama followed the national trend toward more equality of income, although gains in this decade were modest in most of the SMSA's. Gadsden made the largest gains in the decade and significant gains were made by Birmingham. Mobile made a significant shift away from equality and Tuscaloosa possibly made a minor move toward inequality. 107 Lacy Montgomery made a small move toward equality while Huntsville's move in that direction was minute. With the growth of these six SMSA's, the disparities of income rela¬ tive to the state as a whole grew. Mobile, Montgomery, and Tuscaloosa had income distributions that were more unequal than the state average while Birmingham, Gadsden, and Huntsville had more equal distribution than the state average. From 1969 to 1979, the distribution of income in the state became only slightly more equal. In 1979 the state ranked 46th of the 50 states in income equality, ahead of only Mississippi, Louisiana, Arkansas, and Florida, but just behind several other southern states [Lacy, 1988], Nevertheless, Alabama did considerably better than the U.S. as a whole as can be seen in Table 1. Nationally, income became more unequal. By 1979, there was much less disparity of income distribution within the SMSA's than in the previous two decades. Huntsville, Gadsden, and Birmingham, the three SMSA's with the most equal income distribution in 1969, all followed the national trend toward more inequality. Tuscaloosa, Montgomery, and Mobile, the three SMSA's with the most unequal incomes in 1969 did not follow the national trend and moved towards a more equal distribution of income. Consequently the range of ginis of the six SMSA's was only .079 from .3763 to .3842. All of the SMSA's had ginis lower, but not far removed from, the state average. Thus over the twenty year period, the state of Alabama saw a consider- ble movement towards a more equal distribution of income. Although the movement slowed during the decade of the 1970' s, the progress made is not altogether insignificant when viewed in the context of the national trend to greater inequality. The question remains as to what has happened since 1979. Using the national figures of Table 1, the trend for greater in¬ equality has not only continued but has accelerated. Whether Alabama has been able to move against this trend will not be known until data from the 1990 census becomes available. LITERATURE CITED Al-Samarrie, A. and Miller, H.P. 1967.

Holley L. Handley, Barbara Esteridge and James T. Bradley, Auburn University, AL 36849. Insect vitellogenins are multisubunit phospholipoglycoproteins presumed to serve as a source of nutrients during embryogenesis . The mechanisms whereby these molecules are metabolized by the developing egg are poorely understood. Two monoclonal antibodies have been produced with specificity for two of the cricket vitellogins, one MAb (2D-1) having specificity for only one of the yolk polypeptiedes (YP-2b) , and the other MAb (IE-10) having specificity for two of the polypeptides (YP-1 and YP-2b) . The antibodies were screened by a Bio-Dot assay (Bio-Rad) and the selected positive cell lines cloned twice. The specificity was determined using Western Blotting. The subclass of immunoglobulin was determined to be IgG by agar gel immodif fusion. The antibodies were shown to react in different locations in the egg by the immunohistochemical staining using avidine-biotin horseradish peroxidase system. Further studies using Western Blotting have shown that the antibodies react with different degradation products which form during embryogenesis. These studies support the idea that the degradation of vitellogenins during embryogenesis results in smaller peptide fragments derived directly from the original vitellin present in the egg. By producing a family of monoclonal antibodies specific for different degradation products, a precursor-product relationship can be established. This information can then be used to determine the developmental/ physiological significance of vitellin and the role the embryo's genome might play in their utilization. (Supported by the Al.

Grown for 5 weeks at 23°C there was a range in colony diameter from 13.5 mm to 36.5 mm. Dry wt. of mycelium varied from .Q45g to . 124g per colony. Sporulation ranged from profuse to very little. Some colonies were mounded; others were spread. Polyacrylamide gel electrophoresis showed differences between isolates. Ill Abstracts REDISTRIBUTION OF A ZONA PELLUCIDA BINDING COMPONENT ON MURINE SPERM. Donna A. Free, Holly Boettger, Teresa Battle, and Gary R. Poirier, Dept, of Biology, Univ. of Ala., Birmingham, AL 35294. The exposure and distribution of an epitope of a 15,000 molecular weight component on the head of murine spermatozoa was monitored with a monoclonal antibody during in vitro incubation. The component, termed the acceptor, binds a proteinase inhibitor of seminal vesicle origin at ejaculation and functions in zona binding (Irwin, et al., 1983; Poirier et al., 1986). The epitope is not visible on undiluted cauda epididymal sperm, but can be localized on the plasma membrane over the acrosomal cap region on 70 to 100 percent of washed sperm. In some samples approximately 10 percent of the sperm express the epitope in the equatorial region of the sperm head. With incubation at 37° for 90 minutes, the percentage of sperm with equatorial expression increased to 70 percent while the percentage with exclusively acro¬ somal cap expression decreased to 10 percent. These changes are temperature dependent but not medium or Ca++ dependent. They will occur in the presence of metabolic poisons. Prelabeling the epitope with the monoclonal antibody has no effect on the changing patterns. Pre-labeling, followed by washing at room temperature, results in a 30 percent increase in equatorial expression. The seminal inhibitor binds only in the acrosomal cap region of incubated sperm. Acrosomal cap and equatorial expression can be detected on sperm retrieved from the uterus after natural insemination. The data suggest that the epitope is first visible with dilutions of the epididymal fluids. The second step, exposure in the equatorial region, is due to a tempera¬ ture sensitive step which may involve an unmasking and/or a migration. TAXONOMIC POTENTIAL OF PALATAL SENSILLA OF BITING MIDGE LARVAE (DIPTERA: CERATOPOGONIDAE). Lawrence J. Hribar, C. Steven Murphree, and Gary R. Mullen, Department of Entomology, Auburn University, AL, 36849-5413. The sensilla located on the labral palatum have been neglected as taxonomic characters for biting midge larvae. Studies of larvae of 2 Dasyhelea spp., 4 Culicoides spp., and 6 Bezzia spp. have revealed that the number, position, and relative size of sensilla vary among the taxa examined. Dasyhel ea sp. A: 6 pairs; 2 flat, round; 3 seti- form; 1 trifurcate. Dasyhelea sp. B: 7 pairs; 4 flat, round; 2 seti- form; 1 trifurcate. Culicoides travisi: 6 pairs; 2 flat; 4 elongate. Culicoides melleus: 6 pairs; 5 round; 1 setiform. Culicoides obsoletus: 5 pairs; 4 round; 1 setiform. Culicoides sanquisuga: 10 pairs; 5 elongate; 5 rounded. Bezzia bivittata: 5 pairs; 4 setiform; 1 round. Bezzia nobilis: 7 pairs; 3 elongate; 4 round. Bezzia sp. A: 7 pairs; 4 round; 3 elongate. Bezzia sp. B: 4 pairs; 3 round; 1 ovoid. Bezzia sp. C: 5 pairs; 4 round; 1 elongate. Bezzia sp. D: 7 pairs; 3 elongate; 4 round. The results of this study indicate that the sensilla on the palatum can be used as a taxonomic character among the taxa examined. Further study is required to determine whether this is true for the Ceratopogonidae as a whole. 112 Abstracts INDUCTION OF ORNITHINE DECARBOXYLASE AND POLYAMINE SYNTHESIS IN EMBRYOS OF THE BRINE SHRIMP Ar temia spp. Stephen A. Watts and George B. Cline, Dept, of Biology, Univ. of Ala. at Birmingham, Birmingham, AL 35294. Reproductively active Artemia respond to environmental stress by encysting their embryos. These cysts are able to survive long-term dehydration but will begin to develop when rehydrated in >5 ppt sea water. Specific mechanisms regulating intracyst (gastrula) development are of considerable interest since it is not known what signals initiate metabolic and synthetic pathways after rehydration begins. We examined both dehydrated and rehydrated cysts (20 ppt seawater, 28°C) during development for ornithine decarboxylase (ODC) activity and polyamine production, important regulators (indicators) of embryonic development in vertebrate systems. We found significant levels of ODC activity in dehydrated cysts (3.34 nmol/hr/g wet weight) . These residual levels decreased within one hour of hydration but then increased significantly within 2 hours, suggesting de novo synthesis of protein. Activity increased to 164 nmol/hr/g wet weight within 7 hours of hydration. Putrescine, spermidine and spermine levels increased rapidly during the first 4 hours of rehydration with highest levels (1.35, 1.34 and 0.06 uM/ g wet weight, respectively) observed after 12 hours. Spermidine/ spermine ratios reached 20 , reflecting high rates of biosynthetic activity. Polyamine levels decreased prior to hatching at 18 hours. Significant levels of characteristically labile ODC are apparently stored/stabilized in dehydrated cysts over long periods and are available to initiate development with rehydration. Apparent 5 , reflecting higher rates of protein synthesis during cell growth and proliferation. These data suggest that the levels and distributions of polyamines may reflect distinct ecological and physiological differences among species and functional differences among tissue types. DISTRIBUTION OF GLYCOLYTIC ENZYMES IN THE SEA STAR ASTERIAS VULGARIS . Naoyuki Saito and Stephen A. Watts, Dept, of Biology, U.A.B., Birmingham, AL 35294. The specific activities of hexokinase (HK), phosphof ructokinase (PFK) and pyruvate kinase (PK) were determined in the pyloric caeca, tube feet and body wall of Asterias vulgaris . Specific activities were expressed as functions of wet 'weight and cytosolic protein. The average gravimetric distribution of the organs were calculated (wet organ weight/wet animal weight: pyloric caeca 16%; tube feet 3%; body wall 55%) to determine the total enzyme activities per organ. HK and PK activities were significantly higher than PFK activity in all organs studied. The highest HK activity as a function of wet weight was found in the pyloric caeca. Despite low PFK activity, the highest PK activity per gram wet weight as well as the highest total PK activity were found in the pyloric caeca. These results suggest that a high concentration of a glycolytic intermediate, probably glyceraldehyde-3-phosphate derived through lipid catabolism, enters the pathway after PFK. Tube feet exhibited the highest PFK and PK activities as a function of cytosolic protein. This may reflect the high energetic requirements of the tube feet. As a function of wet weight, activities of HK, PFK and PK were minimal in the body wall, reflecting low organic content of the organ. However, the highest total PFK activity and highest HK activity per mg cytosolic protein suggest the importance of the body wall in the overall glycolytic activity of the organism. 123 Abstracts PRODUCTION AND CHARACTERIZATION OF MONOCLONAL ANTIBODIES SPECIFIC FOR CILIARY MEMBRANES OF TETRAHYMENA PYRIFORMIS. Barbara H. Estridge and Christine A. Sundermann, Department of Zoology and Wildlife Sciences, Auburn University, AL 36849. Tetrahymena pyrif ormis (ATCC 30005) were deciliated and ciliary membranes were purified by sucrose-gradient ultracentrifugation. Balb/c mice were immunized with purified ciliary membranes and monoclonal antibodies (MAb) to ciliary membranes were generated by fusion of X63-Ag8 . 653 cells with immunized Balb/c spleen cells. Fused cells were cultured in 96-well plates, and supernatants were tested for antibody by enzyme immunoassay, using whole cilia as antigen and alkaline- phosphatase labeled secondary antibody (anti-mouse IgG, anti-mouse IgM). Cells from antibody-positive wells were cloned or frozen, and super¬ natants were retained. Thirteen MAb (7 IgG, 6 IgM) have been tested by indirect immunofluorescence and immunoperoxidase staining. Five staining patterns were observed: 1) intense staining of cell body and cilia, 2) patchy staining of cell body and cilia, 3) intense staining of cilia but not cell body, 4) moderate staining of cell body with cilia unstained or weakly stained, and 5) moderate staining of cell body and cilia. Some MAb stained the Tetrahymena culture heterogeneous¬ ly. The culture was cloned to separate positive and negative staining subpopulations, and clones were tested repeatedly by immunoperoxidase staining. The variations in staining patterns suggest that 1) some determinants are present only on cilia or cell body, while others are present on both cell body and cilia, and 2) the culture contains two antigenic types, distinguishable by immunoperoxidase staining.

NON-SPECIFIC HYPERPLASTIC RESPONSE IN L-M CELLS INDUCED BY VACCINIA VIRUS Lawrence Drummond* and Lyman Magee. *Biology Dept, Talladega College, Talladega, AL 35160. Dept. Biology, Liberal Arts, University of Mississippi, University, MS 38677 L-M mouse fibroblast cells propagated in Yeast Extract Lactalbumin Hydrolysate Peptone (YELP) medium. Mediun-199 or Eagle's minimal esential medium with or without fetal calf serum were infected with 5, 10, and 20 plaque-forming units (PFU) of vaccinia virus per culture. The cultures were examined microscopically daily. Areas of focal pro¬ liferation were observed in cultures propagated in YELP medium and Medium-199 supplemented with 3% fetal calf serum and infected with 5 to 20 PFU/culture 48-72 hours post-infection. There was a significant increase in the total protein concentration per culture infected with 5, 10, and 20 PFU per culture demonstrating focal pro¬ liferation, Electron microscopy of thin sections of areas of focal proliferation revealed intracellular localization of vaccinia virus in all sections examined. These re¬ sults indicate that a virus-cellular interaction is involv¬ ed in the cellular proliferative response in L-M cells infected with varying PFU/culture of vaccinia virus. 124 Abstracts EIMERIA PAPILLATA (PROTOZOA: AP i COMP LEX A) : EARLY DEVELOPMENT IN VIVO AND IN VITRO, Stephanie A. Stafford and Christine A. Sundermann, Dept. Zoology and Wildlife Science, Auburn University, AL 36849. The early development of Eimeria papillate in the mouse has not yet been described. Thus, the purpose of this study was to investigate early merogony and determine if spherical meronts (common to most eime- rians) or sporozoite-shaped meronts (multinucleate forms that retain the shape of a sporozoite) are produced. Mice were inoculated orally with 6 million oocysts of JL papillata and killed 30 hours later. Por¬ tions of the small intestine were excised, and mucosal scrapings from each animal were examined with Nomarski interference contrast micro¬ scopy (NIC). Motile sporozoite-shaped meronts were observed entering and leaving host cells and contained one large posterior refractile body and one small anterior refractile body and several nuclei. Twenty living specimens were measured, and the mean length and width were 1 1 . 98um and 3. 73um respectively. Stained slides revealed that the mer¬ onts were indeed multinucleate. In order to isolate and concentrate these meronts for further study, the small intestine was minced, placed in a solution of bile and trypsin at 37C and then column-filtered. The filtrate was centrifuged and the resulting pellet examined by NIC. Numerous sporozoite-shaped meronts were observed; they displayed for¬ ward motility and the bending and flexing movements often associated with excysted sporozoites. The isolated meronts will be inoculated on¬ to human fetal lung cells (passage 15) and primary fetal mouse brain cells to observe, in vitro, early merogony of JL papillata. The obser¬ vation of sporozoite-shaped meronts in the early development of JL pap¬ illata serves as a valuable laboratory model for further studies of the early developmental stages of similar coccidia. EVOLUTIONARY AND DEVELOPMENTAL IMPLICATIONS OF THE STRUCTURE OF ACETYLCHOLINESTERASE FROM THE LAMPREY PETROMYZON MARINES . Leo Pezzementi, Birmingham, Southern College, Birmingham, Alabama 35254 In the skeletal muscle of higher vertebrates, acetylcholines¬ terase (AChE) has been found to exist in globular forms, , G^. and , consisting of one, two or four catalytic subunits; and asyxmnetic forms, A^, Ag, and Aj^, consisting of one, two or three globular tetramers linked to a collagenous tail. In contrast, only globular forms of AChE have been reported in deuterostome invertebrates. To obtain information about the evolution of AChE, we studied the enzyme from the lamprey Petromyzon marinus , a member of the most primitive class of vertebrates, the Agnatha. Sequential extraction of enzyme and velocity sedimentation on sucrose gradients indicated that muscle from adult spawning lamprey contains G^, A^, Ag, and Aj2 AChE. We confirmed the presence of asymmetric AChE by collagenase digestion and low-salt precipitation. Thus, muscle from representatives of all classes of vertebrates has asymmetric and globular AChE, possibly be¬ cause asymmetric forms are needed at the neuromus clular junction for rapid and coordinated muscle contraction. We also found that the muscle of the larval form of the lamprey, the ammoeoete, possesses asymmetric and globular AChE. In contrast to adult spawning lamprey, where globular esterase is almost all , ammoeoete muscle contains significant amounts of and G2 . The absence of these globular forms in the spawning lamprey may be due to the degenerative state of the lamprey in this stage of its life cycle. 125 Abstracts STEROID METABOLISM IN SOMATIC AND GAMETIC TISSUES OF THE SEA STAR ASTERIAS VULGARIS. Gene A. Hines and Stephen A. Watts, Dept, of Biology, U.A.B., Birmingham, AL 35294, Charles W. Walker, Univ. of New Hampshire, Durham, NH 03824, Peter A. Voogt, State University, Utretch, The Netherlands. Supported by NSF #DCB-871 1425. Tissues were obtained in the fall during early stages of gametogenesis when gonads and, presumably, somatic tissues are metabolically active. Microsomal preparations of male and female pyloric caeca, body wall, testis and ovary were incubated with radioactive androstenedione to evaluate androgen and estrogen metabolic pathways. Testis, ovary, and body wall homogenates were incubated for eight hours; pyloric caecal homogenates were incubated for two hours. Product identification was determined via TLC and recrystallization to constant specific activity. Androstenedione was converted primarily to testosterone and also to androstanedione and epiandrosterone in all homogenates, indicating high 1 7(3- hydroxys teroid dehydrogenase (HSD) activity relative to 5a-reductase ana 3J3-HSD. Trace levels of unidentified products were found which may represent other androstane derivatives, steroid esters, or degradation products. Highest rates of androstenedione conversion were found in the pyloric caeca. It is not known whether high levels of androgen metabolism in the pyloric caeca are related to cholesterol catabolism associated with digestion, or production of metabolically active steroids. 5a-androstane-3|3,17j3-diol, a potent androgen, was produced in male and female pyloric caeca. Homogenates of male and female body wall showed relatively low rates of androstenedione conversion. Homogenates of testes and ovaries produced the highest levels of androstanedione and epianairosterone relative to somatic tissues. In gonadal tissues, highest rates of androstenedione conversion were found in the testes. No estrogens were detected by TLC, however, preliminary RIA has detected significant levels of estradiol in male and female gonads and pyloric caeca with highest levels noted in ovaries. Sex-specific differences in androgen metabolism were most apparent in gonadal tissues; these differences were not apparent in somatic tissue. ACTIN AND MYOSIN GENE EXPRESSION IN CHICK CARDIAC CELL CULTURES. Ronald £. Young . Lee L. Zwanziger and Debra M. Moriarity. Department of Biological Sciences, Univ. of Alabama, Huntsville, AL 35899 Cells from the ventricles of thirteen-day chick embryos were cultured for 1, 4, 8, and 12 days in a serum-free, chemically defined culture medium. The quantity of total protein per cell increased approximately three-fold with time in culture compared to the level in intact ventricles, whereas the quantity of myosin heavy chain per cell decreased approximately four-fold. The quantity of myosin heavy chain mRNA also decreased during the 12-day culture period. Changes in expression of the alpha, beta and gamma isoforms of actin were also investigated. The sarcomeric alpha-actin isoform predominated in homogenates of intact ventricular tissue, but the ratio of alpha-actin to beta- and gamma-actins decreased with time after the cells were placed in culture. Because avian ventricular cells do not undergo gene switching to different isoforms of sarcomeric myosin heavy chain or actin when placed in culture, these results show that cardiac cells quantitatively readjust the levels of individual contractile proteins downward by several-fold in response to the serum-free, chemically defined conditions in the cell culture environment. This culture system therefore provides an assay for quantitative effects -of exogenous pharmacological agents on the synthesis or degradation of individual cardiac sarcomeric proteins or their mRNA's, without concern for effects on gene switching.

Bryan, Dept, of Zoology & Wildlife Sciences, Auburn University, Auburn, AL 36849. Dr. Craig Guyer, Research Advisor, Dept, of Zoology and Wildlife Sciences, Auburn University, Auburn, AL 36849. Establishment of the Black Creek Seed Orchard in DeSoto National Forest, Mississippi, began in June 1988 with the clearcutting of approximately 300 acres. A two-year study was contracted by the US Forest Service to determine the effects this seed orchard establish¬ ment had on gopher tortoises (Gopherus polyphemus) . Several strict rules governed the cut, including a 3 m buffer zone around each tor¬ toise burrow, in hopes of reducing the impact on the tortoises. We present preliminary data regarding population structure, movement, and activity. Data from the seed orchard site are compared with sim¬ ilar data from an unaltered control site. The two populations closely match in mean body size, with only a 1 cm difference in male carapace length (n=15 for the study site, n=ll on the control) and no difference in carapace length for females (n=19 for study site, n=6 on control). The relative numbers of active versus inactive burrows on the seed orchard site did not differ from numbers recorded prior to the clear- cut. This indicates that the tortoises have remained on the study site. Daily use of active burrows on the two sites was not signifi¬ cantly different. Ten hatchlings were found on both the control and study sites showing the two populations to be reproductive. This study is funded by USFS contract 53-44-7U-8-4372 . THE BIOCHEMICAL AND ENERGETIC COMPOSITION OF BLADES, STIPES AND PNEUMATOCYSTS OF LIVING AND DECOMPOSING SARGASSUM FLUITANS FROM THE GULF OF MEXICO. Michael J. Lares and James B. McClintock, Dept, of Biology, Univ. of Alabama at Birmingham, Birmingham, AL 35294. The biochemical composition of individual components of Saraassum fluitans was variable, with stipes having more soluble and insoluble carbohydrate and ash than blades. Pneumatocysts were similar in composition to stipes, but had higher levels of insoluble carbohydrate than blades. Decomposing pneumatocysts had greater levels of ash than either decomposing stipes or blades, and less insoluble carbohydrate than decomposing stipes. Although there were differences in the qualitative composition of living and decomposing plant components, there were no significant differences in the overall energy contents of living and decomposing plant components (mean kJ/g dry wt of all plant components ranged from 13.4 to 14.6). A representative plant weighing 13 g wet wt would contain a total of 22.6 kJ, allocating 13.7, 6.0 and 2.9 kJ to blades, stipes and pneumatocysts, respectively. The retention of energy within tissues throughout the decomposition process is important, as this abundant pelagic species is widely distributed and may provide a significant amount of imported energy to shallow and deep sea benthic communities. 127 Abstracts TRIALS OF SEVERAL DRUGS FOR THE CONTROL OF COCCIDIOSIS IN GOATS. John C. Frandsen, USDA, ARS, Animal Parasite Research Laboratory, Auburn, AL 36831-0952. Byron L. Blagburn, Dept. Pathobiology , College of Veterinary Medicine, Auburn University, AL 36849. Goats in the Southeast harbor infections by several species of coccidia, especially Eimeria arloingi , E. christenseni and E. Parva, almost continuously throughout most of their lives. Though these infections rarely produce clinical disease in adult goats, they are responsible for morbidity and mortality in young kids, skeletal weak¬ ness in goats of breeding age, and unevaluated losses of productivity in both juveniles and adults. Control or elimination of these in- fectons by drugs is hampered by a paucity of chemotherapeutics cleared for use in goats and by the low efficacy of those that are cleared. Trials of monensin (Rumensin(R) ) , amprolium (Corrid(R)), decoquinate (Deccox(TM) ) , sulf aquinoxaline (Sulfa-Q(R) ) , clindamycin (Antirobe (R) ) , and Tribrissen (R) , a mixture of 1 part trimethoprim with 5 parts of sulfadiazine, have shown a general lack of significant efficacy in re¬ ducing fecal oocyst production over a period of time, indicating that the use of these drugs as a means for reducing the exposure of young kids to infection is of limited - if any - value. Recently, trials with toltrazuril (Bay Vi 9142, Baycox(R)), a triazinetrione synthe¬ sized as a coccidiostat for broilers, have indicated that this drug has promise and warrants further evaluation. Administered either as a drench or in drinking water, at 15 ppm for 14 days, it leads to a reduction in oocyst production. ALTERED CRICKET FAT BODY PROTEIN METABOLISM AFTER OVARIECTOMY. James T. Bradley, Patrizio Caturegli and Barbara Estridge, Dept, of Zoology and Wildlife Science, Auburn University, AL 36849. Vitellogenesis in Acheta domestious begins with induction of vitellogenin (VG) synthesis soon after ecdysis to the adult. Pre-VGs are synthesized and processed in the fat body, secreted into the hemo lymph, and sequestered by vitellogenic follicles. Pre-VG processing includes glycosylation , phosphorylation, and specific proteolytic cleavages. Ovariectomy before adult ecdysis effects neither the timing of later VG induction nor the rate of fat body VG synthesis, but the rate of secretion of newly made VG is attenuated after ovariectomy. This phenomenon is being exploited to gain insight into regulation of protein secretion in eukaryotic cells. Fat body proteins were labeled in vivo with [ 35S ] -methionine at various times after ovariectomy or sham operations, separated by SDS-PAGE, and analyzed by fluorography and Western blotting. Ovariectomy resulted in changes in the pattern of incorporation of label into fat body polypeptides, and electron microscopy revealed an above normal accumulation of secretory vesicles in fat body cell cytoplasm. Immunological approaches are being used to learn how ovariectomy-induced alterations in fat body protein metabolism are related to steps in pre-VG processing.

George W. Folkerts. Dept, of Zoology and Wildlife Science, Auburn Univ. , AL 36849-5414 Pitcher plant habitats have been largely neglected by ecologists because they are not traditional wetlands, nor are they typical terrestrial habitats. This, along with the fact that fire restriction has allowed successional changes to essentially obliterate many sites, has resulted in a lack of appreciation of their uniqueness. The flora of pitcher plant habitats is unique in a number of its characteristics. In life form, essentially all species are perennial herbaceous geophytes. Almost none of the species are shade tolerant. All are fire tolerant, mainly as a result of their geophytic habit. The community is conspicuously microspermous, nearly 60 percent of the species having diaspores less than 2mm in length. The dispersal spectrum differs conspicuously from that of adjacent communities, an unusually high percentage of the species having rainwash hydrochory as their primary dispersal method. Sedges (Cyperaceae) comprise approximately 20 percent of the flora. Many of the species are highly lignified, a feature which may relate to their flammability, their low nutrient content, and the relatively low incidence of herbivore damage. These characteristics, along with the high diversity of carnivorous plants, indicate that the flora of pitcher plant habitats possesses unique features which make it, as an abstract unit, as distinct as any other plant community on the Coastal Plain of southeastern North America. STATUS OF ALABAMA BIRDS AND MAMMALS. Dan C. Holliman, Division of Science and Mathematics, Birmingham-Southern College, Birmingham, Alabama 35254 The status of those birds and mammals listed in Vertebrate Animals of Alabama in Need of Special Attention (Al. Agri. Exp. St. Auburn, University, Auburn, Al, 1986) is reviewed. Status changes and data gaps are detailed for other birds and mammals that were not included in the proceedings of the 1983 Alabama First Nongame Wildlife Conference. Critical habitats and stress sources are described. A research and management program along with specific jobs within these programs are listed by priority. A basic philosophy relative to the implementation of the program encourages rangewide studies, coopera¬ tion among educational institutions and the utilization of ongoing state and federal activities. 129 Abstracts INVESTIGATION OF THE CARYOCYST OF CARYOSPORA BIGENETICA (APICOMPLEXA: EIMERIIDAE) . Christine A. Sundermann, Dept. Zoology & Wildlife Science, Auburn University, AL 36849. David S. Lindsay, USDA, Beltsville, MD, 20705. Caryospora bigenetica is a coccidian with a heteroxenous life cycle involving viperine snakes and rodents. When rodents are experimentally infected with snake-derived oocysts, asexual and sexual reproduction occur in a variety of extraintestinal sites. Sporulated oocysts in the tissues release motile sporozoites that then enter other host cells. The final developmental stage is the formation of caryocysts - host cells, containing a sporozoite (s) , that round-up and become enclosed by a thick wall. In this study, a male cotton rat was inoculated with snake-derived oocysts and then sacrificed 16 days later (DPI). Portions of the scrotum, footpad, and muzzle were processed for histological and electron microscopical (TEM) observation. TEM revealed that the sporo¬ zoite had an anterior and posterior refractile body, centrally-located nucleus, posterior pore, micronemes, rhoptries, a conoid, a micropore at the level of the anterior refractile body, amylopectin granules, and lipid bodies. Also present were a Golgi body, a mitochondrion, and 24 subpellicular microtubules. The infected host cell was spherical and surrounded by a fibrous wall-like covering that was 0.35 - 1.00 um thick and PAS-positive . It is not known if this wall forms by secretory ac¬ tivity of the host cell or is built by incorporation of material from the extracellular matrix. To test longevity of the caryocysts, mice were inoculated with sporulated oocysts; all animals developed clinical signs of dermal coccidiosis 8-12 DPI and then recovered. The mice were sacrificed more than a year later, and fresh tissue scrapings were treated with bile/ trypsin. The wall of the caryocyst quickly disinte¬ grated and the sporozoites became motile.

The murine zona pellucida consists of three glyco¬ proteins ZPl, ZP2 and ZP3, with molecular weights of 200,000, 120,000 and 83,000 daltons. Both ZP2 and ZP3 function in the binding of sperm to the zona. ZP3 is responsible for initial binding, while ZP2 functions to bind sperm during zona penetration (Bleil et al, 1988). This presentation demonstrates that a 15,000 MW component, the acceptor, localized on the head of murine spermatazoa binds to whole and heat solubilized zonae as well as to purified ZP2 and ZP3. These observations indicate that the acceptor may play a major role in the sperm-zona interactions which lead to fertilization. 130 Abstracts THE PHYLOGENETIC POSITION OF THE FOSSIL TELEOST FISH MICROCAPROS LIBANICUS . Steven J. Zehren, Dept, of Cell Biology and Anatomy, Univ. of Ala. at Birmingham, Birmingham, AL 35294. The Family Caproidae (boarfishes) contains two living genera, Capros (with one species, C^ aper) and Antigonia (with 11 species). A number of fossil species have also been assigned to the Caproidae including three of the genus Capros , three of the genus Antigonia and one of the genus Microcapros (M. libanicus from the Cenomanian of Lebanon). Twen¬ ty-four characters are noted in the literature as being indicative that Microcapros is a caproid. However, osteological examination of aper and seven of the living species of Antigonia reveals that only two of these characters are derived and common to all three genera (frontals ornamented with tubercles; dorsal spines alternately inclined). None of the other characters is indicative that Microcapros is a caproid because they are of questionable polarity (spines on cleithrum, supra- cleithrum and posttemporal ; dorsal spines grooved), primitive (frontals high; supraoccipital crest thornlike; lacrimal articulates with lateral ethmoid; last dorsal spines diminished in height; strong pelvic spine present) or absent in one or more of the three genera (frontals orna¬ mented with spinous ridges; infraorbitals of constant height; subocular shelf present; mouth large and oblique; ascending process of premaxilla well-developed; one supramaxilla; mandibular canal in a groove; post¬ temporal bifid; six pelvic rays; nine dorsal spines; scales not cover¬ ing bases of spinous dorsal and anal fins; presence of thickened scales in front of pelvic fins). It is concluded that Microcapros should be removed from the Caproidae and placed in the position incertae sedis . GROWTH AND DEVELOPMENT IN LARVAE OF THE SOUTHERN LEOPARD FROG (RAN A UTRICULARIA) AT CONSTANT AND FLUCTUATING TEMPERATURES. David H. Nelson, Department of Biology, Univ. of South Ala., Mobile, AL 36688. Larvae of the Southern leopard frog were reared (from eggs) for six weeks in environmental chambers at constant (10°C, 17°C, 25°C) and fluctuating (cyclic and non-cyclic) temperature regimes. Fluctuating temperatures varied from 10°C to 25°C with mean values of 17.5°C. Stages of development and body lengths were compared after three weeks. At the termination of the six-week study, the stages of development, body lengths and body weights were recorded. Among the constant temperatures (as expected) , the values for all parameters were directly related to temperature. Although the differences in some cases were slight, values for all parameters were greater at the noncyclic, fluctuating temperature regime than at the cyclic, fluctuating regime. 131 Abstracts CHEMISTRY ELECTRON DENSITY ANALYSIS OF BONDING BETWEEN INVERTED-TRICOORDINATE CARBONS. Osman F. Griner and Koop Lammertsma; Department of Chemistry, University of Alabama at Birmingham, University Station PHS-219, Birmingham, AL 35294. Rhombic dicarbides contain two inverted tricoordinate carbons at the bridge¬ head positions that are separated by a distance shorter than a typical C-C single bond. The bonding nature of rhombic dicarbides, C2X2 where X = Li, Be, B, C, and CH+, are investigated using Bader’s topological electron density approach. While the electron density for bridgehead C-C bond of C2Li2 is high, it gradually decreases for C2Be2 and C2B2. Particular empha¬ sis is given to rhombic C4 since the interpretation of stability, bonding, and spectroscopic characteristics of this species have been controversial. At the HF/6-31G* level of theory, a bond path between the inverted-tricoordinate carbons is located and the corresponding bond critical point has a close re¬ semblance to a catastrophe point. However, when the electron correlation effects is included in the calculations by means of second order Mpller-Plesset perturbation theory (MP2-FU/6-31G*), it is determined that there is no bond path connecting the inverted-tricoordinate carbons of rhombic C4. Since the existence of a bond path is a “necessary condition” for the existence of a bond, it is concluded that there is no formal bond between the bridging carbons of the rhombic C4 which is in contrary to the earlier assumptions. COPING WITH REGULATIONS. Mary Frances Dove , Div. of Natural Sciences, Mobile College, Mobile, AL 36613. Small colleges, both public and private, are under regulation by both OSHA and EPA. Unlike larger universities which usually have special departments whose responsibility is regulatory compliance, small colleges often suffer from a lack of specific information about regulations and the process of compliance. Our experiences at Mobile College, a small private college, have demonstrated the importance of organizing campus activities to ensure that reporting deadlines and safety standards are met. Small colleges need to develop up-to-date inventory and compatible storage systems, responsible waste disposal procedures, safety inspection routines, and worker right-to-know training programs for all campus personnel and areas involved in the handling and storage of chemicals. These activities should be carried out by a permanently designated site coordinator or safety officer who represents the college on the local emergency planning committee. 132 Abstracts Competitive Adsorption of Corrosion Inhibitors on Metal Surfaces A. Ibrahim, C. Jenkins, M. Emerson, and B.H.Loo Chemistry Department University of Alabama in Huntsville Huntsville, AL. 35899 (205) -895-6023 Surf ace -enhanced Raman Spectroscopic (SERS) studies of corrosion inhibitors on a copper electrode surface are reported. Competitive adsorption of benzotriazole (BTA) and tolyltriazoles ( 1-TTA, 5-TTA, 6-TTA) has been studied using Raman microprobe SERS. Preliminary results support the hypothesis of bidentate coordination to the metal surface through the 1,3 -nitrogens. SERS spectra of individual compounds on the surface of a copper electrode are compared with the spectra of mixtures taken under the same conditions. A Fast Fourier Transform algorithm is used to estimate the relative contribution of each component to the spectrum of the mixture. Studies of other similar corrosion inhibitors (e.g. benzothiozole) will also be reported. Diimide Kinetics In Aqueous Solution. David M. Stanbury, Department of Chemistry, Auburn University, AL 36849 2— The acid-catalyzed hydrolysis of azodiformate ((NC02)2 X which has diimide (N2H2) as an intermediate, has been studied by stopped-flow spectrophotometry. When the hydrolysis is conducted at sufficiently low pH (= 6), the second-order dismutation of diimide occurs on a time-scale slower than that of its generation. The reduction of azobenzene-4, 4'-disulfonate (ABDS) by diimide provides a convenient indicator of these reactions. The consumption of ABDS gives the relative rate constants of reduction and dismutation, and the kinetics gives the absolute rate constants. At 25 °C these rate constants are 2.5 x 104 M ^s * and 2.3 x 10^ M *s \ respectively. A mechanism is proposed in which the high-energy cis-diimide is in rapid solvent-catalyzed equilibrium with (ground-state) frcms-diimide; the cis-isomer reduces the azobenzene and trans-diimide competitively at rates near the diffusion limit. 133 Abstracts AN EXPERT SYSTEM FOR WASTE DISPOSAL: TOSS IT! USING EXSYS. Ann E. Stanley, Research Directorate, U.S. Army Missile Command, Redstone Arsenal, AL 35898-5248. About two years ago, we learned that we must adhere to a regu¬ lation called HAZCOM. This regulation requires employers to notify employees of the hazards to which they are exposed during work or in storage areas. We reacted in several ways to this measure. We in¬ ventoried all materials and placed Material Safety Data Sheets in work areas and storage areas. We initiated a program to educate employees about this regulation and how it impacted them. We began a program to identify all excess materials and to turn in those materials through our appropriate channels. A great deal of time was spent in the identification, cleanup and disposal of hazardous chemicals and other materials. This involved sorting through old and hazardous chemicals and packing the chemicals for transport to those responsible for disposal. We have only a few materials left to eliminate. In the course of this experience, I and members of my group, learned a great deal about the proper disposal of hazardous waste materials at the U.S. Army Missile Command. The expert system described herein is an attempt to incorporate our experiences into an expert system which will assist others in accomplishing the same task. Some of our activities were strictly regulated by MICOM Regulation 200-2. Others were discovered as we attempted to fathom our way through the maze of organizations involved. In my discussion I intend to relate some of my experiences during this time and to describe the expert system which I developed to assist others in this task. METAL COMPLEXES OF ALKYLATING AGENTS CONTAINING THE BIS (2-CHLOROETHYL) AMINE FUNCTIONAL GROUP. Jamie B. Neidert, Melvin D. Joesten, and Ethel L. Krasney, Dept, of Chemistry, Vanderbilt University, Nashville, TN 37235. 0 Cyclophosphamide (shown above) is a widely used anticancer drug. The active metabolite of this drug is phosphoramide mustard, (HO) (^N) P (O)N (CH„CH„C1) „ . Metal complexes of phosphoramide mustard deriva¬ tives with the general formula RR'P (O)N (CH-CH-Cl) where R=R'=NH2; R=-0-P (R' ) (O)N (CH^CH^Cl) 2 and R'^N^H^^ have been prepared. Complexes with two other anticancer drugs, melphalan and chlorambucil, have also been prepared and characterized. Transition, alkali, alkaline-earth, main group, and lanthanide metal ions have been employed, with the emphasis given to metal ions which exhibit anti¬ cancer activity such as Au(III), Cu(II), Pt(II), and Rh(II). The stoichiometry and spectral data for these complexes will be presented. The results of this study indicate that the phosphoramide mustard group in the ligands remains intact in the metal complexes. 134 Abstracts RADON SITUATION TODAY. Carlton D. Whitt, Retired Chemist and Teacher, 407 E. Washington St., Athens, AL 35611. Donald R. Payne, Dept of Physics, Athens State Col., Athens, AL 35611 The large amounts of money spent in testing for radon and for protect¬ ion against its hazards, the widespread concerns of the public and the many conflicting test results obtained to date, warrant an indepth study of the situation. The basic properties of radon gas and all the daughters of uranium were studied in detail. Simple calculations of the possible amounts of radium, radon and the daughters of radon based on the uranium contents of soils and minerals are presented. For example the amounts of radon gas contained in the total 10 feet of air over a one acre area and over a square mile at levels of 4.0 & 4,000 pico curies per liter of air were caculated to be: ACRE SQUARE MILE 4PCi _ 1n 4>000 PCi7 Radon, g. 3.21 X 10~JU 3.21 X 10"' Radon, ml. 3.25 X 10'8 3.25 X 10~5 4 pCi _ 4,000 pCi , 2.06 X 10'; 2.06 X 10"; 2.08 X 10"5 2.08 X 10'2 The amounts of uranium in the locale under study rigorously control the maximum amounts of each of its daughters including radium, radon and the short half-life daughters of radon. The disintegrations of atoms of uranium per second is the same as the number of atoms of each of the 14 daughters which react per second. It is independent of the half-life of each element. The authors will show that the amounts of radon and the daughters of radon as gaseous atoms or as dispersed atoms in the air are of little threat to our health. BON^ ENERGIES AND ENTROPIES OF GAS-PHASE ION-MDLECULE CLUSTERS: SO2 COp, SO^ N2O AND SO2 SO2. Andreas J. lilies. Kevin Snowden ana Matthew scanlon, Chemistry Department, Auburn University, AL 36849-5312. Ion-molecule clusters have been extensively studied, partly because of the, role they play in the chemistry of planetary atmospheres. Reactions of sulfur containing molecules are relevant to both the earth' s and the Venusian atmospheres . Studies of clusters are also important from the fundamental point of view. We have studied, and continue to study, neutral clustering to sulfur containing ions by experimental equilibrium methods using high pressure mass spectrometry . Fran the van't Hoff plots one can determine heats of reaction (and hence binding energies) and entropies of reaction. Exanples of the ions we have studied with preliminary experimental binding energies in kcal/mol are: SCu CCt (10.2), SCL |~12), and (~22) . The present binding energy for sCt SCu is higher than previous photoionization results. This difference can be explained by examining the Franck-Condon overlap in the photoionization experiments. Our results on reaction entropies, enthalpies and cluster binding energies of these and similar clusters will be presented. 135 Abstracts BORANE COMPETITION REACTIONS TOWARD N, P, AND As DONOR SITES. Larry K. Krannich, Dileep K. Srivastava, and Charles L. Watkins, Dept, of Chemistry, Univ. of Ala. at Birmingham, UAB Station, Birmingham, AL 35294. Prior research has established that BH3 binds to the nitrogen atom in Me2AsNMe2- We have recently shown that, depending upon the reaction stoichiometry, P-B, N-B, and B-P-N-B bonded BH3 adducts of Me2PNMe2 are formed. These studies have established the intramolecular competition of the As, N, and P atoms toward BHg. In the present work, we have focused on the intermolecular competition of N, P, P-N, and As-N base sites toward BHg. The reactions of BH-^’THF toward a series of solutions containing competing Group 15 Lewis base site compounds were studied using multinuclear nmr to establish the relative order of reactivity. Our data indicate the following order Me3N = Me2AsNMe2 > Me2PNMe2 = Me3P > Me3As toward BH3 in dg-toluene. This ordering will be discussed using electronegativity arguments for Me3E (E = N, P, As), group substitution effects, and the relative significance of dir-piT bonding in the As-N and P-N bonds. The results are in contrast to those determined previously from displacement reactions, i.e. Me3E + Me3E''BH3 - > Me3E' + Me3E ' BH3 , for establishing relative base strengths . MOLECULAR STRUCTURES AND DIMERIZATION ENERGIES OF DIGALLANES. Jerzy Leszczvnski and Koop Lammertsma; Department of Chemistry, University of Alabama at Birmingham, University Station PHS-219, Birmingham, AL 35294. The heavier atom analogues of diborane(6) are of both experimental and theoretical interest. Only as recent as 19SS has dichlorodigallane(6) been synthetized and studied by means of i.r. spectroscopy as well as gas-phase electron-diffraction. However, the information on digallanes is extremely limited. Our ab initio study supplies theoretical information about the molecu¬ lar structures, vibrational spectra and dimerization energy of these digallane species. The di-bridged molecule has been found to be minimum on the poten¬ tial energy surface, triply- and singly-bridged isomers were also investigated and characterized as first and second order transition structures. The com- parision between experimental and our theoretical data on H2Ga-/iCl2-GaH2 is quite satisfactory and shows that 3-21 G* basis set describes the molecular structure and the vibrational frequencies of these gallium species adequately. 136 Abstracts YOUR RIGHT TO KNOW. Johnnie Marie Whit field , Department of Chemistry, Millsaps College, Jackson, MS 39210. As of August 1, 1983, OSHA's Hazard Communication Standard (29 CFR 1910.1200), also known as Worker's Right-to-Know, went into effect. Originally . intended for the chemical manufacturing industry, litigation broadened its scope. Now employers, including private colleges and universities, must design and implement programs for their employees. The American Chemical Society is strongly encouraging the public acade¬ mic laboratories to adhere to the spirit of this program if they exist in states without comparable plans. The HAZ COM Standard also triggers nonmanufacturer compliance with Sections 311 and 312 of SARA Title III. Superfund Amendments and Reauthorization ACT (SARA) was signed into law on October 17, 1986. SARA Title III is also known as the Emergency Response and Community Right-to-Know (RTK) law. This talk will address the main requirements and impact of these RTK regulations. For HAZ COM these are : ' ( 1 ) development and implementation of a written Hazard Communication Program; (2) Material Safety Data Sheets (MSDS) ; (3) container labeling requirements; and (4) employee information and training. For SARA Title III these will include an audit of all hazardous chemicals (any element, chemical compound, or mixture of elements and compounds that is a physical or health hazard), whether these hazardous chemicals exceed specified thresholds and thus require reporting of Tier I or Tier II to Local Fire Department, Local Emer¬ gency Planning Committee (LEPC) , and State Emergency Response Commission (SERC). SERS of Dicyanogroups on Metal Surface Y. L. Pay, A. Ibrahim,, D. H. Burns and B. H. Loo Chemistry Department University of Alabama in Huntsville Huntsville, AL. 35899 (205) 895 -602 3 Surface-Enhanced Raman Spectroscopy (SERS) is used to study the molecular interactions of dicyanoalkanes with a copper electrode surface. The double degeneracy of the J (C—N) in the free molecule is removed when the cyano groups are adsorbed onto copper, showing that the two C=N groups are no longer chemically equivalent. Shifts in the nitrile peak position indicate that CN groups are pi-coordinated to the copper surface. 137 Abstracts STRUCTURE ANALYSIS OF PO L Y ETH Y LOX AZO L I N E-CO- PO L Y ETH Y L E N I M I N E AND ITS PRECURSOR. Key in W . Carter . Adriane G. Ludwlck and M. A. Salam Biswas, Chemistry Department, Tuskegee University, Tuskegee, AL 36088. The objective of this research is to examine the structure of po I y e+h y I oxazo I i ne-co-po I y e+h y I en ! m i ne ( PEOX-co-PE I ) , a potential therapeutic agent, and its precursor po I y ethy I oxazo I i ne (PEOX). PEOX-co-PE I is synthesized from the hydrolysis of PEOX. PEOX (Dow Chemical Company) is a c ommme r i c a I 1 y available water-soluble adhesive represented as repeat unit 1, sold in three molecular weight ranges. The PEOX-co-PE I can be consTdered a copolymer with the repeat unit 2. CH - -N-CHCH-N-CHCH- 2 ! 2 2 > 2 2 H 9 = 0 CH2 1 1 Preliminary NMR studies showed 2_ had been synthesized. Low angle laser light scattering (LALLS) measurements of the PEOXs gave weight average molecular weights simi lar to those reported by Dow. The PEOX-co-PEI results, however, Indicate that the PEOX backbone breaks during hydrolysis. Viscosity measurements of the PEOX-co-PEI polymer showed polyelectrolyte behavior in water and methanol. Huggins constants calculated for the PEOX systems indicated branching. Chromatograms from GPC studies of the PEOXs imply that PEOX is a mixture of components. The copolymers could not be distinguished by the columns used. From the results it Is concluded that the PEOX system appears to be a branched polymer with amide functional groups incorporated Into its backbone. The copolymer is inferred to be a mixture of linear polymers, some containing carboxylic acid end groups. (Supported by NIH RR 08091) -n-ch2- C = 0 CH, TERTIARY ARSINES: NOVEL SYNTHESIS. Dileep K. Srivastava, Larry K. Krannich, and Charles L. Watkins, Dept, of Chemistry, Univ. of Ala. at Birmingham, UAB Station, Birmingham, AL 35294. Recently there has been intense interest in organoarsine synthesis, since alkylarsines and designer III-V adduct precursors are being evaluated in the MOCVD production of GaAs for microelectronic technologies. Electronically pure arsines are reguired for this work. Although numerous synthetic pathways to organoarsines are known, undersirable side-reactions produce low yields or contaminants that are difficult to remove in the purification processes. We have been successful in developing a versatile, high yield novel synthetic route to highly pure tertiary arsines. Twelve alkyl and aryl tertiary arsines [R^As, where R = Et, Prn, Pr\ Bun, Busec, Bu1", vinyl, allyl, Ph, Bz, mesityl, and Me^SiC^] have been synthesized in good yields (65-90%) by reacting a stoichiometric excess of the alkylating agent (RMgX, RLi, or R2Zn) with OO^C^OAsCl and OCMe2CMe20AsCl . Furthermore, the mixed alkyl tertiary arsine, Et?AsMe, was prepared in 75% yield from the reaction of EtMgBr with OCT^CT^OAsMe. The desired products are easily isolated by distillation or recrystallization. All the synthesized arsines have been completely characterized by their IR, NMR, and mass spectra. Regardless of the alkylating agent, the tertiary arsine yield increased in the order Et < Prn < Bu11 < Ph. 138 Abstracts STOCHASTIC EVALUATION OF ALGORITHMS PROPOSED FOR REMOVING INTERFERENCE IN CHEMICAL KINETIC DATA. Michael L. Gibson and Michael B. Moeller, Department of Chemistry, University of North Alabama, Florence AL 35632. The dilute acid hydrolysis of cellulose involves a series of sequential reactions. Reaction products formed in the later phases of the reaction series interfere with the measurement of the hydrolysis rate by weight loss. We have developed a computer simulation of the reaction system in order to investigate and optimize two methods proposed for removing interference in kinectics data. The first of these methods involves fitting the data to a series of polynomial functional forms and estimating the hydrolysis rate constant from the average of the initial slopes. This method produced reliable values if there was little random error introduced in the simulated data, but this polynomial regression technique became unstable when the standard deviation was increased in the stochastically generated data points. In the second method examined, the effect of the interference was systematically reduced by using a conventional semilog plot and sequentially removing the last data points. The rate constant without interference was estimated by a linear extrapolation. After optimization, the simulations indicate this second method will give reliable values even with considerable scatter in the data. The Synthesis of Some New Derivatives of Acetophenone tricarbonyl chromium. B. Armstrong, M. Bowen, J. Hamilton, C.A.L. Mahaffy and J. Rawlings. Department of Chemistry, Auburn University at Montgomery, Montgomery, Alabama, 36193-0401, USA. A large number of alkyl and alkoxy substituted derivatives of acetophenone tricarbonyl chromium have been been prepared. The preparations together with some of the spectral properties will be described. One noticeable feature of these complexes is that 2 , 6-di-substituted compounds are yellow while complexes containing other substitutent patterns are orange to red. The extent of the requirement for bis-ortho substitution to restrict acetyl group rotation as an explanation for this phenomenon will be discussed. 139 Abstracts SYNTHESIS AND CHARACTERIZATION OF FLUORINATED EPOXY RESINS CONTAINING THE ESTER FUNCTIONAL GROUP. Derrick R. Dean and Adriane G. Ludwick, Chemistry Dept., Materials Research Lab, Tuskegee Univ., Tuskegee, AL 36088 . The objective of this study Is to synthesize a fluorinated epoxy resin containing the ester functional group. Based on the kinetic results from an experiment done by Griffith and O'Rear (Ind, Eng, Chem. Prod. Res. Dev., 1974, 13, 148-149), It is thought that such a resin s hou Id cure we I I with most common curing agents. Two synthetic approaches were used in this work. The first approach was aimed at developing a novel route for obtaining an ester-containing fluorinated resin 1. The proper conditions were determined using nonf I uor I nated analogs and then attempting each reaction with the fluorinated compounds. The first step in this synthetic scheme involved reacting benzene and hexaf I uoroacetone in the presence of aluminum chloride to obtain the monofunctional alcohol, ( 1 1 1 , 3 33-h exa f I uoro-2 -h y d roxy p rop y I ) bez ene , which was esterified by reaction with chloroacetyl chloride. This {(-haloester was then reacted with more hexaf I uoroacetone in an attempt to form the ester-containing epoxide. This final step proved unsuccessful, however. A second approach, the method of Maerker , Carmichael, and Port ( J , Or q . Chem,, 1961 , 55 , 2681-2688 ), which called for preparing a g I y c i d i c ester From the sa I ts of some long-chain fatty acids as we I I as from the acid itself, was employed. However, the acid used in this experiment, perf I uorog I utar i c acid, contains only five carbons. This work is still underway. (Supported by DOD/URI/ONR, contract no. N00 1 4-96-K-0765 ) SYNTHESIS AND CHARACTERIZATION OF POLYCARBOSILANES . Taleb H. Ibrahim and Adriane G. Ludwick, Chemistry Department, Materials Research Laboratory, Tuskegee University, Tuskegee, AL 36088. Polycarbosilanes are potential precursors for silicon carbide fibers and can be sintered to give materials which can be used as matrices for ceramic composites. The commercial method for the conversion of polydimethylsilane (PM) to a hexane-soluble polycarbosilane (reportedly 450 C, 14 hours, Ar atmosphere) gave a hexane-insoluble material in our laboratory. Reasoning from the thermal gravimetric analyses of PM and of the commercial polycarbosilane, modified conditions (350 C, 10 hours) were established for the PM to polycarbosilane conversion to give a product essentially identical to the commercial polycarbosilane. This approach has been used to establish the conditions for the production of polycarbosilanes from polymethylphenylsilane and from copolymers of dimethylsilane and methylphenylsilane. Polydiphenylsilane and polyborodiphenylsiloxane have been found to convert to a product containing polycarbosilane features in their infrared spectra. The molecular weights of the polycarbosilanes from polymethylphenylsilane and polydiphenylsilane have been found to increase as the reaction temperature increases. The influence of phenyl content on the properties of ceramic matrices prepared from polycarbosilanes is under investigation.

William Bleam, USDA/ARS-ERRC, Philadelphia, PA. P adsorpton on soil mineral surfaces is of concern in plant nutrition as well as environmental quality. Much research has been done to find a model to accurately describe this phenomenon. We studied P adsorption on laboratory synthesized Boehmite [ -A10(0H)], a soil mineral, at pHs 3.25, 4.00 and 5.50 using the Langmuir model and comparing its calculated adsorption maximum to that determined by direct measurement. The specific surface area determined by N2 adsorption and BET monolayer capacity was 187.25 M^/gm. P concen¬ trations used were below the Ksp of amorphous varascite, ALPO4H2O, at all three pHs in a system designed to eliminate precipitation as a factor in the surface reaction(s). The adsorption reactions con¬ formed to the linear Langmuir equation and peaked at pH 4.0. This suggested monolayer adsorption at singular sites but other surface techniques need to be used to explain the peak in adsorption at pH 4.0.

OPTICAL AM) MAGNETIC PROPERTIES OF RARE EARTH SUBSTITUTED YiBa2CV3°6+x. ’ Terry D. Rolin, B.H. Loo, D.R. Bums and N. Wang, Dept, of Chemistry , Univ. of Ala. in Huntsville, Huntsville, AL 35899. We have investigated the optical and magnetic properties of some rare-earth substituted Y,BapCuoO^ (Y123) compounds using a SQUID magnetometer and a Raman~microprdbe spectrophotometer, respectively. SQUID measurements were performed to determine values for diamagnetic shielding which gives the volume fraction of superconducting phase. Transition temperatures for each sample were also determined. The Raman spectra of these samples reveal modes centered approximauej_y at 320, 50*0 and 580 cm"1. The presence of thes modes correlates well with the presence of large values for diamagnetic shielding which suggests that these oeaks belong to the superconducting phase. 141 Abstracts ION MDLECULE CLUSTERING OF H30 TO C02 AND N^O. BOND ENERGIES AND ENTROPIES OF REACTION. Kevin Snowaen ana Andreas lilies; Auburn University, Auburn, AL 36849-5312. Ion-molecule reactions have been extensively studied mainly due to their relevance to astrophysical chemistry, atmospheric chemistry, nucleation phenomena and the chemistry of high energy environments such as plasmas, lasers and flames. Here we present new results on high pressure (<2.0 torr) ion-molecule reactions. H^O is an extremely import ant ion in our atmosphere. Many proton-bound molecules involving the H^O species have been reported, yet very few studies with H^O and inorganic molecules of atmospheric importance have been investigated. We studied the binding of H30 N20 and H^O CCu by high pressure ion-molecule equilibrium methods Z and found the binding energies to be 11.1 Kcal/mole and 12.1 Kcal/mol repectively. The experimental entropies of reaction are higher (less negative) then previous reports on similar molecules. Arguments which support the higher entropies of reaction are presented. MODEL COMPLEXES OF METAL NUCLEOTIDES. J. Rawlings, Chemistry Dept., Auburn University at Montgomery, Montgomery, AL 36193. 2+ Models for the Mg -ATP system have been synthesized using cobalt(III) or chromium(III) in place of magnesium. For example, the Co(NH3)3ATP complex resulting from the reaction of mer-[Co(NH3)3(H20)Cl2]Cl with ATP has been prepared. These substitution inert complexes have been purified using a variety of chromatographic techniques and have been characterized by their uv-visible and NMR spectra. The ability of these model complexes to inhibit the reaction of hexokinase with glucose has then been studied. COMPARATIVE RADON DANGERS. Donald R. Payne, Dept of Physics, Athens State College, Athens, AL 35611 . Carlton D. Whitt, Retired Chemist and Teacher, 407 E. Washington St. Athens, AL 35611 The large sums of money spent testing for and modifying buildings to protect against radon appears to be far out of proportion to the real threat for most US citizens. The radiation from radon and its daughter products can cause few problems greater than those caused by natural background radiation, cosmic radiation, x-rays, microwaves, or the world increase in radioactive elements released into the environment from nuclear power plants (naval and shoreside), weapons testing, and neutron activiation. Several waste disposal and energy use problems are far more significant in their effect on every person on the earth. 142 Abstracts GEOLOGY GEOCHEMICAL IMPLICATIONS FOR THE ORIGIN OF THIN-LAYERED AMPHIBOLITES WITHIN THE ROPES CREEK AMPHIBOLITE, WESTERN LEE COUNTY, ALABAMA. Greg D. Hall and Peter A. Salpas , Dept, of Geology, Auburn University. The Ropes Creek amphibolite is the largest exposure of rock in the Dadeville Complex of Alabama's Inner Piedmont, and is interpreted to be metamorphosed, obducted sea-floor basalt. Our mapping has re¬ vealed two rock types - a massive amphibolite (MA) and a thin- layered amphibolite (TLA) . There are three mechanisms by which layers in metamorphic rocks may be produced: (1) metamorphic differentiation of a homogeneous rock (2) alternating layers of meta-igneous and meta¬ sedimentary material; and (3) alternating layers of meta-igneous ma¬ terial and felsic tuffs. The TLA is composed of alternating bands (1-50 cm thick), contin¬ uous along strike, of well foliated mafic layers (ML) composed of 57% - 61% nematoblastic hornblende, 17%-23% plagioclase, and 14-18% quartz, and slightly foliated felsic layers (FL) containing 49% -55% subhedral plagioclase, and 40% -44% quartz. The ML and FL have distinctly dif¬ ferent major element compositions, and mass balance calculations pre¬ clude derivation of the TLA by metamorphic differentiation of the MA or any reasonable basaltic composition. The modal mineralogies of the FL plot in the dacite field on Steckeisen's diagram, consistent with their major element compositions which are enriched in Si and depleted in Mg, Ca, Fe , and Al relative to the ML. Major element compositions of the ML are similar to tholeiite basalts. REE compositions are also different between the ML and FL. The ML exhibit flat to slightly LREE-depleted patterns. The FL are slighty LREE- and MREE-depleted and have large positive Eu anomalies. Mass balance calculations using REE also prohibits deriving the ML and FL by segregation of a common basaltic parent. SINKHOLE OCCURRENCE IN ALABAMA AND THE EASTERN UNITED STATES. J. G. Newton and Philip E. LaMoreaux, P. E. LaMoreaux and Associates, Inc. P. 0. Box 2310, Tuscaloosa, Alabama 35403. More than 1,000 sites of sinkhole development have been identified during a series of investigations in Alabama and the eastern United States. It is estimated that more than 8,000 collapses have occurred at these sites with most occurring since 1950. Costs of damage and safety measures reported for a limited number of sites exceeded $170 million . Sinkhole occurrence is both natural and induced (accelerated or caused by man). Almost all occurrences result from the collapse of. soil cavities or the downward migration of unconsolidated deposits into openings in bedrock. Most occurrences and damage are induced. These man-related collapses are divided into two types: those resulting from ground-water withdrawals and those resulting from construction. Sinkholes resulting from water-level declines due to pumpage are caused by loss of buoyant support, increase in velocity of water movement, water-level fluctuations, and recharge. Most induced sink¬ holes resulting from construction are caused by the diversion or impoundment of surface drainage over unconsolidated . deposits resting on openings in the top of bedrock. Collapse mechanisms include loading, saturation, and piping. 143 Abstracts FUNCTIONAL HEARING IN MOSASAURS REASSESSED . James P. Lamb, Jr., Red Mountain Museum, 1421 22nc* St. So., Birmingham, AL 35205 Most researchers studying mosasaurs have concluded poor hearing for these animals since mosasaurs lack the specialized adaptations of ce¬ taceans for underwater hearing. Mosasaurs, being reptiles, could not possess the underwater hearing adaptations of the cetacea, since their immediate ancestors did not have a similar middle ear system to that of cetacean ancestors. The middle ear in mosasaurs differs from that of their terrestrial lizard ancestors in that the stapes proper has been shifted from its articulation with the extracolumellar process of the stapes ( hence with its articulation to the tympanic membrane ), to fit into a pit ( the stapedial pit ) on the quadrate. The extra¬ columella and tympanic membrane have fused to each other and ossified, and the extracolumella runs through the peculiar stapedial notch of the mosasaur quadrate to articulate ligamentously with the mid-shaft of the stapes proper. This system allowed mosasaurs to recieve audi¬ tory vibrations in two ways, the " normal " way, via the stimulation of the tympanic membrane, and by low-frequency vibrations recieved by the lower jaw unit. These vibrations would pass the length of the jaw ( as they do in some cetaceans by the way ) to the dense quadrate, then to the stapes and inner ear. This system allowed for probably ex¬ cellent reception of low-frequency sound, which would be most impor¬ tant for aquatic predators .The fact that the stapedial pit is in abso¬ lute terms as large in newborns and juvenilles as adults indicates that young were born with a well-developed hearing apparatus, and may indicate birth at an advanced stage of development. This research based in part on specimens from the Tyrell Museum of Paleontology, Canada, and from specimens in the collections of Red Mountain Museum. CORRELATION OF SOIL ASSOCIATIONS TO GEOLOGY AND MINERAL RESOURCES OF ELMORE COUNTY, ALABAMA. Lewis S. Dean, Geological Survey of Alabama, P.O. Box O, Tuscaloosa, Alabama 35486 During an evaluation study of the mineral resources of Elmore County, Alabama, a preliminary correlation was made between previously mapped soils and their related parent lithologies. Elmore County, Alabama, located in the east-central part of the state, contains a variety of mineral resources situated in two physiographic/geologic regions--the Piedmont and Coastal Plain provinces. A regional unconformity separates the two geologic pro¬ vinces. Sand and gravel, clay, and silica sand have been produced from Coastal Plain sediments. Stone has been produced from the Piedmont Province, and gold, mica, and garnet occurrences have been prospected. Elmore County is one of the State's leading producers of sand and gravel and clay in Alabama. Three major groups of soil associations are recognized in the county, those of- the Piedmont Plateau, Coastal Plain, those of the major flood plains and terraces. Soil associations are useful in distin¬ guishing variation in Coastal Plain and Piedmont lithologies, particularly along the Fall Line, and in mapping different Quaternary terrace deposits from which the principal production of clay, sand, and gravel is derived. Correlation of soils with geologic lithologies, including Quaternary terrace and alluvial deposits, Cretaceous sediments of the Tuscaloosa Croup, and igneous and metamorphic rocks of the Piedmont can provide information on thickness, areal distribution, overburden, texture, topographic position, and parent material of potential mineral resource deposits. 144 Abstracts MONTGOMERY THEROPOD : A STATUS REPORT. James P. Lamb, Jr., Red Mountain Museum, 1421 22n St. So., Birminham, AL 35205 In the summer of 1982, David and Janet. King ( Auburn Univ. , Auburn, A1 ) , discovered the bones of a carnivorous tyrannosaurid dinosaur in Montgomery County, Alabama. The specimen, found in a 77-million year- old stratum of the Demopolis Chalk Formation, ( normal-nearshore ma¬ rine ) , represents a carcass which was transported via currents into the offshore marine environment where it sank and was preserved by rapid sedimentation. Jim Dobie and Dan Womochel ( Auburn Univ., Auburn AL, and Univ. TX, Odessa ) excavated portions of the specimen in 1982. The. author, Gorden Bell ( previously of Red Mountain Museum, now Univ. Tx, Austin ) , and field crew of Red Mountain Museum, Birmingham, AL, excavated the majority of the specimen in 1984 and 1986. Currently, the specimen resides at Red Mtn. Museum, where it is being prepared from the rock matrix. The specimen is represented by approximately 1/2 of the skeleton. Elements so far identified are: right dentary, left maxilla-premaxilla, two complete pes units , both tibiae, both fibu¬ lae, and portions of the pelvic girdle. Also numerous teeth and rib fragments are represented. Bones still in jackets may include: Left dentary, right maxilla, basicranium and skull roof, as well as a par¬ tial humerous . Both femora and most of the vertebral column are miss¬ ing. While recognizing that there may be some problems with the vali¬ dity of the tyrannosaurid genus name Albertosaurus , the specimen is provisionally referred to that taxa based on measurements and direct comparison with material from the Tyrell Museum of Paleontology, Al¬ berta, Canada, This specimen most complete, best preserved theropodous dinosaur from the eastern U.S, and the only substantiable record of Albertosaurus . PRELIMINARY INVESTIGATIONS ON THE ORIGIN OF RHYTHMIC BEDDING IN THE PALEOGENE CLAYTON FORMATION. Richard A. Huchison, Jr. , and Charles E. Savrda, Dept . of Geology, Auburn University , Auburn, AL 36849-5305 . The Pine Barren Member of the Lower Paleocene Clayton Formation of Alabama is characterized by well-developed rhythmic alternation of poorly resistant, olive-gray, silty, organic-rich, calcareous mudstones and indurated, light gray, organic-poor limestones. Average bedding- couplet thickness is approximately 65-70 cm. Similar decimeter-scale rhythmic bedding of carbonate-rich and carbonate-poor lithologies is common in many fine-grained stratigraphic sequences, particularly of Cretaceous age, and has been attributed to a variety of paleoenviron- mental mechanisms including cyclic variations in 1) bottom-water redox conditions, 2) degree of carbonate dissolution, 3) influx of fine¬ grained elastics , 4} carbonate productivity, and 5) bottom-current activity. These cycle types can often be distinguished through detailed study of general bedding characteristics, primary and biogenic structures, macro- and microfossil content, and sediment texture, composition, and geochemistry. This approach is currently being employed on a continuous and well-exposed section of the Pine Barren in Lowndes and Butler Counties, central Alabama. In conjunction with lateral stratigraphic relationships established through the analysis of additional outcrops and water-well data from across the state, this study will provide an improved understanding of the paleoceanographic and paleoenvironmental processes that influenced deposition on the Alabama shelf during the Paleocene. 145 Abstracts TRACE FOSSILS WITHIN A LOWER PALEOCENE TRANSGRESSIVE SEQUENCE, WESTERN ALABAMA. Charles E. Savrda, Department of Geology, Auburn University, Auburn, AL 36849-5305. Trace-fossil assemblages in the Lower Paleocene Clayton and Porters Creek Formations of western Alabama reflect sea-level-modulated changes in paleoenvironmental conditions. The basal "Clayton sands" contain pervasive box-work systems of Thalassinoides that were emplaced during times of relative quiescence in high-energy, shallow marine environments generated during initial pulses of rapid transgression. The bulk of the Clayton Formation overlying the basal sand is characterized by alternating mudstones and indurated sandy limestones that record later-stage transgressive, highstand, and possibly minor regressive phases. Diffuse burrow mottling and rare, small discrete burrows (e.g., Chondrites and Planolites) characterize the mudstones and indicate relatively quiet conditions, soupy substrates, and oxygen- depleted pore waters. Vertically extensive Thalassinoides dominate the limestones and reflect periods of slower sedimentation and/or winnowing associated with intensified bottom-current activity. Rhythmic bedding in this interval may be in response to minor sea-level fluctuations and/or climate-induced scour cycles. The upper few meters of the Clayton Formation and the lower part of the overlying Porters Creek Formation reflect sea-level rise of a higher magnitude. This package includes, in ascending order, a relatively clean white chalk, gray marlstones, and olive black clays. The chalk bed contains Thalassi¬ noides , Planolites, Chondrites , and Zoophycos . As carbonate decreases and organic carbon increases up-section away from the chalk, the diver¬ sity, size, and depth of penetration of burrows decrease, reflecting a progressive, sea-level controlled decrease in benthic oxygen levels. GEOMETRIC MODEL OF A RAVINEMENT SURFACE IN THE UPPER POTTSVILLE FORMATION, NORTWESTERN ALABAMA. Yuejin Liu and Robert A. Gastaldo, Department of Geology, Auburn University, AL 36849 A ravinement surface was recently discovered above the Mary Lee coal zone of Lower Pennsylvanian Pottsville Formation in the Black Warrior Basin of northwestern Alabama. This ravinement surface is disconf ormably underlain by lagoonal and alluvial swamp deposits and overlain by a thin ravinement bed. Two types of ravinement beds are identified: (1) shale beds with in situ bivalve and brachiopod assemblages, and (2) sandstone beds characterized by Zoophycos and allochthonous trilobite-crinoid-brachiopod assemblages. The ravine¬ ment surface was produced as a result of the migration of an erosional shoreface during sea-level rise. Under subcritical conditions wherein the shoreface angle is greater than its climbing angle, gradual rise of sea level causes erosion of the existing shoreface. This continuous process produces two final results: (1) the formation of a ravinement surface consisting of a series of erosional surfaces, and (2) the deposition of ravinement beds. The geometry of the ravinement surface is controlled by the climbing angle of the shoreface. The ravinement bed sediments are derived from material eroded from the shoreface, and controlled by the properties of the shorelines within the coastal- deltaic systems. Shale beds are associated with lagoonal and alluvial swamp shorelines, whereas sandstone beds are connected with barrier island shorelines. 146 Abstracts TOPOGRAPHIC ANALYSIS OF STREAMS TO DETERMINE GROSS CHARAC¬ TERISTICS OF BEDROCK FRACTURE-ZONE PATTERNS. Thomas J. Carrington , Carleton W. Degges, and Steven C. Bearce, Department of Geology, Auburn University, AL 36849-5305. Orientations of 551 rectilinear stream segments (RSS) were obtained from 7.5 minute, U.S.G.S. topographic maps covering the Piedmont portion of the Little Uchee Creek basin, Lee County, AL. RSS peaks equal to or greater than the mean concentration factor were compared with similar peak concentrations of 1,349 joints and 493 foliations from the same area, showing a correlation of 77.7%. Com- parisions of RSS-to- joint/foliation from the structural units comprising the area [Pine Mountain (PM) , Bartletts Ferry fault zone (BF) , amphibolite sequence (AS) , Goat Rock fault zone (GR) , and Motts gneiss (MG)] revealed, respectively, 70, 42.8, 58.3, 54.5, and 58.3 percent cor¬ relations. Only on the AS, GR, and, MG blocks did major RSS peaks correlate with major peaks of joints and/or foliation. Comparison of major RSS peaks with relatively minor joint/foliation peaks improved correlations signifi¬ cantly. This suggests control of stream-valley erosion by the relative degree of "openness" of preferred joint di¬ rections. Major RSS concentrations in the area are from N. 6-22° w. and range between 71° and 87° from major foli¬ ation peaks, indicating that stream valleys are preferen¬ tially developed along extension joints.

THE PERSISTENCE OF FORESTED SWAMP ENVIRONMENTS IN A PENNSYLVANIAN COASTAL-DELTAIC SYSTEM, NORTHWESTERN ALABAMA. Timothy M. Deroko and Robert A. Gastaldo, Dept, of Geology, Auburn Univ. , AL 36849 Tine sediments of the Mary Lee coal zone of the Lover Pennsylvanian "Pottsville" Formation in Walker County, Alabama record deposition in peat swamp and alluvial swamp environments. Peat swamp environments are represented by the dagger, Blue Creek , Mary Lee, and Newcastle coal seams. These coals are low to moderate in ash, indicating isola¬ tion from clastic deposition. Standing forests of erect lycopods and calamites, along with lycophyte-dominated forest-floor litter horizons, are preserved immediately above these coals. These accumulations of autochthonous plant material represent the last vegetational elements of the peat-accumulating swamps and mark the senescence and death of these swamps due to incursion by clastic material, initially by high magnitude floods. Although these swamps no longer accumulated peat, growth of forest vegetation continued in alluvial swamp environments. Alluvial swamp environments are represented by mudstone, shale, and silty shale sequences between coal seams. These facies contain multiple forest-floor litter horizons identified by : 1) pteridosperm- dominated litter accumulations, 2) mud-cast prostrate logs, 3) stig- marian root axes and other rooting structures, and 4) erect, in situ lycopod. and calamites trunks. Probable regulatory mechanisms for alteration of peat swamp and alluvial swamp facies involve fluctuating clastic depocenters due to subsidence on two scales. Subsidence on a local scale, over a relatively short period of time, was probably due to differential compaction of buried peat swamps. Subsidence on a regional scale, over a longer period of time, may have been tectonically controlled. 147 Abstracts FORESTRY, GEOGRAPHY, CONSERVATION, AND PLANNING "DRASTIC" MODEL AS A TOOL FOR PLANNERS CONCERNED WITH GROUNDWATER PROTECTION, Frank N, Himmler and Priscilla Holland, Department of Geography, University of North Alabama, Florence, AL 35632-0001. The "DRASTIC" model is a standardized system for evaluating groundwater pollution potential using hydrogeologic settings. The model was developed by the U.S. Environmental Protection Agency in cooperation with the National Water Well Association at the Robert S. Kerr Environmental Research Laboratory in Ada, Oklahoma. "DRASTIC" employs seven parameters, Depth to water table, net Recharge, Aquifer media, j>oil media, Typography, _Impact of the vadose zone and hydraulic Conductivity of the aquifer. The seven parameters create the acronym from which the model acquires its name. Each parameter is mapped, weighted and rated. The sum of weighted rates for each unit of area on the map is its pollution potential index. The "DRASTIC" model is being integrated into a geographic information system (GIS) which is run on an IBM PC/AT micro-computer using Earth Resources Data Analysis Systems (ERDAS) software. The results will eventually become part of the already existing Shoals Industrial Development Information System (SIDIS) data base housed at the Geographic Research Center of the University of North Alabama. Planners may use these results as a basis for locating activities such as heavy industry or landfills which may pose a threat to groundwater supplies. This pilot study focuses on the "Tuscumbia Quadrangle - 7.5 Minute Series (Topographic)" produced by the U.S. Geological Survey. This location is in the Tennessee Valley of northwestern Alabama. Funding for this research has been provided by a grant from the Alabama Universities — TVA Research Consortium (AUTRC) . URBANI ZAT I ONAL INFLUENCE ON THE CAHABA RIVER BASIN SINCE 1930. William Timothy Wynn, Department of Geography, University of Alabama , Tuscaloosa, AL 35487, Over the past fifty years the Birmingham Metropolitan area has grown at a steady rate with urban sprawl and population growth being at an all time record high. Urbanization brings with it changes in land use, which disrupts the natural landscape, replaces it with impervious surfaces, and redistributes the land surface flows of the hydrologic cycle (Lazard, 1979). The objective of this research is to examine the urban factors that have presented water quantity problems for the Cahaba River Basin and to develop coefficients to be used in rainfall/runoff relationships for three different time periods ( 1920' s, 1950's, and 1980' s). 148 Abstracts COMPUTER AIDS FOR PLANNING COMMUNITY SOLID WASTE RECYCLING PROGRAMS. Michael William Mullen, Center for Environmental Research and Service, Troy State University, Troy, Alabama 36082. Due to decreasing landfill capacity and increasing landfill costs many communities are beginning to look at recycling as a partial solution to their solid waste management needs. Both the opinions about the capability of recycling to help meet solid waste management needs and the options for recycling programs are numerous and diverse. The only real way for a community to assess the potential recycling has in their solid waste management system is to examine recycling in a broader planning context. Since so many variations or options exist for recycling programs it would be inefficient and unwise to perform a detailed evaluation of every option. Fortunately, simple computer models are available which can be used early in the planning process to reduce the number of options which should be examined in a detailed manner. This paper describes how one such model, the RECYCLE model, can be applied to planning. It also presents some model inputs and outputs which show how local factors influence the economic feasibility of different recycling options . EVALUATION OF UPPER CRETACEOUS WATER RESOURCES OF THE MONTGOMERY AREA, ALABAMA. Scott B. Couch, Dept, of Geography, University of Alabama, University, AL 35487. Water levels fluctuate on an almost continual basis. This is in response to discharge from and recharge to aquifers by natural and artificial means. Water level changes may be affected by atmospheric conditions, changes on the earth's surface, and subsurface processes operating within the earth itself. In recent years, there has been much concern about the ground water resources available within Alabama and the susceptibility of these resources to contamination. This author will focus on evaluating the characteristics of the major aquifers within the Upper Cretaceous depositional sequences of the Montgomery area. 149 Abstracts FUNCTIONAL CHANGE IN THE CENTRAL BUSINESS DISTRICT: A CASE STUDY OF TUSCALOOSA, ALABAMA. Jeffrey P. Richetto, Dept, of Geography, Univ, of Alabama, Tuscaloosa, AL 35487-0322. D. Michael Henderson, Dept, of Geography, Univ. of Alabama, Tuscaloosa, AL 35487-0322. Since the mid 1950s there has been a significant spatial reorganization of human and economic activities within the North American city. In response to the continuing suburbanization of the urban population; retail, commercial, and ancillary activities have decentralized. In the wake of this abandonment of the central business district by the economic activity sector, several office and service- related functions have found the rental opportunities in the central business district attractive. Thus, in order for local government and booster organizations to more effectively target their resources for reinstating the economic competitiveness of the central business district, it is necessary to identify those traditional tertiary activities responding to decentralisation forces and those office and service activities that are sensitive to the centripetal forces operating within the central business district. Within this context, this study (1) traces the extent of economic activity decline in the central business district by type of activity and where, in general, relocation occurs, (2) examines the in-migration of office and service activities into the central business district by type of activity as well as factors underlying this pattern, and (3) investigates the extent to which the availability and patterns of low-cost rental opportunities affect the spatial distribution of both retail and office activities.- The City of Tuscaloosa, Alabama serves as a case study. RE-USE OF ABANDONED RAILROAD RIGHTS-OF-WAY FOR RECREAT¬ IONAL OPEN SPACE. Timothy C . Balentine , Univ. of Ala., Tuscaloosa, AL 35487. Since the heyday of the Railroad Age in the 1920's, thousands of rails have been abandoned. Many of these railroads have been converted to trails for recreational open spaces. Most of these conversions in the United States have taken place in the Northeast and Northwest. Many obstacles must be overcome in the creation of these trails. Each project is unique; topography, status of the tracks, and the aesthetics provide both positive and neg¬ ative aspects to each project. After a general foundation is layed, the basic principals will then be applied to the Holt Junction of the L & N line in Tuscaloosa to illus¬ trate the potential and problems that abandoned railroad beds offer. 150 Abstracts D£vU?mI. fN° PR0SPECTS F°F SUSTAINABLE FOOD PRODUCTION ?™^ALL SCALE PARSERS IN ZIMBABWE: THE INFLUENCE OF eFO^SfiPwvRnL P0LICIES- PETER S. NGWAZIKAZANA, DEPT. OF GEOGRAPHY, Uni v of Ala . , Universit y , A1 . 35486-3958 . Professor J. Harlin of The Dept, of Geography , Univ . of Alabama provided much appreciated advice and help in the course of this research. Typically, the mass media highlights the food shortages that periodically ravage different regions of sub-Saharan Africa and ignores the apparent successes of such countries as Zimbabwe since 1980 to be self-sufficient in their food requirements . This means that whatever "lessons" these rare cases might hold for the rest of the region go unheeded. A judicious mix of policies seems to have successfully brought an increasing number of small scale farmers into food production for both the home and export market inspite of the drought . However new imbalances and constraints threaten the long term sustainability of Zimbabwe’s initial gains. Flexible approaches to policy formulation and implementation are needed to minimise these threats . A CENTER OF EXCELLENCE IN GEOGRAPHIC EDUCATION. William R. Strong, Dept of Geography, Univ. of North Alabama, Florence, Alabama, 35632. A program funded in 1987 by the Fund for the Improve¬ ment of Post Secondary Education established eight Centers of Excellence including the University of North Alabama. The original proposal title read as follows: " The project aims primarily to improve the degrees of correspondence between the geographical content of the middle school curriculum and the content of col lege- level geography courses which are used to educate teacher candidates in social studies and geography. During the three year project, each Center is to design a course syllabus that is sensitive to the requirements of the state social social studies course of study, teach that syllabus on a trial basis in special graduate courses or summer institutes, publish the results, and incorporate the syllabus into p re- service geography courses at the college level. This paper reports on the proposal, objectives, instructional programs, results of the first year in Alabama, and future directions. 151 Abstracts PHYSICS AND MATHEMATICS CALCULATION OF VELOCITY PERTURBATIONS AND DIRECTIONALITY OF THE FRAGMENTS IN SATELLITE FRAGMENTATION EVENTS. R. C. Reynolds, Lockheed Engineering & Science Company, Houston, TX 77058, G. D. Badhwar, NASA Johnson Space Center, Houston, TX 07758 and A. Tan, Department of Physics, Alabama A & M University, Normal, AL 35762. The magnitude, variance and directionality of the velocity perturbations of the fragments of a satellite can shed valuable information regarding the nature and intensity of the fragmentation. Up until now, the only method used to calculate the three orthogonal components of the velocity change consisted of inverting the process of evaluating the changes in the orbital elements of the fragments due to velocity perturbing impulses. But the traditional method failed in various occasions, giving singularly high values for the radial and the cross-range components. This paper describes a new method of calculating the velocity perturbations, which is free from the shortcomings of the traditional method and could be used in all occasions, provided the fragmentation data and the orbital elements data are true and consistent with one another. The method uses the parent satellite's local frame of reference at the time of breakup. The three orthogonal components of the velocity change are derived from the three simultaneous equations provided by the changes in specific energy, specific angular momentum and plane angle of the fragment. The directionality of the fragment is studied by defining two angles, the colatitude and the longitude of the fragment in the parent satellite's local frame of reference. The preferred directionality of the fragments of Landsat 1 and Landsat 3 rockets indicates that these rockets most likely broke up in the "clam" model of low intensity explosion. ASTRONOMICAL PHOTOELECTRIC PHOTOMETRY AT THE UNIVERSITY OF NORTH ALABAMA. David R. Curott, Department of Physics and Earth Science, University of North Alabama, Florence, AL 35632. Small telescopes in the Alabama environment can make valuable contributions to the astronomical database if they undertake a program of photoelectric photometry of variable stars. Such a program, recently begun at the University of North Alabama, is described. This work was supported by a UNA Faculty Research Grant . 152 Abstracts OPTIMUM CHARACTER ENCRYPTION AND EXTRACTION FOR OPTICAL CORRELATION TECHNIQUES. Larry D. Brasher. James F. Hawk and James C. Martin, Physics Department, Univ. of Alabama at Birmingham, Birmingham, AL 35294. Don A. Gregory, U. S. Army Missile Command, AMSMI-RD-RE-OP, Redstone Arsenal, AL 35898. An important subset of pattern recognition applications permit the representation of data by characters which have been optimized for the type of data and the type of search to be performed. An example of this is the search for biologically important patterns within the sequences of nucleotide subunits of deoxyribonucleic acid (DNA). In this case the four distinct subunits of DNA must be represented and "wildcard" or metacharacters are needed to permit flexible searches for sequence patterns. Due to the rapidly increasing availability of DNA sequence information, more rapid and interactive analytical techniques are needed to make full use of this data. This study seeks to design optimal characters for use in an optical correlator recognition device. Characters which are compact, easily distinguishable and compatible with current coherent light modulators have been designed. Preliminary work on these representations has been guided by computer modeling of the optical recognition process. Promising characters have been tested experimentally in a VanderLugt system. The use of laser printers and photo-typesetters to prepare original test images will be discussed. SOME SURPRISES IN THE THEORY OF FINITE GAMES. Olav Kallenberg, Dept. Algebra, Combinatorics and Analysis, Auburn University, AL 36849. If a roulette game is repeated indefinitely, and if you are free to choose, based on your past experience, in which games to partici¬ pate, then obviously you cannot do better than choosing all the games. Playing red and black on a card-deck seems different: Here your past experience gives information about the future, so you might expect to improve your chances by a clever strategy. However, a closer analysis yields conclusions which seem contradictory to all common sense. (Some of the mathematics involved here is rather sophisticated, but the present talk will be kept on a heuristic and non-technical level.) 153 Abstracts TRACK RECONSTRUCTION OF HIGH ENERGY PARTICLE INTERACTIONS ON THE ALABAMA SUPERCOMPUTER, C. Merrill Jenkins and R. Kent Clark, Dept, of Physics, University of South Alabama, Mobile, AL 36688 In a recent experiment at the Fermi National Accelerator Laboratory about 5000 tapes (0.6 Tbytes) of dat| were accumulated. _This experiment used a beam of positive ( n , p) and negative ( * , p) particles on a lithium target at 300 GeV/c in a study of the hadronic production of J/ik particles. To reduce this data set in a timely fashion, some of the world's most powerful computing facilities are utilized. At the University of South Alabama we have begun using the Cray XMP/24 at Huntsville to locate and define particle paths through the experiment's spectrometer . The experiment is studying hadronic states that decay into the J/ + y • The experimental spectrometer utilizes charge track detection (proportional wire chambers and drift chambers) with a momentum analysis magnet, electromagnetic shower detection (Pb-glass and scintillating glass) and muon identification. The tracking program we are using on the Alabama Supercomputer currently takes 0.173 seconds/event cpu time. We will briefly discuss the physics of the experiment, the experimental set-up and the method of employing the Alabama supercomputer in the data reduction. Benchmark results will also be presented. RESEARCH INTO SEVERAL FACTORS AFFECTING THE UNDERSTANDING OF BASIC PHYSICS CONCEPTS. Dennis A. Likens, Dept, of Physics, Tuskegee University, Tuskegee, AL 36088. The learning of basic physics concepts by engineering majors seems to be largely unaffected by teaching techniques, laboratory procedures, and the instructor. Instead, student learning appears to be influenced by factors largely outside of the control of the instructor. These factors include the student's earlier educational experiences, grade point average, and entrance scores. 154 Abstracts CALCULATIONS OF METALLIC AND NONMETALLIC ELECTRON CONCENTRATION IN INTERMEDIATE CONCENTRATION REGION FOR DOPED SEMICONDUCTORS. Shiva Shankar Subramanyam , I. K. Kothari, and P. C. Sharma , Department of Physics, Tuskegee University, AL - 36088 In doped semiconductors with low doping, the electrons are bound and with high doping, the electrons are free. But in the intermediate concentration region of metal-nonmetal transition, it is concluded by this work that the electrons exist in a mixed state, i.e., partly in metallic (free) state and partly in non-metallic (bound) state. Using the concept developed here the electron concentration in nonmetallic (Nyj) and metallic (N^) regions are calculated and it is found that for low doping concentration N^N^ , for high doping concentration NtrNmand for intermediate doping both N y\ and N^ are appreciably significant.

William J. Boardman, Div. of Science-Math, Birmingham-Southern College, Birmingham, AL 35254. First posed by the Portugese astronomer Pedro Nunes in 1542, the question: "What day of the year has the shortest twilight?" was investigated by Bernoulli and d'Alembert, and is discussed in Heinrich DBrrie's 100 Great Problems of Elementary Mathematics . This investigation relaxes the assumption usually made for simplicity, that the evening twilight begins when the true center of the sun is on the horizon. 155 Abstracts MAGNETIC RESONANCE STUDY OF THE PROTONS IN THE HYDRATED COMPLEXES OF COBALT: LANTHANUM ZINC DOUBLE NITRATE. Henry W. Glotfelty, Dept, of Physics, Samford University, Birmingham, AL 35229. J. W. Culvahouse, Dept, of Physics, University of Kansas, Lawrence, KS. The proton ligand magnetic hyperfine tensors of the X and Y sites of the Cobalt: Lanthanum Zinc Double Nitrate (Co:LaZnDN) crystal have been determined from an Electron-Nuclear Double Resonance (ENDOR) investigation. The X and Y sites are distorted, hydrated complexes of the form Co (6^0)2+. A symmetric (six parameters) hyperfine tensor was found for each of the four non-equivalent protons of the X site. Since the trigonal distortion of the Y site is quite large, a nine parameter ligand hyperfine tensor was found for each of the two non-equivalent protons of the Y site. In addition, the proton contact interactions of the X site were found to be close to the values found for the X site protons in Cobalt: Lanthanum Magnesium Double Nitrate (Co:LaMgDN). It was found that the major part of the ligand magnetic hyperfine tensor for the X and Y site protons could be explained by the magnetic point dipole-dipole interaction. All ENDOR measurements were made at 4.2K. The research was supported in part by a grant from the National Science Foundation. 0>N" NIL1DEALS OF LOCAL r-RSI RINGS. Haghdad S. Memauri , Department of Mathematics, Tuskegee University, Tuskegee, AL 36088. It is of interest to know under what conditions certain nil ideals of a ring are nilpotent. Among im¬ portant ideals of a ring R is J(R), the Jacobson radical of R. In my earlier work I have shown that if R is a r-SI as an R-module, then the condition that J(R) nil implies it is nilpotent. In this article along with some other results we show that if R is a local r-RSI ring which is either a PI ring or J(R) is of bounded index, then J(R) nil implies it is nilpotent. 156 Abstracts ELECTRON-PHONON INTERACTION IN DOPED MATERIALS AND ITS INFLUENCE ON THERMAL CONDUCTION IN THE ULTRALOW TEMPERATURE REGION OF 5-35K, P.C, Sharma, department of Physics, Tuskegee University, Tuskegee, AL- 36088 , The electron-phonon scattering in the intermediate donor concentration region has been studied. At low concentrations, below metal-insulator transition, the donor electrons are bound to the impurity atoms and at high concentrations they are free in conduction band. According to our model the electrons are in a mixed state, both in metallic and non-metallic state. The electron concentrations in both metallic and non-metallic states are calculated for each sample and the theory of both bound electron-phonon and free electron-phonon scattering are applied to P-, As- and Sb-doped germanium and P- and Li-doped silicon samples. The values of density- of-states effective mass and deformation potential constants have been calculated by our model and are compared with experimental values .

A. Tan, Department of Physics, Alabama A & M University , Normal , AL 35762 . By treating heat flux as "rays", the laws of rectilinear propagation, reflection and refraction of heat conduction rays through material media are derived. It is shown that total internal reflection of thermal rays is unattainable. The condition of extremum deviation of thermal rays at the surface of separation of two media is determined . The same for refraction through a thermally resisting wedge is obtained via the principle of reversibility. Finally, a variational principle for heat conduction rays is obtained, from which the laws of rectilinear propagation, reflection and refraction can be derived as special cases . *This work was partially supported by NSF-MRCE grant. 157 Abstracts TEACHING SAMPLE VARIANCE: DIVISOR n, n-1 , n+1,...? Satlsh Chandra Misra, Dept, of Math & Comp. Sc., Tuskegee Univ., Tuskegee, AL 36088 and Hardeo Sahai, Dept, of Biostat., Univ. of Puerto Rico, San Juan, PR 00936. The usual sample variance is defined as the sum of squares of deviations of sample observations from the sample mean divided by n-1, where n is the number of independent, identically distributed observations from the population. This estimate of the population variance is unbiased in the sense that its expected value is equal to the population variance. However, the usual estimate of the population standard deviation, i. e., the square root of the sample variance is not an unbiased estimate. In this paper, various other estimators of the population variance are explored. Some of these estimators preserve the invariance property. Some examples are: Median unbiased estimator (divisor — n-5/3), modal unbiased estimator (divisor — n-3), minimum variance - minimum mean square error estimator (divisor — n+1), the method of moments and maximun likelihood estimator (divisor — n+1), uniformly most accurate unbiased estimator (divisor — n-1), etc. Furthermore, estimators in the sense of hypothesis testing properties and Bayesian estimators are also discussed. RANKING AND SELECTION: AN EXPOSITION TO NEW METHODOLOGY. S.N. Mishra, Dept, of Mathematics and Statistics, Univ. of So. Ala., Mobile, AL 36688. In today's complex world we are faced with the decision making in presence of uncertainties. Classical statistical procedures, such as testing and estimation with model building, have carefully provided analysis for many situations. However, the real situations at times demand for "choosing the best" in some sense. Ranking and selection procedures appropriately address this problem. Beginning with the pioneering works of Bechhofer (1954) and Gupta (1956), we are now in a position to answer some of the very basic questions left unanswered by the classical statistics. This paper is an attempt to give some of the existing important ranking and selection methodologies, and hence its nature is expository. A number of examples are included for discussion and a few very important literature citations are given . 158 Abstracts CALCULATION OF EFFECTIVE MASS AND PROBABILITY DENSITY USING A RECTANGULAR PERIODIC POTENTIAL: Abraham George, P.C. Sharma/ Department of Physics, Tuskegee University, AL-36088 A method of analysing the dynamic behavior of elec¬ trons for particular material is proposed by studying E-K relationship, effective mass and probability density. The schro dinger equation for the band electrons are solved and hence their probability density and effective mass for the first three energy states are estimated. Using a rectangular potential the calculations have been perform¬ ed that gives an insight to reinvestigate electron-energies in a system where the form, magnitude and period of the potential can be specified.

Harrison, B i rmingham , Birmingham, AL 35294. The embedded - cluster method [1,2], is distinguis from other cluster methods in that it uses Hamiltonian of an infinite system, matrix - represen in a basis limited to a finite number of "shells" atoms centered on the defect. The use of this method conjunction with the local spin density approximat (LSDA) of density functional theory has been applied F center in MgO.

Manocha, Department of Algebra, Combinatorics and Analysis, Auburn University AL 36849 A theorem is established which helps In obtaining symmetry algebra associated with the linear partial differential equation Qu ” 0, where Q is a differential operator. Guided by this theorem, a model of an irreducible representation D(a) of s£(2, €) on the representation space V with basis functions {^F^[a+n; y; x]ta+n: n**0 , +1, +2, ...} is constructed. Through Mellin transformation, which is duly introduced, this model induces another model of the representation D(a), in which the basis Q | n functions turn out to be {^F^Ia+n, B; y; x]t }. These models are 'exponentiated* leading to models of representations of the special linear group SL(2, C). By bringing into the scene the enveloping algebra of s2(2, e), this exercise eventually culminates in generating functions involving the hypergeometric functions F as well as F . SOME SPECIAL CLASSES OF MATRICES, Teh-Huey Chuang, Department of Mathematics, Tuskegee University, Tuskegee, Alabama 36088 For a given mxn matrix A, there is a matrix J. satisfying * + * + + A = AA and = A A, with A denoting the Moore-Penrose generalized inverse of A and JA the conjugate transpose of . We shall call a J-matrix of A. The concept of J matrices is used to develop three new classes of matrices called invariant matrices, JT invariant matrices and J-EP matrices. Necessary and sufficient conditions for the existence of these matrices are presented. Properties and relationships of these matrices are also investigated. All matrices considered are defined over the complex field. 160 Abstracts ROLE OF MTOs AND THE TAIL CANCELLATION IN CANONICAL BAND THEORY: A NEW APPROACH, P,C. Sharma, Department of Physics, Tuskegee University, Tuskegee, AL-36088 . The concept of canonical bands has been discussed which raises the LMTO method above the level of being just a new procedure for calculating energy-band structures. The important ingredients are volume and energy independent structure constants and parameters which contain information relating to the one electron-potential. It is shown that tail cancellation of MTOs give rise to highly simplified and physically transparent equation.

Russell, Department of Physical Sciences, Auburn University at Montgomery, Montgomery, AL 36193. Measurements of surface temperature were recorded for a heavily traveled roadway and an untraveled extension of the roadway of similar construction. Ten minute averages of traffic amount were also measured. Meteorological conditions during the observation periods were obtained from the National Weather Service. Traffic was found to enhance the transport of sensible heat from the roadway surface. The difference in temperature between the roadway and the untraveled extension was found to follow a simple relaxation equation. The dependence of sensible heat transport on traffic amount and the time constant for the return of the roadway to its untraveled state were estimated. This work was supported by the Research Grant-In-Aid Program of Auburn University at Montgomery, 161 Abstracts INDUSTRY AND ECONOMICS INTERNATIONAL MARKETING IN HUNTSVILLE, ALABAMA. Marsha D. Griffin and James G. Alexander, Departments of Marketing and Economics and Finance, respectively, Alabama A&M University, Normal, AL 35762. In the Fall of 1987, managers of 30/81 firms— designated as exporters in the HUNTSVILLE/MADISON COUNTY INDUSTRIAL DIRECTORY— were interviewed to determine the extent of their involvement in international marketing. About 37 percent of the sample had been involved in international marketing for over 10 years; about 34 percent had been involved between 1 and 5 years. For about 56 percent of the sample, foreign markets accounted for less than 10 percent of total annual sales. When asked if they changed the product, promotion, price, and/or distribution strategy for the international market, the percent responding "no" was 70, 53, 53, and 56, respectively. The percent indicating that they were unfamiliar with the Alabama Export Council, Alabama International Trade Center, Foreign Credit Insurance Association, International Trade Development Program, International Trade Specialist of the U. S. Chamber of Commerce, and the North Alabama International Trade Association was 36, 26, 63, 56, and 33, respectively. Problems with international marketing included finding customers, pricing, getting help for international marketing, export licensing, trying to keep technology away from the Soviet Union, communicating, identifying reliable distributors, modifying advertising , complying with paperwork requirements * collecting accounts receivable, fluctuating exchange rates, weakening of oil-dependent countries, dealing with cultural differences, and shipping. Respondents had entered foreign markets by indirect exporting, direct exporting, licensing, contract manufacturing, management contracting, joint-venturing, and direct investing. Of these entry strategies, the one most frequently used was direct exporting. FAIRHOPE, ALABAMA: A SINGLE TAX EXPERIMENT. Edward T. Merkel and G. T. Stewart, Troy State Univ., Troy, AL 36082 Since the turn of the century, Fairhope, Alabama has been the site of a laboratory experiment of Henry George's single tax. The Fairhope Single Tax Corporation (FSTC) has attempted to apply the theory that government can be financed solely by a single tax on land site value. The founder of FSTC hoped that this experiment would provide a stimulus to the adoption of the single tax by governments. The purpose of this paper is to discover and critically examine the views of the people in Fairhope on the claims made for and against the FSTC. The primary instrument used in the research is a random telephone survey of 110 Fairhope residents. Additional information was provided by interviews of FSTC officials, state and local tax accessors, and an analysis of the official records of the corporation. Part II analyzes and summarizes the results of the survey. Part III concludes that the majority of Fairhope residents do not believe that the FSTC has been beneficial to the community. 162 Abstracts TRADE AREA IDENTIFICATION FOR FACTORY-OUTLET SHOPPING CENTERS. Kerry P. Gatlin and Keith Absher, Dept, of Marketing and Management, Univ. of North Alabama, Florence, A1 35630 Shoppers at the regional factory-outlet shopping center in Boaz, Alabama were surveyed to identify point-of-origin, spending patterns, and perception of the center's drawing appeal. Reilly's Law of Retail Gravitation was tested to determine if the model could predict approximate trade-area boundaries for a regional specialty factory- outlet center. A modification of the model, using center size rather than community population was found to correctly locate 88 percent of trade-area shoppers. The relationship between distance traveled to the center and annual spending was found to be curvilinear. The appeal of the center was found to be selection, price and quality, in that order. The rural center's 'shopping mass' was found to overcome more dispersed discount opportunities in much larger metropolitan areas confirming the role that 'mass' plays in shopper gravitation. MINIMUM WAGE, UNEMPLOYMENT RATE AND THE CONSUMER PRICE INDEX - PRELIMINARY OBSERVATIONS. Stephanie Moxley Moore, Graduate Student, University of North Alabama, Florence, AL 35630. Stephanie Moxley Moore aftd Veronica Free, Professor of Economics, University of North Alabama, Florence, AL 35630. Increasing the minimum wage has been a controversial topic since its inception in 1937 • The minimum wage was originally established to shift the distribution of income in favor of the lower income households. But the actual purchasing power of the dollar has continually eroded away as the consumer price index and the minimum wage rate rises. A $3.35 minimum wage rate was worth only $1.02 in 1986. The very people that the original minimum wage was set up for are the ones who are suffering the most now. Businesses are having to cut back and increase prices. The inflation rate continues to rise and the value of the dollar continues to fall. Each new increase in the minimum wage seems to falsely uplift the purchasing power and better the hourly salary. When in fact, it only feeds an unquenchable inflationary spiral and ends up lowering the already depressed poverty level. INFLATION EFFECTS ON THE AGE DISTRIBUTION OF WEALTH. R. Bruce Jones, Univ. Of North Ala., Florence, AL 35632-0001 The maintenance of stable prices has been a policy objective of generations of economist. Many have argued against inflation on equity grounds. Often overlooked is the wealth redistributional effect. Since the effect of redistribution of wealth is uneven in a society one could argue that some age groups would suffer more than others. Using panel data for the period 1977 to 1983 the author attempts to identify changes in wealth by age groups. Younger age groups are found to lose ground both in nominal and real terms. This is in defiance to Life-Cycle Theory predictions. The author concludes that inflation contributed to wealth inequality by age groups. 163 Abstracts MARKETING THE CLASSROOM. Frederick A. Viohl, Marketing Department, Troy State University, Troy, AL 36082. The lack of good management is the major problem facing many colleges and universities today. During the period from the end of World War II until the late 1960s colleges could afford to ignore many management problems. This was primarily due to the large numbers of "baby boom" students who wished to go to college. There were more students who wished to go to college than there was space for the colleges to accommodate. No matter how poorly a college was operated, it would still be filled with students each year - even if the food was abominable, the instruction irrelevant and boring and the staff aloof or surly. The admissions office could still maintain a waiting list and serve primarily as order takers for would be students. If bad errors were made in fiscal policy or planning, a government loan or grant could easily be secured to bail out the college for a few years, or the colleges, if private, could merge into the state university and secure ample additional funds. With the end of the baby boom, changes in government funding priorities, and student demands for more relevant education, the days of wine and roses were over for many colleges. In the more competitive environment of the late 1970s and the 1980s most colleges and universities have had to resort to improved management and marketing techniques. The 1990s will demand that the traditionally diffuse areas of admissions, public relations, development, and alumni affairs be integrated into a single matrix of marketing management. AN APPLICATION OF LEARNING CURVE MODELS TO ANALYZING COST VARIANCES. Rama R. Guttikonda, Dept, of Accounting and Finance, Auburn Univ. at Montgomery, AL 36193. The phenomenon of learning, which is more pronounced in highly labor intensive industries tends to decrease the incremental production cost as the cumulative output increases. This learning effect has some very important inplications which can lead to unwise decision making and poor cost controls. Variance analysis results in misleading analysis in efficiency variances. An awareness of the learning effect can lead to significant improvement in four functional areas of acccounting of the firm (reporting, budgeting, cost control, and capital budgeting) where it is often overlooked. In the past few years, learning has been considered in managerial planning analysis such as product pricing, profit and cash planning, production scheduling, and break even analysis. Of late, attention has also been directed to the effect of Learning on managerial control of operations. The potential benefits of learning on managerial planning and control of operations are numerous. 164 Abstracts SHIITAKE MUSHROOMS: MARKETING PROBLEMS FACING THE SMALL FARMER. W. Joe Free, Tennessee Valley Authority, Muscle Shoals, AL 35660. William S . Stewart, Gerald L. Crawford and Veronica A. Free, Univ. of North Ala., Florence, AL 35632. The U.S. mushroom industry has grown at a 10 percent annual rate since the mid-1960s. Mushrooms produced in the U.S. for canning have remained relatively stable and the expanded production has gone for fresh consumption. Imports of canned mushrooms have doubled in the last 10 years. The Agaricus bisporus or button mushroom is the primary type produced and consumed in the U.S. In the 1980s, the Letimus or Shiitake has expanded rapidly but remains an "exotic" in the mushroom trade. Several button mushroom producers have added controlled environment facilities for producing Shiitake mushrooms and have added Oyster mushrooms to their product line. Many new Shiitake growers produce in the open and supplies are intermittent. Producers of mushrooms face buyers that control large volumes of product and they are changing to service the diverse requirements of these buyers. The small new Shiitake growers will face a major marketing dilemma. They will have to remain small and service a small local trade or band together and expand so they can meet the requirements of the commercial buyer. Consumption of mushrooms will continue to expand. The exotics such as Shiitake and Oyster will gain in popularity as consumers learn how to integrate them into their diets and as supplies become available year round. MEDIA AND AGENCY EXECUTIVES' PERCEPTIONS OF ADVERTISING MISTAKES KEITH ABSHER AND KERRY GATLIN, DEPT. OF MARKETING AND MANAGEMENT, UNIVERSITY OF NORTH ALABAMA. FLORENCE, ALABAMA 35630. This research used advertising professionals to rank the frequency and critical nature of advertising mistakes made by small businesses. A five point Likert scale questionnaire was developed from primary and secondary research on advertising mistakes. Advertising professionals were selected from advertising agencies, newspapers, radio stations, and television stations that are located in Alabama. The data from the questionnaire was broken down into a ranking by means of the top ten advertising mistakes of small businesses. The Top Ten Advertising Mistakes as ranked by advertising professionals are: 1. Not spending enough money to get results. 2. Not having a planned advertising budget. 3. Not advertising frequently enough. 4. Not taking advantage of co-op advertising money. 5. Lack of continuity. 6. Spreading the budget too thin. 7. Choosing a media based on its low rate. 8. Having no objective measure of advertising's effectiveness. 9. Not getting professional help for advertising. 10. Failure to pick a theme and live with it. 165 Abstracts AGRICULTURE IN ALABAMA BY THE YEAR 2000, James L^ Stallings and Rupert Hopkinson, Dept, of Agr. Economics and Rural Sociology, Auburn University, AL 36849-5406. From projections there is little doubt that the numbers of farms and land in farms in Alabama will continue to decline. Of the crop¬ land harvested, hay land is expected to at least remain steady or slightly increase. The beef industry, the main user of this hay land, is expected to continue present levels and increase to about a million cows by the year 2000. Soybeans will continue to be an important crop but will probably not soon reach the peak acreage of 2,150,000 of 1979. Instead, acreage is projected at about 560,000. This will produce about 12,880,000 bushels, an amount far short of the almost 41 million bushels crushed in Alabama plants in 1985, necessitating continued imports of soybeans if that level of crushing continues. Cotton has generally moved from the southern part of the State to the Tennessee Valley in recent years and the best estimate is that the recent decline in acres will level off and possibly increase slightly, Peanut acreage is projected at 230 thousand acres. Wheat and grain sorghum acreage should show increases by 2000. The broiler enterprise is expected to continue to expand and use large quantities of imported corn and soy¬ beans for soybean meal. Hens and pullets should also continue at a high level. Horses, mules, and ponies are hobby enterprises but significant users of grains and pasture resources and are expected to continue to expand. There is little doubt that the swine and dairy enterprises will continue to decline. CHAOS AND THE THEORY OF EFFICIENT MARKETS. Macon Wilbourn, Dept, of Accounting and Finance, Auburn Univ. at Montgomery, Montgomery, AL 36193. Sir Issac Newton, seventeenth-century physicist and mathemati¬ cian, Laid the scientific foundations of our modern world. Newton helped to separate scientific methodology from the mysticism of the dark ages, and formulated many of the tools necessary to understand¬ ing the workings of nature and the universe. Newton's followers, championed by the likes of Simon Laplace, believed that any system's behavior is predictable, given the prior knowledge of that system's initial conditions. Those things not predictable, such as the specified outcome of a coin toss, were subject to the laws of probability, and thus any desired outcome could be assigned a likelihood of occurrence. Efficient market theorists place stock market forecasting in this latter category. Both fundamental and technical analysis are believed to be ineffective as predictive tools for market behavior. But now the emerging science of Chaos is offering new insights into general systems behavior. Both Laplacian determinism and many probabilistic situations are yielding to the new "Laws" of Chaos Theory. The objective of this paper is to look at Chaos as it relates to stock market patterns and the theory of efficient markets. 166 Abstracts EXCHANGE RATES AND ECONOMIC NEWS. Charles E. Hegji, Dept, of Economics Auburn Univ. at Montg. , Montgomery, AL 36193. This paper investigates exchange rate and interest rate responses to the monthly U.S. merchandise trade announcements, focusing on the post 1985 period. The investigation demonstrates a significant exchange rate depreciation to larger than expected announcements. This result dramatically contrasts with previously reported lack of exchange rate response over the pre-1985 period. The investigation also shows that interest rates did not respond to trade announcement surprises over the entire post 1985 period. However, for the trade announcements covering the 1985.3 to 1986.7 period, the analysis indicates a significant decrease in short term interest rates to larger than anticipated trade deficit announcements. This result is consistent with the view that during this period the Federal Reserve attempted to depreciate the dollar in order to narrow the trade gap. For trade announcements during the 1986.8 to 1988.7 period, short-term interest rates increased, although not significantly, with the announcement of large trade deficits. This result is consistent with market uncertainty about changing central bank foreign exchange objectives, or the changing informational content in trade announcements. Finally, the analysis found that long term interest rates increased with large deficit announcements after 1986.7 which is consistent with increasing inflationary expectations. ECONOMICS OF EDUCATIONAL INVESTMENT. Curtis M. Jolly and Palitha Muthukude, Dept, of Agricultural Economics and Rural Sociology, Auburn University, Auburn, AL 36849-5406. In this paper models based on the theory of human capital were evaluated to determine their appropriateness in ranking postsecondary educational investment decisions. Data from the U.S. Bureau of Labor Statistics: Occupational Outlook and from report of the National Postsecondary Student Aid Study were used to estimate net present values (NPV), internal rates of return (IRR) and net benefit investment ratios (NIBR) for alternative educational investments. Refined models based on the theory of human capital were appropriate to evaluate alternative post¬ secondary educational investments, but the NPV and IRR were not appropriate in ranking projects. The NIBR was the most suitable criterion for such evaluation. The decision to invest or not to invest in postsecondary education depended on individual choice and economic circumstance. 167 Abstracts CHANNEL REQUIREMENTS IN MARKETING FRESH FRUITS AND VEGETABLES. Gerald Crawford, Professor of Marketing, William S. Stewart, Professor of Management, and Joe Free, Professor of Economics, School of Business, University of North Alabama, Florence, AL 35632. Approximately two percent of all fresh fruits and vegetables are sold directly to ultimate consumers in the U.S.A. while 98 percent passes through indirect channels. In other countries significantly larger amounts are sold directly to consumers. It would be helpful if small farmers could learn why consumers buy the way they do, and to learn what marketing functions are required to move these farm products to consumers and organizational buyers. Available data provides evidence that American consumers want fresh produce at reasonable prices, and they want these products consistently available at their existing (one-stop) retailer. Consumers do not care to make special trips to buy produce unless large quantities for canning are being purchased. Organizational buyers want consistent availability of fresh, high quality produce from a small number of suppliers who call on the account and provide delivery and credit terms. In summary, small farmers must provide time and place utility, along with related services if they expect to compete with large farmers and corporate operations. TAX SIMPLIFICATION AND THE COST OF TAX COMPLIANCE. Samuel L. Lett, Dept, of Accounting and Finance, Auburn Univ. at Montgomery, AL 36193. Tax simplification was one of the driving forces behind the passage of the massive Tax Reform Act of 1986 (TRA). The perception held by taxpayers that the tax law was unduly complicated and unfair was used by supporters of tax revision in Congress to generate the passage of the TRA. The TRA hailed as tax simplification at the time of its passage has created far greater complexity and costlier tax compliance for taxpayers than previous tax laws. Even with the removal of approximately six million taxpayers from the tax rolls due to lower tax rates, still nearly fifty percent of taxpayers pay professional tax preparers to complete their returns. Based on figures provided by the Internal Revenue Service (IRA), the cost of a return could be greater than a thousand dollars. Additionally, evidence exists that major mistakes by preparers costing taxpayers thousands of dollars do occur at at all levels of professional tax preparation. An analysis of IRS time estimates for preparation of federal tax forms reveals that while these estimates may be overstated, taxpayers can expect to pay more for return preparation. The tax simplification hoped for has generated major cost increases for tax compliance by the taxpayer. 168 Abstracts SCIENCE EDUCATION LEARNING OF DRUG TERMINOLOGY BY BEGINNING BACCALAUREATE NURSING STUDENTS. Alfred E. Lupien and Ellen Buckner, School of Nursing, University of Alabama at Birmingham, Birmingham, AL 35294. The purposes of this study were to measure the change in drug terminology scores across the span of one academic quarter and to determine if relationships existed between terminolgy scores and various demographic characteristics. Fifty-eight nursing students enrolled in an introductory pharmacology course participated in the study which included completion of written examinations eight weeks apart, an investigator-developed semantic differential, and a demographic worksheet. The difference between scores at the beginning and at the end of the quarter was not statistically significant; nor were there statistically significant relationships between examination scores and age, self-reported percentage of terms previously known, or attitude toward knowledge of drug terminology. Relationships were demonstrated between terminology score and years of employment in health care (_r = -.328, £ = .009, n = 56) as well as between terminology examination score and final course grade (r_ = .616, £ = .001, £ = 58). Three conclusions may be drawn from the findings of this study: that scores on drug terminology examinations did not change across the span of one academic quarter, that there was a negative relationship between years of employment in health care and terminology examination scores, and that there was a strong relationship between examination scores and final course grade. Instructor-related interventions that may facilitate learning of terminology include assuring that terminology is consistent with contemporary clinical language, conscientiously utilizing these terms in classroom instruction, and encouraging student use of terminology. COASTAL POLLUTION*- A REFLECTION OF GLOBAL DISASTER. John J. Dindo, Dauphin Island Sea Lab - Discovery Hall Project, Dauphin Island, AL 36528. For years we have heard about coastal pollution problems from around the world. No one could believe that an estuarine system as large as the Chesapeake Bay could collapse, yet it did and with very little warning. In the last six months the media within the U.S. has featured cover articles on our dying planet. Are these only stories that sell magazines and newspapers or do they reflect a real threat to mankind and our planet. 169 Abstracts NATURE'S WAY SERIES: A REPORT ON THE IMPLEMENTATION OF A PILOT SCIENCE ENRICHMENT PROJECT. Robert 0. Joslin, Center for Environmental Research and Service, Troy State University, Troy, Alabama 36082. The Science Education Enrichment Project was originally conceived by the Center for Environmental Research and Service and the Regional In-Service Education Center of Troy State University. The nature of the pilot program was designed to establish a 3-way partnership between Troy State University, the Troy City School System and the local business community. The purpose of this partnership arrangement was to develop and implement experience-based science activities that would enrich the existing curriculum of the participating target school. The project was successful in establishing an on-going science enrichment program at the target school. A product of this development and implementation is The Nature's Way Series: A Guide to Science Enrichment Activities. This published curriculum guide is serving as a valuable resource for science enrichment programs in public schools. TEACHING HANDICAPPED STUDENTS SELECTED CONCEPTS ABOUT RADON HAZARDS, Joseph D. George, Ernest D. Riggsby, and E. Christopher Carlisle, Columbus College, Columh_u§, GA 31993-2399. Since there are two distinctly different approaches to the teaching of handicapped students: through mainstream¬ ing and in special classes, it was deemed desirable to prepare a mini-unit which would be compatible with either approach. The project approached radon as a significant health hazard, probed its origins, its nature, how it might be detected and its concentrations determined. Visual, verbal, and tactile experiences were devised. A major objective was to help develop a keen awareness of the presence of radon in our environment but without developing anxiety. The culmination of the mini-unit was the demonstration of testing equipment and a discussion of measures to be taken if a screening test indicated higher than normal, tolerable levels. 170 Abstracts Of Wolves and This Woman. Nancy V. Veil, Teacher-In-Residence, Ala. Power Company , ^Birmingham Al. 35291. Dr. Lugi Boitani, University of Rome, Dr. Francisco Francisci, National Institute of Game CBiology , Rome, Italy. Legend tells of how Romulus and Remus were suckled and nourished by a she wolf. Romulus went on to found the city of Rome in Ttaly. A latin proverb warns Homi homini lupus: Man is a wolf to man. This proverb proved to be the foundation of a current feeling in Rome and inother parts of Italy about people who dare to study the now almost extinct wolf. "Of Wolves and This Woman", is represent¬ ative of the research which I did in conjunction with an ongoing research project on wolves in the Appentine Mountain chain in Italy to determine the number of wolves left. The research seeks to find the reasons for near extinction by studying geographical range, feed¬ ing, and mating habits of the Italian wolf and the feral dog packs of the Appenines. Specific information obtained was a) ascess to what extent, given the same environmental conditions, wolf and dog develop survival strategies b) ascess degree and mode of competition between wolf and dog c) ascess to what extent survival of feral dog packs is done to recruitment of adult stray dogs from outside the packs d) ascess preying on the study area livestock e) ascess how certain environmental changes may limit and/or enhance survival of wolf and/or dog. IMPACT OF THE ALABAMA ACADEMY OF SCIENCE VISITING SCIENTIST PROGRAM ON STUDENT ATTITUDES. Robert E. Hayes, Tallassee High School, Tallassee, AL 36078 The purpose of this study was to review the scope of the AAS Visiting Scientist program and to examine the impact of a visiting scientist on student attitudes and knowledge about recombinant DNA at Tallassee High School. Pretests and posttests were administered to 136 students to assess knowledge about DNA and recombinant DNA technology before and after a visit from a visiting professor from Auburn University. Student attitudes toward various ethical aspects of recombinant DNA technology were also assessed. After the scientist's talk, student knowledge increased 10% when measured six months later. Students attitudes remained relatively stable over the six months period and generally reflected views held by a majority of Americans. Student? opposed any use of the technology for achieving the "perfect" human but favored use of cloning for achieving better crop yields and in the search for cures for intractable diseases. Students gained both longterm knowledge and a better appreciation of how working scientists solve problems from the Visiting Scientist program. 171 Abstracts RADON-222: A CONCERN FOR MIDDLE SCHOOL SCIENCE. Ernest D. Riggsby , Joseph D. George, and E. Christopher Carlisle, Columbus College, Columbus, GA 32993-2399. School science courses allow some flexibility in the selection of topics. This paper describes a unit on radon, its physical and chemical properties, how it originates, and how it is detected and mitigated. This study of radon adapts well to physics, chemistry, physical science or biology. Since the Environmental Protection Agency made its announcements about the hazards of radon, there has been an increasing presence of door-to-door salespersons, offering testing and mitigation at prices which are often much too high. This scare tactic can probably best be countered by education. This effort was aimed at raising the awareness level, as well as, the informing of students, with the parallel anticipation that some of the information and handouts would find their way into the hands of the parents of some of the students, and suggest proper and much less expensive measures for detecting and measuring radon levels in the indoor-environment. THE MANAGEMENT OF HAZARDOUS SUBSTANCES ON SMALL-COLLEGE CAMPUSES. Ronald N. Hunsinger and W. Mike Howell, Dept, of Biology, Samford Uni¬ versity, Birmingham, AL 35229. Due to new federal regulations designed to inform employees of potential hazards in their workplace, colleges and universities must begin to revise their policies and procedures governing the procurement, proper usuage, and storage of hazardous material. Such "Right-to-Know" legislation calls for written compliances from institutions regarding detailed hazardous substances inventories, material safety data sheet compilation and availability, and documentable employee safety training. Additionally, a strengthening of the Hazardous and Solid Waste Amend¬ ments (HSWA) and the Resource Conservation and Recovery Act (RCRA) man¬ dates a radically different approach for the disposal of materials designated as hazardous and regulated according to RCRA and HSWA. Fail¬ ure to comply with these regulations can result in imprisonment, fine up to $25,000, and civil suits by any citizen harmed as the result of negligent use or disposal of hazardous material. In light of these re¬ cent developments, it is in the best interest of colleges and universi¬ ties to devise appropriate policies which address the issues mentioned above. This presentation will provide a model for compliance, designed especially for small colleges and universities. 172 Abstracts SOCIAL SCIENCES CORRELATES OF COMPUTER-RELATED STRESS. Richard A. Hudiburg, Dept, of Psychology, University of North Alabama, Florence, AL 35632 The purpose of this study was two-fold. First, the reliability and construct validity of the Computer Technology Hassles Scale (CTHS) , a measure of computer-related stress, was determined. Second, correlates to this measure of computer-related stress were investigated The Computer Technology Hassles Scale (CTHS) was composed of 69 "hassles" or potential computer technology stressors . A questionnaire was constructed that included demographic information, the CTHS, the Perceived Stress Scale (PSS), a global measure of stress; the Computer Attitude Scale (CAS), and the semantic complaint items from the Hopkins Symptom Checklist (HSCL) . The questionnaire was administered to a sample (N - 129) of undergraduate students. A second administration of the questionnaire, which included an additional measure, the Computer Anxiety Scale (CAXS), was given two months later to the same sample of students. A total of 100 students responded to both administrations of the questionnaire. Reliability analysis indicated that the CTHS had a moderate test- retest reliability coefficient (r = .64). Correlation analysis indicated that the CTHS, as a measure of computer-related stress, was significantly correlated to perceived stress (PSS) and semantic complaints (HSCL) . The CTHS was independent of attitudes toward computers (CAS) and computer anxiety (CAXS). A principal axis analysis with varimax rotation of the items composing the CTHS yielded 11 factors. A scaling analysis of the 11 factors revealed that nine defined subscales of the CTHS met minimum internal consistency requirements. The current research indicated that the CTHS was a reliable and construct valid measure of computer-related stress. BIPARTISAN1IAT1QN OF THE BLACK ELECTORATE; THE CASE FOR THE SYNTHETIC EQUAL OPPORTUNITY POSTURE. Lawrence J. Hanks, Department of Political Science, Tuskegee University, Tuskegee, AL 36Q8B The black electorate is the Democratic Party's most loyal voting bloc. Since joining the New Deal coalition in 1936, a majority of the black electorate has supported the Democratic ticket for the presidency Since I960, an overwhelming majority of the black electorate has supported the Democratic ticket. This loyal support has had two major effects; the Democrats take the black electorate for granted while the Republicans ignore it. This paper argues that the black electorate should adopt the synthetic equal opportunity posture to combat the forestated negative effects. This position argues that political effectiveness dictates a 40% black yellow-dog Republican base, a 40% black yellow-dog Democratic base, and a 20% Independent base which is capable of mobilizing behind the desired candidate. Others options are examined and the synthetic equal opportunity posture is defended as the optimal posture for political effectiveness. 173 Abstracts ANALYSIS OF DINOSAURS: POLICE ORGANIZATIONS AND CULTURE.

Dept, of Crimino¬ logy and Criminal Justice, Alabama State University, Montgomery, Alabama 36195 This paper examines police organizations to determine the common charactertistics that they share based on various organizational theories and the unique culture that exists within such organizations. A brief history of police organizations is presented, along with pertinent organizational theories, principles, and cultural characteristics which influence the structure and opera¬ tion of police agencies. Specifically, police organiza¬ tion and culture were analyzed; the authors conclude that the traditional police organization and culture are like dinosaurs in terms of efficiency and the role that police are expected to play. ROLE OF THE PRESIDENT AS PERCEIVED BY CHILDREN. Sheila Davis and Cora A. Ingram, School of Nursing, University of Alabama at Birmingham, Birmingham, Alabama 35294. Fran Perkins, School of Education, University of Alabama at Birmingham, Birmingham, Alabama 35294. The study was conducted to determine the perceptions of selected children of the role of the President of the United States of America. Twenty-six children were interviewed utilizing a semi-structured interview guide. The respondents were drawn from a convenience sample at three different sites in Birmingham, Alabama. The data were analyzed by the process of enumeration and domaining. The study revealed that these children perceived the role of the President as leader and peacemaker. They also viewed his job as one requiring higher education and providing substantial monetary reward. HOUSING THE MENTALLY ILL IN URBAN COMMUNITIES. Jill Hall Dept, of Political Science and Public Affairs, Univ of Ala. at Birmingham, Birmingham, AL 35294. The need for appropriate housing for the chronically mentally ill has become an increasingly difficult problem to resolve in urban communities. In recognition of the need for more housing for the» mentally ill more organizations are turning to the HUD Section 202 for a partial resolution to the problem. The Birmingham area is no exception either in problem or prospective solution. A look at the implementation process of a Section 202 program in the Birmingham area reveals some local and national implications for the future of housing the mentally ill in urban communities. 174 Abstracts THE BLACK MALE IN ALABAMA: A DEMOGRAPHIC PORTRAIT. Donald W. Bogie, Dept, of Demographic and Cultural Research, Auburn Univ. at Montgomery, Montgomery, AL 36193. William A. Barrett, Dept, of Human Resources, State of Alabama, Montgomery, AL 36130. Milton E. Belcher, Attorney General's Office, State of Alabama, Montgomery, AL 36130. Reversing a decline that had prevailed for three decades, the number of black males in the Alabama popu¬ lation registered a moderate increase during the 1970s. Still, however, this group comprised only 11.9 percent of the state's population in 1980, down from 17.3 percent a half century ago. Black males constitute an exceptionally youthful population, who overwhelmingly reside in metro¬ politan locales. While they remain most highly concen¬ trated in Black Belt counties (as measured by the number per 1,000 population), the largest totals by far reside in Jefferson, Mobile and Montgomery counties. Black males in Alabama are much more apt than their white counterparts to be absent from the family, to have fewer years of education, and to earn less. They are also more likely to be arrested than white males and to be characterized by higher rates of incarceration. Mortality rates are sig¬ nificantly higher for black males than for other segments of the population, while life expectancies at birth are correspondingly lower. Although not the total solution, an increased emphasis on education, job training, and occupational placement would serve to enhance the socioeconomic status of the black male. CgyMJNICATION APPREHENSION: REDUCTION WITHIN A PRISON SETTING. Eugenie Nickell, Del Witherspoon and Carolyn Long-Hall, Auburn University of Montgomery, Montgomery, AL 36193. This study compared self-reported ccnmunication apprehension (CA) experienced by female inmates before and after attending a special program within a state prison. Thirteen women volunteers who scored high on the Personal Report of Confidence As a Speaker (PKCS) (Paul, 1966) were ( treated in a program incorporating various techniques including systematic desensitization, cognitive restruc¬ turing, skills training and shaping within six two-hour sessions. Pre-post ccrrparisons resulted in a significant decrease in CA (t = 7.12, df=10, p< .001). Discussion focused on basic character¬ istics relevant to this population (short attention span and low reading level) and restrictions of an institutional nature such as excessive noise levels, lack of privacy and limitations on possession of study materials. 175 Abstracts AN INTERACTION PROCESS ANALYSIS OF COLLABORATIVE WRITING. Annete N. Shelby, School of Business Communication, Georgetown Univ. , Washington, D.C. 20057. Amanda W. Borden, Dept, of Theatre, Birmingham-Southern College, Birmingham, AL 35254. Collaborative writing involves two processes: (1) writing, which within the accepted recursive view includes prewriting, drafting, and editing; and (2) interaction, which involves intrapersonal and inter¬ personal processes. The present research focused on interpersonal processes as they relate to the task of collaborative writing. The research question was this : In what way do interaction and writing processes influence efficiency, effectiveness, and satisfaction (mea¬ sures of collaborative writing)? To test the research question, the researchers studied six work groups comprised of graduate business students. Coders evaluated audio tapes of the group discussions according to the Interaction Process Analysis system [Bales, R.F. (1959) Interaction process analysis : A method of the study of small groups . Cambridge, MA: Addison-Wesley . ] The findings were as fol¬ lows: (1) The more structured the group process, the more efficient the prewriting stage; (2) Efficiency of the process was greater when tasks to be accomplished were identified early in the prewriting process, when a strong leader emerged, and when one individual (as opposed to a number of group members) revised and edited the document; (3) The group product was more effective when the group process was highly structured, when more time was allotted to revision and editing, and when group members participated in revising and editing; and (4) Individuals experienced greater satisfaction when they perceived all group members to have "carried their weight." ADOLESCENT SELF PERCEPTIONS: AN EXPOSITION BASED ON PERSONAL INTERVIEWS. Kasandra E. Williams and Jan 0. Case, Department of Mathematics and Statistics, Samford University, Birmingham, AL 35229. A self-reporting questionnaire and the Bern Sex Role Inventory were used to evaluate adolescent self perceptions on such traits as androgyny, self esteem, sexual activity, and perceived sexual pressures. Ninety-one adolescents with primarily white middle class backgrounds were found to perceive themselves as androgynous, with no difference in male and female ratings. Differences occurred among males and females with respect to self esteem ratings, with females assigning themselves lower ratings. Among females, self esteem was also found to be dependent on sexual activity, with sexually active females rating their self esteem lower than non-sexually active females. Both males and females felt that their sexual activity was not influenced by pressure to be sexually active. 176 Abstracts College Education Among Police Officers of Selected Alabama Law Enforcement Agencies. Tim Jones , Dept, of Justice Studies, Athens State College., Athens, AL 35611. Jerry Armor, Dept, of Criminal Justice, Calhoun Community College., Decatur, AL 35601. In recent years there have been significant increases in the educational levels of the American workforce, and there has been a perceived need for advanced education for police officers. In response to the 1973 National Advisory Commission on Criminal Justice Standards and Goals that all police officers should possess an under¬ graduate degree by 1983, an examination of the current status of higher education among police in Alabama is needed. The purpose of this descriptive study is to determine the level of college education among police officers from selected agencies in Alabama, and to com¬ pare the results with national averages. Nine Alabama municipal police agencies were surveyed in order to determine the percentage of officers possessing two years of college, two to three years of col¬ lege, and four or more years of college education. The results of the analysis revealed that selected police agencies in Alabama range from a high of 85% of officers possessing college credits (exceeding the 78% national average) to a low of 31%. The study has definite impli¬ cations for additional research. The research study has attempted' to construct baseline data for future comparisons of higher education among police officers, but correlations of percentage of college edu¬ cated police officers with jurisdiction size, educational pay incen¬ tives, agency proximity to educational institutions, and educational levels among supervisory ranks remain to be studied. Accreditation of Criminal Justice Education Programs: Is There A Need? Joseph Luskin, Dept, of Criminal Justice, Alabama State University. Accreditation for postsecondary educational programs in criminal justice has been a controversial issue among criminal justice educators for more than a decade. The development of accreditation, in general, is a distinctive characteristic of American education. The develop¬ ment of a good accreditation procedure in criminal justice however, has been unsuccessful over the years because of certain major areas of diverse opinions within the profession. As a consequence, there are polarized schools of thought as to whether or not criminal justice, as presently taught in degree awarding universities, should be under the aegis of an accreditating agency. Following a brief historical treat¬ ment of accreditation in the United States, this paper explores some of the pros and cons, the advantages and disadvantages of accredit¬ ation. The purpose of this paper is not to extol the virtues of either of the extreme positions over the other but rather to set the scene for a mutual philosophically oriented arena wherein a meeting of the minds may be accomplished. The position taken is that a profession requires its practitioners to conform to certain minimum standards of acceptance and that by voluntary participation in a universally recognized and respected accreditation agency, this objective can be accomplished 177 Abstracts REPERCUSSIONS OF ACCEPTANCE OF CRIME MYTHS ON INDIVIDUAL FEAR OF CRIME. Mark M. Lanier, Dept, of Criminal Justice, University of Alabama at Birmingham, University Station, Birmingham, AL. 35294. Crime myths are widespread in our society. Sociologists, criminologists, and other theorists have established the existence of these myths and have postulated as to their function. This study contributes to our understanding of the impact of crime myths by focusing on the repercussions of these myths on attitudes. The focus of this research is on whether or not an unsubstantiated, exaggerated perception of crime precipitates a heightened fear of crime. Media attention has been focused on the 'crime problem' and a 'fear of crime' which reputedly exists among students attending the University of Alabama at Birmingham. One hundred fifty randomly selected university students were surveyed to measure an acceptance of myths and a fear of crime. Relationships were found to exist; myths are accepted and are positively related to an increased fear of crime. In addition, the visual mass media was eliminated as being a primary source of common crime myths--it is generally recognized as being unrealistic. RECENT RESEARCH WITH THE FAMOUS SAYINGS TEST. Charles EL_ Joubert, Dept, of Psychology, University of North Alabama, Florence, AL 35632 Bass's Famous Sayings Test contains four scales derived through factor analysis: Conventional Mores, Hostility, Fear of Failure, and Social Acquiescence. The purpose of this research was to assess the presence of these traits in north Alabama and to compare locally observed norms with those of the original standardization group. An additional purpose was to determine the stability of these local norms over a fifteen-year period. Two samples of university students responded to the Famous Sayings test. The 1973 sample consisted of 29 men and 50 women; while the 1988 sample consisted of 31 men and 54 women. The results indicated that women scored higher than did men on Conventional Mores and Social Acquiescence, with no significant sex differences being observed on Hostility and Fear of Failure. No sig¬ nificant changes occurred on any of the four scales between 1973 and 1988. When compared against the original standardization group, north Alabama women's means were higher on both Conventional Mores and Social Acquiescence in both 1973 and 1988; and higher on Hostility and Fear of Failure in 1988 only. Men's means on these scales compared with those of the original standardization group, with the exception of higher Hostility means in 1973. Finally, the Social Acquiescence scale correlated positively with Conventional Mores and Fear of Failure for both sexes and in both yearly samples. Hostility posi¬ tively correlated with Fear of Failure and Social Acquiescence scores in women. 178 Abstracts POLICE OFFICER FEMINIST ATTITUDES AND PERCEPTIONS OF FEMALE CRIME: AN EXPLORATORY ANALYSIS. John J. Sloan , Dept, of Criminal Justice, Univ. of Ala. -Birmingham, Birmingham, AL 35294. Criminologists have recently become interested in the extent and nature of female criminality. Most of this research has examined changes in female arrest trends over time using official sources of data. Less well researched is the area of the attitudes and percep¬ tions of criminal justice officials regarding female criminality, i.e. do criminal justice officials believe female criminality has changed and react to women suspects based on these beliefs? This study, using a sample of police officers from Indiana, analyzes links between po¬ lice officer feminist attitudes and officer perceptions of female criminality. The results indicate that officers generally hold strong anti-feminist views concerning women in work, politics, domestic matters and social matters, as well as that officers perceive female involvement in crime as more prevalent than previously, that female offenders are perceived as being more violent than before, and that the women's movement is partly responsible for the changing nature of female criminality. Officer perceptions of female offenders are in agreement with Adler's (1976) depiction of a "new female criminal". Explanations for these results are considered from two sources: organizational socialization into police work and occupational choice bringing together like minded individuals. VERTICAL AND HORIZONTAL PROSECUTION: ADVANTAGES AND DISADVANTAGES FROM THE PERSPECTIVE OF THE VICTIM. William E. Osterhoff, Dept, of Justice and Public Safety, Auburn Univ. at Montgomery, Montgomery, AL 36193. The role of the prosecutor In the American criminal Justice systems results In a combin¬ ation of quasl-Judlclal and political power which Is derived, In part, from his/her potential Involvement In almost every stage of the criminal Justice system process. The prosecutor, as a representative of the state and the criminal Justice system, has the responsibility of assuring that Justice occurs within the criminal justice system. The prosecutor's goals also Include obtaining convictions of guilty defendants and protecting the rights and Interests of the victims whose cooperation Is needed for successful prose¬ cution of offenders. Two models by which prosecutors can manage their caseloads are vertical and horizontal prosecution. In vertical prosecution, one prosecutor handles a case at all stages of the proceedings, whereas In horizontal prosecution, different prosecutors handle the various stages of the proceedings. For victims of violent crimes such as child abuse and rape, vertical prosecution offers several advantages over horizon¬ tal prosecution. The victim Is not forced to repeat the details of the criminal act to different prosecutors at each stage of the criminal Justice process. Because of the one- to-one relationship with the prosecutor, the victim Is provided with more continuity and Is more likely to have Input Into each stage of the criminal Justice process. Vertical prosecution also benefits witnesses and professionals who might testify on behalf of the victim. Disadvantages of vertical prosecution result when there Is rapid turnover In staff In the prosecutor's office and when the prosecutor who Is assigned to a victim Is Inexperienced or less than optimally competent. 179 Abstracts HEALTH SCIENCES ANALYSIS OF A SURFACE PROTEIN FROM A PspA (PNEUMOCOCCAL SURFACE PROTEIN A) MUTANT. Timothy E. Hughes and Larry S. McDaniel. University of Alabama at Birmingham, Birmingham, AL 35294. PspA was originally identified using monoclonal antibodies that can protect mice against intravenous challenge with several strains of Streptococcus pneumoniae. We previously reported on the isolation of insertionally inactivated mutants of strain Rxl which fail to express this cell surface protein. In analyzing other cell wall components that can elicit protective responses, we have produced a hybridoma cell line, designated SC25, that secretes an IgM, k antibody which reacts with a non-PspA pneumococcal surface protein. SC25 was generated from a CBA/N mouse that was immunized with a protection eliciting gel filtration fraction of cell wall material from a PspA mutant. By Western blotting this antibody detects a broad range of molecular weight bands in a single pneumococcal isolate. Not unlike some monoclonal antibodies against PspA, this antibody fails to protect mice against pneumococcal challenge. We have identified clones in a Xgtll expression library of genomic pneumococcal DNA that react with this monoclonal antibody. We are characterizing these clones to assess the ability of this protein to elicit protection against pneumococcal infection in mice. SANDPLAY THERAPY. Frances Gatewood, School of Nursing, University of Alabama at Birmingham, Birmingham, AL 35294. Sandplay is a psychotherapeutic modality in which clients create three dimensional scenes, pictures or abstract designs with sand, water and a large number of miniature realistic figures. It can take place with few or no words and change is experienced and observed in behavior. Sandplay is based on the postulate that the psyche contains a drive toward wholeness and health. This drive toward realization of potential, suggests that the psyche, like the body, under adequate circumstances, has a tendency to heal itself. Sandplay provides a "free and protected space" for this to happen and a br-idge between inner and outer life. 180 Abstracts Axillary Versus Rectal Temperatures in Children Under Four Years of Age J. Colleen Russell. Captain, Army Nurse Corps, Pediatric Nurse Practi¬ tioner, Graduate Student, University of Alabama at Birmingham. Abstracts This descriptive study was designed to ascertain if there was a significant difference between axillary and rectal temperature measurements in children under 4 years of age. Instruments utilized were an investigator constructed demographic tool and 2 glass thermo¬ meters (one rectal and one oral thermometer). (Results supported cur¬ rent literature). Although a paired differences t test revealed a sig¬ nificant statistical difference between the two measurements , the mean temperatures of 9 8.52° F for axillary temperatures and 99-21° F for rectal temperatures are statistically correlated. Therefore, it is not clinically significant to warrant the discomfort and risk of physical insult caused tjy rectal temperature measurements. Recommendations for future research include: (a) repeat of study changing thermometer placement times to 3 minutes for rectal temperatures and 5 minutes for axillary temperatures, (b) repeat of study in children with febrile episodes versus healthy children, (c) study the differences in morning versus afternoon temperatures in the same subjects.

NUTRASWEET: A COMPARISON OF CONSUMPTION LEVELS OF COLLEGE STUDENTS WITH THE UNITED STATES GENERAL POPULATION. Mary-Martin Nordness and Jan Case, Department of Mathematics and Statistics, Samford University, Birmingham, AL 35229. A review of related research concerning the consumption of NutraSweet, as well as phosphorus and caffeine, is presented with emphasis on studies concerning females. National per capita figures from the U. S. Department of Agriculture are used as a basis for evaluating the consumption levels of 105 Samford University students who answered a questionnaire prepared by the authors . 181 Abstracts USING MAGNITUDE ESTIMATION SCALING TO EXAMINE THE VALIDITY OF NURSING DIAGNOSIS. Joan S, Grant, School of Nursing, University of Alabama at Birmingham, University Station, Birmingham, Alabama 35294 This descriptive exploratory study was guided by a diagnostic reasoning framework and used magnitude estimation scaling (MES) to examine the construct validity of the nursing diagnoses altered level of conscious¬ ness: arousal and altered level of consciousness: content. I) What are critical defining characteristics? 2) What are important defining characteristics? 3) What are clinical manifestations? MES is a techni¬ que in which numbers are assigned to stimuli in proportion to the magnitude of subjective responses. Thirty nurse subjects scored the importance and frequency of defining characteristic in confirming both diagnoses. Critical defining characteristics for altered level of consciousness: arousal were no motor response to painful stimuli, no brainstem reflex activity, abnormal extension posturing, abnormal flexion posturing, fixed eye position, no motor response. . .auditory stimuli, and diminished brainstem reflex activity. The correlation between the geometric means of the defining characteristics for impor¬ tance and frequency was not significant (£=-.19, £=.32). Critical defining characteristics for altered level of consciousness: content were inappropriate behavior, incomprehensible speech, only obeys one- step commands, inappropriate speech, and impaired recent memory. There was a significant relationship between the geometric means of the defining characteristics for importance and frequency for altered level of consciousness: content (£=.62, £=.001). There was support for con¬ struct validity of the nursing diagnoses. MES was a useful technique for examining the construct validity of both nursing diagnoses.

Ware, Dept, of Family Medicine, Univ. of Alabama, Tuscaloosa, AL 35487. The spread of HIV infection in Alabama continues to escalate. The distribution of the disease, however, is not strictly confined to the major metropolitan areas (population greater than 100,000). According to the AIDS update compiled by the Alabama Department of Health, as of February 1989, there have been 476 cases of AIDS reported. Of interest is the fact that of those counties with a population of less that 50,000, 12 counties have no cases diagnosed and the rate per 100,000 ranges from 2.6 to 33. For the population between 50-100,000 the rate is from 1.7-14.5, and for the counties with a population greater than 100,000 the rate is from 1.9-23.2. This comparison of the range of the rate per hundred thousand and population per county suggests there are a significant number of HIV infections in the rural population. 182 Abstracts STRESSORS, LEVELS OF STRESS, AND SELF-CARE ACTIONS TO REDUCE STRESS IN PREADOLESCENT CHILDREN. Linda Roberts, Dept, of Nursing, North Georgia College, Dahlonega, Georgia 30597. The purpose of this study was to ascertain gender-related stressors, levels of stress, and self-care actions for reducing stress in preadolescent children; and to ascertain if there were differences between mothers' perceptions and children's perceptions of the same variables. Orem's (1985) Self-Care Nursing Model and concepts related to stress were the framework guiding the study. An exploratory/ descriptive design was used to collect data from 64 preadolescent subjects and their mothers, using three research instruments. Descriptive, Chi-square, and t-test analyses of data revealed the following findings: (a) "fighting with sibling(s)" was the most frequently occurring stressor; (b) stress levels in the majority of children were average; (c) "trying to forget about it" was the most common self-care action used by children to reduce stress; (d) participation in organized activities, talking to parents, and interaction with others as well as pets were mentioned by the child subjects as helpful in reducing stress; (e) mothers identified similar stressors and self-care actions to reduce stress as their children, but mentioned stressors related to school problems more often than the child subjects; (f) there were no statistically significant differences between the child subjects' levels of stress and the levels of stress as perceived by mothers; (g) there was a statistically significant association between mothers talking to children directly about how to manage stress and the child subjects' levels of stress; (h) there were few gender-related differences in stressors, levels of stress, and self-care actions to reduce stress. PRIMARY PERITONITIS: CASE REPORT AND LITERATURE REVIEW. Todd Sherrer and Robert E. Pieroni, College of Community Health Sciences, Univ. of Ala., Tuscaloosa, AL 35487. Primary peritonitis is an inflammatory process of the peritoneal cavity with no documented source of contamination such as a perfo¬ rated viscus or penetrating injury. Alcoholic liver disease and ascites are major predisposing factors to primary peritonitis in adults. This disorder can present with minimal peritoneal signs and the clinical picture is often dominated by a more obvious problem. The significant mortality rate and subtle presentation mandate that the clinician have a high index of suspicion in the predisposed population. The characteri sties of primary peritonitis will be discussed and a typical case which emphasizes many of the features of this often unrecognized disorder will be presented. 183 Abstracts COMPARISONS OF DUBOWITZ SCORES OF NEWBORN INFANTS AT 2, 12, and 24 HOURS AFTER BIRTH. Penne Mott , Graduate Study, University of Alabama School of Nursing, Birmingham, AL 35294. Assessing the gestational age of the newborn infant is a routine practice of neonatal health care providers. When used in combination with the infant's weight, determinations can be made about the infant's size for gestational age. The clinical care provided to an infant is often based on knowledge acquired from these parameters. Utilizing the Dubowitz scoring system of assessment for gestational age, assessments can be performed anytime up to 5 days after birth. Research substanti¬ ating the accuracy of these scores at different time periods post- delivery is lacking. The purpose of this study was to ascertain if there were statistically significant differences in the Dubowitz scores of newborn infants at 2, 12, and 24 hours after birth. The study popu¬ lation consisted of 24 full-term neonates that were products of spon¬ taneous, low forceps vaginal, and cesarean section deliveries. Sepa¬ rate Dubowitz assessments on a single infant were completed within 2 hours of delivery, repeated again when the infant was 12 hours old, and then again at 24 hours of age. Descriptive data was collected concern¬ ing the infant's weight, apgar scores, and gestational age. A one-way factor ANOVA with repeated measures were performed on the Dubowitz scores obtained at the predetermined time intervals. Significant dif¬ ferences were found between the scores at 2 and 12 hours, 2 and 24 hours, and 12 and 24 hours at the £ = .05, .01, and .01, respectively. The findings of this study do not support the findings of time stabil¬ ity of Dubowitz (1977). The implications drawn from this study are that a need exists for assessing Dubowitz scores at specific times after delivery. 'These results indicate that policies should be specific regarding timing of the Dubowitz assessment. PERCEIVED IMMEDIATE NEEDS OF PARENTS WITH YOUNG CHILDREN IN AN INTENSIVE CARE UNIT. Carol L. Holcombe, R.N. , M.S.N., Cardiac Referral Coordinator, Baptist Medical Center - Montclair, Birmingham, Alabama, 35213. Jan E. Christopher, R.N., M.S.N., Instructor, University of Alabama School of Nursing, UAB, Birmingham, Alabama. The purpose of the study was to identify perceived immediate needs of parents with young children in an intensive care unit. The tool utilized for data collection was a questionnaire consisting of 45 need statements. Each statement was scored by the parents on a scale of 1-4, with 1 being least important and 4 most important. The sample consisted of 30 parents with a child between the ages of 1 and 4 in a pediatric intensive care unit. An item mean was calculated for each statement and ranked according to their mean scores. Based on the findings it was concluded that the need for explanations, information, and having questions answered honestly were perceived as most important by the majority of the subjects. 184 Abstracts SELF-ESTEEM IN THE KINDERGARTEN CHILD. Martha G. Lavender. University of Alabama School of Nursing, University of Alabama at Birmingham, Birmingham, AL 35294. The purpose of this study was to determine the relationship between maternal self-esteem, work status, and sociodemographic characteristics, i.e., age, sex, race, birth order, socioeconomic status, family structure, and child care arrangements, and self-esteem of the kindergarten child. The conceptual framework was derived from the Roy Adaptation Model of Nursing and self-esteem theory. The convenience sample of this study was comprised of 130 mother- child dyads. A stepwise multiple regression procedure was employed on the data. For the total sample, child care arrangements, family structure, age and sex were significantly related to the child's self-esteem (£ < .05). A significant relationship existed between child care arrangements and the self-esteem of kindergarten children of working mothers <£ < .05). The self-esteem of kindergarten children of non-working mothers was significantly related to age, sex, race, birth order, and maternal self-esteem (£ < .05). Based on the findings, a lower self-esteem in these children was related to child care provided by parents as opposed to relative or non-relative care. Two parent families, being male, and younger had a positive influence on the children's self-esteem. Among the children of non-working mothers, a high maternal self-esteem, being firstborn, and being black negatively influenced the children's self-esteem. Socioeconomic status was not related to the children's self-esteem. MYELOGRAM: RELATIONSHIP BETWEEN ROUTE OF FLUID ADMINISTRATION AND SEVERITY OF SIDE EFFECTS IN POST- I OPAM IDOL MYELOGRAM PATIENTS. Kathy H. Nelson, School of Nursing in the Graduate School, University of Alabama at Birmingham, Birmingham, AL. The purpose of the study was to determine the relationship between route of administration of fluids and severity of side effects in post-iopamidol myelogram patients. If the patient could be adequately hydrated with fluids by mouth, pre- and post¬ myelogram, the unnecessary risks, pain, and cost of the intravenous procedure could perhaps be eliminated. Orem's self-care deficit theory of nursing served as the nursing framework for the study. Subjects hydrated only by mouth or combined intravenously and orally were analyzed for severity of side effects following lumbar myelography. No statistically significant relationship between route of fluid administration and severity of side effects was found. From these results recommendations were made for nursing educators, future nursing research, and for nursing practice. 185 Abstracts SELENIUM BLOOD LEVELS IN RENAL DEFICIENT PATIENTS. A_;_ Mllly and L. C. Wit, Dept, of Zoology and Wildlife Sciences, Auburn, AL. 36849; C. J. Diskin, Opelika Nephrology Referral Center, Opelika, AL. 36801. Low blood selenium (se) levels have been proposed as a cause for the increased incidence of cancer and uremic cardiomyopthy in renal failure patients. The objective of this study was to determine if renal failure patients do, in fact, have low blood se levels and to correlate any changes in blood se with changes in the various se carriers such as RBCs, albumin and alpha-2 globulin. Blood se levels were determined in 3 groups (chronic renal failure, nephrotic syndrome, hemodialysis) of approximately 10 renal deficient patients, and from controls matched for sex and age. Se was determined in fractions of the blood (plasma and whole blood) by the method of wet digestion followed by flameless AAS with a graphite furnace. Additionally, se levels in the pre- and post-dialysate water of the hemodialysis patients were determined to detect losses across the dialysis membrane. Paired t-tests were used to determine differences in blood se, se carriers and pre- and post-dialysis water. The post-dialysis water of the hemodialysis patients had no more se than the pre-dialysis water. Neither whole blood nor plasma se levels differed between patients and controls within any group (p<.05). Within all groups, a positive correlation (r=*.3496; p*.01) existed between alpha-2 globulin and plasma se, while other se carriers showed no correlation. Alpha-2 globulin levels did not differ between patients and controls within any group. These data suggest normal levels of se and alpha-2 globulin in these patients and caution should be observed in prescribing se supplementation.

Ware, Department of Family Medicine, Univ. of Alabama, Tuscaloosa, AL 35487. HIV infection is certainly a disease inflicting an individual. However, it is a disease which affects individuals. This author has cared for HIV positive individuals in a rural area. In each case the effects encountered by the physician who becomes associated with any infected individual are quite taxing. The range of these effects extends from the physician and the office staff, to those who have a close relationship with the patient, and to the community at large. The physician must repeatedly reassure the office staff of its safety, and provide the necessary known precautions. The physician is fre¬ quently required to answer questions and concerns by those who are close to the patient. The community's concerns must be addressed by the physician for many reasons (i.e., to keep from losing patients, or to prevent unnecessary fears leading to violent consequences). For the treating physician, HIV infection is truly a disease of individuals. 186 Abstracts SWITCHING OF HEMOGLOBIN PROPORTIONS TOWARD NEWBORN VALUES IN ADULT RATS BY HYDROXYUREA IS BLOCKED BY ASPIRIN. Harold J. Spears and Mukul C. Datta, Dept, of Chemistry and Carver Research Foundation, Tuskegee University, Tuskegee, AL 36088. This study was carried out firstly to determine whether hydroxy¬ urea (HU) that induces fetal hemoglobin (HbF) synthesis in humans and primates can also induce newborn like Hb proportions in ml Idly anemic adult rats. If so, then secondly, to explore the possible involvement of other factor(s) in the process of HU-mediated Hb switching. Mild anemia was developed in normal adult Sprague-Dawley rats by controlled bleeding. A fixed dose of HU (75 mg/500g) was administered each time intravenously in each of such anemic rats for altogether 25 times cove¬ ring a span of 35 days. Anemia of moderate degree was maintained du¬ ring the entire drug regimen. Blood samples at several points of the drug treatment were analysed by ion-exchange chromatography to separate and quantitate the Hb components . A significant increasing pattern was measured for Hb components I, II and IV in red cells of the HU— treated rats compared to the anemic control rats, a situation analogous to that observed between normal adult and newborn samples. However, aspirin intake at a dose level of 20 mg/day/500g along with HU administration totally blocked the changeover of Hb components toward newborn propor¬ tions. Since aspirin is known to inhibit pros tag] and in synthesis, the present results reveal the importance of concurrent prostaglandin syn¬ thesis for the expression of the HU-mediated changes in Hb proportions toward newborn values in adult rats. Delineation of the mechanism of regulation of fetal hemoglobin in adults might be of therapeutic bene¬ fit in patients with sickle cell anemia or severe variants of homozy¬ gous beta— thalassemia. AMBULATORY HEALTH CARE IN THE WESTERN DEMOCRACIES: POLICIES TO FOSTER ITS EXPANSION. C. George Tulli, Jr., Capstone Medical Center, University of Alabama, Tuscaloosa, AL 35401. During the last two decades all the western democracies have had to face sharp increases in public spending for health service expenditures. In response, many governments have attempted to curb this unchecked growth by adopting various cost containment strate¬ gies. One such strategy embraces the expansion of ambulatory health services. The successful expansion of health services has apparent¬ ly occurred, however, when primarily coupled with government poli¬ cies that either restrict the availability of inpatient care or promote the expansion of primary health and medical care. From the data provided by the Organization for Economic Co-operation and Development, relationships were established between public spending on ambulatory health services and hospital occupancy rates (rs = 0.86} and between public spending on ambulatory health services and general practice physician population ratios (rs = 0.42) . 187 Abstracts PRELIMINARY STUDY OF GROUNDWATER MICROBIOTA ASSOCIATED WITH AQUIFER THERMAL ENERGY STORAGE (ATES). T. E. Thompson, C. E. Brett, F. S. Allison, J. A. Neville, C. Shea, and A. L. Winters, Dept, of Microbiology and the Natural Resources Center, Univ. of Ala., Tuscaloosa, AL 35487. R. J. Hicks, Pacific Northwest Laboratory, Richland, WA 99352. The Aquifer Thermal Energy Storage (ATES) system used at the Univerisity of Alabama is an engineering technology that uses thermal transfer from chilled groundwater to cool a recreation center. This technology has the potential for reducing the national demand for fossil fuels with a corresponding reduction in pollution. The objective of this project is to examine ATES-associated groundwater for possible changes in the indigenous microbial populations and for the presence of pathogenic microorganisms. Water samples are being collected from six sites within the ATES system over four seasons to develop a microbial profile of the associated aquifer water. Bacterial populations under investigation include heterotrophs , coliforms, and pathogens. Pathogens from the genera Legionella, Salmonella, Shigella, Campylobacter, Vibrio, Yersinia, and Mycobacteria are targeted for detection by selective cultivation methods. Data from one season of sampling indicate a stable heterotrophic population that contains low numbers of Pseudomonas and non-fecal coliform species. No human pathogens were detected, indicating that the ATES system does not contribute to pathogen levels in the aquifer during the winter cycle. Supported by Battelle Subcontract B-H5383-A-0. AN ASSESSMENT OF AGGRESSIVE BEHAVIOR IN FENFLURAMINE-TREATED RATS. Ronald N. Hunsinger , Jennifer Dole, and Joni Justice. Department of Biological Sciences, Samford University, Birmingham, AL 35229. Fenfluramine ( FN ) is a drug which causes a rapid release of brain serotonin. Thus, a single dose of the drug often elicits various ser¬ otonergic-dependent behaviors. Since FN also blocks the reuptake of serotonin into the nerve terminal, it is possible that repeated admin¬ istration of the drug might attenuate such functions, as a result of neurotransmitter depletion. In this study, we observed that a single dose of FN ( 10 mg/kg, i.p, ) significantly depressed attack behavior, a spontaneous form of aggression, in rats 24 h following drug injec¬ tion. Parallel locomotor tests conducted on these animals suggest that some sedation may have existed at the time of testing. In other trials, no significant differences in either spontaneous aggression or locomotor activity were observed in rats receiving FN ( 10 mg/kg, i.p.) for 14 days, as compared to saline controls. Additionally, predatory aggressive behavior, as assessed by the muricide test, in rats re¬ ceiving the 14-day FN regimen was no different from that of saline controls . 188 Abstracts COMMUNICATION SKILLS: EFFECTS OF TEACHING UNSKILLED HEALTH CARE WORKERS CONFIRMATION/DI S CONFIRMATION COMMUNICATION PATTERNS WHEN INTERACTING WITH ELDERLY CLIENTS. GLENDA AVERY, Marlys Bates, Ben Fones, & Donna Roper; Gay Reeves, Advisor, B.S.N., Miss. Univ. for Women, Columbus, MS 39701. The purpose of this study was to decide if unskilled health care workers' communication skills with elderly clients were significantly affected by a 45-minute teaching session on therapeutic communications. A quasi-experimental research design was implemented using a convenient sampling of 16 unskilled health care workers in a 142-bed rural nursing home. The experimental group consisted of eight unskilled health care workers who attended the teaching session. The control group consisted of eight unskilled health care workers who did not attend a teaching session. Three weeks after the teaching session, researchers made on¬ site observations of 173 interactions between unskilled health care workers and elderly clients. The observations occurred at two differ¬ ent time intervals. A checklist based on Heineken's modified version of the Sieburg tool on conf irmation/disconf irmation interactions and a master list identifying members of the experimental and control group was used to compile statistical data. Data analysis was obtained by using the Chi-Square goodness of fit one tailed-t^ test using p=.05, d . f . =7 ,X2 = 14 . 07 . The calculated t value was 1.79. Therefore, the re¬ searchers failed to reject the null hypothesis. The conclusion of the study was that the teaching session did not significantly improve un¬ skilled health care workers' therapeutic communication skills with the elderly clients. However, analysis of the data revealed the experimen¬ tal group demonstrated a 4% increase of confirmation patterns. This finding indicates that additional research may reveal significant statistical data to support the hypothesis of this study. COMPARISON OF JOB SATISFACTION IN STAFF REGISTERED NURSES. Gretchen A. Kennemer, University of Alabama Hospital, Birmingham, AL 35294. The purpose of this descriptive study was to ascertain if there is a difference in job satisfaction between staff registered nurses employed in the same institution for five or more years and new graduate nurses employed less than one year. The convenience sample consisted of 40 subjects, 20 of whom were staff registered nurses employed in the same institution for five or more years and 20 of whom were new graduate nurses employed less than one year. The Minnesota Satisfaction Questionnaire was used for data collection. Multivariant analysis of variance was used to test the null hypothesis. The Neuman Systems Model was found to be adequate and appropriate for the purpose of the study. There was a statistically significant difference on extrinsic satisfaction but not intrinsic satisfaction. New graduate nurses employed less than one year were more satisfied than the staff registered nurses employed in the same institution for five or more years. Implications for nursing practice and education are presented. Recommendations, including a larger and more representative sample as well as an investigation of the recognition and advancement variables of job satisfaction, are suggested for future research. 189 Abstracts ROLE STRAIN FOR THE MALE NURSING STUDENT IN THE OBSTETRICAL AREA. Roy Ann Sherrod, Capstone College of Nursing, Univ. of Ala. , Tuscaloosa, AL 35487-0358. The purpose of this study was to determine if there was a difference in the reported existence of role strain for male and female nursing students in the obstetrical area. Goode's (1960) theory of role strain and role theory were used as the conceptual framework. The null hypothesis was there would be no statistically significant difference in reported role strain as described by the Sherrod Role Strain Scale (SRSS) experienced by male and female baccalaureate nursing students in the obstetrical area. The SRSS was completed by 18 male and 18 female nursing students after their obstetrical nursing experience. Independent t-test comparisons of male and female nursing students on the overall scale and the four subscales of role strain overload, conflict, incongruity, and ambiguity at the 0.5 level of significance resulted in the rejection of the null hypothesis by the researcher. Implications for nurse educators and nursing were delineated with specific methods to facilitate a more rewarding educational experience for the male nursing student such as avoiding stereotyping, using anticipatory guidance, and presenting an equitable perspective. Recommendations for further research included replication of the study with exploration of relationships among selected demographic variables, refinement of the Sherrod Role Strain Scale (SRSS), and investigation of methods to reduce role strain. Other recommendations for nursing education and practice included the provision of an environment conducive to learning and reducing role strain for the male nursing student in the obstetrical setting. COMPARISON OF SELF CONCEPT OF SCHOOL AGE SURVIVORS OF ACUTE LEUKEMIA AND SELF CONCEPT OF HEALTHY SCHOOL AGE CHILDREN. Lisa D. South, University of Alabama School of Nursing, University of Alabama at Birmingham, Birmingham, AL 35294. This descriptive study was designed to ascertain if there was a difference in self-concept of school age survivors of acute leukemia and self-concept of healthy school age children. The sample consisted of 11 survivors of acute leukemia and 11 healthy children, aged 8 to 12 years, and matched for age, race, and sex. Instruments utilized were an investigator constructed demographic tool and the Piers-Harris Children's Self-Concept Scale. One way analysis of variance revealed a significant difference in self-concept between the two groups. Significant differences were also found between the two groups on the Physical Appearance and Attributes subfactor and the Intellectual and School Status subfactor of the self-concept tool. Recommendations for future research include: (a) longitudinal studies to assess developmental, environmental, and family influences on the self- concept, (b) comparison of children at different stages of cancer therapy, and (c) comparison of various treatment regimes in regards to self-concept. 190 Abstracts THE ECONOMIC IMPACT OF SPINAL CORD INJURY. Michael J. DeVivo, Dept, of Rehab. Medicine, Univ. of Alabama at Binn., Birmingham, AL 35294. This study examined the direct and indirect costs incurred by spinal cord injury patients, the aggregate costs to society and ways to reduce these costs using a combination of previously published information and new data from the National Spinal Cord Injury Statis¬ tical Center. Costs for patients treated at the University of Alabama Hospital were considered separately and compared with national cost estimates. Nationally, in 1987 dollars, average first year costs, which include initial acute care, rehabilitation and all post-dis¬ charge expenses up to the first anniversary of injury, ranged from $64,674 per person for neurologically incomplete paraplegics to $153,682 for neurological ly complete quadriplegics. Average annual costs thereafter ranged from $7,997 to $38,758, respectively. Over¬ all, the comparable range for the average present value for all direct costs following injury was from $186,744 to $507,611. Based on the likelihood of returning to gainful employment following injury, the average present value of forgone earnings was conservatively estimated to range from $139,625 for incomplete paraplegics to $284,371 for complete quadriplegics. Using current estimates of the incidence of spinal cord injury, conservative estimates of national aggregate annual direct costs were $2.24 billion while indirect costs were an additional $3.39 billion. Since life expectancies have been increasing for these patients, direct costs are expected to increase in the future while indirect costs may decline slightly. To reduce these enormous costs, increased efforts aimed at primary, secondary and tertiary prevention, as well as increasing the reemployment rate and utilizing more cost-effective treatment modalities will be needed. PILOT STUDY: EVALUATION OF DIETARY TREATMENT OF OBESITY IN A GROUP PRACTICE SETTING. Carol B . Murphree , Robert E. Pieroni, C. George Tulli, Jr. and Margaret P. Garner, University of Alabama, Tuscaloosa, Alabama 35401. How effective is the dietary treatment of obesity in a group practice setting? To answer this question, a pilot study of sixty- seven patients was conducted. The patients were divided into several categories, including demographic information, socio¬ economic status and weight reduction. For this limited sample, the results indicated that age, sex, education, and distance apparently had little bearing on potential weight loss. While equal percentages of men and women lost weight, women did have a higher percentage of weight gain. The documented cases of low motivation and negative family support were observed among the patients who gained weight. Another interesting result was that fifty percent of the patients lost weight between the physician referral date and the initial visit with the consulting dietitian. Regardless of whether or not the patients gained or lost weight after nutrition visits, thirty-four of the sixty-seven patients lost weight when the physician referred them to the dietitian. 191 Abstracts NURSING DOCUMENTATION . Darlene H. Renfroe, School of Nursing, Samford University, B'ham, AL 35229. The purpose of this study was to assess the relationship of nurses' attitude, subjective norm, and behavioral intention to their documentation behavior using Ajzen and Fishbein's theory of reasoned action. A total of 108 questionnaires with accompanying documentation data were obtained frcm staff nurses in three hospitals in the southeast. The nurses' attitudes, subjective norms, and behavioral intentions toward documentation were elicited using standard A j zen-Fishbein format. Documentation behavior was based on what should be documented in any hospitalized patient's chart in an eight-hour shift. The model was analyzed with LISREL VI. The overall fit of the final model bo the data was good, as judged by a chi-square of 3.41 (df=7, p=.845). The total coefficient of determination for the structural equation was .461. Results indicated that nurses' attitude toward documentation did not relate significantly to their intention to document optimally. Subjective norm did have a significant effect on behavioral intent. There was a significant positive relationship between subjective norm and attitude. Behavioral intent had a significant effect on documentation behavior, accounting for 15.2% of the variance. It appears that subjective norm, which is the influence of others, is what directs the intention to document and thus relates to the subsequent documentation. Reccrrmendations for practice include the camtunication of high ideals and expectations of important others to the staff nurse in order to improve the quality of documentation . AIDS SEROPOSITIVITY RATES IN SOUTHERN STATES: A DISTRIBUTION ANALYSIS. Robert E. Pieroni, College of Community Health Sciences, Univ. of Ala., Tuscaloosa, AL 35487-0326. Walter J. Jones, Health Services Administration, Memphis State University, Memphis, TN 38152. James A. Johnson, Dept, of Health Services Administration, Medical University of South Carolina, Charleston, SC 29425. In analyzing the development and spread of AIDS in Southern states, it is clear that the states of Florida, Georgia and Louisiana have been most severely afflicted to date. These three states have the highest cumulative totals of AIDS cases, as well as the largest number of cases reported in 1988. However, the rate of increase in reported AIDS cases is actually higher in other Southern states (such as Mississippi and alabama) which have not been as affected by the AIDS epidemic until recently. Southern metropolitan areas most affected by AIDS include Miami, Fort Lauderdale and Tampa in Florida, and Atlanta, Georgia. As in other regions, the spread of AIDS in the South has disproportionately affected black and latino minority groups, and has recently involved a decline in the proportion of cases involving homosexual and bisexual males, and a corresponding increase in reported AIDS among IV-drug-using males and females. 192 Abstracts MJNCHMJSEN'S SYNDROME: A CASE REPORT AND LITERATURE REVIEW. Richard Gist and Robert Pieroni, College of Caimmity Health Sciences, Univ. of Ala., Tuscaloosa , AL 35487. Munchausen's syndrome encompasses three clinical entities, each of which has sore similar features. These have been classified as A) a factitious disorder with physical symptoms, B) a factitious disorder with psychiatric symptoms, and C) a factitious disorder with atypical symptoms. The most cannon presentation is type A. Patients with this disorder usually fabricate elaborate and often convincing symptans in order to gain admission to medical facilities. These patients may undergo painful and frequently dangerous diagnostic and therapeutic procedures in order to remain in the health care facility. They often display extensive medical knowledge and, occasionally, are narcotic abusers. It is postulate! that the primary gain for these patients is attention by the medical and nursing staff - attention that had been denied them as a result of parental neglect, abandonment, or abuse. This is in contrast to malingering, in which there is usually a primary gain, e.g. narcotics for support of an addiction, food and shelter, or escape fron legal authorities. Munchausen's syndrome may also present with psychiatric symptoms or atypically, such as by proxy. We will describe the case of a thirty-eight year old white male who presented to the Capstone Internal Medicine Service at DCH Regional Medical Center with very convincing cardiac symptomatology . On further evaluation he was found to fulfill criteria of Munchausen's svndrare, type A. His hospital course and a review of germane litera¬ ture will be presented, as will methods to help medical personnel identify this intriguing syndrore. DETERMINATION OF INITIAL LIFT RESISTANCE IN A STRENGTH TRAINING PROGRAM Terry Hoobler and Kennon Francis, Division of Physical Therapy, Univ. of Ala. at Birmingham, Birmingham, AL 35294. Determination of baseline strength measurements using cable tensi¬ ometer, weight prediction tables and one/five/ten repition maximum (RM) lifts were compared with isometric and concentric strength measures from the Lido 2.0 Active Isokinetic Dynamometer in the same population. . 30 healthy males, ages 18 to 43, with no prohibiting medical conditions were tested. All subjects were randomly tested for baseline maximal strength using each of the assessments listed above. All methods incl¬ uded calibration with standardized weights. A Pearson Product Moment Correlation was used to examine the relationship between variables. Results of the study indicated high correlations and statistical sign¬ ificance (p 0.01) between the data from the Lido 2.0Act and: one/five/ ten RM free weight lifts, cable tensiometer values at 90 and 120 degrees of motion. Cable tensiometer values at 45 degrees of motion and prediction of initial lift with weight based tables were not statistic¬ ally significant. This study supports the use of one/five/ten RM tests or isokinetic dynamometer measurement for determining intial lift resistance in setting up an exercise program. 193 Abstracts AMP DEAMINASE ISOZYMAL CHANGES IN THE HEART OF STREPTOZOTOCIN DIABETIC RATS. Ronald L. Jenkins Dept. Biology Sam ford Univ. Birmingham"^ AL 35229, Linda Atkins and Huey G. McDaniel, Veterans Administration Medical Center, Birmingham, AL 35233. Five adult male Long-Evans rats were made diabetic with 40 mg/kg, ip. injection of streptozotocin. Five male litter mates served as control. The diabetes was pronounced (>400 mg% blood glucose) from the 3rd until the 28th day. Isozymes of AMP deaminase from mitochondrial and from cytosolic fractions were separated on cellulose phosphate with a linear gradient of KC1 (50 mM to 1000 mM) . AMP deaminase activity from column eluants was determined by the rate of conversion of AMP to IMP which was quantited by ion-pair HPLC (J. Chromoatograhy 1988, 426:249). The three isozymes of AMP deaminase, according to the KC1 elution and their % of total activity were: 0.17 M (85%), 0.25 M (8%) and 0.33 M (7%) KC1. The 0.17 M KCl isozyme was the sole component of mitochondria. After four weeks of diabetes the heart isozymal profile dramatically changed to: 0.17 M (10%), 0.25 M (75%), and 0.33 M (15%). The isolated isozymes were pooled and fractionated in (20— 40%) ammonium sulfate with a 900 fold purification. The kinetics of the three isozymes proved to be distinctive: 0.17 M KCL: AMP Km = 17.9, stimulated by ATP, ADP, and NAD 0.25 M KCL: AMP Km = .97, inhibited by ATP and NAD 0.33M KCl: AMP Km = .66, stimulated only by ADP. IDENTIFICATION OF 'THE INFORMATION NEW MOTHERS PERCEIVE AS HELPFUL DURING EARLY BREASTFEEDING. Lee Ann Street, 3334-A Avery Drive, Fort McClellan, AL 36205. A qualitative descriptive study of 23 primiparous mothers was done to identify the information perceived as helpful during early breastfeeding and its sources. A telephone interview was conducted three weeks after delivery. The 15 mothers who were successfully breastfeeding at three weeks most frequently cited information concerning nipple/breast care and the supply and demand process of lactation as most helpful. The eight mothers who had stopped breastfeeding by the three week date reported problems in these areas critical enough to end their breastfeeding attempts. Health professionals were the least reported sources of helpful breastfeeding information.. Subjects cited books or pamphlets and family or friends most frequently. Incorporation of nipple and breast care specifics, as well as the supply and demand process of lactation into breastfeeding education is indicated. Health professionals need to reestablish their significant role in providing information to those mothers desiring to breastfeed their infants. 194 Abstracts PROTEIN SUPPLEMENTATION OF IVF MEDIA AFFECTS PREIMPLANTATION MOUSE EMBRYO DEVELOPMENT. joe R. Warren and Wayne H. Finley, Department of Medical Genetics, Charles P. Dagg, Department of Biology, and Michael P. Steinkampf, Department of Obstetrics and Gynecology, University of Alabama at Birmingham, Birmingham, AL 35294. Mouse embryo development has been used as a quality control assay in many in vitro fertilization (IVF) programs. Many factors, including media and sera quality, toxicity of certain IVF products or reagents, and pH or other environmental changes have been previously reported to have an effect on this development. In this 2-year study, the effects of supplementing Ham's F10 medium with human serum were examined. Embryo development in BWW-BSA medium (Biggers, Whitten, and Whittingham medium supplemented with bovine serum albumin) was used as the control. In addition, the effects of supplementing Ham's F10 with BSA. instead of human serum were also examined. It was determined that different lots of serum could have varying effects on embryo survival, supporting normal cleavage to the blastocyst stage from 0% up to 100% of the time. In contrast, BWW-BSA and Ham's F10 supplemented with BSA generally supported increased and more consistent embryo survival rates, and Ham's F10 without protein supplementation was capable of supporting embryo development up to hatching. However, hatching rates increased significantly in the presence of a protein supplement and attachment to the culture dish followed by trophoblastic outgrowth occurred only in the presence of human serum. ATTITUDES TOWARD ELDERLY AND INFANT: IS THERE A DIFFERENCE? Barbara B. Pickens, School of Nursing, University of Alabama at Birmingham, University Station, Birmingham, Alabama 35294. Research supported that attitudes toward the elderly among society as a whole were negative, the needs of the elderly came second to those of smaller but younger population groups, almost all health profes¬ sionals prefer to work with children or younger adults, and that few choose to specialize in geriatrics. The purpose of this study was to describe baccalaureate degree students' (BSN) attitudes toward the elderly and infant patient. The hypothesis for the study was "there will be no significant difference in BSN students' attitudes toward the elderly and infant patient." The subjects were 150 junior BSN students enrolled at a large university in the Southeastern U.S. Half of the subjects were given a case presentation (CP) identified as an elderly patient and the other half were given a CP identified as an infant patient. The content of both CPs was identical. After reading the CP the subjects completed the evaluative dimension of a semantic differen¬ tial. Using ANOVA, the hypothesis was rejected at the .05 level of significance (p<.001). There was a statistically significant difference in the BSN students' attitudes toward the elderly and infant patient . 195 Abstracts CALCULATION OF INTRACELLULAR TRANSPORT OF OXYGEN IN HEART MUSCLE BY MYOGLOBIN K. S. Yackzan, Diabetes Research & Training Center W. J. Wingo,* Emeritus, Department of Biochemistry University of Alabama at Birmingham Birmingham, Alabama 35294 Myoglobin (Mb) is of interest from a number of viewpoints. An example of its ability to bind fatty acids is shown by experimental and model studies. The intracellular oxygen (0^) transport function of Mb has been postulated, but to our knowledge has not been theoretically calculated using our assumptions. We calculated the percentage of transported by Mb in heart muscle based on literature data and certain assumptions: (1) 0.25% Mb in heart muscle; (2) Partial 0~ pressure (PO^) of 25 mm Hg at the sarcolemma and 1 mm PO2 at the mitochondrial membrane (MCM) ; both PC^ values being conducive to the diffusion of 0^ to the interior of the mitochondrion; (3) Sarcolemma-mitochondrial membrane distance = 7.75 x 10-7 cm; (4) We used the values of diffusion constants for Mb and 0^ and the Keq for the O^-Mb system to calculate the relative amounts of 0^ carried by a simple diffusion and by Mb. Mb transports a significant fraction (=90%) of the intracellularly diffusing oxygen as MbO^. Supported by grants from Diabetes Trust Fund. FIELD STUDIES OF POTENTIAL TICK VECTORS OF LYME DISEASE IN ALABAMA. Shirley Luckhart and Gary R. Mullen, Dept, of Entomology, Auburn Univ., Alabama, 36849-5413. In March 1986, the first serologically substantiated case of Lyme borreliosis was reported in Alabama. Since that time, 5 additional confirmed cases have been reported in Lee county, AL. The clustering of these cases and lack of travel in the case histories suggest autochthonous transmission of the agent, Borrelia burgdorferi. In an attempt to characterize the transmission cycle of this agent in Ala¬ bama, 1 ive-captured rodents and hunter-killed deer in areas immediate¬ ly adjacent to confirmed cases were examined for ticks. Attached ticks were either removed in the field or allowed to complete engorgement and drop off in the laboratory. Adult, nymphal , and larval Ixodes scapularis, Dermacentor variabil is, D . nigrol ineatus, D_. albipictus, and Amblyomma americanum collected from cotton mice (Peromyscus gossypinus), golden mice (Ochrotomys nuttalli), cotton rats (Sigmodon hispidus) , short-tailed shrews (Blarina brevicauda), house mice (Mus~ muscul us ) , and hunter-killed deer were dissected and examined for the spirochete with fluorescently-labelled polyvalent anti-B. burgdorferi conjugate. Borrel ia-1 ike organisms were detected in ticks recovered from P_. gossypi nus and deer in areas where transmission is likely to have occurred. 196 Abstracts PILOT STUDY IN PROGRESS-SELECTED DEMOGRAPHIC AND ACADEMIC PREDICTORS OF SUCCESS OF BACCALAUREATE DEGREE NURSING STUDENTS AT THE UNIVERSITY OF ALABAMA SCHOOL OF NURSING AT BIRMINGHAM. Gayle Becker, Pat Cleveland, Mary K. Peacock, Linda Reed, Catherine Shields, Mvra Smith, Judy Taylor, Janice Vincent, Joan Yeager, and Joan Burttram. A descriptive pilot study is being conducted to determine if it is possible to predict student success in a baccalaureate nursing program by examining the relationship between selected demographic and academic variables. The data collected to date was obtained by surveying student records for the following: race, age, sex, marital status, number of children, previous education and work experience, grade point average end of freshman year (GPA-1), Watson-Glaser (WG) and Nelson Denny (ND) test scores, and Adult Health course grade. In addition, the faculty of the first clinical nursing course were asked to predict student success in the program. For the purpose of the pilot study, success in the program was defined as successful completion of Adult Health Nursing. A moderate positive correlation was found to exist between GPA-1 and the Adult Health grade. A weak positive relationship also existed between the WG and ND percentile scores and the Adult Health grade. The two variables which helped to explain the variance of scores in Adult Health were GPA-1 and educational background. GPA-1 accounted for 28% of the variance in grade and an additional 10% of the variance could be explained when educational background was included. Race made a difference in student program success; approximately one third of the black subjects were unsuccessful. The other variables did not have significance in our study. PERCEPTIONS OF NURSING SERVICE ADMINISTRATION GRADUATE STUDENTS REGARDING THE UTILIZATION OF THE CLINICAL NURSING SPECIALIST IN THE HOSPITAL SETTING. Patricia A. White, Clinical Nursing Specialist, Baptist Medical Center-Princeton, Birmingham, A1 35211 The sample in this study consisted of graduate students in one of the last two quarters prior to graduation. Data were obtained by use of a questionnaire previously used with nursing service administrators (NSAs). The data indicated that of the five roles of the clinical nursing specialist (CNS) -consultant , teacher, researcher, clinician, manager-the first three roles were perceived by these future NSAs as being the most important. Interpersonal skills, such as verbal and non verbal communication patterns and the ability to listen, were viewed as being of great importance for optimum utilization of the position of CNS. Results of this study have implications for both prospective NSAs and CNSs. Future NSAs and CNSs should seek to improve their knowledge of the functions and roles of the CNS. It is recommended that another research study be conducted by using a larger sample size from a cross-section of graduate schools with nursing service administration programs. It should be noted that this is the first of a two part study to determine also if the perception of these nursing service administration graduate students change once these students are in practice for two years. 197 Abstracts MORAL DILEMMA DISCUSSIONS AND MORAL REASONING. Beth S_l Hembree. College o-f Nursing, Jacksonville State University, Jacksonville, AL 36265 . The purpose o-f this study was to determine the e-f-fect o-f moral dilemma discussions utilized in an ethical decision-making course on moral reasoning levels o-f senior generic baccalaureate nursing students and registered nurses who were completing the baccalaureate degree. Sixty-seven senior baccalaureate nursing students were non-randoml y assigned to treatment and control groups. Each o-f the two treatment groups, generic and registered nurse, were enrolled in a 5-week ethical decision-making course which emphasized moral dilemma discussions. Moral reasoning was assessed by administering the Defining Issues Test (Rest, 1986) as a pretest and posttest. Statistical analysis with an independent t-test on pretest data revealed no significant difference in moral reasoning levels between generic and registered nurse students. Dependent t-tests indicated a significant increase in principled level moral reasoning 70 % of county) of commercial forests that were being clearcut (Alabama Forestry Association 1985), and had the potential to provide favorable ground dove habitat (Landers and Buckner 1979). Changes in forestry practices in Alabama also could have adversely affected ground-dove populations. Suppression of wild fires was common before fire was recognized as a valuable tool of foresters. Fire sup¬ pression allowed succession to proceed to the detriment of most wildlife species associated with the longleaf pine forest type. Fire suppression probably also altered the mosaic patterns that occurred naturally by reducing the amount of land in early serai stages. Additionally, vast areas were converted to even- aged pine plantations for lumber and/or pulpwood production. These plantations were suitable, and even desirable, for many species during early serai stages (Johnson 1987) , but proved to be poor wildlife habitat after canopy closure. Large areas of open land were converted, or allowed to succeed, to forests. The ultimate result has been a decrease in the amount of available ground-dove habitat. Land use patterns and ground-dove densities In the counties surveyed are consistent with the contention that ground-doves may require minimal amounts of land In early serai stages to sustain viable populations. Data on the effects of habitat fragmentation on animal populations are numer¬ ous. However, most of the work on fragmentation has dealt with forests (Harris 1984, Yahner 1985, Haila et al. 1987) and not relatively open ecosystems. Fragmentation of early serai stages by the interspersion of large tracts of wooded areas could impede dispersal of ground-doves since 230 Jones and Mirarchi they are not exceptionally strong fliers. This would lead to a contrac¬ tion of their range into areas where a large proportion of the land is still in early serai stages. Rights-of-way or other corridors that are maintained in early serai stages might offer opportunities for ground- doves to disperse across otherwise unsuitable habitat, but there has been no documentation of such utilization. Other factors also may be limiting ground-dove populations. Mount (1981) postulated that the imported red fire ant (Solenopsis LnvicCa ) has been a factor in the decline of ground-doves in Alabama. Although no direct evidence of fire ant predation on ground-dove nests exists, there is growing evidence that fire ants can be a serious threat to other altricial species such as northern cardinals (Cardinalis cardinalis ) (Conner et al. 1986), and cliff swallows (Hlrundo pyrrhonota ) (Sikes and Arnold 1986) . Professional and lay conservationists across Alabama also report that ground-doves are regularly shot by mistake during mourning dove hunts. These mistakes occur because many hunters are unaware that more than one species of dove exists in the state, and others have difficulty distin¬ guishing between the species. Additionally, Alabama hunting regulations specify that "doves" are legal to hunt in season and make no distinction between state and federally protected species such as the common ground- dove and game species such as mourning or white -winged doves (Zenaida asiaClca ) (Ala. Dept. Conser. and Nat. Res. 1988). Pesticides associated with agricultural and forestry practices also could be contributing to the ground-dove's decline. Ground-doves frequent agricultural areas and young pine plantations and could come in contact with a variety of pesticides in use there. Although no intensive studies of ground-dove - pesticide interactions have been conducted, carcasses of ground-doves have been recovered after pesticide applications to agricul¬ tural fields in Alabama (M. Wallace, pers. comm.). SUMMARY AND RECOMMENDATIONS The common ground-dove should remain a Species of Special Concern in Alabama and their populations should be closely monitored because of reduced distribution in the state, low densities, instability of the populations as a result of land use changes, incidental hunting kills, and possibly other undetermined factors. This status should be retained until future research indicates a stabilization or increase in population numbers . Additionally, a public relations program should be initiated in Ala¬ bama to inform dove hunters of the existence of ground-doves, that they are declining, and that they are protected by state and federal law. Posters showing the differences between common ground- doves and mourning doves (i.e., size, color, wing shape, and tail length) should be dis¬ tributed statewide to lessen the Impact of incidental hunting pressure on the species. Law enforcement personnel then should be instructed to strictly enforce protective statutes and regulations. 231 Common ground-doves in Alabama Although major changes in land use and habitat composition for the entire state cannot be predicated on one species of wildlife, certain practices will ensure the continued survival and increase of the common ground-dove in Alabama. Where feasible, early serai stage habitats should be protected and maintained. Along the coast, dune communities should be protected to benefit ground-doves and other threatened species. In the Coastal Plain, longleaf pine-wiregrass communities should be protected and maintained with more natural fire regimes. In agricultural areas, ground-dove habitat should be created by using fire, or selective mowing on 1-3 year rotations to ensure a mosaic of suitable areas. The nationwide trend toward integrated pest management in agriculture should be encouraged in Alabama so heavy pesticide use can be curtailed. Foresters should retain mechanical site preparation until the effects of chemical site preparation are determined. Additionally, regeneration areas should be kept small and in close proximity to each other. Other studies should be conducted in Alabama and other states within the range of the common ground-dove to determine what specific factors, if any, limit their populations. Such efforts should determine the effects of habitat fragmentation on ground dove populations; the effects of imported fire ants on ground-dove reproduction; the amount of inci¬ dental hunting pressure exerted on ground-doves; and the effect of pesticides on ground-dove survival and reproduction.

LACK OF EFFECT OF THE BETA-AGONIST CIMATEROL ON GROWTH AND COMPOSITION OF NEONATAL RATS' J. A. Chromiak Interdepartmental Physiology Program Auburn University , AL 36849 and D. R. Mulvaney and D. R. Strength Department of Animal and Dairy Sciences Alabama Agricultural Experiment Station Auburn University , AL 36849 ABSTRACT The purpose of this study was to determine the effect of cimaterol administration on body and muscle growth of neonatal rats, and the effect of cessation of cimaterol treatment on subsequent postnatal growth. Male rats were injected with 0, 0.5, 1.0, or 2.0 mg/kg BW cimaterol daily from 7 to 21 days of age. Six rats per treatment group were killed at 21 and 42 days of age. Various skeletal muscles and the heart were dissected and weighed, and carcass protein and fat content determined. Data at 21 or 42 days were analyzed with an ANOVA, with Duncan's multiple range test as the post-hoc test. Body weights were not different across cimaterol dosage groups at 21 or 42 days of age. There were no differences in net BW gain for the 7 to 21 day or 21 to 42 day periods. Compared to the 0 mg/kg group, percentage and total carcass fat and protein were not affected by cimaterol treatment. Weights of the heart and skeletal muscles were unaffected by cimaterol treatment, except at 42 days when gastrocnemius and soleus muscle weights were reduced in the 1 mg/kg group. It is concluded that cimaterol at 0 to 2.0 mg/kg BW does not affect the body and muscle growth of neonatal rats. INTROUDUCTION Administration of beta-adrenergic agonists to various species of animals has been shown to alter body composition by increasing muscle mass and reducing body fat (3,10,14). Beta-agonists, such as cimaterol and clenbuterol, are selective for the receptor (16), and cause nutrient repartitioning in livestock (3), and rats (10,13). Subcutaneous in¬ jection of clenbuterol twice daily at 1.0 mg/kg body weight (BW) increased weight gain in 150 g rats by 27% (10). This increased gain in clenbuterol treated rats was due to an elevated fat- free mass with no difference in total body fat content between control and clenbuterol treated groups. Administration of clenbuterol in the diet of rats (13) and by subcutaneous injection (2 mg/kg BW) to mice (15) increased both body and muscle weights, and decreased percent body fat. Beta-agonists reduce fat 'Manuscript received 1 February 1989; accepted 5 April 1989. 235 Cromiak, Mulvaney, and Strength accretion due to direct effects on lipid metabolism (5); however, the cellular mechanisms involved in the enhanced muscle hypertrophy have not been resolved. Neonates may not respond to beta- agonists in the same manner as older animals as recent data demonstrated that cimaterol can have a negative impact on growth of rats 7 to 21 days of age (6). Daily injection of 0, 2, 4, or 8 mg/kg cimaterol depressed body weight gain and muscle weights at higher doses in rats selected for large and small mature body size. However, cimaterol had a greater impact on the body and muscle growth of the large strain rats compared with the small strain rats. Following cessation of beta-agonist administration, body composition apparently returns rapidly to control values (2). In obese mice (ob/ob strain), dietary administration of the beta-agonist, BRL 26830, for 28 days resulted in a 17% reduction in body weight, and a 28% decrease in body fat content compared to a control group. However, 21 days after removal of BRL 26830 from the diet of the ob/ob strain of mice, body weight and composition had returned to values similar to the control group. Whether these kinds of responses for muscle weight would occur following withdrawal of cimaterol have not been reported. Due to an inhibition of growth at high doses of cimaterol in neonatal rats in an earlier study (6) , the present study was conducted to determine if administration of lower doses of cimaterol from 7 to 21 days of age would promote or Inhibit body and muscle growth. The effect of withdrawal of cimaterol on subsequent body and muscle growth was also examined in order to determine the impact of altering growth during the neonatal period on subsequent postnatal growth. Manipulation of growth, positive or negative, at this age may have a significant impact on ultimate body size and composition. MATERIAL AND METHODS Charles River CD strain male rat pups from litters representing a population that had been genetically selected for large size over 13 generations were used for this study. At 12 weeks of age, mean weight of male rats from the large strain was 470 g compared to 380 g for males from the unselected control strain (unpublished data) . To minimize litter effects, the number of rats per litter was normalized to 8 pups per lit¬ ter. At 7 days of age, forty-eight rats were randomly assigned to one of 4 treatment' groups consisting of rats that received subcutaneous injec¬ tions of 0, 0.5, 1.0, and 2.0 mg/kg body weight of cimaterol (American Cyanamid, Princeton, NJ) between 0800 and 1000 h daily. Six rats in each dosage group were also designated to be killed at 21 or 42 days of age. Cimaterol was dissolved in propylene glycol, and administered by injection of volumes standardized across treatment groups (50 or 100 ul) . Rats in the 0 mg/kg group received propylene glycol only. Nursing females and respective litters were provided free access to a complete rat chow diet (Purina Mills, St. Louis, MO) and water. At 21 days, rats were weaned and all injections terminated. 236 Effect of cimaterol on growth and composition of neonatal rats At slaughter, rats were euthanized with chloroform, decapitated, and the hide, tail, and paws removed. The heart and various skeletal muscles from the left forelimb or hindlimb were dissected, trimmed of connective tissue, blotted lightly with gauze, and weighed. The skeletal muscles excised were the triceps brachii, semitendinosus , soleus, gastrocnemius, plantaris, extensor digitorum longus (EDL) , and tibialis anterior. The remainder of the internal organs were removed, the carcass weighed and frozen in liquid nitrogen and stored at -20 C until further analysis. Carcasses were autoclaved for 4 h, mixed with an equal volume of distilled water, and homogenized with a Polytron homogenizer (Brinkman Instruments, Westbury, N.Y.). The homogenizer tip and beaker were rinsed with distilled water, which was added to the homogenate, and the total homogenate volume determined. Homogenates were divided into 2 aliquots for determination of protein using micro -Kjeldahl analysis (1) and lipid content using the procedure of Bligh and Dyer (4) . Data for body and tissue weights, BW gain, and body composition at 21 or 42 days were analyzed with an analysis of variance (ANOVA) . When ANOVA indicated statistical differences between cimaterol treatment groups, Duncan's multiple range test was used to test for differences between individual means with p values equal to or less than 0.05 accepted as significant (17). RESULTS There were no differences in body weights across the four cimaterol dosage groups at 21 days of age, or at 42 days of age after the rats had been removed from cimaterol treatment for 21 days (Table 1) . There were no differences in net body weight gain (Figure 1) for the 7 to 21 day and 21 to 42 day periods. Compared with the 0 mg/kg group, percentage and total carcass protein and fat content at 21 and 42 days of age were not affected by cimaterol administration (Table 1). At 42 days the percentage carcass protein of the 2.0 mg/kg group was lower than the 1.0 mg/kg. At 21 days, there were no differences in the weight of the heart and skeletal muscles across the four cimaterol dosage groups (Table 2). At 42 days, the weight of the soleus and gastrocnemius muscles in the 1.0 mg/kg group were 78.0 and 80.6% of the values of the 0 mg/kg group. There were no other differences for muscle weights at 42 days across the treatment groups. Liver and kidney weights at 21 and 42 days were unaffected by cimaterol treatment (data not shown) . DISCUSSION The present study was conducted to determine the effect of low doses of cimaterol on body and muscle growth of neonatal rats. In previous work, cimaterol administration to neonatal rats from 7 to 21 days of age inhibited growth at 4 and 8 mg/kg BW in large strain rats, but did not affect carcass composition (6). It was clear that neonatal rats do not respond to beta-agonist treatment in the same direction as older rats treated similarly (10, 13, 15). It was suggested that energy expenditure 237 Cromiak, Mulvaney, and Strength Table 1.

If high dosages of cimaterol elevated the metabolic rate of neonatal rats, less energy would be available for whole body and muscle growth. Therefore a narrower and lower dosage range was employed in the present study. However, injections of cimaterol at 0 to 2 mg/kg of body weight did not affect body and muscle growth. This is consistent with the recent study of Mersmann et al . (12) in which dietary cimaterol at 0 to 0.5 mg/kg for 10 wk had no effect on growth and carcass composition of young, rapidly growing pigs. Age or maturity of an animal may affect responsiveness to beta- agonists. Although administration of 0 to 2 mg/kg cimaterol did not affect the growth of neonatal rats in the present study, it has been demonstrated consistently that beta-agonists promote body weight gain, reduce percent fat, and increase muscle weight in older animals (3,10, 13,14). For example, subcutaneous Injection of epinephrine at 10 mg/d (approximately 0.15 mg/kg BW) for 10 to 30 days increased nitrogen retention 10.4 to 22.7% and body weight gain 11.0 to 18.7% in adult castrated male pigs (7). However, injection of epinephrine (0.0625 mg/kg to 0.2 mg/kg) to 3 to 4 week old female and castrated male pigs for 6 weeks resulted In decreased growth rates. Young pigs receiving epineph¬ rine had 2.8 to 6.5% more carcass protein and 0.5 to 23.4% less fat compared with a control group, but weighed 95 to 99% of controls. Epi¬ nephrine injections increased the growth rate of older pigs but restricted the growth rate of young pigs when administered at equivalent or lower doses. Epinephrine had little effect on fat deposition of older pigs but decreased fat storage in younger animals. In the present study, total carcass fat and percent fat were not different between cimaterol treated rats and 0 mg/kg controls. Dietary energy and tissue reserves available to the neonatal rats may have been inadequate to support any reparti¬ tioning effects due to cimaterol administration. Animal genotype may affect responsiveness to beta-agonists (6,9). In mice selected for rapid 3 to 6 week weight gain, dietary cimaterol at 50 ppm at 4 to 10 weeks of age had no affect on body weight gain, but 200 ppm depressed body weight gain (9). In a control strain, 50 ppm cimaterol resulted in increased body weight gain compared with the 0 ppm diet, but 200 ppm cimaterol did not affect body weight gain. In both strains, epi- didymal fat pad weight and subcutaneous fat weight expressed as a percent¬ age of empty body weight decreased consistently as the level of dietary cimaterol increased. The lack of effect of cimaterol on muscle weight in this study with neonatal rats is in contrast to increases of 10 to 35% in the weight of various skeletal muscles in older rats given clenbuterol compared to controls (10,11,13,18). In previous work (6), cimaterol at higher doses (2 to 8 mg/kg) inhibited the growth of the triceps brachii, gastrocnemius, brachialis, and peroneus muscles 10 to 40% in neonatal rats. It appears that the doses used in the present study were too low to inhibit muscle growth in neonatal rats . 240 Effect of cimaterol on growth and composition of neonatal rats In contrast with a reported increase in heart weight with beta- agonist administration (8), cimaterol had no effect on heart weight. The doses used in the present study were sufficient to induce cardiac hypertrophy, since daily administration of 0.1 mg/kg of isoproterenol induced significant cardiac hypertrophy within 3 days (8). After 21 days, weight of the heart was 40% greater in the rats given isoproterenol compared to controls. Discrepancies between studies may be due to differences in structure and beta-receptor selectivity of the beta- agonists. Cimaterol is f}2 selective, while isoproterenol is a non- selective beta-agonist. Growth of rats post-weaning after termination of cimaterol treatment was examined to determine the impact of withdrawal of the beta-agonist on subsequent growth. Cessation of cimaterol administration at 21 days of age had no effect on subsequent body and muscle growth to 42 days of age. Body weight and lipid content in ob/ob strain mice were decreased due to administration of a beta-agonist for 28 days, but had returned to control values within 21 days after removal of BRL 26830 from the diet (2) . In the present study, cimaterol administration did not affect growth from 7 to 21 days of age; therefore, it might be expected that cessation of treatment would have little effect on subsequent growth. It is concluded that cimaterol administration at 0 to 2 mg/kg daily does not affect body and muscle growth of rapidly growing neonatal rats bred for large mature body size. It is suggested that future studies are needed to determine the relationship of age and genotype to the effectiveness of beta- agonists in promoting growth. REFERENCES 1. A.O.A.C.

REGISTERED NURSES' RESPONSES TO REPORTING ABUSE: A SURVEY OF HOME HEALTH AND COMMUNITY HEALTH NURSES IN ALABAMA* Carolyn Lea Clark-Daniels Center for the Study of Aging College of Community Health Sciences University of Alabama Tuscaloosa, AL 35487 ABSTRACT Abuse of the elderly is a problem of some magnitude. A survey of nurses in the fields of home health and community health concerning the detection of abuse and the law on mandatory reporting of abuse, neglect, or exploitation was conducted in 1988. The nurses who were surveyed were confused about the mechanics and operation of the law and expressed some reluctance about reporting abuse or neglect to the authorities. Furthermore, nurses believed that there were not enough protective services provided for those who had been abused or neglected. The most disturbing aspect of the survey was the high level of dissatisfaction with the current law expressed by all categories of nurses. Review of the Literature Abuse of the elderly is difficult to detect because the problem is often obscure. The abuse remains hidden because the victim frequently fears public exposure with its accompanying shame, embarrassment, and guilt over what has happened; because the victim sometimes fears retali¬ ation or removal from the abode and placement in a nursing home; or because they are too passive or sick to remedy the situation. As a result, no accurate estimate of the extent of the problem has been developed. One author calculated that approximately one in every 25 (or 4%) of elderly Americans (>1.1 million) are probably victims of abuse (Clark, 1981). The House Select Committee on Aging reported that there were approximately 100,000 abuse victims annually (U.S. House of Repre¬ sentatives, 1985). Others conclude that elder abuse occurs with about the same frequency as child abuse (Crouse, Cobb, Harris, Kopecky, and Poertner, 1981; Kosberg, 1986; O'Brien, 1987). Unfortunately, all of these estimates were based on haphazard sampling techniques. Pillemer and Finkelhor (1988) extrapolated an abuse rate of 3.4 percent of the elderly population from a random sample taken in the Boston metropolitan area. However, the sample was limited geographically and by the reluc¬ tance of respondents to discuss abuse. Despite these differences in estimation, significant agreement exists that abuse of the elderly is a serious, ongoing problem. ^Manuscript received 14 March 1989; accepted 12 May 1989. 243 Clark-Daniels Most often, social policy response to abuse or neglect of the eld¬ erly has taken two forms, protective services legislation and mandatory reporting legislation (Kosberg, 1986). Currently, all 50 states use one or both of these two approaches. Protective services usually involve the provision of both voluntary and involuntary services to the physically or mentally infirm, older adult who has been abused, neglected, or exploited (Faulkner, 1982). While protective services historically have helped to protect vulnerable adults from "abuse, maltreatment, self- destructive behavior, and other forms of adversity," (Kosberg, 1986) they also exacerbate existing legal difficulties. Problems such as the absence of due process safeguards and interference with protections against the invasion of the rights to privacy and self-determination, often place the abuse victim at the mercy of institutions whose goals may not match their own (Crouse, et al. , 1981). The second type of legislation, mandatory reporting of elder abuse, generally requires health care and other professionals to report cases of suspected abuse to appropriate authorities. Yet, there is little standardization of "...the criteria for emerging intervention and the protecting of due process rights..." across states (Kosberg, 1986). Kosberg points out that usually "legislation provides [for] legal action against anyone who, knowing of elder abuse, fails to report it." But, there are few, if any, due process protections for the abused persons. Mandatory reporting has been criticized because of its ineffective¬ ness in reducing elder abuse and its failure to protect the personal liberties of the abuse victim (Salend, Kane, Satz, and Pynoos, 1984; Faulkner, 1982). Mandatory reporting has also been criticized as an "inexpensive (but showy) way for the state to deal with the problem and, thus, demonstrating] an effort to deal with a problem that will not cost a great amount of state revenue" (Kosberg, 1986). Additional problems exist. One such problem is the lack of aware¬ ness of the legal requirement that certain groups report cases of elder abuse. O'Brien (1986) surveyed physicians in Michigan and North Caro¬ lina, and found that 70 percent of physicians were unaware of elder abuse reporting requirements, even though about 25 percent of these physicians had previously encountered a case of elder abuse. In a random survey of physicians in Alabama, Daniels, Baumhover, and Clark-Daniels (1989) reported that 72.3 percent of the respondents were unclear as to how to report cases of elder abuse even if they did recognize that abuse had occurred. In Alabama, 41.9 percent of these same physicians had seen abuse in their practices. The literature on nurses and elder abuse is sparse . Available literature suggests that recognizing and helping abuse victims is a vital part of nursing (Hirst and Miller, 1986). Furthermore, the literature suggests that nurses are required to report abuse, neglect, or exploitation, when mandatory reporting requirements exist. Several authors (c.f. Brent, 1988; Thobaben and Anderson, 1985) note that nurses are part of the medical profession who are mandated to report abuse. 244 Registered nurses and the reporting of abuse Three years ago, nurses in Canada were concerned because there was no mandatory reporting law in "any of the provinces..." (Hirst and Miller, 1986). Unfortunately, little research has been done on the nurses' responses to these requirements. This article attempts to fill this gap for registered nurses in Alabama. The Alabama Law In Alabama, Act No. 780 was enacted in 1976 to protect all persons over the age of 18 who were in need of protective services. The Act required the reporting of cases of abuse, neglect, and exploitation to the Department of Human Resources (county welfare department) by "prac¬ titioners of the healing arts." The act did not define "practitioners". The penalty for not reporting suspected cases of abuse, which was $500 or six months in jail, is the same penalty for abusing an adult.1 The Department of Human Resources (DHR) was required to investigate within 72 hours of the initial report. In May 1989 (Alabama Senate Act 337) , this law was amended to make the act of abuse, neglect, or exploitation a felony punishable, in some cases, by a maximum 20-year prison sentence and a maximum fine of $10,000. Emotional abuse remains a misdemeanor. However, "practitioners of the healing arts" were not further defined and, the fine for not reporting such cases remained the same ($500) . The amendment allows any person in the state to report if they so choose. Reporting by other than "practitioners of the healing arts" was occurring even without the official status given by the amendment. Since 1976, there has been an increase in reported cases of adult abuse. For instance, during 1984, there were 4,171 cases of abuse, neglect, or exploitation reported in the state. In 1988, over 7,200 reports were received by DHR. Based on reporting in 1989, it is ex¬ pected that over 9,000 cases will have been reported by September 30, 1989. These reports include all reported cases of abuse, neglect, and exploitation of both disabled adults and older adults. The Purpose of this Study This research is part of an ongoing project to examine the under¬ standing and attitudes of Alabama health care providers concerning three important components of public policy toward elder abuse: understanding and diagnosis of elder abuse, neglect, and exploitation; knowledge of and attitudes toward the Alabama Adult Protective Services Act; and possible barriers to the willingness to report. The initial study covered Alabama physicians in the specialties most likely to encounter elder mistreatment: family practice, general prac¬ tice, and internal medicine. The study concluded that, while physicians evinced considerable knowledge about elder abuse, they clearly were not aware of the law and its operation, nor were they very willing to report cases of abuse (Clark- Daniels , 1988; Clark- Daniels , Baumhover, and Daniels, in press; Daniels, Baumhover, and Clark- Danie Is , 1989; Daniels, Clark-Daniels , and Baumhover, 1988). 245 Clark-Daniels The current study shifts the focus to registered nurses. Of the several classifications of health care providers likely to come into contact with elder mistreatment, nurses are among the most likely to make the initial contacts with the patients. This front-line position is especially the case for nurses specializing in home health and community health care (Brent, 1988). Many of these nurses frequently work with the elderly in the patient's home. They may see neglected or abused persons before the physician does. A physician is likely to see the elderly patient after the person is dressed up and made ready for a visit to the physician's office. The Sample The research population for this study consisted of home health and community health nurses. As of July 1988, the Alabama Board of Nursing listed 1,539 registered nurses in these specialties. A two-page mail questionnaire was administered to the entire universe in late July 1988. Return envelopes were included. Two weeks after the initial mailing, a reminder postcard was mailed to boost response. The master list of reg¬ istered nurses provided by the Alabama Board was unusually complete and up-to-date. Less than 10 of the surveys were returned as undeliverable, and only 4 percent of the respondents indicated that they were retired. By comparison, the Alabama Medical Association list of licensed physi¬ cians used in the previous study yielded a higher rate of undeliverable letters, and a retirement rate of 20 percent (Clark-Daniels, 1988). Of the 1,539 surveys sent, 462 (or 30%) were returned. The response rate is low, but is not at all unusual for mail questionnaires to pro¬ fessional populations. O'Brien (1986) achieved a 30 percent response rate for his elder abuse survey of physicians in Michigan and North Carolina. The authors achieved a 46 percent response rate for a random 12 percent sample of the population of Alabama general practitioners, family practitioners, and internists. Even taking into account the high rate of retirement for the physicians survey, the usable response rate was 35 percent. Thus, the nurses' response fit within these boundaries. However, the low response rate does bias the conclusions to an un¬ determined degree. Unfortunately, the respondents and non- respondents cannot be compared demographically because no state -wide demographic data are available for these two nursing specialties. Strictly speaking, therefore, the conclusions of this study should be limited to the 30 percent who responded. Some speculations about the direction of bias are possible. In particular, the nature of the study and previous research on the biases of mail questionnaires suggest that the nurses who responded to the survey are likely to be those most interested in the topic. These nurses are more likely to be those who have seen and reported abuse, neglect, or exploitation. As a result, the survey probably overestimates the percentage of the registered nurses in Alabama who have seen and reported abuse and will generally not be useful in evaluating the extent of abuse. The possible bias with regard to the attitudes of the nurses to the three main areas of the study is impossible to determine. 246 Registered nurses and the reporting of abuse The Questionnaire The survey instrument was developed from the instrument used for the physician study in 1987. Both the earlier instrument and the draft in¬ strument for the nurses' study were pretested. The instrument sent to the physicians also served as a pretest for the survey mailed to the nurses. A modified instrument was then sent to select registered nurses, physicians, and academics associated with the College of Behavioral Sciences at the University of Alabama. Based on their suggestions the instrument was further revised and sent to the population of home health and community health registered nurses. The key difference between the physician instrument and the nurse instrument was the focus of the nurses' instrument on the reporting of elder abuse, neglect, and exploitation, and the reasons for not reporting. The nurses' questionnaire contained demographic items (age, sex, and race), characteristics of practice occupation, years in practice, retirement status, patient load, and proportion of senior citizens among patients. Questions concerning the identification and reporting of elder mistreatment, scales dealing with the understanding and diagnosis of abuse, knowledge of the Alabama law, and willingness to report abuse were also included. The identification and reporting section of the questionnaire asked the respondent to identify whether they had come across cases of abuse, and if so, how many in the past year and in their career. They were also asked to respond to a similar set of questions with regard to reporting cases of abuse. In addition, they were asked to identify the agency to which they reported and their satisfaction with the response. Non¬ reporters were asked to list the reasons for not reporting. The final section of the survey consisted of 31 statements on the definition of abuse, the understanding of the law, and the willingness to report. The respondents were asked to evaluate these statements on the basis of a five -point Likert- type scale ranging from Definitely Not True to Definitely True. For the purposes of this report, the scales were collapsed into three-point scales, Not True, Unsure, and True.2 Results of the Study Table 1 presents the demographic information and practice charac¬ teristics of the survey respondents. Because some nurses did not list home health and community health as areas of specialty, nurses who stated that they were in administrative, mental health, hospital emergency room, and other positions, or simply did not give any specialty, were catego¬ rized as "other" . The average ages of the three groups of nurses were not very different. The typical home health nurses were 40.6 years of age, community health nurses 42.6, and other nurses 40.9. A large majority of the nurses were white and female. There was some variation in the average number of years the nurses had spent in their profession. Home health care nurses in this survey had the least experience (6.3 years), followed by other nurses at 9.2 years. Community health nurses averaged 11.9 years in their profession. 247 Clark-Daniels Table 1.

The home health care nurses saw the fewest patients per day but the highest percentage of patients over the age of 65. There was a progres¬ sion from highest (home health) to lowest ("other") among both those who 248 Registered nurses and the reporting of abuse have seen abuse and those who have reported abuse. Home health nurses saw a higher percentage of abuse in their patients in the past year and in their careers. "Others" saw the least and reported the least abuse. Community health nurses were most likely to have both seen and reported abuse in the past year (46.1% / 53.5% - 86.2%). Home health nurses were more likely to have seen and reported abuse in their careers (76.5% / 85.6% - 89.4%). Other nurses reported startlingly few of the cases of abuse they had seen, 26.3% in the. past year and only 62.2% in their career. The source of this gap in reporting is not clear. The community health nurses were the most satisfied with the handling of cases once abuse was reported to authorities. Even so, the satisfaction measure for all three categories was low. For example, only 36.0% of the community health nurses were satisfied with the handling of reported cases . Despite the dramatic differences in encountering and reporting abuse, few differences existed across groups in the understanding and diagnosis of abuse (see Table 2). Home health and community health nurses shared common points of view. Other types of nurses were slightly more likely to be uncertain about the definition and diagnosis of abuse. Most nurses disagreed with the statements that few older people were abused or neglected. Most also believed that the abuse which physicians saw was only the tip of the iceberg, although the "other" category was slightly more likely to disagree. There was confusion concerning the existence of clear-cut definitions of abuse given by professional associations and whether most abuse involved only minor injuries. In addition, Diagnostic Related Groups (DRGs), according to a plurality of the nurses, have contributed to mistreatment of elderly patients in some cases. Still, many of the nurses expressed uncertainty or disagreement with this evaluation of DRGs. In general, though, a majority of nurses in all categories believed that experienced people in their profession could accurately detect cases of elder abuse. Many of the nurses did not fully understand the legal responsi¬ bilities imposed by the law (Alabama, 1976), especially the handful of nurses not identified as home health and community health. On the one hand, over 90% of the nurses in all categories responded that all health care providers had a legal responsibility to report elder abuse. Over 90% also disagreed with the statement that only physicians were required to report. On the other hand, most of the nurses in all categories were confused about whether an older adult could be removed from their home without his or her consent (see Table 3). Moreover, less than 7% of the nurses in all three categories believed that Alabama had sufficient services available to meet the needs of abused elderly people once the legal process of intervention had begun. Most of the respondents were also uncertain about the protections and penalties of the law. There was concern about whether anonymity could be guaranteed to any health care provider who reports cases of elder abuse. Additional confusion arose over protection from litigation. A plurality of all groups were unsure of legal protection even though the law provides 249 Clark-Daniels Table 2.

The same uncertainty was shown in the responses to a potential fine or jail sentence. The law states that the fine for not reporting is $500, and there is a jail sentence of up to 6 months for not reporting abuse, neglect, or exploitation (Alabama, 1976). 250 Registered nurses and the reporting of abuse Table 3.

Table 4 reports these responses. Again, responses varied little across specialties. Most of the nurses agreed that it was their responsibility to report abuse. A majority in all three catego¬ ries of nurses actually believed that they did not have to be absolutely certain abuse has occurred before reporting it. Even so, over 30% of the respondents in all groups reported that they had to be sure abuse had occurred. Over 50% of the respondents said that they would find the possibility of a lengthy court appearance to be a barrier to reporting abuse. Nevertheless, over 80% of all respondents would not want to handle cases of elder abuse themselves. Most believed that reporting abuse would make the abuser angrier and that the families of the victims of abuse would find out that they were the ones who had reported abuse. These same respondents believed that the victim would deny that abuse had happened. Still, over 74% of the respondents were either unsure or did not believe that their relation¬ ship with the patient would be damaged if they reported abuse. Conclusions Clearly, there is much confusion and ignorance about elder abuse legislation in Alabama. This uncertainty is not unique to either the particular categories of nurses surveyed or to the state. Physicians in Alabama who were surveyed in 1987, demonstrated this same confusion (Daniels, et al., 1988). Although nurses were fairly certain of their ability to detect abuse, they were unsure about important aspects of the law, and displayed considerable disillusionment with the effectiveness of reporting. These data demonstrate that nurses, who are often among the first non- family members to become aware of abuse or neglect, are ambivalent about reporting when these cases arise. Misconceptions remain concerning the meaning of the law, the degree of legal protection provided, and the degree of certainty required before abuse is reported. For this and a variety of other reasons, there is probably signifi¬ cant under reporting in Alabama. The mandatory reporting feature of most state laws has probably increased the awareness of abuse and neglect. The fact that over 90% of home health and community health nurses and 76% of the "other" nurses in Alabama knew that the appropriate agency for reporting cases of abuse was the Department of Human Resources reflects the increase in awareness. It is likely that more cases of abuse are being reported than ever before. Yet, it is not possible to truly measure the effectiveness of the law because unreported abuse of some magnitude still exists. Increases in reported cases may simply mean that more new cases of abuse are occurring that particular year than in previous years. Thus , human services workers may never be given the opportunity to deal with any but the worst cases of abuse or neglect because these cases are so obvious and demand immediate attention. There are still other difficulties for public administrators. The mandatory reporting law in Alabama and in many other states does not seem to give the necessary pro- 253 Clark-Daniels cedural guidelines which will actually protect the rights of elderly adults. Nor has the law been well publicized among health care providers. And even for those who know of the law, the law's provisions are not well understood. This survey demonstrates that nurses who are required to report cases of abuse or neglect are reluctant to invoke the law. The law in Alabama is now 12 years old and not many in the population of the state actually know what the law provides. Public administrators and human services workers could do considerably more to make the law and its amendment known to caregivers in the state and to help medical professionals define the meaning of the law. One of the key weaknesses of the law is in the area of services . The nurses in the survey were uniform in their belief that social services for the elder abuse victim in Alabama are inadequate. This lack of services is particularly damaging, as it imposes a cruel choice on DHR social workers : institutionalization or no intervention.3 Furthermore, protective services provided for elder adults are often sparse, particularly in rural areas. In rural areas, health care pro¬ viders may not know if there are any services available beyond nursing homes. This can serve to frustrate those who are required to report abuse. Even though relocation to an institution may clearly obviate the need to report further abuse, it may not be the best solution for the victim. For instance, the home where the abuse occurred is often owned by the victim and the abuser may be living there in order to care for the victim. It would seem that the removal of the abuser would leave the elder person less vulnerable than the removal of the victim. This requires the development of alternative in-home services. The law offers no guidelines on this point. Abuse and neglect of the elderly are a continuing problem that will not go away with the passage and implementation of new punitive laws. Mandatory reporting laws alone cannot prevent abuse or even reduce the problem. Laws tend to be punitive toward both the abuser and the abused as well as toward the non-reporting physician. Problems of abuse are particularly difficult when the abuser is a family member, as is often the case. Currently, most social and economic support of the aged is derived from family members. Elderly persons depend on this support even if their family members are the ones committing the abuse , The elderly person needs this support and expects that this support will continue even if abuse occurs . Beyond the immediate problem of abuse, all of us are growing older and want to lead productive lives without facing abusive situations. Punitive laws can protect us to some extent, but can deprive us of control over our lives. Moreover, the lack of guidance and coordination among professions most likely to encounter elder abuse makes the application of existing law sporadic and arbitrary. The lack of knowledge about existing law and lack of a common frame of reference in dealing with elder abuse is clearly apparent among some Alabama nurses . What is needed now is a more 254 Registered nurses and the reporting of abuse comprehensive education program for those professionals most likely to encounter abuse. A further demand for creative programs designed to meet the unique requirements of an aging population needs to be met. ENDNOTES ’The starting age for "older adults" is uncertain. The Alabama Depart¬ ment of Human Resources (DHR) considers adults 50 years and older to be older adults. Others in the state and American Association of Retired People (AARP) define the age as 55 years of age. The United States Social Security Act of 1935 uses a retirement age of 62 years for early retirement and 65 years for the beginning of normal retirement and the beginning of the "older years." This article, and the survey on which it is based, used 65 as the cut-off point. 2Despite the complexity of the statements, most of them appear to fit reasonably well within the three categories: understanding and diag¬ nosis of abuse, understanding of the mechanics and operation of the law, and the willingness to report abuse and neglect. A factor analysis of the 21 statements revealed 12 factors. Thus, each of the categories was multidimensional; however, the overlap across categories was minimal. At most, only eight of the scales loaded on more than one factor or on no factors at all. Moreover, most of the factors were associated with primarily one category of scales. Only four of the twelve factors could not be unambiguously identified with one of the categories. 3The lack of services has become a real problem Even institutional¬ ization is not always a possibility because there simply are not enough nursing home beds available for those on Medicaid or who are unsponsored and not private pay patients in Alabama. At least some of the abused elderly are unable to pay to live in any other situation than the place they currently reside. This is a particularly difficult situation when the abused elderly person's abuser also lives in the same household. REFERENCES Alabama (1977). Adult protective services act of 1976.

TRICHOSTRONGYUJS COLUBRIFORMIS (NEMATODA) INFECTION IN NORMAL AND ZINC-DEFICIENT GOATS1 Leon W. Bone USDA, ARS Animal Parasite Research Laboratory P. O. Box 952 Auburn, AL 36830 and Edward J. Parish, Waite Dykes, and Herbert H. Kohl Department of Chemistry Auburn University Auburn University , AL 36849 ABSTRACT Goats infected with the intestinal nematode, Trichostrongylus colu- briformis , gained less weight than uninfected animals. Infection of zinc- deficient animals caused a weight loss while uninfected goats, given deficient feed, gained insignificantly. Loss of body weight was independ¬ ent of infection level. Levels of serum zinc declined in deficient- ration animals by 71% while zinc levels in the intestinal nematodes declined by 35%. Infection with various levels of nematode larvae indicated no effect on the zinc status of the host. INTRODUCTION The importance of dietary zinc is recognized in both man and ruminants (Hambridge, 1981; Blackmon et al., 1967). The role of zinc during infec¬ tion has been reviewed (Sugarman, 1983) , but few studies have examined the relation of zinc levels in the host and helminth disease. Plasma levels of zinc are reduced in human schistosomiasis while zinc supplementation reduces the schistosome burden in hamsters (Mikhail and Mansour, 1982; Mansour et al., 1983). These studies suggest an interaction of zinc status and helminthiasis. Helminths may also require trace levels of zinc. The zinc -dependent enzyme, leucine aminopeptidase , may be involved in both hatching of eggs and exsheathment of larvae of Haemonchus contortus (Rogers, 1982). Addi¬ tionally, schistosomes and their eggs concentrate zinc from the environ¬ ment of the host (Booth and Schulert, 1968). This study examined the influence of the ruminant nematode Tricho¬ strongylus colubriformis on growth and serum levels of zinc in normal and zinc-deficient goats. Zinc content of the parasite was determined also in these hosts. ’Manuscript received 15 May 1989; accepted 6 June 1989. 257 Bone, Parish, Dykes, and Kohl MATERIALS AND METHODS Male, cross-bred goats, 10 to 12 weeks of age at infection, were weighed and placed in cages. Normal animals were fed a grain mix, hay- pellets and tap water that contained adequate levels of zinc. Two animals were held as uninfected controls while five additional goats were infected orally with 10, 25, 37.5, 45, or 65 x 103 larvae of Trichostrongylus colubriformis . Zinc deficiency was induced in another group of six goats. Animals, 6- to 8-weeks old, were given a zinc -deficient diet (1.05 ppm; ICN) and reagent-grade water (Milli-Q; Millipore Corp.). Zinc was not detected by atomic absorption spectrophotometry in the reagent-grade water. The zinc- deficient diet was formulated according to Neathery et al. (1973). After 1 month for zinc depletion, four animals were infected orally with 10, 25, 35, or 50 x 103 larvae of T. colubriformis . Two goats were held as con¬ trols. Animals in both groups were weighed at biweekly intervals to determine the mean percentage of weight change, relative to their previous weight determination, over a 12-week period. Blood was taken by veni¬ puncture at biweekly intervals and allowed to clot overnight. The mean content of zinc (ug/ml) in the serum was determined during the 12 -week period by atomic absorption with a Perkin Elmer Model 103 spectrophoto¬ meter versus standards (1974, Analytical Methods for Atomic Absorption Spectrometry, Perkin-Elmer Corp., pp. 5-20). Stainless steel cages and feed or water containers were used throughout the study to eliminate the availability of zinc in the host's environment. Animals were given normal food and water or zinc-deficient food and water ad lib. Normal and zinc-deficient animals that were inoculated with 25 x 103 larvae were killed after 12 weeks for recovery of nematodes in a Baerman apparatus. Worms were rinsed repeatedly with reagent-grade water, weighed, and digested with warm, concentrated nitric acid. Digestion of the helminths was completed with perchloric acid at 200 C. Zinc content (ug/g) of the acid background and triplicate samples of helminths were determined by atomic absorption as described above. Data are given as mean + SEM. Data were evaluated by Student's t- test, analysis of variance, and linear regression. The 0.05 probability level was considered significant. RESULTS Infected goats on normal feed gained significantly less (F - 12.52) than the uninfected controls (Fig. 1). Mean gain in weight decreased linearly (r - 0.90) as the larval inoculum of T. colubriformis was increased. Weight gain in the animal that was given 65 x 103 infective larvae was only 36% of the uninfected controls; however, all infected animals exhibited some weight gain during the study. In contrast, little weight gain (0.9%) occurred in the uninfected animals that were given zinc -deficient feed (Fig. 2). Zinc-deficient animals that were infected with T. colubriformis lost significant weight (F - 41.88) during the study. Loss of weight was independent of the dosage of larvae (r - 0.13). Infection by T. colubriformis had no appar- 258 Trichostrongylus colubrlformis infection in zinc-deficient goats Figure 1. Percent change in weight (mean + SEM) of goats that were given normal feed and were uninfected or infected with the indicated dosage of T. colubrlformis larvae during a 12 -week period. ent effect on the level of serum zinc in goats on either feed (Fig. 3). The level of serum zinc was significantly less (F - 17.65) in animals on zinc-deficient rations. The zinc content of T. colubrLformls was altered significantly (p < 0.05) by their host's status. Helminths from animals on normal feed contained 2.23 (+ 0.32) ug of zinc/g dry body weight while those from zinc-deficient animals had 1.44 (+ 0.18) ug/g dry body weight. Worms from zinc -deficient animals appeared morphologically normal and produced patent infections, based on fecal examinations. Viable third-stage larvae were recovered from fecal-spagnum moss cultures. DISCUSSION Infection of goats with T. colubrlformis had no apparent influence on the level of serum zinc when an adequate dietary source of zinc was produced. In contrast, plasma levels of calcium decline in sheep after 3 weeks of Infection by T. colubrlformis (Coop et al., 1976). The infected animals showed significantly less weight gain than the uninfected controls. Also, infection with T. colubrlformis apparently contributed to weight loss in zinc-deficient animals. The absence of a 259 Bone, Parish, Dykes, and Kohl Figure 2. Percent change in weight (mean + SEM) of goats that were given zinc-deficient feed and were uninfected or infected with the indicated dosage of T. colubriformis larvae during a 12 -week period. dose -dependency of larvae to weight loss suggests that fewer helminths (less than 10,000 larvae) affected the host when the helminth infection was superimposed on the zinc deficiency. Coop et al. (loc. cit.) reported a 50% reduction in weight gain by sheep with 17,500 larvae of T. colubri¬ formis while Steel et al. (1980) found that 9,500 T. colubriformis caused a 39% decrease in the sheeps' weight gain. The 35% reduction in total zinc in T. colubriformis while the host's serum declined by 71% during a dietary deficiency of zinc suggests a successful competition by the helminths for available zinc. Our interest in this facet originated with reports that various nematodes contain comparatively high levels of zinc for animal tissue (Deuhert and Gray, 1974) and the occurrence of zinc sulfide in the often-described calcium 260 Trlchostrongylus colubrlformis infection in zinc-deficient goats Figure 3.

However, the lack of any effect of increasing larval dosages on the host's level of serum zinc indicated that zinc uptake by the parasite contributed little to the nutritional deficiency in the goat.

ABSTRACTS HEALTH SCIENCES NEW MEDICAL QUALITY ASSURANCE PROGRAM FOR THE DEPARTMENT OF DEFENSE. Robert E. Pieroni, Dept, of Internal Medicine and Family Medicine, Univ. of Ala., Tuscaloosa, AL 35487. In 1985 the Department of Defense (DOD), in its continued efforts to provide optimal patient care to patients in its world-wide medical treatment facilities, instituted a plan for external civilian peer review. Written standards were developed by a multidisciplinary advisory panel, and abstracted data from medical records (approximately 8% of total hospital discharges) were compared with criteria-based computer algorithms. In general, less than 1% of the medical records sampled failed to meet quality assurance criteria. Two areas of concern involved treatment of diabetic ketoacidosis, and decisions concerning need for hysterectomy. I shall discuss this innovative system which has been designed to improve medical and surgical care of DOD beneficiaries, as well as its potential application for civilian medical facilities. Specific examples of the functioning of the quality assurance program and its benefits in improving patient care will be described. ALCOHOLIC KETOACIDOSIS. Jim Zumstein and Robert E. Pieroni, College of Community Health Sciences, Univ. of Ala., Tuscaloosa, AL 35487. Alcoholic ketoacidosis (AKA), a disorder of carbohydrate metabolism, was first described in 1940. Patients are usually chronic alcoholics who have been on a recent "binge," but, because of nausea and vomiting, anorexia, and abdominal pain, often have not taken food or alcohol for one to three days before hospital admission. Although serum glucose is usually slightly elevated, patients, not infrequently, are euglycemic or actually hypoglycemic. Even though it has been estimated that for every four cases of diabetic keto¬ acidosis there is one case of AKA, the majority of AKA cases are not correctly diagnosed. Because of an increased beta-hydroxybutyrate acid to acetoacetate acid ratio, the nitroprusside reaction, used to determine ketones, may be negative, thereby obscuring the diagnosis of AKA. We shall present the case of a female with classic manifes¬ tations of AKA, and discuss the characteristics of this disorder, including pathophysiology, clinical and laboratory findings, differential diagnosis, potential complications, and appropriate therapy. 263 Abstracts THE WHITE CLOT SYNDROME. Robert E. Pieroni , Dept, of Internal Medicine and Family Medicine, Univ. of Ala., Tuscaloosa, AL 35487. Heparin-induced thrombocytopenia is felt to be the most important idiosyncratic drug-induced thrombocytopenia because of its frequency (occurring in about 5% of patients) and its less common, yet potentially devastating, association with hemorrhage, as well as systemic thrombosis. Heparin has been in use as an anticoagulant for about 50 years, and its capacity to induce severe arterial thrombosis has been documented in a variety of reports for over a decade. Heparin-induced thrombocytopenia and thrombosis (the "HITT" or "White Clot Syndrome") most often occurs after a patient has received heparin for six days or more. However, in a previously exposed patient, the syndrome can develop in hours or days. This syndrome has occurred following administration of heparin by any route and at any dose. Heparin-IgG immune complexes are considered important in the etiology of this disorder which can result in strokes, amputa¬ tions, myocardial infarctions and other severe thrombotic events. We shall review the literature and discuss case reports pertaining to HITT. Emphasis will be directed toward proper use and monitoring of heparin in order to prevent the white clot syndrome and reduce potential complications during heparin utilization. ABNORMAL CHOLESTEROL VALUES: CLINICAL VIGNETTES. Robert E. Pieroni, Dept, of Internal Medicine, Univ. of Ala., Tuscaloosa, AL 35487. Increasing attention continues to be given to serum cholesterol as a major risk factor for coronary heart disease (CHD). The relatively high prevalence of CHD in this country has been convincingly associated with high cholesterol levels. It has been demonstrated that in high- risk hypercholesterol emic patients each 1% reduction in total serum cholesterol is associated with a 2% decline in CHD. Although prudent diet remains the cornerstone for lowering serum cholesterol, other risk factors (e.g. sedentary living habits, hypertension, stress, diabetes, smoking) should also be modified in order to lower CHD risk. We shall review recent recommendations on treatmet of hyperlipidemia emphasizing diet, exercise and use of medications that can diminish harmful low density lipoproteins (LDL) , and potentially elevate high density lipoproteins (HDL) - the so-called "good cholesterol. Several clinical vignettes will be presented which underscore the importance of evaluating lipid profiles, as well as use of appropriate methods to lower CHD in dyslipemic subjects. 264 Journal of the Alabama Academy of Science, Vol. 60, No. 4, October 1989.

Richetto Department of Geography The University of Alabama Tuscaloosa , Alabama 35487 and D. Michael Henderson Department of Geography The University of Alabama Tuscaloosa , Alabama 35487 ABSTRACT Since the mid 1950s there has been a significant spatial reorgani¬ sation of human and economic activities within the American city. In response to the continuing suburbanization of the urban population; retail and commercial activities have decentralized. In the wake of this aban¬ donment several office and service -related functions have found the rental opportunities in the central business district attractive. In order for local government and booster organizations to more effectively target their resources for reinstating the economic base of the central business district, it is necessary to identify those traditional tertiary activi¬ ties responding to decentralizing forces and those quaternary activities that are sensitive to the centripetal forces operating within the CBD. Within this context, this study (1) traces the extent of retail/commercial decline in the central business district, (2) examines the in-migration of office and service -related functions into the central business district, and (3) investigates the extent to which the availability and pattern of low-cost rental opportunities affect the spatial distribution of retail and office activities. The City of Tuscaloosa, Alabama serves as a case s tudy . INTRODUCTION Since the mid 1950s there has been a significant spatial and functional reorganization of human and economic activities within the American city. The centrifugal movement of residential, retail, and commercial activities away from the central business district (CBD) towards the urban fringe and beyond has been widely documented (Andrews , 1962; Hoyt, 1968; Murphy, 1974; Taeuber, 1974; Gale, 1982; Brown, et al. , 1982; Schwartz, 1984). Numerous spatio-economic and socio-political processes have served as push-pull factors resulting in the massive exodus of residential and retail activities from the CBD. However, in the wake of such abandonment, a centripetal movement pattern has emerged as several ’Manuscript received 5 June 1989; accepted 25 July 1989 . 1 Richetto and Henderson office-related functions have found the increasing number and lower cost rental opportunities in the central business district attractive. Within this context the primary purpose of this study was fourfold: (1) document the extent of retail/commercial decline in the CBD by type of activity and where, in general, relocation occurred; (2) identify factors underlying such decentralization; (3) investigate the increasing attraction of the CBD for the location of office activities; and (4) examine the trends of commercial rental opportunities in order to project the future locations of retail and office activities. Although the city of Tuscaloosa, Alabama served as the case study to evaluate empirically these objectives, it is necessary and informative to discuss CBD function¬ al reorganization in its most general form. CBD FUNCTIONAL REORGANIZATION Since the early 1960s considerable attention has focused on central business districts throughout the United States; particularly functional land-use changes occurring within these areas associated with increasing suburbanization. Several studies have attempted to determine the extent and nature of this functional change, specifically the decline in retail/ commercial activity (Rannells, 1956; Cox, 1967; Bowden, 1971; Davies, 1984) and more recently the locational patterns of office functions (Armstrong, 1972; Black, et al., 1982; Bateman, 1985). As early as 1932, Rolph noted that the four most important factors determining the location of retail and commercial activities were popula¬ tion, income, transportation, and topography. Five years later, Proudfoot wrote: "the central business district represents the retail heart of the city". Historically, such a characterization of the CBD was accurate. The central business district served as the nucleus of the American city; it functioned as the terminus of major transport systems and provided the most central and accessible location for commerce, industry, and govern¬ mental activities. The end of World War II, however, signalled the beginning of an era of near cataclysmic change in urban spatial patterns. Transportation, population density, and the geography of household income underwent profound change. The nation's urban population increased from 20% in 1860 to nearly 75% in 1980 (Figure 1). As a result, the compact prewar city grew into the postwar suburban spread city. Perhaps the most important factor contributing to the modern day, spread city was the automobile and its attendant highway development. Between 1940 and 1980 automobile ownership increased from 27.3 million to 120.9 million; a 343% increase. This mode of transportation provided a more flexible and quicker means of movement, therefore, opening up areas for development which were once considered too distant. As a result, the geography of residential development shifted ever outward away from the CBD, creating retail market opportunities that before were nonexistent (Figure 2). Between 1960 and 1970 the increase in population of areas outside the central city in major metropolitan areas exceeded that of the central city, indicating that the relative significance of the central city for residential development was declining. Other evidence in support of this 2 Spatio-functional reorganization within urban areas Figure 1. Percent of the United States population in urban areas, 1960-1980. YEARS Figure 2. Population of central cities and outside central cities for United States SMSAs , 1950-1980. functional reorganization occurring within the American city includes the locational trends of retail stores. In 1967, for example, 12,682 stores were operating in major cities across Alabama, of which nearly 1,200 or 9.2% were located in the CBDs. By 1982, the total number of stores in¬ creased to over 17,500; however, the number located in the CBDs decreased to less than 1,000 or 5.7%. Several national-based studies concur with the above Alabama statistics noting significant residential and retail 3 Richetto and Henderson abandonment of the CBD (Simmons, 1964; Murphy 1974; U.S. Department of Commerce, 1980; Johnston, 1984). In the wake of the continued residential and retail abandonment of the CBD (thereby vacating large amounts of available floor space), the declining level of competitive use for land within the CBD, and the trend toward functional separation within large businesses; an increasing number of comparatively low cost rental opportunities has emerged in the CBD. In turn, the office sector which has developed as an outgrowth of the spatial separation of clerical, administration, and executive functions has been increasingly attracted into the CBD in growing numbers (Ginzberg, 1974; Stanback, 1976; Sim, 1982; Bateman, 1985). Finally, although nearly every type of retail/commercial activity has responded to the centrifugal forces of suburbanization, not all office functions have found the CBD to be a favorable location (Table 1) . Those office functions where external personal contact and access to public documents is critical and decision making and negotiation requires face-to-face communication; the amenities associated with the central business district become increasing-ly important in the location decision.

Downtown Office Growth and the Role of Public Transit, 1982. Therefore, by examining the trends of both retail and office activities and their respective roles in reorganizing the functional landscape of the American city, local governments may better understand those factors causing functional change within the CBD before determining that retail decline is worthy of the massive investment necessary to reverse this phenomenon. The city of Tuscaloosa serves as a data base for examining the extent and nature of CBD functional reorganization. THE CASE STUDY The city of Tuscaloosa is situated on the Black Warrior River in West Central Alabama and is the fifth largest urban area in the state, with a 4 Spatio- functional reorganization within urban areas population of nearly 100,000. For the purpose of this study Tuscaloosa is defined as the urbanized area of Tuscaloosa County, including the incorpo¬ rated cities of Tuscaloosa and Northport, and the unincorporated urbanized areas of Tuscaloosa County (Figure 3). Between 1940 and 1980, the total population of Tuscaloosa County increased from 76 thousand to over 137 thousand, an increase of 81%. During the same period the urban population of Tuscaloosa increased from 40.3% to 72.4% of the total population. As Tuscaloosa's population increased, most of the residential expansion oc¬ curred along the urban fringe. Such outward movement of the population away from the CBD, along with the development of an integrated transport system and changes in retail marketing strategies, also facilitated the decentralization of the retail sector. This decentralizing trend began in Tuscaloosa as early as 1960 with the development of the Parkview Shopping Plaza located two miles east of the central business district. Subsequent to this development, several other suburban-oriented retail districts have developed and continue to develop at ever-increasing distances away from Tuscaloosa's CBD (Table 2). Figure 3. The urbanized area of Tuscaloosa, Alabama. In reference to the above general trend describing Tuscaloosa's retail sector, the remainder of this paper explores the hypothesis that the city 5 Richetto and Henderson Table 2.

Specifically, Tus¬ caloosa's central business district no longer serves as the city's primary area of retail and commerce; rather it has become an area predominated by office and ancillary activities. THE METHODOLOGY A list of business establishments was compiled including retail and office activities found in the urbanized area of Tuscaloosa (Table 3). Although the list is composed of general functional classifications, it is limited to those functions which have in the past or are presently locating in Tuscaloosa's CBD. A base map was constructed consisting of a series of concentric zones centering on Tuscaloosa's peak value inter¬ section (Figure 4). In an effort to document the spatial and temporal trends in retail and office location patterns, the radius of each succes¬ sive concentric zone was increased by one-half mile; thereby dividing the city into 9 zones. In turn, each zone was identified by its predominant function. Table 3. Retail and Office Functional Classifications in Tuscaloosa.

Finally, in order to examine the interrelationship between retail outmigration and office inmigration into the CBD, data were collected on available rental opportunities from the Sunday edition of the city's newspaper between January 1985 and January 1986. Rental opportunities were divided into retail and office and both were plotted on the study’s base map so as to determine the number and average rental price for each zone . Although all of the above tasks were performed for each retail and office activity identified in Table 3, the remainder of this paper will discuss, in detail, one retail (clothing) and office (lawyer) activity and then present summary findings for all other activities. RETAIL/OFFICE ACTIVITY ANALYSIS Between 1940 and 1983 the total number of clothing outlets in Tuscaloosa increased from 15 to 58 with the largest increase occurring between 1963-1973 when the number of establishments grew by 23 (Table 4). Notwithstanding this dramatic overall increase, there were substantially fewer clothing stores operating within the central business district in 1983 as compared to 1940. In particular, there occurred a significant outward shift in retail clothing establishments between 1973-1983 favoring 7 Richetto and Henderson Table 4.

The most important force underlying this decentralizing pattern was the development of suburban retail districts. Data for 1940 and 1953, a period during which no major shopping center development occurred, reveals that clothing stores were located primarily in the central business district of Tuscaloosa; with only two outlets situated in the Northport zone and one outlet located in the University zone (between 0.6 and 1.0 miles and 1.1 and 1.5 miles from the CBD, re¬ spectively). By 1960, however, the Parkview shopping district was opened (between 1.6 and 2.0 miles from the CBD) and commercial development was occurring along University Boulevard in Alberta City (between 3.6 and 4.0 miles from the CBD) . Data for 1963 indicate that the number of clothing stores opened in these areas was 5 and 3, respectively or 25% of all clothing outlets. In 1969, McFarland Mall opened in the McFarland- Leland zone (between 3.6 and 4.0 miles from the CBD) and subsequently the number of clothing establishments in this zone increased by 12, from 3 to 15. Later, in 1980, the development of University Mall (between 2.6 and 3.0 miles from the CBD) resulted in the largest increase in the number of clothing stores for all concentric zones over any ten-year period. The number of outlets increased by 24, from 2 to 26. During this same time period (1969-1980) the number of clothing stores located within the CBD decreased by more than one-half. Similarly, all other retail functions listed in Table 3 illustrated a decentralizing location pattern, although furniture, jewelry, and florists to a lesser extent (Table 5). In contrast, the location of office-based activities became in¬ creasingly concentrated within the CBD between 1940-1983. In particular, the total number of lawyer offices increased nearly eightfold, from 20 (1940) to 152 (1983). Moreover, not less than 90% of all lawyer offices 8 Spatio- functional reorganization within urban areas 1940 1953 Figure 5. Location of apparel stores in Tuscaloosa, Alabama for select years. were located within the CBD for any given year (Table 6). This sizable and consistent clustering of lawyer offices in the CBD (Figure 6) may be explained by several factors including reduced travel time to and from the courthouse, ready access to both city and county government documents, direct access to other attorneys for council and negotiation, and an abundant supply of low-cost rental space. Office space within the central business district became increasingly available as retail use diminished. The CBD was less than successful in 9 Table 5.

Thus, several office reconversion projects occurred within the CBD (1980-1986) resulting in an oversupply of office rental opportunities. While accountant offices became increasingly concentrated within the CBD; insurance, real estate, financial, and engi¬ neering activities increasingly favored suburban locations in an effort to maximize their community visibility and minimize inconvenience to their prospective clientele (Table 7). 11 Riche tto and Henderson Table 6.

SPATIAL PATTERN OF RENTAL OPPORTUNITIES In 1985 there were 96 retail rental opportunities in Tuscaloosa which were located primarily east and southeast of the central business district (Figure 7). In fact, the CBD contained only 10 or 10.4% of all retail rental opportunities. In contrast, out of 120 office rental opportuni- I — Figure 7.

Because retail activities were decentralized, the average rental price for office space in the central business district became lower than would be expected. That is, the loss of retail establishments from the central business district, in conjunction with a vast number of retail- to-off ice reconver¬ sion projects, and reduced competition, especially from activities capable of high rental bids (e.g., retailers), resulted in a short-term oversupply of low-cost vacant space and a below normal rental market. In turn, the office sector quickly began to establish itself as the predominant func¬ tion within the CBD. Although Tuscaloosa's central business district calculates to be the highest average cost per square foot for office space, by comparison the cost is substantially lower than corresponding retail rental costs in other zones of the city. In these other zones the higher per square foot rental costs reflect greater levels of retail- based competition that is capable of bidding higher prices for use of the land (Table 8). Figure 8.

SUMMARY AND CONCLUSION Throughout the last 40 years the American city has undergone considerable reorganization in human and economic land use patterns. Households have continually shifted their locational preferences away from the central business district and towards the periphery of the built-up city. In response, economic activities, especially retail and commercial, have similarly shifted their site selections. With some major changes, including the development of a suburban- oriented transport system, an 14 Spatio-functional reorganization within urban areas Table 8.

By com¬ parison, office activities have responded positively to the central business district's changing environment. The exodus of retail activity has resulted in an overabundance of vacant space. With reduced competi¬ tion for this space, vis-a-vis retail replacement, there has and likely will continue to be a depressed rental market encouraging office location. Finally, the results of this study may be beneficial to cities which have or are currently experiencing decline in their central business dis¬ trict. Office and retail functions identified as favoring a CBD location may be targeted for incentive programs, ensuring that those already located in the central business district remain and any revitalization efforts to restore the CBD's viability include these functions. Moreover, this study provides a methodology to determine what unique combination of office and retail activities may positively serve the central business district for other cities. In conclusion, local governments must recognize and understand the factors underlying functional change within the central business district before determining that retail decline is a problem worthy of the massive resource investment necessary to reinstate the CBD as the retail heart of the city. Rather, it may be expedient to redefine the primary function of America's central business district as 'central service districts' and allow retail and commerce to respond to the ever changing geography in our cities' market conditions.

A ROVING CREEL SURVEY OF ANGLERS USING GUNTERSVILLE RESERVOIR, ALABAMA: GEOGRAPHIC ORIGINS, SEASONAL PATTERNS OF FISHING EFFORT AND SUCCESS, AND CONTRIBUTIONS TO THE LOCAL ECONOMY’ Robert A. Angus and Ken R. Marion Biology Department University of Alabama at Birmingham Birmingham , AL 3529 4 ABSTRACT This report summarizes the results of a roving creel survey of anglers which was conducted on two creeks on Guntersville Reservoir during spring, summer, and fall, 1987. Spring fishing activity was almost three times as heavy as in summer and fall, with weekend usage much heavier than week¬ days. Most anglers were from northern Alabama. The mean distance driven was 49.6 miles one-way. Each angler spent an average of $8.68 per day for nondurable trip-related goods and services. Based on extrapolation of our data over the entire reservoir, we estimate conservatively that anglers contributed approximately $1.98 million to the regional economy over the three seasons included in the study. Overall, 41.5% of the parties inter¬ viewed indicated they were fishing for bass. Bass fishermen caught nearly 1 bass per hour in the spring and averaged 0.72 bass per hour for the entire year; they released 62.5% of the bass they caught. Fishermen apparently have widely differing expectations of success from a fishing trip on the reservoir; their rating of the fishing quality showed little relationship to the actual numbers of fish caught. INTRODUCTION Reservoirs provide numerous aesthetic, recreational, and economic benefits to American society. These large artificial lakes were estimated to have supported 22% of all freshwater fishing in 1980 and generated total retail expenditures of over $3 billion (Hall, 1985). Effective management of large reservoir fisheries is one of the most important challenges in North American fishery management. The objectives of successful management are (1) satisfactory water quality and fish habi¬ tats, (2) satisfactory fish population structure and dynamics, and (3) satisfactory fish quality as perceived by anglers (Anderson, 1984). It often requires significant expenditure of resources, both of manpower and materials, to ensure that the aforementioned objectives are met. It is easier to present a strong case in favor of preserving the reservoir environment if some reasonable estimates of the extent of usage by anglers and the economic "value" of the reservoir, both as a recre¬ ational and economic resource, is known (Propst and Gavrilis, 1987; Tschirhart and Crocker, 1987). In addition, analysis of the economic ’Manuscript received 13 July 1989; accepted 21 August 1989. 18 Angus and Marion impact of a reservoir can evaluate the significance of sportfishing to economic development and tourism. It can identify the relative contri¬ butions of different kinds of anglers, identify businesses directly affected, and suggest approaches to strengthening the interactions between various sectors of the economy to maximize impact (Martin, 1987). Guntersville Reservoir is a 69,100 acre impoundment of the Tennessee River in northern Alabama near the cities of Guntersville and Scottsboro. Impounded In 1939, the reservoir has enjoyed a national reputation among anglers for its abundant production of quality- sized largemouth bass ( Hicropterus salmoides) , "bream" ( Lepomis species e.g., L. macrochirus , L. mlcrolophus , L. auritus , L. megalotis) , and crappie ( Pomoxis nigro- maculatus and P. annularis) . Fishermen visiting the area to enjoy the fishery have undoubtedly generated much income to the state and local economy by patronizing area businesses such as marinas, fishing tackle/ bait shops, restaurants, and motels. At present, however, the value of the reservoir to the local economy is not precisely known. This report summarizes the results of a roving creel survey conducted on Guntersville Reservoir during the spring, summer, and fall of 1987. The purpose of the study was to obtain information on the numbers of anglers using the reservoir, geographic origins of anglers, the species they were primarily seeking, their success rates, and to estimate the amount of money they contribute to the local economy via expenditures for nondurable, trip- related goods and services. SURVEY SITES AND METHODS Two embayments on Guntersville Reservoir were chosen for study: Spring Creek (lower reservoir) at the city of Guntersville, Marshall County, and North Sauty Creek, (mid reservoir) near Scottsboro, Jackson County. The two embayments are approximately 30 miles apart and represent different regions of the reservoir. The survey areas were selected because they were relatively well-delimited, being bounded by causeways in most in¬ stances. At Spring Creek, an area of approximately 845 acres is delimited by U.S. highway 431 on the upper end and by Marshall Co. highway 67 on the lower. On North Sauty Creek, an area of approximately 2,347 acres was delimited by Jackson Co. highway 11 on the upper end and an imaginary line across the creek at Goose Pond launch at the lower end. Angler surveys were conducted on four days a month during the spring (March-May), and on three days a month during summer (June-August) and fall (September). "Fall" included only one month as funding ceased after September. Each survey began with an instantaneous count of anglers using the predefined study areas. This was done by the clerks travelling throughout the study area in a small aluminum boat. After recording the count of anglers, the interviews were taken. Questions asked of the anglers fell Into three categories: (1) geographic origin of the anglers, (2) expenses related to the fishing trip, and (3) species sought and angling success. The clerks spent a minimum of two hours per site (summer and fall), and considerably more than that in the spring, interviewing anglers. During spring and fall, surveys were conducted from mid-morning 19 Roving creel survey from Guntersville Reservoir to mid-afternoon. In the summer months, the surveys were concentrated in the early morning and later afternoon hours as very few anglers used the reservoir during the heat of the day. Except for the busy spring months, two -three hours was sufficient to interview all anglers within a study site. This schedule also permitted the crew to travel from Birmingham, survey both sites and return in a single day. RESULTS AND DISCUSSION Usage Spring fishing activity on Lake Guntersville is almost three times as heavy as in summer and fall (Fig. 1 and Table 1). Weekend usage of the reservoir is more common than on weekdays, but especially so in spring, when the number of weekend angling parties more than doubles the number fishing during weekdays. Of all anglers interviewed, approximately two-thirds were fishing from boats and one-third were fishing from the bank. Most anglers on Lake Gun¬ tersville are from North Alabama (Tables 2-4). Almost one-third (30.3%) are from the local area (<10 miles from launch site) and 76.2% are from 50 miles or less. The mean distance driven was 49.6 miles one-way. A sig¬ nificant number of anglers at Spring Creek (25.9%) come from Birmingham (Jefferson County) , which is more than 50 miles from the reservoir (Table 4). However, few Birmingham anglers appear to drive much further than Figure 1. Seasonal trends in numbers of anglers using the two study sites.

Only 1.6% of the parties at North Sauty Creek were from Jefferson County. Madison County (Huntsville) dominated the angling parties at North Sauty (52.7%, Table 4). Obviously, anglers are tending to utilize the closest available location on the reservoir. Table 2. Distances travelled by anglers to Guntersville Reservoir (one way) .

Economists typically introduce multipliers in the range of 2.5 to 7 or more (e.g., see Anderson et al., 1986). How¬ ever, they can be misinterpreted if analysts fail to state the type of multipliers and the context in which they were derived (Propst and Gavrilis, 1987). Estimates of the numbers of anglers using the two sites were obtained by extrapolating from the instantaneous counts. For example, on spring weekend days at Spring Creek, an average of 74.0 anglers were counted. Since there were 27 weekend days during the spring months of 1987, an estimated 1,998 anglers (-74.0 x 27) used the Spring Creek embayment dur¬ ing that time (Table 6). Overall, for the three-quarter sample period, 13,282 anglers are estimated to have visited one or the other of the study sites. This method assumes that the days and hours when counts were obtained were representative ones and that the number of anglers using the study sites on similar days, e.g. spring weekend, would have been simi¬ lar. The estimated totals of anglers visiting each area are underesti¬ mates because they are based solely on fishermen present at the same time the clerks were there. Fishermen leaving before the clerks arrived, or arriving after they left, of course, were not counted or allowed for by some expansion factor. Evening and night fishermen may have been con¬ siderable users of the study sites, especially in the summer. Further extrapolation can be done to provide an estimate of the total numbers of anglers using the entire reservoir during the spring, summer, and fall seasons. The two defined study areas represent 4.62% of the total surface area of the reservoir. Assuming that the number of anglers per surface acre of the study sites is representative of the whole reser¬ voir, an estimate of 13,282 x (100/4.62) - 287,489 anglers using the entire reservoir is obtained. The validity of this extrapolation to the whole reservoir may be questioned since both study areas are embayments , and if the amount of usage is different on the main reservoir (which makes up most of the surface area), the estimate will be in error. Seasonal fishing patterns do exist. In the spring, when fish are in shallow waters, there are clearly more anglers in the embayments than on the main reservoir. Thus, the total number of anglers on the reservoir would be 23 Roving creel survey from Cuntersville Reservoir Table 6.

However, the situation probably reverses in the summer when fish tend to move to deeper water. At this time of year, the anglers follow the fish and more will be found on the main reservoir than in the creeks. During these seasons, counts on the embayments tend to underestimate the total number of anglers using the entire reservoir. Thus, we believe that over all seasons, these over- and underestimates tend to balance each other. The economic information from the interviews indicated that the average angler spends $6.89 per trip in the immediate vicinity of the reservoir (within 10 miles). Thus, over the three most active fishing seasons, anglers contribute an estimated $6.89 x 287,489 - $1,980,799 to the regional economy. This is a very conservative estimate of the impact of angling on the regional economy since no "multipliers” have been ap¬ plied to the numbers. It also should be noted that this represents only money spent for nondurable goods associated with daily fishing trip expenses and does not include money spent on more expensive durable goods such as rods, reels, tackle, and boats. Most of these items are probably purchased around the angler's home town and may not represent a signifi¬ cant source of outside money flowing into the regional economy. 24 Angus and Marion Species Sought Large-mouth bass angling is the most important recreational fishery on Lake Guntersville in terms of the numbers of anglers who are actively seeking a specific species. Between 31.3 and 61.4 percent of the fisher¬ men interviewed during the three seasons were fishing for largemouth bass. Overall, 41.5% of all parties interviewed indicated they were fishing for bass (Table 7). Crappie fishermen were abundant (25.6% of parties) in the spring, but virtually disappeared from the summer and fall samples. Bream fishermen were active in the spring (17.5%) and summer (11.7%). In all seasons, less than 10% of those interviewed were seeking catfish. Roughly one -fourth of the fishermen were fishing for no particular species. Table 7. Fish sought by Guntersville anglers. Entries in the table represent the percentage of angling parties surveyed which expressed preference for each category of fish. Numbers of parties surveyed in spring, summer, and fall were 211, 128 and 44, respectively.

Catch rates remained high (over 0.7 fish/ hr) during the summer (Table 8). However, the fall surveys, conducted only during September, may not have provided an accurate representation of fall fishing conditions. This may have produced an under- estimation of the fall angling success which, presumably, increased with dropping water temperatures later in the season. Table 8. Bass angler success as average catch per hour (standard error in parentheses). Spring Summer Fall Spring Creek North Sauty Creek 0.91 (0.17) 0.87 (0.14) 0.78 (0.18) 0.71 (0.18) 0.28 0.24 (0.17) (0.07) 25 Roving creel survey from Guntersville Reservoir The abundance of bass in Lake Guntersville appears to be good as bass fishermen caught an average of 0.72 bass per hour over the study period. A national Bass Angler Sportsman Society tournament in April, 1987 pro¬ duced outstanding results (Tucker, 1987). The three-day tournament produced a record number of seven-bass limits and an average of 16 bass (12" or greater) per angler. The average catch rate, 0.60 bass per hour, is an underestimate of total bass catch rate since the top anglers caught and released many more than their seven- fish limit. In April, 1^87, 50.8% of the B.A.S.S. tournament anglers brought in limits, which is excep¬ tionally high. According to D. Kendrick, B.A.S.S. tournament director (Tucker, 1987), "Normally, if 20 to 25% of the fishermen bring in a limit, we're impressed with the lake's fishery." Similar tournament successes were repeated over the next two years at Lake Guntersville. In fact, the 1989 tournament set records for total number of bass caught, number of seven-bass limits, and total weight (Vincent, 1989). Among persons fishing for species other than bass, bream fishermen had the highest catch per hour, followed by the crappie fishermen (Table 9). Catfish fishermen experienced much lower catch rates. This was apparently compensated for by the fact that they were angling for larger fish. Table 9. Non-bass angler success. Mean catch per hour among anglers stating the particular species as their preference. Standard errors in parentheses. Crappie Bream Catfish 1.36 3.96 0.19 (0.32) (0.53) (0.09) Overall, interviews indicated that bass anglers released 62.5% of the bass they caught (all sizes included). This is encouraging, since the maintenance of a quality fishery with good numbers of fish in the larger size classes may depend on the anglers releasing more bass, especially the larger ones. Despite the relatively high catch rates, most people interviewed were somewhat dissatisfied with the result of their fishing trip. More than 85% perceived fishing as fair or poor, whereas only about 14% indicated that their success was good or excellent (Table 10). It was clear, however, that one's rating of the days' fishing success (as excellent, good, fair, or poor) often had little to do with the actual numbers of fish caught. People apparently have widely differing expectations of success from a fishing trip. Persons who caught relatively few fish would often rate the fishing as good or better than others who had been much more successful. The relationship of stated satisfaction to actual angling success is shown graphically for bass fishermen in Figure 2. 26 Angus and Marion Table 10. Quality of fishing as judged by anglers.

CHANGES IN EXTENSIBILITY AND TISSUE CHOLESTEROL OF RAT AORTAS WITH EXERCISE1 R. C. Westerfield, T. J. Pujol, and F. S. Bridges2 Department of Health Studies The University of Alabama Tuscaloosa , Alabama 35487-0312 ABSTRACT The effects of a moderate aerobic exercise program on arterial extensibility and aortic tissue cholesterol levels were determined in rats. Forty-six Lewis strain rats were randomly assigned to an exercise or non- exercise group. The exercise group was given daily aerobic exercise on a small animal treadmill for 14 weeks. Thoracic aortic segments from 202-day old subjects were excised and evaluated. Esteri- fied, unesterified, and total cholesterol were determined through chemical analysis. Tubular aortic segments were circumferentially stretched utilizing an Instron Instralab Instrument. Extensibility measure of aortic stiffness and circumferential stretch distance were determined at 15%, and 30%, of an 0.91 kg load and at the breaking point of the aortic segment. Only the breaking load was significantly higher for the exercise group. The exercise group had significantly lower levels of unesterified and total cholesterol. The findings support an inhibitory role of ex¬ ercise in cholesterol accumulation. INTRODUCTION The role exercise may play in exerting a preventive effect on the pathogenesis of atherosclerosis is ambiguous and conflicting. Several non-human studies have demonstrated, with moderate exercise, an inhibitory effect on atherogenesis (20,22,24,35). In other animal studies, exercise failed to decrease the extent and severity of atherosclerosis or prevent its occurrence (24,34,40). Evidence has been presented that moderate regular exercise alters the metabolism and absorption patterns of lipids in human and non-human subjects (12,14,38). Research has demonstrated with atherosclerosis there is a concomitant loss of arterial extensibility (10,29,30). Kramsch, et al. (22) and Leung, et al. (23) have presented evidence that one of the factors by which exercise inhibits the develop¬ ment of atherosclerosis may be the effect of exercise on arterial ectensi- bility . The present study was undertaken to determine how a moderate exercise program would affect aortic tissue cholesterol levels and arterial ex¬ tensibility in rats fed an atherogenic diet. ’Manuscript received 31 August 1989; accepted 6 November 1989. Presently at Northeast Louisiana University. 29 Westerfield, Bridges, and Pujol METHODS AND MATERIALS Sub jects Forty-six 50 day old male rats of the Lewis strain were randomly assigned to either an exercise (N-23) or non-exercise (N-23) group. Subjects were housed together in identical environmental conditions: temperature, 21.1°C, humidity 50%, and light 12 hours/day. Food and water were offered ad libitum. The subjects were fed an atherogenic diet (standard rat food pellets enriched with 2% cholesterol) for 44 days prior to the commencement of the exercise regimen and continuing until termi¬ nation of the study. The rat is known to be somewhat resistant to demonstrable atherosclerotic lesions (8,26,36). Therefore, in order to determine any effects of aerobic exercise on arterial extensibility and tissue cholesterol, an atherogenic diet was utilized to facilitate the pathogenesis of atherosclerosis. Exercise Training Non-exercise subjects remained limited to standard rat cages (20.3 cm x 25.4 cm x 45.7 cm) throughout the investigation. Exercise animals received daily (7 days/week) aerobic physical exercise on a small-animal treadmill for a 14-week duration. The exercise protocol and intensity were patterned after previous research (1,2,16,27). During weeks 1,2,3, and 4, the exercise was 0.96 km/h at 5% incline for 10 minutes; week 5 was 0.96 km/h at 10% incline for 15 minutes; weeks 6 and 7 were 1.12 km/h at 10% incline for 15 minutes; weeks 8.9, and 10 were 1.12 km/h at 10% incline for 10 minutes twice daily; week 11 was 1.28 km/h at 10% incline for 15 minutes twice daily; weeks 12, 13, and 14 were 1.28 km/h at 15% incline for 15 minutes daily. Exercise subjects received one week of training on the treadmill prior to the experimental study to ensure familiarity and proficiency. Subjects were weighed every three days to determine if exhaustion, anorexia, or weight loss occurred. There was no significant differences in body weight between the groups at commencement or termination of the study (P < .05). Pathological Procedures The subjects were 202 days old upon termination of the experiment. An intraperitoneal injection of Nembutal (.1 ml/100 gm of body weight) was used to anesthetize the subjects. A midline chest and abdominal incision was made exposing the thoracic aorta. A 31 mm tubular segment of the aorta, beginning at the innominate branch, was excised and maintained in a Lock-Ringer's solution at 37°C to reverse any spontaneous constriction. After 15 minutes, the aortic segment was stripped of its adventitia utilizing procedures described by Wolinsky and Daly (37) and utilized in previous research 3,4,6,29). A 6 mm tubular segment was excised (phrenic end) for assessment of arterial extensibility, with the remaining segment used to determine tissue cholesterol levels. Both specimens were temporarily stored in isotonic saline at 4°C. Arterial extensibility was measured by utilization of the Instron Instralab University Testing Instrument (7). The equipment and testing 30 Extensibility and tissue cholesterol of rat aortas procedure allowed visualization and strip chart recording of circumfer¬ ential stretch of arterial segments under a given load at a constant rate of elongation. The equipment and procedure were similar to techniques published by Bailey (4). Arterial segments (6 mm) were held in place to two high- tensile strength specimen hooks (.76 mm dia.) secured vertically by specimen grips. The horizontally held arterial segments were circum¬ ferentially stretched by application of a load up to 0.91 kg. Initially a circumferential stretch tension of 5% of a 0.91 kg load (45.5 g) was employed to induce lumen tautness and thus minimize error in measurement attributable to anatomical size differences in arterial segments. Circum¬ ferential stretch was induced until a force of 15% of a 0.91 kg load (136.5 g) was reached. The circumferential stretch or tension was un¬ loaded to the initial 5% point. This procedure was repeated at 30% of a 0.91 kg load (273 g) . Circumferential stretch was finally induced until the arterial segment broke or fractured. Measures of extensibility in the form of arterial stiffness and stretch distance were derived from recordings of the Instralab strip chart recorder. From the graphline generated and recorded on the Instralab strip chart recorder, the distance the arterial segment stretched under a given load could be determined in mm. In addition, from the slope of the graphline, generated from circumferential stretch tension, arterial stiffness was calculated. The slope of the arterial stretch, due to load tension, would differ according to the elastic properties of the segment being stretched under load. The arterial stiffness values (kg/cm) were calculated in the following manner: From the point where the loading line (slope line) crossed the vertical predetermined 15% and 30% load points, a line was drawn horizontally backward 5% and then drawn vertically downward until it intersected the loading line. This vertical distance was measured to the nearest 0.5 mm and divided by the predetermined and standardized recorder magnification ratio (chart speed of 12.7 cm/min. to crosshead speed of 0.127 cm/min). This quotient was finally divided by 0.0455 kg (5% of 0.91 kg load) to derive the stiffness value (kg/cm). Breaking load was the tension in kg necessary to break or fracture the arterial segment. Stretch distance was derived by calculating the distance (nearest 0.08 cm) from the initial 5% load t the 15%, 30%, and breaking point. Cholesterol Assay Methods The technique for cholesterol extraction was adopted from methods utilized by Folch (11). For chemical analysis of tissue cholesterol, arterial segments were homogenized and extracted with methylene chloride- methanol (2:1). The methylene chloride -methanol was washed with 0.2 (0.2x40) volumes of saline. The aqueous phase was separated by centri¬ fugation, removed, and washed with 40 volumes of methylene chloride - methanol-saline (86:14:1). The methylene chloride-methanol phases were pooled and evaporated to dryness under nitrogen at 40°C. Samples were divided into two equal fractions from analysis of free and esterified cholesterol. The fractions analyzed for cholesterol esters were treated with cholesterol esterase and analyzed for free cholesterol. The amount of cholesterol in the untreated fraction was subtracted from the treated 31 Westerfield, Bridges, and Pujol fraction to give the amount of esterified cholesterol present. Choles¬ terol was isolated from other lipids by three-dimensional thin layer chromatography. Cholesterol was visualized by standing the plates in an iodine -vapor chamber at room temperature for one hour. The amount of cholesterol was determined by calorimetric analysis using the Dow method (32). Measurements were made in a Beckman spectrophotometer at 565 nm and reported as milligrams of cholesterol per gram of aortic tissue. Statistical Analysis Data from extensibility measures and chemical analysis for cholesterol were statistically treated through multivariate analysis of variance (17) . Hotellings multivariate test of significance was significant (P<.001). Univariate F-tests were used to determine significant difference between the two groups . RESULTS The aortic breaking load value was the only extensibility determi¬ nation which was significantly different between the exercise and non¬ exercise groups (Table 1) . Mean aortic breaking load for exercise group (0.563 + 0.025) was significantly greater than the non-significantly different between the two groups. Measurements of circumferential stretch distance of the two groups at 15%, 30%, and breaking point also were significantly different. Significant mean differences between the exercise and non-exercise groups in aortic tissue cholesterol (mg of cholesterol per gm of aortic tissue) was demonstrated (Table 1). The non-exercise group had a sig¬ nificantly higher unesterified cholesterol level (0.215 + 0.003) than did the exercise group (0.173 + 0.002) and a significantly higher total cholesterol level (0.852 + 0.002) than the exercise group (0.817 ± 0.002). There was no significant difference between the exercise and non-exercise groups with regard to esterified cholesterol (0.644 + 0.003 vs. 0.637 + 0.002, respectively). DISCUSSION The results of this study partially support previous research in demonstrating exercise as a preventive measure in the pathogenesis of atherosclerosis (22,24). The findings of significantly higher levels of unesterified and total cholesterol in the non-exercise, and higher breaking load for the exercise group, support the preventive actions of moderate exercise. The study failed to detect significant differences between the exercise and non-exercise groups in arterial extensibility measures of stiffness at 15% load, 30% load, all stretch distances, and in esterified cholesterol tissue levels. Studies by Newman et al. (29), and Pynadath and Mukherjee (30), have demonstrated a decrease in arterial extensibility with increasing athero¬ sclerosis, and the loss of arterial elasticity being proportional to atherosclerotic involvement.

Westerfield, Bridges, and Pujol significant differences between the exercise and non-exercise groups in extensibility at 15% and 30% load was in conflict with these previous studies. The detection of a significant difference in arterial tissue lipids would appear to indicate physiological if not pathological changes had occurred. Perhaps the extent of atherosclerotic development was not sufficient to elicit subtle changes in arterial extensibility. The rat model has been shown to be appropriate for atherosclerosis research but is known to be more resistant to diet induced atherosclerosis than other animal models (8,26,36). Hasler (20,21) utilizing an atherogenic diet consisting of 10% lard and 4% cholesterol was able to produce only moderate atherosclerotic changes in the intimal surface of rat aortas. In addition, the researcher found minimal differences between exercise and sedentary rats in intimal surface plaques. In the current investigation the resistant nature of the subjects, coupled with the experimental time frame, 14 weeks, may have prevented sufficient changes in the intimal layer necessary for detection of extensibility variations. The finding of a significant difference between the groups with regard to breaking load would be in agreement with previous studies. With ex¬ treme or high levels of artery stretch, the medial layer becomes signifi¬ cantly involved. The ratio of elastin to collagen tissue in the medial layer is an important factor in elasticity demonstrated at high levels. Ruderman et al. (31) and Wong et al. (39) have provided evidence that exercise can and does lower the collagen to elastin ratio thus preventing a loss of elastic characteristics. The demonstrated higher levels of unesterified and total cholesterol in the non-exercise subjects would appear to indicate an acceleration of lipid deposition in arterial tissue. Numerous studies have shown exercise to lower serum lipid levels in humans and non-humans (5,9,14,18). The measurement of arterial tissue lipids has not been as extensive as serum. Forsythe et al. (12) found exercise lowered the total heart lipid levels in pigs. Gollnick (15), Fukida et al. (13), and Naratan et al. (28) determined that exercised animals had significantly lower liver lipids than sedentary controls. The failure of exercise to significantly reduce esterified cholesterol was surprising since unesterified and total cholesterol levels were re¬ duced. Atherosclerotic lesions demonstrated a higher relationship to esterified cholesterol than unesterified or total levels. The conversion of lipids to the esterified form has been shown to be partially attribu¬ table to the level of unesterified cholesterol, which in turn is partially related to serum lipid levels. The significantly lower levels of un¬ esterified and total cholesterol in the exercise group would be consistent with the lowering of serum lipids through exercise. Previous researchers (19) found cholesterol esterification in the atherosclerosis resistant rat was higher than in other more susceptible animals. These researchers as well as Small and Shipley (33) postulate that esterification may be a protective mechanism in converting toxic atherogenic free cholesterol to a less toxic esterified form. Perhaps exercise initially stimulates the protective mechanism which converts unesterified to esterified, but long¬ term effects would be the reduction of esterified through limiting the 34 Extensibility and tissue cholesterol of rat aortas unesterified available for conversion. Other plausible explanations include physiological, enzymatic, and chemical changes in the arterial wall due to exercise. LITERATURE CITED 1. Ahrens, R.A. , C.L. Bishop, and C.D. Berdanier.

Dusi Department of Zoology and Wildlife Science Alabama Agricultural Experiment Station Auburn University , AL 36849 A female black bear, Ursus americanus , was killed by a truck, 29 November 1979, near Turnerville, Mobile Co., Alabama. The bear weighed about 150 lb (68 kg), and measured 420 cm total length, 65 mm tail length, 180 mm hind foot, and 105 mm ear length. A longitudinal section of an upper first premolar showed the following pattern of annuli in the cementum (Fig. 1). Regardless of the method of assigning age to annuli, there is no doubt that it is an older bear. On examining the cleaned skull it was discovered that there was a stone wedged between lower molars 2 and 3 in the right dentary bone (Fig. 2A, B, C) . The stone had caused the teeth to separate and the dentary to erode around them, exposing the roots of the teeth (Fig. 2A, E) . The stone also caused the bear to chew with its left molars, causing them to wear much more than the right molars (Fig. 2A, D) . Figure 2D also shows the normal, uneroded dentary by the molars of the left mandible. The bear obviously lived with the discomfort of the stone for a number of years. Figure 1.

THE BLACK BEAR IN SOUTHWESTERN ALABAMA1 Julian L. Dusi and D. Tommy King Department of Zoology and Wildlife Science and Alabama Agricultural Experiment Station Auburn University , AL 36849 ABSTRACT This was the first ecological study of the black bear, Ursus americanus , in Alabama. The study was conducted near Saraland (Mobile County), where the greatest bear population density occurs. Our study area (103.6 km2) contained a population of at least 10 bears that utilized about 60 km2. Five bears, ranging from 2 to 8 years of age, were trapped, measured, and radio- tagged. Annual home ranges of 4 bears ranged from 4.5 - 42 km2, with a mean of 25.9 km2. Winter home ranges of these same bears ranged from 0.5 - 1.5 km2, with a mean of 0.93 km2. Greatest activity occurred between May and December. Winter activity was greatly re¬ stricted. During the winter, radio -tagged bears were alert and moved when we tried to home in on them. Of the baits used in trapping, shelled corn and honey was the best combination. Bears did not respond to scent or bait posts. Habitats used were upland mixed pines and deciduous trees, with oaks ( Quercus sp .) and other mast trees, adjacent to swamps with very dense cover of- titi ( Cyrilla racemiflora and Cliftonia monophylla) . Acorns, berries, and other fruits provided most food items. The bears tolerate people living on the edge of the area. They were not affected by the gas wells and drilling crew activity scattered through the area. INTRODUCTION The black bear was originally distributed in suitable habitat throughout Alabama and the Eastern United States (Hall 1981) . Howell (1921) stated that the black bear occurred only in the lower tier of counties in Alabama. Prior to Howell's work, a large portion of Alabama had been deforested and cotton and other agricultural crops occupied the land that was not mountainous or swampy (Lineback 1973) . In 1924 the black bear was listed as a game mammal with an open hunting season. In 1940, however, the State Department of Conservation closed the black bear season, as it remains today (Gary Moody pers. commun. ) . The Rare and Endangered Vertebrates of Alabama Symposium (Anon. 1972) , listed the black bear as "rare." In 1976, both subspecies of the black bear (Ursus a. americanus and Ursus a. floridanus ) were listed as "endan¬ gered," and the number of Alabama black bears was estimated to be about 150 (Boschung 1976). In 1983 the first Alabama nongame wildlife con¬ ference was held at Auburn University (Anon. 1984, Mount 1986) in which a group of specialists grouped the vertebrate species of the state into the categories: endangered, threatened, special concern, and poorly known. The black bear was reclassified in the "special concern" category. ’Manuscript received 6 December 1989; accepted 18 January 1990. 41 Dusi and King The objectives of this study were to assess the ecology of the black bear in southwestern Alabama and to formulate management recommendations. METHODS The main study area was located in Hells' Creek Swamp northwest of Saraland, Mobile County, Alabama. It was bounded on the south and west by Celeste Road, on the north by Salco Road, and on the east by Interstate Highway 65, U. S. Highway 43, and by the Burlington Northern Railway. Radcliff Road subdivided the area into northern and southern halves. The Mobile Water Canal extended from southwest to northeast. This canal was about 10 -m wide and was flanked on both sides by roads, one of which was surfaced with oystershell and the other unimproved. The total width of the water canal clearing was about 100 m. On either side of the water canal was swampy land covered with tupelo ( Nyssa aquaCica ) and titi. The land gradually increased in elevation providing upland, mixed forest habitat in the western part of the study area. A number of gas wells was present, mostly along the water canal, and access roads connected them. Houses were located along parts of Celeste and Radcliff roads. Hunting rights of the study area were owned by several hunting clubs. This restricted our free use of the area during the deer and turkey seasons, which were from early November to January 31 and from March 1 to April 30. We carried out a trapping program from early May until November of each year, utilizing culvert traps and Aldrich snares (Dusi and King 1987). The snares were set in cubbys made of old, discarded, corrugated sheet iron (Fig. 1) which was present on the area and was familiar to the bears. Traps were baited with 1 qt each of shelled corn and honey. Several baits were tested at the traps and at scent posts (shelled corn and honey, sardines, meat scraps, and burned bacon, Fig. 2). Opossums ( Didelphis virginiana) and raccoons ( Procyon loCor ) were so abundant that control using small live traps near our bear sets was necessary to keep them from raiding the bear traps. Trapped bears were anesthetized with ketamine hydrochloride and xylazine, using a dart gun. The sedated bears were then radio tagged with Wildlife Materials, Inc. HLPM-22200-LD transmitters, ear tagged with National Band 6t Tag Co. #49 self -piercing tags, and measured (total length, tail length, hind foot length, ear length, canine length, chest girth, and weight). The first upper premolar tooth was removed for ageing, the bears were released, and their positions were monitored with a Wildlife Materials, Inc. TRX-24 receiver and a 3-element Yagi antenna, once or twice a day, for the rest of the study. Habitat data were obtained using transects (Lome Malo , pers . commun. ) . It soon became evident that the key vegetation was the thick, impenetrable cover in the swamps, which could not be sampled by our transect methods, because we would have to destroy the understory vegetation to enter the swamp. Food habits were determined from the analysis of bear scats for seeds and animal remains (Lome Malo, pers. commun . ) . 42 The black bear in Alabama Fig. 1. Trap cubby using an Aldrich snare. RESULTS AMD DISCUSSION A total of 5 bears was trapped over a period of 611 trap nights (an average of 122 trap nights per bear). One large bear, whose size was estimated from his large footprints, broke a snare and escaped. During the study one unmarked female bear was killed in an automobile accident on Celeste Road. A female and 2 cubs were seen on the area. This is a total of at least 10 bears, that we could account for, using about 60 km2 of the 103.6 kmz study area, or about 1 bear per 6.5 km2. Felton and Markam (1977), from 1972 - 1974, had a density of bears in their Tennessee study area of 1 bear per 2.71 km2. The Tennessee density is over twice the density of our population, which we believe to be the most dense popula¬ tion for Alabama. The age distribution of the population of Hells' Creek Swamp varied from 2 yr for the 15.4-kg female and 24.5-kg male, to 6 yr for the 55.7- kg female and 8 yr for the 70. 3 -kg female. The ages and weights of the female with cubs and the large bear that escaped the snare can only be 43 Dusi and King estimated. Several years prior to the study there was a Celeste Road male bear kill that was 193.2 kg and 17 yr old. Population movements and home ranges varied seasonally. Winter (Janu¬ ary - March) home ranges were small, ranging from 0.26 km2 to 1.04 km2 (Fig. 3, Table 1). Annual home ranges varied from 2.3 km2 to 20.7 km2 (Fig. 4, Table 1). The young male, B-2, had the largest annual home range. The female, B-3, had an annual home range that was almost iden¬ tical with that of B-2. These data suggest that he may have been her offspring. His home range may also reflect his sex and the generalization that males have larger home ranges than females. The 2 -year-old female had the smallest home range. The food habits for some of this population were, in part, determined from the crude analysis of 22 scats and 1 stomach sample (fall-6, winter- Bacon burner at scent post.

He found that acorns (Quercus spp . ) were the principal foods of fall and winter and that they were supplemented in the fall by black gum ( Nyssa sylvatica) , blue¬ berries (Vaccinium sp .) , beetles, and other invertebrates. In the spring corn (Ruhus sp.) and plums ( Primus sp.) were supplemented by beetles. In the summer, corn was the only grain recovered in the 2 samples. This com could have been from our trap bait. Acorns were abundant during the fall and winter seasons of this study. Oak trees were adjacent to the swamps and acorns were easily accessible. Except for several small food plots, no planted corn was available. Our traps were heavily baited and were often raided by bears without making a catch. Therefore, com was readily available during the spring and summer when we could trap. This corre¬ sponds with the seasons when com was found in the scats , When we designed our study we tried to find an area with a bear population that was representative of the low density populations of the state but with enough bears to get movement data, etc. As it turned out, we probably located the most dense population in the state. This was a fortunate mistake because we were able to get an amount of data which would otherwise have been missed. While we carried out our study, we became involved in several bear damage cases. We spent about 68 trap nights on the farm of James Daly,, north of Grand. Bay, which is southwest of Mobile and in Mobile County . Here a female bear and her cub occupied an area estimated to be between 40 and 50 ha. The bear had raided Daly's bam and eaten shelled corn that he had stored for livestock feed. It also had chewed and scratched 268 trees and dug holes in his lawn and adjacent fields. We attempted to capture the female bear in culvert traps and snares but only succeeded in capturing his dog or livestock. This was the only site we visited where a bear scratched so many trees and dug so many holes. We visited several other sites where bears were reported to be causing problems and in no cases were we able to trap the problem bears. They appeared to be much more wary than the bears on our study site. During the period of the study, a bear was hit by an automobile near Decatur, Limestone County. This bear was taken to the Jimmy Morgan Zoo 47 Dusi and King Rescue Unit, in Birmingham, and wa& treated and later released by us in Clarke County, where it has since been seen several times. This bear had been tagged by the Georgia Department of Natural Resources and had been relocated once before it came to Alabama. Another bear was active in the Birmingham area, where it dug in a yard and scratched on an adjacent mobile home. A third bear appeared for several days near Eufaula, Barbour County. A fourth bear appeared at Fairhope , Baldwin County for several days. Another bear was shot by a landowner near Cedar Bluff, Cherokee County. Still another was reported at the eastern side of Bankhead National Forest, in Cullman County. Another bear has been reported near the Tuskegee Airport, Macon County, and still another near Spring Villa, Lee County. All these reports indicate quite a change from 20 years ago when we rarely heard of a bear, except in the Mobile area. With the growth in the human population and the increases in forested lands, bears are noticed more and perhaps increasing in numbers. There¬ fore, more study is needed on these isolated individuals and their habitat requirements. We also need to develop proper handling of garbage and other attractants which may lure bears near houses. Finally, we need a good education program so that the people of Alabama know what to expect from bears and learn to exist harmoniously with them. ACKNOWLEDGEMENTS Many people helped us in this project. We especially want to thank Conservation Officer James Harbin and his son Bruce, Fred Kellum, District Biologist Eugene Widder, John Cutts, Raymond Keyser and Charles Radcliff.

SYLACAUGA METEORITE FALL1 Harold Povenmire 215 Osage Dr. Indian Harbour Bch. , FL 32937 ABSTRACT This paper summarizes the available data concerning the first well- documented" injury to a human being by a meteorite fall. Precise co¬ ordinates of the primary mass have been determined. A determination of its radiant and its orbital parameters have been made. Several candidates for related meteorite falls and an asteroidal parent body have been suggested based upon solar longitude, approximate radiant, and petrologic classification. Suggested strewnfield parameters are indicated, since more unrecovered fragments probably survived impact. Sylacauga , Alabama Revisited On November 30, 1954, the first well-authenticated case of a meteorite striking a human being occurred. It was written up briefly in a report by the geologists who were on the scene (Swindel and Jones, 1954). The meteorite itself has been described separately (Mason, 1963) . The purpose of this report is to record many of the details that were not recorded previously before they are historically lost, as most of the persons involved are now deceased. The site of the meteorite fall was in the southwest corner of an approximately 136 year old farm house located on Odens Mill Road. The house is located just south of the old Birmingham highway (Rt. 91) in the town of Oak Grove, northwest of Sylacauga in Talladega County, Alabama. The postal address is Rt. 7, Box 726 B, Sylacauga, Alabama, 35150. The house was owned by Mrs. Birdie Guy until her death in 1988. The precise coordinates of the impact of the primary mass were: longitude 86°17' 40". 2 W, latitude 33°ll'18".l N as scaled from the U. S. Geological Survey 7. '5 Sylacauga West, Alabama, 1980 topographic map. The elevation of this site is 180 meters. On December 1, 1954, a farmer, Julius Kempis McKinney, recovered the second and smaller fragment. The approximate impact coordinates of this object were scaled as longitude 86°17'20".7 W, latitude 33°13'08".4 N at an elevation of 161 meters. The distance between these impact points is 3750 meters. It was found southwest of the railroad tracks and across from the road connecting Odena and Lipsy (formerly called Zubers) . Mr. J. K. McKinney was hauling a load of firewood along a woods trail in a wagon pulled by two mules. One of the mules shied away from an object, apparently because of its odor. (Has any meteorite hunter ever ’Manuscript received 8 May 1989; accepted 9 February 1990. 50 Povenmire considered using bloodhounds to help search for freshly fallen meteor¬ ites?) Mr. McKinney thought it must be a snake but instead found only a black rock. He threw it down, but later retrieved it, and kept it until December 8, 1954. It was then reported and given to geologists to examine (Swindel and Jones, 1954). He later sold the meteorite for a "handsome sum" which allowed him to purchase an automobile and a 10 acre farm. In falls of stony chondritic meteorites, especially large ones where fragments show highly angular plane surfaces and thin fusion crusts, several fragments are usually found. At least three distinct fragments were reported to have been visible after the terminal burst and at least three very loud sonic booms were heard and felt. If more fragments survived to impact, they should be found along the same azimuth as the line from the Hodges fragment to the McKinney fragment. The rolling terrain between the impact sites is partly farm land and partly resi¬ dential neighborhoods with a fairly high population density. This researcher believes that if people in the area were made aware of the possibilities, the chances of recovering additional fragments are reasonably high. The strewfield containing such fragments should be an ellipse with the long axis in a north-south direction centered at longitude 86°17'30."0 W. It should have a minor axis diameter of at least 3.0 km. The southern end should be at 33°09' N and extend north to 33°20'N. This is a large area but the observations support these parameters. It is interesting to note that many persons from Montgomery to Sylacauga reported that they experienced television interference at the time the meteorite fell (Birmingham News, 1954, December 1). This phenomenon has been noted on other fireball reports analyzed by the Florida Fireball Patrol. On this Tuesday afternoon, Mrs. Ann Elizabeth Hodges, 34, was not feeling well and took a nap after lunch. She was sleeping on her right side on a couch in her front room. Apparently the sonic boom and the meteorite impact occurred almost simultaneously. She was stunned by the noise of the impact and did not at first realize that she had been hit by the ricocheting meteorite. She and her mother, Mrs. Ida Franklin, who was sewing in the adjacent room, at first believed that the gas heater had exploded. A large bruised knot quickly appeared on Mrs. Hodges hand. It was only when sunlight was noticed coming through the square (0.35 meter on a side) hole in the corner of the ceiling was the meteorite found (Fig. 1) . Its black surface appeared sooty, but the black color did not rub off. It had a slightly sulfurous odor and was very warm to the touch. Mrs. Hodges reportedly saw a boiling dust column over her house shortly after the impact. Mrs. Hodges called the police. The Chief of Police, W. D. Ashcraft, took Mrs. Hodges to a doctor, Moody D. Jacobs, and with her permission, kept the meteorite. She was thoroughly examined and x-rayed by the doctor and released even though her left hand, left hip, and abdomen were sore and swollen (Jacobs, 1988). 51 Sylacauga meteorite fall Figure 1. Mrs. Hewlett Hodges holding the 3.68 kg meteorite that hit her after penetrating the roof and ceiling of the house. The next night she was admitted to Sylacauga General Hospital for five days of rest as "the excitement was too much for her to sleep and to shield her from the endless string of visitors and telephone calls." It was reported that there were traffic jams in the area for several miles. There were also approximately 200 reporters trying to interview Mrs. Hodges . 52 Povenmire Mrs. Hodges was not seriously injured and no bones were broken. The next day, a 10 x 20 cm bruise appeared on her hip and abdomen showing the imprint of the meteorite even though she was covered by two heavy quilts (Life Magazine, 1954). She believed that these saved her from serious injury. Mrs. Hodges required several hours of daily bedrest and suffered severe pain for many weeks. While her physical health returned to normal after several months, she never completely recovered her emotional and mental health. Mrs. Hodges, who was by nature quiet and shy did not even want to look at the meteorite when it was returned to her. Both Mr. and Mrs. Hodges remarked that the meteorite had caused a lot of pain, suf¬ fering and expense, and stated many times that they wished that the event had not involved them (Birmingham News, 1979). The notoriety and publicity of the event did not bring them happiness and was a contributing factor to their divorce in 1964. Mrs. Hodges' health declined further after that and she died of a stroke in a Sylacauga nursing home in 1972. She is buried in the Baptist Charity Cemetary at Hazel Green, Alabama with a very small, undistinguished headstone (Sims, 1988). On one corner of the meteorite, the fusion crust is broken showing the grey interior (Fig. 2). This broken end made first contact with the roof and small amounts of the roofing tar are embedded in the meteorite at this point. An examination of the roof, walls, and radio that were struck first appears to indicate that the meteorite's kinetic energy had essen¬ tially been damped to zero when it struck Mrs. Hodges. The last object the meteorite contacted before it hit Mrs. Hodges was a large Philco console radio. The radio chassis was made of tough, curved, laminated plywood. The meteorite broke a hole approximately 8 x 8 cm in it. This radio has been preserved by Eugene Hodges. Prior to penetrating the roof, the meteorite had a calculated velocity of approximately 270 km per hour (Halliday, Blackwell and Griffin, 1978). A direct hit would have almost certainly been fatal. The Hodges fragment of the meteorite was taken by helicoper to Maxwell A.F.B. Montgomery, Alabama. It was then flown to the Air Force Technical Intelligence Center at Wright - Patterson A.F.B. , Dayton, Ohio for identi¬ fication and analysis. In the United States, three separate appellate court decisions (Oregon, Iowa, and New York) state clearly that a meteorite belongs to the owner of the land on which the impact occurred. The Hodges were renting the property on which the house stands, so legal possession of the meteorite defaulted to the landowner, Mrs. Birdie Guy. Mrs. Guy gave up all rights of possession of the meteorite on September 22, 1955. Mrs. Hodges immediately received offers of over $5500 for the object. Mrs. Hodges later becme the sole owner and kept it for 15 months until March, 1956. Mrs. hedges donated it (for remuneration) to the Alabama Museum of Natural History, then a branch of the Geological Survey of Alabama. The Hodges fragment had a mass of 3.68 kg and a specific gravity of 3.70 and is on permanent display at the University of Alabama-State Museum of Natural History at Tuscaloosa, Alabama. 53 Sylacauga meteorite fall Figure 2. The Sylacauga 3.68 kg primary mass showing the typical highly angular flat sides. The McKinney fragment, (1.68 kg) is pyramidal is shape with a flat top. Its basic dimensions are 10 x 10 x 12.5 cm. It is on display at the National Museum (The Smithsonian) in Washington, D.C. The time of the fall has been frequently (but incorrectly) published as 1:00 p.m., C.S.T. (Graham, Bevan and Hutchison, 1985). The fireball was widely sighted and timed at or slightly before 12:45 p.m. (+/- 1.0 minute), C.S.T. The calculated duration for the dark portion of the flight was approximately 130 seconds (Halliday, Blackwell and Griffin, 1978) . Because of many small timing uncertainties the adopted time for this object's impact is 12:46 p.m., C.S.T. (18:46.0 U.T.) (Lovelass, 1988). The sidereal time of the impact of the primary mass is 17:36:15 (Dunham, 1987). The corresponding Julian date is 2435077.2819 (Sims, 1988). The meteorite is an olivine bronzite chondrite (H4) . It is a rough parallelepiped with dimensions of 17.7 x 11.8 x 11.0 cm. Low-angle lighting shows one side is smoother than the other and exhibits atmos¬ pheric ablative orientation. The black fusion crust is less than 1.0 mm 54 Povenmire thick. The interior resembles grey concrete. An approximately 31 mm diameter core has been removed from the bottom of this object (34 mm deep) for internal examination and thin section analysis (King 1987). This researcher examined the primary mass and counted as many as 15 flat surfaces where fragments may have broken off. Most of these were probably consumed in the ablation process as evidenced by the many small sparks , long dust train, and mushroom- shaped terminal burst. Most observers described the massive train and terminal burst cloud as white. Some observers, who were looking nearly into the Sun and saw the dense cloud by silhouette, described it as dark or black (Swindel and Jones, 1954). The cloud lasted at least 15 minutes and trailed off in a spiral. The sky was very clear and the terminal burst and start of the dark flight portion of the fall was clearly visible from the R.O.T.C. field at the University of Alabama at Tuscaloosa (Swindel and Jones, 1954). Donald Lovelass, a student, was facing east and saw the descent of the fireball. The fireball appeared to be light orange in color and had very slow apparent motion in its several seconds of visibility. Its apparent diameter at this distance was much less than the full moon and reminded him of a ball from a roman candle at "some distance" (Lovelass, 1988). This observation site was approximately 116 km to the WNW of the Hodges' house and would indicate that the terminal burst occurred at an altitude of approximately 19 km. The loud sonic phenomena heard in the Sylacauga area and to the SSW support this (Swindel and Jones, 1954). The sonic phenomena were heard and felt so strongly in Montgomery, some 75 km to the SSW that a boy was nearly knocked off a bicycle (Time, 1954). A line connecting the impact points indicate a trajectory azimuth of approximately 9.5° east of north. The winds at this time were from the south-west as indicated by the conspicuous dust train and terminal burst cloud (Swindel and Jones, 1954). Since lighter fragments are affected by the winds more than heavier ones, the flight azimuth adopted for computa¬ tional purposes is 0°. The radiant was high in the SSW sky as indicated by the observed azimuth, nearly vertical train column, and the intense sonic phenomena. The massive terminal burst was observed essentially at the zenith over Sylacauga. This would place the radiant in or near the constellation of Ophiuchus . This is very near the southernmost declination of the ecliptic. The exact position of the Sun at the time of the meteorite impact was Right Ascension 246. °12, Declination - 21.°37 (Equinox 1950.0) (Kronk, 1987). The meteorite's position is east of the position of the Sun at the time of impact, so an observer at Sylacauga would see the meteorite apparently coming almost directly out of the Sun. This meteorite crossed the Earth's orbit at Solar Longitude 247° 42 '58. "9 (Equinox 1950.0) (Dunham, 1987). Since the meteorite came in on the sunward side of the Earth, it had passed perihelion and was traveling outward from the Sun. Since it probably passed perihelion when it was north of the celestial equator, it would have crossed the Earth's orbit at its descending node. 55 Sylacauga meteorite fall All chondritic meteorites fragment during their entry into the Earth's atmosphere. The aerodynamic stresses on these meteorites are greater than their tensile strength. At the latitude of Sylacauga, 33° N, the Sun was approximately 44° above the southern horizon at the time of impact. The observed path of the meteor indicated a radiant with a higher altitude. After much study of the observers' descriptions of the path, and the impact locations, the following radiant was computed using both the graphical and mathematical methods of Olivier (Olivier, 1925). Date November 30, 1954 Time 18:46.0 U.T. R. A. 261. °0 Dec . + 5 ,°0 (1950.0) An attempt was made to determine a general shape of the orbit and a range of approximate orbital elements. Even with the many approximations, the orbit is surprisingly consistent and is close enough for comparison purposes to link other known or related objects. A literature search was made for the orbital elements of Apollo asteroids, fireballs, meteorite falls, earth crossing comets, and radar meteor orbits. When this orbit was compared with the known Apollo asteroids it became obvious that (1685) Toro was a much more likely candidate than any other known asteroid. Visual meteor showers cannot be compared with this event because their radiants would be too near the Sun and therefore in daylight. Two radar meteor orbits are being examined. Comets that make close approaches (< .1 A.U.) to the earth's orbit have been examined but no likely candidates have been found (Lovell, 1954). The best candidates for related meteorite falls on the basis of a combination of solar longitude, radiant altitude, and petrological classification are as follows: NAME OF FALL DATE LOCAL TIME LONGITUDE TYPE Kerilis, France Nov. 26, 1874 10:30 3° 18 'W H5 Kutais, USSR Nov. 28, 1977 08:00 39° 18 ' E H5 Xingyang, China Dec . 1. 1977 18:57 114° 19 ' E H5 Farmville, N.C.

It is the opinion of this researcher that none of the numerous reports that were received in the local press in the fol¬ lowing weeks had any connection with this event since the radiant of this meteorite fall was below the horizon in those locations at their reported times . 56 Povenmire BIBLIOGRAPHY Advance, 1954 Sylacauga, December 2.

A RANGE EXTENSION OF THE OLIGOCHAETE PIQUETIELLA MICHIGANENSIS' C. Rex Bingham and Andrew C. Miller Environmental Laboratory U.S. Army Engineer Waterways Experiment Station Vicksburg , Mississippi 39180-6199 ABSTRACT The oligochaete Piquetiella michiganens is (Annelida: Oligochaeta: Naididae) was found in pool/riffle habitat in Luxapalila Creek, a tributary of the Tombigbee River near the Mississippi-Alabama border. This species, reported from the Great Lakes and upper Mississippi River, has previously been collected only as far south as Virginia. Piquetiella michiganens is (Annelida: Oligochaeta: Naididae) was collected from a gravel riffle and adjacent pool of Luxapalila Creek, a tributary of the Tombigbee River near the Mississippi-Alabama border. This species has been reported in north-central North America as far south as Virginia (Brinkhurst 1986). It has been collected in the Great Lakes and upper Mississippi River east to the Susquehanna and Chemung rivers in New York (Hiltunen and Klemm 1980, Klemm 1985), and south to the Wabash River in southern Indiana (Dr. Michael S. Loden, personal communication). In June 1988, 20 specimens were found in four of five samples taken with a 10-cm diameter corer (Miller and Bingham 1987) at a gravel riffle in the upper reach of the creek at Millport, Alabama. Densities (+SD) were estimated at 314.3 + 258.2 individuals/m2. In a nearby pool two of five core samples yielded one specimen each with an estimated density of 31.4 + 38.5 individuals/m2. Similar sampling at two pools and two riffles in the lower river near its confluence with the Tombigbee River yielded no P. michiganens is . However, in the fall of 1988, a single P. michiganens is was collected in a riffle in the upper section of the lower reach. Luxapalila Creek is characterized by moderate to high water ve¬ locities, sediment-free gravel, and well -oxygenated water. Physical conditions are similar throughout the river; however, pools are more extensive in the lower reach. More complete macroinvertebrate surveys in the central United States would establish whether the apparent disjunct distribution of this species is the result of incomplete data or specific habitat requirements that are occasionally met at the periphery of its range . ’Manuscript received 23 December 1989; accepted 13 January 1990 60 Bingham and Miller ACKNOWLEDGEMENTS This study was funded by the US Army Engineer District, Mobile (Mobile, Alabama).

SYMPOSIUM ON THE STATUS OF ENDANGERED SPECIES IN ALABAMA Richard F. Modlin, Organizer and Moderator Department of Biological Sciences The University of Alabama in Huntsville Huntsville , AL 35899 INTRODUCTION A goal during my chairmanship (1987-89) of the Biological Sciences Section of the Alabama Academy of Science was to organize and present a symposium on the endangered and threatened species in Alabama. This goal was reached and the symposium materialized at Birmingham- Southern College on 24 March 1989 as part of the annual meeting of the AAS . It was pre¬ sented to a large concerned audience. This was the fourth such symposium to be held in Alabama. The first was held in 1972 at Birmingham- Southern College (Keeler 1972) , the second in 1974 at the University of Alabama (Boschung 1976), and the third at Auburn University (Mount 1984, 1986). The objectives in each were to identify and provide information on those species on the edge of, and those threatened toward, extinction. The objectives of the fourth symposium were to update, add to, and crystalize this past body of information in hopes of stimulating an awareness of the problems facing our state's wildlife resources and to provide direction for future research. The symposium treated plants, animals, and habitats. Five speakers from the Alabama community of field biologists, all experts in their field, were asked to make presentations. Dr. Steven C. Harris from the Geological Survey of Alabama presented information on the invertebrates . Fishes were treated by Dr. J. Malcolm Pierson of the Alabama Power Compa¬ ny. Auburn University provided two eminent scientists to the symposium. Dr. Robert H. Mount discussed the status of the state's reptiles and amphibians and Dr. George W. Folkerts talked on endangered and sensitive habitats in our state. Dr. Dan C. Holliman from Birmingham- Southern College informed the audience of the problems facing the birds and mammals of Alabama. Each of these presentation stimulated the audience and generated numerous questions and considerable discussion. I would like to thank each of the presentors for their contributions which lead to the success of this symposium. Four publications were generated as a result of the symposium and are published in this issue. The articles summarize the information on the invertebrates, fishes, amphibians and reptiles, and birds and mammals presented during the symposium. Future symposia on Alabama's threatened and endangered species, and species of concern, are presently being planned. In the immediate future, it is hoped that, the symposia will direct their discussions toward spe¬ cific problems, such as particular animal or plant taxa or habitats that may require special attention and/or examination. Alabama is a special 62 Modi in state with a tremendous diversity of animals, plants, and habitats. Many of these are unique or extremely fragile and are constantly threatened by extinction. Consequently, there is a definite need to continually moni¬ tor, and be aware of problems in, our natural resources and bring this information to the scientific community, governmental officials, and the public. I would like to acknowledge the committee that helped organize the fourth Symposium on the Status of the Endangered Species of Alabama. This committee consisted of Dr. Dan Holliman of Birmingham- Southern College; Dr. Robert Stiles, Samford University; Dr. Ken Marion, UAB; and Dr. Tom Jandebeur, Athens State College. Without their help this symposium would not have left the launch pad. I would also like to thank Dr. William Mason, Editor of the Journal of the Alabama Academy of Science, for providing an avenue for the dissemination of our information and the anonymous reviewers that helped refine the articles that were submitted for publication. Support for this symposium was provided by the Alabama Academy of Science and Birmingham- Southern College. LITERATURE CITED Bos chung, H. 1976.

PRELIMINARY CONSIDERATIONS ON RARE AND ENDANGERED INVERTEBRATES IN ALABAMA1 Steven C. Harris Biological Resources Division Geological Survey of Alabama Tuscaloosa , AL 35A86 INTRODUCTION The first symposium on threatened and endangered species of Alabama was organized in 1972. This symposium only considered vertebrates, but in 1976, at the second symposium, the format was expanded to include plants and selected invertebrates, as well as vertebrates. Also at this second symposium, the categories of endangered, threatened, and special concern species were precisely defined and utilized in a resulting publication (Boschung, 1976). However there was no accompanying legislation by the state of Alabama to give legal status to those species in need of pro¬ tection. Only those few species in Alabama considered to be threatened or endangered under the U.S. Department of Interior, Endangered Species Act of 1973 are officially protected. In 1982, the fauna of Alabama received renewed attention with the creation of a Nongame Wildlife Program by the state legislature. The first conference on nongame wildlife in Alabama was organized in 1983 with two resultant publications, "Vertebrate Wildlife of Alabama" (Mount, 1984) and "Vertebrate Animals of Alabama in Need of Special Attention" (Mount, 1986) . Both these publications were concerned with vertebrates with no consideration given to the invertebrate fauna of Alabama. The purpose of this paper is to provide a preliminary accounting of selected groups of invertebrates in Alabama which might be considered rare, insufficiently known, or in need of special attention. Invertebrates as a group constitute about 95% of all known animal species, the overwhelming majority of which are arthropods (Barnes, 1980). They occur in virtually all habitats and are enormously important from both an ecological and economical standpoint, yet as a group they have been little studied in Alabama. This lack of detailed knowledge of the invertebrate fauna of Alabama accounts in part for their exclusion from recent compilations of rare or endangered species. Our knowledge of the invertebrates, though far from complete, is improving and invertebrates are included by several southeastern states in listings of threatened or endangered species (Table 1) . South Carolina has compiled the most ex¬ tensive list, followed by Florida, with both states including terrestrial and aquatic taxa. In Alabama, we are beginning to document a portion of ’This article was presented as an invited paper at a Symposium on the Status of Endangered Species in Alabama on 24 March 1989 at the annual meeting of the Alabama Academy of Science held at Birmingham- Southern College, Birmingham, Alabama. 64 Harris Table 1.

Even here much of our knowledge is limited to the larger aquatic invertebrates, for example the mollusks and some aquatic insects, with terrestrial and microscopic invertebrates remaining poorly known. Our meager knowledge of the invertebrate fauna of Alabama also presents difficulties when attempting to assign species to the standard protected categories of endangered, threatened, or special concern. One possible exception is the Mollusca, which have been studied extensively enough in Alabama to allow placement of some species in the protective 65 Rare and endangered invertebrates in Alabama categories. Stein (1976) and Stansbery (1976) assigned protective cate¬ gories to gastropods and naiad mollusks, respectively, and 11 mollusks from Alabama are listed as threatened or endangered by the U.S. Department of the Interior (Table 2). Crayfishes in Alabama, although still incom¬ pletely known, are often so limited in distribution that some species may be assigned to protective categories. A preliminary list of the cray¬ fishes and freshwater shrimps of Alabama, which listed one species as threatened, was compiled by Bouchard (1976). In 1988, the freshwater shrimp, Palaemonias alabamae was proposed for listing as threatened by the U.S. Department of the Interior. Most insects in Alabama, are not easily placed in the protective categories of endangered, threatened, or special concern. As with the Table 2.

While invertebrates such as mollusks and crayfishes may be restricted to a specific drainage or habitat, insects have the capability to move easily. 2. ) Life history complications: With insects, as well as other invertebrates , the identification of a species is often dependent on a specific life history stage, usually late instar immature s or adult males. With most aquatic insects, the immatures are collected from the water, while the adults are terrestrial. 3. ) Size: Insects and most invertebrates are small and are identi¬ fied to species on the basis of small morphological characters, often only observable by specialists. Generally the specimens must be killed and preserved in order to make specific identifications. 4. ) Public Perception: With most insects and arachnids being per¬ ceived by the general public as a nuisance or dangerous, assigning such organisms to protected status is difficult. With these points in mind, most of the invertebrate specialists con¬ tacted and asked to compile lists of species considered rare in Alabama were unable in many cases to assign such species to the categories of endangered, threatened, or special concern. In most cases those species listed are limited or restricted in their occurrence in Alabama. Even assigning species to such a broad category as "restricted in occurrence" can be misleading as several examples from the caddisflies (Trichoptera) , a common group of aquatic insects, will illustrate. The leptocerid Ceraclea alces occurs in the north central United States and in the Little River of northeastern Alabama . Within Alabama the species in certainly restricted in distribution, yet whether this represents a disjunct popu¬ lation or merely reflects inadequate collecting in eastern and central United States is unknown . The same situation applies to the microcad- disfly Hydroptila lennoxi which is known only from New Hampshire and Chilton County , Alabama. This problem of discerning whether a species is truly restricted or merely an artifact of inadequate collecting is illustrated by looking in more detail at those species of caddisflies with restricted distributions in Alabama. Of the approximately 325 species in the state , about one- third appear to be restricted in occurrence . However, nearly half of these rare species are only known from a single location or collection and 86% are known from three or fewer locations (Fig. 1). The same situation exists in the abundance of these rare species , with 20% known from a single specimen and 80% known from less than 10 specimens (Fig. 2) . The following sections present a preliminary compilation of those species of aquatic invertebrates considered rare or restricted by the 67 Rare and endangered invertebrates in Alabama C/3 UJ O HI CL C/3 HI I— a_ O X a cr ac UJ m 2 NUMBER OF LOCAUTIES Figure 1.

In some cases the fauna is sufficiently known to apply the categories of endangered, threatened, or special concern; in others, the species are simply restricted in their occurrence in Alabama. Also with some groups, their distribution within Alabama is well docu¬ mented and allows some reliability in placing a species within a certain habitat or drainage; in others, only records of occurrence within a county are available at this time. Although this makes for a somewhat loose format, it is a reflection of the state of our present knowledge of invertebrates in Alabama. MGLLUSCA: Prepared by Paul Yokley, Jr. , Department of Biology, University of North Alabama, Florence , AL 35632 Mo Husks are among the most conspicuous of invertebrates and include the familiar freshwater mussels, clams, and snails, as well as oysters, squids, and octopods . In freshwater, mo llusks are divided into two classes: Bivalvia , the clams and mussels, and Gastropoda, the snails and limpets. Both groups are immediately recognized by either a flattened or conical shell which covers the body. Mollusks occur in virtually all types of aquatic habitats from springs and streams to large rivers, ponds, marshes, and lakes. Generally they are found in shallow waters on stable substrated . Water quality is of importance to mollusk populations with clean, alkaline waters supporting more species than impacted waters, low in dissolved oxygen. Since mollusks have limited mobility, many species are restricted to specific drainages or habitats. Detrimental changes to these habitats often results in the loss of the endemic mollusk popula¬ tion.

F. Fitzpatrick, Jr., Department of Biological Sciences , University of South Alabama, Mobile, Alabama 36688 The Decapoda are the largest order within the Crustacea and include as members the freshwater crawfishes and shrimps. Crawfishes are familiar to most aquatic biologists as they are common inhabitants of shallow waters, including lakes, ponds, swamps, sloughs, streams, and rivers, as well as wet areas in meadows and roadside ditches. While many species of crawfish are found in open waters, others build burrows in the vicinity of water, with some rarely venturing out of these burrows. Most species that in¬ habit temporary or seasonal waters will burrow into the substrate during dry periods, and a few species seem to be completely divorced from any open water. The freshwater shrimps, also called prawns or grass shrimp, are generally inhabitants of the large rivers and permanently flowing creeks , although the genus Palaemonias in Alabama occurs in subterranean pools. A checklist of the Decapoda of Alabama was provided by Bouchard (1976), but a much more complete and up-to-date reference for the craw¬ fishes is Hobbs (1989). Bouchard's list identified 58 species of craw¬ fishes and 6 shrimps, of which 14 were considered to be threatened or of special concern status in Alabama. He mentioned that his compilation was preliminary with a state fauna of approximately 75 species of crawfishes likely with a thorough survey; true of his predictions, several taxa have been described since then and at this writing, more are "in press."

EPHEMEROPTERA : Prepared by Steven C. Harris, Biological Resources Division, Geological Survey of Alabama, Tuscaloosa, Alabama 35486 and Boris C. Kondratieff, Department of Entomology , Colorado State University , Fort Collins, Colorado 80523 Mayflies, which are commonly known as "willow flies," occur throughout Alabama in most types of freshwater, from rivers and streams to lakes and ponds. The adults, during periods of emergence or nuptial flights (swarm¬ ing), are often present in enormous numbers, particularly along large rivers and lakes, forming dense clouds around lights and covering the ground. The nymphs are aquatic and while occurring in a wide variety of habitats, they all generally require high levels of dissolved oxygen. This requirement often allows the group to be utilized by aquatic biol¬ ogists as indicators of clean waters. A preliminary checklist of the mayflies of Alabama was compiled by Kondratieff and Harris (1986) . To date 114 species have been reported from the state, 13 of which are rare or restricted in distribution.

Tennessen, 1949 Hickory Avenue, Florence , Alabama, 35630 Odonates are conspicuous insects flying along the waterways of Alabama. The adults are familiar to most people and are often called "snake doctors" or "darning needles." Their diversity in color, size, and behavior make them ideal subjects for observation. The immatures are aquatic and live along the margins of water bodies, often amidst vegeta¬ tion. The Odonata are divided into two suborders, the Anisoptera or dragonflies and the Zygoptera or damselflies. In Alabama, 157 species of odonates have been identified, of which 49 are rare or restricted in distribution.

Stark, Department of Biological Sciences , Mississippi College, Clinton, Mississippi 39058 The Plecoptera, or stoneflies, are usually found in association with cool, clean streams. The nymphs are aquatic and live under rocks or debris on the stream bottom, while the adults are terrestrial, although 83 Rare and endangered invertebrates in Alabama they are seldom found far from the stream margin. Since the nymphs usually require habitats high in dissolved oxygen and low in silt, the group is often utilized by aquatic biologists as indicators of clean, unpolluted streams. Checklists of the stonefly fauna of Alabama were compiled by James (1972) and updated by Stark and Harris (1986).

Harris, Biological Resources Division , Geological Survey of Alabama, Tuscaloosa , Alabama 35486 The Trichoptera, or caddisflies , are small moth- like insects as adults; as larvae they are aquatic. Caddisfly larvae are notable for the feeding nets constructed by some groups and the portable cases of rocks and leaves constructed by others. Most freshwater aquatic habitats, ranging from streams and rivers to lakes and ponds , have a trichopteran fauna. Caddisflies are most abundant and diverse in clean waters high in dissolved oxygen and they are often utilized by aquatic biologists as water quality indicators. Alabama has a rich caddisfly fauna with over 325 species (Harris, 1986; Lago and Harris , 1987 ; Harris and Lago , 1990) , of which 112 may be considered rare or restricted in occurrence in the state .

Harris, Biological Re¬ sources Division, Geological Survey of Alabama, Tuscaloosa , Alabama 35U86 The beetles constitute the largest group of insects, but only about 2% of all species are aquatic or semiaquatic. Beetles occur in a wide array of habitats from streams and lakes to brackish estuaries and marshes, but rarely are they found in large numbers. Most of the aquatic beetles live close to the bottom, but some such as the Dytiscidae are efficient swim¬ mers. Other beetles, such as the Gyrinidae have adapted to live on the water surface, and some groups are semiaquatic occuring at the water margin. While the beetle fauna of Alabama is incompletely known, several studies are available, including Loding (1945), Folkerts (1978), and Eiland (1979).

Holliman Division of Science and Mathematics Birmingham- Southern College Birmingham, AL 35254 ABSTRACT The status of those birds and mammals listed in Vertebrate Animals of Alabama in Need of Special Attention (Mount 1986) is reviewed. Status changes and data gaps are detailed for other birds and mammals that were not included in the proceedings of the 1983 Alabama First Nongame Wildlife Conference. Critical habitats and stress sources are described. A research and management program along with specific jobs within these programs are listed by priority. A basic philosophy relative to the implementation of the program encourages rangewide studies, cooperation among educational institutions, and the utilization of ongoing state and federal activities. INTRODUCTION The purpose of this paper is to update the status of those birds and mammals listed in Vertebrate Animals of Alabama in Need of Special Atten¬ tion (Mount 1986). Comments are made only about those species that should be reexamined. The objectives are to indicate any status changes, data gaps , critical habitats , and stress sources that were not previously addressed; and to propose a research and management program along with specific jobs, by priority, within these programs. The bird and mammal committee of the 1986 symposium recommended the following status for each of these species: ALABAMA BIRDS NEEDING SPECIAL ATTENTION (Mount, 1986) SPECIES CURRENT PROTECTION ENDANGERED Wood stork Bald eagle Sandhill crane Snowy plover Federal (endangered status) , State Federal (endangered status) , State Federal (endangered status) , State Federal, State ’This article was presented as an invited paper at a Symposium on the Status of Endangered Species in Alabama on 24 March 1989 at the annual meeting of the Alabama Academy of Science held at Birmingham- Southern College, Birmingham, Alabama. 93 Holliman Red-cockaded woodpecker Federal (endangered status) , State Bachman's warbler Federal (endangered status) , THREATENED State Golden eagle Federal, State Peregrine falcon Federal (endangered status) , State Bewick's wren Federal, State SPECIAL CONCERN American white pelican Federal, State Reddish egret Federal, State Mottled duck Federal, State Osprey Federal, State Cooper's hawk Federal, State Merlin Federal, State Wilson's plover Federal, State Piping plover Federal (Threatened status) , State American oysterchatcher Federal, State Gull-billed Tern Federal, State Common ground dover Federal, state POORLY KNOWN Yellow rail Federal, State Black rail Federal, State Long- eared owl Federal, State Northern saw-whet owl Federal, State Alder flycatcher Federal, State Willow flycatcher Federal, State Warbling vireo Federal, State Henslow's sparrow Federal, State Le Conte's sparrow Federal, State ALABAMA MAMMALS IN ] NEED OF SPECIAL ATTENTION (Mount, 1986) ENDANGERED Gray myotis Federal (Endangered status) Indian myotis Federal (Endangered status) Alabama beach mouse Federal (Endangered status) Perdido key beach mouse Federal (Endangered status) Mountain lion Federal (Endangered status State SPECIAL CONCERN ) and Southeastern myotis None Rafinesque's big-eared bat None Brazilian free -tailed bat None Southeastern pocket gopher None 94 Alabama birds and mammals Meadow jumping mouse Black bear None State POORLY KNOWN Northern yellow bat Marsh rabbit New England cottontail J aguarundi California sea lion None State (seasonal) State (seasonal) Federal (endangered status) None Both committees recommended these determinations realizing that such judgements are dependent upon extreme environmental changes and the accumulation of knowledge as well as the education of the general public. In most determinations these above factors are unknown entities that make it necessary to periodically review status designations for the welfare of the species. Priority categories were as follow (Mount, 1986): Endangered . Forms in danger of extinction or extirpation in all or in a majority of their range in Alabama within the foreseeable future. Threatened . Forms likely to become endangered in all or in a majority of their range in Alabama within the foreseeable future. Special Concern. Forms that must be continually monitored because of imminent threats to the habitat, limited range in Alabama, or because of other physical or biological factors that may cause them to become threat¬ ened or endangered within the State in the foreseeable future. Poorly Known . Forms for which data on status, distribution, and/or life history are insufficient to permit categorization otherwise. These should be among the top candidates for expenditures of funds and re¬ sources . The information and recommendations given in this report were gathered from many sources. Committee members from the previous symposium, other workers in the field, and my own observations and work with certain spe¬ cies have supplied data that is reflected in this paper. It should be noted that the status determination for any species of vertebrate is a continuing process and that this process should be closely monitored if we are to serve as prudent stewards for our fauna and flora. RESULTS AND DISCUSSION The following is a recommendation for a resource plan for selected birds and mammals that were listed in Vertebrate Animals of Alabama in Need of Special Attention (Mount, 1986). Only those species that were judged to require reexamination are discussed. Hopefully at the next symposium other species that were not considered in this paper will be the object of discussion. Undoubtedly there will be others. The major areas or programs for recommend funding are listed in an order of priority. 95 Holliman Table 1. Recommendations for a resource plan for birds and mammals.

As scientists we sould stand ready to identify the habitat needs of our fauna and flora so that habitat aquisi¬ tion can be justified. It is not within the purviews of this paper to catalogue potential habitat that could be secured through the various state, federal, and private organizations. This has been done elsewhere. B. Habitat studies. Certainly if one takes a holistic view of the broad spectrum of the state's environmental problems, an argument could be marshalled for the importance of any research or management project concerning the welfare of a species. Elsewhere in this symposium Dr. George Folkers will talk about the wide variety of habitats in the state and will address problems that are indigenous to each. Time and space will not permit me to analyze all of the habitat needs for birds and mammals, but I would briefly like to point out several habitats that need to be closely watched. Spartina marshes, predominantly Spartina altemiflora (smooth cordgrass) with limited amounts of Juncus roemerianus (black needlerush) , have slowly disappeared within the last ten years. Four thousand- four hundred and ninety hectares were mapped in 1978 (Holliman, 1978) . Hur¬ ricane Frederick on the evening of September 12, 1979 (Holliman, 1981) washed over- most of this wetland with no apparent long term damage to vegetative communities. Bordering these marshes are interdigitations of saltbush- saltflat habitat characterized by Baccharis halimifolia (salt bush), Iva fruCescens (marsh elder), Salicomia sp . (glasswort) , BaCis maricima (saltwort), Distichlis spicata, and mats of bluegreen algae and diatoms. Savannah lands with Spartina patens (saltmeadow cord grass), Pinus elliotii (slash pine), Pinus palustris (long-leaf pine), Taxodium distichum (cypress), various species of sedges and rushes, and Sarracenia sp. (pitcher plants) form a fringe along the mainland border of the saltbush- saltflat complex. All of this is fairly typical of the existing marshlands along the coast of southern Mobile County. In southern Baldwin County there are limited amounts of the beach- sand dune habitat. In 1983 (Holliman, 1983, 1982) there were approximately 134.6 ha of beach mouse habitat primarily consisting of primary, secondary, and teritary dunes vegetated with Uniola paniculata (sea oats), Spartina patens (saltmeadow cordgrass), Hydrocotyl bonariensis (pennywort), and Panicum amaium (bitter weed). On the mainland edge of this critical habitat beginning with the tertiary sand dunes can be found Quercus virginica var. maritina (live oak), Pinus elliottii (slash pine), Pinus clausa (sand pine), Seronoa repens (saw palmetto), Ilex vomitoria (yaupon) , Ceratiola ericoides (seaside rosemary) , and Solidago pauciflosculosa (seaside goldenrod) . The relict dune system, and accompanying swamp land, with Taxodium distichum , T. ascendens (cypress), Salix nigra (willow), Magnolia virginiana (white bay), Nyssa biflora (black gum), Cliftonia monophylla (titi) , and Pinus serotina (pond pine), is now mostly preserved in the Bon Secour National Wildlife Refuge. These four habitats (saltmarsh, saltbush- saltflat , savannah, and beach- sand dune) support a significant number of mammal and 97 Holliman bird species. The Alabama coast line, although limited, is the focus point for migrants in the spring, and is a staging area in the fall for birds tracking back and forth from Central and South America. The Mobile Delta, essentially resembling the swamp land found in the Bon Secour National Wildlife Refuge, provides breeding and feeding habitat for colonial nesting birds. Dindo (1989) has documented the fierce competition among colonial nesters for nesting space on Cat Island in Portersville Bay. Holliman (1984) described the growth of Gaillard Island in terms of exploitation of available nesting territories by shore birds. The State of Alabama, Department of Conservation and Natural Resources is presently monitoring bird utilization of this spoil island in Mobile Bay. Another habitat that we may be overlooking is the boundary between brackish-mixed and fresh-mixed marshes along our coastal rivers. This interface is marked by the upstream presence of Typha angustifolia , T. laCifolia (cat tails), Sagittaria falcata (duck potato), Zizania aquaCica (wild rice), Zizaniopis miliacea (cutgrass), Scirpus americanus (three square) , Cladium jamaicenere (saw grass) , and Vigua repens (cow pea) . Here clapper and king rails may interbreed. I have suspected the presence of intermediate forms during call count surveys along coastal rivers in previous years. Other rail species and gallinules may use this transi¬ tional habitat during migration through the southeastern U. S. (Holliman, 1977). Upstate isolated swamps associated with Karst topography are being altered by the manipulation of water tables. Such a wetland is located in north Shelby County immediately west and contiguous to the Shelby County airport. Tree species include Quercus nigra (water oak), Acer rubrum (red maple), Nyssa sylvatica (blackgum) , N. aquatica (tupelo gum), and N. s. var biflora (swamp tupelo). These scattered swamps provide stopover areas for migrating and resident waterfowl as well as habitat for other wildlife species . The evaluation and inventory of existing habitat should be a con¬ tinuing process. Flora signatures are yet to be determined for many indicator plant species. Without these ground truth surveys interpreta¬ tion of remotely sensed imagery is difficult, particularly when one is attempting to locate microhabitats. For an example, we know now that clapper rail habitat requires proportional amounts of different vegetative types; and it is important to be able to measure this moasic pattern. The improvement of habitat by landowner subsidy is at the embryonic stage in this state and will indeed be a challenge for those state and federal agencies who are charged with this responsibility. Educators have done a poor job in helping the general public formulate a land ethic. There must be a balance struck between lands used for hunter harvest and other forms of wildlife. Habitat preferences remain to be determined for certain species. Migratory bats require roosts and hunting areas. The degree of utili¬ zation of caves and other structures needs to be evaluated before we can 98 Alabama birds and mammals adequately protect these mammals. We need to "fine tune" our knowledge concerning habitat preferences for such species as the sea side sparrow, reddish egret, piping and snowy plovers, and the long nose shrew. The following problem areas related to habitat studies need additional research: 1. Determination of snowy plover and American oyster catcher utilization of coastal islands. 2. Location of nesting birds colonies in the Mobile Delta. 3. Identification of floral signatures in Spartina marshes for remote sensing and ground truth studies. 4. Habitat requirements for the black rail in Alabama. 5. Habitat preference for both long nose and least shrew in Alabama. C. Public Education. We need to expand educational efforts that are directed towards habitat protection and endangered species. The Nongame Program of the State of Alabama is to be commended for its efforts to attempt this monumental task. Their efforts to publicize the plight of the bald eagle, osprey, and blue bird are spartan, given their present level of funding and other forms of support. As educators and scientists we need to galvanize support for this program by providing technical knowledge. On our coast the Marine Sciences Consortium serves as a model of what re¬ source education should be. With their educational and research programs the Dauphin Island Sea Lab is providing a center for learners and re¬ searchers alike. The Birmingham Audubon Society has been sponsoring the Mountain Ecology Workshop at Mentone since May 1977 and should be com¬ mended for efforts in conservation education (Holliman, 1984) . The following problem area related to public education needs additional attention: Scientists and educators of the colleges and universities of Alabama should insist that courses be offered in their curricula that emphasize a holistic view of environmental education. The Alabama Academy of Science could well serve as a forum where there can be an interchange of ideas and philosophies . D. Harvest. We would do well to come to the realization that game and non- game research and management practices are compatible. They should go hand in hand. For an example, one can have both Canada geese and Carolina wrens by leaving brush piles along the edge of land that has been cleared for winter oats. The wildlife dollar can benefit both game and non game programs at the same time. We've yet to learn whether the marsh rabbit, 99 Holliman bayou gray squirrel, the woodland and western cottontails, and rails turn up in the hunter's bag. The following problem areas related to harvest need additional attention: Gather hunter harvest data to determine presence of rail species, New England cottontail, and marsh rabbits and bayou gray squirrels in hunter's bag. E. Population dynamics. The federally administered Breeding Bird Survey (BBS) begun in 1966 has provided significant data relative to our breeding bird population. The BBS now consists of approximately 2,000 randomly selected routes throughout the United States and Canada that are surveyed each breeding season from the last proper week in May to the end of the second week in June. These roadside surveys (starting 1/2 hour before sunrise) use a standardized technique consisting of recording all birds heard or seen in 3 minutes at 50 stops, each 1/2 mile apart. A "route regression" method is used to estimate the trend in percent of change per year. Individual route estimates are weighted by the number of birds on the route, the area of the state or other geographic region, and the sample size of routes within that region. Those weighted estimates are then converted to percent change per year. The survey procedure is more fully described by Robbins, Bystrak, and Geissler (1986). Based on 22 years of data from 1966 to 1987 Reid and Droege (1989) determined some significant decreases in population of Alabama birds (Table 2). Trends are expressed in percent of change per year. Sig¬ nificance of trends is indicated by asterisks: * - significant at P less than 0.05 level; ** - highly significant at P less than 0.01 level. It will be noted that, of the 13 species presented, eight are tropical or subtropical migrants. Three (the wood pewee and yellow and cerulean warblers - the latter now not being found with any regularity in Alabama outside the Bankhead Forest) winter in South America, two (the blue- winged warbler and orchard oriole) in Central America and Northwest South America, and the other three (the wood thrush, prairie warbler, and chat) in Central America and the West Indies. Five might be classed as edge of scrub species and three as birds of the forest. The major causes of their decline appear to be forest fragmentation on the breeding range and de¬ forestation in the wintering range. The latter is considered the primary cause since during the last 10 years of the Breeding Bird Survey (1978- 87) , which coincides with the greatest increase in tropical deforestation, neotropical migrants have decreased more than species that winter north of Central America, and forest-wintering tropical migrants have decreased at a greater rate than migrants that winter in open habitats (see Robbins, C.

In addition, the decrease in Orchard Oriole in Alabama is significant at the P less than 0.10 level.) Holliman the Coastal Plain, plus the smaller decreases of the Prairie Warbler in those regions, is probably due to the increase in even-age forest manage¬ ment (clear cutting) ; and it has been said that the Grasshopper Sparrow benefits from strip-mine reclamation, which may account for its increase in the Piedmont, although that cause would leave the decreases in other mountainous regions unexplained. Decrease in the flicker is attributed largely to competition for existing nest holes from the starling and perhaps due to a reduction in number of dead trees left standing in edge and woodlot areas. The shrike appears to be suffering from a multiplicity of changes in land-use practices, including surburban sprawl, roadside spraying, and loss of pastureland and hedgerows. The towhee is thought to be suffering seriously from cowbird parasitism as might also be the case with the field sparrow. In addition this species and the grasshopper sparrow doubtless are being impacted by the loss of pastureland as are all grassland species. Highly significant annual percentage declines have also been shown by the BBS over a 20-year period (1966-1985) for the following species that winter in Alabama or migrate through it: yellow- bellied sapsucker (-3.886), olive-sided flycatcher (-3.754), golden- crowned kinglet (-3.782), golden-winged warbler (-3.208), white- throated sparrow (-2.032), and white -crowned sparrow (-2.690). Reid has con¬ tributed significantly to the knowledge of our breeding bird populations by compiling and analyzing the accumulated BBS data. Some unanswered problems are yet to be solved. Declines in the northern harrier, American Kestrel, ground dove, and loggerhead shrike have been noticed. Little is known about the. marine mammals that frequent Alabama waters (Holliman, 1979). Southward, beyond the three mile limit and within the territorial waters, there are scattered records of both whales and dol¬ phins (Table 3). Inside the three mile limit the bottle-nosed dolphin is clearly the most common species. It is encountered in about equal numbers throughout the year. Occasional individuals move well into the mouth of Weeks Bay and even into Fish, Magnolia, and Bon Secour rivers. Little is known about their seasonal movements, and the location of their calving and feeding grounds. The possible effects of poaching, malicious killing, and harrassment are not known. It is highly probable that the manatee is a frequent visitor to Alabama waters. Various unconfirmed reports of this mammal have come from several boat captains operating out of Bayou la Batre in recent times. In Mississippi a single manatee was sighted in Wolf River on January 1, 1979 (telephone call March 20, 1979 to J. Corcoran, Gulf Coast Research Laboratory, Ocean Springs, MS 39564)). A second sighting of this same individual was made on January 3, 1979 in a small craft harbor at Gulfport. Finally on January 6, 1979, the manatee was captured and transported to Sea World in Florida where it was treated for pneumonia. There is no information available to the author as to whether subspecific identification was determined for this specimen. It appears that the manatees from the eastern Gulf of Mexico represent the subspecies Trichechus manatus latirostris , while those from Louisiana, Texas, and Mexico represent the subspecies Trichechus manatus manatus. 102 Alabama birds and mammals Table 3.

Some two weeks later pods of hump backs and sperm whales were seen in approximately the same location. Veron Menton, (State of Alabama Conservation Department, personal communication, 1989) recorded manatees in Perdido Pass in 1988, and again at Gulf Shores in 1989. Bob Shipp (personal communication, 1989) observed a single manatee in the early 1980' s in Fowl River, Mobile County. The status of all marine mammals should be updated. Hopefully this subject will be treated at our next symposium. The Non Game Program has mounted a successful eagle hacking project with promising results for this bird. The Department of Conservation and Natural Resources is to be commended for their support of the Non Game Division. 103 Holliman For a long time Bob Mount and myself and others have been speculating as to the decline in striped and spotted skunk populations. These mammals along with such ground nesting birds as the eastern meadow lark are simply not as conspicuous as they were 40 years ago. Perhaps it was a combina¬ tion of factors such as the indiscriminate use of pesticides and habitat alterations. This may also be tied with the high incidence of rabies in raccoons and bats in the southeast because of a decline in normal reser¬ voir species, the skunks. Mammals that are on the increase include the nine-banded armadillo, coyote, and black bear. Armadillos are now so common in east Tuscaloosa County that they can be seen during the day in certain areas. There is a population of coyotes that may be seen at the Wheeler Wildlife Refuge, Reports of black bears are numerous, particularly in the Mobile Delta and Yellow Leaf Creek drainage in Shelby County. Studies in the Black Belt (Holliman, 1978) suggest that the common snipe may be a resource that is being overlooked. The following problem areas related to population dynamics need additional research: 1. Conduct distributional studies on the bewick wren, mottled duck, black rail, kestrel, and all bat species. 2. Reevaluate the status of the New England cottontail and j aguarundi . 3. Continue density studies on all known colonial nesters, particularly in the coastal zone. 4. Conduct heavy metal and pesticide studies on breeding shore birds. 5. Conduct rabies studies in bat and raccoon populations. LITERATURE CITED Dindo, J. J. 1989.

Malcolm Pierson Department of Environmental Affairs Alabama Power Company P. 0. Box 26A1 Birmingham, AL 35291 ABSTRACT Approximately 300 species of freshwater fishes have been documented from the State of Alabama. Ten of these fishes are found only in Alabama, while Alabama waters represent over 60 percent of the total range of an additional 37 species. In a recent publication (Mount 1986), 18 species of freshwater fishes were assigned some level of conservation status. The Cahaba shiner, Alabama cavefish, spring pygmy sunfish, and watercress darter were given endangered status and the paleband shiner, slackwater darter, goldline darter, snail darter, and pygmy sculpin were assigned threatened status. An additional nine species were designated as either special concern or poorly known. This report updates the status of these 18 species and in some cases suggests studies to assess the current status of these and other sensitive fishes in Alabama waters. INTRODUCTION The first Nongame Wildlife Conference in Alabama was held at Auburn University in July 1983 and was jointly sponsored by the Alabama Depart¬ ment of Conservation and Natural Resources and the Alabama Agricultural Experiment Station. Prior to the state's Nongame Wildlife Program created in 1982, nongame vertebrates received little attention unless they were federally listed as either threatened or endangered. The results of this nongame conference were two publications: "Vertebrate Wildlife of Ala¬ bama" published in 1984 and "Vertebrate Wildlife of Alabama in Need of Special Attention" published in 1986. The purpose of this report is to note any changes in the conservation status of fishes which were listed in Mount (1986) or to mention other species which may need further study or which may deserve some type of conservation effort. Alabama ranks second only to Tennessee in number of strictly fresh¬ water fish species with approximately 300 known from Alabama waters . This is due primarily to the diversity of aquatic habitats, the number of major river systems which drain our state, and the absence of early glacial scouring. xThis article was presented as an invited paper at a Symposium on the Status of Endangered Species in Alabama on 24 March 1989 at the annual meeting of the Alabama Academy of Science held at Birmingham-Southern College, Birmingham, Alabama. 106 Pierson While most species of Alabama fishes are represented by large, stable, reproducing populations, this report concerns species which are considered either very rare or species which have a restricted range and could be vulnerable to environmental stress or other alterations to their preferred habitat. The conservation status of the 21 species covered in this status review is an indicator of their environmental sensitivity. Most are highly fastidious "specialists" that are competitively excluded from other habitats (Ramsey 1986). The first five species to be discussed are listed as endangered by the State of Alabama. The next five species are considered threatened, six are listed as special concern, and seven are designated poorly known. ENDANGERED NoCropis cahabae Mayden and Kuhajda Cahaba shiner RANGE - Historically, the Cahaba shiner was known only from the main channel Cahaba River from about 11 kilometers below Centreville upstream to Helena, a distance of about 95 river kilometers. In recent years, the Cahaba shiner has been collected at several localities from near Heiberger (Perry County) upstream to Hancock Creek in Shelby County. STATUS - Several workers have recently collected the Cahaba shiner in the main channel at the Highway 27 locality above Centreville, however, none have been recently collected upstream of Piper Bridge. Thorough distribu¬ tion studies by Howell et al. (1982); Ramsey (1982), and Pierson et al. (1989) revealed the Cahaba shiner to be quite rare even in its preferred habitat. A formal description of this species has been recently published by R, L. Mayden and B. R. Kuhajda. The U. S. Fish and Wildlife Service (USFWS) Office of Endangered Species plans to propose threatened status for this shiner. COMMENTS - Based on these recent developments, it appears that the Cahaba shiner should retain its present endangered status at the state level. Known populations should be monitored and newly reported records below the Fall Line should be investigated to determine if these represent perma¬ nent, reproducing populations. Speoplatyrhinus poulsoni Cooper and Kuehne Alabama cavefish RANGE - The Alabama cavefish is known only from Key Cave in Lauderdale County, Alabama. This species is threatened by low population levels, low reproductive rate, and a very restricted range (Ramsey 1986). STATUS - Continued existence at the type locality was confirmed in late 1983, when sightings were made in several pools of Key Cave (Ramsey 1986). The status of the Alabama cavefish was changed from threatened to en¬ dangered by the USFWS Endangered Species Office in October 1988. The USFWS has contracted Underground Labs, Inc. to study the hydrology of Key Cave and the surrounding area. 107 Status of Alabama fishes COMMENTS: This is one of the rarest of North American vertebrates, and for this reason it should retain its endangered status in Alabama. Elassoma sp. spring pygmy sunfish RANGE - This undescribed Alabama endemic historically was confined to several well -vegetated springs or spring runs in the Tennessee River drainage (Mettee 1986). After the impounding of a portion of the Tennes¬ see River by Pickwick Dam, this species was believed to be extinct until 1973 when Dave Etnier and others collected specimens from Beaverdam Spring in Limestone County. Subsequent sampling found other populations within the Beaverdam Creek watershed. STATUS - In 1984-1985 M. F. Mettee and others reintroduced pygmy sunfish into Pryor Spring. Successful reproduction has been recorded for three consecutive years. A second introduction was attempted in a headwater spring in 1988. At the present time the result of this introduction is not known. A renewable conservation agreement with two landowners has been obtained, and overall the population appears to be doing well (M. F. Mettee, personal communication). Etheostoma nuchale Howell and Caldwell watercress darter RANGE - This federally endangered Alabama endemic is restricted to a small area in the upper Black Warrior River system in Jefferson County. For¬ merly known only from Glenn, Thomas, and Roebuck springs it has recently (January 1988) been introduced into Avondale Spring and Tapawingo Plunge Springs at Pinson. A man-made pond below Thomas Spring now contains an abundance of watercress darters. STATUS - The Glenn Spring population is apparently stable but the Roebuck Spring population has been slowly declining. There is run-off from nearby streets and a service station and some herbicide run-off from a golf course (Mike Howell, personal communication). The Tapawingo Plunge Spring population has had a successful spawn in 1988 and 1989. Mike Howell reported observing adults, subadults, and fry in the Summer of 1989. Etheostoma wapiti Etnier and Williams boulder darter RANGE - This recently described darter is presently restricted to a 60 mile section of the Elk River in the Tennessee River system of Alabama and Tennessee. No specimens have been reported from Shoal Creek since the late 1800's. Less than 60 specimens of this elusive species have been collected. STATUS - The USFWS Endangered Species Office issued a final rule for endangered status on October 3, 1988. Attempts to collect additional specimens from the Shoal Creek system in 1983 and 1986 were unsuccessful, however, suitable habitat in the Shoal Creek system could result in a new successful population if the boulder darter is reintroduced (Jim Williams, personal communication) . 108 Pierson COMMENTS — Since the USFWS has considered this species deserving of en¬ dangered status at the federal level, and the State of Tennessee lists this species as endangered, it would seem appropriate to assign the boulder darter endangered status in Alabama. This species has recently been described by James D. Williams and David A. Etnier. THREATENED Notropis sp. cf. procne paleband shiner RANGE - The paleband shiner is restricted to a three mile stretch of the Paint Rock River in Madison and Jackson counties, Alabama. This popula¬ tion was discovered while searching for additional populations of snail darters . STATUS - Rechannelization is being considered for the Paint Rock River and constitutes a potential threat (Tom Jandebeur, personal communication). COMMENTS - The present threatened status in Alabama is probably still applicable to this species. Surveys should be undertaken to determine the present range of the paleband shiner in the Tennessee River system of Alabama . Etheostoma boschungi Wall and Williams slackwater darter RANGE - The slackwater darter is restricted to tributaries of the Southern Bend of the Tennessee River, in northern Alabama and Tennessee, and to one area of the Duck-Tennessee basin in western Tennessee (Ramsey and Boschung 1986). In Alabama, most of its range is in the Cypress and Swan Creek watersheds and the Flint River system in Lauderdale, Limestone, and Madison counties. STATUS - The range of the slackwater darter and its known habitat within this range are limited. As recent as the mid 1980' s the Cypress Creek population was generally widespread and successful; however, suitable spawning habitat is decreasing due to farm pond and beaverdam construction (Ramsey and Boschung 1986) . COMMENTS - The present threatened status in Alabama should probably be retained. Percina aurolineata Suttkus and Ramsey goldline darter RANGE - Historically, in Alabama the goldline darter has been collected from the main channel of the Cahaba River from Centreville upstream to Helena and in the lower Little Cahaba River. In recent years no specimens have been collected in the main channel above Piper. Goldline darters have also recently been reported from lower Sixmile and Schultz creeks in Bibb County (Pierson et al. 1989). STATUS - Apparently, siltation from upstream developments, organic enrichment, and/or mining operations have reduced or eliminated goldline 109 Status of Alabama fishes darter populations from the upper main channel. Recent run-offs from a wood treatment plant have resulted in fish kills in the Little Cahaba and an apparent decrease in goldline darter numbers. COMMENTS - The threatened status of the goldline darter should be retained unless further degradation of the main channel or Little Cahaba occurs; in which case endangered status may be more appropriate. Known populations should be carefully monitored for sudden changes in status. Percina tanasi Etnier snail darter RANGE - In Alabama the historic range is unknown since almost no col¬ lections were made in the Tennessee River and its major tributaries before impoundment. The sole existing Alabama population was discovered in the Paint Rock River between river mile 16 and 19 in 1981 near the Jackson- Marshall County boundary (Jandebeur 1986). STATUS - The preferred habitat of the snail darter in Alabama has been relatively stable since its discovery. It is unknown how the Paint Rock population discovered in 1981 is doing presently. The Paint Rock was channelized in 1966 and some consideration has been given to proposals for rechannelization (Tom Jandebeur, personal communication). Percina tanasi is currently recognized as threatened at both the state and federal level. COMMENTS - The Paint Rock River population should be monitored regularly and adjacent watersheds should be searched for additional populations. Cottus pygmaeus Williams pygmy sculpin RANGE - The pygmy sculpin is known only from Coldwater Spring, the spring run, and a small section of Coldwater Creek, a tributary to Choccolocco Creek in the Coosa River system in Calhoun County, Alabama (Boschung 1986). STATUS - Coldwater Spring is the major water supply for the City of Anniston which works to the advantage of the pygmy sculpin. In the past the City of Anniston has had a cooperative agreement with the USFWS providing that "no action be taken which would endanger the pygmy scul¬ pin" . In February of this year (1989), the USFWS proposed threatened status for the pygmy sculpin because of proposed highway construction from Interstate 20 and possible chemical contamination of the groundwater from the near-by Anniston Army Depot. Hexavalent chromium and Trichloroethy¬ lene occur in strong concentrations in test wells at the army depot. SPECIAL CONCERN Notropis caeruleus Jordan blue shiner RANGE - Historically in Alabama, the blue shiner is known from the Cahaba River proper and several tributaries to the Coosa River including Big Wills Creek and its tributaries, Little River, Weogufka, Choccolocco, and Shoal creeks. The blue shiner has not been taken in the Big Wills Creek 110 Pierson watershed since 1958 and was last collected in the Cahaba system in 1971 (Ramsey and Pierson 1986) . STATUS - The Alabama Nongame Wildlife Program recently funded a study on the distribution and relative abundance of the blue shiner in Alabama (Pierson and Krotzer 1987) . No new populations were found, but fair to good populations were documented in Little River (Cherokee County) , Choccolocco Creek (Calhoun County) , and Weogufka Creek (Coosa County) . A range extension was documented in Choccolocco Creek about four miles downstream from the known lower distribution limit. COMMENTS - These three known Alabama populations should be carefully monitored and additional life history information would probably help us better understand the needs of this sensitive species. NoCurus munitus Suttkus and Taylor frecklebelly madtom RANGE - Alabama populations are known historically from the main channels of the Tombigbee, Alabama, and Cahaba rivers and two major tributaries to the upper Tombigbee. STATUS — The frecklebelly madtom has probably been eliminated from the main channels of the Tombigbee and Alabama Rivers in Alabama. Small populations may remain in the Sipsey and Buttahatchee Rivers (major tributaries to the upper Tombigbee system). Recently, we have collected this small catfish in lower numbers in the Cahaba River main channel between Centreville and Radford (Pierson et al. 1989). COMMENTS - Due to increases in habitat loss, a change in conservation status from special concern to threatened is probably appropriate at the state level. If the Tombigbee system population is lost, endangered status would be recommended. Major Tombigbee River tributaries in Alabama should be searched for populations of this sensitive species. Typhlich thys subterraneus Girard southern cavefish RANGE - In Alabama the cavefish is known from at least 25 caves in the Tennessee River drainage and in two caves in the Big Wills Creek watershed which is part of the Coosa River system (Ramsey 1986) . STATUS - While fairly widespread over north Alabama, most populations are very small and fecundity is extemely low (Ramsey 1986) . COMMENTS - No new information is available on the status of the southern cavefish. Ammocrypta asprella Jordan crystal darter RANGE - Historically, Alabama populations are known from large-river habitats in the Mobile Bay basin and the Conecuh River proper. Ramsey (1986) indicated that populations of this obligate riverine species have apparently been eliminated from the Coosa River system. Recent col- 111 Status of Alabama fishes lections in the Black Warrior River system by Mettee et al. (1989) did not document the crystal darter. R. D. Suttkus (personal communication) reports that he has not collected the crystal darter in the Alabama River system in recent years. STATUS - Since 1983 Ammocrypta asprella has been collected in the Cahaba River proper at nine stations below the Fall Line (Pierson et al. 1989). In the Winter and Spring of 1989 Alabama Power Company biologists have collected both larval and adult crystal darters from the lower Tallapoosa River main channel. COMMENTS - Due to these apparent stable populations in the Cahaba and Tallapoosa systems, special concern status as designated in Mount (1986) seems appropriate . Etheostoma ditrema Ramsey and Suttkus coldwater darter RANGE - The spring-dwelling form has good populations only in Coldwater Spring (Calhoun County) and Glencoe Spring (Etowah County) . A possibly derived stream-dwelling form is found in tributaries to Waxahatchee Creek (Shelby County) and two Coosa tributaries in Coosa County (Ramsey 1986). STATUS - The coldwater darter benefits from the cooperative agreement designed to protect the pygmy sculpin and the recent proposed threatened status for the pygmy sculpin. COMMENTS - A study should be undertaken to determine the relationships between the spring form and the possibly derived stream— dwelling form. Etheostoma tuscumbia Gilbert and Swain Tuscumbia darter RANGE - In Alabama this darter is limited to spring and spring run habitat in the Southern Bend of the Tennessee River drainage. The only Tennessee population has apparently been extirpated and a total of eight populations have been lost in Alabama (Ramsey 1986). STATUS - Recently, an excellent new population was found in a spring pond below the water supply for New Hope in the Mountain Fork Creek system of Madison County (Dave Etnier, personal communication). COMMENTS — Known populations should be watched closely because of the vulnerability of spring organisms, and the Tennessee River system should be searched for additional populations. POORLY KNOWN Scaphirhynchus sp. cf. platorynchus Alabama shovelnose sturgeon RANGE - This undescribed Mobile basin endemic is known only from main channel habitat in the Tombigbee, Alabama, lower Coosa, and lower Cahaba rivers. Prior to a recent survey by Burke and Ramsey, no specimens had been documented since 1977. 112 Pierson STATUS - Burke and Ramsey (1985) recently conducted a status survey of this sturgeon. They stated that only about 15 percent of the total historical range of the shovelnose sturgeon appears to be adequate for its existence. The Alabama shovelnose sturgeon has been documented as re¬ cently as 1985-1986 in the Cahaba and Alabama rivers. COMMENTS - Based on data from the recent status survey, this sturgeon should probably be given threatened status. The USFWS Endangered Species Office is planning to propose threatened status in the near future. Hybopsis monacha Cope spotfin chub RANGE - This species was probably once found throughout the Tennessee River and its major tributaries, but it has only been collected from two Alabama localities: Shoal Creek, Lauderdale County, 1884 and Little Bear Creek, Colbert County, 1937. STATUS - Since this species has not been documented from Alabama in 52 years, chances are good that the spotfin chub has been extirpated from the state . COMMENTS - A thorough search of the two historical sites in Alabama should be undertaken to determine this chub's status. Etheo stoma trlsella Bailey and Richards trispot darter RANGE - Historically, the trispot darter probably occurred in small - medium streams of the upper Coosa system in Alabama. STATUS - The last collections of this species were at the type locality in 1948 (Cherokee County) and from the Coosa River below Gadsden (1958) . COMMENTS - This species may no longer occur in Alabama. A status survey of this species in Alabama should be undertaken, concentrating on streams of the upper Coosa system near the type locality. Polyodon spathula Walbaum paddlefish RANGE - The paddlefish is known to occur in large-stream habitat of the Mobile and Tennessee river systems in Alabama. STATUS - In the last few years large, sexually mature females have been heavily harvested for their roe which brings a good price as a substitute for sturgeon roe. This development, coupled with a declining fishery prompted the Alabama Department of Conservation and Natural Resources to pass a law in 1988 to prevent the harvest of paddlefish in all public waters of Alabama (Bill Reeves, personal communication). COMMENTS - Alabama Department of Conservation and Natural Resoruces personnel indicate that a healthy year class (probably 1983 spawn) is coming along in the Alabama River system and should be reproductively capable in two or three more years. Additionally, higher than normal 113 Status of Alabama fishes spring and early summer rainfall should have produced a good 1989 year class . Cycleptus elongaCus LeSueur blue sucker RANGE - In Alabama the and blue sucker has historically occurred in the large streams of the Mobile and Tennessee drainages. In recent years suitable riverine habitat has declined, mainly because of impoundments. It is difficult to assess the status of this species because it usually inhabits the deepest water and most torrential current available. STATUS - Recently we have documented specimens from the Coosa and Talla¬ poosa main channels during early spring spawning movements. COMMENTS - A thorough field survey is needed to determine the status and range of the blue sucker in Alabama. Percina lenticula Richards and Knapp freckled darter RANGE — In Alabama the freckled darter is found in large— stream habitat in the Mobile basin. It frequents deep, fast waters around heavy instream cover, therefore, it is easily missed in conventional fish collections. STATUS - Recent records have been established from tributaries to the Tom- bigbee River, Cahaba River and its tributaries, the Tallapoosa River proper, and a single adult from the Coosa River proper below Jordan Dam. COMMENTS - A thorough distribution and life history study is needed to accurately assess the status of this elusive darter. Morone saxatilis Walbaum striped bass (Gulf Coast strain) RANGE — The striped bass historically made spawning runs into freshwaters of the Mobile bay system and other large coastal streams such as the Conecuh and Choctawhatchee rivers. STATUS - Impoundments on the Alabama and lower Tombigbee Rivers have blocked or hindered spring upstream spawning movements in the Mobile Bay drainage. Additionally, the State of Alabama Department of Conservation and Natural Resources have been stocking the Atlantic strain striped bass for years and more recently the hybrid striped bass x white bass on a put and take basis. There have been no positive records of natural reproduc¬ tion by the striped bass in many years. COMMENTS — According to the Alabama Department of Conservation and Natural Resources personnel, there may be no Mobile Bay strain of striped bass left. There is a cooperative effort to do some genetic work to compare the striped bass in the Appalachicola system with preserved specimens at various fish collections in the southeast. 114 Pierson LITERATURE CITED Boschung, Herbert, 1986.

Mount Professor Emeritus Department of Zoology and Wildlife Science Auburn University , AL 368A9 -5A1U INTRODUCTION The most recent attempt at a comprehensive assessment of the status of the amphibians and reptiles of Alabama was in 1983. Thirteen scientists participated in the effort, and their conclusions were published in 1986 (Mount, ed.). Of a total of 149 native, breeding distinctive species and subspecies, 39 were categorized as endangered, threatened, poorly known, or otherwise considered deserving of special concern. Of this collective assemblage, only 7 species subsequently received significant specific at¬ tention by researchers and/or governmental agencies. These are mentioned in the following discussion, along with other information pertaining to the status and welfare of the state's herpetofauna . RESEARCH EFFORTS Dusky gopher frog ( Rana areolata sevosa ) . Mark Bailey continues his investigations of this rare species. Although the dusky gopher frog, one of the many animals that live in gopher tortoise burrows, has been report¬ ed from 10 localities in Alabama, only four ponds, two each in Covington and Escambia counties, are now known to support breeding. Two of these are being adversely impacted by runoff from nearby dirt roads and another by cattle (Bailey 1989, 1990). Bailey's research has been funded in part by the Alabama Nongame Wildlife Program. Red Hills salamander ( Phaeognathus hubrichti) . This federally listed threatened species is known only from a small area of southern central Alabama. Dr. C. K. Dodd (1988) studied the species and concurred in earlier workers' reports that clear-cutting of its hardwood cove and ravine habitats reduces or eliminates populations of the salamander. He recommended purchase of some tracts of suitable habitat to enhance its chances of survival. Black Warrior waterdog ( Necturus sp.). This undescribed, "poorly known" aquatic salamander, known only from Alabama, has received research attention from Ray Ashton and Paul Moler. Publication of a formal de- ’This article was presented as an invited paper at a Symposium on the Status of Endangered Species in Alabama on 24 March 1989 at the annual meeting of the Alabama Academy of Science held at Birmingham- Southern College, Birmingham, Alabama. Some of the information it contains, however, has been obtained subsequently. 117 Mount scription, along with other results of their investigations, are forth¬ coming. Ashton's initial studies on this salamander were funded in part by the Alabama Nongame Wildlife Program. Flattened musk turtle ( Stemotherus depressus) . Dodd, et al. (1986, 1988) conducted an investigation of this species, now federally listed as threatened, in 1986. Although the study was designed primarily to assess the impacts of strip-mine runoff on the turtle, a wealth of other data on the species was collected as well. The study confirmed that runoff from strip mines does adversely impact the turtle, as does that from other activities that expose the soil to erosion. The flattened musk turtle occurs only in Alabama, in streams of the upper Black Warrior River basin. A recent "Problem Assessment Report," prepared by representatives of ten federal and state agencies and pub¬ lished by the U.S. Soil Conservation Service (1989), indicated that "a large number of streams" in the basin "are adversely impacted by pollutants from various sources." The report stated further that "Fishery resources and aquatic organisms within these streams are showing signs of stress and depletion." The implications with respect to the flattened must turtle are obvious. Alabama red-bellied turtle ( Pseudemys alabamamens is) . Now on the federal list of endangered species, the Alabama red-bellied turtle is endemic to Alabama and occurs only in the lower portion of the Mobile Bay drainage. Dr. James L. Dobie and representatives of the Alabama Depart¬ ment of Conservation and Natural Resources and the U.S. Fish and Wildlife Service continue their efforts to secure protection of the turtle's major nesting site, a beach- like area on an island in the Tensaw River. Most of the site is owned by the Coastal Land Trust, headquartered in Mobile. Several other turtles and some shore bird species also nest there. A recovery plan, prepared by Dr. Dobie and Fred Bagley (U.S. Fish and Wildlife Service, 1990) calls for additional research and conservation efforts, which, in order to be successful, will require the cooperation of the Coastal Land Trust. Authorities are hopeful that such cooperation is forthcoming. The Alabama red-bellied turtle was officially designated as the State Reptile of Alabama during the 1990 session of the legislature. Eastern indigo snake ( Drymarchon corais couperi) . This snake is federally listed as threatened. Dr. Dan Speake and his colleagues have conducted research on several aspects of the snake's ecology and life history, the most recent having been a study of the ecology of the juve¬ niles and gravid females in northern Florida using telemetry (Smith, 1987). Dr. Speake is also monitoring the results of successful efforts at re¬ establishing populations in Covington and Washington counties and is evaluating the results of several other re-stocking efforts in Alabama. 118 Status of Alabama amphibians and reptiles Recent field sightings, although lacking documentation, suggest that one or more native populations of indigo snakes may have escaped extirpation in Alabama. GENERAL OBSERVATIONS Aside from those on the aforementioned species and a few studies on small areas, most of the information on Alabama reptiles and amphibians obtained since 1986 is based on subjective impressions. Numerous con¬ versations with professional zoologists and with interested laymen, conjoined with my own observations, suggest the following with respect to some of the other species: 1. Most frogs and toads that were common or abundant in 1986 are faring reasonably well in areas where habitat is or appears to be suitable. Nothing has been added to our knowledge relative to the status of two species, rare in Alabama, the wood frog ( Rana sylvatica) and the Pine Barrens treefrog ( Hyla andersonii) . 2. Nothing has been added to our knowledge of the status of the various salamanders other than those mentioned previously. It can be safely assumed, however, that as habitats for the respec¬ tive species decline in abundance or quality, corresponding declines will occur in the salamander species requiring the habitats . 3. Among lizards, an apparent continuing decline in the six-lined racerunner ( Cnemidophorus sexlineaCus ) perhaps warrants "special concern" status for that species. Legless lizards ( Ophisaurus ventralis , 0. attenuatus , and 0. mimicus) are very likely at a historic low ebb. 4. Population densities of numerous snakes are declining over all or large portions of their ranges. Those that appear to be relatively stable are few and include some of the water snakes ( Nerodia spp.) and, notably, gray rat snakes ( Elaphe obsoleCa spiloides ) . Among those species that once were encountered fairly frequently, but are now becoming scarce over large areas of the range include corn snakes ( Elaphe guttata) , hognose snakes ( Heterodon simus and H . platyrhinos ) , coachwhips ( Masticophis flagellum) , queen snakes ( Regina septemvittata) , and mole snakes ( Lampropeltis calligaster rhombomaculata) . 5. Little has been added to our knowledge of the status of Alabama's fresh-water and estuarine turtles, except for those mentioned above. Casual observations suggest that those species capable of living in ponds and fresh water swamps are thriving, whereas those restricted to streams (ex. Graptemys spp.) may be declining, along with the Mississippi diamondback terrapin ( Malaclemys terrapin pileata) , a salt-marsh species. Commercial exploitation continues to be a problem of unknown magnitude for some species. 119 Mount 6. Atlantic loggerhead sea turtles ( Caretta caretta caretta) at¬ tempted to nest on Alabama's coast in 1987 for the first time in more than 15 years. At least two sets of hatchlings resulted from the attempts on Dauphin island and one set emerged at Gulf Shores. This marine turtle is federally listed as "Threatened." Protective measures taken by biologists with the Alabama Depart¬ ment of Conservation and Natural Resources doubtless contributed to the nesting successes. 7. Alligator ( Alligator mississippiensis) . Populations appear to be stable or increasing within the species' range in Alabama. The status of the alligator in Alabama (federal level) has been downgraded from "endangered" to "threatened due to similarity of appearance." In 1989, legislation was enacted to permit "alliga¬ tor farming" in the state. RECOMMENDATIONS Included in the above referenced 1983 publication edited by Mount, the section dealing with amphibians and reptiles contained, collectively, about 100 specific recommendations that would be helpful to those species considered endangered, threatened, "special concern," or "poorly known." Of those, approximately 74 have received little or no attention. Exem¬ plary among the latter was a plea for a state law or regulation pro¬ hibiting the introduction of gasoline or other toxic materials into the burrows of hibernating gopher tortoises. This destructive practice has been banned in Florida, but in Alabama such a prohibition is in effect only in Conecuh National Forest, by the U.S. Forest Service, and in Choctaw, Washington, and Mobile counties, where federal law protects the tortoise as a threatened species. A statewide ban on gassing tortoise burrows should be instituted. Several aquatic reptiles are believed to suffer as a result of their being used as targets by "plinkers." Currently, existing laws and regulations are inadequate to prevent this practice. A law or regulation that would prohibit the discharge of rifles into or over the public waters of Alabama is needed. Exemptions could be made, if justified, for hunting of certain game animals within season. Netting for fish in the fresh waters of Alabama is believed to result in the death of several species of aquatic turtles, including the endan¬ gered Alabama red-bellied turtle (U.S. Fish and Wildlife Service, 1990). An effort to prohibit the use of gill nets in the public fresh waters of Alabama during the 1989 legislative session was unsuccessful. Fresh water turtles, as well as several declining species of fish (e. g. , paddlefish, Polyodon spatula ) would probably benefit by a ban on gill nets, trammel nets, and hoop nets in our streams and reservoirs. Many of the recommended measures that have not been implemented deal with needs for research. Currently, mechanisms are available for federal funds to be used for research on birds, mammals, and fishes in the state through cooperative agreements between the Alabama Department of Conser- 120 ! Status of Alabama amphibians and reptiles vation and Natural Resources and the U.S. Fish and Wildlife Service. A cooperative agreement for federal funding for research on reptiles and amphibians is currently (March 1, 1990) non-existent, but could be negotiated under Section 6 of the Endangered Species Act. It is recom¬ mended that the Department of Conservation and Natural Resources proceed forthwith to secure such an agreement. An increased interest in use of herbicides, including aerial appli¬ cations, in commercial forestry is a cause for concern. As nearly as I can determine, virtually no information is available on the impact of herbicides on the herpetofauna of our forestlands. Information on their impacts on small, isolated wetland communities is also very limited. These wetlands, often referred to as "class 1 and class 2 wetlands," are often overlooked because of their ephemeral nature but are essential to the survival of several amphibians that breed in them. Research on direct and indirect impacts of herbicides is badly needed. Finally, a realistic re-assessment of the status of the state's reptiles and amphibians, using the best available knowledge, should be undertaken. A recent change (January, 1990) in a D.C.N.R. regulation leaves the vast majority of the species with no protection whatsoever. The only species now protected are those that were categorized in 1983 (in Mount, ed. , 1986) as endangered, threatened, or "special concern," along with common snapping turtles ( Chelydra serpentina) and softshell turtles ( Trionyx spp.) under eight inches in length. A good case can be made for placing all "poorly known" species, along with those that are believed to be in a state of continuing decline, under the "special concern" category. Presumably, such species would then become eligible as candidates for protection by the state. LITERATURE CITED Bailey, Mark A. 1989.

Yunjo Soh and Marie W. Wooten, Dept, of Zoology/Wildlife, Auburn Univ. , Auburn, AL 36849 A protein kinase which displayed activity in the presence of Mg2+/Mn2+ was purified by a series of column chromatographic steps from HL60 cells. Sequential column chromatography on DEAE-Sepharose, Protamine agarose, hydroxylapatite and Toyopearl HW55 yeilded an enzyme which was >95% homogenous as judged by SDS-PAGE silver stain. Kinetic assays conducted in the presence of various substrates demonstrated a preference for protamine. In the presence of micromolar amounts of Ca2+, protamine kinase activity was inhibited. Lipid activators, phosphatidylserine and diolein did not activate the kinase. Protamine kinase has an apparent molecular weight of 120kDA, with an apparent dimeric structure. Studies are in progress to examine the role of this kinase system during HL60 differentiation. BIOTECHNOLOGY OF ALGAE. Mahasin G. Tadros, Beverly Joseph and Woodrow Smith, Department of Biology, Alabama A&M University, Normal, AL 35762. Algae are known to respond to alterations in environmental conditions and nutrient shortage by adjustments in physiological adaptations. Marine diatoms (Bacillariophyceae) and Cyanobacteria (Cyanophyceae) were characterized in batch cultures under various growth conditions: temperature, light irradiations, and nutrient concentrations. Diatoms produced high lipids while cyanobacteria produced high carbohydrates, when stressed. The results indicated that the partioning of the assimalatory products were manipulated by varying the environmental growth conditions. 123 Abstracts CRYPTOSPORIDIUM BAILEYI : CLINICOPATHOLOGIC EFFECTS OF INFECTIONS IN BROILER CHICKENS. B. L. BLAGBURN. J. F. DAVIS, J. J. GIAMBRONE, D. S. LINDSAY and J. S. SPANO, Departments of Pathobiology and Poultry Science, Auburn University, AL 36849. One hundred thirty two, one-day-old commercial broilers were randomly allocated into 3 groups of 44 (22 male, 22 female) birds each. Group I birds were controls. Groups 2 birds were each given 500,000 C. baileyi oocysts intratracheally (IT). Group 3 birds received the same number of oocysts per os (PO). Birds were inoculated on day 7. Birds were maintained in electrically heated Petersime wire batteries (controls in a separate room), and fed a standard starter ration and water, ad libitum. Birds were weighed weekly through day 42. Four birds from each group were sacrificed on days 1, 4, 8, 11, 15, 18, 22, 25, 29, 36 and 43 and a 2-3 cc heparinized sample of oxygenated blood was collected from the left ventricle. Blood or serum were immediately analyzed for pH, pOz, pCOz, HC03', C02, Na+, K+, Cl" and anion gap values. Random fecal samples were taken for oocyst enumeration on days 6, 8, 11, 13, 15, 18, 20, 23, and 25. Blood or serum values were compared using ANOVA and Duncan’s Multiple Range Test. Birds given C. baileyi IT developed respiratory disease and weight depression similar to those previosly described. Birds inoculated PO did not demonstrate clinical signs. Oocyst excretion dynamics were similar to previous studies. Clinicopathologic results indicated the p02 (deer.), pC02 (incr.), HC03 (incr.) and COz (incr.) values were altered only in IT inoculated birds, and correlated with acute respiratory disease. No significant alterations in blood gas or serum electrolyte values were observed in PO inoculated birds. USE OF RIVULUS FOR SCIENTIFIC STUDIES. John H. Grover, John M. Grizzle, and Sarah J. Grover, Dept, of Fisheries and Allied Aqua¬ cultures, Auburn University, Auburn, AL 36849. The small drab fish known as Rivulus may provide the key to important work in toxicology and tumor research. These fish are more sensitive to cancer-causing chemicals than terrestial vertebrates. They also are unique among fish because they have air respiration capability and are self-fertile hermaphrodites, thus having the ability to essentially "clone" themselves while living in a stagnant dish of water. This paper discusses what is known about their biology, laboratory care, and shares some of our experience working with this animal. Potential uses of rivulus in other scientific research and teaching are also discussed. 124 Abstracts SEX STEROIDS MAY REGULATE SPERMATOGENESIS IN THE SEA STAR ASTERIAS VULGARIS . Gene A. Hines and S.A. Watts, Dept, of Biology, U.A.B. , Birmingham, AL 35294. S.A. Sower and C.W. Walker, Dept, of Zoology, University of New Hampshire, Durham, NH 03824. Levels of the sex steroids estradiol, testosterone and progesterone in testes were determined via radioimmunoassay throughout the 1988-89 annual reproductive cycle of A. vulgaris . During the summer months testes contained stem spermatogonia, residual spermatozoa and phagocytic somatic cells and appeared metabolically inactive. Sex steroid levels were lowest during this aspermatogenic period. In the early fall, spermatogonia began to divide mitotically and testicular mass began to increase. In late fall, spermatogonia differentiated to form columns containing primary spermatocytes in various stages of meiosis I. Estradiol levels increased greatly at the onset of spermatogonial mitoses (0.42 ng/g), followed by a transient peak in testosterone (2.36 ng/g) ca. 1 month later during spermatocyte column formation. Progesterone levels increased to a maximum of 4.98 ng/g ca. 1 month following the peak in testosterone levels, and were coincident with the initiation of spermiogenesis . In the winter, spermatozoa were produced and stored in the testicular lumen and steroid levels remained low. Transient peaks of testosterone and progesterone occurred in the early spring. In the late spring spawning occurred and all steroid levels decreased. Similar seasonal variations in the levels of these steroids in ovaries and in male and female pyloric caeca occurred during the annual reproductive cycle. We hypothesize that transient increases in the levels of sex steroids at the onset of gametogenesis may serve as intrinsic modulators of spermatogonial proliferation and spermatocyte differentiation.

Bone, Animal Parasite Research Laboratory, ARS, USDA, Auburn, AL 36830. The lectin, Limulus polyphemus agglutinin (LPA) , was lethal to eggs of the ruminant nematode Trichostrongylus colubrif ormis . Eleven other lectins had no effect. Fluorescein-labelled LPA bound to the nematode egg, but this binding was inhibited by pretreatment of the eggs with sialic acid or sialidase. Treatment of nematode eggs with sialic acid after LPA exposure caused increased ovicidal activity. Sialic acid only had no effect. Sialidase had no influence on eggs, but enhanced the lethality of LPA. Sialic acid or similar carbo¬ hydrates may contribute to some critical regulatory process in the nematode eggshell. 125 Abstracts DEMONSTRATION OF ANTIGENIC VARIATION IN A STRAIN OF TETRAHYMENA PYRIFORMIS BY USE OF A MONOCLONAL ANTIBODY. JL. Estridge and C. A. Sundermann, Dept. Zoology & Wildlife Sciences, Auburn University, AL 36849. Antigenic variation in surface membranes of protozoa has been studied for many years. This paper reports a preliminary investigation of antigenic variation in the surface membrane of the amicronucleate ciliate Tetrahvmena pyriformis (ATCC 30005) using immunohistochemical techniques. Monoclonal antibodies (MAb) against T . pyriformis ciliary membrane proteins were generated using standard methods. Using immunoperoxidase staining, MAb 6F10, which has been shown by Western blot to react with a 15-18 kD membrane protein, was observed to stain the stock culture heterogeneously, with positive cells showing deeply stained cilia and cell membrane, and other cells being negative. Both positive and negative clones were established. Some clones which were initially positive- staining showed heterogeneous staining when tested with the same MAb over time; the same situation occurred with clones initially negative. Percent positive cells was higher in clones grown at RT (21-22 C) than in those grown at 28 C. Preliminary testing of clones grown in five different growth media showed some differences in the percents of positive staining cells. The variation in staining of the clones suggests that more than one antigenic type is present in the stock culture, and that the antigenic expression can be influenced by changes in temperature and growth media.

Lishak, Dept, of Zoology and Wildlife Sciences, Auburn, AL 36849. The mating system of the eastern gray squirrel is best described as scramble competition polygyny in which many males chase and ultimately mate with a female squirrel in estrous. The stimuli that allow males to detect estrous females and those that are thought to enhance the cohesiveness of aggregations of males were studied by: 1) presenting squirrels with urine from two hand-raised female squirrels in estrous, and 2) the playing of previously recorded mating calls. Focal animal sampling revealed that when urine was presented alone or in combination with the playing of mating calls, males investigated the stimuli but patterns of locomotion associated with mating chases were not observed. The playback of mating calls resulted in approach and investigatory behaviors but aggregations of males did not form. 126 Abstracts GAMETOGENESIS AND EARLY OOCYST FORMATION IN THE MOUSE COCCIDIAN EIMERIA VERMIFORMIS (APICOMPLEXA) . Stephanie Stafford and C.A. Sundermann, Dept, of Zoology, Auburn University, Auburn, AL 36849 The development of gamonts and oocysts of Eimeria vermif ormis has not yet been described. Thus, the purpose of this study was to investigate gametogenesis and the development of young oocysts using histological/light microscopical and electron microscopical preparations of parasites grown in vivo. Mice were inoculated orally with 5000 oocysts of E. vermiformis and sacrificed at 7-12 days post inoculation (DPI) . At 7 DPI young macrogamonts were seen in the jejunum. Living specimens were subspherical to ovoid and had a mean length of 19.5 pm and a mean width of 15.8 pm. Microgamonts were first seen at 8 DPI and had a mean length of 15.5 um and a mean width of 13.7 pm. In histological sections 62% of 200 gamonts were macrogamonts and 38% were microgamonts. Thick-walled oocysts were seen at 9-12 DPI. TEM revealed that microgamonts (at 8 DPI) had electron-dense nuclei which emerged from the gamonts, each nucleus was followed by a single elongated mitochondrion with tubular cristae. Mature microgametes possessed two flagella that appeared to be associated with basal body. Ultrastructural studies of macrogamonts revealed the presence of two types of wall forming bodies (WF) . Type I (WF-I) were spheroid, electron-dense and measured 1.27 pm in diameter. Type II (WF-2) appeared first in young macrogamonts and were spheroid, spongy in appearance and measured 1.45 pm in diameter. As oocyst development proceeded, WF-l's disaggregated into smaller particles at the periphery of the parasite and fused to form a membrane bound electron-dense outer layer of the oocyst wall. Wf-2's became more labyrinthine in appearance and moved into the intermembranous space beneath the developing outer layer. Biochemical Sytematics of the Fundulus grandis-F. heteroclitus species complex (Pisces:Cyprinodontidae). C.F. Duggins, Dept, of Biology, Univ. of South Carolina, Columbia, South Carolina 29208, K. Relyea, Dept, of Biology, Univ. of Montevallo, Montevallo, Alabama 35115, and A. A. Karlin, Dept, of Biology, Univ. of Arkansas, Little Rock, Arkansas 77204. Fundulus grandis ranges from NE Florida to Mexico along the Atlantic and Gulf of Mexico coasts, and disjunctly in Cuba where it has been recognized as £4 saguanus. Relyea (1983) suggested that, on the basis of morphological traits, Florida Keys populations should be included in F. g. saguanus. Our studies of isozyme variation show no difference in isozyme allele frequencies between Florida Keys populations and other F. grandis. Recognition of subspecies is questioned, but Cuban material remains to be examined. Fundulus grandis and F. heteroclitus are distinct at a specific level based on isozyme analysis. 127 Abstracts REVERSION OF HEMOGLOBIN PROPORTIONS TOWARD NEWBORN VALUES BY TWO CHEMOTHERAPEUTIC AGENTS IS TOTALLY BLOCKED BY ASPIRIN. Veronica D. Boswell, Habiba A. Dow la and Mukul C. Datta, Department of Chemistry, Tuskegee University, AL 36088. Studies with anemic baboons and monkeys have found augmentation of Hb F production when treated with S-phase specific agents. This study was carried out to determine whether 5-azacytidine (AZA) that induces Hb F synthesis in humans and primates can induce newborn like Hb proportions in anemic adult rats. If so, then to explore the possi¬ ble involvement of other factor(s) and to compare the effect of AZA with hydroxyurea (HU) which also activates Hb F synthesis in adults. Mild anemia was developed in normal adult Sprague-Dawley or Wistar rats. A fixed dose of AZA (1.5 mg/500 g) or HU (75 mg/500 g) was ad¬ ministered each time intravenously in each of such anemic rats for al¬ together 35 times covering a span of b9 days. Anemia of moderate de¬ gree was maintained by bleeding once a week during the entire drug treatment. Blood samples drawn on every Friday were analysed by ion- exchange chromatography. A significant increasing pattern was measured for Hb components I, II and IV in red cells of the AZA or HU treated rats compared to the anemic controls (p < O.Ol), a situation analogous to that observed between normal adult and newborn samples. However, acetylsalicylic acid (ASA) intake at a dose level of 20 mg/ day/500 g along with AZA or HU administration totally blocked the changeover of Hb components toward newborn proportions. Based on the clinical trials of these two drugs , several experts proposed that hypomethylation of DNA is not necessary for increased Hb F production as a sole mechanism. However, since ASA is known to inhibit prostaglandin synthesis, our re¬ sults reveal the importance of concurrent prostaglandin synthesis as a common mechanism for the expression of both HU and AZA mediated changes AVIAN NESTING HABITAT - CRITICAL FOR COASTAL ALABAMA. John L Dindo. Dauphin Island Sea Lab, Dauphin Island, AL 36528. Ken R. Marion, University of Alabama at Birmingham, Birmingham, AL 35294 and Dan Holliman, Birmingham Southern University, Birmingham, AL 35254. Increase population and industrial growth has caused the loss of some critical nesting sites along Dauphin Island, Sand Island and the coastal mainland. Sand Island and Dauphin Island have been prime breeding sites of Least Terns, Sterna albifrons, Sandwich Terns, Sterna sandvicensis, Gull- Billed Terns, Gelochelidon nilotica and the Black Skimmer, Rynchops niger. Increased public use of these areas as well as unauthorized vehicular traffic has forced these species out of these nesting sites. Little Dauphin Island, part of the Bon Secour National Wildlife Refuge, and Cat Island remain as nigh density nesting sites for numerous coastal species. 128 Abstracts REPRODUCTIVE PERIODICITY AND GAMETOGENESIS OF THE IRREGULAR SEA URCHIN CLYPEASTER RAVENELII FROM THE GULF OF MEXICO. Jeffrey D. Vernon and James B. McClintock, University of Alabama at Birmingham, Birmingham, Alabama 35294 and Thomas S. Hopkins, Dauphin Island Sea Laboratory, Dauphin Island, Alabama 36528. Clypeaster ravenelii is a common offshore irregular sea urchin with a distribution ranging from North Carolina southward to the Yucatan Peninsula in the Gulf of Mexico. Although population densities are high, little is known about the biology of this species. Periodic collections of Clypeaster ravenelii were taken from November 1988 to February 1990 using an Otter trawl on a fine¬ grained substrata 25 miles off the coast of Pensacola, Florida. Individuals were collected from a depth of 90 meters. Reproductive condition was determined by gonad indices (wet weight of the gonad divided by the wet weight of the individual X 100) and histological examinations of the testes and ovaries of ten individuals on each sampling date. Gonad indices were low in spring and summer, th en rose slightly in the late fall, and peaked in the late winter. Ripe gonads, as indicated by oozing gametes, high gonad indices and testicular and ovarian lumens filled with spermatozoa and oocytes, were observed in February during both 1989 and 1990. Clypeaster ravenelii has an annual reproductive cycle and, in contrast to most echinoids which are spring spawners, releases its gametes in the winter.

Thermal tolerance was studied in a lotic population of freshwater shrimp (Palaemonetes kadiakensis) in Mobile Co., Alabama. Shrimp were acclimated in the laboratory Jior a minimum Qof 2 weeks at four constant temperature regimes (20 C, 24 C, 28 C, & 32 C) . Specimens (N = 85) manifested several responses to thermal stress: initial disorientation, complete disorientation, onset of tail fold, and loss of movement. Values for all of these parameters were directly related to the temperature of acclimation. Initial disorientation was assumed to represent the critical thermal maximum (CTM) . Beginning with shrimp acclimated at 20 C, respective values for initial disorientation were 33°C, 36 C, 38 C, and 39 C. Data are compared with those from lentic and lotic congeneric populations from Michigan and South Carolina. 129 Abstracts THE DUSKY GOPHER FROG IN ALABAMA. Mark A. Bailey, Alabama Natural Heritage Program, Department of Conservation and Natural Resources, Montgomery, AL 36130. Cynthia Ragland, USDA Forest Service, Route 5, Box 157, Andalusia, AL 36420. The dusky gopher frog (Ranidae: Rana areolata sevosa ) is one of Alabama’s rarest and most poorly known amphibians. Although reported from 11 locations in six counties (Baldwin, Barbour, Covington, Escambia, Mobile, Shelby), only six extant breeding populations are known: two in Escambia and four in Covington County. Although additional populations almost certainly exist, they are thought to be exceedingly scarce. Rangewide (LA, MS, GA, FL and AL), fewer than 20 extant populations of this subspecies are known. A survey, funded by the U.S. Forest Service, is being conducted by the Alabama Natural Heritage Program on the Conecuh National Forest to determine periods of breeding activity, distribution, and habitat. Gopher frogs typically breed in ephemeral ponds during the months of January, February, and March, but breeding occurred at one Covington County pond in late September of both 1988 and 1989. An Escambia County population was occupied by at least 269 adults during the 1986 winter breeding season. In Alabama, documented declines in gopher frog populations have resulted from road construction through a breeding site and introduction of fish (Centrarchidae) to a breeding pond. Additional threats include conversion of natural sandhill habitat to commercial pine stands, siltation of breeding ponds from adjacent roads and fields, and numerous factors contributing to the continued decline of the gopher tortoise ( Gopherus polyphemus), in whose burrows gopher frogs take shelter and feed. Needed to ensure the long-term survival of the dusky gopher frog in Alabama are: 1) protection of breeding sites and enhancement of gopher tortoise habitat on adjacent uplands, 2) surveys for new populations, and 3) further research into home range, larval ecology, and population genetics. COCCIDIOSIS IN GOATS IN THE SOUTHEAST: ITS IMPORTANCE IN PRODUCTION. John C. Frandsen, USDA Animal Parasite Research Laboratory, ARS, Auburn, AL 36831-0952. A survey of 103 goat producers in the southeastern United States conducted in the autumn of 1989 revealed that 63% perceived coccidiosis to be a major problem in production. Based on diagnoses by their veterinarians, 29% of these producers rated coccidiosis the most important disease in their herds. Intestinal worms and other parasites, caprine arthritis & encephalitis (CAE), abscesses, and pinkeye were considered their major herd health problem by 28, 8, 6 and 4% of the producers, respectively, again based on veterinary diagnoses. Coccidiosis occurred primarily in young kids, in spring and summer, though about 1 producer in 20 reported its occurrence in adults. The major effects of the disease were unthriftiness and failure to gain, but 30% of the producers reported mortality in kids. Amprolium was the most frequently used anticoccidial drug, followed by the various sulfonamides, alone and in combination. Decoquinate, lasalocid and Tribrissen® were used by less than 3% of these producers. The disparity between the percentage of producers perceiving coccidiosis as a major problem in goat production (63) and the percentage experiencing it as a major problem in their herds (29) is intriguing, and may indicate that the reputation of the disease is inflated. 130 Abstracts ELECTROPHORETIC ISOZYMES OF ADENOSINE DEAMINASE (AD) AND NUCLEOSIDE PHOSPHORYLASE (NP) IN NEONATAL, ADULT AND DIABETIC RATS. Joni L. Justice and Ronald L. Jenkins, Dept, of Bioloqy, Samford University, Birmingham, AL 35229. Previous studies of blood flow rates and total purine nucleotide levels in neonatal and diabetic rats have suggested that purine cata¬ bolic enzymes may be altered from that of the adult. In this study, heart, liver and gastrocnemius muscle from adults, streptozotocin dia¬ betic and 1 day old neonatal rats were homogenized in 50mM Tris, 50mM KCl , 1% Triton X-100, and 2mM b-mercaptoethanol and centrifuqed at 10,000 xq for 20 minutes. Isozymes of NP and AD in the supernates were separated by agarose electrophoresis and visualized with tetrazolium staining (Harris and Hopkinson. Handbook of Enzyme El ectrophoresis in Human Genetics, 1976). Percentages of each isozyme were quantitated by densi tometric scans. Total NP and AD activities in tissue fractions were quantitated colorimetrical ly using calibrated tetrazolium methods In neonatal muscle and heart, total NP activity was significantly ele¬ vated as compared to adult rats, while AD activity was significantly decreased in liver. The different isozymes of neonatal NP dramatically shifted toward anodal forms in muscle and heart, but toward cathodal forms in liver. The neonatal isozymes of AD were more anodal as com¬ pared to adult hearts. After 4 weeks of diabetes, adult rats had signi¬ ficantly elevated blood glucose levels (403+64 mg%) above controls (122+24 mg%). NP activity was significantly increased in muscle and heart, while AD activity was elevated only in heart. Isozymes of dia¬ betic rat NP shifted anodal ly in muscle and heart, but cathodal ly in liver as compared to controls. All cathodal isozymes of AD were lost in diabetic tissues, with a subsequent increase in anodal isozymes. ONTOGENETIC CHANGES IN THE DIEL ACTIVITY PATTERN OF THE GREENSIDE DARTER, ETHEOSTOMA BLENNI OOIDES . Robert Stiles, Dept, of Biology, Samford Univ. , Birmingham, AL 35229. Larry Greenburg, Dept, of Limnology, LUND, Sweden. A study of the diel activity pattern of the greenside darter (Etheostoma blennioides) was conducted in the Little River of eastern Tennessee during the Summer of 1988. Fish were collected over 24 hour periods using a handnet, while snorkeling. During 15-16 July and 25-26 August four day and two night collections were carried out, with additional collections at dawn and dusk. The standard lengths of day-captured and night- captured fish were compared using One-Way ANOV. Night- captured fish were larger and the difference was significant at the P< 0.0001 level. Analysis of stomach contents revealed that the large fish taken at night were actively feeding. Questions are raised concerning the adaptive value of switching activity patterns and the sensory systems used in nocturnal foraging. 131 Abstracts A COMPARATIVE STUDY ON THE POPULATION DYNAMICS OF THE BLUE CRABS CALUNECTES SIMMS AND C. SAPIDUS IN ESTUARINE ENVIRONMENTS OF THE GULF OF MEXICO. Pan-wen Hsueh, James B. McClintock. Dept, of Biology, University of Alabama at Birmingham, Birmingham, AL 35294. Tom S. Hopkins, Dauphin Island Sea Laboratory, Dauphin Island, AL 36528. Monthly samples were taken from three study sites in the greater Mobile Bay area, Alabama, using either an Otter Trawl (offshore) or a Beach Seine (inshore). Study sites were chosen to represent high, intermediate, and low salinity estuarine habitats. Field observations indicate that Callinectes similis co-occurs with C. sapidus in estuarine waters. However, C. similis dominates numerically at lower estuarine high and intermediate salinity sites, whereas C. sapidus is more abundant at an upper estuarine low salinity site. Juvenile C. similis recruit into both open-bay soft-bottom and salt marsh habitats, while juvenile C. sapidus recruit into salt marsh and grassbed habitats. C. similis in salt marsh habitats were never found greater than 3-cm in carapace width, indicating that young and adult crabs either migrate or are eliminated by predators. Subadult females of C. similis were abundant in the fall at open-bay sites, suggesting that mating may occur in the subsequent spring or summer, which is similar to the mating season of C. sapidus. In both species, males numerically dominate these estuarine populations.

James L. Dobie, Dept, of Zoology and Wildlife Science, Auburn Univ., AL 37849-5414. The Alabama red-bellied turtle, Pseudemys alabamensis, was listed as an endangered species by the U. S. Fish and Wildlife Service in 1987 and a recovery plan for the species has been prepared. The ultimate goal of the recovery plan is to provide for reclassification from endangered to threatened status. The species has declined over the last several decades and could become extinct if adequate conservation measures are not taken. The turtle was officially designated the State Reptile of Alabama during the 1990 legislative session. Factors contributing to the decline have been: (1) predation by humans, hogs, fish crows, imported fire ants, and alligators; (2) decreases in the amount of aquatic vegetation on which the species depends for food, cover, and basking; (3) trapping for food and for the pet trade; and (4) death by drowning in nets. Studies are needed on life history and ecology, and conservation measures should be instituted to protect the turtle's habitats. 132 Abstracts ACETYLATION OF HISTONES IN THE TESTES OF THE SEA STAR ASTERIAS VULGARIS . Sara K. Hecker, Carl B. Massey and Stephen A. Watts, Dept, of Biology, Univ. of Ala., Birmingham, AL 35294. Asterias vulgaris were collected in the fall during the annual reproductive cycle at the onset of spermatogenesis. Subsamples of A. vulgaris testes were incubated in the presence of l^C-acetate and n-butyric acid for two hours at 15°C in an attempt to measure the acetylation of histone proteins in germinal cells. The tissue was placed in liquid nitrogen to stop the reaction and stored frozen at -70°C. Histone proteins were acid-extracted from the frozen tissue, electrophoresed on an acetic acid-urea polyacrylamide gel (5% acetic acid-2.5 M urea-15% acrylamide), and stained with Coomassie blue for identification of specific histone isotypes. Stained gels were scanned with an LKB densitometer to determine Rf and relative protein content of the various bands of histone proteins. Gel slices representing histone protein variants were removed and dissolved in 307» peroxide. Radioactivity was determined by scintillation counting. Results indi¬ cated that slow migrating variants of H4 represent several multiply- acetylated H4 histones, the distance of migration being inversely proportional to the amount of incorporated acetate. Similar multiply- acetylated variants were observed in H3 . Acetylated variants of the nucleosomal histones H2A and H2B were not observed. These data suggest that H4 , H3-specific acetyltransferase( s) may be active during spermatogenesis. H4 and H3 are considered to contain the primary sites of DNA attachment to the nucleosome. Histone acetylations would result in decreased binding affinity for DNA allowing specific decondensation of chromatin and enhancing processes related to spermatogonial replication and transcription. ENDANGERED PLANT SPECIES OF COASTAL ALABAMA. Michel G. Lelong, Dept, of Biological Sciences, University of South Alabama, Mobile, AL 36688. Approximately 310 species of endangered, threatened and Special Concern plants occur in Alabama. Of these, 115 species grow in the Coastal Plain, including 66 in coastal Alabama. Over 40% of rare coastal plant species grow in Pine-oak savannas and bogs, includings Sarracenia rubra, S . rubra ssp. alabamensis , S. psittacina, Pinguicula planifolia, Pinguicula primulif lora , Andropogon arctatus, Panicum nudicaule and Lindera subcoriacea. Nearly 35% of rare coastal plant species occur in swamps, marshes and aquatic habitats, among them Lilium iridollae , Sium f loridanum, Ilex amelanchier , Epidendrum conopseum, Lilaeopsis caroliniana, Triglochin striatum, Myriophyllum laxum , and Potamogeton robbinsii . Less than 23% of rare coastal species occur in mesic or dry habitats, among them Rhododendron prunif olium, Oenothera grandif lora, Sagere t ia minut if lora , Polygonella macrophylla, and Polanisia tenuifolia . Efforts should continue to be made to preserve sites in coastal Alabama in which those rare plants grow, particularly in pine savannas, bogs and other wetlands . 133 Abstracts WHALES AND DOLPHINS OFFSHORE OF ALABAMA. Keith Mullin, Ren Lohoefener, Wayne Hoggard, Carolyn Rogers and Carol Roden, National Marine Fisheries Service, P.0. Drawer 1207, Pascagoula, MS 39568. Brian Taggart, Office of NOAA Aircraft Operations Center, P.O. Box 020197, Miami, FL 33102. Based on aerial surveys we have conducted and a review of literature on cetacean sightings and strandings , of the 76 cetacean species which occur world-wide, we estimated at least 20 have occurred offshore of Alabama (within 300 km of the coast). Four of these are whales (sperm, fin, sei, humpback) listed as endangered under the Endangered Species Act. All whales and dolphins in U.S. waters are protected by the Marine Mammal Protection Act. In shallow continental shelf waters (less than 200 m) , the bottlenose dolphin is the most common cetacean. Spotted dolphins also occur but are much less common. Other species are rare. The shelf waters have been well studied compared to the continental slope waters (greater than 200 m) . In the first study of its kind in the Gulf of Mexico, from July - November 1989, we conducted aerial surveys of continental slope waters in DeSoto Canyon, the Mississippi River Cliff and Mississippi Canyon. We made 119 sightings of cetacean herds with the following frequencies: sperm whales, 23%; Atlantic or pantropical spotted dolphins, 19%; dwarf or pygmy sperm whales, 13%; bottlenose dolphins, 13%; Risso's dolphins, 10%; common dolphins, 8%; Mesoplodon spp. , 4%; short-finned pilot whales, 3%; Cuvier's beaked whale, long- or short-snouted spinner dolphins, striped dolphins, false killer whales, and a fin whale (total 7%). Killer whales, Bryde's whale and rough¬ toothed dolphins have also occurred offshore of Alabama. POPULATION DYNAMICS AND REPRODUCTION OF THE BLUE CRAB CALLINECTES SAPIDUS IN AN ALABAMA ESTUARY. James B. McC 1 intock . Ken Marion and Pan Wen Hsueh, Dept, of Biology, Univ. of Alabama at Birmingham, Birmingham, AL 35294. Studies were initiated in May 1989 at Weeks Bay National Estuarine Reserve, located on the eastern side of Mobile Bay. Three sites, indicative of the estuary mouth, mid-bay and river inflow, were sampled monthly using an Otter Trawl. Triplicate 300 m tows were performed at each site and abundance, size, sex, molt condition and gonad index determined. Crabs were generally small and most abundant in the estuary in early summer, particularly at mid-bay and river mouth sites. Males greatly outnumbered females at these two sites during the summer, while females became more common than males during the winter. Molting was most common in the summer at mid-bay and bay-mouth sites. Recruitment was low and constant with small pulsations in August and January. No berried female crabs were caught, indicating that mature females probably migrate out of the estuary to spawn their larvae into higher salinity water at the mouth of Mobile Bay. Gonad indices were variable, but higher in the summer than the winter. This study is supported by a grant from NOAA. 134 Abstracts HYPOOSMOTIC INDUCTION OF ORNITHINE DECARBOXYLASE ACTIVITY IN THE BRINE SHRIMP ARTEMIA . Stephen A. Watts and Frederica White, Dept, of Biology, Univ. of Ala., Birmingham, AL 35294. Ar temia can tolerate a wide range of salinities and are often found in many salt and brine lakes. Long-term (several days) osmotic and ionic regulation is accomplished by changes in the levels of sodium and chloride ions and is controlled principally by the activity of Na+K+ATPase. Dried Artemia cysts were hydrated at 4°C and 32 ppt salinity overnight. Hydrated cysts were incubated at 28°C and 32 ppt for 25 hours. Batch samples of nauplii were removed and placed in 5 , 15, 32 (control), 40 or 50 ppt salinity. ODC activity was determined at time 0, 2, 4, 6 and 24 hours. Exposure of larvae to hypoosmotic conditions increased levels of ODC activity within 2 hr, resulting in a 60% and 460% increase in activity at 15 and 5 ppt, respectively. Activity decreased significantly by 4 hours but remained above that of the 32 ppt control throughout the 24 hr exposure period. Increases in ODC activities were reflected by significant increases in the levels of the polyamine products, putrescine and spermidine. Exposure of larvae to hyperosmotic conditions resulted in a 30% depression in ODC activity at 40 and 50 ppt, however, ODC activity returned to control levels within 4 hr in those exposed to 40 ppt, and within 6 hr in those exposed to 50 ppt. Polyamine levels decreased in proportion to decreased ODC activity. Changes in ODC activity and polyamine preceded acclimatory changes in whole animal wet weight. These data suggest that modulation of ODC activity and subsequent polyamines synthesis, degradation and/or transport are mechanistically related to short-term regulation of osmotic and ionic balance.

In 1978 Love Canal, was the first hazardous waste site to be declared a "federal emergency disaster area" by the President of the United States. The property had been used for disposal of toxic wastes by Hooker Chemical Company prior to its donating the land to the Niagara Falls Board of Education. Currently many United States industries, even those which employ the latest in high-tech manufacturing methods, still dispose of their toxic wastes by primitive methods. The 1980 Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and its 1986 amendments (SARA) were enacted by Congress as a federal response to the public health and environmental hazards which result from improper use and disposal of hazardous substances. The purpose of CERCLA is twofold: 1) to abate release of hazardous substances and 2) to provide both a long-term and short-term response to spills or leaks from hazardous waste sites. In 1988 the State of Alabama enacted the Alabama Hazardous Substance Cleanup Fund, which parallels CERCLA and the SARA amendments in some important aspects but is broader in several defenses which may be utilized by responsible parties to excuse them from liability. 135 Abstracts CONSERVATION PROGRAM FOR SEA TURTLES IN THE SOUTHEASTERN CONTINENTAL UNITED STATES. Earl E. Possardt, (U.S. Fish and Wildlife Service, 3100 University Boulevard South, Jacksonville, Florida 32216) The southeastern United States provides nesting habitat for a major loggerhead (Caretta caretta) rookery. Estimates of up to 50,000 nests deposited annually suggest that at least one-fourth of the world's loggerhead population may nest here. The green turtle ( Chelonia mydas) and leatherback (Dermochelvs coriacea) also nest but far less abundantly. The hawksbill (Eretmochelvs imbricata) is a rare nester. The Kemp's ridley (Lepidochelys kempi) frequents coastal waters. Coastal development, sea walls, riprap, and exotic trees degrade nesting habitat. Incidental capture from commercial fisheries drowns sea turtles; artificial lights disorient hatchlings and can cause high mortality; and predators and erosion can cause excessive nest loss in some localities. Governmental and private organizations carry out a variety of nest protection activities including predator control, nest screening, and relocation of nests to protected self-releasing hatcheries. Many coastal communities have enacted lighting ordinances restricting beach lights during the nesting and hatching period. Federal and state regulations have been implemented requiring turtle excluder devices on shrimp trawls. Federal and state efforts are underway to purchase key nesting beaches. Research is underway to determine natural hatchling and juvenile sex ratios, identify juvenile habitats, investigate hatch¬ ling orientation mechanisms, elucidate adult interseasonal movements and migratory routes, assess the effects of persistent marine debris on sea turtles, and develop safer dredging technology. CORRELATIONS OF AGE TO ROD AND CONE DENSITIES OF THE RETINA. IN THE GREENSIDE DARTER (ETHE0ST0MA BENNIOIDES) . Michael Pugh, Cris Cole, and Ronald Jenkins, Dept, of Biology, Samford University, Birmingham, Alabama 35229. Feeding behavior of the greenside darter changes from diurnal feeding to nocturnal feeding with increasing age. This study deter¬ mines if there is a correlation of this feeding behavior to photo¬ receptor populations in the retina. Sixteen greenside darters were collected and preserved immediately in formalin. Standard body lengths (snout to anal fin base) were measured and all eyes were prepared for histological sectioning in paraffin. Entire eyes were completely sectioned through the optical axis in eight (8) micron sections and stained with H. and E. The sections through the optic axis were chosen according to thickness of the retinal nerve fiber layer and total retinal thickness. Rods and cones were distinguished in that cone nuclei were adjacent to the external limiting membrane and pyramidal in shape. Total number of rods and cones were counted over a horizontal distance of 1800 microns. In longer animals, rod densities increased, cone densities decreased, and the rod/cone ratio significantly increased. There is a correlation of the nocturnal feeding behavior in the greenside darter to declining cone densities. 136 Abstracts PRODUCTION AND CHARACTERIZATION OF MONOCLONAL ANTIBODIES AGAINST STICK INSECT VITELLOGENINS. B. Estridge, and J_,_ Bradley . Dept. Zoology & Wildlife Sciences, Auburn Univ. , AL 36849. A. Cecchettini, M. Mazzini, and F. Giorgi, Istituto di Istologia e Erabriologia, Univ. of Pisa, 56100 Pisa, ITALY. Vitellogenin (VG) , from which yolk proteins are derived, is synthesized by insect fat body, secreted into the hemolymph, and sequestered by oocytes via receptor-mediated endocytosis. Little is known about the mechanism of VG processing and secretion in insects. This study reports the production and characterization of monoclonal antibodies (Mabs) specific for vitellogenins of the stick insect, Carausius morosus . and their use as tools to study vitellogenesis. Hybridoma cell lines producing VG-specific antibodies were generated by fusing non-secreting mouse myeloma cells with spleen cells from mice immunized with stick insect egg VG. A library of Mabs reactive with VG by enzyme immunoassay was obtained. By electrophoresis under denaturing conditions, native stick insect VG molecules A and B can be separated into five polypeptide subunits - -Al , A2 , and A3 and B1 and B2 , respectively. Five Mabs reactive with single VG subunits, two Mabs reactive with multiple VG subunits, and one Mab reactive with an egg specific protein (ESP) have been identified using immunob lotting techniques. One of the antibodies was also found to react with fat body pre-VG. A preliminary experiment using brefeldin A (BFA) , an inhibitor of protein secretion, indicates that fat body secretion of VG decreases following in vitro exposure to concentrations of BFA above 5 ug/ml.

Poirier, Dept, of Biology, University of Alabama at Birmingham, Birmingham, AL. Murine spermatazoa use a trypsin-like proteinase molecule to bind to the zonae of homologous oocytes. Previous investigations, using a monoclonal antibody to this molecule, suggest that the initial in vitro exposure of the epitope in the acrosomal cap region of the sperm head is by the dilution of epididymal fluid. By 90 minutes of incubation at 37 C the epitope becomes visible on the equatorial region of the sperm head. Exposure in both the equatorial and the acrosomal cap regions can be blocked by an in vitro incubation in the supernatant of washed caudal epididymal sperm or in a partially purified (gel-filtration and ion-exchange chromatography) preparation. The blocking component of the supernatant is heat labile with a molecular weight of approximately 17-19,000 daltons. Furthermore, the binding of the monoclonal to epitope exposed sperm can be blocked by treatment with a crude or partially purified preparation. The data are interpreted to mean that the epitope is first exposed in the acrosomal cap region by dilution and with incubation, in the equatorial region by the removal of a masking component in the epididymal fluid.

Lindsay, Department of Pathobiology , Auburn University AL 36849 Caryospora bigenetica is a coccidian parasite of snakes and mam¬ mals. The genus is unusual in that both asexual and sexual stages occur in both the reptilian and mammalian hosts. When mammals are infected, severe dermal coccidiosis usually occurs, and mortality is not uncommon. Caryospora bigenetica is unusual in that it can also undergo its entire developmental cycle in vitro in cultured cells of several types. For this study of development under long term maintenance conditions, spor¬ ozoites were purified from oocysts of rattlesnake origin and added to flasks of monolayers of human fetal lung (HFL) cells. By Day 15, the coccidian had completed development and formed caryocysts; the flasks were then split, and development occurred again. On Day 58, some monos of HFL cells were deteriorating, so RPMI medium with 10% fetal bovine serum was added to the flasks. This stimulated division of the HFL cells and C. bigenetica underwent another round of development with both asexual and sexual multiplication occurring. On Days 77, 92, and 153, the monolayers were split with either cell scraping or with addition of trypsin-EDTA (and removal of Ca-H- and Mg++) which caused the HFL cells to detach. Each split induced C_. bigenetica to undergo another develop¬ mental cycle. On Day 197, HFL cells were chemically lysed and caryo¬ cysts were liberated. These caryocysts were inoculated onto fresh monolayers, and development of the coccidian occurred. Some infected HFL cells also were frozen in liquid N£ in order to study cryopreserva- tion of the parasite. This is the first report of a coccidian under¬ going both asexual and sexual development continuously under in vitro conditions. Supported by the Alabama Agricultural Experiment Station. The Pocosin of Pike County Alabama. Alvin R. Diamond, Jr. Troy State University Arboretum, TSU AL 36082 Six miles due east of Troy on the east side of Walnut Creek, the Pocosin encompasses an area of about a half square mile. The word Pocosin is of Indian origin and was originally applied to evergreen swamps in North Carolina. The Pike County Pocosin contains a large number of ever¬ green species but is by no means a swamp. Deep white nutrient poor and extremely xeric sands underlie the area. Vegetation consists mainly of dwarfed oakes, including Arkansas Oak (Quercus arkansana ) , few if any over 30 feet tall. Pines are almost totally absent. Except for lichens and spotty patches of wiregrass and sand cactus ground cover is lacking. In such open areas the rare Warea sessil i f ol ia is found. These bare areas provided a block to fires on the uplands and protected several deep horse-shoe shaped ravines. Approximately 200 feet from side to side and up to 100 or so deep each has a spring at its base. Numerous species of saprophytes are found there under the mostly evergreen hardwood cover such as ghost pipes, pine sap and nodding nixie. Unf orunately , almost all of this unique area has been transformed into hay fields, pine plantations or mobile home parks. 138 Abstracts LABORATORY CULTURE AND LIFE CYCLE OF THE NUDIBRANCH BERGHIA VERRUCI CORNI S . David J. Carroll , Dept, of Zoology and Wildlife, Auburn University, A1 36849. Stephen C. Kempf, Dept, of Zoology and Wildlife, Auburn University, Al. 36849. The complete life cycle of Berghia verrucicornis was studied using seasoned laboratory aquarium water for all cultures. Adult 13. verruci¬ cornis lay white, spiral egg masses containing fifty to several hundred embryos. At the time of laying the embryos are in the zygote stage; development proceeds quickly with the first division beginning 2-2.5 hours after laying. The bilobed velum is apparent at the end of the second day after oviposition, and the larval shell appears on the beginning of the third dag. Hatching occurs 11 to 12 days after the egg mass is layed (23.9 + 1.3 C) resulting in the release of lecithotrophic veliger larvae. Poecilogony occurs; both larvae and juveniles hatch from the same undisturbed egg mass. Metamorphosis occurs 1 to 2 days after hatching and involves the loss of the velum and larval shell. The newly metamorphosed juvenile is compact, but lengthens considerably overnight. 3 to 4 days after metamorphosis the juveniles begin feeding on laboratory reared clones of the sea anemone Aiptasia pallida . The juveniles reach reproductive maturity (adulthood) on the average of 6 to 7 weeks after oviposition, but the laying of the first egg mass has been observed as early as 4 weeks after oviposition in the lab. j3. verrucicornis offers several advantages for inland investigators who wish to work with opisthobranch molluscs in the lab. It lays egg masses year round, with regularity, and with a considerable number of eggs; the embryonic (10-12 days) and larval (1-5 days) periods are short, neither feeding nor antibiotics is needed during larval culture, and the juveniles and adults are easily reared in the lab. SYMBIOSIS BETWEEN A ZOOXANTHELLA AND THE NUDIBRANCH BERGHIA VERRUCICORNIS. A "PRIMITIVE" ASSOCIATION? Stephen C. Kempf. Department of Zoology and Wildlife Science, Auburn University, AL 36849 As the aeolid nudibranch Berghia verrucicornis feeds on the anemone Aiptasia pallida, the dinoflagellate zooxanthellae living in Aiptasia’s entodermal cells are transferred, along with anemone tissue, into the lumina of the ceratal digestive diverticula. Here the algal symbionts, and presumably anemone tissue, are phagocytosed by nutrient processing cells (NPCs) lining the diverticula walls, the zooxanthellae coming to reside intracellularly within membrane bound vesicles. Any given algal cell is transient within the NPCs, eventually being exocytosed and passed out of the digestive tract in Berqhia’s feces. Field and lab populations of Berghia maintain a high concentration of symbionts within their NPCs as they regularly feed on Aiptasia. Division stages of the algae are present within the NPCs and their is no evidence of active digestion of the algae in the ceratal tissues or fecal pellets. The concentration of zooxanthellae slowly decreases over a 1 7 day period of starvation; however, the algal cells are never totally lost. Evidence obtained thus far suggests that this association is a "primitive" symbiosis. 139 Abstracts A COMPARISON OF SOMATIC AND TESTICULAR HISTONE PROTEINS FROM THE SEA STAR ASTERIAS VULGARIS. Carl B. Massey and Stephen A. Watts, Dept, of Biology, Univ. of Ala. at Birmingham, Birmingham, AL 35294. Samples of whole histone (HI ,H2A,H2B ,H3 , and H4) were prepared either by protamine displacement or acid extraction. Histones were examined electrophoretically employing one dimensional acetic acid-urea polyacrylamide gels (5% acetic acid-2. 5M urea-157. acrylamide) and acetic acid-urea-Triton X-100 gels (5% acetic acid-6M urea-6mM Triton- 127. acrylamide) for second dimensional analysis. In male gametogenic tissues, the predominant HI protein exists as a slow-migrating variant differing significantly from HI found in somatic tissue (pyloric caeca). A minor band migrating with somatic type HI was also observed in testicular extracts. This minor protein band represents either (1) the HI contribution of the small number of somatic cells present in the mature testes, or (2) low-level expression of the somatic type HI in male germinal cells. Nucleosomal histones (H2A, H2B , H3 , and H4) from both testicular and somatic tissues exhibited similar electrophoretic patterns. Therefore, A. vulgaris appears to possess primarily one testis or sperm-specific histone (SpHl) as evidenced by comparison with testicular histones of the sea urching Strongylocentrotus drobachiensis which exhibits a distinct SpH2B and SpHl. These data indicate that histone variants functioning in spermatogenesis may be present as variants of different histone isotypes (H1,H2B and possibly others) in different organisms. Thus, variable histone/DNA interactions necessary during spermatogenesis may be mediated through several different but functionally related protein variants, and the scheme adopted by the organism may be related to its phylogeny.

Wooten, Dept, of Zoology/Wildlife, Auburn Univ., Auburn, AL 36849 We used PC12 cells as an in vitro model to examine the effects which alcohols have upon cellular differentiation. PC12 cells treated with 30ng/ml NGF and 87mM ETOH underwent rapid neurite extension, as compared to NGF alone. Cells treated with alcohols displayed an increase in neurite length and number, a decrease in 3H- thymidine incorporation and a dramatic 4-fold increase in acetylcholine esterase activity as compared to control or NGF treatment alone. The synergism observed between NGF (30ng/ml) in promotoing neurite extension was directly correlated with the side chaine length of the alcohol BuOH>PrOH>EtOH>MeOH. Alcohol differentiated PC12 cells contained 3-4 fold greater amounts of protein kinase C activity. Pretreatment of these cells with sphingosine (2.5/iM), a specific PKC inhibitor, prevented differentiation and accumulation of PKC. These data suggest an intimate relationship between PKC and cellular differentiation. 140 Abstracts STATUS OF ENDANGERED BEACH MOUSE POPULATIONS IN ALABAMA. Nicholas R. Holler and Elizabeth H. Rave, Alabama Cooperative Fish and Wildlife Research Unit, Dept, of Zoology and Wildlife Science, Auburn University, AL 36849-5414. Two endangered subspecies of beach mice (Peromyscus polionotus) occur on the coastal dunes of Alabama. The Perdido Key beach mouse (P. £. trissyllepsis) formerly occurred in more or less continuous populations along the coast of Perdido Key in Alabama and Florida. In April 1986 it existed only as one small population of less than 30 individuals in Alabama. The population had increased greatly by April 1987 and numbered more than 100 by November 1987; it appears to have stabilized at that level. A second population has been established at Gulf Islands National Seashore in Florida through translocation. That population has occupied 11,000 meters (approximately 160 ha) of dune habitat and exceeded 100 individuals in January 1990. The Alabama beach mouse (P. £. ammobates) formerly occurred on Ono Island and along the coast from Perdido Pass to Fort Morgan. It was extirpated from Ono Island by 1982. In 1987, we found remaining populations at and between Bon Secour National Wildlife Refuge (Perdue Unit) and Fort Morgan. Alabama beach mice may now be extirpated from Gulf State Park, where domestic cats (Felis silvestris) are common and house mice occur. In November 1987, 8 house mice (Mus musculus) but no beach mice were captured in 5 nights of trapping (910 trap nights). Trapping at Bon Secour National Wildlife Refuge and Fort Morgan 1987 through 1989 showed that those areas remain occupied. Tropical storms pose the most serious threat to remaining populations. Captive colonies are being maintained at Auburn University to guard against the potential loss of wild populations. EXPRESSION OF PROTEIN KINASE C ISOFORMS DURING DIFFERENTIATION OF PC12 CELLS. K. Beth Beason and Marie W. Wooten, Dept, of Zoology/Wildlife, Auburn Univ. , Auburn, AL 36849 Protein kinase C is a gene family composed of 3 highly related members, alpha, beta and gamma. Selective expression of the various encoded isoforms have been examined in several tissues, in addition to various established cell lines. Using brain as a standard we have compared the expression of PKC isoforms in the pheochromocytoma cell line, PC12 . Undifferentiated PC12 cells express two of the encoded protein isoforms, PEAK II=beta and PEAK III=alpha. An intimate relationship between PKC activation and differentiation of PC12 cells has been established. We were therefore interested to examine the expression of PKC isoforms during differentiation of these cells. Cells were harvested after being treated with inducer and probed by Western blots with isoform specific antibodies. Our results reveal an increase in the gamma-isoform. We are currently examining the time course and induction of the various mRNA ' s for these isoform proteins. 141 Abstracts LONG TERM EFFECTS OF TEMPERATURE ON THE GROWTH AND REPRODUCTION OF THE TROPICAL SEA URCHIN, EUCIDARIS TRIBULOIDES. Michael T. Lares and James B. McClintock, Dept, of Biology, Univ. of Alabama at Birmingham, Birmingham, AL 35294. Individuals of Eucidaris tribuloides were held at temperatures of 18 and 27°C for a period of seven months to examine the effects of temperature on somatic growth and reproduction. Growth, as measured by changes in wet weights and test diameters, was monitored monthly and reproductive condition was ascertained at the conclusion of the seven months. Individuals held at 18°C showed little or negative growth throughout the seven month period (mean growth/month = -0.12 ± 0.21 g wet wt; 0.2 ± 0.8 mm test diameter). However, individuals held at 27°C increased in size (mean growth/month = 0.24 ± 0.35 g wet wt; 0.2 ± 0.2 mm test diameter). The gonads of individuals held at 18°C were generally small (mean gonad index = 4.13 ± 3.00) and lacked definitive gametes, whereas the gonads of individuals held at 27°C were large (mean gonad index = 7.96 ± 2.20) and contained numerous mature gametes. The results of this experiment indicate that temperature has a pronounced effect on the somatic growth and gonadal development in this common, tropical sea urchin.

Despite heated controversy regarding intense overfishing on several marine species, there are currently no species of marine fishes off the north central Gulf coast which appear to be in any danger of approaching critically low population levels. Populations of economically important species may be below optimal, but their reduced abundance would not be construed as even remotely threatening their survival as species. However, there are several poorly known cryptic species occurring in specialized habitats along the mid shelf region whose status is unclear. Two of these are chaenopsid blennies, Chaenopsis roseola, the flecked pikeblenny, and Emblemaria piratula, the pirate blenny. Both species app'ear restricted to rubble/shell hash bottoms of the northeastern Gulf of Mexico at depths of from approximately thirty to sixty meters. The former species may have a greater geographical range, but the status of its close congeners is currently unclear. The pirate blenny appears to have a more restricted range. Several other poorly known cryptic forms (e.g. Cobulus myersi, Palatogobius paradoxus, and Gillelus sp.) co occur on this distinctive substrate. While none of these species is herein considered threatened or endangered, their possible limited range and apparent specialized habitat render them most vulnerable in the event of major environmental modification in the Gulf of Mexico. 142 Abstracts POPULATION DYNAMICS OF THE FRESHWATER GASTROPOD PHYSELLA CUBENSIS, Donald Thomas and James McClintock, Dept, of Biology, University of Alabama at Birmingham, AL 35294. The population densities, s ize- frequency distributions and reproductive activities (egg mass abundnace) of the freshwater pulmonate gastropod Physella cubensis were examined during 1989 at three sites in Shades Creek, Birmingham, Alabama. A fourth site in an adjacent ephemeral pond habitat was also sampled. Stream sites I and II were gravel/mud habitats while site III was a rock-shelf habitat. Total numbers of individuals/m2, individual sizes, numbers of deposited egg masses, temperature and precipitation were recorded at two week intervals. Snails appeared in the stream sites in June and attained peak mean densities of 35, 30, and 10/m2 in sites I, II and III, respectively. Stream-site snails were absent by the end of September. Snails were present in the pond site from January through October reaching multiple peak mean densities of 363, 280, 275 and 101/m2 in March, April, July and September, respectively. Size- frequency analysis indicates that growth occurred slower in the stream than in the pond, with stream populations having two generations/year and pond populations having six or more generations/ year. Egg masses first appeared in the stream sites in June and in the pond site in April. Egg mass abundance was positively correlated with larger sized individuals (5-10 mm shell length). The population dynamics of P. cubensis appear to be regulated by such factors as habitat structure, precipitation, food availability, and particularly, temperature . REPRODUCTION IN CAPTIVE SANTA ROSA BEACH MICE (PEROMYSCUS P0LI0N0TUS LEUCOCEPHALUS) AND CHOCTAWHATCHEE BEACH MICE (P. P. ALLOPHRYS) . Karen L. Fleming and Nicholas R. Holler, Alabama Cooperative Fish and Wildlife Research Unit, Dept, of Zoology and Wildlife Science, Auburn University, AL 36849-5414. Reproductive data were collected on captive Santa Rosa beach mice (Peromyscus polionotus leucocephalus ; SRBM) and captive Chocta- whatchee beach mice (P. £. allophrys ; CBM) at the Alabama Cooperative Fish and Wildlife Research Unit, Auburn University, from January 1987 to January 1990. Data were analyzed for all continuously paired wild-trapped females (SRBM, n=20; CBM, n=5) and for first generation captive-born females paired at age 60 days with first generation cap¬ tive born males age 60-90 days (SRBM, n=28; CBM, n=9) . Seventy-one percent (20) of SRBM first generation females and 56 percent (5) of CBM first generation females produced young. An ANOVA showed signi¬ ficant differences (p < .05) between subspecies for mean days to first littering (SRBM, 148 + 122 days; CBM, 331 ± 159 days) and mean numbers of litters in first year after pairing (SRBM, 5.9 ± 3.3; 1.8 ± 2.5). Mean litter sizes were 4.12 ± 1.32 for SRBM and 4.31 ± 1.64 CBM and did not differ significantly (p < .05). Likewise, mean litter weights, young weights, number of males, number of females, number of litters in first year after pairing, and litter interval did not differ significantly (p < .05) between subspecies, between generations within a subspecies, or between like generations of separate subspecies. 143 Abstracts TOXOPLASMA GONDII: CHARACTERIZATION OF MONOCLONAL ANTI¬ BODIES GENERATED AGAINST TACHYZOITES. D. S. Lindsav. Dept. Pathobiology, Auburn University, AL 36849, J. P. Dubey, USDA, Zoonotic Dis. Lab., Beltsville, MD 20705 and B. L. Blagbum, Dept. Pathobiology, Auburn University, AL 36849. Toxoplasmosis is a serious disease of man and other warm-blooded animals. Mental retardation and blindness are common in transplacentally infected children. Toxoplasmic encephalitis is a fatal condition that develops in many Toxoplasma gondii seropositive AIDS patients. Cats are the only known definitive host for T. gondii. Infectious stages of the parasites are classified as sporozoites, tachyzoites or bradyzoites. We made monoclonal antibodies (MAB) to tachyzoites of the highly pathogenic RH isolate by immunizing BALB/C mice with killed tachyzoites collected from cell cultures. Following fusions of immune spleen cells with myeloma cells, two hybridomas were identified that reacted with tachyzoites in an IFA test. Positive hybridomas were cloned by limiting dilution. One of the MABs (TG-1DE4C) gave a tachyzoite pellicle surface binding IFA pattern and the other MAB (TG-2AB2A) gave a anterior end binding IFA pattern. MAB TG- 1DE4C was specific for tachyzoites while, MAB TG-2AB2A also reacted with sporozoites an bradyzoites of T. gondii. Additionally, MAB TG-2AB2A reacted with Neospora caninum tachyzoites and Eimeria bovis merozoites. Neither MAB protected mice from lethal infection with the RH isolate. GEOGRAPHY, SEASONALITY, SIZE, DEAD IN ALABAMA SINCE 1987. Spring Hill College, Mobile, AND SEX OF BOTTLENOSE DOLPHINS FOUND Gerald T. Regan , Department of Biology, AL 36608. The design had been to report results through calendar 1989, but was extended to include the first 46 days of 1990 either by expanding the database or simply adding the 1990 results as such as time permitted. From April 1, 1987 through February 15, 1990, of 42 cases, n ii-Wo[e °n the Gulf beaches: Dauphin Island 21*; Mobile Point 21*; Gulf Shores - Roraar Beach 12*; Perdido Key 5*. The Bays had 40*: Mobile Bay 21 *; Perdido Bay 19*. At Dauphin Island, over half were on the Mississippi Sound side. In Mobile Bay, the northmost was at Dog River; more than half the cases were between Point Clear and Mullet Point. From April 1, 1987 through 1989, 40* of 30 cases occurred in March and April, the rest scattered evenly in other months. In 1990, there were 12 cases, including two mummies, by mid- ebruary. Of 34 cases that could be sexed, 68* occurred in the first tour months of the year, males outnumbering females 14 to 9 then, 1990 a a included. Of 23 measurable cases before 1990, 47* exceeded 230 cm (max 247) and 26* were below 110 cm (neonate) standard length Females averaged 205 cm (max 247), males 198 (max 270), 1990 data included. Of 11 weighed before 1990 the range was 21-251 lbs. In early 1990 cases of 334, 376, 426, and 475 lbs appeared, all males. Of cases that could be sexed, before 1990 56* of 25 were females but in early 1990 78* of 9 were males. 144 Abstracts CHEMISTRY DIASTEREOMERJC DERIVATIZATION AND LIQUID CHROMATO¬ GRAPHIC ANALYSIS OF N-(PHENYLSULFONYL)-2-PHENYLGLYCINE ALDOSE REDUCTASE INHIBITORS. Kamal Bouhadir. C. Randall Clark, Charles A. Mayfield and Jack DeRuiter, Department of Pharmacal Sciences, School of Pharmacy, Auburn University, AL, 36849. A series (5)- and (R)-N-(phenylsulfonyl)-2-phenylglycines were synthesized as potential inhibitors of the enzyme aldose reductase. In vitro analysis demonstrates that the S-enantiomers are more inhibitory than the R-enantio- mers and that the differences in potencies between enantiomeric pairs is dependent on the electronic nature of ring substituents. To ensure that this enantioselectivity does not reflect varying degrees of racemization during the syntheses, the enantiomeric purity of the N-(phenylsulfonyl)-2-phenylglycines was determined by HPLC after chiral derivatization. Each 2-phenylglycine product was derivatized with (R)-methylbenzylamine and the resulting diastereomers analyzed using reversed and normal achiral stationary phases. Reversed-phase methods with Cjg or phenyl stationary phases and solvent mixtures of acetonitrile or methanol in water did not provide satisfactory diastereomer resolution. Normal phase analyses with a silica stationary phase and mixtures of methanol, ethanol or acetonitrile in chloroform provided good separations with relatively short analysis times. The normal phase analyses demonstrate that a single diastereomeric amide formed from each N-(phenylsul- fonyl)-2-phenylglycine product, establishing that these compounds did not racemize during synthesis. TRANSAMINATION AND THE SYNTHESIS OF AMINOARS INE S . Colacot J. Thomas , Larry K. Krannich and Charles L. Watkins , University of Alabama at Birmingham, Alabama 35294. Aminoarsines are a class of As-N compounds which have shown significant synthetic potential in organometallic and coordination chemistry. Despite their applications, the number of aminoarsines known in the literature is limited. Although several publications have appeared on the synthesis of aminoarsines/phosphines by the t ransaminati on ( transesterification ) route, the general utility of this pathway as compared to aminolysis has received little attention. In this paper, we will discuss the synthetic merits and certain mechanistic implications of transamination reactions. A variety of ami iPr2N-, nBu2 C5H10N~, C6H12N" and ninoarsines of the type Me2AsR [R=Me2N~, Et2N-, nPr 2N-, N— , 1Bu2N-, Ph2N-, (PhCH2)2N-, (C6Hn)2N-, C4HRN-, CH3NC4Hr1 N-] have been synthesized by the aminolysis and transamination routes. This study suggests that transamination reactions are primarily sterically controlled, whereas electronic effects dominate aminolysis reactions. *H-NMR spectral details of these arsines will be discussed. 13 C and 145 Abstracts SYNTHESIS OF HETERO-FUSED ISOQUINOLONES. Forrest T. Smith, Venkat Ram Atieadda. Jack DeRuiter, School of Pharmacy, Auburn University, Auburn, Alabama 36849. The reaction of 7-methoxyphthalic anhydride with heterocycles containing a basic azomethine linkage has proven to be quite successful in providing a variety of hetero-fused isoquinolones. Although thiazole, oxazole and imidazole fail to give the desired compounds 1-pyrroline, 1-pyrroline trimer, and 2-thiazoline give the carboxy-substituted heterocycles in high yield. The results favor a mechanism by which there is an initial attack of the imine on the anhydride at C-l followed by attack of the acyl iminium cation by the generated enol. A cycloaddition mechanism or prior abstraction of the C- 4 proton are not supported by these results. Support for this research has been provided, in part, by the W. W. Walker, Jr. Endowment. UV STUDIES OF STERICALLY RESTRICTED ARENETRICARBONYLCHROMIUM COMPLEXES. D. Radzvkewycz. J. Rawlings, and C.A.L. Mahaffy, Dept, of Chemistry, Auburn University at Montgomery, Montgomery, AL, 36117. The UV-visible spectra for a variety of substituted arene tricarbonylchromium complexes have been obtained. Arenes which contain acetyl, ester, or vinyl groups which are not sterically hindered at the 2- or 6- position form arenetricarbonylchromium complexes which show an absorption maximum in the 420 nm region; this band gives these complexes their characteristic orange color. Arenes which have a substituent ortho to the unsaturated group have this band shifted to somewhat shorter wavelengths. When the arene is 2 , 6-disubstituted, the complex is yellow and the absorption maximum is no longer apparent. NEW METAL COMPLEXES USEFUL AS ENZYME INHIBITORS. J. Rawlings, Dept, of Chemistry, Auburn University at Montgomery, Montgomery, AL 36117. The kinases are a class of enzymes that require MgATP for activity. By synthesizing and characterizing substitution-inert metal complexes of ATP, these enzymes have been shown to have a steric preference for particular conformations of the metal-ATP complex. Hexokinase, for instance, preferentially uses a lambda metal-ATP complex. This paper will present the synthesis, isolation, and characterization of new metal-ATP complexes and will also discuss their steric interactions with hexokinase. 146 Abstracts PEOX-co-PEI/URACIL OR 5-FLU0R0URACIL POLYNUCLEOTIDE ANALOGS: STRUCTURAL CHARACTERIZATION. Kevin W. Carter and A. G. Ludwick. Chemistry Department, Tuskegee University, Tuskegee, AL 36088 The project is designed to study the antiviral activity of the uracil or 5-fluorouracil analog and correlate the results with structural characteristics. The analogs are synthesized by the reaction of an intermediate succinimide ester with a 50% hydrolyzed polyethyloxzaline copolymer (PEOX-co-PEI). Structural characterization of the uracil and 5-fluorouracil analogs is underway using spectroscopic analyses. Antiviral activity of the analogs will b< examined at Southern Research Institute. (Supported by NIH/MBRS) ECKART'S CRITERION APPLIED TO SIMPLE QUANTUM MECHANICAL MODELS. Robert Mathews, Mobile College, Mobile, AL 36613. Only the very simplest systems can be solved exactly in quantum mechanics, making approximate solutions necessary for problems of interest. How accurate are the approximate solutions? The variation theorem guarantees that the energy of any valid approximate solution must exceed the true energy of the system, and it is generally assumed that the lower the energy, the more accurate the approximate solution. Recent studies have shown that lower energies do not always correspond to better solutions, since such quantities as the dispersion of the energy may increase. Eckart established that the mean-square error in the wavefunction decreased as the energy of the approximate solution decreased. By using computer spreadsheet programs, it is easy to demonstrate Eckart' s criterion. Sample calculations and their instructional use will be discussed. 147 Abstracts QUANTUM MECHANICAL PREDICTION OF TAUTOMERIC EQUILIBRIA FOR THE PURINE BASES. .Terzv Leszczvnski. Department of Chemistry, University of Alabama at Birmingham, University Station PHS-219, Birmingham, AL 35294. Chemical studies show that DNA has the structure of a long-chain poly¬ mer consisting of alternating phosphate and nitrogen base-substituted sugar residues. One of the four bases, adenine, guanine, cytosine , and thymine is bonded to each of the sugar residues. The hydrogen bonds formed be¬ tween base pairs lead to linking the two strands of DNA helix. From the point of view of structural chemistry and molecular biology a knowledge of relative stabilities of tautomeric forms of nucleic acid bases (NAB), as well as of the tautomeric conversion from one form to another is important. Watson and Crick suggested that the spontaneous point mutations might be due to mispairing by rare tautomeric forms of purinic and pyrimidinic NAB. The stabilities of several isolated tautomers of ■purine, adenine and gua¬ nine are discussed by considering their relative internal energies predicted by ab initio quantum mechanical calculations. The contributions of the SCF, zero point vibrational energy and electron correlation for calculation of the relative tautomer stabilities are studied. The stabilities of the guanine tautomers are compared with similar calculations for isocytosme tautomers. An effect of the environment on the relative stabilities of several tautomers is also discussed. OPTIMIZATION OF A FLOW INJECTION ANALYSIS SYSTEM FOR LACTATE. Moore U. Asouzu, Dept, of Chemistry, Troy State Univ., Troy, AL 36082. William K. Nonidez, Mat H. Ho, Dept, of Chemistry, Univ. of Ala . -Birmingham , AL 35294. Lactate analysis by enzyme amplification and ampero- metric detection was adapted to flow injection analysis. The operating parameters of this system were optimized by the simplex method, and maximized by the univariate method. Results obtained under conditions predicted by both methods were compared. It was found that the sensitivity of the linear portion of the calibration curve prepared under the simplex conditions was 1.2 times better than that of the calibration curve generated with the values determined by univariate maximization. The detection limit was 0.119yUM and 0.329 / 100 nM (< 15% patches) ; and 7. a flickering type 250 pS channel when [Ca+2]j > 200 nM. We feel that chloride channels are involved in the maintenance of the membrane potential in VSM cells; a change in chloride channel activity can alter the membrane response due to voltage changes. 211 Abstracts Variation In Scrum Transferrin and ImmunogJobin levels with Age and with Lipoprotein Cholesterol Fraction Levels. Kamal S. Yackzan and Barry M. Gray, Departments of Cell Biology and Anatomy, and Pediatrics, University of Alabama at Birmingham, AL 35294, U.SA. The concentrations of four plasma proteins, transferrin (TO, immunoglobulins IgG, IgM, and, IgA were measured in 158 subjects aged 8 to 80 years and in 207 subjects (ages 30-50 years) with varying levels of lipoprotein cholesterol levels [high density lipoprotein (HDL), low density lipoprotein (LDL), high levels of both HDL and LDL high cholesterol levels (HCL), low cholesterol levels (LCL), and normal controls]. Regression analysis revealed that Tf and IgM concentrations decreased with increasing age (p<0.001). IgA levels increased with increasing age (p<0.05). IgG levels were independent of age. It is postulated that with increaseing age and decreaseing energy requirements there is decreased demand for iron transfer in the body tissues. The data also showed that Tf levels increased as LDL rose. In the high total cholesterol level group (HCL) Tf levels were significantly lower than in controls. Beyond these observations one may conclude that there was little association between the levels of Tf and immunoglobulins and altered levels of plasma lipoprotein cholesterol fractions.

Dept, of Structural & Cellular Biology, University of South Alabama, Mobile, AL 36688, Ian S. Zagon, Dept, of Anatomy, Pennsylvania State University, M.S. Hershey Medical Center, Hershey, PA 17033, and Steven R. Goodman, Dept, of Structural & Cellular Biology, University of South Alabama, Mobile, AL 36688. In the current study, we have investigated the interaction of brain spectrin with 50 nm diameter synaptic vesicles. Small synaptic vesicles, radiodinated with 125I-Bolton-Hunter reagent were incubated with brain spectrin covalently immobilized on cellulosic membranes. Binding was found to be rapid (equilibrium is reached in 1 min), salt dependent (optimum at 50-70 mM NaCl), and pH dependent (optima at 6.5 and 7.5 -7.8). Scatchard analysis revealed biphasic binding isotherm suggesting that spectrin binds to at least two distinct classes of noninteracting sites: high affinity (Kj)~31 ug/ml) and low affinity (Kj)~126 ug/ml). Synaptic vesicles extracted with high salt solution displayed little binding capacity towards brain spectrin. To identify potential membrane attachment sites, spectrin was covalently bound to a cellulosic membrane in a affinity chromatography unit and the vesicles were passed through. Adhering vesicles were solubilized with 0.2% Tween 20 and bound protein was recovered by elution with 0.2 M KC1, 0.2% Tween 20 in the same buffer. SDS polyacrylamide gel electrophoresis and western blot indicated that eluted protein bands were primarily synapsins. Isolated synapsin I was found to competitively inhibit the binding of 125I-synaptic vesicles to brain spectrin with an apparent Kj of 59 nM synapsin I. The above findings are consistent with the cytoskeletal-mediated release hypothesis, in which the spectrin-synapsin interaction is proposed to be critical to the regulation of synaptic vesicle translocation and fusion. 212 Abstracts PILOT STUDY: SHORTAGE OF LAB PERSONNEL?. Katherine L. Bradshaw and William R. Krause, University of Alabama, Tuscaloosa, Alabama 35401. C. George Tulli, Jr., CMC, Univ. of Ala., Tuscaloosa, AL 35401. Is there a shortage of lab personnel in the state of Alabama? In order to answer this question, a pilot study of fifty hospitals was conducted. The questions used in this study were taken from a 1988 national survey commissioned by the ASCP. The results of the ASCP survey, published in the June 1989 edition of Laboratory Medicine , showed a national vacancy rate of 9.4 percent for medical technologists. In order to find where the greatest shortage exists in Alabama, the state was divided into four districts: Mobile, Montgomery, Birmingham, and Huntsville. From this limited sample, the results showed that the FTE vacancy rates for medical technolo¬ gists in the four districts were as follows: Mobile, 8.33 percent; Montgomery, 8.42 percent; Birmingham, 6.04 percent; and Huntsville, 7.69 percent. The overall percentage for the state as a whole was 7.43 percent. Several solutions have been posed to address the problem of the shortage of lab personnel. One interesting alternative that has been implemented in several institutions is the use of temporary technologists. Over fifty-three percent of the sample hospitals used temporary technologists. Almost one-half of these hospitals had a supplier that provided the temporary technologists. Some of the other solutions that have been tried are local and national advertising, salary increases, subsidized tuitions, recruitment tactics through high schools, and restructuring of lab duties and responsibilities. TRANSFERRIN AND IMMUNOGLOBULIN LEVELS IN HUMAN AMNIOTIC FLUID OF NORMAL PREGNANCY Kamal S. Yackzan and Nona Colburn, Department of Cell Biology and Anatomy, Univ. of Alabama at Birmingham, Birmingham, AL 35294 U.S.A. Amniotic fluid is important in clinical diagnosis of intrauterine infections in amniotic fluid. Controversy still exists regarding role, correlative relation between IgG, its increase, & its source in amniotic fluid and the growth of the fetus during weeks of increasing gestation period. Many studies have found no correlation. Quantitative analyses for IgG, IgM, IgA and transferrin levels were performed on forty amniotic fluid and forty maternal gestation serum samples using Mancini's single radial immunodiffusion method. All subjects had normal pregnancies. Ig levels in maternal sera were similar to non pregnant controls (p 0.05). However by use of linear regression analysis a positive correlation was found between IgG levels in amniotic fluid and the stage of gestation. An increase of gestational age by 1 week increased IgG level by 0.8 mg/dl. This study postulates that IgG source is not strictly maternal in origin. The increase in Ig level may be contributed by synthesis in the fetus. The limited sensitivity of this method for Tf allowed us to detect this protein in five out of fifteen samples. Clinical relevance of this relation may be enhanced by further study of these proteins for detection of intrauterine infection. [Thanks to C. Krauth, Dr. L. R. Boots, and Dr. B. R.

Norris, DSN, RN, Critical Care Nursing, Baptist Medical Center Montclair, Birmingham, Alabama 35243. The physiologic response to exercise in clients with MVPS is not fully understood. To determine if two subsets of clients with MVPS had a significantly different response to exercise than a group of normal a retrospective research design was implemented. The sample consisted of 72 subjects who had received a metabolic GXT (MGXT) at a local center. The MGXT records of 24 normals. 24 MVP clients with hyperadrenerg ic dysautonomia and 24 MVP clients with hypervagal dysautonomia were reviewed. The following variables were examined: resting heart rate (HR), peak exercise HR, resting systolic BP and peak exercise SBP, Peak V02 , time to peak V02 , Met level reached and rate of perceived exertion. The statistical hypotheses were tested using analysis of variance procedures. The F statistics indicated no significant difference at the .05 level of significance among the three groups for the variables included. It was concluded at least for this study there was not a significant difference for response to exercise among the three groups. The conclusion leaves open the question of whether there is a need to teach clients with MVPS differently with regard to exercise. Additional studies are needed to better understand exercise in clients with MVPS. THE DIFFERENCES IN MATERNAL REACTIONS TO INFANTS' SEX BASED ON ATTAINMENT OR NON-ATTAINMENT OF SEX PREFERENCE DURING THE POSTPARTAL PERIOD. Lyn Reilly and Molly Walker, University of Alabama School of Nursing, University of Alabama at Birmingham, UAB Station, Birmingham, Alabama, 35294. Sex preference or the desire to have a child of a particular sex has not been studied in relation to attainment or non-attainment of the desired sexed child. It is believed that non-attainment of sex preference could possibly have negative effects on the development of family relationships. A descriptive design was used to report scores of maternal reaction to the attainment or non-attainment of sex pre¬ ference during the postpartal period. The Maternal Sex Preference Instrument-Postpartum was used to gather data from 115 subjects. This instrument is composed of two parts, a demographic data sheet and a semantic differential scale. Differences in maternal reaction scores between the group of mothers who attained their sex preference and those who did not were found to be statistically significant. Other variables studied included partner's sex preference as perceived by the mother, intentional pregnancy, desire to know fetal sex, sex belief prior to delivery, and methods used for sex selection. It was concluded from this study that mothers had a slightly higher pre¬ ference for male infants especially if it was the first born infant in a family. Subjects also had a definite sex preference and expressed many negative reactions about the sex of the infant when the pre¬ ferred sex was not attained. Further studies are planned to look at the consequences of these negative maternal reactions. 214 Abstracts ASSESSMENT OF ALKYLATION DAMAGE AND REPAIR WITHIN THE MITOCHONDRIAL DNA (MTDNA) OF RINR 38 CELLS. Cathleen C. Pettepher. Susan P. LeDoux and Glenn L. Wilson, Mobile, AL 36688. There is much evidence supporting environmental toxins, like the naturally occurring nitrosourea Streptozotocin (STZ), as causative factors in the etiology of diabetes mellitus. In some cases, this diabetes is associated with altered beta cell function rather than overt beta cell necrosis and more closely resembles type II diabetes. The mechanisms underlying the cellular effects of toxins like STZ have yet to be elucidated. It is known that STZ is a potent alkylating agent of nuclear DNA and most of its resulting lesions are repaired through an excision mechanism. This repair process leads to an intracellular depletion of pyridine nucleotides necessary for cellular respiration with a concomitant drop in ATP concentrations. Since the mitochondrion contains its own genetic information and is the key organelle involved in cellular respiration and generation of ATP, it could be a critical target for the action of STZ. The purpose of these experiments is to determine the extent of DNA damage and its subsequent repair within the mitochondrion, since damage to this organelle could dramatically affect overall cellular function. For these studies, monolayer cultures of Rinr 38 cells were exposed to varying doses (.1-lOmM) of STZ for 1 hour. The drug was removed and the cells were allowed to repair for designated periods of time. The cells were removed, the DNA extracted and digested with Bam HI. After heat denaturation and alkali treatment to cause DNA strand breaks at sites of purine alkylation, the restriction fragments were separated using alkaline gel electrophoresis. Following Southern transfer, the membranes were probed with a 32P-labeled mitochondrial probe. Assessment of alkylation damage and repair was based on the disappearance and the subsequent reappearance of a major restriction fragment over time. It has been previously reported that repair mechanisms do not exist within the mitochondrion. These studies have demonstrated that STZ causes appreciable mtDNA damage in a dose- dependent manner and provide the first evidence that there are mechanisms present within the mitochondrion that repair this damage. ENGINEERING AND COMPUTER SCIENCE IMPLEMENTATION OF PARALLEL BRANCH-AND-BOUND ALGORITHMS ON A SHARED MEMORY MULTIPROCESSOR. Godfrey B. Saldanha & Dr. Alan Sprague, Univ. of Alabama at Birmingham, Dept, of Computer and Information Sciences, AL 35294. In this paper, we explore the feasibility of implementing best first branch-and-bound algorithms on a shared memory multiprocessor, spe¬ cifically on the Sequent Balance 21000. A best-first variant of Little et al's branch-and-bound algorithms to solve the travelling salesman problem ( TSP ), will be used as a testbed for our experiments. The aim of the paper is to make a comparison of the performance obtained by our impleme¬ ntation against that obtained by others( Mohan, Quinn, etc. ) on Hypercu- bic machines. For this purpose, we will be using two parallel implementa¬ tions of the TSP algorithm - one with constant granularity and the other, with granularity increasing with the degree of parallelism. Specific issues to be dealt with, are the Speedup and the number of nodes expanded 215 Abstracts IMPROVED READ'S ALGORITHM. Larry Basenspiler and Sen King, Division o-f Computer and Information Sciences, University o-f South Alabama, Mobile, AL 36688. We describe an algorithm tor calculating the chromatic polynomials of sparse graphs based on that of Ronald Read. Alqorithmic and programming improvements make the space requirement a polynomial function of the size of input and independent of the density of the graph. Because of space constraints, Read's algorithm handles very sparse graphs on up to 15 vertices, and graphs of medium density on up to 10 vertices. Using the constant (10,000 words) amount of space, our algorithm is able to process graphs of any density on up to 32 vertices. We present experimental results of running the algorithm on sparse graphs on up to 26 vertices. The work was partially supported by NSF grant No . ASC- 8900690 . AN APPLICATION OF COGNITIVE MODELING OF COMPETENCY FOR ALGORITHM DEVELOPMENT. John Olson. Herbert E. Longenecker. Jr., and Michael V. Doran. Division of Computer and Information Science, University of South Alabama, Mobile, Alabama, 36688. (205)460-6390. A stimulus will lead to cognition if and only if attention of the observer is gained and the stimulus is recognized. In order to learn a new event, repeated application of the same stimulus must occur so that long term memory will capture the stimulus. Measures for determinig competencey can be based on levels of cognition within a framework of knowledge objects. The following competency levels would reflect the degree of cognition, hence learning: 1 — recognition of facts, 2-- operating with a set of facts, the how and why, 3-- using a set of facts to solve a problem. Repeating a previously learned algorithm is a very different process from devising a new algorithm. With a new algorithm, life cycle techniques must be firmly at hand so that attention can be paid to data and data structures so that a particular sequence of instructions can be devised to transform a given input data set to the requried output It is our hypothesis that in order to learn to write algorithms it is necessary to repeatedly address life cycle stages, the relevance of data and data structures, the translation to hierarchical control structures, the learning of related vocabulary, and the repetative application of this process in succedingly more complex problem domains until the students begin to actively master the process techniques on problems wherein the answers were truly unknown. Learning can not be accomplished without this repetative and spiraling process. These theories were the basis for a series of repetition of our introductory algorithms/problem solving course. Over the span of two years the course has matured, and has remained succesful due to these ideas. Instructors and students of more advanced courses have expressed benefit from this introduction to algorithm development. Advanced students without this background generally do not perform as well. 216 Abstracts AUTOMATABLE PATTERNS IN DEVELOPMENT OF DATABASE APPLICATIONS IN SMALL INFORMATION SYSTEMS. Tariq Ali, Herbert E. Longenecker. Jr., and Michael V. Doran. Division of Computer and Information Science, University of South Alabama, Mobile, Alabama, 36688. (205)460-6390. Higher generation programming languages generate many lines of code in lower generation langauages per line of code in higher generation language. Thus, there are second, third and fourth generations of language. In each generation, higher level function cause increasingly more effect per line of code. Yet, with current fourth generation languages it still requires much code to implement applications. Abstract data types, and object structures are devices for generation of reusuable code. These methods form libraries or tool sets for extensibility of a given programming language. These devices afford ease of use while enabling considerable less error for implementation of what would be described as routine tasks. It is our hypothesis that there are recurrent patterns of code in information systems designs that can be automated by simple specification facilities. Indeed, many lines of code should be replaceable with a single line with parameters that can be used to code generate appropriate sequences in a target fourth generation language. The specification commands may be interspersed within the regular syntax of the fourth generation language giving the feel of a very high level fifth generation language as a result Several business accounting systems coded in the DATAFLEX language were used as objects for the study. Command code sequences were identified in a parsing routine. Commands were expanded using specific processing routines for each particular command sequence. The following sequences were identified for specification and code generation: 1- Scrolling Window Editors and 2~ Update Procedures. In both cases one or two lines of specification could be foound to generate code varying in length according to the parameters giving a code savings of 50 - 200 : 1 depending on the number of fields in the scrolling window, and 15 + n : 1 depending on the number of consecutive fields to be updated. With the update code sequences, a requirement was found to use a similar data dictionary for both source and target files to be updated. FLUE GAS EMISSIONS CONTROL IN SMALL SCALE COAL COMBUSTORS. Nanda L. Mukherjee, Chemical Engineering Dept., Auburn University, AL 36849 CO, total hydrocarbons and particulates emissions from the underfeed retort small scale coal combustors can be reduced econom¬ ically and technically below ERA limit by selecting suitable types of coal and size, modifying screw feeder and retort design, insta¬ lling simple automatic ash discharge system as well as post baghouse CO reduction unit in the combustor and optimizing combustion process. S0X emission in flue gas can be decreased 75-80% of the normal level by employing low sulfur coal mixed with CaO. At the same time combustion efficiency could also be increased significantly. 217 Abstracts USE OF EXPERT SYSTEM TECHNOLOGY TO MODEL PROBABILITIES OF DISORDERS IN PEDIGREE ANALYSIS. Charles Gamer. Michael V. Doran, and Herbert E. Longenecker, Jr.. Division of Computer and Information Science, University of South Alabama, Mobile, Alabama, 36688. (205)460-6390. A pedigree is a graphical hierarchical representation of family relationships. Viewed from the child's perspective backwards, the pedigree is a tree structure. However, matings of individuals can involve cyclic relations which can not be modeled hierarchically. Previous models of pedigrees have been attempted with limited degrees of success. Some models use only tree drawings. Others have used a textual database format, but have lacked a graphical interface and presentation methodology. We have described a system which allows the graphical and textual creation, modification and manipulation of the pedigree. This is accomplished via a reversible data structure which allows for a transformation between nodal elements for graphical, editing and storage purposes. It is our hypothesis that a rule-based system can be developed to perform analysis of human pedigree structures. This analysis is accomplished by the use and understanding of the knowledge inherent in the pedigree chart. Traits occur in a family with a known degree of probablity. An automated tool would assist in such analysis and better allow for predication of future disorders. A network model was selected for the storage structure for pedigree information. Each node within the network represents a mating of two individuals who have in fact produced progeny related to the mating. Multiple progeny may be stored in relation to the same parent set. Multiple attributes of individuals are stored in a related structure which is tied to each mating in which that individual is involved. These attributes include specific knowledge of the genetic traits or other physical findings. By initial complete ancestral traversal, all known traits are posted on nodes of the data structure. By subsequent ancestral traversal specific occurrences and/or future conditions may be calculated and predicted. This method works with cyclic mating behaviors. Simple heuristics may be employed to fill in missing data items by forward or backward referencing dependent of available facts or suppositions. Implementing an Ada-to-Parallel C Translator. Subramanian Varadarajan. Dept, of Computer and Information Sciences, University of Alabama at Birmingham, Birmingham, AL 35294. A compiler for Ada to produce parallel code can be implemented by exploiting the parallelism in the tasking features of Ada. The host system for the compiler under construction is a Sequent Balance 21000 which is a 30-processor bus-connected MIMD architecture. The use of several processors available in the Sequent makes possible the efficient exploitation of heterogeneous parallelism found in the multi-tasking features of Ada. This is implemented by doing a source-to-source translation of an input Ada program to its equivalent code in C. The system routines available in DYNIX (a parallel version of UNIX on the Sequent) can be invoked from the output program in C, to implement multi-tasking on the available multiple processors. The output code may then be compiled using an existing parallel C compiler. Acknowledgements: Foremost, I would like to thank my advisor, Dr. Barrett R. Bryant for his detailed comments and suggestions to improve this project. I also thank the Department of Computer and Information Sciences, UAB for giving me a pleasant working environment. * Ada is a registered trademark of the United States Department of Defense, Ada Joint Program Office. 218 Abstracts ON-LINE EXPANSION OF DATA DICTIONARIES IN A GRAPHICAL ALGORITHM DEVELOPMENT ENVIRONMENT. Ser Seong Lee, Michael V. Doran, and Herbert E. Longenecker, Jr.. Division of Computer and Information Science, University of South Alabama, Mobile, Alabama, 36688. (205) 460-6390. In conventional flow charting or hierarchy charting methods, data and data flows are not presented. With data flow drawings, there are alternate possible implementations of the data flow, and there is no committment to a particular or even exact solution. CASE tools such as Excelerator capture the current state of methodologies of defining data flow and data dictionaries, and allow drawing of control flow based on the identified data flows. The level of detail of the actual data transformations are not evident As the complexity of the data structures increase, data flow drawings become less meaningful without some drawing showing the details of the data structures. It is our hypothesis that computer assisted design environments require methods to define and present data structures and data flows during the process of algorithm development. That is, design must be based on data and data flows, and that without adequate representation of data and data flows, design may be flawed or difficult. We have used the concepts of defining data within the context of a graphical hierarchical structure chart development environment. Data is defined and recorded in data dictionaries. These dictionaries become visible as each task, or process is instantiated. During the development phase, the dictionaries are created or modified. Subsequently, the graphical structures are directly executed. This allows for immediate feedback and validation of the developed algorithm vis a vis the correctness of data generated by the process as viewed in the data dictionaries. In this method, data flows are replaced by the concept of sequential data dictionaries. Also, parameters are specific data dictionaries that are drawn prior to the execution of a procedure, as opposed to any other valid instruction. At any level within the chart, all data, and data flows must always be in balance from the input to the eventual output of the algorithm. Support from the USARC grant is gratefully acknowledged. THE EFFECT OF OZONE ON COAGULATION OF COLLOIDAL CLAY PARTICLES IN DRINKING WATER TREATMENT PROCESSES . George P. Whittle, Dept . of Civil Engineering, Univ. of Ala., Tuscaloosa, AL 35487. Rickey B. Harrison, Hankins and Harrison Engineering, Inc., Tuscaloosa, AL 35401. The effect of ozone on coagulation/clarification water treatment processes was studied by subjecting raw- water samples containing colloidal-clay turbidity to treatment with ozone in a laboratory jartest procedure. Samples were dosed with varying amounts of ozone followed by addition of alum and lime in a treatment— step sequence of rapid mix, slow mix, sedimentation, and filtration. Turbidity removal efficiencies, zeta potential measurements, and required sedimentation times obtained on ozonated samples were compared with those obtained on unozonated samples. Turbidity removal efficiencies were found to be higher in ozonated samples, and low doses of ozone produced a significant reduction in zeta potential. On ozonated samples, the sedimentation time required for a given turbidity removal was found to be less than that required for unozonated samples. It is postulated that low doses of ozone change the chemical character of adsorbed organic matter on the clay surface resluting in a reduced zeta potential at the surface of shear, and higher dosages of ozone strip away the adsorbed organic layer producing a "clean-surface" state amenable to an improved agglomeration when a coagulant is added. 219 Abstracts PRACTICABLE HYDROLOGIC CONSIDERATIONS FOR HYDRAULIC DESIGNS IN ALABAMA. Jay K. Lindly, James V. Walters, Daniel S. Turner, and David K. Hains, Dept, of Civil Engineering, Univ. Of Ala, . Tuscaloosa AL 35487-0205 . Hydrologic aspects of the design of hydraulic facilities for stormwater management in Alabama are worthy of careful, detailed considerations that will lead to designs conforming to high performance standards. Damages and liabilities associable with some relatively recent designs economically demand those considerations. Practioners should devote effort to the design of the convenience system of drainage facilities to minimize flooding nuisance as they have in the past. They also must consider the convenience system and how it will function as a part of the major drainage system of an area during the occurrence of major storm events whose annual likelihoods of occurrence are smaller than ten percent. Designers must select the appropriate storm recurrence interval for their application, and then they must have access to storm intensity, duration, and frequency data for their particular location within the state. The rainfall data for use in such designs are available in broad form from applicable National Weather Service, National Oceanic and Atmospheric Administration studies. The authors used raw data and algorithms supplied in those studies to develop intensity-frequency-duration rainfall data for ten Alabama cities selected to cover the state. THE CRITICAL ROLE OF DATA FOR NOVICE STUDENT ALGORITHM DEVELOPMENT, UNDERSTANDING AND VERIFICATION. Michael V. Doran, and Herbert E. Longenecker, Jr. Division of Computer and Information Sciences, University of South Alabama, Mobile, Alabama 36688. (205)460-6390. In many programs in computer science utilizing the ACM CS1, and CS2 sequences (Curriculum 78) a primary focus in on computer language elements and syntax. Frequently design is often not addressed, or design are handed to students. Student code production is rarely based on a reproducible software life cycle methodoloogy. Rather, the students leam to "hack" code, that is, to produce code in an irrational and ad hoc uncontrolled manner. Several approaches to algorithm development have been used over the past several years with varing degrees of success. The initial method was a purly abstract approach using pseudocode with complex problems, with little or no emphasis placed on data or data structures. This method resulted in a high level of student failure. It is our hypothesis that novice students should be exposed to software engineering principles in the initial course in a computer science sequence. This will build a proper foundation for problem solving to be used in later courses, and fosters the notion that knowledge of data structures, is prerequisite to algorithm development. We have designed a course to address all of these issues: 1-- Data structures are defined, drawn, and are represented in data dictionaries during the requirements phase, 2- Control flows are graphically and systemstically developed based upon the data flows, 3— The complexity of each problem is kept to a minimum so that each new concept is presented and utillized in a sequential and orderly fashion with immediate feedback to the students given using an automatic graphical algorithm language in which flows of control are indicated by shapes, and are converted automatically to Pascal code which is executed by Dr. Pascal (Visible Software, Inc.). High success rates have accompanied this approach as evidenced by a considerably lower course drop rate and higher performance on course exams. 220 Abstracts “Think-Time” Awareness in Scheduling. Robert A. Allen, Department of Computer Science, The University of Alabama, Tuscaloosa, Alabama 35487-0290. Classical computer scheduling algorithms make decisions based upon the as¬ sumption that all iisers’ response time needs are equivalent. “Fair and equitable” response times are desirable, however, each user may actually perform better un¬ der his own uniquely characterized virtual system. Virtual system characterizations should change dynamically as each user not only changes from task to task but as each user begins to fatigue. It would appear advantageous for an Operating System to individually cater these user/task dependent virtual system characteri¬ zations to each user. One system measurable user characteristic which should be a critical component of a uniquely characterized virtual system is the user’s think¬ time. “Think-Time Oriented” CPU scheduling algorithms have been developed as a first, step to incorporate user’s think-times and user’s needs into each user’s vir¬ tual system. System resources should be proportionally distributed among its users based upon the users’ performance needs. It has been shown that users overlap different amounts of think-time with processing time as a function of task. There¬ fore, user’s response time needs change from task to task. Think-time oriented scheduling algorithms dynamically adjust to reflect current user think-time behav¬ ior. Think-time algorithms have been developed as non-preemptive CPU scheduling algorithms. Extension of these think-time oriented scheduling algorithms to include preemptive CPU scheduling and the scheduling of other resources is now at hand. Other resources of interest include main memory and disk drives. As Operating System designers, we must keep in mind that we are scheduling more that a piece of hardware. Every scheduling decision which is made in our operating system trinkles down to our end users. Users then make their own scheduling decisions based upon what they have “seen” or experienced on our systems. Different perceptions of the system a, re, on an individual basis, more conducive to productive work than others. System designers’ goal should now be to learn how to give each user the system which, subject to physical constraints, makes that user tne most productive at his task. Our users’ success is the ultimate measure of our system’s success. HYDRAULIC OCMXtCITVITY OF CLAYS USING HIGH HYDRAULIC GRADIENTS, Norman D. Pumphrev. Jr. . Department of Civil Engineering, University of Alabama, Tuscaloosa, AL 35487. Hydraulic conductivity of a clay soil is a particularly troublesome characteristic to determine using standard laboratory or fieldj^ests. A typical clay soil might have a hydraulic conductivity of 10 7 centimeters per second or less. Under normal hydraulic gradients present in the field, it can take months or even years for a fluid to permeate through a 1" clay layer. High hydraulic gradients might be used to decrease the time required for the fluid to permeate through the soil. Unfortunately , these high gradients can cause problems which prohibit the accurate measurement of the hydraulic conductivity. Particle migration and decreased void ratio under extreme pressures will cause measured values to be significantly less than the conductivity values present under normal field conditions. System and border leaks, which are often difficult to detect, can cause measured conductivities to be greater than the field values. These potential measurement errors can have serious implications in the area of hazardous waste containment using clay liners. A conductivity measurement error of one magnitude could cause a liner designed for a 100-year life to fail after only 10 years. As a result, high hydraulic gradient tests should only be used to find relative instead of absolute hydraulic conductivity values. 221 Abstracts ANALYTICAL REPRESENTATIONS FOR THE THERMAL CREEP OF A NUCLEAR FUSION REACTOR FIRST WALL ALLOY. Gladius Lewis, Dept, of Mechanical Engineer¬ ing, Memphis State University, Memphis, TN 38152. Selection of the proper material for structural components of the first wall is arguably one of the most pressing issues in the evolution of nuclear fusion reactors. Thus, interest in and study of this aspect is justifiable. In the present work, .the focus is on the thermal creep deformation behavior of one material, HT-9 ferritic steel, with a view to presenting appropriate empirical parametric relations for this de¬ formation. HT-9 steel would probably be the material of choice for the first wall of a commercial reactor, and has thus attracted a lot of re¬ search and development attention in recent years. Essentially, the approach taken involves obtaining relations that describe the depen¬ dence of creep strain, e , on time, t, temperature, T, and stress, (T , taken severally or jointly. The selection of empirical relations to examine was guided by a study of the literature which indicated which relations have been most frequently shown to reasonably describe the creep deformation of a variety of ferrous materials. For each equa¬ tion, the procedure for extracting the values of the empirical coeffi¬ cients from the experimental e - t data (which had been obtained pre¬ viously at three combinations of stress and temperature) involves the use of a nonlinear parametric estimation technique, namely a guarded Gauss - Newton method. Using the criterion of the standard error of estimate of the creep strain, the equation that provides the most accurate representation of the data is obtained. Finally, a description of the thermal creep mechanism of the alloy, based on the results of the study, is presented. A MULTILAYERED NEURAL NETWORK FOR ROTATIONAL INVARIANT PATTERN RECOGNITION. Ramiah Srinivasan, Dept, of Computer&Information Sciences, University of Alabama at Birmingham, AL-35294. Most pattern recognition techniques, especially template matching, are over sensi¬ tive to shifts in position of the pattern. These techniques, as a result of the above stated downfall, find very little practical application. This has led many researchers to look for pattern recognition algorithms which would tolerate shifts in position, rotations and also distortion and noise. Cognitron is an algorithm proposed by Fukushima of NHK Labs in Japan.This algo¬ rithm is based on the structure of the visual nervous system and can be realized with a multilayered network containing neuron like cells. The algorithm is such that the network acquires the ability to recognize patterns through unsupervised learning (ie. self organization without a teacher) depend¬ ing only on the shapes of the characters. This algorithm has been modified in this paper by moving it from Unsupervised learning to supervised learning paradigm. Backpropagation is used as the learning algorithm. This network at present is capable of rotational invariant pattern recognition.

Tel: (205)-934-2213 A special natural language parsing technique is used on an object-oriented data-base system called ASASA (A System to Assist School Applications). The goal of the data-base system is to help the applicants to choose suitable schools for themselves in a short time and in a convenient way. The user can use the natural English to communicate with the system and the system is built for people who have little or no computer science background. The major functions of the system are: 1. INQUIRE: The user can ask for any information related to the university applications; 2. CONSULT: The system can work as a consultant and even answer personal questions of the users and guide them to the best choice; and 3. CREATE. The user and the system administrator can add any updated information to the system using English and the system itself also has a self-learning function. The parsing technique that we use is based on dynamic accessing of keywords in the syntactic structure which omits the tedious formal syntax parsing of natural languages. The advantages of this technique are high efficiency and allowing the user to use a wide range of English structures even including those with grammatical mistakes. Furthermore, it works especially well with the object-oriented database system because the keywords are organized in an object-oriented style. This system has been implemented on the VAX system in LISP. Acknowledgement. This research has been supported in part by a student research grant from the Alabama Academy of Science. ANTHROPOLOGY ALBUMIN VARIANTS AMONG NATIVE AMERICAN POPULATIONS. Kenneth R. Turner , Dept, of Anthropology, Univ. of Ala., Box 870210, Tuscaloosa, AL, 35487-0210. Among Native American populations, polymorphic frequencies are attained by two serum albumin variants: albumin Naskapi and albumin Mexico. Albumin Naskapi occurs at relatively high frequencies among populations belonging to the Athabascan language group and is found very rarely in other North American populations. Albumin Mexico is found at relatively high frequencies among several populations from Central America to the southwestern United States, and rarely elsewhere. Surveys of these albumin variants have neglected regional ethnohistoric human biology and have consequently been so population-specific as to obscure significant patterns. Ethnohistoric reconstructions organize the jumbled mosaic of data and reveal previously unseen implications in distributions of these two albumin variants. 223 Abstracts A DESKTOP COMPUTER SIMULATION FOR ANTHROPOLOGY. Mark A. Andrews and Kenneth R. Turner, Dept, of Anthropology, Univ. of Ala., Box 870210, Tuscaloosa, AL, 35487-0210. POPLAB, a Pascal program authored by Mark A. Andrews for IBM compatible microcomputers, simulates human populations for anthropol¬ ogical teaching and research. POPLAB determines the framework accord¬ ing to user-specified conditions. Students select one of several predefined initial populations or create their own, selection age- specific mortality and fertility rates, and specifying mutation and selection coefficients. For experiments of anthropological interest, students can vary incest rules, other rules of mate selection, birth intervals, ideal family sizes, and other conditions. POPLAB demon¬ strates the principles of population genetics and their importance to anthropology by presenting a laboratory-like opportunity to experiment upon simulated human populations. AN ARCHAEOLOGICAL SITE INVENTORY OF LAKE OKATIBBEE, MISSISSIPPI. Trov 0. Martin. Panamerican Consultants, Inc. P.O.Box 050623 Tuscaloosa, Alabama 35405. Beginning in the summer and continuing in the winter of 1989, Panamer¬ ican Consultants, Inc., under contract to the US Corps of Engineers, Mobile District, performed a cultural resources survey of Lake Okatib- bee , Ms. The purpose of this survey was to provide an archaeological site inventory for the Corps, listing all aboriginal sites within the Corps property in the lake area. During the conduct of this survey a total of seventy-nine archaeological sites of aboriginal origin were discovered, dating largely from the Archaic and Woodland Stages. EXCAVATION AT BLUE HOLE WEST SITE lCak21. Harry 0. Holstein and Curtis E. Hill, Archaeology Resourse Laboratory, Jacksonville State University, Jacksonville, AL 36265. The Blue Hole West Site, lCaU21, lies approximately 91 meters (300 feet) west of a large natural sinkhole spring adjacent to Cane Creek north of the City of Anniston, Alabama. In the spring of 1989, a total of fifty-three subsurface excavation units were excavated revealing thirty-eight aboriginal features and one hundred twenty-nine postmolds. The features and postmolds confirm the presence of a Woodland (Coker Ford and Yancey's Bend Phase) Village with associated ceremonial mound . 224 Abstracts MICROSCOPIC USE WEAR ANALYSIS OF FLINTS FROM THE ANCIENT CITY OF MEM¬ PHIS, EGYPT. Michael A. Kittrell , Dept, of Anthropology, Univ. of Ala. , University, AL 35486 During the 1985 field season excavation within the ancient 18 th- 19th dynasty city of Memphis, Egypt, located along the Nile River just south of present day Cairo, an assemblage of over one hundred large flake tools manufactured from local Egyptian flint was unearthed. The flint tools were found in the context of a single floor level within a domestic structure. With the use of stereoscopic and incident light microscopes, traces of utilization including microscopic edge damage, striations, and polish become apparent at magnifications of lOOx to 400x, Preliminary analysis of a portion of the assemblage by Dr. Boyce Driskell in 1986 suggest their use as impromptu butchering tools. Similar analysis of the remainder of the assemblage is ongoing at the Division of Archaeology, Alabama State Museum of Natural History.

Linda Derry, Alabama Historical Commission, 719 Tremont St., Selma, AL 36701 The research design for Old Cahawba centers on the theory that the material world is manipulated to signal incorporation or exclusion from groups. Instead of trying to explain discovered archaeological patterning with the usual simplistic, externally imposed categories of economics, politics, etc., we undertook documentary research prior to excavation in order to approximate the groupings that were actually important within the 19th century community. Preliminary findings indicate that identification with kin was much stronger than with status defined by wealth. Previous historical studies have described our research area as lacking any supportive kin net¬ works, but this work suffers from strong androcentric bias. In fact, women, especially married sisters, were the social glue that bound together rootless young men who were traveling west to seek their fortunes. Identification with wife's kin will be shown in examples of "action-statements," clustering of architectural styles, spatial ordering of residential lots, and in the composition of cemetery plots. Finally, predictions about how these alliances will be reflected in the archaeological record are presented. THE ALABAMA SUBMERGED CULTURAL RESOURCES (SCR) SITE FILE: A PROGRESS REPORT. Brina J. Agranat. Department of History, Univ. of Ala., Tuscaloosa, AL 35487. In 1989 the Division of Archeology, University of Alabama, initiated a five-year program to develop a computerized Submerged Cultural Resources (SCR) Site File for the State of Alabama under a grant from the Alabama Historical Commission. During Phase I, 391 shipwrecks and 39 non-shipwreck sites were input into the dBase III file, representing a preliminary inventory of known or recorded sites within the Tombigbee, Black Warrior, Mobile, and Alabama River Systems, and Mobile Bay (including Mississippi Sound and offshore waters). Phase II of the project, in progress, expands this preliminary inventory to all navigable waters within the State of Alabama. In addition to the dBase III file, the SCR Site File is also being developed into a fully integrated Geographic Information System (GIS) , utilizing the University of Alabama Remote Sensing Laboratory's Intergraph system. Once complete, the GIS will maintain important geographic data, including survev areas, river and harbor improvements, dredge and disposal areas, and recorded anomalies, as well as known site locations. 226 Abstracts ARCHAEOLOGICAL MITIGATION OF ADVERSE IMPACT FROM HOUSE RECONSTRUCTION AT THE MCINTOSH RESERVE, CARROLL COUNTY, GEORGIA. Catherine E. Clinton and Tim S. Mistovich, Panamerican Consultants, Inc., P.O. Box 050623, Tuscaloosa, Alabama 35405. The McIntosh site ( WGC13 ) is located on the McIntosh Reserve, Carroll County, Georgia. It has long been thought to be the location of General William McIntosh's plantation residence - Lochchau Talofau. General McIntosh was a prominent early nineteenth century leader among the Lower Creek Indians and was infamous for his part in negotiating Indian land cessions in the 1810s. Because of his role in these negotiations, McIntosh was murdered in 1825 at Lochchau Talofau by hostile Upper Creeks. In addition, McIntosh's home, a large two-story log structure, and several outbuildings were burned. Although a DAR-erected grave monument was placed at the site in the early 1900s, the exact location of Lochchau Talofau has never been identified conclusively. However, inferential evidence has been unearthed which suggests that WGC13 is, indeed, the site of the McIntosh plantation. THE PICKWICK BASIN CAVES PROJECT: ACCOMPLISHMENTS AND PROSPECTS. Boyce N. Driskell , Division of Archaeology, Alabama State Museum of Natural History, University of Alabama, University, AL 35486 The Museum, with support from the Tennessee Valley Authority and in conjunction with the University of North Alabama, is conducting archaeological investigations within Coffee Slough near Florence, Alabama. In places, the karstic bluff line towers up to 100 feet above waters of the slough and numerous caves occur within its sheer face. Thus far, only Smith Bottom Cave has been extensively excavated: in other caves, explorations have been limited to small test excavations. Even so, it is already clear that several caves along this bluffline were used by prehistoric peoples as burial repositories while other caves were used for habitation or special activity areas. The re¬ search will continue in the summer of 1990 with extensive excavation of Dust Cave. Preliminary testing revealed the presence of middle Archaic deposits overlain with a layer of natural cave fill. Up to three meters of archaeological deposits may be present within the initial room of the cave; other areas of the cave are yet to be ex¬ plored. Eventually, these archaeological explorations in the Pick¬ wick Basin will add substantially to our understanding of the use of caves by the prehistoric inhabitants of the Tennessee Valley. 227 MINUTES ALABAMA ACADEMY OF SCIENCE ANNUAL BUSINESS MEETING Stouffer's Riverview Plaza Mobile, Alabama March 9-12, 1990 1.

This subspecies is one of three occurring along the Gulf Coast that are listed as endangered by the U.S. Fish and Wildlife Service. Eight subspecies of the oldfield mouse, which inhabits a wide range in southeastern United States, are restricted to coastal beach dune habitat and are collectively known as beach mice. They are lighter in color than inland forms, with areas of white pelage on the face and a reduction or loss of the tail stripe. Beach mice have been reduced to small, isolated populations as a result of extensive development along coastal Alabama and Florida. Tropical storms and hurricanes represent the greatest threat to loss of remaining populations. Beach mice are currently being intensively studied by personnel of the Alabama Cooperative Fish and Wildlife Research Unit at Auburn University. Photograph courtesy of Dr. Nicholas R. Holler.

So-called "Squamiform load oasts" (actually flutes) and associated grooves are indicators of deepwater deposit Lori. Interpretation of these structures as flute marks, and not as load casts, was suggested by John E. Sanders. This distinction is important, because load casts are not primary features, but form after deposition of sand over mud, whereas flute marks are current structures formed in mud and then preserved by later-deposited sand.

Kopaska-Merkel Geological Survey of Alabama P. 0. Box 0 Tuscaloosa , AL 35486-9780 and Jonathan Grannis Phillips Petroleum Resources Limited 1 44 Fourth Ave. Southwest Calgary, Alberta T2P3N4 Canada ABSTRACT Sedimentary structures from the Middle Cambrian Whirlwind Formation of Utah are interpreted as wrinkle marks (sedimentary structures formed under very shallow water conditions) . The absence of ripple cross lamina¬ tion, fine particle size of the rock, small size of the structures, and the presence of disturbed relict lamination in wrinkle-marked samples support this interpretation. Previous workers* have described and in¬ terpreted the surface morphology of wrinkle marks; internal structures described in this paper provide additional criteria for their identifi¬ cation. INTRODUCTION Wrinkle marks, or ru nzelmarken , are small-scale, ripple-like, bedding-plane features generally associated with tidal and peritidal deposits (Allen, 1984, 1985; Reineck and Singh, 1980; Reineck, 1969). These structures are believed to form through the action of wind-driven, non— erosive shear by a thin film of water on underlying fine-sandy or silty sediment (Reineck, 1969) . The steep sides of asymmetrical wrinkle- mark crests face away from the direction of applied stress. Wrinkle marks are sensitive indicators of intermittent emergence of the sediment surface (Reineck and Singh, 1980), so a reliable means of identification and an understanding of their origin and structure would be helpful to research¬ ers studying shallow-water deposits. This would allow corroboration of conclusions based on other sedimentary structures and lithologic associ¬ ations. In this paper, the internal structure of sedimentary features interpreted as wrinkle marks is described in order to facilitate wrinkle- mark identification and to provide cross-sectional information for interpretations of wrinkle-mark origins. Sedimentary structures interpreted as wrinkle marks in Middle Cambrian rocks of Utah display previously unreported features that are consistent with the mode of origin proposed by Reineck (1969).

More precise location information and stratigraphic sections showing the occurrences of wrinkle marks appear in Kopaska-Merkel (1983, 1987, especially his figures 2, 3, and 6) . features may facilitate the discrimination of wrinkle marks from other sedimentary structures. The wrinkle marks, collected from several strati¬ graphic sections in the Drum Mountains (Fig. 1) , were associated with desiccation cracks and flat-pebble conglomerates. They are preserved in calcareous siltstone in the Whirlwind Formation, a shallow subtidal and peritidal deposit (Kopaska-Merkel, 1983, 1987). DESCRIPTION Height of individual wrinkle marks in the Whirlwind ranges from 1 to 2 mm; spacing from 5 to 9 mm. Wrinkle marks are dominantly asymmetric with most steeper sides facing in a common direction (Fig. 2). Transverse crest lengths average about 50 mm; the longest continuous crest observed was 100 mm. Individual crests are generally subparallel. Poorly- to well-defined bifurcations of the crests occur at irregular intervals. 237 Detailed Structure of Wrinkle Marks Fig. 2. Plan view of wrinkle -marked sample; shadowed faces are, on the average, steeper. Scale in cm. Internally, the wrinkle marks are not ripple cross laminated (Figs. 3 and 4). The thin (15 mm) bed upon which they occur consists of a lower, parallel- laminated division and an upper division (2.5 to 5.0 mm thick) that is in part structureless and in part shows discontinuous lamination like that in the lower division. The boundary between the two divisions is, in most places, parallel to bedding (Figs. 3 and 4). Wrinkle-mark troughs lie from 1.5 to 3.0 mm above this horizontal boundary; the wrinkle marks are therefore rooted within the upper (disrupted) division. In the upper division, some laminae dip away from the inferred direction of applied stress; others form symmetrical ripple-like forms. These are out of phase with the surface form of the wrinkle marks but are of similar amplitude and spacing (Fig. 3). The origin of the symmetrical ripple-like laminae is unknown, but they may be primary laminae deformed by the shear stress that formed the wrinkle marks. 238 Kopaska-Merkel and Grannis B Fig. 3.

In figure 3, a horizontal plane is the only boundary between the deformed and nonde formed divisions. 240 Kopaska-Merkel and Grannis Wrinkle marks sometimes display small bumps or kinks averaging 0.15 mm in amplitude and distributed in a regular pattern along their upper surfaces (Figs. 3 and 4). They differ from the wrinkle marks on which they are superimposed primarily in having a smaller spacing and lesser amplitude. These kinks may be second- order deformational features ap¬ parently formed as a quasi -periodic response to the same lateral shear force that produced the wrinkles. Alternatively, the kinks could be smaller- scale features generated by shear before the wrinkle marks formed. DISCUSSION The absence of any cross laminae, the occurrence in some wrinkle marks of internal laminar features that are not cross laminae, the small scale of the structures-, and the fine- textured nature of the rock make it unlikely that the wrinkle marks were formed by depositional sedimentary processes. The mean particle size of the rock is about 0.1 mm; this is near the minimum size known to be transported as bedload (Mantz, 1978). Minimum reported height for wave or current ripples is 3 mm (Reineck and Singh, 1980), a millimeter or more greater than the maximum height of the wrinkle marks described here. (Mechanical compaction of this rock was negligible because it contains very little clay.) Although the wrinkle marks in the Whirlwind Formation have only been found on weathered surfaces, it is unlikely that they are the product of modem subaerial weathering. The very regular areal pattern of ridges, roughly constant ridge height and trough depth, and gently rounded ridge - and trough cross sections do not support a weathering origin. More tellingly, linear dissolutional or erosional features commonly show a dendritic areal pattern not observed in inferred wrinkle marks from the Whirlwind Formation. Also, it appears that wrinkle ridges rise above the undisturbed sediment surface adjacent to the wrinkle marks in figure 2; this would not be the case if the features had resulted from weathering. Wrinkle marks occur only on bedding surfaces; weathering features might also be expected on the joint surfaces which are common in the Whirlwind Formation. Finally, unequivocal weathered rock surfaces in the Whirlwind Formation in the Drum Mountains exhibit "razor-blade topography" and other typical weathering features, but nothing resembling wrinkle marks. Wrinkle marks from the Whirlwind Formation show similarities to ancient wrinkle marks described and/or figured by other authors, and are similar to recent marks figured by Reineck (1969, Fig. 2) but have slightly greater amplitudes. They are comparable to those produced experimentally by Reineck (1969, Fig. 3) but differ in that the natural crests are more rounded, and the smaller transverse crests present in experimentally formed wrinkle marks are absent. Wrinkle marks figured by Reineck and Singh (1980, Fig. 80), unlike those described here, have a honey-comb-like arrangement of crests; they are also continuous on a much smaller scale. Hunter (1969) figured several examples of ancient microridges (ad¬ hesion ripples) that he suggested might be of aeolian origin and that look almost identical to wrinkle marks described in this paper. Hunter at- 241 Detailed Structure of Wrinkle Marks tributed these ancient marks to the adhesion of dry sand on a wet sandy surface, but Teichert (1970) suggested that they may be wrinkle marks. The features described by Hunter and those described in this paper are quite similar in external form, but internal structure appears to be very different (Hunter, 1973). At least some adhesion ripples are internally pseudo-cross laminated (Hunter, 1973). With one exception, wrinkle marks described in the literature have been found in deposits interpreted to have formed in shallow water where intermittent exposure of the sediment was possible. The exception was described by Dzulynski and Simpson (1966). The structures they described were associated with features typical of flysch, and are unlikely to have formed in shallow water. This indicates that wrinkle marks should not be used alone as environmental indicators, but are best considered within the context of an association of sedimentary structures. Comparison of wrinkle marks described herein with other published descriptions indicates that a range of surface morphology of these structures exists. The internal structure of wrinkle marks may also be highly variable but this is not known. Variations in morphology probably reflect variations in the conditions that prevailed during formation of the wrinkle-mark assemblages. Differences in water depth, wind veloc¬ ities, particle sizes, and cohesiveness and water content of the sediment are factors which may influence the form and distribution of wrinkle marks. Reineck (1969) reported that experimental wrinkle marks are smaller when formed in shallower water. Particle size, cohesiveness, and water content of the sediment probably affect the angle of repose and therefore the final slopes of wrinkle marks. The probable effect of wind velocities is unknown and should be investigated experimentally. CONCLUSIONS The absence of ripple cross lamination, the small size of the structures, and the fine particle size of the rock indicate that the wrinkle marks in the Whirlwind Formation were not formed by primary depositional processes. The zone of detachment and overlying wrinkled division imply deformation of a continuous layer of sediment as a unit. The small superimposed kinks and possible upward stepping of the shear surface (Fig. 4) also indicate a syndepositional deformational origin for the wrinkle marks. The dominantly asymmetric profiles of the wrinkle marks indicate unidirectional stress (i.e., a single, clearly dominant wind direction) . All these features suggest that these wrinkle marks were formed by the action of non-erosive, horizontally-directed shear stress upon an unlithified or semilithif ied cohesive sediment surface.

SEASONAL AVAILABILITY OF GOPHER TORTOISE ( GOPHERUS POLYPHEMUS ) FORAGE IN SOUTHWESTERN ALABAMA1 • 2 John E. Marshall and Judy P . Stout Department of Biological Sciences University of South Alabama Mobile, AL 36688 ABSTRACT Seasonal forage availability was investigated in two colonies of gopher tortoises ( Gopherus polyphemus ) in southwestern Alabama. Grasses were the dominant forage type of both sites, but legumes were more abun¬ dant at the site that experienced prescribed bums on a regular basis. Both the quantity and quality of gopher tortoise forage appears to be related to the frequency of fire. INTRODUCTION The gopher tortoise, Gopherus polyphemus (Daudin 1802) (Testudines: Testudinidae) is a colonial species that inhabits xeric plant communities of the Coastal Plain of the southeastern United States. (Conan t 1975, Mount 1975). Tortoise habitat, in most of 'its range, is typically char¬ acterized by deep, well-drained sandy soils and a canopy dominated by longleaf pine ( Pinus palustris ) (Auffenberg and Iverson 1979, Landers and Speake 1980). These "sandhills" plant communities have been historically maintained in an open, park-like condition by periodic fires (Komarek 1974, Lohoefener and Lohmeier 1984, MacDonald and Mushinsky 1988). As one of the principle grazers of the sandhills ecosystem, tor¬ toises are heavily dependent upon the availability of herbaceous ground cover. Tortoise population densities have been closely correlated with both the quality and quantity of ground cover (Garner and Landers 1981, Landers and Speake 1980) . The dispersal of tortoises from centers of activity has also been associated with the availability of forage (McRae, et al. 1981). The availability of preferred foods may change between seasons, which in turn may cause variations in population densities and dispersal patterns of tortoises. The purpose of this study was to examine the seasonal availability of forage at two different sites and to address some of the factors which may have affected it. Special emphasis was given to legumes (Fabaceae) , because of their potential nutritional importance to tortoises (Garner and Landers 1981) .

This is a 259-ha site located along Girby Road, 2.1 km west of U.S. Highway 90, in central Mobile County, Alabama (Figure 1) . The ESC is composed primarily of upland xeric forests characteristic of the Southeastern Coastal Plain sandhills (Mount 1975, Lelong 1977) . Tree cover is dominated by longleaf pine and oaks (Quercus spp.). Understory vegetation consists primarily of grasses (Poaceae) , forbs, blueberries ( Vaccinium spp.), and greenbrier ( Smilax spp.). The canopy was relatively open due to blow— down of numerous large trees by Hurricane Frederick in 1979 and timber harvesting conducted prior to 1974 (L. Scott, Pers . comm..). Fire had been absent from this site for many years as evidenced by the dense stands of seedling and sapling stage trees and encroaching shrubs. The principle soil types in the xeric habitats were Troup loamy sand and Troup-Heidel Complex, with slopes of 0- 12% (Hickman and Owens 1980) . The tortoise burrows were located in both soil types on two sand ridges, which were separated by a small stream. Study Area 2 was a 486-ha tract on private land owned by Arthur Tonsmeire, Jr. (TP). This tract is bounded by the Dog River, Rangeline Road, and Alabama Highway 163A in southeastern Mobile County (Figure 1) . It consists primarily of moist pinelands dominated by longleaf pine and pitcher plants ( Sarracenia spp.). The tortoise colony was located within a relatively narrow strip of land running from east to west, and bisected by a small stream. The plant community within this strip was a longleaf pine-turkey oak (Quercus laevis) association. Soils were Escambia sandy loam with 0—2% slopes and Troup loamy sand with 0—5% slopes (Hickman and Owens 1980) . Tortoise burrows were found almost exclusively in the latter soil type. The TP site was managed for longleaf pine and bobwhite quail (Colinus virginianus) . Timber was harvested by selective cutting and periodic prescribed buring was employed as a management tool for natural regeneration of pine and habitat improvement for quail. Most of the gopher tortoise habitat was burned the winter prior to this study. METHOD Vegetation was sampled in 1984, between March and October. Ground cover was sampled in early spring and later summer at the ESC and later spring-early summer and later summer at the TP site. Canopy cover at both sites was sampled in late summer. Tortoise burrows were located using a variety of survey techniques (Marshall 1987). All burrows were flagged and assigned a number with the prefix "B", in the order in which they were discovered. Ground cover was clipped around 3 randomly selected burrows (B-l, B- 6, B-ll) at the ESC and around four randomly selected burrows (B-9, B-14, B-12, B-21) at the TP site. The sampling scheme was similar to the point- 245 Seasonal Availibility of Gopher Tortoise Forage Figure 1. Relative location of gopher tortoise study colonies. 246 Marshall and Stout centered quarter method (Cottam and Curtis 1956) , with the burrow serving as the center point of the quarters. This methodology was adopted to facilitate sampling each burrow in a radial pattern. McRae, et al. (1981) reported that tortoises often feed in a circular or elliptical pattern around the burrow. A maximum of 10 m from the center point was sampled for each quadrant. Although the feeding radii of tortoises may vary, they have been observed feeding in the vicinity of their burrows (McRae, et al. 1981, Wright 1982). Ten meters was chosen as the sampling radius because it was believed it would include most principal forage types. Eight randomly-selected sampling plots were located along randomly- selected, intersecting compass lines, with two plots per quarter (Figure 2). Each plot was a 0.25 m2, square quadrate that was sampled with the 100 percent clipping method (Campbell and Cassidy 1951) . At the ESC four plots per. burrow were clipped in the early spring and the remaining four were clipped in late summer. The same clipping procedure was conducted at the TP site, except at B-9 and B-14 in the late spring-early summer. Due to logistic problems, only two of the four plots per burrow were clipped. Four of the remaining six plots at these burrows were clipped in the late summer. Plots 6 and 7 at B-9 and plots 5 and 7 at B-14 were not clipped during this study. As a result, 12 plots were clipped during late spring- early summer and 16 were clipped during late summer at this site. Figure 2. Diagram of vegetation sampling scheme.

Plants were identified using Radford, et al. (1968). All herbaceous plants not classified as grasses or legumes were classified as forbs. Sedges (Cyperaceae) were grouped with the grasses, and all tree seedlings less than 0.50 m were grouped with the shrubs. No shrub or tree greater than 0.50 m was clipped. Each category was ranked according to its estimated relative abun¬ dance, with a value ranging from 1 to 4. The most abundant category in a plot was given the rank of 1 and the least abundant category was given the rank of 4. When more than one category was absent, each was ranked 4(0). Canopy cover analysis used the point— centered quarter method (Cottam and Curtis 1956), with the burrow serving as the center of the 4 quarters. Canopy cover was analyzed around 3 burrows at the ESC (B-l, B-6 , B-ll) and four burrows at the TP site (B-5, B-7 , B-12, B-21) . The distance from the center point, diameter at breast height (dbh) , and species of each tree were recorded. The mean basal area, absolute density, and absolute dominance were calculated using the methodology of Mueller-Dombois and Ellenberg (1974) . RESULTS Nineteen burrows were located at the ESC in an area of approximately 1.2 ha (Density — 15.8 burrows/ha) , of which 10 (52.6%) were considered active. Forty burrows were found at the TP site occupying an area of approximately 1.2 ha (Density - 33.3 burrows/ha), 24 (60%) of which were considered active. Table 1 shows the number of plots in which each vegetation category was represented at the ESC. The number of plots in which each vegetation category was present at the TP site is shown in Table 2. Ten (83.3%) of the early spring plots at the ESC were dominated by grasses. Forbs composed the principal ground cover in the remaining two (16.7%) early spring plots. Grasses were also the most abundant category in 11 (91.7%) of the late summer plots at the ESC. The one remaining late summer plot at this site was dominated by shrubs. Legumes did not domi¬ nate in any of the sample plots at the ESC in either season, and only four species of legumes were identified from this site: butterfly pea ( Centrosema virginianum ) , littleleaf sensitive brier ( Schrankia micro- phylla) , pencilflower ( Stylosanthes biflora ) , and Florida goats rue ( Tephrosia florida) . The only legume species found in the one early spring plot at the ESC was littleleaf sensitive brier. The other three legume species were present in the late summer plots. The mean basal area at the ESC was 60.7 cm2(SD - 176.40), with an absolute density of 27.7 trees/100 m2. Longleaf pine was the dominant tree species . Grasses were the dominant ground cover in 9 (75%) of the late spring-early summer plots at the TP site. Two (16.7%) of the late spring- 249 Seasonal Availibility of Gopher Tortoise Forage early summer plots at this site were dominated by forbs , while shrubs were the most abundant category in the one remaining plot during this season. Ten (62.5%) of the late summer plots at the TP site were dominated by grasses. Shrubs were the most abundant category in four (25%) of the late summer plots, and legumes were the most abundant category in the remaining two (12.5%) late summer plots. Nine species of legumes were found at this site: hog peanut ( Amphicarpa bracteata) , partridge pea senna ( Cassia fa- siculata) , sensitive senna ( Cassia nictitans) , tickclover ( Desmodium sp . ) , lespedeza ( Lespedeza sp.), roundleaf rhynchosia ( Rhynchosia reniformis) , butterfly pea, pencilf lower , and Florida goats rue. At the ESC, the mean number of plots containing legumes for both seasons was 4.5 (SD — 4.95). The mean number of plots containing legumes at the TP site was 12.5 (SD - 3.53). There was a significant difference in occurrence of legumes between the two study sites (t - 5.24, a - 0.05, df - 32) . The mean basal area at the TP site was about seven times greater than at the ESC, with 426.3 cm2 (SD — 425.75). Absolute density, however, was considerably less than at the ESC, with 3.8 trees/100 m2. Longleaf pine was also the dominant tree species at the TP site. DISCUSSION The composition of the plant communities at the two study sites was influenced by several factors. Soil associated with tortoise burrows at both sites are characterized by Hickman and Owens (1982) as droughty and low in fertility. Greater drainage and increased leaching of nutrients would have occurred at the ESC, however, because of the steeper slopes. This may have accounted for some of the differences in the vegetation between the two study areas . Garner and Landers (1981) observed that herbaceous vegetation pro¬ duction on their study areas in southwestern Georgia was lower on steep slopes than in shallow loamy sands. But they noted that the actual composition of groundstory vegetation was a function of successional stage. One of the most important factors affecting succession in tortoise habitats is fire (Auffenberg and Franz 1982, Lohoefener and Lohmeier 1981). The long-term absence of fire from the ESC appears to have been a major factor affecting the deterioration condition of tortoise habitat there. The dense stands of young trees and encroachment by shrubs ap¬ parently resulted from the lack of fire, and was undoubtedly detrimental to the production of herbaceous vegetation. While grasses were abundant at the ESC, much of the grass cover, both in sample plots and in observa¬ tions of the surrounding vegetation, consisted of bluestems ( Andropogon spp . ) , which are indicative of later successional stages in longleaf pine communities (Garner and Landers 1981, Whalenberg 1946). Lohoefener and Lohmeier (1981) stated that bluestems may be difficult for tortoises to graze upon because of their dense, erect growth habit. Thus, they may not be an important forage species. Panic grasses ( Panicum spp.) and side- 250 Marshall and Stout seed grasses ( Paspalum spp.) are considered important forage species (Garner and Landers 1981) . Seeds of these two genera were found commonly in tortoise scats (Marshall, unpublished data). These grasses did not appear as abundant in the sample plots or in the surrounding habitat as the blue-stems, and they probably decreased in occurrence as succession proceeded. Garner and Landers (1981) noted that panic grasses in their study areas in southwestern Georgia declined through subsequent succes- sional stages. Notably absent in samples and scats from both study areas was wiregrass ( Aristida spp.). Wiregrass has been reported as a major component of gopher tortoise diets throughout their range (MacDonald and Mushinsky 1988, McRae, et al. 1981, Mount 1975, Wright 1982). It is also considered an indicator of soils that have not been mechanically disturbed (Means 1988). The absence or scarcity of wiregrass from these sites may have resulted from past land use practices, such as disking or site preparation. These practices may also have affected the composition of the existing vegetation, by favoring species more tolerant of soil distur¬ bance. Auffenberg and Franz (1982) noted that bluestems invade some areas where wiregrass has been removed. In addition to natural successional events, the absence of fire from the ESC would also account for the relative scarcity of legumes from this site. The frequency of legume occurrence in coastal plain habitats has been directly related to both the frequency and recency of fire (Lewis and Harshburger 1986). Garner and Landers (1981) reported that legumes were the most important forb in the diet of gopher tortoises in southwestern Georgia. They proposed that the depletion of this preferred food may con¬ tribute to the dispersion of juveniles from the center of adult activity. Legumes were apparently important in the diets of ESC tortoises as well. In spite of the scarcity of legumes in the sample plots, the leaves and stems of Florida goats rue were seen frequently in tortoise scats (Marshall unpublished data). Tortoises apparently selected for legumes, panic grasses, and side-seed grasses over more common though less pre¬ ferred forage types. Conditions at the TP site differed sharply from those at the ESC. Timber harvesting and prescribed buring at the TP site resulted in a much larger mean basal area and a lower absolute density than at the ESC. This combination of management practices produced a relatively open canopy and encouraged the growth of herbaceous vegetation. The presence of fire was especially beneficial for controlling shrub invasion and recycling nutri¬ ents (Garner and Landers 1981, Komarek 1974). Open canopy habitat has also been correlated with high tortoise densities (Auffenberg and Franz 1982, Landers and Speake 1980). Dense tree growth and the resulting canopy closure reduce light intensity at ground level. High light levels are considered important not only for the production of forage, but to provide sufficient radiat energy for incu¬ bation of the tortoise's eggs (Auffenberg and Franz 1982, Landers and Speake 1980) . 251 Seasonal Availibility of Gopher Tortoise Forage The high percentage of late summer plots (25%) dominated by shrubs was attributable to the sample plots at B— 9 and B— 14. These burrows were located at the edge of the main colony in an area that had escaped recent burning. As a result, shrubs were more prevalent around these burrows than elsewhere at this site. The abundance of shrubs around these burrows also accounts for the TP site containing a higher percentage of plots with shrubs than the ESC (Tables 1 and 2) . The higher percentage of legumes in the late summer samples compared to the late spring-early summer samples contrasted with the observations of McRae, et al. (1981). They reported that legumes were absent in later summer samples in southwestern Georgia, and believed that the absence of legumes was due to depletion by tortoise grazing. Tortoises in the TP colony may have selected more heavily for grasses, resulting in less grazing pressure on legumes. Periodic examination of tortoise scats, however, revealed the leaves and stems of Florida goats rue to be common food items (Marshall, unpublished data). A more likely explanation might be that legumes were so abundant that grazing pressure by tortoises was insufficient to deplete them. Grasses of the genera Panicum and Paspalum were encountered more frequently at the TP site than at the ESC. This may have been attributable to the more frequent and recent fires at the TP site, which would have encouraged the growth of these grasses. Soil dis¬ turbances associated with timber harvesting may have also favored these grasses! Garner and Landers (1981) found that panic grasses were the most common species in areas subjected to timber site preparation. Although several factors influenced tortoise population structure at these study areas (Marshall 1987) , the availability of preferred forage was believed to be a major one. The absence of fire from the ESC resulted in the deterioration of suitable habitat and reduced both the quality and quantity of preferred forage. Habitat availability at the TP site was much more restricted than at the ESC, but frequent fires and low tree density increased the carrying capacity of this site. Fire was especially important to the production of legumes , and may have produced them in such abundance as to reduce the effects of grazing pressure by tortoises. MacDonald and Mushinsky (1988) concluded that the gopher tortoise is an opportunist, which chooses its foods based on the locality in which it lives. It is reasonable to assume, however, that tortoises may select certain forage types that may not be readily available, based on specific nutritional requirements (i.e., legumes) or foraging ability (Paspalum vs Andropogon) . Animals in this study, especially at the ESC, apparently have exhibited such feeding behavior. Individual tortoise populations, such as the TP colony, also appear to respond favorably to those con¬ ditions which increase both the quantity and quality of herbaceous forage.

Lee Stribling Department of Zoology and Wildlife Science and Alabama Agricultural Experiment Station Auburn University , AL 368A9 and Dan W. Speake U. S. Fish and Wildlife Service Alabama Cooperative Fish and Wildlife Research Unit Auburn University , AL 3684-9 ABSTRACT Tree climbing ability of eastern cottontails ( Sylvilagus floridanus ) has not been previously reported. However, we observed a radio— collared eastern cottontail outside of its usual home rage using an erect, hollow red maple (Acer rubrum ) as diurnal cover. We suspect a predator may be responsible for forcing the cottontail out of its original home range and provoking the tree climbing behavior. NOTE Cottontail rabbits are known to use ground holes and logs as escape and protective cover (Haugen 1943, Lewis 1972, Trent and Rongstad 1974, Anderson and Pelton 1976, Chapman et al. 1982) and use cursorial loco¬ motion as the primary means of escape (Verts et al. 1984). However, this note reports the utilization of an erect, hollow tree as diurnal cover by a male cottontail rabbit. The cottontail was trapped on 24 January 1988 as part of a movement and habitat study on the Piedmont Agricultural Substation in Camp Hill, Alabama. Upon capture, the cottontail was sexed, weighed, and fitted with a radio transmitter. The rabbit remained within an area of 7.5 ha until 5 March 1988, when the radio signal was located outside of the rabbit's usual home range. The radio signal was located in a hollow red maple 0.5 km from a location recorded the previous evening. The antenna was removed from the radio receiver to determine the precise location of the radio in the tree. After thoroughly searching the tree for the peak radio signal, we determined the radio was 3.7 m above Manuscript received 17 March 1990; accepted 16 May 1990. 2Cooperators : U. S.

We assumed the rabbit was dead and the radio was left in the tree by an avian predator. Therefore, the radio was not monitored again until the tree was cut on 10 March to retrieve the radio. The tree was 17 m tall, with the hollow cavity extending from ground level to 7 m high. The basal diameter of the cavity was 15.2 cm, but it tapered to 11.4 cm at 4.6 m high. An opening at the base of the tree provided access to the cavity. After an examination of the tree yielded no radio, we began to search for the signal. The rabbit was found alive and within its original home range, where it remained until 27 March 1988 when it successfully slipped, the attachment collar and removed the radio transmitter. Arboreal behavior among members of Sylvilagus has been reported. Mountain cottontails ( Sylvilagus nuttalli) have been observed to climb small junipers ( Juniperus occLdentalis ) in order to obtain water droplets which exude from the leaf surface at night. This apparently adaptive behavior has allowed S. nuttalli to successfully occupy habitats at the periphery of its range (Verts et al. 1984). Swamp rabbits (S. aquaticus ) occasionally use hollow trees as escape cover from hunting dogs (Lowe 1958) . We suspect a predator may be re¬ sponsible for forcing the cottontail we monitored out of its normal area and for causing the climbing behavior demonstrated by this animal, al¬ though this is only speculative. Nevertheless, climbing trees as a mode of escape or use of erect trees as diurnal cover by eastern cottontails has not been noted previously in the literature.

PHYSIOLOGICAL RESPONSE TO JUMPING ON THE LOLOBAL AT THREE DIFFERENT FREQUENCIES1 Tamara Kumler and Kennon Francis Division of Physical Therapy • University of Alabama, at Birmingham Birmingham, A L 3 529 A ABSTRACT Heart rate and V02 (mlkgmin-1) of 10 men and 9 women were measured while jumping for five minutes at frequencies of 104, 126, and 144 jumps/ min(JPM) using a new jumping device called a "Lolobal" . Mean V02 ( + SD) for respective jumping rates were 25.7+3.9, 24.6+3.7, and 24.8 + 4.5 ml -kg min-1 respectively. Corresponding mean heart rates (+ SD) at the jumping frequencies of 104, 126 and 144 were 152,3 + 23.1, 147.2 + 22.5, and 151.7 + 18.4 beats/min. The intensity of exercise with the Lolobal resulted in V02 values that ranged from 50% to 60% of the subjects' V02 max level and heart rate values that ranged from 70% to 77% of maximum. These values border on the lower end of the American College of Sports Medicine's suggested range of intensity levels that are necessary for producing a training effect. It can be concluded that the work intensity of jumping with this new device might be a suitable alternative for low to moderate intensity exercise regimens requiring an intensity of approxi¬ mately 24.5 mlkgmin-1 of oxygen consumption. However, in order to determine the training effectiveness of this new device, longitudinal studies are required. INTRODUCTION Individuals desiring to maintain or initiate an exercise program are continually searching for convenient activities that provide vigorous physical exercise, yet are inexpensive and can be performed under time limiting schedules. Activities such as running, swimming, and bicycling are among the more traditional favorites. Recently, jumping exercises such as rope skipping and rebounding exercise using a minitrampoline have become popular because they are economical and easily accessible. These types of jumping activities require little space to perform and individu¬ als can exercise in the privacy of their home, apartment, or motel room. Studies of physiological responses and training effects indicate that both rope skipping and rebounding can be used to improve cardiovascular en¬ durance, however the general application of these devices to all indi¬ viduals is not without limitations (Ballard, Dal Pozzo, and Healey, 1984; Bishop, Smith, Everett, 1986; Bruce, 1971; Bruce, 1974; Solis, Foster and Thompson, 1988; Town, Sol, and Sinning, 1980). Several studies suggest that rope skipping may be too strenuous for the average individual (Bruce, 1971; Getchell and Cleary, 1980; Jette , ^Manuscript received 5 December 1989; accepted 10 April 1990. 258 Kumler and Francis Mongeon, and Routhier, 1979) and rebounding may not produce a sufficient Intensity of exercise for a well trained individual (Ballard et al. , 1984; Bishop, Smith, and Everett, 1986). The Lolobal (In-Tech Marketing, Doylestown, PA) (Figure 1) is a new jumping device that incorporates attractive aspects of both the jump rope and rebounding. The Lolobal incorporates the Jump rope features of convenience, economy, and the requirement for little space, and the rebounding feature of a cushioning effect during the jumping activity. Figure 1. Positioning of the subject used in this study to measure effects of jumping on the Lolobal. Lolobal is manufactured by In-Tech Marketing, Doylestown, PA. 259 Physiological Response to Jumping on the Lolobal Because of the relative newness of this exercise device there have been no standardized measurements of the energy consumption relative to its use. Therefore the purpose of this study was to quantify selected physiological responses while using this new device in order to determine its usefulness for aerobic training. The oxygen consumption and heart rate response of 10 men and 9 women were measured while jumping at three frequencies (104, 126, 144 jumps/minute ( JPM) ) . METHODS Sub jects Nineteen healthy subjects, ten males and nine females, mean age 24 years were selected from a group of volunteers of University of Alabama at Birmingham (UAB) students. A summary of their physical characteristics is shown in Table 1. Subjects used in the study were non-smokers with no history of orthopedic or cardiovascular abnormality and no reported sur¬ gery or hospitalization in the past year. All subjects were active, healthy individuals as indicated by the average maximal V02 values of 45 ml kgmin-1. None of the subjects were competitive or trained athletes. Standard informed consent procedures were used and the protocol was approved by the Institutional Review Board for Human Use at the University of Alabama at Birmingham. Table 1. Characteristics of Subjects. Age Weight Height V02max Heart rate maximum (yr) (kg) (cm) ml kg min beats/min 24.1 ± 2.1 67.5 ± 10.0 174.5 ± 7.3 45.1 ± 8.2 191.6 + 8.4 Values represent the mean + standard deviation. Apparatus The Lolobal is a round rubber ball approximately the size and pos¬ sessing the resiliency of a volleyball (Figure 1) . The ball has a round 18 inch diameter platform attached midcircumference for placement of the feet while jumping. Oxygen consumption was determined using a standard open-circuit, semi-automated protocol. Values of oxygen consumption during the treadmill test were measured using expired gases collected in a Tissot spirometer; alliquots of expired gases were analyzed for oxygen using a Beckman 0M11 analyzer and carbon dioxide using a Beckman LB2 analyzer. Both analyzers were calibrated with standardized gas before each test. Heart rates were monitored using a CM5 electrocardiograph. A Quinton Model 24-72 treadmill was used for the maximal physical work capacity test. The Lolobal was maintained at a pressure of 10 psi as 260 Kumler and Francis recommended by the manufacturer. A mechanical metronome was used to maintain the specified jumping rates. No stabilization device is included with the Lolobal for maintaining balance while jumping. Because the subjects were unskilled and novices at jumping with the Lolobal, a handrail was used to standardize stability and eliminate possible variability due to dexterity. Subjects maintained their balance while jumping by placing their open palsm on a horizontal bar, which was adjusted to the height of their anterior superior iliac spine. Subjects were instructed not to grip the bar, but simply to touch the bar for stability. Procedures Prior to initiating the study it was determined that the minimal and maximal jumping frequencies that could be sustained for five minutes with the Lolobal were 104 and 144 jumps/min (JPM) respectively. The elasticity of the Lolobal would not support jumping rates lower than 104 JPM. Jump¬ ing rates higher than 144 JPM resulted in failure of the Lolobal to adequately clear the ground while jumping. The study consisted of four individual exercise sessions fot each participant separated by a time period of at least 24 hours. During the first session, maximal oxygen consumption and maximum heart rate were determined by a progressive Bruce treadmill test (Bruce, 1971; Bruce, 1974) to volitional exhaustion. In the subsequent sessions, subjects jumped on the Lolobal for five minutes using one of three randomly as¬ signed jumping rates of 104, 126, or 144 JPM. Five minutes of exercise was chosen in order to insure a steady rate of the exercise heart rate and V02. Heart rate and V02 were recorded during the last twenty seconds of every minute. The means of minute four and five were used in statistical analysis. On the day prior to the first jumping session, subjects were allowed to experience jumping at the different frequencies and familiarize themselves with the various testing equipment. Student's t test was used to determine differences between gender at each of the jumping frequen¬ cies. Because there was no statistical difference between gender, com¬ bined values were used for conducting a repeated measures ANOVA to test for significant differences in heart rate or V02 due to jumping rate. A P value of <0.05 was established as the minimal criterion for signifi¬ cance . RESULTS The means + SD of V02, work intensity, and heart rate, at each of the three jumping frequencies are shown in Figure 2. Mean values of V02 at the respective jumping rates of 104, 126, and 144 JPM were 25.7 + 3.8, 24.6 + 3.7, and 24.8 + 4.5 ml kg min respectively, which represented 50 to 60% of the subjects' V02max. There was no statistical difference between any of the values. Mean heart rates were 152.3 ± 23.1, 147.2 + 22.5, and 151.7 + 18.4 beats/min which represented 70% to 77% of the subjects' maximum heart rate. There was no statistically significant difference between any of the values. 261 Physiological Response to Jumping on the Lolobal DISCUSSION The relative newness of this form of exercise and the absence of comparative studies with standardized measurement and protocols makes this study of jumping on the Lolobal somewhat unique. The narrow range of 24 6 — ^’7 to 25.7 ± 3.8 ml kg min in V02 and heart rate response (147.2 + 22.5 to 152 + 23.1) shown in Figure 2 was not altogether surprising. A similar type of response has been reported for jumping with a jump rope. Quirk and Sinning (1982) and Town, Sol, and Sinning (1980) have reported that the V02 requirement and heart rate response for jumping rope does not Increase with skipping rate over a relatively wide range (i.e., 120 to > JUMP8/MINUTB Figure 2. Oxygen consumption and heart rate response of nineteen subjects while jumping on the Lolobal at three jumping frequencies of 104, 126 and 144 jumps per minute. 140 JPM) . Only extremely high rates of 160 JPM and above required sig¬ nificantly more oxygen and resulted in significantly different heart rates. Quirk et al. (1982) suggested that there is a threshold rate between 140 and 160 JPM where V02 increases unproportionally to jumping frequency, leading to a higher oxygen requirement and heart rate response. The highest jumping frequency used in this study of the Lolobal did not cross this threshold, which might explain the similarity of the V02 recorded for the various jumping frequencies. Another explanation for the similarities in oxygen consumption while jumping at the different frequencies on the Lolobal might be due to the mechanics of jumping. Town, et al. (1980) found from cinematographic 262 Kumler and Francis analysis that during jumping rope, a decrease in average vertical dis¬ placement takes place with an increase in jumping rate. This same phenomena was visually observed during jumping on the Lolobal. The jump height perceptively decreased with increasing jumping frequency which may have accounted for the similarity in oxygen consumption values despite the increase in jumping rate shown in Figure 2. The intensity of exercise with the Lolobal resulted in V02 values that ranged from 50% to 60% of subjects' V02max level. These values border on the lower end of the American College of Sports Medicine's suggested range of intensity levels that are necessary for producing a training effect in training activities. It can be concluded that the work intensity of jumping with this new device might be a suitable alternative for low to moderate intensity exercise regimens requiring an intensity of approximately 24.5 ml kg min of oxygen consumption. However, in order to determine the training effectiveness of this new device, longitudinal studies are required. REFERENCES American College of Sport Medicine .

COMMODITY FLOW AND REGIONAL ECONOMIC DEVELOPMENT ALONG ALABAMA'S TENNESSEE RIVER1 Jeffrey P. Richetto Department of Geography University of Alabama Tuscaloosa, AL 35^87 INTRODUCTION In 1933, the Tennessee Valley Authority, TVA, was established and given a mandate from Congress to identify and develop the full resources of the Tennessee River, including but not limited to regulating and improving its flood waters, navigation, and power generation. TVA has and continues to demonstrate remarkable success in accomplishing all three objectives. By 1945, the development of the Tennessee River was nearly completed with the construction of seven dams and navigation locks. These newly built structures, along with two existing locks and dams, have allowed commercial vessels to move with equal ease upstream or downstream, changing elevation by more than 500 feet. At present, the commercially navigable waterway consists of 650 miles of main channel and nearly 150 miles of tributary and secondary channels. The Tennessee River flowing from Knoxville, Tennessee to Paducah, Kentucky, connects with the recently completed Tennessee-Tombigbee waterway system at Yellow Creek, Mississippi and is part of the United States' Interconnected Inland Waterway System (Figure 1) . The completion of the Tennessee River as a commercial waterway has created a valuable tool providing the basis for economic development throughout the Tennessee Valley region. For example, since 1945, the private sector has committed investments of nearly $5 billion in Tennessee River waterfront plants, terminals, and distribution facilities (Table 1) . Moreover, because waterway transportation has been a comparatively low- cost, energy efficient, safe mode of movement, the total amount of tonnage trafficked along the Tennessee River has increased nearly seventeenfold between 1945 and 1986 (Figure 2). In this way, major industrial growth areas have been identified and partially developed along the waterway. Approximately 42 public-use and 140 special commodity private— use termi¬ nals are currently in operation. While public-use terminals are designed primarily to serve off— river industry and business, private-use terminals are utilized for specific traffic of their owners, usually serving a waterfront establishment. Prior to the completion of the Tennessee River the regional economy of the Tennessee Valley was characteristically localized, emphasizing agriculture and extractive industry. With the exception of Chattanooga and Knoxville, Tennessee towns along the waterway were generally small, rural trade centers. Although these two metropolitan areas have benefit- manuscript received 7 July 1990; accepted 17 August 1990. 265 Richetto Figure 1. The U.S. Interconnected Inland Waterway System. ted from the improved channel, the more dramatic growth has occurred in the smaller, rural centers along the entire stretch of the river including Calvert City, Kentucky; New Johnsonville , Counce, Charleston-Calhoun, Clinton, and Loudon-Lenoir , Tennessee; and Muscle Shoals, Decatur, Court- land, Guntersville , and Scottsboro-Stevenson, Alabama (Figure 3). Several similarities exist between these port centers including the availability of commercial navigation in combination with related inland transport networks such as rail and highway, flood-free sites for industrial development, and an uninterrupted supply of process and cooling water. 266 Commodity Flow and Regional Economic Development Table 1.

Inasmuch as these centers have accounted for more than 90 percent of the total capital investment along the Tennessee River during the past two decades, they may be considered as 'growth poles' within the Tennessee Valley regional economy. In an effort to evaluate their potential for continued economic support in the growth and development of the region as a whole, it is informative to determine their interport (on-river) com¬ modity flow including its functional and geographic extent. It is within this context that this study examines the above characteristics for the port center of Decatur, Alabama. COMMODITY FLOWS AND ON-RIVER HINTERLANDS Since the early 1980s the nature and role of inland waterway ports in the United States have undergone dramatic change. On the one hand, these changes have been reflected in the development of new technologies including double-stack trains and super containerships (Fahrenwald, 1988; Chilcote, 1988). Container traffic accounts for nearly one-half of all rail intermodal volume and three -fourths of the general cargo handled at U.S. ports. Economic and technological innovations stimulated by con¬ tainerization have modified the geography of movement in the United States, effectively eliminating inland waterway commerce for the lucrative general cargo market. Despite the fact that 16 percent of all the nation's freight moves on the inland waterway system, virtually no containers move on barges (U.S. Army Corps of Engineers, 1983). To a greater degree, however, have been the changes occurring in the overall operating environment of the port. New government policies, 269 Richetto innovative management directives, and a realignment of international economic relationships have impacted significantly on a port's traditional service area as well as its marketing strategy (Dicer, 1986). The growth of strategic planning and the development of formal plans on the part of several ports are evidence of their recognition of the new operating environment and their desire to direct future changes rather than to be acted upon. Nevertheless, even with the establishment of such strategic programs many ports struggle with the twin issues of market identification for their services and marketing the facilities of the port for the pur¬ pose of supplying consumer demands through the exchange process. Historically, the inland transportation industry operated under strict government regulation. Primarily through the Interstate Commerce Commission, the federal government regulated the rates that could be charged for specific movements and the type and location of services. Under such a regulated system, transportation companies were limited in their ability to adjust quickly to changing market conditions in an effort to attract business. As a result, market areas were delimited primarily by geographic distance wherein (1) the cost of inland transportation was considered the primary factor in routing shipments and (2) the cost of inland transportation was a direct function of both distance over which movement occurred and weight of the commodity being moved. In this way, transportation centers, for example ports, functioned as monopolies serving a 'natural' tributary hinterland. Since the later 1970s, however, there has been considerable deregulation in the U.S. inland transportation industry. One of the more significant changes, especially as it impacts on the on-river market area of ports, is the ability of railroads to set spot rates and to enter into contracts with shippers. This added capability allows intermodal carriers to establish competitive rates negating the benefits of once lower line- haul costs of waterway transportation. As a result, the traditional natural tributary hinterland for a port has all but disappeared while the role of geographic distance for delimiting the spatial extent of a port's market area has lessened considerably. Dicer (1986) identifies several ways by which a port may improve its competitiveness in- such a new and dynamic operating environment: (1) delimit a port's hinterland through the identification of customers and their service needs, (2) integrate a marketing research effort into the ongoing activities of the port, (3) employ market segmentation techniques to establish profitable market niches, (4) consider the marketing program as a totally integrated effort, and (5) recognize the role of the port in the ever-changing international distribution environment. In addition, a port may play an important role in the overall eco¬ nomic development of a region. First, it must be determined whether or not a port is able to attract economic development both locally and regionally (through an established, interconnected trade network with other ports) and second, it is necessary to measure the geographic extent and degree of a port's local and regional connectivity. A port's local and regional market area may be delimited according to scale, function, 270 Commodity Flow and Regional Economic Development and specificity; that is, (1) a single terminal or group of terminals (designated by a given river mile), (2) on-river (interport) or off-river (terminal -to -end user) connections, (3) total tonnage trafficked, (4) inbound vs. outbound traffic, (5) commodity classification codes, or (6) any combination of the above. Within this context, this study measures the interport hinterland for the port city of Decatur, Alabama. Specifi¬ cally, this study examines the type and quantity of inbound/ outbound commodities and their origin and destination for the years 1970, 1975, 1980, 1984, and 1985. THE NORTH ALABAMA CORRIDOR: THE ROLE OF THE DECATUR PORT The development of the Tennessee River has resulted in a commercial¬ ly navigable waterway of which 202 miles constitutes the North Alabama Corridor, (Figure 4). Within the twelve-county corridor, a dynamic transportation network including air, highway, rail, and water offers industry strategic access to local, regional, and national markets. Moreover, 85 of the nation's 500 largest corporations have located sub¬ sidiary or divisional operations within this area. Nearly $12 billion is spent annually by the O.S. Government and Procurement Facilities in the region and the overall industrial base of the region is represented by virtually all standard industrial classifications. Among the several port centers along the Tennessee River situated within the Corridor, Decatur represents a center of sizable trade and industrial development. With its central location Decatur enjoys a comparative trade advantage over the state's other ports along the Tennessee River by serving directly several regional metropolitan areas including Nashville, Tennessee and Huntsville and Birmingham, Alabama. Moreover, its population size of nearly 60,000 and its relative location to the U.S. Interconnected Inland Waterway System enable Decatur to serve a more prominent role in the interport hinterland of the nation's inland waterway industry. Although Decatur handles a diversity of commodities, the port center's public and private terminals are characteristically 'sinks' on the Tennessee River averaging nearly 88 percent of their total traffic as inbound shipments (Figure 5) . 271 Richetto Decatur River Mile no. 45301 Year E3 Inbound ■ Outbound Decatur River Mile no. 45304 Year Figure 5. Total Torjnage of Inbound and Outbound Shipments for Select Terminals in the Port Center of Decatur. COMMODITY FLOW ANALYSIS The port center of Decatur is served by a total of 14 terminals; 4 public and 10 private. In order to ensure the conf identiality of indi¬ vidual terminal operators, commodity flow data were obtained from eight terminals and aggregated into a single data base. Table 2 indicates the total inbound/outbound tonnage of shipments for all major commodity groups. With the exception of coal and sand, Decatur has experienced a significantly larger inbound as opposed to outbound shipment of com¬ modities. This relationship is particularly evident for grains and chemicals where' the tonnage of inbound shipments Was on the average nearly ten times greater than the tonnage of corresponding outbound shipments . Since 1980, the port center of Decatur has increasingly served as a termination point for interport traffic. Between 1980-85 the total tonnage of inbound shipments increased from 350.5 thousand to over 373 thousand (6.6%) while at the same time the total tonnage of outbound shipments decreased from 85.8 thousand to 49 thousand (-43.3%). Histori¬ cally, although coal, iron/steel, and chemicals dominated the in and outbound shipments; since 1980, grains (especially corn and grain mill products), fertilizer, and building cement have become the more trafficked commodities. Between 1980 and 1985 nearly 60 percent of all inbound traffic was grain and grain mill products of which 94 percent was corn. Building cement averaged 12 percent per year while fertilizer accounted for slightly over 10 percent. Although iron/steel in the form of pipes represented a sizable share of outbound shipments (27 percent in 1985); sorghum, soybeans, and grain mill products combined to total over 35 percent and chemicals 12 percent for the same year . - 272 Commodity Flow and Regional Economic Development Table 2.

Between 1970 and 1980 Decatur's inbound shipments included a total of 16 different commodities while its outbound shipments included a total of 7 different commodities, averaging slightly over a 2:1 ratio of inbound to outbound traffic. Although the 2:1 ratio remained in force throughout the following five-year period the total number of different inbound and out¬ bound commodities handled increased significantly, 29 and 16 respectively. An even greater difference between inbound and outbound shipments is evidenced in the tonnage trafficked. For example, while the ratio of the number of inbound to outbound commodities averaged nearly 2:1 (1980-85) the corresponding tonnage of inbound to outbound shipments averaged over 7:1 during the same time period. Table 2 indicates that for all major commodity groups with the exception of coal and sand the port center of Decatur had significantly larger inbound as opposed to outbound traffic. This was especially evident for grains and chemicals where the tonnage of inbound shipments was more than ten times greater than the tonnage of outbound shipments . Finally, because of its relative location on the Tennessee River, along with a well-developed and integrated off-river transportation network, Decatur serves an important role to both the Tennessee Valley region and the U.S. inland waterway system. Of the over 180 terminals operating along the Tennessee River, the few terminals located in Decatur handle a disproportionately large share of certain commodities, especially grains. Since 1975 the percentage share of total river shipments for grains trafficked through Decatur increased from 0.1 percent to 5.5 per¬ cent in 1985 (Table 3). Other major commodity groups exhibiting smaller percentage increases included iron/steel and the category labelled others. During the same time major commodity groups experiencing a decreasing role in percent share of total river traffic included chemicals, coal/coke, and petroleum products. Moreover, Decatur handles a sizable diversity of com¬ modities including 29 different inbound and 16 outbound products. How¬ ever, in 1985, nearly 85 percent of total inbound shipments specialized in only three products; grains, 58.2 percent, fertilizer, 17.9 percent, and iron/steel, 7.2 percent. Similarly, over 70 percent of outbound traffic included only two products; iron/steel, 43.8 percent and grains, 26.6 percent. Although the port center of Decatur continues to function primarily as an on-river point of termination or sink, since 1970 this role has les¬ sened considerably. While over 600,000 tons of products were received in 1970 only 373,000 tons of inbound shipments occurred in 1985, a decrease of 39 percent. This sizable percentage change in inbound traffic was largely attributed to significant decreases in incoming shipments of coal tar, iron/steel, and lubricating oils. SUMMARY AND CONCLUSION The several port centers along the Tennessee River are character¬ istically different in terms of tonnage and diversity of commodities 274 Commodity Flow and Regional Economic Development Table 3.

Richetto trafficked and their primary function on the river which is reflected in their service capabilities, relative location, and surrounding transpor¬ tation infrastructure. The port center of Decatur, in particular, pos¬ sesses several excellent advantages which allow the port to serve pri¬ marily as a sink or termination point on the river. For example, Decatur's relative location on the Tennessee River is accessible to both Figure 6. Decatur's Interport Hinterland for Inbound Shipments, 1975, 1980, and 1985. 276 Commodity Flow and Regional Economic Development the U.S. inland waterway system and the several major port cities along the eastern segment of the Tennessee River (Figure 6). Moreover, Decatur is served by a well established multimodal, off- river transportation network linking it to the Southeast's regional economy and, in particular, Alabama's local economy (Figure 7). Finally, Decatur is one of the larger ports on the Tennessee River and is situated within a growing and econom¬ ically developing region within the state. Figure 7. Decatur’s Interport Hinterland for Outbound Shipments, 1975, 1980, and 1985. 277 Richetto In an effort to more fully understand the potential role of ports along the Tennessee River in the Tennessee Valley's regional economy, additional commodity flow studies for other ports are needed. The trends and spatial organization of interport and off- river hinterlands must be identified. Such a data base could prove to be invaluable for terminal operators seeking to either more fully develop their existing markets and/or to expand into other geographic or product markets.

Membership application forms can be obtained from Dr. Ann William, 101 Cary Hall, Auburn University, AL 36849. Subject matter should address original research in one of the discipline sections of the Academy: Biological Sciences; Chemistry; Geology; Forestry, Geography, Conservation, and Planning; Physics and Mathematics; Industry and Economics; Science Education; Social Sciences; Health Sciences; Engineering and Computer Science; and Anthropology. Timely review articles of exceptional quality and general readership interest will also be considered. Invited articles dealing with Science Activities in Alabama are occasionally published. Book reviews of Alabama authors are also solicited. Submission: Each manuscript will receive at least two simultaneous peer reviews. Include in your letter of transmittal the names, addresses, and telephone numbers of at least four qualified referees. Do not include names of individuals from your present institution. Manuscripts : Consult recent issues of the Journal for format. Double¬ Space manuscripts throughout, allowing 1— inch margins. Number all pages. Submit the original and two copies to the Editor. Papers which are unreasonably long and verbose, such as uncut theses, will be returned. The title page should contain the author's name, affiliation, and address, including zip code. An abstract not exceeding 200 words will be published if the author so desires. Use headings and subdivisions where necessary for clarity. Common headings are: INTRODUCTION (including a literature review), PROCEDURES (or MATERIALS AND METHODS), RESULTS, DISCUSSION, and LITERATURE CITED. Other formats may be more appropriate for certain subject matter areas. Headings should be in all— caps and centered on the typed page; sub— headings should be italicized (underlined) and placed at the margin. Avoid excessive use of footnotes. Do not use the number 1 for footnotes; begin with 2. Skip additional footnote numbers if one or more authors must have their present address footnoted. Illustrations : Submit original inked drawings (graphs and diagrams) or clear black and white glossy photographs. Width must not exceed 15 cm and height must not exceed 20 cm. Illustrations not conforming to these dimensions will be returned to the author. Use lettering that will still be legible after a 30% reduction. Designate all illustrations as figures, number consecutively, and cite all figures in the text. Type figure captions on a separate sheet of paper. Send two extra sets of illustra¬ tions; xeroxed photographs are satisfactory for review purposes. Tables: Place each table on a separate sheet. Place a table title directly above each table. Number tables consecutively. Use symbols or letters, not numerals, for table footnotes. Cite all tables in the text. Literature Cited: Only references cited in the text should be listed under LITERATURE CITED. Do not group references according to source (books, periodicals, newspapers, etc.). List in alphabetical order of senior author names . Cite references in the text by number or by author- date .
