CARROLL* and M. PETE THOMPSON, Department of Biological Sciences, Eastern Kentucky University, Richmond, KY 40475 *Present address: Department of Biology, University of North Dakota, Grand Forks, ND 58202 ABSTRACT The survival, dispersal, and home range of wild turkeys (Meleagris gallopavo sylvestris) released into unoc- cupied habitat in eastern Kentucky was investigated. Twenty four turkeys were captured in Virginia and western Kentucky, transported to the study area, and released. Ten of these birds were outfitted with radio transmitters prior to release. Fifty per cent of the radio-tagged turkeys died during the first month after release, with 80% of the losses attributed to great horned owl (Bubo virginianus) and gray fox (Urocyon cinereoargenteus) predation. No mortality occurred after one month but all birds were ultimately lost due to radio or harness failure. Average maximum movements from the release site during the first 12 weeks post-release ranged from 0.95 -1.75 km. Maximum dispersal was 8.0 km and occurred 6 weeks after release by a juvenile male. The average fall home range size was 197 ha for 2 males and 223 ha for 4 females. Winter and spring home ranges for 3 males av- eraged 413 ha and 239 ha, respectively. The summer home-range size for a single adult male was 47 ha. The mean three-season home range size for 3 males was 476 ha. Reproduction during the first breeding season after release indicated 3 broods of young turkeys were produced. The evidence suggests the presence of about a one- month adjustment post-release after which released turkeys appear to function as a resident population. It is ap- parent that the release of wild-trapped turkeys in eastern Kentucky, as undertaken in this study, results in at jeast short term establishment of a reproducing population. INTRODUCTION The eastern wild turkey (Meleagris gallo- pavo sylvestris) has been intensively managed thoughout the eastern United States. Much of this management has involved the restoration of wild turkeys to areas from which they were extirpated. In Kentucky, restoration efforts began in the 1940’s and continue through the present. How- ever, few efforts have been made to document the initial activities of turkeys in new habitat, and fac- tors which may influence the relative success or failure of such transplants. In other parts of the southeast several investigations have been con- ducted. Prestwich (1) studied the survival of wild turkey in central Tennessee. Eichholz and Mar- chinton (2) reported on the dispersal of 16 wild turkeys in northern Georgia. Bowman, Hill and Burleson (3) studied dispersal of turkeys in North Carolina, and Everett, Speake and Maddox (4) in- vestigated ranges of transplanted turkeys, stocked into occupied habitat in Alabama. The objectives of this study were to docu- ment the survival, dispersal and home range of wild turkeys released into unoccupied Kentucky habitat. STUDY AREA The study was conducted on the Mill Creek Wildlife Management Area of the Daniel Boone National Forest in Jackson County, Kentucky. The area is managed by the Kentucky Department of Fish and Wildlife Resources. Elevations range from 385 m to 575 m and the terrain is highly dissected with narrow v-shaped valleys ascending 2 Trans. Kentucky Academy of Science — 46(1-2) to relatively flat hilltops. The study area is heavily forested in hardwoods (63%) including white oak (Quercus alba), chestnut oak (Q. prinus), scarlet oak (Q. coccinea), northern red oak (Q. rubra), yellow poplar (Liriodendron tulipifera) and hickory (Carya spp.). Some stands of softwoods (8%) consisting of shortleaf pine (Pinus echinata) and pitch pine (P. rigida) are also present. About 17% of the area is in mixed hardwood-pine stands and the remaining 12% consists of clearcut stands which are being regenerated in shortleaf pine. The study area has been described in more detail by Carroll (5). METHODS Twenty wild turkeys were captured by rocket-net in Bath County, Virginia of which 8 were outfitted with radio-transmitters. An addi- tional 4 birds were captured in Christian County, Kentucky with oral tranquilizers and 2 of these birds were radio-tagged. Captured birds were immediately transported to the study area in cardboard boxes for release on the same day as capture. Each bird was aged and sexed (6) and weighed. A numbered aluminum wing tag was also attached to each bird. Telemetry data were collected with Model TRX-24 receivers (Wildlife Materials Inc., Carbondale, IL 62901) and a hand-held 3-element Yagi antenna. Each transmitter was on an individual frequency in the 150-151 mhz range and contained motion and mortality switches similar to those described by Bowman, Hill and Burleson (3) and Everett et al. (7). Transmitter weight ranged from 63 g to 100 g (1.2% to 2.4% of bird weight). Each radio was mounted on the bird’s back with nylon braid- coated latex tubing. The tubing was knotted under each wing and securely fastened with metal bands (3,8). Locations were determined by using triangulation from known stations and in most cases 2 bearings with an intersecting angle be- tween 60° and 120° were used to minimize error (9, 10, 11). Telemetry error of + 6.15° was calculated for the study area and equipment, and bearings were accurate within 100 m for about 90% of the locations (5). Each bird was located 2 to 5 times per day during 2 or 3 days each week from release to death or loss of signal. All locations were plotted on a USGS topographic map from which dispersal and home ranges were calculated. The minimum polygon method (12) was used to calculate home ranges. RESULTS AND DISCUSSION Known survival of radio-tagged turkeys rang- ed from 2 to greater than 223 days, as all transmit- ters eventually failed (Fig.1). Fifty % of the radio- tagged birds died within one month of release with mean survival of 14.2 days (s.d. = 11.2). After the first month post-release no deaths were known to have occurred. Four of the 5 known mortalities were the result of predation by great horned owls (Bubo virginianus) and gray foxes (Urocyon cinereoargenteus). The fifth dead turkey showed no outward signs of the cause of death and a subsequent necropsy yielded no information. The initial high rate of mortality among the released birds seems to indicate some kind of relationship with the capture-release process. It could not be determined if the resulting deaths were caused by injuries sustained during handling or from the in- experience of the birds in a new environment, making them vulnerable to predation. Results of other researchers are variable. Prestwich (1) reported 77% mortality within one month of release. He concluded that the proximity of the study area to a suburban development and free ranging dogs caused excess stress and mortality. The results of Bowman, Hill and Burleson (3) in- dicated less than 10% mortality in the first 2 mon- ths after release. Eichholz and Marchinton (2) reported similar low mortality rates. Little and Varland (13) reported mortalities of less than 40% during the first year after release. Fig 1. Survival of 10 wild turkeys released in the Mill Creek WMA during 1981-1982. J is juvenile and A is adult. Vertical bar is death of turkey and open circle is loss of signal or transmitter. Mean maximum movements away from the release sites ranged from 0.95 - 1.75 km during the first 12 weeks post-release. The longest distance moved was 8.0 km by a juvenile male. The maximum distances moved away from the release sites by individuals occurred during Wild turkeys in Kentucky — Carroll and Thompson 3 various times in the first 12 weeks. Ultimately, all but one of the surviving turkeys included the release sites as part of their home range. The gradual movements away from release sites reported by Eichholz and Marchinton (2) were not observed during this study, but, the max- imum distances moved during the first month Table 1.

Bowman, Hill and Burleson (3) found average maximum movements to be 7.0 km and concluded disper- sal continued through the first 6 months follow- ing release. The lack of dispersal found in this study may reflect the presence of a large mast crop of oaks and dogwood (Cornus florida) dur- ing the study. Post-release home range size of the radio- tagged birds surviving more than 2 weeks varied from 157 ha to 653 ha (Table 1). Fall range estimates of 197 ha for males and 223 ha for females were somewhat smaller than those reported by other researchers, but were similar to the findings reported by Raybourne (14) in Virginia. This may be due to the abundant mast crop available during the fall or some behavior changes as a result of the translocation process. The winter ranges for males averaged 413 ha which was larger than the 270 ha estimate cited by Everett, Speake and Maddox (4). The evidence suggests that birds were not restricted by deep snow and cold weather conditions as has been reported in northern regions (15). In- stead, it appeared that the birds had to increase their home ranges as the fallen mast was con- sumed. During the late fall - early winter transi- tion period, a juvenile male shifted its range about 8 km which was the only major shift in home range noted during the study. The spring gobbler home range sizes (239 ha) were similar to those obtained by Barwick Fig 2.

Kentucky Academy of Science — 46(1-2) The summer range for one adult gobbler was 47 ha which is smaller than summer ranges reported by other investigators. For example, Barwick and Speake (16) obtained a mean range for gobblers in Alabama of 133 ha, and Bowman, Hill and Burleson (3) reported sum- mer ranges of 542 ha for gobblers in North Carolina. Ranges for males based on three seasons, with an average size of 476 ha, were within the 224 ha to 1439 ha range given for the eastern wild turkey (4). This probably reflects the in- termediate climatic and habitat conditions found in the study area, as well as the condition of mast crop and distribution of mast producing stands throughout the area. These observations support the contentions of Everett, Speake, and Maddox (4) that restocked birds quickly adjust to a new habitat and assume home ranges similar to those of resident birds. The results also indicate a great spatial overlap of ranges in this study (Figs. 2-4), but as noted by Eichholz and Marchinton (2), there were temporal dif- ferences in the use of overlapping portions of the home ranges. Incidental observations of wild turkeys with- out radios were sparse. Most observations were in the vicinity of the release sites. During the first reproductive season following the release, 4 groups of hens and poults were sighted in the study area and probably represented production of 3 broods. Several gobble counts were con- ducted during April, 1982, and a maximum of 3 males were heard. All gobbling activity was restricted to the immediate vicinity of the release sites. SUMMARY The results of this study indicate that the methods utilized to transplant wild turkeys into unoccupied habitat in eastern Kentucky may be successful. It is apparent there is a short (about one month) period during which many of the released birds succumb to predation. This is probably due to some combination of capture stress and inexperience in new habitat. The lack of dispersal from release sites and rapid establishment of home ranges similar to those reported for resident turkeys suggests the lack of any long-term effects of the transplant process. Although, the presence of sufficient habitat to support turkeys in the vicinity may be the important factor in how quickly transplanted birds assume roles as a “resident” population. The subsequent production of 3 broods dur- ing the first reproductive season indicates the presence of sufficient habitat components to support turkeys through all four seasons. However, ultimate success of a transplant pro- gram can only be measured by the long-term survival of a population in addition to the short- term survival of the released birds.

Freshwater snails in Kentucky—Blair and Sickel A SURVEY OF FRESHWATER GASTROPODS IN SELECTED HABITATS OF LAND BETWEEN THE LAKES, KENTUCKY AND TENNESSEE LUCIANNE BLAIR and JAMES B. SICKEL Department of Biological Sciences and Hancock Biological Station Murray State University, Murray Kentucky 42071 ABSTRACT A survey of freshwater gastropods and an investigation of their ecological relationships were conducted at 44 collection sites in the Tennessee Valley Authority’s Land Between the Lakes in western Kentucky and Ten- nessee from 14 May to 9 September 1984. Twenty three of the 44 sites supported gastropods. Eight species of gastropods, Goniobasis laqueata, Physella gyrina, P. integra, P. heterostropha, Helisoma trivolvis, Ferrissia fragilis, Pseudosuccinea columella, and Gyraulus parvus, were found at various locations in 18 streams, one isolated spring, and three small lakes. Each collection site was sampled for species of gastropods and selected water chemistry characteristics, and geological features were noted. The presence or absence of the various snail species in the streams was correlated with the stream’s physical characteristics, water chemistry, and underlying geology. INTRODUCTION Little work has been done on the freshwater gastropods in western Kentucky, partly, per- haps, because of the confusing taxonomy result- ing from the great variability within what is referred to as a species, the need for taxonomic revision in several groups, and the distance from major universities and museums where gastro- pod research is currently being conducted. As a result, little is known about the ecology and distribution of species occurring in this area. Bickel (1) emphasized the need for collecting and publishing records of mollusks throughout Kentucky. Branson (2) provided a checklist with distribution records, and more recently Branson and Batch (3) summarized the distribution records of aquatic gastropods in Kentucky west of the Kentucky River. Burch (4) gave general distribution information for most of the aquatic gastropods known to occur in Kentucky. These recent papers significantly add to the knowledge of gastropod distribution in western Kentucky, but give little information regarding the eco- logical relationships of these gastropods; and, with an increasing interest in the endangered species (5), this information is sorely needed. Only 2 published records of gastropods in LBL could be located, one in which Branson and Batch (3) reported Lithasia verrucosa and Pleurocera canaliculatum from the shore of Kentucky Lake west of Golden Pond, Kentucky, and a report by Krieger and Burbanck (6) of Goniobasis semicarinata (= Goniobasis la- queata in this study) collected from Prior Creek by J.B. Sickel. Even less knowledge exists about gastropod ecological relationships in western Kentucky. Literature on gastropod ecology in other regions indicates that several factors are important in determining snail distribution. These factors include alkalinity and pH (7,8), substrate (9,10), vegetation (11), dissolved ox- ygen (10), temperature (12), and pollution (13). Land Between the Lakes provides two unique features that may be extremely impor- tant in future gastropod research. The land and streams remain relatively undisturbed, and the impoundments that form the east and west boundaries tend to isolate the tributaries form- ing impediments to migration of small stream gastropods, thus isolating closely related popu- lations. The undisturbed nature of the streams could be important in the conservation of rare species. The isolation of adjacent populations provides opportunities for studies in population genetics. DESCRIPTION OF THE STUDY AREA Land Between the Lakes is a national recreation area established in 1965. The area, approximately 65 km long and 12 km across (70,000 ha), is oriented north-south and is sur- rounded on 3 sides by water. The eastern boun- dary is formed by the Cumberland River (Lake Barkley) which was impounded in 1964, and the western boundary is formed by the Tennessee River (Kentucky Lake) which was impounded in 1944. A canal connects the 2 lakes and forms the northern boundary. Three counties, Trigg and Lyon counties of Kentucky, and Stewart county of Tennessee, include parts of LBL. Limestone and chert compose the primary geological formations found in LBL, and these Trans. Kentucky Academy of Science — 47(1-2) 7 formations determine the groundwater char- acteristics. St. Louis Limestone and Warsaw Limestone are both Mississippian formations that occur in LBL. Davis et al. (14) stated that water from wells drilled in the St. Louis Forma- tion in western Kentucky was hard to very hard, with 121 mg/1 or greater calcium carbonate, and water from Warsaw Limestone was also hard to very hard. Fort Payne Formation is also of the Mis- sissippian age. These rocks have been found to be less soluble than the Warsaw Limestone or the St. Louis Limestone. Groundwater from the Ft. Payne Formation is softer and has a lower mineral content (14). Cretaceous deposits overlie the Mississip- pian age formations of Land Between the Lakes. The basal unit of these Cretaceous deposits is Tuscaloosa Gravel. The McNairy Formation overlies the Tuscaloosa Gravel. Wells drilled in areas of McNairy Formation have produced soft waters where the underlying unit was thick and moderately hard to very hard waters where the underlying unit was thin (14). Alluvium deposits are from the Quaternary Period and are composed of silt, sand, and gravel formed from the weathering of the previously mentioned formations. The deposits may also contain various amounts of clay and are present along most stream valleys. These flood plain deposits of alluvium are generally too thin and fine to yield a significant amount of groundwater (14). Within Land Between the Lakes the streams flowing east to the Cumberland River are separated from those flowing west to the Tennessee River by a divide, approximately cen- trally located and extending the length of LBL. The short distance between this divide and either of the lake boundaries results in small drainage basins, and many of the streams have only ephemeral or intermittent flow. Several groundwater springs are present and are usually located on or near the few perennial streams in the area. Impoundments of 3 of these perennial streams and of a few embayments adjacent to Lake Barkley have created small lakes. Figure 1 shows the streams of LBL with those surveyed indicated by numbers. Stehr and Branson (15) showed that inter- mittent and ephemeral streams are subject to extremes of temperature, water volume, current velocity, and dissolved oxygen levels. Because of these changing conditions, species found in these streams are generally those that can withstand long periods of desiccation. Few freshwater gastropods are able to tolerate these extremes of conditions. Those belonging to the genus Physella, however, are able to survive by burrowing deep into the sediments during dry periods (16). In the present study, only the perennial and longest-lived intermittent streams of LBL were selected for collecting. These streams would allow more favorable conditons for mollusk communities to develop. Eighteen streams, 1 isolated spring, and 3 small lakes were selected for study. Collecting sites on each stream were chosen to reflect the influence of different underlyng geological for- mations, the presence of springs, and change in stream order. A total of 44 sites was surveyed. To compare conditions between the different stream systems, water chemistry sampling sites were selected at the most accessible points to allow sampling of all sites during a single day. MATERIALS AND METHODS The study was conducted from 14 May to 9 September 1984. Three times during the study period, a survey of all chemistry sampling sites was made to compare conditions occurring at each site. These sampling surveys were con- ducted after at least a week of dry weather to minimize the influence of surface runoff. All of the following water chemistry measurements, with the exception of turbidity, were performed on site. Dissolved oxygen and temperature were measured using a YSI Model 54 Oxygen-Tem- perature meter. Conductivity was measured with a Hach Model 2510 conductivity meter, and the pH values were determined with a Hellige Model 605-AHT color comparator and indicator solutions. Concentrations of calcium, total alkalinity, and hardness were determined using a Hack digital titration kit. Standardiza- tion of the titration method against a calcium standard solution, prepared as described in Standard Methods (17), gave results within 5% of the expected value. After the above para- meters had been analyzed, the water samples were kept on ice and transported to the Hancock Biological Station where turbidity was mea- sured with a Hack Model 16800 turbidimeter. After the chemical analysis had been com- pleted, physical characters of the streams were noted. These included the depth (m), the velo- city (slow, moderate or swift), the approximate area of the site exposed directly to incident sunlight, the primary substrate types, and domi- nant aquatic vegetation. Collecting of gastropods at each site was done using a dip net and by hand picking. Col- lecting was done qualitatively, picking until no new forms of gastropods were found. Specimens from different habitats, for example, pool areas or riffle areas, were kept in separately labeled containers. Collected snails were kept in water and transported back to the Hancock Biological 8 Freshwater snails in Kentucky—Blair and Sickle Station. The snails were first frozen and then perserved in a 5% glycerine-50% isopropyl alcohol solution. Identification of the gastropods was made using “Freshwater Snails (Mollusca: Gastro- poda) of North America” (4), and “Land and Freshwater Shells of North America Part IV Strepomatidae” (18). The identifications were verified by Dr. Billy G. Isom of the TVA labo- 0 Z ry Kentucky Lake (Tennessee River) 01 10 SSS aa SCALE OF km ratory at Muscle Shoals, Alabama. Voucher specimens are deposited in the mollusk museum in the Department of Biological Sciences, Mur- ray State University. Photographs were made of representative snails from each site and are included in the master’s thesis which resulted from this study. Geologic maps of each site are also included in the thesis (19). | N Lake Barkley 1 (Cumberland River) T 15, 16 17 18 Figure 1. Map of Land Between the Lakes showing surveyed streams. (1.)

Eleven of the 21 sites without mollusks were on streams that became dry during the study period. This sup- and alkalinity, high levels of turbidity and slow flow. The surface layer of substrate at each site was covered with a layer of silt and organic debris. Most sites also had a relatively warm temperature (20° C or above).

Other in- vertebrates and aquatic vegetation were also usually scarce in these intermittent streams. Eight gastropod species were found at the 23 collecting sites which supported gastropods. Several habitat characteristics, including cal- cium level, flow rate, temperature, and geo- logy, showed some relation to the species of gastropods found at particular sites. Table 1 isa summary of the species found in each stream along with selected chemical, physical, and geological characteristics of the streams. The planorbid snail, Gyraulus parvus (Say 1817), was found at 10 collecting sites. All these sites had moderate levels of calcium, hardness, warmer water (23-25° C) for reproduction and optimal growth rate. Species of Physella were found at numerous sites with various levels of calcium and other parameters. Physella integra (Haldeman 1841), however, was found only at 2 springs which had high levels of calcium and minerals and swift flow. Physella gyrina (Say 1821) was found at several sites on streams and lakes. The majority of these latter sites were characterized by the presence of heavy siltation and organic debris, and by slow flow. Where Physella gyrina was present in swiftly flowing streams, such as South Fork Panther Creek and Lost Creek, they were found in pool areas or areas of slower flow. These observations support the conclusions of Clampitt (20) who compared the ecology of Physella gyrina and Physella integra. He found 10 Freshwater snails in Kentucky—Blair and Sickel Physella integra to be a characteristic inhabi- tant of rocky lake shores but absent from ponds, while Physella gyrina was commonly found in both habitats. Physella heterostropha (Say 1817) has been reported by Wurtz (13) to be one of the most common and_ widespread _pollution- tolerant species. In this study, it was found in streams of various water chemistry levels, in areas of very low calcium concentration as well as in areas of high concentrations. Sites where Physella heterostropha was found also varied from swift to slow flow rate, and from little silt to heavy layers of silt and organic debris. Of the 3 species of Physella collected in the study, Physella heterostropha appears to be the most generalistic in habitat requirements. Pseudosuccinea collumella (Say 1817) was found at only one collecting site, Duncan Lake. Baker (21) described Pseudosuccinea columella as being found in quiet, stagnant habitats among cattails. These were the conditions pre- sent at Duncan Lake. Baker went on to say that although the lymnaeids are widely distributed in the United States, they are habitat restricted. The ancylid snail, Ferrissia fragilis (Tryon 1863), is also widely distributed in the eastern United States, but it is restricted to small bodies of standing water (4). Ancylids are particularly susceptible to desiccation because of their large aperture (22). Ferrissia fragilis was found at one spring-fed pool. The pool maintained a constant water level throughout the study period and showed no signs of probable changes in the future. Helisoma trivolvis (Say 1817) was found at only one spring site. It is common throughout North America (4). Goodrich (23) described Helisoma trivolvis as intrinsically adaptive since it lives in a variety of environmental conditions. Goniobasis laqueata (Say 1829) was found in 4 of the perennial streams which were primarily spring-fed. These streams had several features in common including swift to moderate flow rates, moderate to high levels of calcium, alkalinity, and hardness, moderately low levels of turbidity, moderately low temperatures, and little silt and organic debris. Some differences were found in the appear- ance of Goniobasis laqueata collected at dif- ferent sites. Those collected from the South Fork of Panther Creek were the most strongly sculptured, although specimens varied from almost smooth, to those having just spiral lines, to those with strong costae. Color also varied from a light greenish brown to a dark brownish black. Goniobasis laqueata collected at the headwaters of South Fork Panther Creek were generally slightly shorter and fatter with less sculpturing. Those collected from the con- fluence of the North and South forks of Panther Creek were longer and thinner, and had the strongest sculpturing. Goniobasis laqueata found at other sites on South Fork Panther Creek showed gradations between the two forms. Goniobasis laqueata collected from Lost Creek were generally dark in color and had less sculpturing. Those from Lost Creek at Hamm Hollow had the least amount of sculpturing. Those specimens were also found to have a heavy periphyton growth covering the shell. Goniobasis laqueata found at Crockett Creek were also dark in color. Those snails found upstream showed a moderate amount of sculpturing, but the majority were small in size. Specimens collected downstream were larger but with less sculpturing. Goniobasis laqueata from Crockett Creek also showed the most ero- sion of all gastropods collected during the study. The population of Goniobasis laqueata found at Prior Creek were devoid of any sculpturing and were light brown in color. The majority collected, however, had a dark brown color band that was not observed in specimens from any other creek. Although no obvious differences between the streams could be concluded as the cause of the variations in Goniobasis laqueata, habitat differences have been reported by other in- vestigators to be the cause of shell form changes. In the case of the streams of this study, perhaps the separation and isolation of the populations of Goniobasis laqueata have caused the divergence in appearance. In 1921, Goodrich (23) proposed that because Goniobasis is purely a creek form, any larger river can act as a barrier permitting the develop- ment of small distinct races. At most collecting sites, a clumped distribu- tion of gastropods was evident. This clumped distribution may have been the result of the habitat diversity and stratification at the collec- ting sites. Those sites with fewer species of gastropods had fewer habitat types than those sites where several species were found. It is doubtful that all the species of aquatic gastro- pods in LBL have been found since unsampled areas of streams and isolated ponds may have different habitat types and thus different gastropod species than those found. Differences in water chemistry between some of the sites was apparently related to the underlying geologic formations, and those dif- ferences influence the species of gastropods oc- curring at the sites (Table 1). Streams in areas of Tuscaloosa Gravel had lower levels of min- erals. Arlt Spring, in Tuscaloosa Gravel, showed calcium levels of under 10mg/1 calcium carbonate, while Lost Spring, which was of Trans. Kentucky Academy of Science — 47(1-2) 11 similar size and flow rate but in an area of Ft. Payne and Warsaw Limestone formations, had much higher calcium levels, 47-94 mg/1. Streams which were in areas of Warsaw Limestone, St. Louis Limestone or Ft. Payne for- mations showed moderate to high levels of min- erals. Those streams with groundwater springs showed higher levels of calcium than did streams without springs. Intermittent or ephemeral streams that flowed in areas of these formations still contained low levels of minerals, perhaps because these streams are more depen- dent on surface runoff than on groundwater for discharge. The results of this study indicate that the most important factors influencing the aquatic gastropod distribution in Land Between the Lakes are the duration of water availability and calcium levels in the streams. Intermittent streams of short duration and ephemeral streams do not appear capable of supporting gastropods even though at times these streams may have adequate flow and moderately high calcium levels. In perennial streams, calcium levels, food, turbidity and flow rate become more important as possible limiting factors. The variation in shell form between popula- tions of Goniobasis laqueata within the different streams of LBL illuminates the difficulties in molluscan systematics and provides material for future studies in taxonomy and population genetics. A detailed study of this variation would be useful for the taxonomic revision needed in the genus Goniobasis. ACKNOWLEDGEMENTS Sincere thanks are extended to Billy G. Isom, Carol B.

Helminth infections in red-eared turtles — Rosen and Marquardt ECOLOGICAL ASPECTS OF HELMINTH INFECTIONS IN CHRYSEMYS SCRIPTA ELEGANS (Wied) RON ROSEN, Division of Natural Sciences, Union College, Barbourville, Kentucky 40906 W.C. MARQUARDT, Department of Zoology-Entomology, Colorado State University, Fort Collins, Colorado 80523 ABSTRACT Thirteen species of helminths were recovered! from 94 red-eared turtles, Chrysemys scripta elegans, at Lake Conway, Arkansas. Turtles had an average of 246 helminths each. The relative abundance (RA) of the acanthocephalan, Neoechinorhynchus emyditoides (165.74) was greater than the RA values of all the other helminth species combined. The 3 remaining species of Neoechinorhynchus and the 3 nematode species recovered had RA values ranging between 0.88 - 16.62 and 12.28 - 31.00, respectively, while each of the 6 trematode species had RA values less than 1.70. The mean intensity of Spiroxys contortus was significantly greater in female than in male turtles. The prevalence of Heronimus mollis and S. contortus was significantly greater in younger male and/or female turtles. The mean intensity of S. contortus increased significantly in older female turtles, but the mean intensities of Camallanus trispinosus and Spironoura concinnae were greater in the younger age class of male and/or female C. s. elegans. The frequency distribution of 7 enteric helminths was determined from 12 intestinal sections of C. s. elegans. Camallanus trispinosus was most numerous in sec- tion 1 of the small intestine adjacent to the stomach, Neoechinorhynchus spp. (i.e., N. chrysemydis, N. emyditoides and N. pseudemydis) in section 3, Telorchis corti in section 5, Telorchis singularis in section 6 and S. concinnae in section 10 which represented the first section of the large intestine. These results are discussed with regard to the ecology of the parasite and the host. INTRODUCTION Studies concerned with helminth parasites of the red-eared turtle, Chrysemys scripta ele- gans, and other turtle species have usually been limited to work on surveys and life cycles in North America. Host sex, size and age have been seldom considered as factors affecting parasite prevalence and intensity with the ex- ceptions of Chrysemys picta marginata (1), Chrysemys scripta scripta (2), and Sterno- thaerus minor minor (3). In addition, reports dealing with the intestinal distribution of enteric helminths in turtles are few (4,5), and are impor- tant since they contribute to our knowledge of the physical and chemical requirements of these parasites. The objectives of this study were to deter- mine: 1) the effect of host sex and age on the prevalence and mean intensity of helminths found in C. s. elegans and 2) the frequency distribution of helminths in the intestine of C. s. elegans. MATERIALS AND METHODS Ninety four red-eared turtles were captured with a cylindrical fish basket from the Gold Creek Landing at Lake Conway, Arkansas 13 (T5N, R13W, Sec.32), from May 20 to August 4, 1977. All turtles were necropsied within 24 hours of their capture. Host sex and plastron length were recorded, after which the turtles were killed by an injection of ether into the brain. Plastron length is used in this study to give an estimation of host age since these 2 parameters are correlated; however, the sexes were considered separately since male and fe- male turtles of similar ages may have different plastron sizes (6). The intestine was removed immediately, placed in a dissecting pan filled with a 0.75% salt solution and its length measured. The intestine was then separated into 12 equal sections, and each section slit longi- tudinally and examined for helminths. Sections 1-9 represented regions of the small intestine, while sections 10-12 represented the large in- testine. The stomach, urinary bladder, lungs, liver, heart and gall bladder were also examined for worms. A listing of parasites and their location in C. s. elegans from this study was reported by Rosen and Marquardt (7). It should be men- tioned that the identification of the 4 acantho- cephalan species in the genus Neoechin- orhynchus was based on the eggs of mature female worms (8) due to the large number of 14 Trans. Kentucky Academy of Science — 47(1-2) specimens recovered. This technique made it necessary to assume that the male worms of each species occur in equal proportion to the females. Therefore, all calculations dealing with species in this genus represent estimations rather than exact values. Frequency distributions were determined for 7 helminth species in the 12 intestinal sec- tions of C. s. elegans. Statistical analysis was confined to parasite species with adequate sam- ple sizes. The terms prevalence, mean intensity and relative abundance are defined according to Margolis et al. (9). Chi-square contingency ta- bles (2 x 2) were used to assess differences in prevalence levels of 9 helminth species due to host sex and age blocking for sex. A Student’s t-test or Behrens-Fisher test assessed dif- ferences in the mean intensity of infection of 4 helminth species due to host sex and age block- ing for sex using log transformed data. Homogeneity of variances were tested with the F-max test (10). In all tests, a probability of 95% (P < 0.050) was considered to be significant. RESULTS All C. s. elegans in the present study were infected with at least 2 species ( X =4.8, range 2-10) of helminths, and a total of 13 species were recovered. Turtles had an average of 246 helminths each (range 16-1521). Relative abun- dance values for the 13 helminth species are given in Table 1. Table 1.

Female turtles, which were significantly larger than the males in this study (female plastron_ length - x = 15.7 cmvs. male plastron length -X = 13.3 cm, t=3.610, df= 92), had significantly more of the stomach nematode Spiroxys contor- tus than males (t = 3.090, df = 83). No other sex- related differences in prevalence or mean inten- sity were present for the other parasite species evaluated. The prevalence of the lung fluke Heronimus mollis was significantly greater in the younger age class of male (X?=5.796, df=1) and female (X?=4.218, df=1) turtles. The prevalence of S. contortus was also greater in younger male turtles (X= 5.164, df=1), but the mean intensity of this nematode increased significantly (t= 2.755, df= 42) in the older age class of female hosts. The mean intensities of the intestinal nematodes Camallanus trispinosus (t=2.483, df=43) and Spi- ronoura concinnae (t=2.199, df=28) were significantly greater in the younger age class of female hosts. The mean intensity of the former species was also significantly greater in the younger age class of male hosts (t=3.195, df = 47). No other host age-related differences in prevalence or mean intensity were present among the remaining helminth species. The frequency distributions of 7 enteric helminth species in the 12 intestional sections of C.s. elegans are summarized in Figure 1. C. trispinosus and the 3 species of Neoechinorhyn- chus were most numerous in sections 1 (77.8%) and 3 (37.1-41.4%), respectively. The trematodes Telorchis corti and_ Telorchis singularis were recovered with the greatest fre- quency from sections 5 (44.3%) and 6 (42.2%), respectively, while S. concinnae was most numerous in section 10 (69.2%). DISCUSSION The large number of helminth species recovered from C s. elegans at Lake Conway Arkansas, is probably indicative of habitat stability as discussed by Esch et al. (11) for parasites of C.s. scripta. Acanthocephalans and nematodes were the numerically dominant helminths indicating that large numbers of their intermediate hosts are ingested by C.s. elegans. The nematode and acanthocephalan species in this study (with the exception of S. concinnae) utilize copepods or possibly ostracods as in- termediate hosts in their life cycles (12,13,14). These zooplankton may occur in tremendous numbers, promoting the infection of many se- cond intermediate and/or definitive hosts. In contrast, snails and other macroinvertebrate in- termediate hosts of digenetic trematodes recovered in this study are probably less abun- dant than zooplankton. This smaller reservoir of intermediate hosts may have contributed to the low relative abundance of flukes in C. s. elegans. Helminth infections in red-erred turtles — Rosen and Marquardt 15 Table 2.

Kentucky Academy of Science — 47(1-2) Esch and Gibbons (1) attributed differences in the mean intensities of some helminths in male vs. female C. p. marginata to intrinsic dif- ferences between the sexes. Differences in the mean intensity of S. contortus in C. s. elegans due to host sex could be related to hormonal dif- ferences between the sexes or differential food requirements between male and female turtles. The latter assumes that the larger female C. s. elegans routinely ingest more of the macro- invertebrate, vertebrate and copepod in- termediate hosts listed by Hedrick (13) than the smaller male turtles over a given time to meet possibly greater nutrient demands. Several studies (15,16) have indicated that the degree of parasitism in turtles increases in relation to the size or age of the host. Both significant increases and decreases in the prevalence or mean intensity of several helmin- ths in relation to host age were observed in this study. The significant decrease in the prevalence of H. mollis in the older age class of male and female C. s. elegans has been reported for other trematode species in turtles (1,17). This trend, as stated in previous studies, is probably related to the differing food habits of juvenile and mature Chrysemys scripta. C. scripta juveniles are highly carnivorous and the adults are om- nivorous (18), the former thus consuming more of the macroinvertebrate intermediate hosts of trematodes. The life cycle of H. mollis is com- pleted by the ingestion of infected snails by turtles (19), and thus the smaller, juvenile turtles in this study would be expected to have a greater prevalence of infection with this worm. In addition, an age-related immune response cannot be ruled out as a possible factor con- tributing to the decreased prevalence of H. mollis in the lungs of older C. s. elegans. This reduction of trematode prevalence with an in- crease in turtle age does not support the general observation of Brooks and Mayes (20) that older turtles are more likely to be infected with platyhelminthes. Esch and Gibbons (1) found that the pooled nematode population of C. p. marginata (i.e., Camallanus microcephalus, S. contortus, Spi- ronoura sp. and Aplectana sp.) experienced a rise and fall in numbers in relation to host age. Separate consideration of the same or related species in this study showed that the mean in- tensity of S. contortus increased significantly in the older age class of female turtles, while the mean intensities of S. concinnae and C. tri- spinosus were highest in the younger age class of male and/or female C. s. elegans. It is unclear why younger female turtles had a significantly greater mean intensity of S. concin- nae than older female hosts. This nematode lives in the feces of the large intestine with no direct at- tachment to host tissues, and thus it is unlikely that an age-related immune response is involved. It is doubtful that documented differences in diet between young and old turtles play a significant role since S. concinnae has a direct life cycle (14). Perhaps other behavioral differences in female turtles associated with host age promote greater contact between young hosts and the infective lar- vae of S. concinnae. Further studies on the life cy- cle of S. concinnae and the behavior of C. s. elegans will be required to verify this. Spiroxys contortus and C. trispinosus uti- lize similar intermediate and transport hosts (i-e., copepods and aquatic vertebrates — 13,14) to com- plete their life cycles, and both nematodes live in the digestive tract of turtles where they are firmly attached to host tissues. However, the mean in- tensity of these 2 nematodes showed opposite trends with an increase in the age of female turtles. This may suggest that the life cycle of C. trispinosus has a greater dependence on vertebrate transport hosts for its completion than does S. contortus. This would account for the greater mean intensity of C. trispinosus in the younger, more carnivorous male and female turtles. Fur- ther work focusing on the relative importance of each type of intermediate or transport host in the life cycle of these 2 nematodes will be required for further insight into this problem. The intestinal habitats occupied by hel- minths in the present study were determined by numerous interacting factors which served to satisfy the physiological requirements of each parasite species. The concentration of C. tri- spinosus in intestinal section 1 corroborates the tindings of Uglem and Beck (5). They found that this parasite must live in the anterior part of the turtle intestine where APase activity is abundant since this nematode is unable to hydrolyze substances itself. In contrast, they found that Neoechinorhynchus emydis has a broad spectrum of APase activity. This may, in part, account for the more posterior concentration of Neoechinorhynchus spp. (i-e., most abundant in section 3) where APase activity would be less (5). It has been suggested that the location of telorchid trematodes posterior to the bile ducts (i.e., greatest frequency in sections 5 or 6 in this study) in the small intestine is related to their need to ac- quire essential substances from the host bile (21). The preference of S. concinnae for the large in- testine, where it lives in the lumen, supports Mackin’s (22) contention that the genus represents recent parasites which are similar to free-living species living in dung. The frequency distribution of enteric hel- minths should be specific for each host spe- cies, and therefore considered to be a stable biological characteristic, as demonstrated for the Helminth infections in red-eared turtles — Rosen and Marquardt nematode Trichinella spiralis (23). Recently, Ernst and Ernst (24) attempted to clarify the status of the turtle genus, Chrysemys, by using Sorenson’s Index of Similarity to compare endoparasitic helminths found in the species of this genus. They assumed that the parasites were biological characteristics of the host. In addition to this use of host specificity, comparison of frequency distributions of shared species of enteric helmin- ths in the Chrysemys complex may provide an ad- ditional biological characteristic for determining taxonomic relationships of turtles in this genus.

Ichthyoplankton in Ohio River — Simon VARIATION IN SEASONAL, SPATIAL, AND SPECIES COMPOSITION OF MAIN CHANNEL ICHTHYOPLANKTON ABUNDANCE, OHIO RIVER MILES 569 to 572 THOMAS P. SIMON Large Rivers Larval, Research Station P.O. Box 727 Grayslake, Illinois 60030 ABSTRACT Seasonal, spatial, and species composition of ichthyoplankton was investigated in 1983 in 3 main-channel stations on the Ohio River (River Mile 569 to 572). Specific objectives of this study were to determine the species composition of ichthyoplankton drift, to assess vertical distribution of taxa at 3 main-channel locations, and to consider temporal variations in abundance of fish eggs and larvae of main-channel species. Ichthyoplankton drift was composed of 19 distinguishable taxa distributed among 8 families. Dominant taxa included the Clupeidae, Cyprinidae, and Catostomidae. The majority of ichthyoplankton collected in the Ohio River was distributed near the surface, with a small percentage found in mid-depth and bottom samples. The average density of larvae obtained from 12 sampling dates, from 30 April to 24 August, was 2.42 larvae/m‘ for the locations combined. Two peaks were observed during 1983, with the maximum density of 16.06 lar- vae/m!* present on 25 June. INTRODUCTION The Ohio River has channeled waters of the midwest to the Mississippi River for over 200 million years. The present channel of the Ohio lies roughly at the edge of the southernmost ex- tension of the last glacial invasion of North America. The Ohio River valley has been drastically altered by man’s activities in the watershed (1, 2). The initial clearing of large sections of forests for agriculture and the increase in the human population has changed the physical, chemical, and biological constituents of the Ohio River. The Ohio River valley contains one of the worlds greatest coal-producing regions, 3 major metropolitan areas, over 40 power plants, and numerous other large industries. The Ohio River basin incorporates 8 states and 14 major river systems draining approximately 528,000 km’. The river carries over 150 million tons of waterborne cargo per year. During the 1970’s comprehensive studies designed to assess the impacts to early life- history stages of fishes from the operation of power plants and large industries were under- taken (3, 4) on the Ohio River. This paper presents data on patterns of larval fish abun- dance in 3 study locations within McAlpine Pool, a section of the Middle Ohio River. Such a study is basic to the understanding of main-channel utilization by larval fishes with regard to seasonal, spatial, and species variation trends. STUDY AREA AND METHODS The Ohio River has been converted from a free-flowing river with annual and seasonal 19 variations in flow, depth, and width, to a river of relatively constant width and a minimum chan- nel depth of 9 feet by the installation of a series of navigation dams. The basin-wide system of flood control reservoirs store flood water, and releases them slowly during the dry seasons, resulting in much lower flood crests, and much higher flows in late summer. The amount of rock, gravel, and coarse sand substrates have decreased, while increases have been observed in the amount of silt, fine sand and organic detritus. The construction of the navigation dams also inundated all of the original rapids and riffles of the river. The present study area, situated in northcen- tral Kentucky, encompasses Ohio River Miles (ORM) 569 through 572, part of McAlpine Pool (Fig. 1). Ichthyoplankton sampling was con- ducted at three study locations in the main channel of the Ohio River on 12 dates from April through August 1983. The study site was selected because of the species diversity, and previous ichthyoplankton sampling was con- ducted in the vicinity (5, 6). The 3 sites were selected based on observed differences in depth, river width, and substrate composition. Station 1, located 183 m upstream of Big Saluda Creek, represented the furthest upstream location (ORM 569). The substrate consisted of hard clay during April and May, and during August was composed of rock gravel, silt, fine-sand, and clay. Station 1 had depths ranging from 4 m to 5.5 m, and a shoreline that was primarily cut- bank. Station 2 was located 876.7 m below Lit- tle Saluda Creek near ORM 570.5, and was a wider section of the river forming a pool habitat. 20 Trans. Kentucky Academy of Science — 47(1-2) A permanent base of large cobble and boulders was present, while April substrates were mostly composed of fine sand, silt, gravel, and to a limited extent clay; May and August substrates were composed of silt and accumulated detritus. Station 2 was the deepest location with depths ranging from 6.8m to 8.0 m and had a shoreline composed of rock rip-rap and decidous forest. Station 3, located near ORM 572, represented the farthest downstream location. Substrates in- cluded a permanent base of large cobble and Figure 1.

JUNE JULY Stage, boulders, with fluvial substrates in April com- posed of hard clay; in May accumulated silt and detritus formed over the hard clay, while in August the substrate composition included gravel, clay, and fine sand. Depths at station 3 ranged from 5 m to 6 m, and bluffs lined the shoreline. Current velocities were equivalent at stations 1 and 3, with station 2 having the slowest current of the 3 areas. Biweekly samples were collected from each station during late afternoon from the 12 collec- tion sites. Samples were collected at main- channel locations at the surface, mid-depth, and 1 m off the river bottom at each of 3 stations using paired 0.5 m diameter, conical nets with 560 micron mesh. Near-bottom sampling was facilitated by a weighted anchor to prevent ac- cumulation of bottom sediments. Each tow was made 30 m off the Indiana shore in a upstream direction for a minimum of 5 minutes. A digital flowmeter was positioned in the mouth of the net to quantify the volume of water filtered. The volume ranged from 50 to 100 m*. Appropriate collection information was recorded, physical features (Fig. 2), and the sample preserved with 10% formalin. Data were analyzed by standard analysis of variance. RESULTS Taxonomic Composition Of the 9 distinguishable families in sam- ples, members of the Clupeidae, Cyprini- dae, and Catostomidae constituted 96% of the total catch (Table 1). Sciaenidae, Centrar- chidae, Hiodontidae, Percidae, and Percich- thyidae were sometimes common, but compos- ed only 4% of the total catch. Lepisosteidae was represented by a single individual.

SUMMARY The description and analysis of voter behavior on the Lextran referendum has exam- ined the spatial distribution of political attitudes. Behavior is a function of shared characteristics that are spatially patterned in the urban environ- ment, and the correlations between areal charac- teristics and voting patterns demonstrate some consistency between them. In the Lextran refer- endum, the differences in transportation demand are affected by the socioeconomic and demo- graphic factors indicated in social areas by the analysis. Areas that are most likely to contain transit dependents were also areas that sup- ported the Referendum. It is difficult to separate the effects of distance from the CBD as a poten- tial influence from the characteristics that in- dicate transit dependence because concentra- tions of people likely to use transit occur in com- munities near the city center. A definite dichotomy in suburban and inner city voting patterns does exist, and _ residential characteristics like lower percentage of home ownership and the presence of multi-family housing units do correspond with increased transit support. These correlations pose problems for the provision of public transit by electoral consensus. The use of the referendum process to decide an issue like transit support can be questioned when the service is of value to a minority within the community. In the Lextran referendum the in- equity of the electoral system in this decision making process is particularly biased. Lextran ridership surveys show that 80% of its riders are transit dependent, in terms of employment or other ride purposes; 37% own no automobiles; 66% of all riders are women, and 12% are elderly and handicapped. Presumably, these segments of the population will feel service cuts most of all; but because these persons are least likely to voice public opinion on the transit issue, they exert the least amount of control over the facility that they use most. As the federal government turns more transit programs over to states and localities, the interests of many minority groups will likely be ignored by the electoral process. LITERATURE CITED 1.

Courtship in Xiphorphorus — Hampton DISCRIMINATIVE COURTSHIP BETWEEN TWO DOMESTIC COLOR MORPHS OF XIPHOPHORUS HELLERII HECKEL (PISCES:POECILIIDAE) RAYMOND E. HAMPTON Laboratory of Animal Behavior and Behavioral Ecology, Department of Biology, Central Michigan University, Mt. Pleasant, Michigan 48859 ABSTRACT Males of the live-bearing poeciliid, Xiphophorus hellerii, preferentially court females of their own color morph when given a choice of females of their own or a different color morph. This discrimination is exhibited by males raised in single-morph groups as well as by males raised in mixed-morph groups, indicating that males do not learn this behavior by association with cohorts. INTRODUCTION Mating between different phenotypes of the same species is said to be assortative when it oc- curs between like phenotypes more often than would be expected if mating between pheno- types was random (1). This phenomenon is well documented in birds and seems to be a result of the young birds sexual imprinting on the parents (1,2). Assortative mating in nature may be advantageous in that it would tend to pre- serve local adaptations in populations. Fishes are not known to mate assortatively, even though many species of fishes are poly- chromatic. However, Kosswig (3) suggested that selective (assortative) mating might be an important factor in the apparent rapid specia- tion of the cichlid fishes of Africa, although there is no experimental evidence to support or reject this hypothesis. The experiments reported here were under- taken to determine if color strains of Xipho- phorus hellerii, produced through selective breeding, preferentially court members of their own color morph. X. hellerii, known among aquarium hobbyists as the “swordtail”, is a sex- ually dimorphic, ovoviviparous poeciliid which is indigenous to Mexico and Central America. Both sexes are promiscuous and mating is al- most constant. As in other poeciliids, males assume very active roles in courtship while the role of the female appears to be quite passive. There is no parental care by either sex after the female delivers the young. MATERIALS AND METHODS Species of X. hellerii of the “green” strain, which resembles the wild type in coloration, and of the “red velvet” strain, which is a uniform red color without the prominent lateral stripes of the wild type, were obtained from a local pet store. The fish were quartered in single-morph groups in 100 L aquaria at a temperature of 25 to 27 C with constant circulation and filteration of the water. They were fed once daily with commer- cial tropical fish food. Individuals of the green strain which were raised in a mixed-morph group were obtained by placing newly delivered green fry into an aquarium containing 2-day old red velvet fry. (Since the red fry were already two days old when the green fry were introduced, red fry were not used in experiments to determine the mating preference of males raised in mixed groups). Courtship preference of males was deter- mined by placing 2 green females and 2 red females into a 380 L aquarium and introducing test males one at a time. Each male was allowed to remain with the 4 females for 24 hours before observations were made. Following this ac- climation period, the frequency of “backing displays” made by the male to either green females or red females in a period of 1 hour was recorded. The “backing display” is a species- specific courtship display in which the male darts rapidly about the female with his fins fully extended and often attempts to touch the female with the long extension of his caudal fin (the “sword”) while swimming backward toward her. The paired t-test (4) was used to test for significance in differences between the frequency of courtship displays directed by males to females of like and unlike morphs. Six males of each group (green and red males raised in single-morph groups and green males raised in mixed-morph groups) were used. RESULTS AND DISCUSSION Green males raised in single-morph groups, red males raised in single-morph groups, and green males raised in mixed-morph groups all 35 36 directed significantly more courtship displays to females of their own morph than to females of the opposite morph (Table 1). Sexual imprinting on the parents seems unlikely in this species, since there is no parental care period and, in fact, parents represent a threat to fry and are avoided. Imprinting on cohorts as a mechanism for later sexual identification also seems un- likely, since green males raised in mixed-morph groups were exposed from birth to both green and red females of their own age group. The possible relationship of discriminative courtship based on phenotype to assortative mating is obvious and needs no elaboration. Genetic experiments are now being conducted to determine the extent to which such discrimina- tion in courtship leads to assortative mating among color morphs of X. hellerii. SUMMARY Males of the “green” and “red velvet” vari- eties of the swordtail, Xiphophorus hellerii, preferentially court females of their own morph when given a choice of females of both morphs. Males discriminate regardless of whether they were raised in single-morph groups or in mixed- Trans. Kentucky Academy of Science — 47(1-2) morph groups. Such discrimination is expected to result in assortative mating.

Green River fishes, Kentucky — Weddle FISHES OF THE GREEN RIVER DRAINAGE IN TAYLOR COUNTY, KENTUCKY by GORDON K. WEDDLE Department of Biology Campbellsville College Campbellsville, Kentucky 42718 ABSTRACT A systematic survey of streams in the Green River drainage, Taylor County, Kentucky was conducted to determine the current ichthyofauna and to examine the influence of physiography on the distribution of fishes. Forty three species and 3 sunfish hybrids were collected from 41 sites. Combination of these data with data from previous studies indicates a current Taylor County Green River ichthyofauna of 69 species. Distributional records for 5 species of fishes are reported. Ericymba buccata, the silverjaw minnow was collected for the first time in the upper Green River. Presence of this species is likely due to a stream capture exchange with the Roll- ing Fork drainage in Casey County. Nine species exhibited localized distributions within the survey area (P<0.02). Two distinctive fish faunal assemblages occur in Taylor County: the first inhabits the Eastern Pen- nyroyal Province; the second inhabits the Knobs Province and is isolated from the remainder of the Green River drainage by Green River Reservoir. It is probable that these faunal differences reflect the impact of Green River Reservoir on Knobs communities of fishes but possible that distributions may be influenced by physiography. INTRODUCTION Taylor County is located near the geo- graphic center of Kentucky and contributes significantly to the watershed of the Upper Green River. The only distinctive physiographic boundary of the country is the Muldraugh Escarpment, which forms the southwestern rim of the outer Bluegrass Region and the divide between the Green and Salt river drainages. The county is approximately 736 km’ in area and is characterized by rolling uplands dissected by relatively flat stream valleys typically aligned in a southwesterly direction. Two distinct physiographic regions are pre- sent in Taylor County. Most of the central and western portions of the county are included in the Eastern Pennyroyal, characterized by Mississippian strata of the Salem-Warsaw and Fort Payne limestone formations. In contrast to the Pennyroyal, the Knobs Province, which cuts across the northeastern corner of the county, is underlain by shales of the New Province and New Albany formations that are of Lower Mis- sissippian and Devonian ages, respectively (1). In 1969, a flood control dam was con- structed on the Green River in Taylor County, forming Green River Reservoir, a 12,950 ha lake. Approximately one-half of the lake falls within the boundaries of Taylor County. The re- mainder is located in adjoining Adair County to the southeast. Most of the streams that flow 37 through the northeastern Knobs Province of Taylor County are tributaries of Robinson Creek which now merges with the reservoir several km upstream from its pre-impoundment confluence with Green River. This river flows from the res- servoir and across the southern tip of Taylor County, then southwesterly through Green County. The principal stream system within the Eastern Pennyroyal is the Big Pitman Creek drainage. This stream is tributary to Green River in Green County. The fishes of the Upper Green River have been the subject of many studies, including the historically important early works of Rafinesque (2) and Woolman (3). More recently, biologists have examined the effect of point-source pollu- tion of the Pitman system (4,5,6), the effect of impoundment on the fishes of the Green River (7), the sport fishery potential of a number of sites (8 and B. D. Laflin, pers. com.) and the water quality and aquatic biota of the oil shale region in the Knobs Province (9). However, no systematic survey of the stream ichthyofauna of Taylor County has been completed. Accordingly, this study was undertaken to document the occurrence and distribution of stream fishes in Taylor County and to examine the possibility that fish distributions within the county might be influenced by the presence of two distinct physiographic regions. 38 Trans. Kentucky Academy of Science — 47(1-2) MATERIALS AND METHODS Fishes were sampled from 27 August 1982 through 27 August 1983. One additional site was sampled in March of 1985. No samples were taken during January or February of 1983. A total of 43 samples were collected from 41 locations. Fourteen sites were sampled in the Knobs Province and 27 sites were sampled in the Eastern Pennyroyal Province (Fig. 1). No at- tempt was made to sample either the Green River Reservoir or its tailwaters. Initially, fishes were collected with minnow seines of 5 mm? mesh. However, all later collec- tions were made using a backpack elec- troshocker (10). Representative specimens of each species were fixed in 10% formalin in the field and returned to the laboratory for final storage in 35% isopropanol. Identifications were performed using both published and un- published keys of several authors (11-16). A Pennyroyal Province Taylor County, Kentucky tinct assemblages of fishes occur within the county. Fisher’s Exact Test was used to calculate probabilities (two-tailed) that in- dividual species of fishes were equally distributed between the Robinson and Pitman drainages. Data for all species occurring at two or more sites were examined using a FORTRAN program (17:731) and an IBM PC computer. Data from this work have been recorded on permanent computer files that also contain fish, macroinvertebrate and physicochemical data from other sites within the Upper Green River basin. These efforts may, in time, provide a significant data base for the aquatic biota of central Kentucky. RESULTS A total of 43 species and 3 sunfish hybrids in 12 families was identified during this survey. Table 1 lists species and collection localities.

Pimephales promelas, E. stigmaeum and E. zonale were characteristic rare taxa. Several of the remaining taxa, which occurred at frequen- cies of 10-50%, demonstrated localized distribu- tions within the county, being much more pre- 39 valent in one or another of the 2 major physio- graphic regions (Table 2). Results of statistical analyses of distribu- tional data are included in Table 2. The null hypothesis was that species of fishes were dis- tributed equally between the Western Penny- royal and Knobs provinces. Nine species (21% of the fauna) exhibited unequal distributions (P < 0.02; Table 2). Calculated probabilities for several other species, including Esox ameri- canus (P = 0.0683), Etheostoma caeruleum (P = 0.0830), E. flabellare (P ='0.0506) and E. spectabile (P = 0.0756), may represent real dif- ferences in distribution, but additional collec- tions would be necessary to verify this. Although many species were randomly distributed within the county, fish assemblages inhabiting the 2 physiographic provinces are distinctly different. Ericymba_ buccata, Notropis_ spilopterus, Etheostoma barbouri and Percina caprodes characterize the fauna of the Robinson drainage in the Knobs Province; Catostomus commer- soni, Cottus carolinae and Etheostoma rafines- quei characterize the fauna of the Pitman drainage in the Eastern Pennyroyal Province. Because the potential effect of fish migration was not assessed, additional sampling might alter these conclusions.

Charles (4) and Hoyt and Robinson (7) made the most extensive collections of Taylor County fishes prior to this study. Charles re- ported 57 species from Green River and 48 40 species from Big Pitman Creek during 1960-63. Hoyt and Robinson collected 45 species in the Green River tailwater in 1978-79. Most of the species that were collected by these authors yet absent from my samples were riverine cyprinids and percids. This was expected because large- river habitats were not sampled. Combination of data from this paper with earlier surveys indicates that the current Taylor County fish fauna consists of 69 species. Eight additional species, collected by Charles (4), have not been reported since the impoundment of Green River. Four of these may still inhabit Big Pitman Creek, but the remainder, which were originally found only in the tailwater reach of Green River, have likely been extirpated (7). New collection localities for 5 species of fishes are reported here (Table 1). Most notably, Ictalurus melas and Ericymba buccata had not been previously reported from Taylor County, although I. melas has been collected in both Big Pitman Creek and Green River in adjoining Green County (4). Ericymba buccata, the silverjaw minnow, occurred in 57% of the sampling sites in the Robinson Creek drainage and was commonly the most abundant cyprinid. Previously, this minnow was known in the Green River only from its extreme lower reaches in western Kentucky (19, 20). Subsequent collections by Kentucky Nature Preserves Commission biologists have substantiated the presence of this fish in Robin- son Creek (9). The occurrence of E. buccata in the Upper Green River is enigmatic. Wallace (21), in an at- tempt to explain the overall distributional pat- tern of this species, hypothesized that either it never occupied the Green River or that popula- tions formerly inhabiting the drainage had undergone recent extinction. The discovery of the silverjaw in the Upper Green River could be construed as supportive of the latter. However, it is equally possible that the Taylor County population is the result of recent introduction from a stream capture exchange with the Roll- ing Fork River (Salt River drainage) or from a bait release. Faunal exchanges have been sug- gested between the headwaters of the Dix and Rolling Fork rivers in Boyle County (22). Head- waters of Green River occur near the same area. Although Harrison Garman collected fishes from Robinson Creek in the late 1800's, his samples (Mus. Comp. Zool., Harvard) were in- complete and did not include E. buccata. Unfor- tunately, other samples of historical value, that predate the impoundment of Green River, do not exist for Robinson Creek, and conclusions regarding the disjunct distribution of E. buccata in Kentucky are speculative. Comparative mor- phometric and electrophoretic studies of Ken- Green River fishes, Kentucky — Weddle tucky populations of the species would possibly clarify distributional history. The Knobs Province assemblage of fishes, of which E. buccata is a member, is a distinctive fauna. Five species occurred in more than 10% of the samples in the Robinson drainage but were absent from Big Pitman samples. Con- versely, excepting rare taxa, only 3 species were unique to the Big Pitman drainage (Tables 1 and 2). One site, Black Lick Creek, in the Knobs Province supported the most diverse community of the study (26 species). Fishes occurring within streams of the Robinson Creek drainage are isolated by the reservoir from those in the Pitman Creek drain- age of the Eastern Pennyroyal. The reservoir might also act selectively to filter the dispersal of fishes from the Knobs Region to the upstream reaches of Green River. This, coupled with dif- ferences in bedrock geology and water chemi- stry between the Pitman and Robinson drain- ages (9 and unpublished data) and the poten- tial effect of the impoundment on the Robin- son drainage, suggests plausible explanations for the localized distributions of Taylor County fishes. Studies of the impact of impoundments on fish community composition have concentrated principally on alteration of the tailwater environ- ment to explain faunal differences upstream and downstream (7, 23). However, it is possible that restrictions on fish migratory movements and certain physical changes in the habitat, such as increased siltation, channel encroachment (24) and instability of flow, mediated by fluctuating reservoir levels, probably alter the composition of upstream fish communities as well. An in- crease in number of fishes that can tolerate len- tic environments in streams above impound- ments is expected (25). The increased frequency of Micropterus punctulatus (P = 0.0199), Etheostoma barbouri (P = 0.0013) and Percina caprodes (P= < 0.0001) in Knobs Province streams, relative to Eastern Pennyroyal streams, is supportive of this idea. Lotic habitats upstream from impound- ments are essentially insular in character and the importance of various limiting factors is, by and large, dependent on the amount of usable habitat in the isolated watershed. During per- iods of stress, such as prolonged drought, the amount of usable habitat could become limiting as species aggregate in pools. Under such con- ditions selection would favor eurythermal species that are also tolerant of reduced oxygen concentration. Inbred gene pools in isolated populations of fishes may predispose certain habitat restricted species to extinction (26). Current data are insufficient to allow a con- clusive explanation of the origins of the distinc- Green River fishes, Kentucky — Weddle tive fish assemblage inhabiting the Knobs Pro- vince of Taylor County. It is likely that the fauna reflects alteration of habitat caused by the im- poundment of Green River, but it is also possible that the Knobs assemblage is, in part, a relict assemblage adapted to a unique geologic and physicochemical environment. Comparative ecological studies of shale and limestone streams in the Green River drainage in Casey County are ongoing and should add to our understanding of the dif- ferences in these habitats. The results of this project indicate that future pre-impoundment studies should include examinations of low- order streams that will be isolated by the im- poundment.

Sandstone dikes in Kentucky — Cox and VanArsdale PETROGRAPHIC STUDY OF THE VALLEY VIEW AND CLAY‘S FERRY SANDSTONE DIKES IN EAST—CENTRAL, KENTUCKY by J. MACKLIN COX Ohio-Kentucky Oil Corporation 3060 Harrodsburg Road Lexington, Kentucky 40503 ROY B. VANARSDALE Department of Geology University of Arkansas Fayetteville, Arkansas 72701 ABSTRACT Studies of thin-sections and slabs of the Clay’s Ferry and Valley View sandstone dikes in east-central Ken- tucky were undertaken in order to determine their petrology and emplacement mechanism. In addition, grain- mounts of the Irvine Formation sands of Pliocene-Pleistocene age were analyzed to determine if they were a possible sediment source for the dikes. The sandstone dikes consist of well-sorted, angular to well-rounded, calcareous quartz arenite apparently derived from the same sediment source. Petrographic analysis of the two sandstone dikes and the Irvine Forma- tion suggest that the dike sands were not derived from the Irvine Formation. Flow structures in the Valley View dike indicate that emplacement occurred through forceful injection of sediment in a hydroplastic state. The sand in the Clay’s Ferry dike appears to have been emplaced by forceful in- jection from above the dike’s roadcut exposure. Therefore, sands of Mississippian and Pennsylvanian age are considered most favorable as a sediment source for the two dikes but an underlying Ordovician sand source can not be discounted. Minor reactivation of the Kentucky River fault appears to have occurred after the emplacement and cemen- tation of the Valley View dike. Cross-cutting relationships within the Valley View dike reveal that south-dipping normal faults have been displaced by north-dipping reverse faults. INTRODUCTION Two sandstone dikes were studied along the Kentucky River fault zone in east-central Ken- tucky (Fig 1). One dike is located in northern Madison County at Clay’s Ferry and the other extends from southwestern Fayette County into southeastern Jessamine County near Valley View. The Clay’s Ferry dike is exposed in a road- cut along U.S. 25 (Fig.2) and the Valley View dike is exposed in a roadcut along Kentucky 169 (Fig. 3). McFarlan (1,2) concluded that the Clay’s Ferry and Valley View dikes consist of fluvial sands of either Pennsylvanian or Pliocene- Pleistocene age that washed into earthquake fissures resulting from late Paleozoic or Tertiary movement along the Kentucky River fault zone. McFarland (1,2) favored the interpretation that the sand was derived from the Pliocene- Pleistocene Irvine Formation which was washed into Pliocene-Pleistocene earthquake fissures. Rieke and King (3) postulated that the dikes are solution-widened joints filled with sediments washed in by the Pliocene-Pleistocene Kentucky River. More recently, Tillman (4) described a sandstone dike exposed in a trench 2 km east of Valley View which appears to be related to reac- tivation of the Kentucky River fault. The dike mapped by Tillman appears to have been in- jected from below (4). If these dikes are indeed earthquake fissure fillings, as proposed by McFarlan (1,2), or have been emplaced coincident with fault reactiva- tion, as proposed by Tillman (4), then they may reflect Pliocene-Pleistocene reactivation of the Kentucky River fault zone. The purpose for this study was, therefore, two fold: (1) to determine if 43 44 Trans.

THE KENTUCKY RIVER FAULT ZONE The Kentucky River fault zone is a portion of a discontinuous east-west fault system which extends from southern Illinois (Shawneetown fault) through western Kentucky (Rough Creek fault), then across eastern Kentucky (Kentucky River fault zone) into West Virginia (Woodward fault) (Fig. 1) (5,6). The Kentucky River fault zone cuts across the east limb of the Cincinnati Arch and is the northern boundary fault of the Rome Trough (7). The Rome Trough has, in turn, been interpreted to be part of an east- trending aulacogen of Late Precambrian and Palezoic age (7,8). is to the left. The surface expression of the Kentucky River fault zone varies along its trace in the study area near Lexington, Kentucky (Fig 1.). The fault zone is a maze of faults within a major linear graben in the Ford quadrangle (9). Far- ther west, in the Valley View quadrangle, the fault zone is an asymmetric graben with the ma- jor displacement on the north fault.(10). The sense of movement along the Kentucky River fault zone has been cited as right lateral, left lateral, reverse, and normal. The diversity of sense of displacement is the consequence of recurrent movement from Precambrian through Pennsylvanian time (5,6,11,12,13). Late Pre- cambrian, right lateral offset and early Cam- brian normal displacement have been reported (14,7,5). Maximum normal displacement oc- curred during mid-Cambrian time (7). Minor ac- tivity continued in the Ordovician, Silurian, and Devonian periods with larger normal displace- ments in the Upper Mississippian and Pennsyl- vanian periods (15,12,7). The total down-to- the-south displacement at the top of the Pre- cambrian is approximately 457 m in the area of figure one (7); however, the Ordovician-to Mississippian-age rocks are vertically displaced down-to-the-south an average of 61 m with a maximum of 183 m at Burdette Knob (13). Due to the absence of Mesozoic and Lower Tertiary stratigraphy in eastern Kentucky, it has not been possible to determine if there has been iN ue Figure 3. The sandstone dike at Valley View. North is to the left. recurrent fault movement during Mesozoic and Early Tertiary time. However, Tertiary move- ment has been suggested based on geomorphic evidence (2,16). Jillson (16) proposed that the anomalous southwest bend in the Kentucky river near Winchester, Kentucky, is due to diver- sion during Early Tertiary reactivation of the Kentucky River fault zone. McFarlan (2) propos- ed that sandstone dikes at Clay’s Ferry and Valley View (Fig 1) consist of sand derived from high-level Kentucky river terraces of Late Ter- tiary age. As discussed above, the dikes were 46 Trans. Kentucky Academy of Science — 47(1-2) proposed by McFarlan to be the filling of earth- quake fissures formed by Late Tertiary reactiva- tion of the Kentucky River fault zone. More re- cent studies by VanArsdale and Sergeant (17) have revealed folded and faulted Pliocene- Pleistocene Kentucky River terraces (Irvine For- mation) which suggest Pliocene-Pleistocene reactivation of the Kentucky River fault zone. ORIGIN OF CLASTIC DIKES Clastic dikes (of which sandstone dikes are one type) are cross-cutting, tabular-shaped bodies of clastic sediment created by the filling or injection of sediment into fissures (18). Clastic dikes do not create the fissures in which they are contained; therefore, fissures are created by another, perhaps related, mech- anism before clastic dikes may be emplaced 19,20). The fissures may be filled with clastic sediment through two mechanisms: (1) from above by wind, water, or gravity; or (2) from above or below by forceful injection (21,22). The structures developed within a dike de- pend upon the emplacement mechanism and/or the properties of the sediment during emplace- ment. Dikes emplaced through infilling from above by wind, water, or gravity generally show some degree of horizontal stratification (21,23) and a considerable range in composition and texture (21,24). When a dike is emplaced through forceful injection, the resulting struc- tures depend upon the properties of the sedi- ment during injection. Sediment injected in a hydroplastic state is thought to occur under laminar flow conditions (25). Flow structures within the dike form as a consequence of these laminar flow conditions (18,25,26,27). These structures include oriented grains, banding, scour marks, rod structures, and crushed and split-mica folia. Dikes emplaced through forceful injection of sediment in a liquefied state are generally massive and well sorted, and then become finer grained with increasing distance from their source (28). METHODS Both dikes were sampled at their roadcut exposures on Kentucky 169 and U.S. 25. Five thin sections were prepared for petrographic study, two from the Valley View dike and three from the Clay’s Ferry dike. Two slabs were cut from the Clay’s Ferry dike and 3 were cut from the Valley View dike. All slabs were cut perpen- dicular to the strike of the dike. Three samples of the Irvine Formation (Kentucky River terrace sediments of Pliocene- Pleistocene age) were obtained from 2 locations (Fig 1). One sample was collected at Sand Hill, Kentucky, from a foundation excavation. The other 2 samples were collected in southern Clark County by TenHarmsel (30) using a truck- mounted auger rig. The auger samples were col- lected from 4 to 6 meters below the surface. Clay layers above the sample depths assured relatively fresh samples. A grain mount was prepared from each Irvine sand sample for petrographic analysis. RESULTS CLAY’S FERRY DIKE The dike at Clay’s Ferry (Figs. 1 and 2) is approximately 5 cm thick, strikes north 75° east, and dips approximately 85° to the north- west. The dike is contained within the Lexington Limestone and is approximately parallel to, and 61 m south of a major eastward trending fault of the Kentucky River fault zone. The fault at Clay’s Ferry has 76 m of down-to-the-south displacement (9). PETROGRAPHY OF THE CLAY’S FERRY DIKE The Clay’s Ferry dike is a well-sorted, angular to well-rounded, calcareous quartz arenite. The framework elements consist of 94% monocrystalline quartz, 2% polycrystalline quartz, 1% microcline, 2% rock fragments, and trace amounts of plagioclase, muscovite, biotite, zircon, glauconite, and opaques. Clay matrix occurs only in trace amounts and the dike is cemented with sparry calcite (17%). The monocrystalline quartz was initially subrounded to rounded, although replacement by calcite has produced irregular grain boun- daries. Some quartz grains contain vacuoles, bubble trains, microlite inclusions, and negative crystals. Much of the polycrystalline quartz is also partially replaced with calcite. Grains of this quartz variety are subrounded to rounded, and many have crenulated internal boundaries. A majority of the microcline grains are generally fresh, although some display a high degree of alteration to clay minerals. Most microcline grain boundaries are replaced with calcite. In addition, highly weathered plagioclase grains were found in one sample. Biotite and muscovite are present in all samples. The biotite ranges from relatively fresh flakes to flakes almost completely altered to chlorite. Glauconite occurs as green micro- crystalline, elliptical pellets. Rock fragments include chert, shale, and possibly schist. The Sandstone dikes in Kentucky — Cox and VanArsdale 47 chert grains are rounded and partially replaced with calcite. The dike consists of well-sorted, angular to well-rounded grains. The finer grains appear to concentrate along the walls of the dike and there is a tendency for the long axis of grains to be oriented vertically throughout the dike. SLAB DESCRIPTIONS OF THE CLAY’S FERRY DIKE Slab 1 from the Clay’s Ferry Dike, was cut from a sample collected at the basal exposure of the dike and revealed that the dike is separated into one main body and two subsidiary bodies (Fig. 4). The 3 bodies are oriented vertically and display no apparent structures within the dike rock. The dike walls consist of a skeletal grainstone in the upper portion of the slab and skeletal packstone in the lower portion of the slab. Tabular-shaped wall fragments occur within the dike rock. One fragment, a skeletal grainstone, appears to have originated from the upper portion of the slab and was moved downward within the dike to the lower portion of the slab (Fig. 4). Slab 2 from the Clay’s Ferry Dike was cut from a sample collected 1 m above the first slab. Here, the dike rock lies between 2 roughly, parallel walls of skeletal wackestone (Fig 5). The wall rock is split and a thin layer of sand penetrates approximately 4 cm into the enclos- ing limestone (Fig 5). Concave-upward, trough- shaped structures occur within the main body of the dike. VALLEY VIEW DIKE The Valley View dike (Figs. 1 and 3) varies from 15 to 23 cm in thickness, strikes north 70° east and dips 85° to the northwest. The dike lies along the plane of the Kentucky River fault with the Tyrone Limestone on the north and the down-thrown (30 m) Lexington Limestone on the south (10,31). The dike rock weathers to produce smooth, wavey, vertical surfaces which are generally parallel to the dike walls (Fig. 6).

The framework elements consist of 94% monocrystalline quartz, 2% polycrystalline quartz, 2% chert, 1% microcline, and trace amounts of muscovite, zircon, glauconite, and opaques. Clay matrix is present only in trace amounts and the dike is cemented with sparry calcite (15%). The monocrystalline quartz grains were ap- parently subrounded to rounded, but replace- ment by calcite has produced irregular grain boundaries. Some of the quartz contains vacuoles, bubble trains, and microlite inclu- sions. A minor amount of the quartz is fractured with the factures displaying no apparent pre- SLAB DESCRIPTIONS OF THE VALLEY VIEW DIKE Slab 1 from the Valley View dike has ir- regular surfaces that are roughly parallel to the walls of the dike (Fig. 7). Many of these surfaces join thus forming sediment enclosures. The sedi- ment varies in color and/or concentration of wall fragments across several surfaces. Slab 1 is also crossed by two sets of frac- tures both of which contain calcite veins. One set dips southward approximately 60° and the other set dips northward approximately 65°. Reverse fault movement is indicated along the Figure 6. Apparent flow structures within the Valley View dike at its roadcut exposure. North is to the left. ferred orientation. The fractures are filled with calcite. The polycrystalline quartz is subrounded to rounded and many exhibit crenulated internal boundaries. The microcline, which is relatively unweathered, is almost completely replaced at the grain boundaries by calcite. Zircon occurs as round to elliptical grains and glauconite occurs as green microcrystalline elliptical pellets. Many of the chert grains, which were originally rounded, are almost completely replaced by calcite. There is a tendency for finer grains to concentrate at indentations in the wall rock. Many of the elongated grains are oriented _ver- tically and parallel to the dike walls. Figure 7. Slab 1 from the Valley View dike (cut perpendicular to dike walls) showing irregular sedi- ment enclosures and calcite-filled fractures. The calite vein at A is displaced 0.25 millimeters. North is to the left. northward-dipping fractures by the 2.5 mm displacement of the southward-dipping veins (Fig. 7). Slab 2 contains thin layers which parallel the dike walls (Fig. 8). These structures are more planar and continuous than those found in slab 1. The layers have formed from the parallel alignment and sorting of grains. This is in- dicated by an obvious alignment of muscovite folia and a smooth, wavey parting of the dike rock parallel to the layering (Fig. 6). Two sets of calcite-filled fractures, which have southward and northward dips of approximately 15° and 35°, respectively, cut sample two. Although not Sandstone dikes in Kentucky — Cox and VanArsdale readily visible in Figure 8, normal fault move- ment has occurred along the southward-dipping fractures, as indicated by an apparent 1.2 mm displacement of the vertical flow layers. The northward-dipping fractures show reverse fault movement and have displaced both the vertical flow layers and the southward-dipping fractures approximately 3.8 mm. Slab 3 exhibits well-developed vertical layering along the northern edge of the dike (Fig. 9). The layers are nearly parallel to the dike walls and reflect parallel alignment and sor- ting of grains. One layer contains numerous elongated carbonaceous fragments that are Figure 8. Slab 2 from the Valley View dike (cut perpendicular to dike walls) showing layered struc- tures parallel to the dike walls and calcite-filled frac- tures at A and B which have been displaced by faulting. North is to the left. generally aligned parallel to the dike walls. The interior portion of the dike appears massive; however, close inspection reveals muscovite folia aligned parallel to the dike walls. The dike rock parts along smooth, wavey surfaces which apparently result from the general alignment of elongated and platy grains parallel to the part- ing. In the upper portion of the slab the dike rock is fractured into blocks which are enclosed in a matrix of limestone breccia. The minimum vertical displacement between the blocks and the undisturbed dike is 2.5 cm. The fracturing 49 and vertical movement of the dike rock occurred after the dike’s emplacement and cementation. PETROGRAPHY OF THE PLIOCENE- PLEISTOCENE IRVINE SANDS Petrographic study of the Pliocene- Pleistocene Irvine sands revealed a_ super mature, ferruginuous, quartz arenite (32). The framework elements consist almost entirely of well-sorted, subangular to subrounded monocrystalline quartz. Muscovite, zircon, tour- maline, and shale fragments are present in trace amounts. Iron oxide occurs as a thin coating on most grains. Figure 9. Slab 3 from the Valley View dike (cut perpendicular to the dike walls) showing well- developed layered parallel to the dike walls at A, and fractured blocks of dike rock floating in a matrix of limestone breccia at B. North is to the left. DISCUSSION The framework elements of the Clay’s Ferry and Valley View dike sediments are very similar, which suggest that they were derived from the same sediment source. Monocrystalline quartz, polycrystalline quartz, microcline, chert, zircon, muscovite, and glauconite occur in the same concentrations in each dike and represent greater than 99% of the framework elements. The only framework components of the 2 dikes that do not directly correlate are trace amounts 50 of plagioclase, biotite, and rock fragments pre- sent only in the Clay’s Ferry dike. However, biotite and plagioclase may be absent in the Valley View dike because they have been com- pletely altered to clay. The shale fragments, which are not present in every thin section of the Clay’s Ferry dike, may be derived from the wall rock. If this is true, then the shale fragments would have an uneven distribution and may be limited entirely to the Clay’s Ferry dike. The Irvine Formation sands are signifi- cantly more mature than the sand of the dikes. The Irvine Formation samples consist entirely of highly resistant minerals, namely monocrystalline quartz, zircon, tourmaline and muscovite. Exposure of the Irvine Formation to chemical weathering since deposition is un- doubtedly a contributing factor in producing these super mature sands. If the sand of the dikes represents relatively unweathered Irvine age sands, then the Irvine Formation would represent a weathered residue of these dike sands. Therefore, the chemically stable minerals present in the dikes should also be present in the Irvine Formation. The dikes contain an average of 2% polycrystalline quartz and 2% chert fragments. It is unlikely that these highly resis- tant minerals would be removed from the Irvine Formation through chemical weathering. These quartz varieties were not found in the Irvine For- mation sands studied during this investigation. Cantrell (32) also noted an absence of poly- crystalline quartz and chert in the Irvine Forma- tion. Consequently, it appears unlikely that the dikes consist of Irvine Formation (Pliocene- Pleistocene) sand. If the Irvine Formation is not the sediment source of the dikes, then other sand bodies must be considered as possible sediment sources. The Saint Peter Sandstone and the Rose Run For- mation, both of Ordovician age, lie approx- imately 304 m and 422 m, respectively, below the Lexington Limestone (33). These Ordovician units are possible sediment sources. Mississip- pian and Pennsylvanian sands, which would overlie the study area but are eroded, may also be the source of the sand. Further petrographic studies of these alternative sand sources may help resolve this problem. The data concerning the emplacement mechanism of the Clay’s Ferry dike are in- conclusive. The trough-shaped structures in slab 2 from the Clay’s Ferry dike, appear to be bedforms which result from sediment being washed into open fissures; however, they may also represent flow structures produced during downward injection of sediment. The slight ver- tical orientation of elongated grains and the tendency for finer grains to occur in wall inden- tations suggest that the dike sediment was Trans. Kentucky Academy of Science — 47(1-2) emplaced through injection. Although the data are inconclusive, the present investigators pro- pose that the Clay’s Ferry dike was emplaced from above through forceful injection. The dike at Valley View was emplaced along the fault apparently through forceful injec- tion of sediment in a hydroplastic state from either above or below the present exposure level. Evidence for this emplacement mechanism includes: (1) apparent flow struc- tures at the dike exposure and in the slabs prepared from the Valley View dike; (2) vertical aligment of muscovite folia in slabs 2 and 3 and along parting surfaces; (3) vertical alignment of carbonaceous fragments in slab 3; (4) layering parallel to the walls of the dike in slabs two and three; and (5) the tendency for finer grains to concentrate at indentations in the wall rock and the apparent vertical alignment of elongated grains. The Valley View dike also contains evidence for minor fault movement subsequent to its emplacement and cementation. This evidence includes: (1) displaced fractures in slabs 1 and 2; (2) calcite veins that suggest vertical extension in slabs 1 and 2; and (3) a minimum 2.5 cm ver- tical displacement of the dike rock and infilling of limestone breccia in slab 3. Furthermore, the cross-cutting relationships revealed in slab 2 of the Valley View dike (Fig. 8) indicate that nor- mal displacement along south-dipping faults was followed by reverse displacement on north- dipping faults. SUMMARY The sandstone dikes at Clay’s Ferry and Valley View are apparently derived from the same sediment source. The Irvine Formation sands are probably not the sediment source, as suggested by previous investigators (1,2,3). It is, therefore, proposed that sands of Mississippian, Pennsylvanian, or Ordovician age may have been the sand source for the dikes. Structures within the dikes suggest that the Valley View dike was forcibly intruded from above its exposure. We therefore prefer a Mississippian or Pennsylvanian age sand source for the dikes; however, more petrographic analysis is needed. Minor movement on the Kentucky River fault, subsequent to dike emplacement and cementation, is indicated by the presence of faults within the Valley View dike. Cross-cutting relationships of calcite veins and faults reveal that south-dipping normal faults have been subsequently displaced by north-dipping reverse faults.

NOTES MISSISSIPPI RIVER STURGEONS: NEW KEN- TUCKY RECORDS AND COMMENTS ON STATUS. — The three species of sturgeons (Acipenser fulvescens, Scaphirhynchus albus, and S. platoryn- chus) inhabiting the Mississippi River adjacent to Kentucky are among the poorest known members of the state ichthyofauna. Inefficiency of conventional collecting gear and probable historical decline and rarity of some of these species (Kallemeyn, Fisheries 8:3-9,1983; Forbes and Richardson, The Fishes of II- linois, 2nd ed., Nat. Hist. Surv. Div., 1920) has limited the literature on Kentucky populations primarily to anecdotal accounts. Records are usually based on occasional reports by fisheries biologists and sport and commercial fishermen of large individuals (Barnickol and Starrett, Ill. Nat. Hist. Surv. Bull. 25:267-350, 1951; Clay, The Fishes of Kentucky, Ky. Dept. Fish Wildl. Resour., Frankfort, 1975; Burr, Brimleyana 3:53-84, 1980; Cicerello, Trans. Ky. Acad. Sci. 42:132-133, 1981) and on commercial fishery assessments in which the species were not discriminated (Renaker and Carter, Ky. Dept. Fish Wildl. Publ., 1968). Few vouchered collections are known from the state of any sturgeon species (Bailey and Cross, Pap. Mich. Acad. Sci. Arts Lett. 34:169-208, 1954; Burr, loc. cit.; Cicerello, loc. cit.; Clay, loc. cit.), and the paucity of information precludes accurate assessments of disiribution, abun- dance, and conservation status. We report the first vouchered record in Kentucky of S. albus and the first confirmed records of A. fulvescens from the Mississip- pi River of Kentucky. We also comment on the conser- vation status of each species, including S.platoryn- chus, in the Kentucky portion of the Mississippi River as judged from acquisition of specimens, compilation of recent records, and interviews with commercial fishermen. Vouchered records of S. albus were previously unavailable in Kentucky; however, Burr (loc. cit.) regarded it as part of the state ichthyofauna, citing its presence in the Mississippi River, both north and south of Kentucky. On 5 November 1985, we col- lected a 685 mm SL, 1.8 kg female S. albus (SIUC 12549) from the Mississippi River adjacent to Middle Bar (approximately 9 km S of Columbus), Hickman County. The specimen was 1 of 7 sturgeons taken (the others being S. platorynchus) by trotline (10 lines with 40 hooks each, baited with worms and fished over- night). We were previously provided with a head and partial skin of a Scaphirhynchus sp. (SIUC 10563) by Mr. Ronald R. Cicerello taken on 2 August 1984, in the Mississippi River (approximate river mile 921), near Hickman, Fulton County, by Mr. Roy Wiseman, a commercial fisherman. The former specimen con- formed in morphological, meristic, and mor- phometric features to S. albus as presented by Bailey and Cross (loc. cit.); however, the latter specimen possessed features of both S. albus and S. platoryn- chus. The incompleteness of the specimen somewhat precluded our identification, but we regard it as a possible S. albus x S. platorynchus hybrid, a com- bination suspected in other Mississippi River drainage populations (Phelps and Allendorf, Copeia 1983: 696-700, 1983). Assessment of the conservation status of S. albus in Kentucky is problematic given the limited distributional data available; however, discus- sions with commercial fishermen indicate that the species is less commonly taken than S.platorynchus. Deacon et al. (Fisheries 4:29-44, 1979) classified the species as threatened throughout its range. We recommend that the species be placed in the en- dangered category of the Kentucky Academy of Science-Keniucky Nature Preserves Commission En- dangered, Threatened, and Rare Animal list because of its apparent rarity and the lack of information on relative abundance. Twentieth century records of A. fulvescens in the Mississippi River of Kentucky were lacking except for anecdotal accounts from commercial fishermen (Burr, loc. cit.), although Forbes and Richardson (loc. cit.) noted that the species was formerly abundant throughout the Mississippi River. We examined photographs (now at SIUC) of this species caught in the Mississippi River in 1977 above Smith Island Chute, Ballard County, by Mr. Glenn M. Burnett, a sport fisherman, and in 1968 near Columbus, Hickman County, by Mr. Lynn L. Bencini, a commer- cial fisherman. The fish captured by Mr. Bencini was featured in the 8 February 1968 issue of the Carlisle County News. Additionally, Mr. Wiseman indicated he had taken a specimen near Hickman, Fulton Coun- ty, in the late 1960’s (Ronald R. Cicerello, pers. comm.). The former 2 records are the only ones verified for the Mississippi River of Kentucky, and bas- ed on the description provided by Mr. Wiseman, we accept the latter as valid. Branson et al. (Trans. Ky. Acad. Sci. 42:77-89, 1981) listed this species as threatened in Kentucky. As judged from the sporadic occurrence of this species in the Mississippi River and its virtual disappearance from the commercial catch, we consider the population in the Mississippi River as endangered. Only 2 vouchered records (SU 17109, Clinton, Hickman County and UMMZ 111542, Cairo Alex- ander County, Illinois), reported by Bailey and Cross (loc. cit.), were known previously for S. platoryn- chusin the Mississippi River of Kentucky. They also included a verbal report (Barnickol and Siarrett, loc. cit.), on their map of the species range in the Ken- tucky portion of the Mississippi River from Hickman, Fulton County. We have collected or obtained from commercial fishermen 43 specimens of this species from 1979 to 1985, most of which have come from the Mississippi River near Columbus, Hickman County (all SIUC). Interviews with commercial fishermen from Hickman, Columbus, and Cairo indicate the species is taken year-round with greatest numbers oc- curring in late fall to spring. Branson et al. (loc. cit.) listed this species as threatened in Kentucky. Our observations and interviews with commercial 52 Trans. Kentucky Academy of Science — 47(1-2) 53 fishermen suggest the Mississippi River populations of this species do not warrant a conservation status; however, further data on abundance, recruitment, and exploitation rate are needed to formulate management policies to insure that the species con- tinues to provide a commercial fishery. We gratefully acknowledge the cooperation, logistical support, or photographs of specimens pro- vided by Mr. Lynn L. Bencini of Columbus, Mr. Glenn M. Burnett of Barlow, and Mr. Roy Wiseman of Hickman. Mr. Ronald R. Cicerello of the Kentucky Nature Preserves Commission graciously provided a specimen and results of interviews with commercial fishermen. — MELVIN L. WARREN, JR., BROOKS M. BURR, and BERNARD R.

After a motion by Secretary Creek, and a second from the floor, the minutes of the 1984 annual business meeting at Keniucky State University, as recorded in the Transactions Vol. 46(1-2), were approved. Secretary Creek moved that all new members for 1985 be accepted by the Academy. Following a second from the floor, the motion passed. Dr. Creek reported that the 1986 meeting will be a joint meeting with the School Science and Mathematic Association (SSMA), Kentucky Association for Progress in Science (KAPS) and the Kentucky Council of Teachers of Mathematics (KCTM) on November 20-22 at the Radisson Plaza Hotel and Lexington Convention Center. The deadline for submitting papers for this meeting will be May 16, 1986. The sectional of- ficers will be sending out more information in the near future. The secretary states that 50 members had in- dicated they would participate in the proposed speaker’s bureau. He suggested a committee be set up to begin putting together the booklet. It was recommended that the speakers be contacted to determine their continued interest in participating. Dr. Creek indicated the speakers would be contacted. The Treasurers report was made by Dr. Taylor.

The CD remained unchanged until this Fall with the exception of the falling in- terest rates. The Marcia Athey Fund monies were received in the amounts shown above but spread over several months. So CD s were purchased at different times with different investment modes. Since the interest was not used com- pletely, some of it was reinvested as CD s. This is the reason the CD s are not in the amount of the original gifts. However, the money was invested at all times to keep it working. Since the interest rates are not as high as we would like, the monies are being invested in a different mode. Following a motion and a second from the floor, the report was approved. The Audit Committee made the following report on the Botany and Marcia Athey Funds. BOTANY FUND The Botany Fund Endowment has significantly enhanced student research on various aspects of botany in Kentucky. During the eight year period since establishment of the Botany Fund, interest earned from the prin- cipal sum has been accumulated in a separate account. Funds for research grants have been accumulated in a separate account. The principal has grown at an average annual rate of $195.70, while an average of $434.38 in awards have been made annually.

Dendrochronology The recent reinvestment of the Botany Fund principal ($11,529.01) ina GNMA (10.55%) should insure that the current level of funding can be continued. MARCIA ATHEY FUND Growth of this fund has been substantial. Interest earned on these accounts during 1983-85 totaled $17,340.50. Fifty-six% of these earnings was retained while the remainder ($7,624.00) was awarded in five grants. Topics supported by these grants follow: Survey of the Kentucky Lepidoptera. The genus Rubus (Rosaceae) in Kentucky. An undescribed species of rosin weed (Silphium, Asteraceae) in Kentucky. Inner Bluegrass flora. Vascular Flora of Rock Creek Natural Area. Marcia Athey Funds are also being reinvested in GNMA’s with interest accumulation in Money Market Ac- counts. This will provide monthly statements of earned interest and should enhance stewardship of these funds. In summary, the Botany and Marcia Athey funds have positively influenced the study of science in Ken- tucky. This is evidenced by the fact that two of the papers being presented in the Botany Section are the result of research supported by Botany Fund grants. Dr. Winstead reported that there were 17 Educational Affiliates which represented an all-time high. He presented the following list of Educational Affiliates: Sustaining Member University of Kentucky Member Eastern Kentucky University Morehead State University Murray State University Northern Kentucky University University of Louisville Western Kentucky University Associate Member Alice Lloyd College Bellarmine College Berea College Campbellsville College Centre College Georgetown College Kentucky State University Lindsey Wilson College Spalding College Thomas More College 1. COMMITTEE ON PUBLICATION. Dr. Branson made the following report. In several ways, 1985 has been frustrating for the editor, principally because of the printer’s inability to meet publication deadlines, as witnessed by the tardiness of the last two issues. Volume 46(3-4) is still not out, although all materials are in the hands of the printer. Hopefully, this last issue of 1985 will appear while there is still a 1985 in which to appear. Otherwise, the business of publishing the journal has flowed along rather smoothly. Volume 46(1-2) consisted of 80 pages that included 10 feature-length articles, 3 notes, Academy Affairs, the annual program, News and Com- ments, and abstracts of some papers presented at the annual meeting. Volume 46(3-4) — when it appears — will 58 Academy Affairs consist of 75 pages (excluding the index, not yet paginated) that will include 11 features, 3 notes, and Robert Keuhne’s obituary, News and Comments, Academy business, and the index. The cost of printing 46(1-2) was $3,583.72. Although we have not been billed for 46(3-4), it’s length indicates that it will cost approximately the same as 46(1-2), for a total cost for 1985 of approximately $7,200. The subjects of the 21 articles and 7 notes in Vol. 46 were: Zoology and Entomology, 13; Botany and Microbiology, 8; Geology and Geography, 6; Obituaries, 1. Not a bad mix of subject matter, but it would be nice to have a few articles dealing with mathematics, anthropology, chemistry and related fields. Volume 47 is now being compiled, although manuscript flow is on the sluggish side. Unless it picks up tout de suite, 47(1-2) may be on the thin side. but, then, as circles are not known by greainess of size but by the perfectly formed, thus, go publications of this sort. 2. KENTUCKY JUNIOR ACADEMY OF SCIENCE. Mr. Leopold made the following report. Last years operations culminated with the annual symposium held at Eastern Kentucky University. Forty four titles were scheduled of which forty were read. Our other activities included the Lab-Skills Science-Bowl competi- tions and refreshments at the conclusion of our organized activities. The symposium was visited by the K.A.S. Executive Committee which gave us an opportunity to show the “live-side” of K.J.A.S. which is far more animated and interesting than our annual reports. We appreciated the fact that this visitation was the first such “review of the troops” in recent years. Our “Outstanding Science Graduates” program was joined by Cumberland College which made two scholar- ships available. This was in addition to the Ogden Foundation scholarships. Mr. Patrick Stewart of Warren East High School was appointed to serve as Co-Director until the end of the 85-86 school year at which time he will become director of K.J.A.S. This was to provide a smooth transition in the directorate. A serious problem has arisen which makes this year’s outlook very uncertain. Our established symposium day, along with two other possible dates, is being pre-empted by the Kentucky Academic Association. Under ordinary circumstances this would not present an insurmountable problem. But, in this situation we find ourselves pitted against many of the people whose support has been essential for our success. This year we are having to ask our members to make a hard choice of participating in our symposium or in a new State-wide Governor’s Cup competi- tion, operated and governed by the Kentucky Association of School Administration with the active support of the State Board of Education and the Governor’s office. If we actively oppose this new competition we endanger the ad- ministrative support we have enjoyed for years. And if we use our only possible date we stand to lose participation. In conclusion, I would like to take this opportunity to thank the Academy for the help and cooperation it has given me through the years of my tenure as director.

KAS FOUNDATION. Dr. Schwartz reported that many nominations had been received for the Distin- guished Scientist as well as for the Outstanding Teacher awards. He said it was difficult to make the selections because of the many excellent nominees. He thanked Dr. Larry Boucher for the work he contributed in obtaining nominations. Dr. Ralph Thompson presented the following report for the KAS Foundation Botany Fund Committee. During this year (1985) no grant proposals were submitted to the committee for review, thus, no monies were awarded. This assures us that more money will be available during 1986 to fund botanical research in the state. Trans. Kentucky Academy of Science — 47(1-2) 59 The committee is now accepting grant proposals for research to be conducted during 1986. Proposals may be submitted at any time for evaluation. The number of grants awarded depends on the money available in the fund and the amounts requested. Proposals are evaluated on a first-come basis. Not all grant requests are funded, however, all interested students are encouraged to apply. Dr. Joe Winstead presented the following report for the KAS Foundation Marcia Athey Fund Committee. Dr. Winstead said that in 1984 four grants were funded and one was funded in 1985. The proposals that were funded are as follows: 1984 1. Charles Covell, Jr., Univ. of Louisville “Survey of Kentucky Lepidoptera”. $3,350.00. 2. Julian Campbell and Millem Meijer, Univ. of Kentucky “Inner Blue- grass flora”. $1,500.00. 3.

Ralph Thompson, Berea College and Ronald Jones, Eastern Kentucky Univ. “The Vascular Flora of Rock Creek Research Natural Area and Environs, Laurel Co., Kentucky”. $1,374.00. 4. COMMITTEE ON LEGISLATION. Dr. Charles Kupchella presented the following report. Dr. Kupchella said he had been involved in the Kentucky EPSCOR Program as a member of the Planning Committee along with Dr. Hettinger. He is also a member of the Science and Technology Committee of the Kentucky Tomorrow program. This committee has been working on an assessment of science and technology in Kentucky. He presented the following as the final draft of the Committee Assessment. The ability of science and technology to expand human capabilities, improve health and extend life, shrink the world and wage ever more destructive war is well understood, and their impact on the social and economic structure of the world is an established historic fact. Why then are science and technology any more important now than they have been in the past—and why are they of special importance to the citizens of Kentucky at this time? This question has no simpler answer. Because of the accelerating rate at which important breakthroughs in science and technology are currently being created, we find ourselves, along with the nation and every other state, in a new social and economic environment that presents both substantial threats and enormous oppor- tunities. The range of possible futures is greater than it has ever been, and which of these futures Kentucky realizes seems likely to be influenced by: (1) How well the underpinnings and implications of this new era are understood, and (2) How well we plan and act to take advantage of and/or cope with them. Over the past century we have seen developments in science and technology reshape almost every aspect of our lives. While many of us grew up seeing space travel as science fiction, our children now know it as history. Scientific discoveries are being made and applied to all facets of our lives at a staggering pace. The application of microelectronics technology has revolutionized business, industry, agriculture, education and research. The world of true robotics on a grand scale is now within sight. Equally revolutionary developments are happening in many other fields of research and technology. Ad- vances in biochemical research have provided the tools to diagnose and treat many of the most dreaded diseases of humanity, leading to longer, more productive and enjoyable lives. The explosion of our knowledge in this and related areas in the last 20 years has led to the next major phase in new technology— biotechnology and genetic engineering— which will have impact not only on health care but also will revolutionize agriculture, materials and energy production and many other facets of our lives. Indeed, the marriage of biotechnology and microelectronics in the next century will give us the ability to rationally alter the very nature of living organisms on this planet. In its deliberations thus far, the committee has reviewed considerable data and engaged in lengthy discus- sions on the state of affairs relative to technology and scientific research within the Commonwealth. This par- ticular assessment reflects the thinking of the Committee at this point in its deliberations. What we have learned thus far gives us cause for concern and stresses to us the importance of developing a workable, imaginative agenda for Kentucky in this area. The question before us is not whether to choose to participate in the science and technology revolution but whether we choose to sit on the sidelines and watch as the game is played without us. 60 Academy Affairs WHERE HAVE WE BEEN? Throughout its history, Kentucky has lagged far behind most other states in science and technology, unfor- tunately finding itself near or at the bottom of far too many lists. Kentucky has been the home of relatively few corporate headquarters with associated research operations and has never had a federal research installation (such as Oakridge National Laboratory). Rather than encourage university research, the state has been con- tinually distracted by the politics of inter-university competition for resources. Kentucky’s leadership has been dominated by people who have been rather narrowly focused on regional/political interests, oftentimes at the expense of emerging opportunities. Our colleges and universities have suffered from a lack of attention to their research and development activities—activities that are critical to the attraction and development of new in- dustries. Contributing to this lack of attention is a perception shared by many Kentuckians that higher educa- tion in Kentucky is more than adequate. Together these factors have conspired to keep the Commonwealth out of the running, even though a number of our colleges and universities possess some very qualified and highly capable individuals. Throughout the country, Kentucky is perceived as an insignificant player in the science and technology game. A brief review of some of the available data illustrates our historical plight. In the early 1970’s a study funded by the Kentucky Department of Commerce, conducted under the joint auspices of the Kentucky Academy of Science and the Task Force on Public Science and Technology, concluded that Kentucky fared poorly in comparison with the rest of the United States in terms of federal support for research and development activities, with Kentucky ranking 50th among the 50 states in a number of areas. A comparative quality of life study conducted by the Midwest Research Institute in 1973, revealed that Ken- tucky received less than half of the national per capita average per college in federal grants for research and development. Kentuckians received about 13 fellowship and traineeship awards per 100,000 people compared - to a national average of 46. The study also showed that Kentucky employed 77 scientists per 100,000 people versus a national average of 103. In 1978, a study of federal funding of research and development in Kentucky was undertaken by the Council on Higher Education, the legislative Research Commission and the Kentucky Academy of Science. Their findings included the fact that in 1977 Kentucky ranked 8th in a group of 11 benchmark states and next to the last among its contiguous states in total federal obligations for research and development. While it ranked 23rd in population, it ranked 47th in research and development dollars per capita. While ranked 25th in federal tax dollars paid in 1976, it ranked only 40th in federal research and development obligations per tax dollar con- tributed. In more recent years, while perhaps showing some improvement, the basic situation has remained very problematic. Kentucky was identified in 1985 by the National Science Foundation as one of 13 states in need of help in developing its research potential. Again, due to the fact that it finds itself on the low end of the con- tinuum in a number of key areas. What does all of this mean? It means that Kentucky has lacked an historical commitment relative to the development of science and technology and consequently must take aggressive steps to alter the dangerous course on which it now finds itself. WHERE ARE WE NOW? As it enters the new era, Kentucky finds itself in the following situation. Kentucky’s high tech industrial sector is relatively small and is not growing as rapidly as the nation as a whole. Unlike several of the states with similar geographical characteristics, Kentucky does not have an established major center of advanced technology industry development and has not participated significantly in the rapid growth in this sector of the economy. At the same time, Kentucky does have a substantial industrial and related research and development base, both at its universities and in several industries of medium technology industry—notably chemicals, electrical equip- ment (especially household appliances) and motor vehicles. These industries as a group appear to have limited growth potential and also significant long-term potential for substantial technology-induced job losses. There is a significant need for increased research in automation and information technologies to help these companies remain competitive. Most of Kentucky’s small, but important, high technology and medium technology-intensive industries are concentrated in the Louisville and Lexington areas, with, however, significant technology-based industry clusters also at Ashland in Northeastern Kentucky, and at Paducah, Owensboro and Bowling Green in Western Kentucky. Kentucky’s academic science and engineering resources and advanced research are concentrated at the University of Kentucky and the University of Louisville, although educational opportunities at the undergraduate and in some cases the master’s level in scientific and technological fields are available statewide. Research activities at the two research institutions cover a very wide range with certain areas of special focus, including biotechnology, medical sciences (i.e., cancer, aging, pharmaceutical science, cardiovascular re- search), energy-related science and technology and ecology/environment. Trans. Kentucky Academy of Science — 47(1-2) 61 Considering this pattern, and Kentucky equivalent of the “Silicon Valley” seems certain to be centered in Louisville and Lexington, and/or along I-64 between them. There may also be the potential for significant technology-based economic development in the Covington-Newport area, drawing upon the location of the Greater Cincinnati International Airport and the substantial scientific and technological critical mass of the Cin- cinnati Metropolitan Area. A major aspect of the technological revolution is the requirement for strong programs of higher education with emphasis on applied and basic research. The economy of the present and future will depend increasingly on access to such institutions for the ideas and the people absolutely essential for the high technology industries. The University of Kentucky at Lexington and the University of Louisville are our only research universities. Both are in need of increased financial support to develop and maintain the faculties and the research facilities which will make them competitive, first rate institutions! The lack of an aggressive commitment or resources to training and leadership has had a devastating impact on our ability to mount technology-based industry. We rank far below most of our sister states in the region in percen- tages of the population who are engineers, scientists and technicians. Texas, Florida and North Carolina have from three to ten times greater percentages of their population in these trades than Kentucky. We are at the bottom of the list together with Arkansas and Mississippi, both of whom are already making massive efforts at the state level to upgrade their economic and research base in science and technology. Education in the important areas of science and mathematics are critical factors in the development of an ade- quate foundation on which to build effective science and technology initiatives. And yet again, Kentucky lags behind many states in science education. Science is not even considered an essential skill in Kentucky. Perhaps this is one reason why it is often neglected in the elementary grades when student interest is high. Unfortunately, many teachers, because they do not have adequate science training, feel uncomfortable in trying to teach this subject. Not only has science been neglected at the lower grade levels, but many secondary school students have not had adequate training in science. This is particularly troublesome. The public must be sufficiently knowledgeable to be able to apply the tools of technology in their everyday lives and job environments. They must also be able to make informed decisions about the course of change and its implementation, particularly those political decisions which involve the allocation of limited monetary resources. In addition, we must train a sufficiently skilled work force to make the state com- petitive for the increasingly technical industry of the future. Yet by most criteria the products of our primary and secondary education system are woefully lacking in even the basic skills. There is little wonder that the Com- monwealth has been all but bypassed in the recent revitalization of the economy in the South. In addition, Kentucky presently does not possess an adequate supportive environment on which to promote and develop technology-based industries. Certain bureaucratic hurdles at our universities that are regulatory rather than facilatory as well as a lack of the necessary venture capital are two factors that limit the “incubation” of new ideas and enterprises. While some initiatives have been made, there has been little impact. The bottom line is that Kentucky is presently not meeting the challenges created by the demands of the “new economy.” According to one study, employment growth in high technology industries between 1975 and 1982 grew in Alabama 83.5%; Arkansas, 31.1%; Florida, 97.1%; Georgia, 92.3%; Tennessee, 42.9%; Virginia, 30.3%; while in Kentucky it grew at a scant 0.4%. One report made available to Kentucky Tomorrow concluded after reviewing a number of key factors that O Kentucky does not presently have a significantly high technology industry sector, and does not appear to be building one at a time when this sector is growing rapidly nationwide; and O The great majority of Kentucky’s manufacturing industry is of medium to low technological intensity as measured by the number of engineers and scientists per 100 employees generally employed by industries of different types. QUESTIONS AND IMPLICATIONS We are living in an era of rapidly expending technology unlike any ever experienced by humanity. Ninety per- cent of all scientists and engineers who ever existed are alive today. We are indeed in the midst of a scientific “revolution” perhaps unprecedented in our history. The Commonwealth of Kentucky and its citizens must be prepared to meet the challenges created by this “future technocracy” and make the very difficult economic, social and ethical decisions which these changes will surely bring. How well equipped are we in 1985 to make this transition? The answer, we’re afraid, is very poorly. But our future can be one of opportunity. However, the proper base for growth and development is research, both academic and industrial. From an historic point of view, the time is fight for a bold, new initiative. The state of Kentucky is positioned in a fortuitous environmental locale and historic moment. Research in this state could have a major focus in a tripartite program concerned with energy/ecology/environment. Our coal and mining resources are a potential source of greater economic growth and development. 62 Academy Affairs Given the importance of science and technology to Kentucky’s future, we must begin now to develop an ag- gressive, imaginative program in this area. Over the next 25 years, many experts predict that expansion and technology-driven industries will result from “spin-offs” from existing businesses rather than from industrial relocation.

ANNOTATED LIST OF SPECIES This compilation resulted in a list of 76 species, representing 42 genera in 18 families. Taxonomic arrangement, and scientific and common names, are those of Robins et al. (18). Following the scientific and common names for each species, a listing of collection site records is presented with notes on distribution. Use of statements concerning distributional status (i.e. generally distributed, occasional, or sporadic) follow the definitions of Smith (19). Voucher specimens are housed at the institutions or agencies which made collections with the following exceptions. Kentucky Nature Preserves Commission col- lections have been deposited into the SIUC collection. Specimens collected by the Ken- tucky Department Fish and Wildlife Resources are not extant. Lepisosteidae — gars 1. Lepisosteus oculatus (Winchell). Trans. Kentucky Academy of Science — 47(3-4) Spotted gar. Stations 31, 37, 39, 47. Sporadic in mainstream, occasional in lower Clear Creek system. A species of clear pools with vegetation (20), the drainage of suitable habitat has un- doubtedly led to its reduction and cur- rent sporadic distribution. . Lepisosteus osseus (Linnaeus). Longnose gar. Reported by Woolman (4) to be very abundant. There are no recent records. Present in backwater areas of the Smithland Pool (21), it is of probable occurrence in the lower river. . Lepisosteus platostomus Rafinesque. Shortnose gar. Stations 3, 4, 6, 46. Sporadic in mainstream, occasional in Cypress Creek system. Woolman (4) reported this species as being less common than the longnose gar. Amiidae — bowfins . Amia calva Linnaeus. Bowfin. Stations 1, 30-32, 34, 36, 37, 39, 45-47, 49, 50. Confined to the lowlands where it is occasional in mainstream pools, streams, and swamps. Anguillidae — freshwater eels . Anguilla rostrata (Lesueur). American eel. Reported by Woolman (4) to be common. Although there are no recent records, this catadromous species possibly occurs infrequently in the river. Clupeidae — herrings . Alosa chrysochloris (Rafinesque). Skip- jack herring. Stations 48, 56. Sporadic in the mainstream, the only records are from the mid-reach of the river. These records are in need of substan- tiation. Probably ascends lowermost reaches of the river as it is common in the Ohio River (15). . Dorosoma cepedianum (Lesueur). Giz- zard shad. Stations 10, 20, 30, 31, 39, 40, 44, 47-49, 56, 57, 66, 77. Generally distributed in lowland creeks, swamps, and mainstream pools. Hiodontidae — mooneyes . Hiodon alosoides (Rafinesque). Goldeye. Station 30. Recently reported by Pearson (14), it occurs sporadically in the mainstream. Fishes of Tradewater River in Kentucky — Miller and Mills 9. Hiodon tergisus (Lesueur). Mooneye. 10. 11. 12. 13. 14. 15. Station 9. The occurence of this species is based on a record by Axon (12). This record is in need of substan- tiation. The mooneye is occasional in most large and medium-size rivers throughout the state (15). Esocidae — pikes Esox americanus vermiculatus Lesueur. Grass pickerel. Stations 10, 13, 17, 19, 23, 30, 36, 38, 40, 42, 44, 45, 47, 51, 53, 54, 56, 60, 63, 65, 66, 75, 77, 81, 84. Generally distributed in creeks, swamps, and mainstream. Ax- on’s (13) record of E. niger is probably a misidentification of this species. Cyprinidae—carps and minnows Campostoma anomalum (Rafinesque). Central stoneroller. Station 84. Woolman (4) reported the occurrence of this species as rare. There is only a single recent record from the system (Dr. Branley Branson, pers. comm.). An inhabitant of headwater streams, the stoneroller is common in the upper reaches of the physiographically similar Pond, Mud, and Rough river systems (2,6,22). Seasonal desiccation of upland headwater streams and general lack of suitable habitat areas in the Tradewater system have prob- ably contributed to the present rareness of this otherwise widely distributed minnow. Cyprinus carpio Linnaeus. Common carp. Stations 1-6, 8, 10, 12, 18, 20, 27, 31, 32, 36, 37, 39, 40, 45-47, 49, 51, 57, 77, 80. Generally distributed, most records are from lower reaches of the system. Ericymba buccata Cope. Silverjaw min- now. Stations 12, 14, and 17. Sporadic in headwaters of Craborchard Creek system. Hybognathus nuchalis Agassiz. Mississippi silvery minnow. Stations 11, 14, 21, 26. Sporadic, apparently rare in river, though occasional in Craborchard Creek system. Hybopsis amblops (Rafinesque). Bigeye chub. Reported by Woolman (4) to be uncommon. Woolman’s record is con- sidered by Melvin Warren (pers. comm.) to be a misidentification, prob- ably of Hybopsis storeriana. It has 16. 17. 18. 19. 20. 21. 22. 23. 24. 111 not been recently reported. Notemigonus crysoleucas (Mitchell). Golden shiner. Stations 5, 14, 21-23, 25, 40, 42, 44, 48-52, 57-59, 62, 65, 66, 75, 77, 79, 81. Occasional in lowland streams and swamps which have not been channelized or im- pacted by AMD. Notropis atherinoides Rafinesque. Emerald shiner. Stations 2, 6, 8, 13, 14, 18, 21, 49. Generally distributed in lower reach of system. Notropis chrysocephalus (Rafinesque). Striped shiner. Stations 19, 22, 24, 25, 50, 54, 58, 60, 63, 64, 80, 81, 83, 84, 86. Generally distributed in western tributaries and upland reach of mainstream. Notropis emiliae (Hay). Pugnose min- now. Stations 50, 53, 66, 80, 81. Sporadic, though locally abundant. A fish of clear, well-vegetated lakes and sloughs, the pugnose minnow was prob- ably common in the Tradewater system prior to drainage of suitable habitat areas and/or water quality degradation. Smith (23) attributed decimation of this species in southern Illinois to ex- cessive siltation in streams and drainage of lakes and swamps. Notropis fumeus Evermann. Ribbon shiner. Stations 1, 9, 11, 22, 23, 25-28, 45, 49, 51, 53, 54, 56, 57, 61, 65, 66, 78, 81, 83, 84, 86. Generally distributed in mainstream and lower portions of tributaries. Notropis lutrensis (Baird and Girard). Red shiner. Stations 1, 5-7, 11, 12, 14, 16, 49. Generally distributed in lower reaches of system in lowland streams and ditches. Notropis spilopterus (Cope). Spotfin shiner. Station 5. Reported from a single site (SIUC) in upper Cypress Creek. Notropis umbratilus (Girard). Redfin shiner. Stations 5, 12, 14, 16, 17, 22-25, 50, 53, 54, 57, 58, 63, 78, 83, 84. Generally distributed in western tributaries, upper mainstream, and headwaters of Cypress and Crabor- chard creek systems. Woolman (4) stated that this species was quite common. Notropis volucellus (Cope). Mimic shiner. This is probably the species reported by Woolman (4) 112 25. 26. 27. 28. 29. 30. 31. 32. Trans. Kentucky Academy of Science — 47(3-4) as N. deliciosus. Trautman (24) listed N. deliciosus under the current names of N. stramineus, N. volucellus volucellus, and possibly of N. volucellus wickliffi. Notropis stramineus has not been reported from the lower Green River, while N. volucellus wickliffi is abundant in the Ohio and Wabash rivers and is known to ascend tributaries (23,25). Though probable in the lower mainstream, its presence is in need of substantiation. Phenacobius mirabilis (Girard). Sucker- mouth minnow. Stations 11, 12, 14. Oc- casional in channelized portions of Craborchard creek system. Pimephales notatus (Rafinesque). Blunt- nose minnow. Stations 5-7, 11-17, 21, 22, 24, 25, 49, 50, 53-58, 60-63, 66, 77, 78, 81, 82, 84, 86. Generally distributed in western tributaries, upper reaches of mainstream, and headwaters of Cypress and Craborchard Creeks. Sporadic in lowland streams and lower reach of river. Pimephalis vigilax (Baird and Girard). Bullhead minnow. Station 83. Woolman (4) reported this species as abundant. The only recent record is from Sandlick Creek (2,6). Semotilus atromaculatus (Mitchill). Creek chub. Stations 5, 12, 14-17, 23, 24, 29, 53-55, 57, 58, 62, 66, 68, 79, 84. Occasional in headwaters of western tributaries. Catostomidae — suckers Carpiodes carpio (Rafinesque). River carpsucker. Station 1. Only recent col- lection from lowermost section of mainstream (DOW). Woolman (4) col- lected several specimens in the river near Dawson Springs. Carpiodes velifer (Rafinesque). Highfin carpsucker. Station 10. Recently reported by Pearson (14), it occurs sporadically in mainstream. Catostomus commersoni (Lacepede). White sucker. Stations 14, 25, 50, 58, 63, 66, 77, 79, 81, 83. Occasional in upper reach of system in mainstream and upland tributaries. An isolated record exists from headwaters of Craborchard Creek. Erimyzon oblongus (Mitchill). Creek chubsucker. Stations 12, 14, 17, 22, 33. 34. 35. 36. 37. 38. 39. 40. 41. 24, 25, 40, 44, 51, 53, 57-60, 63, 65, 66, 79, 81, 84, 86. Generally distributed in swamps, headwaters of lowland streams in Craborchard Creek system, mid-and upper reaches of mainstream, and western tributaries. Erimyzon sucetta (Lacepede). Lake chubsucker. Stations 42, 44. Sporadic in wetland habitats (2, 6). An inhabitant of well-vegetated backwaters and sloughs (23), it was probably more widespread before drainage of favored habitats. Woolman’s (4) record of this species was a misidentification of the spotted sucker Minytrema melanops (Dr. Brooks Burr, pers. comm.). Hypentelium nigricans (Lesueur). Nor- thern hog sucker. Woolman (4) reported this species as uncommon. It has not been reported recently from the Tradewater River system, nor has it been recently from the lower Green River system (25). In view of an absence of recent records, its presence is ques- tionable and in need of substantiation. Ictiobus bubalus (Rafinesque). Smallmouth buffalo. Stations 10, 18, 45, 46, 31. Occasional in mainstream, sporadic in lower Clear Creek system. Ictiobus cyprinellus (Valenciennes). Bigmouth buffalo. Stations 20, 30-32, 34, 47. Occasional in mainstream and lower Clear Creek system. Minytrema melanops (Rafinesque). Spot- ted sucker. Stations 1, 2, 13, 21, 48, 51, 56, 57, 66, 77, 79-81, 84. Generally distributed in mainstream. Sporadic in tributaries. Moxostoma duquesnei (Lesueur). Black redhorse. Reported to be common by Woolman (4). Melvin Warren (pers. comm.) considers this record a misiden- tification. It has not been reported recently. Moxostoma erythrurum (Rafinesque). Golden redhorse. Stations 1, 13, 25, 58, 77. Sporadic in system. Ictaluridae —bullhead catfishes Ictalurus furcatus (Lesueur). Blue cat- fish. Station 2. Only record of this large river species is from lowermost reach of mainstream (12). This record is in need of substantiation. Ictalurus melas (Rafinesque). Black 42. 43. 44. 45. 46. 47. 48. 49. Fishes of Tradewater River in Kentucky — Miller and Mills bullhead.

Stations 4, 5, 8, 12, 14, 17, 21, 27, 40, 42, 44, 48, 49, 57-60, 65, 66, 83. Occasional in lowland streams, swamps, mainstream, and lower por- tions of western tributaries. Ictalurus punctatus (Rafinesque). Channel catfish. Stations 1-3, 9-11, 18, 20, 21, 31, 45. Generally distributed in lower reach of mainstream; occasional in lower reaches of Cypress, Crabor- chard, Piney and Clear creeks. This species supports a limited commercial fishery in the lower section of the river (Donan Jenkins pers. comm.). Noturus gyrinus (Mitchill). Tadpole madtom. Stations 2, 3, 9, 14, 18, 21-23, 25, 27, 48, 49, 58, 60, 66, 77, 78, 84. Occasional in the mainstream and in lower reaches of tributaries. Noturus miurus Jordan. Brindled mad- tom. Station 3. Rare; a single record reported from Cypress Creek near its mainstream confluence (12). This record is in need of substantiation. Pylodictis olivaris (Rafinesque). Flathead catfish. Stations 2, 3, and 9. Occasional in lowermost portion of system in mainstream and mouth of Cypress Creek. These records are in need of substantiation. Aphredoderidae — pirate perches Aphredoderus sayanus (Gilliams). Pirate perch. Stations 4-6, 11, 15, 17, 18, 21, 22, 24, 25, 27, 28, 38-40, 42, 44, 48, 49, 52, 56-60, 63, 65, 66, 77-79, 83, 84. Generally distributed in mainstream, lowland and upland streams, and in relatively unimpacted portions of swamps in the Clear Creek system. Cyprinodontidae — killfishes Fundulus notatus (Rafinesque). Blackstripe topminnow. Station 5. Col- lected from one headwater site in the Cypress Creek system (SIUC). Fundulus olivaceous (Storer). Blackspotted topminnow. Stations 5, 6, 8, 10-12, 14, 16, 17, 21-23, 25, 27, 31, 38-40, 42, 44, 45, 47-51, 53, 55-59, 61, 63, 65, 66, 68, 78, 79, 82-84, 86. 50. 51. 52. 53. 54. 55. 113 One of the most widespread and com- mon fishes in the system, occurring in a variety of habitats. Woolman (4) reported the occurrence of Zygonectes notatus as rare in the river. It is not certain whether this reference is to the blackspotted or blackstriped topmin- now as, at the time of his collection, these species were synonymous (23). Poecillidae —live bearers Gambusia affinis (Baird and Girard). Mosquitofish. Stations 1, 5, 6, 8, 11, 13-15, 21, 26, 28, 39, 40, 44, 48, 49, 57, 58, 66. Occasional in the mainstream, lowland streams and ditches, and swamps. Atherinidae — silversides Labidesthes sicculus (Cope). Brook silverside. Station 3. Reported from a single site at the mouth of Cypress Creek. Woolman (4) reported its col- lection. Its presence is in need of substantiation. Percichthyidae — temperate basses Morone chrysops (Rafinesque). White bass. Station 1. Known from a single site in the lowermost reach of the mainstream; this species is probably seasonally abundant in spring during spawning runs. Centrarchidae — sunfishes Centrarchus macropterus (Lacepede). Flier. Stations 40, 42, 44-46, 48, 49, 58, 60, 66, 71, 77, 80. Occasional in swamps, lowland streams, and the mainstream. A species of clear, heavily vegetated waters (20), it was probably more widespread and abundant historically prior to drainage and chan- nelization of lowland swamps and streams. AMD has eliminated this species from otherwise suitable habitat in the Clear and Cany creek systems in particular. Elassoma zonatum Jordan. Banded pygmy sunfish. Station 40. Sporadic, the only reported record is that of Warren and Cicerello (6) from the Rose Creek Wetland. Like the flier, this species has experienced a reduction in suitable habitat. Lepomis cyanellus Rafinesque. Green sunfish. Stations 1, 3-6, 8, 11, 12, 114 56. 57. 58. 59. 60. 61. Trans.

Woolman (4) reported both the oc- curence of L. macrochirus and, the now synonymiczed, L. pallidus. Lepomis megalotis (Rafinesque). Longear sunfish. Stations 1-3, 5, 6, 8, 11-15, 17, 18, 21, 23, 25-27, 30, 31, 37, 45-51, 53, 56-58, 60, 61, 63, 65, 66, 77-79, 81, 84, 86. Generally distributed in the mainstream, and in the Cypress, Craborchard, and Flynn Fork systems in particular. Common to abundant at most reported sites. Lepomis microlophus (Gunther). Redear sunfish. Stations 5, 44, 49, 51, 53, 56. Sporadic; present in lowland streams, mainstream, and Land Branch swamp. Pflieger (20) stated that it in- habits waters which are warm and clear, with no noticeable current and an abundance of aquatic plants. Micropterus punctulatus (Rafinesque). Spotted bass. Stations 9, 18, 21, 63. Sporadic in lower mainstream and in lower tributaries near their con- fluences. A single record from upper Flynn Fork system. Woolman’s (4) record of Micropterus dolomieui from the Tradewater River is probably either a misidentification of M. punctulatus or M. salmoides. Hubbs (26) stated that the spotted bass was not generally recognized by fishery workers as a distinct species before 1927. The smallmouth bass has not been reported recently from the Tradewater River, nor has it been taken from the lower Green River system (25). 62. 63. 64. 65. 66. 67. 68. Micropterus salmoides (Lacepede). Largemouth bass. Stations 1, 2, 13, 18, 21, 23, 25, 31, 36-40, 42, 44, 46-49, 51, 56-59, 65, 66, 77, 79-81, 83, 84, 86. Generally distributed in the mainstream and in swamps. Occa- sional in streams. Pomoxis annularis Rafinesque. White crappie. Stations 1, 3, 14, 18, 21, 30, 39, 48-52, 66, 83. Occasional in the lower mainstream, and in swamps. Sporadic in streams. Reported by Woolman (4) as common. The white crappie supports a locally important sport fishery in the lower Tradewater River (William McLemore, pers. comm.). Pomoxis nigromaculatus (Lesueur). Black crappie. Stations 1, 21, 26-28, 31, 37, 39, 40, 42, 44, 48, 49, 58. Oc- casional; most reported collections are from middle reach of system. Percidae — perches Etheostoma asprigene (Forbes). Mud darter. Stations 1, 3, 21, 26, 27, 48, 49, 58. Occasional in lower- and mid- reach of mainstream and near mouths of tributaries. Etheostoma chlorosomum (Hay). Bluntnose darter. Stations 21, 39, 40, 48, 49, 56, 66, 81-83. Occasional; it has been collected in the mainstream, swamps, and streams. Etheostoma gracile (Girard). Slough darter. Stations 11, 17, 21, 22, 26, 39, 40, 42, 48, 49, 51, 56, 58, 59, 63, 66. Occasional in the mainstream, lowland streams, and swamps. Woolman’s (4) reported collection of E. fusiforme has been regarded as a misidentification of this species (27). Etheostoma kennicotti (Putnam). Stripetail darter. Stations 19, 22-25, 39, 40, 42, 48, 49, 55, 58, 63, 64, 66, 78, 79, 81, 82, 84-86. Generally distributed in western tributaries and upper mainstream. Page and Smith (28) stated that abundance of the stripetail darter in southeastern II- linois was related to lack of direct competition with other species of the subgenus Catonotus. The only other member of this subgenus in the system is the distantly related spottail darter, E. squamiceps. Records of E. flabellare by McLemore (10) are 69. 70. 71. 72. 73. 74. 75. 76. Fishes of Tradewater River in Kentucky — Miller and Mills probable misidentifications of the stripetail darter. Etheostoma nigrum. Rafinesque. Johnny darter. Stations 23-25, 49, 54, 58, 60, 64, 81-84, 86. Generally distributed in western tributaries and upper mainstream. Woolman (4) reported this species as common. Etheostoma squamiceps. Jordan. Spot- tail darter. Stations 23-25, 49, 54, 55, 58, 63, 64, 68, 81, 84. Generally distributed in headwaters of western tributaries. Percina maculata (Girard). Blackside darter. Stations 9, 11, 17, 22, 25, 48, 49, 52, 57, 58, 60, 63, 66, 79, 84, 86. Occasional in the mainstream and in lowland and upland streams. Percina phoxocephala (Nelson). Slenderhead darter. Woolman (4) (as Etheostoma phoxocephalum) described its occurence as rare. It has not been taken recently and is considered extirpated. Percina sciera (Swain). Dusky darter. Stations 9, 56, 57, 84. Sporadic in mainstream. Stizostedion canadense (Smith). Sauger. Several specimens of this riverine species were taken in the lowermost reach of the mainstream by students of Dr. James Sickel (pers. comm.). Although this was the first reported collection from the system, it is probably occasional upstream of the river's confluence with the Ohio. This record is in need of substanstantiation. Sciaenidae — drums Aplodinotus grunniens Rafinesque. Freshwater drum. Stations 1-3, 9, 18, 21, 30, 31, 36, 46, 47, 49. Generally distributed in lower mainstream and mouths of lower tributaries. Isolated record from mouth of Donaldson Creek. Cottidae —sculpins Cottus carolinae (Gill). Banded sculpin. Stations 53-55. Sporadic in headwaters of western tributaries. The only records are from the upper Donaldson Creek system. DISCUSSION Although the ecological integrity in por- 115 tions of the Tradewater River system has been severely damaged, much of the ichthyofauna remains. Of the 76 species listed, 62 species are known from recent verifiable collections. An additional ten species (Lepisosteus osseus, Anguilla rostrata, Alosa chrysochloris, Hiodon tergisus, Notropis volucellus, Ictalurus fur- catus, Noturus miurus, Pylodictis olivaris, Labidesthes sicculus, Stizostedion canadense) are of probable, though un- substantiated status. Six records are probable misidentifications (Esox niger, Hybopsis amblops, Moxostoma duquesnei, Micropterus dolomieui, Etheostoma fusiforme, E. flabellare). Presence of Hypentelium nigricans is questionable and in need of substantiation. Percina phoxocephala, not represented in re- cent collections, is considered extirpated. The Tradewater River system presently supports three species (Lepisosteus oculatus, Erimyzon sucetta, Elassoma zonatum) listed by the Ken- tucky Academy of Science and Kentucky Nature Preserves Commission (29) as threatened, of undetermined status, and of special concern, respectively. Ichthyofaunal communities of Clear Creek, Lick Creek, Cany Creek, Buffalo Creek, Hur- ricane Creek, and the Tradewater River mainstream in the vicinity of Dawson Springs, Kentucky, are severely degraded or eliminated by AMD (2,9,10,14) (Figure 1). The future integrity of the Tradewater River ichthyofauna is dependent upon: (1) the iden- tification and protection of ecologically im- portant habitat areas which serve as refugia and reinvasion epicenters, (2) protection of water quality buffer areas, and (3) implemen- tation of effective reclamation practices to improve water quality conditions in streams presently impacted by AMD. Ecologically important habitat areas in the Tradewater River system have been identified by the KNPC (30). Land Branch Wetland, Flynn Fork, Montgomery Creek, Piney Creek, Sandlick Creek, and Rose Creek Wetland are recommended for immediate or potential designation as Outstanding Resource Waters. These systems support ichthyofaunas that are characteristic of relatively undisturbed aquatic habitats in the Western Kentucky Coalfield.

Cause of Reddening in Lettuce — Wall and Elliott A Causative Agent of Reddening in Lettuce Robert W. Wall and L.P. Elliott Department of Biology Western Kentucky University Bowling Green, Kentucky 42101 ABSTRACT Koch's postulates were used in attempts to determine the causative agent of the reddening of lettuce. The results indicate that the predominant causative agents are pseudomanads, particularly Pseudomonas fluorescens. INTRODUCTION Lettuce (Lactuca sativa L.) is high in water content, low in firm tissue, has a high respiratory rate, and is easily bruised, broken, or crushed during harvesting and packing. In- tact surfaces prevent rapid microbial decom- position after harvest, but bacteria proliferate when the plant has suffered mechanical breakage such as a severed stalk. Several diseases occur in the field (14) and marketing process. When head lettuce is cooled by water spray in the retail store, a reddish brown col- or often appears, particularly on the tip. This type of spoilage also develops during storage of lettuce in the home refrigerator. Frazier (5) noted that investigators disagree as to the cause of this spoilage, and Frazier and Westhoff (6) simply called this lettuce disorder a bacterial soft rot. Palmore (12) sug- gested that fluorescing pseudomanads were a cause of this disorder. He found that wrap- ping the lettuce in 100 gauge Saran Wrap and holding it at 9° C proved to be the best preser- vation procedure for the maintaining of let- tuce that is free of the red discoloration under commercial conditions. This work was initiated to further substan- tiate the fact that pseudomonads are involved in the reddening of lettuce. The protocol for establishing the causative agent of a bacterial disease was outlined following Koch's postu- lates (13). Significant numbers of a specific bacterium were continually observed to be associated with the disease in question. The suspected bacterium was isolated, grown in pure culture, and inoculated into a suscepti- ble host. The susceptible host, sterile (bacteria-free) lettuce, was expected to display the symptoms of the disease and the organism re-isolated and identified. MATERIALS AND METHODS Sterilization of the lettuce — Before sterili- Trans. Ky. Acad. Sci. 47:118, 1986. zation was attempted, reddened areas of the store purchased lettuce were excised. Through experimentation with procedures found in the literature, it was found that im- mersing the lettuce in clorox diluted 1:4 with distilled water and agitating the lettuce for 10 min was ample for sterilization (8,9). The let- tuce was rinsed in two sterile distilled water baths for 2 min, each, then placed into a sterile holding container. One cm’ portions of the butt, stalk, and leaf of each head was excised, ground in saline in a sterile mortar and plated on nutrient agar (Difco) which was incubated at 30° C for 48 h. Bacterial Specimens Utilized —The bacteria utilized were 5 cultures isolated by Palmore (12) (designated isolate 2,3,15,16, and 23 in Table 1) as the major flora found in the red- dened portions of market lettuce. These 5 cultures were identified and confirmed by us- ing the API 20E (Analytab Products, Plain- view, NY), oxidase test (Marion Scientific, Kansas City, MO), motility test (hanging-drop preparation),and flagella staining (16). A standard inoculum (4.0 x 107 CFU/ml) from each culture was injected into the butt, stalk, and leaf of three heads of sterile lettuce. The 15 inoculated and control heads of let- tuce were held in containers at refrigeration temperature (5° C) and observed for discolora- tion and sample-plated for bacteria (as previously described) at 3-day intervals dur- ing a 12-day period. Indentification of the predominant flora on the inoculated lettuce was achieved by use of the API 20E system. Controls—Three types of control lettuce were used: heads sterilized and not in- oculated, heads into which a sterile hypoder- mic needle was inserted at sites similar to those where the experimental heads were in- oculated, and heads into which sterile nutrient broth (Difco) was injected at sites similar to those where the experimental heads were inoculated.

By day 6, isolate 3, 15, 16, and 23 (Table 1) caused the lettuce to redden. Isolate number 2 did not cause any reddening until day 9. When these heads of lettuce were sampled the bacteria isolated were identified as the bacteria initially inoculated as illustrated in Table 1. None of the control lettuce reddened or yielded bacteria upon testing, indicating that the sterilization procedure was effective. The data indicate that bacteria, particularly Pseudomonas fluorescens, cause the lettuce to redden. The motile pseudomonads could easily gain entrance into the lettuce plant from the surrounding soil. The sampling for surface pseudomonads might be negative as the pseudomonads could find their way up in- to the plant through the root system. This study emphasized the need to grind the let- tuce and to assay for other than surface pseudomonads. That P. fluorescens acting alone is the only cause of reddening of lettuce is questionable. Perhaps ethylene produced by plant tissues is involved in this defect. Williamson (18) studied ethylene production by diseased and healthy tissues of 12 species of plants. The evolution of ethylene was apparently in response to injury and occurred only as long as the infected tissue was alive. Injury by cer- tain pathogenic fungi was sufficient to induce ethylene production. Penicillium digitatum was found to produce ethylene while growing on potatoe-dextrose agar. The genus Pseudo- monas, as described in Bergey’s Manual (10), is also quite complex, with phenotypic similarities to many other genera. Differentia- tion is made on the basis of rRNA/DNA homology studies which are beyond the reach of many laboratories. Thus, since the pseudomonads are ubiquitous and have metabolic versatility, species other than P flourescens are likely to be isolated from let- tuce. Some of the pseudomonads that have been isolated from lettuce in the past have only been partially characterized and some have been reclassified. For example, P. marginalis, described by Ceponis and Friedman (3) and Billing (2), causes soft rot of lettuce is now assigned to P. fluorescens biovar II. The reddening of lettuce might be associated with the pigmentation of Pseudomonas. Palmore (12) found that his isolates 3, 16, and 23 formed a red pigment on egg-yolk agar. Austin and Goodfellow (1) isolated a gram-negative, nonphototrophic, non-nitrogen-fixing, pink bacterium from the leaf surfaces of Lolium perenne (perennial rye grass) and classified it as a new species, P. mesophilica. Smith and Park (15) noticed that P. putida ATCC 31752 and Pseudomonas sp. ATCC 31753 formed a red pigment in a fermenter under controlled conditions when certain bile acids were used as a sole carbon source. In our study, browning and reddening were noted in the test lettuce. The red and brown were two distinct colors. The red color was Plate 1 (E-3) and the brown was Plate 6 (K-11) as categorized in the “Dictionary of Color” (11). Natural sources, such as fresh marketed let- tuce (120 samples) and fennel (89 samples) 120 were found by Ercolani (4) in Italy to be con- taminated with bacteria indicating fecal con- tamination. In addition, 68.3% of the lettuce and 71.9% of the fennel samples yielded 6 dif- ferent serotypes of Salmonella. Kominoes et al. (9) found high counts of P. aeruginosa in raw vegetables such as tomatoes, radishes, celery, carrots, endive, cabbage, cucumbers, onions and lettuce in hospital kitchens and sug- gested that these foods could act as primary vehicles for introducing the organisms to pa- tients. This study prompted Green et al. (7) to determine whether agricultural soils act as natural reservoirs of P. aeruginosa and to determine whether food plants are commonly colonized by P. aeruginosa from soil in the field. Their results suggested that soil is a reservoir for P. aeruginosa and that this bacterium can colonize plants during favorable conditions of temperature and moisture. Wright et al. (19) studying the flora of foods served to patients in a hospital found Klebsiella, Enterobacter, Serratia and P. aeruginosa in salads which may serve as a reservoir for the above bacteria to colonize and infect susceptible patients. Pseudomonas strains may be the cause of nosocomial infec- tions, particularly in the compromised host where their normal host defenses are depressed (neoplasias, burns, cystic fibrosis, etc.). Certainly pseudomonads are associated with lettuce and further investigations are needed to completely elucidate the factors in- volved in reddening which could be the result of bacterial pigment, enzymes, or enzymes (3) plus some other metabolic product (s) (17).

New Records of the Redside Dace, Clinostomus elongatus (Kirtland) in Kentucky, With Comments About Its Habitat Requirements Les Meade and David L. McNeely Department of Biological and Environmental Sciences Morehead State University Morehead, Kentucky 40351 Lew Kornman and Al Surmont Northeastern Fishery District Kentucky Department of Fish and Wildlife Resources Morehead, Kentucky 40351 ABSTRACT The present distribution of Clinostomus elongatus in Kentucky is based on specimens from Lick Fork in Rowan County and Edward Branch in Menifee County. Recent research indicates that substantial popula- tions occur in headwater tributaries of North Fork of Licking River, Beaver Creek and Red River. In fact, C. elongatus was the dominant species in Slabcamp Creek, Devils Fork and Upper Lick Fork. Streams located in remote, unpolluted hollows may act as refuges for this species in Kentucky. Clinostomus elongatus was found in pools with gravel and sandy substrates; here this minnow was common in cool and clear water, of near neutral pH, in forested watersheds with canopy over the streams. INTRODUCTION Clinostomus elongatus is_ sporadically distributed in the northeastern United States and southern Canada. It has a discontinuous range with several widely disjunct populations from New York to southern Ontario, southeastern Michigan, Wisconsin and southeastern Minnesota. It reaches southward in the Appalachian Mountains to northeastern Kentucky (1,2). Clinostomus elongatus is threatened by habitat alteration and pollution in much of its range (2,3). The present distribution of C. elongatus in Kentucky is based on specimens from 2 localities. This species has been considered to be rare, and possibly extirpated in Ken- tucky (4,5). Clark (6) reported C. elongatus from Lick Fork, a tributary of North Fork of Licking River in Rowan County. Kuehne (7) reported a single specimen from Edward Branch, a tributary of Red River in Menifee County. The purpose of this study was to determine the distribution of C. elongatus in Kentucky and to provide preliminary com- ments about its habitat requirements. MATERIALS AND METHODS Fishes were collected from tributaries of North Fork of Licking River, Beaver Creek, and Red River (Fig.1) by using standard seining and electroshocking techniques. Specimens Trans. Ky. Acad. Sci. 47:121, 1986. were fixed in 10% formalin and stored in 10% formalin or 70% ethanol. Voucher specimens were deposited in fish collections at Morehead State University, Morehead, Ken- tucky and at Southern Illinois University at Carbondale. Thirty five collecting sites were examined from May 1984-April 1986. The selection of collecting sites was primarily based on accessibility by roads and/or trails. The number of specimens collected was recorded for each species so that a rough estimate of species abundance could be determined. Col- lecting sites 1-18 were located in the Licking River Drainage; sites 19-35 were in the Red River Drainage. Collecting sites examined were as follows: 1. Lick Fork, ca. 2.4 km N of Ky. 801, Rowan Co. July, 1985. 2. Wallace Branch of Upper Lick Fork, Rowan Co. 5 July, 1985. 3. Upper Lick Fork at mouth of Wallace Branch, Rowan Co. 5 July, 1985. 4.

Because surface mining has occurred in the past near Redwine, Kentucky (Morgan Co.), water samples were collected at 5 sites in the North Fork of Licking River and 3 sites in Devils Fork for comparison of various chemical characteristics. Additional samples were collected at a site downstream from the confluence of these 2 streams (Fig.1). Four water samples were collected at each site. Two samples were acidifed to a pH of 2.0 or less with HNO, and two were not; all samples were then cooled to 4°C until analyzed in the lab. A Fisher combination pH electrode was used to measure pH in the field. In the lab, non-acidified water samples were analyz- ed for sulfate concentration by the barium chloride turbidimetric method using an HF Instruments Model DRT-100 nephelometer according to standard methods (8.) Acidified samples were analyzed for a series of metals by atomic absorption spectrophotometry. RESULTS AND DISCUSSION Populations of C. elongatus have been found in several tributaries of North Fork of Licking River, Beaver Creek and Red River (Fig.1). Clinostomus elongatus was common in Upper Lick Fork, Slabcamp Creek, Devils Fork, Minor Creek, Yocum Creek and Gladie Creek. In fact, C. elongatus was one of the dominant fish species at most of these sites. Brushy Fork of Beaver Creek and Meyers Fork of Beaver Creek also had substantial numbers of this fish. Clinostomus elongatus was rare at sites 7, 27 and 28; only 1 specimen was found at each locality. Clinostomus elongatus was not found at sites 12-18, 24-26 and 29-35. Species of fish commonly found with C. elongatus included Campostoma anomalum, Phoxinus erythrogaster, Rhinichthys atratulus, Semotilus atromaculatus, Catostomus com- mersoni, Etheostoma caeruleum, Etheostoma nigrum and Cottus bairdi. Notropis chrysoce- phalus was common in the Licking River Redside Dace in Kentucky — Meade, et al. a9 d.

Generally, streams with populations of this species shared certain physiochemical traits; these included cool and clear water, of near neutral pH, in forested watersheds with canopy over the stream. The streamside forest often included hemlock, Tsuga canadensis and white laurel, Rhododendron maximum. Clinostomus elongatus was found in pools with gravel and sandy substrates; current was moderate, and little or no silt was present. Many similar streams in eastern Kentucky oc- cur in isolated hollows and are not readily ac- cessible by roads. This may account for the rarity of this fish in earlier collections. Attempts to relocate the population of C. elongatus reported by Clark (6) were not suc- cessful. Lick Fork is greatly modified from former conditions. It has a mostly unforested watershed used for agriculture, receives seepage from rural septic fields and serves as a source for gravel. Apparently, C. elongatus has been eliminated from this stream. Because this fish needs relatively pristine streams for survival, there is a need to monitor and protect its habitat to insure its survival in Kentucky.

The pH values in this area ranged from 4.50-6.90; sulfate, iron and manganese levels ranged upward to 300 ppm., 1.20 ppm and 1.52 ppm respectively. In Devils Fork, a relatively undisturbed tributary of North Fork of Licking River, C. elongatus was very com- mon. The pH values here ranged from 6.94-7.03; sulfate, iron and manganese levels ranged upward to 14.9 ppm, 0.50 ppm and 0.05 ppm respectively (Table 2). The North Fork of Licking River values are comparable to those for polluted Cumberland Plateau streams; the Devils Fork values are similar to those of unpolluted Cumberland Plateau streams (9,10).

Adult males are dark olive-green on the dorsal surface of their head and body, and bright red on their sides. Adult females are lighter green on their dorsum and have pinkish to pale reddish sides. Schwartz and Norvell (11) used shape and length of genital papillae, length of pec- toral and pelvic fins, body coloration and in- ternal examination of gonads to determine sex. Schwartz and Norvell (11) found that pec- toral fin lengths were always greater in males; they indicated that the ratio of pectoral fin length to head length could be used to deter- mine sex with certainty. In fish 2-4 years old, this ratio ranged from 1.15-1.19 in males and 1.36-1.41 in females. Clay (12) and Trautman (3) indicated that C. elongatus is distinguished from a related species, C. funduloides, by having 60 or more lateral-line scales and a jaw length greater than caudal peduncle depth. Systematic values for number of lateral-line scales, lower jaw length and caudal peduncle depth in C. elongatus agree with comments given by these authors. Systematic values for C. elongatus from Licking River tributaries and Red River tributaries are recorded in Table 3. Table 3. Systematic Data from Kentucky Specimens of Clinostomus elongatus.

Size-Specific Mortality in Gambusia — Hampton Male Preference for Females of Different Sizes in Gambusia affinis: A Response to Size Specific Female Mortality? Raymond E. Hampton Laboratory of Animal Behavior and Behavioral Ecology, Department of Biology, Central Michigan University, Mt. Pleasant, Michigan 48859 ABSTRACT Males of Gambusia affinis from populations in which there are few large females direct most of their courtship time toward smaller females, even though large females produce more offspring than do smaller females. Males from populations which contain relatively larger numbers of large females either do not discriminate among females of different sizes or preferentially court large females. The hypothesis that the potential reproductive success that a male might expect from investing courtship time and energy in a female is apparently determined not only by the fecundity of the female but also by the probability that she will survive at least through the approximately 28-day gestation period is proposed and ten- tatively supported. INTRODUCTION Males of promiscuous species in which males have little or no parental investment are generally expected to be nondiscriminating in their choice of or preference for mates, since male reproductive success is presumed to be not limited by sperm production but by the ability of males to distribute their sperm among available females (1,2,3). However, as Dewsbury (4) has recently pointed out, sperm production and delivery is probably not a trivial cost to males and may in fact limit the number of females that a male can successfully inseminate. When this is the case, and when different patterns of allocating ejaculates or spermatophores to females results in dif- ferences in male fitness, selection should favor those males who exercise some degree of selectivity among available females (4). In promiscuous species, in which female fecun- dity increases with size, males who selectively or preferentially inseminate larger females should sire more offspring, on the average, than males who do not discriminate. While observing courtship behavior of the mosquitofish, Gambusia affinis Baird and Girard, collected in July 1983 from Jap Beaver Lake in south-central Oklahoma and from Hubbard Creek in central Texas (5), I noticed that males from the Jap Beaver population ex- hibited a preference for smaller females while males from the Hubbard Creek population ex- hibited a slight preference for large females. Large females were scarce in the Jap Beaver population and more abundant in the Hubbard Creek population, although the samples col- Trans. Ky. Acad. Sci. 47:126, 1986. lected were too small to permit statistical analysis. The assumption was made that this difference was caused by a higher mortality rate of large females in the Jap Beaver popula- tion than in the Hubbard Creek population. The following working hypothesis was for- mulated: in G. affinis, size-specific mortality of females influences male preference. If larger females have a low probability of surviving the approximately 28-day gestation period, perhaps because of selective predation, males who selectively inseminate smaller females might be more successful, even though smaller females produce fewer offspring. On the other hand, in populations in which large females have a higher probability of surviving, males should not discriminate or should discriminate in favor of large females. In the summers of 1984 and 1985, additional data from several populations of G. affinis were collected to test this hypothesis. Gambusia affinis is widely distributed through- out the southem United States, where its preferred habitats include small streams and densely to moderately vegetated shallow areas in small lakes and ponds. Males grow little after reaching sexual maturity (6) and rarely exceed 3 cm total length, whereas females, which are sexually mature at 2.5 to 3 cm, continue grow- ing throughout their life and may grow to over 6 cm total length. Female fecundity increases with female size (7). Both sexes are pro- miscuous and courtship and mating are almost continuous throughout the warmer months. Females have a gestation period of Size-Specific Mortality in Gambusia — Hampton 127 approximately 28 days, after which they deliver from a few to over 100 well-developed offspring. Females apparently store sperm for extended periods (7), and males virgorously court any female present regardless of her gestational stage. Females are more receptive to males, or perhaps more attractive to males, within a few days after delivering a brood (8). However, even non-receptive females are in- seminated (9). Rapid habituation of males to individual females insures that males do not waste time or ejaculates with any one female but rather allocate a minimal number of ejaculates to many females (5). The primary sex ratio in most poeciilid populations studied is usually skewed in favor of females (7,10,11,12,13,14). This is usually attributed to greater predation on males or greater longevity of females. Recently, however, Britton and Moser (15) found that several species of herons selectively prey on larger female G. affinis in France. In marshy areas where heron predation occurred, the primary sex ratio was skewed in favor of males and the average size of females was smaller than in roadside ditches where heron preda- tion was absent. METHODS Specimens of G. affinis were collected in June and July of 1984 from a small tributary stream of Lake Texoma, Marshall County, Oklahoma; from a shallow bay in Lake Tex- homa at the mouth of Wilson Creek, Love County, Oklahoma; and from Jap Beaver Lake in Jefferson County, Oklahoma. Additional specimens were collected in April of 1985 from Hubbard Creek below Hubbard Creek Dam in Stephens County, Texas; from Quana Parker Lake on the Wichita Mountain Wildlife Refuge in Oklahoma; from the Brazos River approximately 200 meters below Morrison Dam in Palo Pinto County, Texas; and from Jap Beaver Lake. Specimens were collected with dip nets in adequate numbers to permit accurate estimation of primary sex ratios, mean size of both sexes, frequency distribu- tion of various size classes, and female fecun- dity as a function of size. Seining was not an effective method of sampling in the sites studied because of various factors such as underwater brush, emergent vegetation, or the shallow, narrow nature of the creeks. Live specimens from each population were retained for observations of male preference for females of different sizes. Jap Beaver and Quana Parker lakes are both small (ca 20 acres), artificial impoundments with no permanent tributary streams. Both are near the top of their respective watersheds and are thus isolated from other bodies of water from which G. affinis might immigrate. Quana Parker Lake was impounded in the mid-1930’s and Jap Beaver Lake in the mid-1950’s. Since G. affinis is not used as a bait minnow, introduction of G. affinis from other populations into either of these popula- tions is probably rare. Both lakes have areas of shoreline characterized by shallow water with moderate to dense submerged vegeta- tion where G. affinis are found. The Brazos is a major river flowing generally southward from north-central Texas. Morrison Dam is the first of several major dams on the river and was constructed in the 1940’s. Hub- bard Creek flows into the Clear Fork of the Brazos River which, in turn, joins the main branch of the river well above Morrison Dam. The dam, which creates a large reservoir, prob- ably provides an effective barrier to intermix- ing of populations of G. affinis above and below the dam. Current flow and water depth below the dam are variable, depending on the release of water from the reservoir. Lake Texoma is a large artificial impound- ment on the Red River between Texas and Oklahoma. In the summer of 1984, a period of very low water level, those small tributary streams which were not dry supported abun- dant populations of G. affinis. Collections were made from a small stream adjacent to the University of Oklahoma Biological Sta- tion. Since this is an unnamed stream, it will be referred to in this paper as UOBS Creek. Although the water flow in UOBS creek was extremely slow, it was prevented from becom- ing completely dry by periodic discharge of water from large research tanks of the Univer- sity of Oklahoma Biological Station. Hubbard Creek was sampled just below Hubbard Creek Dam where, even during dry periods, there is at least some standing water present. Hubbard Creek and UOBS Creek are in separate watersheds and are therefore well isolated from each other and from any small lakes similar to Jap Beaver and Quana Parker Lakes. Female fecundity as a function of size was determined by dissecting preserved specimens and counting the number of fully developed eggs or embryos (7). A simple linear regression model was used for statistical analysis of the data (16). Male mate preference for females of dif- ferent sizes was determined using males from UOBS Creek, Hubbard Creek, Jap Beaver 128 Trans. Kentucky Academy of Science — 47(3-4) Lake, Quana Parker Lake, and the Brazos River. These populations were chosen because they are well isolated from each other and because they represent 2 distinct popula- tion types with respect to size distribution of females. The Jap Beaver Lake, Quana Parker Lake and Brazos River populations had few large females, while the UOBS Creek and Hubbard Creek populations had relatively more large females. Six males from each population were tested by placing them one at a time into a 57-liter aquarium containing 4 females of different sizes. The total time that each male courted each female in a 20-min observation period was recorded using an OS-3 electronic event recorder (Observational Systems, Inc., Red- mond, Washington, USA). Males were con- sidered to be courting when performing any of the courtship behaviours described by Itz- kowitz (17). Since there was a great deal of variation in the total time that each male spent in court- ship, the time that a male spent courting any one female was expressed as the percentage of the total courtship time by that male. The mean per cent courtship time by the 6 males was determined by the arcsine transformation method (16). The Friedman two-way analysis of variance (18) was used to test for dif- ferences among the mean per cent courtship time directed to each of the four females. Males from UOBS Creek and Jap Beaver Lake were tested in August, 1984, using females from the Clear Fork of the Brazos River. Males from Hubbard Creek and Quana Parker Lake were tested in May 1985, using females from Jap Beaver Lake. Females which were not sympatric with either of the 2 populations from which the test males were collected were used, since there is evidence that males can recognize and prefer females from their own population over females from other populations (19). It is also possible that females might recognize and be more recep- tive to males from their own population, although there is no evidence to support this. Since a female's receptivity to males or her at- tractiveness to males changes with her gesta- tional stage (8), males from the 2 populations which were being compared were tested alter- nately over a period of not more than 2 days. Brazos River males were tested in December, 1985, in a slightly different way. Males were placed in a 38-1 aquarium con- taining 2 large females (45 mm and 46 mm TL) and 2 small females (27 mm and 30 mm TL). Since the Brazos River males were not be- ing tested at the same time as males from other populations, females from the Brazos River population were used. The time spent courting either large female and either small female was recorded as described above. The Wilcoxon test (18) was used to test for dif- ferences between the mean percent courtship time directed to large females and small females. RESULTS Because collections were made at different times of the year in 1984 and 1985, it is not possible to directly compare the size distribu- tions and sex ratios from all of the popula- tions. However, the samples taken within the same year may be compared directly. Since very few immature individuals and no fry were observed in the April, 1985, collections, I assume that these populations consisted only of individuals which had overwintered.

Females in Jap Beaver Lake were significantly smaller than females from UOBS Creek when both were sampled in late July 1984 (Table 1, Fig. 1), and females from both the Brazos River and Quana Parker Lake were significantly smaller than females from Hub- bard Creek when these sites were sampled in April, 1985 (Table 1, Fig. 2). Great egrets and little blue herons were often observed forag- ing in Jap Beaver Lake, Quana Parker Lake, and, at times of low water, the Brazos River. These birds were not observed in either Hub- bard Creek or UOBS Creek, nor was any in- direct evidence of their presence noted. This was probably because of the steep banks and overhead tree canopy of both creeks. Both UOBS Creek and Hubbard Creek support fish species which might prey on adult G. affinis (Lepomis qulosus, L. cyanellus, L. macrochirus, and, in Hubbard Creek only, Lepisosteus oculatus were positively identified). The fecundity of female G. affinis is known to increase with size, but not in a consistent relationship from one habitat to another or from one time of year to another (7).

This preference varies among the populations in a manner that is consistent with the hypothesis stated previously. Whether or not this behavior may be regarded as a male adaptation to size-specific female mortality depends on the validity of two assumptions: that the observed differences in female size distribution and sex ratios in these populations are caused by a higher rate of mortality of large females in some popula- tions than in others, and that the ability of males to inseminate females is not unlimited. Neither of these assumptions is supported by direct evidence obtained in this study, but both are supported by previous investigations or by convincing circumstantial evidence discussed below. The differences in female size distribution among these populations could be caused by differences in food availability or quality, or by differences in selective predation or other causes of differential mortality of large females. The possibility that differences in food availability among the various habitats account for the observed differences may be Trans. Kentucky Academy of Science — 47(3-4) discarded, since such differences would be reflected by corresponding differences in female fecundity (20). On the other hand, there is some evidence to conclude that the differences in female size distribution in these populations resulted from selective predation on large females by herons and egrets in those populations in which there were few large females. Those populations in which there were few large females and in which males were more abundant than females were in habitats in which great egrets, little blue herons, and greenbacked herons were frequently observed foraging, while those populations in which large females were more abundant and in which the number of females equalled or ex- ceeded the number of males in habitats in which these birds were not observed. The female size distributions and sex ratios in these populations were consistent with the data of Britton and Moser (15), who demon- strated that several species of herons and egrets selectively prey on large female G. af- finis in France. The Wilson Creek sample is especially interesting in this regard. The wide, shallow bay formed by the mouth of Wilson Creek at its confluence with Lake Texoma is frequented by foraging great egrets, great blue herons, green backed herons, and little blue herons. In the summer of 1984, when this site was sampled, the G. affinis which would normally be expected in the creek itself were apparently forced into the bay as the creek became dry. Of the 157 mature specimens of G. affinis collected at Wilson Creek, only 6 were females and none of these females exceeded 33 mm (tl). The possibility that the reproductive suc- cess of male G. affinis is limited by their ability to produce sperm or by their ability to deliver sperm to many simultaneously available females has not been tested. However, the assumption that male reproduc- tive success is not limited in these ways in some promiscuous species has recently been challenged on theoretical grounds (4) and there is some empirical support for this challenge. Males of the lemon tetra (Hyphessobrycon pulchripinnis), a pro- miscuous characid, exhibited declining fer- tilization rates with spawning frequency, and recently spawned males were less attractive to females than were males which had not recently spawned (21). In a previous paper (5), I reported that males of G. affinis rapidly habituated to individual females and ex- hibited a declining frequency of copulatory at- tempts with sequentially presented females, Size-Specific Mortality in Gambusia — Hampton 131 which indicates that sperm exhaustion might occur. There are two additional considerations, based on the peculiarities of the mating system of G. affinis, which indicate that male selectivity might be advantageous. Since an individual female G. affinis is likely to be in- seminated by many males, the probability that any one male fertilizes a substantial pro- portion of her eggs might be very small. Thus, males might have to deliver large quantities of sperm to many females in order to achieve a few fertilizations. In this case, it could be to the advantage of males to exercise some degree of selectivity. A second and perhaps more compelling reason to assume that male sperm production or ability to deliver sperm to many simultaneously available females is limited is that males will attempt to in- seminate any mature female regardless of her gestational stage (8,9) and that females that have been previously inseminated still remain attrative to males. In many promiscuous species, a female is no longer available as a potential mate once she has been inseminated and the pool of available females is thus limited. This is not the case in G. affinis. In effect, the pool of available females remains constant and large no matter how many times they have been in- seminated. Since the probability that an in- dividual male could inseminate all of the available females in the population in com- petition with all other males is very small, male selectivity would be advantageous. As Burley (3) pointed out, males of promiscuous species are not expected to be discriminating except when factors such as sperm depletion limit access to simultaneously available mates. Gambusia affinis seems to represent such an exception. In view of these considerations and the observation that males of G. affinis do in fact exhibit selectivity in mate preference, it seems likely that the “sperm is cheap” concept may be overgeneralized and inappropriately applied to some species as suggested by Dewsbury (4). The initial hypothesis, which is at least ten- tatively supported by the data presented here and elsewhere and which is consistent with the prediction of Dewsbury (4), predicts that the potential reproductive success that a male might expect from investing courtship time, energy, or sperm in a female of any particular size is: pS(x) X E(x), where pS(x) is the pro- bability that a female of size X will survive at least the 28-day gestation period and E(x) is the average number of eggs per brood produc- ed by a female of size X. This equation pro- vides only a relative estimate of male success, since it does not take into account the pro- bability that a male actually fertilizes all or a fraction of the eggs of any particular female that he inseminates. The hypothesis thus predicts that there should be an optimum size female in any population which represents the most profitable trade-off between increasing female fecundity and decreasing probability of survival with female size. Whether males of G. affinis or other species with similar mating systems discriminate in favor of large females or small females or do not discriminate should be adequately predicted by this relationship. The hypothesis should be especially useful in investigating possible relationships between predation and male mate preferences in G. affinis and species with similar reproductive strategies.

Nest Box Use by Starlings: Does It Inhibit Bluebird Production? ' Wayne H. Davis School of Biological Sciences University of Kentucky Lexington, Kentucky 40506 William C. McComb Department of Forestry University of Kentucky Lexington, Kentucky 40546 Pierre N. Allaire ” Lees College Jackson, Kentucky 41339 ABSTRACT During a study of bluebird use of different style nest boxes on reclaimed surfaces mines, observations were made of European Starling (Sturnus vulgaris) and Eastern Bluebird (Sialia sialis) productivity. Boxes admitted starlings the first two years of the study; starlings were excluded the third year. Vandalism resulted in 38, 47, and 44 sites available for nesting, respectively, in the 3 years. Starlings used 40% of the sites the first year and 60% the second. Bluebirds fledged 104, 157 and 169 young, respectively. Starlings raised a single brood; bluebirds raised two and three broods. The resource was partitioned temporally; bluebirds nested before and after the starlings, sometimes building over an old nest after starlings had fledged. We found no evidence of starlings evicting bluebirds. INTRODUCTION It has been reported (1) that Eastern Bluebird (Sialia sialis) populations have declined because introduced House Sparrows (Passer domesticus) and European Starlings (Sturnus vulgaris) appropriate most of the nesting sites. The adverse effect of House Sparrows has been well established. House sparrows will evict bluebirds at any stage of the nesting cycle, sometimes even killing adult bluebirds (1, 2, 3). The effect of starlings on bluebird popula- tions remains undocumented. Although Zeleny (1) writes that bluebirds “can never compete successfully with starlings for the use of any cavity that a starling can enter, he presents no evidence to support the state- ment. In our search of the literature we could find almost nothing on starlings evicting bluebirds. During our studies of bluebirds, we gathered data on bluebird productivity when many of the boxes were used by starlings. MATERIALS AND METHODS Two reclaimed surface mines (Press Howard and Two Mile) in Breathitt County, Kentucky, served as the study sites. Both areas were created by mountaintop removal 3-10 years prior to the study. Vegetation on both sites was primariy tall fescue (Festuca arun- dinacea), lespedeza (Lespedeza cuneata), crown-vetch (Coronilla varia), black locust (Robinia pseudoacacia), and autumn olive (Eleagnus angustifolia). Ponds ranging in size from 0.1-1 ha were located at about 400-m intervals. Twenty five nest box stations were established 320 m apart along gravel roads at each site and maintained from 1982 through 1985. All nest boxes had internal dimensions of 13 x 13 x 25 cm. In 1982 we erected 3 boxes at each site: a standard box with a circular entrance 38 mm in diameter; a box with a slot entrance at the top of the front; and one with a slot entrance in the roof (4). Only the slot-entrance boxes ‘ The information reported in this paper (86-8-48) was collected in association with Kentucky Agricultural Experiment Station Project No. 624 and is published with the approval of the Director. ?

Kentucky Academy of Science — 47(3-4) were accessible to starlings. In 1983 at each station we placed 3 boxes with front slot- entrance widths measuring 38 mm, 35 mm, and 31 mm. All were accessible to starlings. In 1985, a single box with a 30 mm front-slot entrance was erected at each site. These boxes excluded starlings but admitted bluebirds. Stations were established 8 April, 24 March and 1 March, 1982, 1983, and 1985, respec- tively. Inspection began one week after place- ment. Each box was inspected every 1 to 2 weeks until boxes were no longer being used for nesting by bluebirds (4 September). Sta- tions were in the same locations each year ex- cept for 6 moved in 1985 due to active min- ing. Nest boxes (3 slot-entrance boxes per sta- tion) were left on site during 1984 but were not monitored. Vandalism resulted in 38, 47, and 44 sites available for nesting in 1982, 1983, and 1985, respectively. RESULTS AND DISCUSSION Boxes received heavy use by bluebirds and starlings. Bluebirds preferred the _ slot- entrance boxes (4) and they fledged 104, 157, and 169 young in 1982, 1983, and 1985, respectively. Starling use of the sites was 40% Tis NESTING 90 120 150 in 1982 and 60% in 1983. Thus, bluebirds suc- cessfully fledged young despite heavy use of boxes by starlings. Egg-to-young success rate was 72%, 67% and 63%, respectively for bluebirds; thus exclusion of starlings in 1985 did not result in an increased success rate of bluebirds. At one station, bluebirds and starlings raised broods at the same time. After the starlings established their nest the bluebirds moved in- to a neighboring box that was not accessible to starlings. This box had previously fledged a brood of bluebirds. With this exception, no more than one box per station was in used at the same time. Thus, if individuals of one species were nesting, the site was generally not available for individuals of the other species. In spite of this, bluebirds fledged nearly as many young in 1983 when more than half the sites were used by starlings as in 1985 when starlings were excluded. Several factors seemed responsible for the apparent minimal effect of starlings on blue- bird production. Bluebirds establish their nests earlier than starlings. Stewart (5) found that the average date of nest-box exploration for bluebirds in North Carolina was 18 March and for starlings 9 April. We found that bluebirds began nesting before starlings (Fig. 1). /)\ « STARLINGS « BLUEBIRDS 180 210 240 JULIAN DATE Figure 1. Eastern Bluebird and European Starling nestlings present during inspection of 47 nest sites on reclaimed surface mines, Breathitt County, Kentucky, 1983. Data for 1982 were similar. Starling and Bluebird Competition in Kentucky — Davis et al. 135 Secondly, starlings always chose empty sta- tions (some sites on both areas were never used); in no case did we find evidence sug- gesting that they evict bluebirds. In one box, starlings nested after bluebirds had fledged. Although there are reports of starlings evict- ing woodpeckers (e.g., 6, 7), we found few records of bluebird evictions, and these in- volved only bluebirds in the earliest stages of nesting. Kalmbach and Gabrielson (6) described starlings taking over a site after bluebirds had started to build a nest, and they reported that among 8 bluebird nests started in their experimental boxes, the bluebirds were driven away from 3 by starlings. They also described incidences where starlings and bluebirds nested “in close proximity” without conflict. Gowaty (2) presented data on evic- tion of bluebirds by House Sparrows. She found that sparrows were more likely to take an empty box than to evict, and that the far- ther into the bluebird nesting cycle eviction was attempted, the less likely it would occur. Apparently eviction is difficult work and is usually avoided if alternatives are available. A third factor was that starlings on our study areas produced a single brood, whereas bluebirds often raised two or more broods. Most boxes were available for the exclusive use of bluebirds by early June (Fig. 1). Thus, there seemed to be temporal partitioning of the resource, rather than competition, with neither species appearing to have a significant negative impact on the other. Although heavy use by starlings had little, if any, effect on the successful production of bluebirds in our nest boxes, this situation may not hold in other circumstances or other areas. In western Kentucky (8), New York (9), Ontario (10), Colorado (11), and Arizona (12) second clutches of starlings were reported in 50 to 92 per cent of boxes from which young starlings had fledged. On our study area, star- lings were rarely seen except during their short nesting season. Perhaps the absence of agriculture or other human activities attrac- tive to starlings rendered the area marginal habitat for this species and unsuitable for later nestings. Perhaps starlings could not tolerate summer heat in these small boxes in open sites. Four broods of starlings near fledg- ing died in the boxes, perhaps because of heat. Clutch size averaged 4.1 (1982) and 4.4 (1983), similar to that reported by others (8, 13) in Kentucky. Egg-to-fledging success was low (43% and 51%), however. We suspect that the commonly accepted view on the adverse effect of starlings on bluebird populations may be exaggerated. The situation may be analogous to what has been found with woodpeckers. Starlings ap- propriate many woodpecker nesting sites and some writers (e.g., 7, 14) have expressed con- cern for the survival of the woodpeckers. Nevertheless, Dennis (15), in a study of the decline of the common flicker (Colaptes auratus) on Nantucket Island during a time when the starling was becoming increasingly abundant, concluded that factors other than appropriation of nest sites were primarily responsible. SUMMARY Bluebirds were nearly as successful at fledg- ing young when 40% and 60% of the stations were used by starlings as when starlings were excluded from the boxes. Bluebirds began nesting earlier and were not evicted by star- lings; the starlings chose empty boxes. Star- lings produced a single brood, whereas bluebirds produced two or more. Bluebirds sometimes built nests over old starling nests and raised broods after the starlings had left. ACKNOWLEDGEMENTS We thank Falcon Coal Company for allow- ing us to work on their lands; S.

NOTES RANGE EXTENSIONS FOR THE MOSQUITO FERN IN KENTUCKY AND TENNESSEE. — Azolla caroliniana Willdenow (Azollaceae) is a small, floating fern found in quiet waters of the Atlantic and Gulf Coastal plains and along the east side of the Mississippi River valley (Lellinger, Ferns and Fern Allies of the United States and Canada, Smithsonian Institution Press, 1985). Common associates are various taxa of Lemnaceae, including Lemna, Spirodela, Wolffia, and Wolffiella. Rapid asexual growth, documented by Shaver (Ferns of Tennessee, George Peabody College, Nashville, 1954), often results in masses that may cover the surface of a pond or pool within a few weeks. However, populations are ephemeral and often ab- sent some years. The presence of reddish pigmen- tation, especially in autumn, is also a noticeable characteristic. Although sometimes locally abundant, documented Kentucky and Tennessee records for Azolla, as resported in recent fern surveys, are scanty and confined to the Mississippian Embayment sec- tion of the Coastal Plain. Eight of the 9 counties with reported populations adjoin the Mississippi River. The purpose of this note is to report the discovery of Azolla in Trigg County, Kentucky and adjacent Stewart County, Tennessee, thus extending the known distribution eastward for about 110 km and onto the Interior Low Plateaus Province in both states. Azolla was not known from Kentucky until 1950 when McCoy (Amer. Fern Journ. 40:211-212, 1950) found a colony in Fulton County near the northern end of Reelfoot Lake. The recent compendium of Kentucky ferns by Cranfill (Ferns and Fern Allies of Kentucky, Nature Preserves Comm., Sci. and Tech. Series 1, 1980) added the three counties directly north of Fulton (Figure 1). Wofford and Evans (Journ. Tenn. Acad. Sci. 54:32-36, 1979), in their atlas of Tennessee plants, showed Azolla from 5 West Tennessee counties. Previous reports from East Tennessee, i.e., by Gat- tinger (Flora of Tennessee, Bureau of Agriculture, Nashville, 1901) from McMinn County and by Ander- son (Univ. Tenn. Ext. Series 6:1-40, 1929; Amer. Fern Journ. 21:64-71, 1931) from Bradley County (based on an 1856 Gattinger collection), could not be con- firmed by Shaver (loc. cit., 1954) in his extensive field and herbarium studies. Likewise, the Shaver report from Davidson County, based on a liquid- preserved specimen at Peabody College (now a part of Vanderbilt University), was not verified by Wof- ford and Evans (loc. cit., 1979) and their distribu- tion map, based on documented records, includes only the Coastal Plain counties indicated in Figure 1. Trans. Ky. Acad. Sci. 47:137, 1986. Figure 1. Documented distribution of Azolla in Kentucky and Tennessee; circles repre- sent previously-cited reports, squares represent new records. During October of 1984 an extensive population of Azolla was found in a swamp covering several ha and resulting from beaver dams on Crooked Creek, a Cumberland River tributary in Trigg County, Ken- tucky. The swamp is within the TVA-managed Land Between the Lakes (LBL). The population was also present in 1985, and examination of several other beaver ponds and wetlands managed for wildlife within LBL also revealed large Azolla colonies in adjacent Stewart County, Tennessee (Figure 1). All collections were from relatively clean pools and were associated with Lemna minor L. No specimens were found in any of the upland ponds or waterholes which are abundant in LBL. Azolla is probably a recent immigrant into the LBL area since the habitat types mentioned (exten- sive beaver ponds, waterfowl management pools) have developed since conversion of the region to public ownership. Cranfill (loc. cit., 1980) related the importance of waterfowl in dispersing this species and the large flocks attracted to LBL by ex- tensive management practices may account for its presence there. Voucher specimens for the new records mapped in Figure 1 are preserved in the herbarium of Austin Peay State University (APSC) with the following data (collection numbers are those of the first author). STEWART COUNTY: Bear Creek Wildlife Management Area, Snake Pond, 85-1052, 8 November 1985; Gray Hollow beaver pond, 85-1051, 8 November 1985. TRIGG COUNTY: Crooked Creek beaver swamp, 84-518, 6 September 1984; 85-988, 11 October 1985. — EDWARD W.

Misc. Publ. 200, 1950; Scoggan, Flora of Canada, Part 2, Natl. Mus. Nat. Sci. Publ. Bot. 7(2), 1978; Soil Conser- vation Service, US.D.A., National List of Scientific Plant Names, Vol. 1, 1982; Staff, L. H. Bailey Hor- torium, Hortus Third, Macmillan Publ. Co, New York, 1976; Sutherland, In Great Plains Flora Association, Flora of the Great Plains, University Press of Kansas, 1986; Weintraub, Grasses In- troduced into the United States, U.S.D.A. Agric. Handb. 58, 1953). This species has now been documented in Kentucky, the collection being ap- parently the first in the eastern United States. Collection data are as follows: KENTUCKY: Bell Co.: Log Mountain Surface Mine Demonstration Area, 18 km W of Middlesboro off Ky. 74 at Maiden Ridge; seasonally wet depression from east highwall seep at Scots pine plantation; locally occasional; associates, Scirpus cyperinus, Carex lurida, C. vulpinoidea, Panicum clandestinum, R. L. Thomp- son and R. A. Straw 85-179; 9 May 1985 (BEREA, KNK, EKY). The Log Mountain site, a 14.2 ha area at 866 m elevation, was contour surface-mined on the Red Springs coal bed in 1963. A grass-legume reclama- tion mix of tall fescue (Festuca arundinacea) and Korean lespedeza (Lespedeza stipulacea) was seeded on the mine bench for initial ground cover in the spring of 1964, and 11 tree species, including Scots pine (Pinus sylvestris), were planted in 1965 toward forestry postmining land use. Also, in 1965, Alopecurus arundinaceus ‘Garrison’ was seeded ex- perimentally in a wet depression adjacent to the east highwall and the Scots pine plantation. In the 21 years since the planting, creeping foxtail has locally persisted, reproduced, and expanded its area of occurrence. At the Log Mountain site, the source of the Kentucky collections, the species appears thoroughly established. 5.0 mm. Figure 1. Alopecurus arundinaceus. Left, spikelet; right, floret, Alopecurus arundinaceus (syn: A. ventricosus Pers.) is distinguished from other U. S. species of its genus by the combination of rhizomatous habit, relatively large spikelets (ca. 5.0 mm long), included awns, somewhat outcurved glume apices, and obliquely truncate lemma tip (Fig. 1). It is most closely similar in general aspect to A. pratensis L., also an introduced European species, which shares the general shape and size of inflorescence and the long-ciliate glume keels. However, A. arundinaceus has included awns, blackish caryopses, and vigorous rhizomes, while A. pratensis has excluded awns, predominantly white caryopses, and weak rhizomes. Creeping foxtail should be searched for in other parts of the eastern United States, especially in wet meadowland environments that have been artifically seeded. — RALPH L.

LIPARIS LOESELII (ORCHIDACEAE) DOCU- MENTED IN KENTUCKY -— Liparis loeselii (L.) L. C. Richard, Loesel’s twayblade or fen orchid, had not previously been recorded for Kentucky (Braun, An annotated Catalog of Spermatophytes of Ken- tucky, J. S. Swift, Co, 1943; Ettman, An Annotated Checklist of the Orchidaeceae of Bell County, Ken- tucky, Annals of Ky. Nat. Hist. 3 1-7, 1976; Fernald, Gray's Manual of Botany, Eighth Edition, Van Nostrand Co., 1950; Gleason and Cronquist, Manual of the Vascular Plants of the Northeastern United States and Adjacent Canada, Van Nostrand Co.,, 1963; Luer, The Native Orchids of the United States and Canada Excluding Florida, New York Botanical Garden, 1975; McFarland, A Catalogue of the Vascular Plants of Kentucky, Castanea 7:77-108, 1942), until its discovery in 1982 in southeastern Kentucky (MacGregor, Two New Orchid Records from Harlan County, Kentucky, Trans. Ky. Acad. Sci. 44 (1-2):90, 1983). This inconspicuous orchid has now been documented from Bell County, the southeastern most Kentucky county within the Cumberland Mountains. Luer (1975) mapped its distributional range from Quebec to Saskatchewan, south to Kansas, Missouri, Illinois, Ohio, West Virginia, North Carolina, and Alabama. The first collection data are: KENTUCKY: Harlan Co.: Pine Mountain Settlement School, near town of Pine Mountain, NNW slope of Pine Mountain at 2200 feet, along upper edge of an old road ina rather dry and weedy situation, Nolansburg Quadrangle. A colony of plants were present in fruit, J. R. MacGregor; 25 July 1982 (EKY). Identification confirmed by C. S. Sheviak. The second site data are as follows: KENTUCKY: Bell Co.: Log Mountain Surface Mine Demonstra- tion Area, 18 km W of Middlesboro off Ky. 74 at Notes 139 Maiden Ridge, 866 m elevation; seasonally wet highwall seep at yellow-poplar plantation; locally occasional; associates, Scirpus cyperinus, Carex in- comperta, Spiranthes cernua, Platanthera lacera, R. L. Thompson, P. S. Thompson, and M. E. Medley 85-1017; 27 May 1985 (BEREA, EKY), and R. L. Thompson and R. A. Straw 85-1600; 27 August 1985 (BEREA). In the eastern United States excluding Florida, there are two species of Liparis: L. loeselii inhabits low wet woodlands, calcareous wet meadows, wet swampy thickets, seeps, and streams, and L. lilifolia, the mauve or lily-leaved twayblade, occurs in dry forest slopes, sandy rocky ledges and ridges, and upland wooded clearings and borders. These two twayblades may be distinguishe:’ by the follow- ing diagnostic key: 1. Flowers yellow-green, lip 4-6 mm long, opaque; pedicels 4-5 mm long; capsules 10-12 mm long; leaves elliptic-lanceolate . . . . L. loeselii. 1. Flowers brown-purple, lip 7-12 mm _ long, translucent; pedicels 6-10 mm long; capsules 14-17 mm long; leaves elliptic-ovate....... L. lilifolia. Observations and field data indicate the rarity in distribution and relative sparsity in numbers of L. loeselii in Kentucky. Since the fen orchid has not been included in the most recent publication (War- ren et al., Endangered, Threatened, and Rare Plants and Animals of Kentucky, Trans. Ky. Acad. Sci. 1986), we believe L. loeselii should merit considera- tion as an endangered species of Kentucky in future addenda. Loesel’s twayblade should be sought in wet sedge-grass meadowlands especially those environments created by disturbances through surface-mining within the Cumberland Mountains. — Ralph L.

NEWS AND COMMENTS KENTUCKY ACADEMY OF SCIENCE CITIZEN SCIENTIST AWARD TO RAYMOND ATHEY The development of science has periodically been enhanced by individuals whose principal profession was far removed from the aspect of scientific in- quiry. In our country a prime example has been Thomas Jefferson and in Kentucky a significant citizen in documenting rare plants of the Com- monwealth was Sadie Price of Warren County. On behalf of the Officers, Board of Directors and Membership of the Kentucky Academy of Science it is indeed an honor and privilege to present this day a special Citizen Scientist Award to Raymond Athey of Paducah, Kentucky, in recognition of his many achievements in the documentation of rare and unusual plants of Kentucky and for his support of botanical and scientific research in the midsouth. Among plant taxonomists of the southeastern United States the name of Raymond Athey is well known for his collection, documentation and dissemination of information concerning the her- baceous flora, particularly grasses, of Kentucky and the surrounding states. Perhaps less well known is his personal support of numerous students in shar- ing his knowledge about Kentucky plants as well his support in developing permanent endowment funds to provide financial support of botanical and scientific research. Since 1979, no fewer than 18 students and faculty of colleges and universities in Kentucky, Indiana, North Carolina and New York have had individual research projects supported financially via the Kentucky Academy of Science from endowment funds developed through the in- terest and efforts of Raymond Athey. From his work as a field botanist, herbaria at Memphis State University, Southern Illinois Univer- sity, Murray State University, Western Kentucky University, University of Louisville and others have received important specimens to add to such reference collections that are of immeasurable value in enhancing our scientific knowledge of plants. Raymond Athey’s contributions to the scientific well being of Kentucky are a permanent legacy. He has, by his leadership and personal example of botanical field work, contributed greatly to enhan- cing the spirit of inquiry in Kentucky. THE MORTON B. RYERSON FELLOWSHIP The MORTON B. RYERSON FELLOWSHIP is established through funds contributed by the Chicago Community Trust. Applications are being solicited for fellowships-in-residence to begin anytime in 1987. Trans. Ky. Acad. Sci. 47:140, 1986 Open to any student, with preference to graduate students, the fellowship awards a monthly stipend of $800, plus room, for any period from two to nine months. Fellows are granted full and private use of a comfortable four-room log cabin with kitchen, spectacularly situated amidst floodplain, hardwood forest on the banks of the DesPlaines River in the Edward L. Ryerson Conservation Area, managed by the Lake County Illinois Forest Preserve District. Fellows will be expected to conduct independent field research on any topic relating to ecology and/or conservation in northern Illinois forests. Cooperation with a local interpretive nature center is encouraged, but the research project is paramount. Applicants should send a two to three page pro- posal, a resume or CV, two letters of recommenda- tion, and a proposed schedule of residency at the Ryerson Conservation Area. Address application or requests for complete fellowship description to: Dr. John W. Fitzpatrick Chairman Morton B. Ryerson Fellowship Committee Department of Zoology Field Museum of Natural History Roosevelt Road at Lake Shore Drive Chicago, IL 60605 Deadline for receipt of 1987 application is 1 February 1987.

VOGEL Range Scientist (retired), USDA Forest Service, Northeastern Forest Experiment Station, Berea, Kentucky 40403 ABSTRACT Tussilago farfara L. (coltsfoot) has become naturalized and occurs on disturbed and waste places in the northeastern United States; consequently, it may have some potential in surface-mine reclamation. Seeding would be more practical and economical than planting rhizomes, but fresh seeds are only viable for about a month, interfering with planting schemes. It was determined that flowers can be uniformly generated by placing mature plants in cold storage for 3 months any time of year to ultimately generate seeds when needed for various revegetation/reclamation planting schemes. INTRODUCTION Tussilago farfara L. (coltsfoot), a member of the compositae and a rhizomatous herba- ceous perennial native of the Old World, has become naturalized on disturbed and waste places in the northeastern United States (3). Coltsfoot’s ecological niche for open, unstable habitats where surface soils are frequently de- ficient in nutrients, aeration, or moisture (4) are subject to the invasion of this pioneering plant where other plants fail to survive. It may be less competitive than agronomic grasses and legumes for light, space, and moisture and might be used as a low-profile companion crop for tree establishment on areas to be reforested. Coltsfoot also aids in soil erosion control. The anatomical and physiological adapta- tions of coltsfoot enhance its pioneering abil- ities on diverse sites. Under very moist soil conditions, coltsfoot survival and growth de- pends primarily on rhizomes for nutrient and water uptake. On the other hand, under very dry soil conditions, adventitious roots may de- velop and penetrate the soil (to more than a meter deep) to obtain nutrients and water (1). When plant population densities become high, photosynthate is directed primarily toward seed production rather than vegetative production resulting in an increase in plant mortality. Coltsfoot will flower and produce seed in early spring, but seeds have a brief viability period and germination is reduced to 50 per cent or 2 TrANs.

This study was initiated to examine the flowering and seed-setting requirements of coltsfoot in order to determine how to maximize propa- gules necessary for applicable planting schemes. MATERIALS AND METHODS Greenhouse and Cold Room. — Four rhizomes', approximately 6 cm long, were planted in each of 4 flats filled with a vermic- ulite-peat mixture (5:1) (V/V) and grown ina greenhouse from November 1983 to Septem- ber 1984 with overhead lights that extended the photoperiod to 18 hours. They were then placed in cold dark storage (4°C, 9 weeks) and subsequently moved back to the greenhouse. Two flats were placed on a greenhouse bench under overhead lighting to extend the photo- period to 18 hours, and the other 2 flats were placed on a bench that was covered and un- covered each day with an opaque plastic sheet to simulate a short-day photoperiod of 8 hours. Additional flats of 10-month-old plants were placed in cold storage for 9, 14, and 16 weeks as a check on the cold requirement. Greenhouse Only.—Four rhizomes were planted in each of 10 flats in February 1984. Flats were placed on a greenhouse bench with overhead lighting that extended the photope- riod to 18 hours. Five of these 10 flats were put on a greenhouse bench in June 1984 with an 8-hour photoperiod by using the plastic sheet procedure. After 8 weeks, these 5 flats were transferred back to long-day conditions by per- manently removing the plastic sheet. The re- maining 5 flats were on an extended 18-hour photoperiod for the entire period. ' Rhizomes for all experiments were denuded of most shoots, flower buds, and roots by gingerly pulling them between two fingers. Growth Chambers.—Thirty-six 64-inch planter pots were filled with a mixture of sand, vermiculite, and peat—5:5:1 (V/V/V). Two coltsfoot rhizomes (6 cm long) were planted in each pot. Groups of 9 pots each were placed in each of 4 growth chambers, each group in a different chamber with a different temper- ature and photoperiod regime. The treatments were: (1) cold x long day, (2) warm x long day, (3) cold x short day, and (4) warm x short day. The long day was an 18-hour pho- toperiod; the short day was an 8-hour photo- period; the cold day was 60°C day, 40°C night and the warm day was 80°C day, 60°C night (Table 1). The growth chambers had standard fluorescent lights with supplemental incandes- cent lights. Two additional growth chambers with 9 pots each were set up under cold temperature with an even-day 12-hour photoperiod (instead of 8 or 18 hours). The first chamber had standard fluorescent lights with supplemental incandes- cent lights. The second chamber had high- pressure sodium vapor lighting, which was on for 4 hours during the middle phase of the day length, with supplemental incandescent light- ing for 12 hours. Because there was little or no growth, the cold-day temperature was raised after 6 weeks from 60°C to 70°C in the cham- ber with high-pressure sodium lighting. RESULTS Greenhouse and Cold Room.—The colts- foot plants in all 4 flats were growing vigor- ously with immature flowers on extended stalks in all 4 trays when put into the cold room. Trays were removed from the cold room and put on the greenhouse bench and after 1 week, new flower buds were extending from below the ground in both long-day and short-day treatments. Of the additional flats placed in the cold room then back to the greenhouse, FLOWERING OF COLTSFOOT IN KentucKy—Melhuish et al. 3 those that were in the cold for 9 weeks did not flower; however, after 1 week, flower buds from above and below the surface appeared in those flats taken out of the cold after 14 and 16 weeks. The apparent discrepancy in the two 9-week treatments may be that 9 weeks is about the minimum cold requirement. Greenhouse Only.—The coltsfoot planted in flats and grown only in the greenhouse grew vigorously during the spring months. During the hot summer months, the plants showed stress, particularly those under the short-day treatment, but plants in all flats resumed their vigor during the fall. After 9 months, flowers appeared on vegetative shoots in all flats re- gardless of day length. During the entire ex- periment, anthocyanin was not usually evident on either short- or long-day plants. Growth Chamber.—After 8 weeks in the growth chamber, one flower stalk in the cold short-day treatment and one flower stalk in the cold long-day treatment had formed from be- low the surface. Anthocyanin was also preva- lent in both cold and warm long-day treated plants. There was some discoloration of the lower leaves of the warm short-day treated plants. After 12 weeks, several flower stalks emerged from below the soil media surface under cold short days; and in 16 weeks, flower buds formed on top of vegetative shoots and flowered in cold long-day treated plants and in warm short-day treated plants. At about 22 weeks, the cold short-day treated plants be- came moribund and went dormant. Flower buds on vegetative shoots formed in about 48 weeks under the warm long-day treatment (Table 1). A few flower buds emerged from below the surface under the cold 12-hour day treatment after about 8 weeks, and leaves developed 3 weeks later. Flower buds sprouted from below the soil surface at about 36 weeks in the cham- ber with high-pressure sodium vapor lighting, but developed on top of vegetative shoots un- der the fluorescent lighting (Table 1). DISCUSSION In the greenhouse and cold room tests, flow- er buds formed in the leaf axils of coltsfoot in late summer and flowered the following spring. A cold temperature of no more than 9 to 14 weeks is apparently the only requirement for breaking bud dormancy. Coltsfoot can also form flower buds on top of vegetative shoots in about 40 weeks when grown in the green- house with an 18-hour-day length. This may be a secondary requirement for flowering to ensure reproduction. In the growth chambers, a few flowers in the cold short-day and 1 flower in the cold long-day treatments emerged from below the soil surface. These flowers may have come from leaf axils not completely broken off the rhi- zome, and dormancy was broken by the cold temperature. The time requirement of 40 weeks for flower buds to develop on top of the vegetative shoots in the greenhouse can be shortened to about 16 weeks by either short days or cold temperatures. The production of anthocyanin in the leaves of only the long-day plants indicated the plant response to photo- period. The plants growing under cold short- day conditions went dormant after about 22 weeks. They started to leaf out after about 33 weeks when the chamber failed. Under the 12-hour-day cold treatment, flow- er buds formed after 36 weeks on top of veg- etative shoots. Since no anthocyanin was pro- duced, the long-day response was probably not stimulated; this may answer why the elapsed time of 36 weeks was similar to that of the response of the greenhouse plants. The establishment of vegetation on drasti- cally disturbed sites such as surface mines is influenced by organic material and soil mix- ture (2). The range of soil types and conse- quently level of soil moisture varies widely from site to site (5). Many of the plants cur- rently used in revegetating disturbed sites are very vigorous but hinder tree growth because of competition for light, water, and nutrients. Coltsfoot is a low profile, intolerant pioneering plant that grows on wet or dry sites, provides erosion control, intercepts rain, has low re- quirements for nutrients, and produces leaf biomass. Investigation of coltsfoot for its po- tential usefulness as a nurse crop may be ben- eficial to reforestation programs on some dras- tically disturbed lands. Coltsfoot seed would be easier and more economical to use than rhizomes in planting schemes. One way of cul- turally producing seed is to grow plants in the greenhouse under long-day conditions for maximum growth and then put the plants in a cold room to be brought out at the appro- priate time. Further studies would now be jus- 4 TRANS. KENTUCKY ACADEMY OF SCIENCE 48(1-2) tified to determine the optimum conditions for producing viable seed from these flowers. LITERATURE CITED 1.

WEBSTER Department of Geography, University of Kentucky, Lexington, Kentucky 40506 ABSTRACT The recent movement of industry to nonmetropolitan America has increased the workforce participation rates for women. As production becomes standardized, companies have located in small towns where cheaper labor supplies are available. Because an unskilled and semi-skilled labor force is more important, availability of female workers is more attractive to employees. However, female workers in rural areas have distinctively different journey-to-work patterns than their metropolitan counterpart. Among a sample of nonmetropolitan industrial workers in Kentucky, no significant difference was found between male and female workers in journey-to-work patterns. More importantly, women workers in female-dominated and low-wage industries had a greater tendency to commute than either males in the same industry groups or workers in male- dominated and high-wage industry groups. The journey to work for women in nonmetropolitan areas is less likely to be a function of income but rather the distribution of job opportunities. INTRODUCTION As a larger percentage of women have en- tered the industrial labor force, there has been a growing interest in the problems that women encounter with respect to their work and home environment and its impact on family rela- tionships. Recent research has been examining the relationship between female job opportu- nities and the journey to work. Most of these studies, however, reflect a strictly metropolitan perspective. It should not be assumed that the activity patterns of female workers in a met- ropolitan setting will directly transfer in a non- metropolitan setting. Clemente and Summer suggest that in general models of metropolitan commuting are not necessarily applicable in nonmetropolitan regions (1, 2). The purpose here is to examine the commuting patterns for female industrial workers in a nonmetropoli- tan region. The results are compared with the patterns for male workers in the same region and findings for metropolitan regions to pro- vide a better understanding of the female jour- ney to work. The expansion of economic activity in non- metropolitan areas since the 1960s is now being well documented. An important facet of rural economic development has been the decen- tralization of manufacturing (3). Although the long term impacts that this phenomenon will have on rural community life are uncertain, numerous researchers are investigating the changes in the rural landscape that may be attributable to increased manufacturing in small towns (4, 5). The growth of nonmetro- politan manufacturing has been credited as a significant factor in the rural population turn- around that has occurred since 1970 (6, 7). By providing more job opportunities in the rural periphery, manufacturing has slowed the rate of out-migration from these areas and non- metropolitan counties are experiencing posi- tive net migration after decades of negative rates. The rural economic revival has also meant more job opportunities for female workers. Several authors have characterized the spatial redistribution of manufacturing as a response to changes in the critical input requirements of a product (8, 9, 10). As every product under- goes its life-cycle and production becomes standardized, the price of labor in metropoli- tan areas may force a company to locate its production facilities in smaller towns where cheaper labor supplies are available. The result has been the establishment of a branch econ- EX METROPOLITAN COUNTIES BARREN RIVER TRANS.

A corollary to the product-cycle model is a greater participation rate by women in the labor force of those industries that have en- tered the mature phase of development. When unskilled and semi-skilled labor become im- portant inputs in the production process, an available female work force is more appealing to employers. These two facets of the evolving nonmet- ropolitan landscape, the increased importance of manufacturing employment and the in- creased participation of females in the work force, suggest that a significant number of women in rural areas are commuting to work. Several metropolitan studies have reported that work patterns for women differ from those of men (11, 12). Women are less likely to com- mute than men and those that do travel shorter distances to work. There is also a higher ten- dency among women to use urban transit sys- tems in their journey to work. The general explanations for these patterns refer to the home responsibilities of women and the fact that monetary cost of commuting would consume a larger proportion of their wages (13). This is especially the case when the woman is a sec- ondary wage earner and has a lower income than that of the primary income earner. It is another matter, though, whether these patterns are relevant for nonmetropolitan communities where most often there are no mass transit systems and the range of local female job opportunities is frequently restrict- Nonmetropolitan portion of area development districts. ed. This study examines this situation by ana- lyzing the journey to work patterns of women among a sample of industrial workers in non- metropolitan Kentucky. Male commuting pat- terns are presented for benchmark compari- sons. Three hypotheses are tested regarding female participation in nonmetropolitan man- ufacturing: (1) that branch plants have signif- icantly increased job opportunities for women; (2) that women do not necessarily commute less than men; and (3) women in low-wage industries do not commute less than women in other industries. MATERIALS AND METHODS The nonmetropolitan portion of the 15 Area Development Districts (ADDs) in the state of Kentucky comprise the region for analysis (Fig. 1). The nonmetropolitan portion is defined as those counties that are not part of a Standard Metropolitan Statistical Areas (SMSA). Not un- like other nonmetropolitan areas across the United States, nonmetropolitan Kentucky has experienced rapid growth in its manufacturing sector over the last 2 decades although the rate of growth has declined dramatically during the 1970s. The percentage increase in manufac- turing employment since 1960 has been sig- nificantly higher in the nonmetropolitan re- gion than for the state as a whole (Table 1). A substantial proportion of this growth in non- metropolitan manufacturing employment has resulted from an increase in branch plant ac- tivity.

Furthermore, increased manufacturing em- ployment has been concurrent with increased female participation in the work force. Be- tween 1960 and 1980, female manufacturing employment increased nearly 112 per cent in nonmetropolitan areas as compared to only 65 per cent for the state as a whole (Table 2). The importance of a female work force to branch plant activity is reflected in the fact that wom- en comprised a significantly higher portion of their labor force; nearly 46 per cent of the branch plant work force in 1980 was female as compared to only 39 per cent of the indigenous firms’ total labor force. This supports the hy- pothesis that the product-cycle of manufac- turing has increased the role of women in the nonmetropolitan work force. To analyze the commuting pattern of these women workers, a questionnaire was mailed to each of the 1,371 manufacturing firms lo- cated in nonmetropolitan Kentucky requesting the county of residence of its male and female employees. A total of 720 firms returned the questionnaire although 6 firms did not differ- TaBLE 2.

This sample was representative of the total population for both branch and indige- nous firms with respect to both firm size and industrial classification (14). The remaining 714 firms produced a sample size of 53,356 workers or 42 per cent of the total number of manu- facturing employees in the region. Males com- prised 57 per cent of the sample while females accounted for 43 per cent, roughly the same percentages as for the region as a whole. RESULTS AND DISCUSSION The journey-to-work patterns of women in this nonmetropolitan setting were aggregated into two groups: 1) those workers who live and work in the same county, and 2) those who commute from a county removed from the place of employment. The journey-to-work patterns for male and female industrial work- ers were not significantly different for the study area as a whole (Table 3). Roughly 27 per cent of all females commuted to a nonmetro firm from another county while just over 29 per cent of the male workers did the same. This indicates that one sex is not necessarily trav- elling farther than the other for work.

This statewide pattern masks a large amount of local variations in the journey to work for both men and women. Historically, the west- ern or non-Appalachian portion of the state has had a more diversified manufacturing base than its eastern, Appalachian counterpart. During the 1960s, the western part of the state experienced a major increase in nonmetropol- itan manufacturing, while the eastern portion grew faster in manufacturing during the 1970s (15). The western portion today has a much higher proportion of the total amount of non- metropolitan manufacturing jobs in Kentucky, while the eastern region is still dominated by mining in many of the counties. The western counties also have a higher percentage of man- ufacturing jobs associated with branch plants while the eastern counties have stronger local firms. Overall, manufacturing opportunities are more frequent in the west than in the eastern part of the state. To analyze commuting patterns at a more local level, the 15 ADDs in Kentucky were used as the basis of observation. The labor sheds for 5 of the 15 districts were the same as the state- wide pattern since the percentages of male and female commuters were not significantly dif- ferent; these districts were Barren River, Blue- grass, Gateway, Kentucky River, and Cum- berland Valley AADs (Table 3). Barren River and Kentucky River also had a significantly lower number of female commuters than the state as a whole while Gateway and Lake Cum- berland had a significantly higher percentage of women commuters than the statewide av- erage. In 6 districts, a significantly higher per- centage of the male industrial workers com- muted from another county than their female counterparts. These 6 districts—Purchase, Green River, Lincoln Trail, KIPDA, Northern Kentucky, and Buffalo Trace—are all situated along the Ohio River. Among these 6 districts, female commuting percentages were signifi- cantly below the state average in the Lincoln Trail and KIPDA districts and significantly above average in the Purchase and Green Riv- er districts. Finally, in 4 of the districts a significantly higher percentage of the female workforce commuted from another county; these were the Pennyrile, Lake Cumberland, FIVCO and Big Sandy. In the Pennyrile and Lake Cum- berland districts, the female percentages were above the state average while in the FIVCO ADD the percentage was below the state fig- ure. Overall, women industrial workers in the eastern districts tended to commute more than their counterparts in the western districts re- flecting in part the lack of job opportunities in FEMALE COMMUTING PATTERNS IN KENTUCKY—Cromley and Webster 9 TaBLe 4.

In this study those industries are lumber (92.6%), tobacco (91.8%), primary metals (89.0%), transportation equipment (84.7%), chemicals (83.5%), petroleum refining (81.8%), stone, clay, and glass (76.1%), food (73.2%), fur- niture (70.8%), and nonelectrical machinery (70.6%) the eastern counties. Those areas in the east that did not have higher than expected levels of female commuting were dominated more by indigenous firms and mining operations. An earlier study found that workers tended to commute less among indigenous manufactur- ing firms than they did among branch plants (14). Finally, male/female differences also seem to be a function of the distribution of manu- facturing jobs. The industries of the districts located along the Ohio River are more male oriented as many metalurgicai and chemical companies have been attracted to this area. To examine this relationship fully it is necessary to examine commuting patterns among various industry types. As previously discussed, several explanations are given for the shorter work trip of women in a metropolitan setting. The most common are (1) women tend to choose jobs closer to their residences because they value their com- muting time differently than men; (2) they have less accessibility to private transportation; (3) their job provides secondary rather than primary income for a family; and, (4) they tend to work in low-wage industries thereby reducing the net-monetary benefit of employ- ment if long distance commuting is necessary. Due to the constraints of the data set, the first 3 explanations cannot be examined here al- though some form of private transportation is the only option in most nonmetropolitan areas. If the fourth explanation holds true for women in a nonmetropolitan setting, then women in low-wage industries should commute less than Low-wage industries?

In the last section, it was mentioned that more men commute from another county than wom- en in those districts along the Ohio River be- cause many male-dominated industries were located there. It is expected that women in a female dominated industry group will com- mute less than men and women in the male- dominated industry group. A female-domi- nated industry is defined here as one in which 70 per cent or more of its workers are women; likewise, a male-dominated industry is one in which men comprise at least 70 per cent of its work force. As expected, there is a significant difference among women in a female-dominated indus- try and male-dominated industries (Table 4); however, women in the female-dominated in- dustry group not only show a greater tendency to commute than males, they also show a great- er tendency to commute than their female counterparts in the male-dominated industries (Table 5). With respect to wage levels, women in the low-wage industry group once again not only had a greater tendency to commute than males in similar industries, they also show a greater tendency to commute than females in the high- wage industries. In this nonmetropolitan area, commuting patterns for women are contrary to expected results although the men follow the metropolitan pattern. Again, the avail- ability of jobs is probably more of a factor in nonmetropolitan regions. Firms moving into nonmetro areas are seeking sites that have available pools of unskilled labor. The lack of competition from other firms in the area means 10 TRANS. KENTUCKY ACADEMY OF SCIENCE 48(1-2) that the female workers of these low-wage in- dustries must travel longer distances in their journey to work. SUMMARY It is clear that the nonmetropolitan indus- trialization phenomenon has had a major im- pact on the social and economic life of non- metropolitan America. One aspect that has not received attention in the literature has been nonmetro industrialization’s impact on female participation in the industrial work force. This paper has shown that the filtering of industry to rural areas has increased the job opportu- nities for women in nonmetropolitan areas. However, unlike women in metropolitan areas, these nonmetropolitan workers have distinc- tive journey-to-work patterns. The results of this study imply that the dif- ferentials in the commuting patterns of male and female industrial workers in a nonmet- ropolitan study are not the same as those in recent metropolitan investigations. As shown here, females are not restricted to shorter work trips among nonmetropolitan industrial work- ers in Kentucky and there is no significant dif- ference in the journey-to-work patterns of males and females. Although hidden in the aggregate sample, important regional and industrial vari- ations were identified. Women were more like- ly to commute in the less industrialized eastern regions of the state reflecting in part the lack of closer intervening opportunities in these areas. However, the most significant finding indicates that females in female-dominated and low-wage industries have a greater tendency to commute than males in those same industry groups and other females in male-dominated and high-wage industry groups. Although this study has shown that non- metropolitan commuting patterns among fe- male are significantly different from metro- politan patterns, it does not fully explain why or how women are making the journey to work. More research is needed regarding the signif- icance of women’s contribution to total,family income and their relationship to the head of household. Is a woman’s income more critical in nonmetro areas than in a nonmetropolitan setting? Secondly, how are women getting to work in a rural setting where private vehicles are the only mode of transportation? As the role of women in the work force continues to increase it is essential that we have a better understanding of their problems and patterns.

Most species are illustrated. Some species from peripheral areas are included. INTRODUCTION In various environmental impact statements and many biological surveys of Kentucky waters, one group of organisms is practically always covered in a very cursory manner or omitted altogether. The aquatic snails form one of the most conspicuous and diverse groups of benthic organisms in the state. The most apparent reason for this hiatus in knowledge is the lack of easily available literature on the gastropod fauna, particularly the lack of iden- tification guides. Other than the two checklists (1, 2), most of the literature is quite old and widely scattered. The purpose of this contribution is to pro- vide a set of keys designed specifically for the identification of the species of aquatic gastro- pods known to live in Kentucky (some of the keys include species which should be here but which have not been reported) and to sum- marize briefly the taxonomic changes that have been published during the last several years. Taylor (3) excluded the genus Antroselates and its only known species, A. spiralis, de- scribed by Hubricht (4) from Kentucky cave waters, from the family Hydrobiidae, sug- gesting that the snail was probably an Amer- ican representative of the family Micro- melaniidae. Somatogyrus integer (Say) is syn- onymous with S. subglobous (Say) (5). The specimens reported from Kentucky as Lioplax sulcosa Menke are L. subcarinata occidentalis Pilsbry. Some additional important taxonomic find- ings include the following. Hubendick (6) combined the families Ancylidae and Planor- bidae, erected the new familial designation Ancyloplanorbidae, and fused several genera. Planorbula now includes Menetus and Pro- menetus, and the genus Gyraulus includes Ar- miger. This arrangement is followed here, al- though Burch (7) retained Menetus and ll Promenetus as separate genera. Finally, most American gastropod experts continue to sep- arate the Pleuroceridae from the principally Asian Thiaridae, even though the two groups are virtually indistinguishable, as pointed out many years ago by Wenz (8) and Hyman (9). If this logic is followed, the name Thiaridae would have priority. However, to avoid con- fusion this author follows Burch (7) in retaining the very familiar name Pleuroceridae.

JAIsINGH Department of Mathematical Sciences, Morehead State University, Morehead, Kentucky 40351 WILLIAM J. KOLARIK Department of Industrial Engineering, Texas Tech University, Lubbock, Texas 79409 AND Dipak K. Dey Department of Statistics, University of Connecticut, Storrs, Connecticut 06268 ABSTRACT This research effort has developed a mathematical model for bathtub-shaped hazards (failure rates) for operating systems with uncensored data. The model can be used to predict the reliability of systems with bathtub hazards. A warranty application is demonstrated. The model developed for the general bathtub pattern of failure takes into account all 3 failure regions (increasing, decreasing, and constant) simultaneously and is validated by least squares estimators. Also, the Kolmogorov-Smirnov (K-S) goodness-of-fit test is applied as an aid in selecting the best representation for the reliability function. INTRODUCTION Reliability modeling is an important tool in the design and evaluation of a system since it helps to enable one to understand the success- failure behavior of systems. One way of de- termining the model is to plot the failure data and evaluate it. Researchers, having plotted and examined failure data for several years, began to recognize several general models of failure; namely, increasing, decreasing, ran- dom and bathtub failures or hazard patterns. The curve of Figure 1 has been discussed by early researchers on the subject of reliability (1) and is often called the BATHTUB CURVE because of its shape. A decreasing failure rate is usually encountered during the early life of a system, when failures are primarily due to initial weaknesses or manufacturing defects. This period is called the “infant mortality” period. A second type of failure occurs when the system fails by chance alone and the failure rate is nearly constant. This type of failure is generally observed when the environmental stresses exceed the design strength of the sys- tem. It is difficult to predict the environmental 20 stress amplitudes or the system strengths as deterministic functions of time, thus these chance failures are often called “random fail- ures.” A third type of failure is characterized by an increasing failure rate as operating hours are accumulated and the system ages and de- teriorates. This region of failure is called the “wearout” period. Graphing these failure rates simultaneously will result in a bathtub-shaped curve. Most investigators in the past have not considered the 3 phases of failure of the bath- tub curve simultaneously. This investigation is concerned with the construction of a contin- uous hazard function that incorporates all 3 modes of failure simultaneously, the investi- gation of some of its properties and a warranty application. In order to understand the state-of-the-art in bathtub hazard functions, a brief review and some basic definitions of terminology used are in order. Definition 1: Reliability— is the probability of the system not failing by time t and is defined as RELIABILITY MODELING— Jaisingh et al. 21 We f(z) dz where f(z) is the probability density of failure as a function of time. Definition 2: Hazard Rate—is the conditional probability of fail- ure, given that the system has not failed by time t and is given as From this it follows that f(t) = h(t)- R(t). Hjorth (2) considered a survival probability or reliability function _ exp(—at?/2) R(t) (+ Bye” where a, 8, 6 > 0 with the corresponding haz- ard rate h(t) = at + ; => 0 2 1+ Bt 2] When 0 < a@ < 68 in [2], the curve is bathtub. An equivalent form of equation [2] was given by Lawless (3) as r NO Sea ae t=0 [3] where X, ¢ > 0. Gaver and Acar (4) presented some general procedures for constructing bathtub hazards and a 4-parameter example given by them was of the form +Bt+D, t2=0 [4] aw) tasG where A, B, C, and D > 0 and B < A/C?. Another model for the simultaneous contin- uous bathtub hazard function was given by Shooman (1). The method for deriving the model is not an exact one but an approximate method for describing the hazard function for a given bathtub curve. This method is often referred to as a piecewise-linear analysis meth- od. The accuracy of the method increases as the number of fitted segments increases. l ——_+}— Random failures Wearout failures h(t) Early failures ' ! ( ! I | i) Time Fic. 1. General bathtub curve. Considering Figure 2, the 3 regions chosen are i= tt = t,t, — t = t,and t, 0 is a decreasing function of t such that lim g(t) > 0; k(t) is an increasing t-0o function of t such that k(0)=0 and lim t-0o k(t) + 00, and X > 0 is a real number. Such a function can yield a bathtub curve that satisfies the properties of a hazard function. Therefore, let s)= o>0 06> 0, t=0 [11] and k(t)=at, p=1, a>0, t2=0. [12] The proposed model is then h(t) =A + pipire +at’, t=O. [13] t+¢ This model simultaneously describes the bath- tub hazard function when the parameters sat- isfy their restrictions and is indeed a flexible hazard function that can fit various bathtub patterns.

VALIDATION AND WARRANTY APPLICATION OF THE MODEL The model was validated by using the in- formation given in Table 1 (6). Table 1 gives the generated reliability, hazard rate and den- sity values for ninety components over a period of 10,200 hours at 600-hour intervals. These values were obtained by Kececioglue (6) by grouping the failed components into two sub- populations. The six-parameter mixed Weibull _3T ae T eee 650 90 650 a 532.27 Rees ‘ (5) [22] 90 5,750\5,750) © generated the density values and R(t) - 1 es) + 58 (or) [23] generated the reliability values.

Plot of P(X; > w) against burn-in times. f(t) = h(t)-R(t). For illustration purposes the derived model will be demonstrated using these generated values as the observed values. The estimated least squares parameter values for the hazard function were \ = 9.946898 x 10-6, 6 = 2222.97288 x 10-4 or = 220, a= 7.696699 x 10°! and p = 149. 44079 x 10° with an R? (hazard) value of approximately 98% using SAS PROC NLIN. Figure 3 shows plots of the observed and predicted values for the hazard rate. In addition, Table 2 gives the predicted hazard and reliability values and the absolute differences (| observed-predicted | ) for the reliability values. Using the K-S goodness- of-fit test, D,,,, (reliability) = 0.00769 < D, = 0.3180 at the 5% level of significance. There- fore, the fitted reliability model does provide acceptable results in predicting the reliability values. Example: Given a warranty period, determine the optimal burn-in time for a system with the simultaneous bathtub hazard rate such that the system does not fail before the war- ranty period expires. RELIABILITY MODELING— Jaisingh et al. 25 Solution (values of A, 0, ¢, & and determined above are used to work this example): Let X be the random variable for the life of the system from time zero. Let X; be the ran- dom variable for the life of the system after burn-in of time T. Let w be the warranty period. Theoretically, one needs to compute B(xe' = w)! Now, P(X; > w) = P(X — T>w|X > T) = 10.C SP Se aie |p Se dD) Pox Tt wx 1) P(X > T) eR (SS sw) P(X > T) R(T + w) 7 ay ed where R is the reliability of the system from time zero. Then by using equation [15], P(X; > w) = ex] —Aw — 6|n(1 + w/(T + 4)) Qa - (T+ wet? pt+l te = 7] [25] Observe from Figure 4 that the plot of P(X; > w) against burn-in times results in curves that are concave downwards. This is a direct result of the bathtub nature of the proposed hazard model. The optimal burn-in time will corre- spond to the time when P(X; > w) is a max- imum. For w = 30, 60, and 90 days, the optimal burn-in times were 1,800, 1,400, and 1,000 hours, respectively. The corresponding prob- abilities that the system will survive beyond these warranty periods for these burn-in times were 0.88026, 0.77041 and 0.66752, respec- tively. CONCLUSION The purpose of this paper has been to con- struct a (flexible) bathtub hazard model for nonrepairable systems with uncensored data. Special cases of the model produced classical density functions that frequently arise in re- liability studies. The validity of the model was established by the nonlinear least-squares es- timation method. Potential applications of the model include the effect of burn-in to elimi- nate the infant mortality region so that the finished product will be operating in the region of near constant failure rate, and situations where one desires to model the entire lifetime of a product or population; where the lifetime is characterized by a period with a decreasing failure rate, a constant failure rate and an in- creasing failure rate. The example presented illustrates how the optimal burn-in time can be computed for different warranty periods. LITERATURE CITED 1. Shooman, M. L. 1968.

Voucher specimens are in the herbarium of Northern Ken- tucky University (KNK). Linum grandiflorum Desf. Small population on a steep roadside slope N of the I-275 bridge, Ft. Thomas, Camp- bell Co., 15 Jun 1986, JWT & JOL 56402. This North African species is not included in the key to Linum in Gray’s Manual of Botany (8th ed., American Book Co., New York, 1950) but is mentioned incidentally in the text. Among North American flaxes it is unmistakable because of its large (3-4 cm wide) flowers, its deep red petals, and its long (8-11 mm long) sepals. We suspect it was probably introduced to this site in seed sown for purposes of reveg- etation. The hillside was severely disturbed during high- way construction about 7 years ago and is now highly eroded. Papaver dubium L. Rare in railroad yard 2 miles S of Latonia, Kenton Co., 8 May 1985, JWT 56066; same lo- cality, 2 Jun 1985, JWT 56069 (in fruit); locally abundant along railroad tracks, 3.2 km SE of Ross, Campbell Co., 20 May 1986, JWT 56350. These plants have red-orange 26 petals, dark brown anthers, and rather narrowly obovoid to obconic, glabrous capsules with 7-9 stigmatic rays. Their striking petal color makes them easy to see in their rather drab habitat. Although P. dubium, a European species, is said to be “very variable” (Mowat and Walters in Flora Europaea 1:248, 1964), our plants are quite uniform in basic vegetative and floral morphology, even though they vary considerably in stature. The capsules match well the one shown in Gleason (The New Britton and Brown II- lustrated Flora of the Northeastern United States and Ad- jacent Canada, New York Botanical Garden, New York, 1952). Salvia pratensis L. Hundreds of plants on steep, open slope and eroding cutbank above Hands Road, 1.6 km S of junction of Hands Road and state route 17, Covington, Kenton Co., 4 May 1986, JWT 56329. With the leaves chiefly in a basal rosette (only 2-3 pairs of leaves on the stem); the nearly sessile flowers; the purple corollas with a strongly curved upper lip; and the 3-toothed upper calyx lip, this handsome European species is easily identified. — James O.

Sci., 48(1-2), 1987, 27-32 ACADEMY AFFAIRS THE SEVENTY-SECOND ANNUAL BUSINESS MEETING OF THE KENTUCKY ACADEMY OF SCIENCE Lexington Convention Center Ballroom 1 Lexington, Kentucky 20-22 November 1986 MINUTES OF THE ANNUAL MEETING The meeting was called to order by President Covell at 0915, 22 November, in Ballroom 1 of the Lexington Con- vention Center. There were approximately 75 members in attendance. The Secretary's report was made by Dr. Creek. The approval of the minutes of the 1985 annual meeting was deferred until the 1987 annual meeting since they were recorded in Vol. 47(1-2) of the Transactions which has not been published. Dr. Creek moved that all new mem- bers for 1986 be approved. Following a second from the floor, the motion passed. The Treasurer’s report was made by Dr. Taylor.

The reprinted volume of the Transactions Vol. 46(3- 4) will be reissued within a few weeks. According to the University of Kentucky Printing Office, Vol. 47(1-2 & 3- 4) will be published in early 1987. Dr. Branson announced that the Executive Committee had decided to return to Allen Press for publication of the Transactions starting with Vol. 48(1-2). This will put the publication of the Transactions back on schedule. 2. KENTUCKY JUNIOR ACADEMY OF SCIENCE. Mr. Pat Stewart made the report. Last year’s operations culminated with the annual sym- posium held at Warren East High School. Forty-four titles were scheduled of which 39 were read. Our other activities 28 TRANS. KENTUCKY ACADEMY OF SCIENCE 48(1-2) included a tour of the General Motor Corvette plant, Lab- skills, Science-Bow] Competitions and refreshments at the conclusion of our organized activities. The symposium was once again honored to have as special guests the K.A.S. Executive Committee. This gave us an opportunity to show our “troops in action.” We appreciate the fact that this was the second year for review by the K.A.S. Executive Committee. We hope this will become an annual part of the K.J.A.S. symposium. Scholarships were once again offered by Cumberland College and Western Kentucky University in conjunction with our “Outstanding Science Graduates” program. This year promises to be another exciting year for K.J.A.S. The data base has been established and we now have the capability to send personalized letters to our clubs. Of the clubs that have joined, enrollment for each club seems to be up. Our annual symposium is scheduled at Eastern Kentucky University on 24-25 April 1987. 3. MEMBERSHIP COMMITTEE. The report was made by Dr. Dahlman. A total of 43 individuals at 33 different colleges, uni- versities and state agencies were contacted to serve as KAS representatives at their respective work places. Each was provided with KAS application blanks, brochures, etc. A list of those individuals is attached and appreciation is expressed to each for their willingness to serve. At the winter meeting of the KAS Board, approval was given to change the name and definition of the Industrial Affiliate to that of Corporate Affiliate. Having this ap- proved change in hand and through the assistance of Mrs. Jane Dennis, Kentucky Department of Economic Devel- opment, we were able to obtain mailing addresses of a large number of Kentucky businesses with science inter- ests. Throughout the summer and early fall a strategy was developed to present these companies with the opportunity to support KAS as Corporate Affiliates and to give KAS an opportunity to interact and serve these same companies. The final product consisting of letters from President Charles Covell on KAS letterhead, a revised brochure describing KAS and an invoice were sent to approximately 250 com- panies within the state. As a part of the above described activity, the brochure describing KAS was edited, updated and reprinted. These were placed in each registration packet to be picked up by those attending the combined SSMA-KAS meeting in Lexington. They will also be used for future membership promotion activities. The committee strongly endorses the establishment of a collegiate level KAS program. A separate committee is working on plans for this program. During this past year, all individuals who have not paid dues since 1983 were removed from the membership list. The total number of members as of 16 November 1986, that have paid dues at least in 1984 is 782. Of this number, 524 have paid their 1986 dues (including 49 life members). Of the remaining 258, many have paid their 1985 BUT NOT 1986 dues. The net increase of 11 members over 1985 resulted after purging those who had not paid dues since 1983. We have actually had 91 new members added to the roles since the 1985 KAS meeting. The Membership Committee strongly urges each mem- ber to serve as a committee of one in the recruitment of new KAS members. 4. BOTANICAL GRANTS COMMITTEE. Dr. Bryant made the report. During 1986 the Botanical Grants Committee received 3 proposals. Of those 3, 2 were funded. The other proposal was not appropriate and was referred to the Athey Com- mittee. The proposals funded are as follows: 1. Mr. Joseph Abner, $432.00, for a research project on the Vascular Flora of Jackson County, Kentucky. This project is directed by Dr. Ronald Jones, Eastern Ken- tucky University. 2. Mr. Alan W. Reed, $225.00 for a research proposal concerned with Increased Aluminum Release from Leaf Litter of Carpinus caroliniana in Response to Acid Rainfall. This project is being directed by Dr. Joe Win- stead, Western Kentucky University. A preliminary report on the work done on the latter grant was given at the November 1986 KAS Botany and Microbiology Section Meeting. The Botanical Grants Committee will not receive grant proposals for the 1987 funding period. Guidelines for grants have been published in the Transactions and KAS News- letters. Members of the Committee are: William S. Bryant, Chairman; Ralph Thompson; and Ronald Jones. 5. MARCIA ATHEY FUND. Dr. Freytag made the report. There were two grants approved and funded for 1986. They were: 1. Dr, Steven I. Usdansky, Department of Geoscience, Murray State University. “Petrologic Characterization of Dike Rocks from the Western Kentucky Fluorspar District.” A 1-year study funded for $1,000.00 . Dr. Joe E. Winstead, Department of Biology, Western Kentucky University. “An Investigation of Sulfur De- position in the Wood of Shortleaf Pine on the Cum- berland Plateau of Kentucky in Relation to Atmospher- ic Sulfate.” A 2-year study funded for $7,500.00 bo 6. SCIENCE EDUCATION COMMITTEE. Dr. George made the report. Awards for Students and Sponsoring Teachers.—At the annual banquet we recognized the student winners of the 5 regional science fairs in Kentucky and the winners of the KJAS Symposium last spring. We honored 10 stu- dents and 10 sponsoring teachers. Each honoree was given a plaque recognizing their achievements. They were also the guests of the Academy at the banquet and were given a free membership in the Academy for 1 year. We appre- ciate all the hard work and initiative shown by these stu- dents and their teachers. ACADEMY AFFAIRS 29 The Pre-College Curriculum.—This program was de- signed by the Council on Higher Education and is set to go into effect by fall, 1987. Students meeting this require- ment are eligible for unconditional admission to Ken- tucky’s public universities. These universities may exempt up to 20% of entering freshmen who have not completed the Pre-College Curriculum. Two units of science are required in this curriculum of which at least one must be from Biology I, Chemistry I or Physics I. CHE published and distributed a brochure which was very misleading. It stated “Science—2 units— Biology I or Chemistry I or Physics I and a science elec- tive.” It was not clear to science teachers, principals, and superintendents that the elective could also be chosen from Biology, Chemistry or Physics. This has since been rectified with a more specific recommendation: Science A. Required course 1. Biology I (2517) or Chemistry I (2521) or Physics I (2532) or advanced placement courses B. Elective courses 1. Biology I (2517) or Chemistry I (2521) or Physics I (2532) could become the elective course after one of the others is taken to meet the required course . Advanced Placement Genera Biology (2513) Advanced Biology (Biology II) (2516) . Advanced Placement General Chemistry (2522) . Advanced Chemistry (Chemistry II) (2533) . Advanced Placement Physics B (2533) . Advanced Placement Physics C (2534) . Advanced Physics (Physics II) (2538) CNMRMAHRwWD However, the flawed brochure will undoubtedly create problems. Advanced Placement.—Increasing numbers of high schools in Kentucky are beginning to offer courses for Advanced Placement (AP) of the College Entrance Ex- amination Board (CEEB). The reason seems to be the newly instituted Commonwealth Diploma. The Commonwealth Diploma requires: 22 units of ap- proved credits, successful completion of all minimum re- quirements of the Pre-College Curriculum required by the Kentucky Council on Higher Education, successful completion of at least 4 AP courses and completion of 3 examinations of the 4 AP courses taken. (NB—it is not required that any of the AP examinations taken be passed.) It has been reported from several sources that some high schools are simply designating their usual high school sci- ence courses as AP. Such practices are a severe distortion of the intentions of AP. Advanced Placement is intended to allow outstanding students that are capable of doing college level work while in high school to do so and get college credit. Standard high school courses would not normally be expected to meet this level of achievement. Our concerns are that AP courses: (1) should have adequate lab facilities—by all means should meet and go beyond the requirements of the Min- imum Equipment List of the Department of Education; (2) should have hands-on lab time equivalent to college courses. Demonstrations of experiments do not suffice. The student is expected to have undergone these hands-on ex- periences in later college courses; (3) should have college-level textbooks. College level work cannot be done by students using high school texts; (4) should have adequate budget for supplies and equipment above what is normally expended in secondary science courses; (5) should be taught by a teacher with a major in the discipline. However, the College Board does not say any- thing about the qualifications of the teacher; and (6) that the teacher must go through the training work- shop in organizing/teaching AP courses. This committee proposes that the academy, along with the Kentucky Association for Progress in Science (KAPS) pass a joint resolution expressing our concerns about AP and inform all science teachers, principals, superinten- dents and the appropriate officials of the Kentucky State Department of Education. This would require an article in both newsletters and mailings to all the above individ- uals. A resolution to the affect will be offered through the Committee on Resolutions. Incentive Loan Program.—This program has been suc- cessful in attracting new teaching majors in science and mathematics. This committee recommends that we en- courage the State Department of Education to continue this program as long as there is a shortage of these teachers. Other science societies have agreed to join with the acad- emy in sponsoring a resolution to this effect. These societies are Kentucky Association for Progress in Science, Ken- tucky Council of Teachers of Mathematics, Kentucky Chapter of the Wildlife Society and The Kentucky Na- tive Plant Society. A resolution to this effect has been forwarded to the Resolutions Committee. Science Advisory Council.—This council has previously functioned as an Advisory Council to the Superintendent of Public Instruction. It was a widely-based committee consisting of classroom teachers, science supervisors, su- perintendents and representatives from government, in- dustry and the science societies. Wide-ranging proposals developed from diverse points of view were able to give input to the Superintendent and his advisors. Some funding is required since classroom teachers (whose presence is vital) must have to pay for a substitute teacher when they attend to meetings and also need travel money. If such a council is in place, we should be able to get our concerns before the Superintendent much more quickly and effi- ciently. Those societies are the same ones that joined in the resolution on the Incentive Loan Program. A resolution to this affect has been forwarded to the Resolutions Com- mittee. 7. COMMITTEE ON RARE AND ENDANGERED SPECIES. Dr. Branson made the report. The Rare and Endangered Species list, with modifica- tions and recommendations, is now in press. It will be in Vol. 47(1-2) of the Transactions. 30 Trans. KENTUCKY ACADEMY OF SCIENCE 48(1-2) 8. AUDIT COMMITTEE. Mr. Weddle made the report. Endowment funds of the Kentucky Academy of Science Foundation are being and have been invested to assure continued growth. However, we believe that certain changes in management policy would allow more accurate ac- counting of these funds. Our concerns are twofold as fol- lows. Historically, awards have not kept pace with interest income and substantial residual funds have accumulated. Currently, ten per cent of earned incomes generated by the Botany Fund is compounded annually. The remainder is accumulated in other interest-bearing accounts or awarded as grants. Income from the Marcia Athey Fund is significantly larger yet no policy exists for its reinvest- ment, nor does policy exist to specifically direct the trea- surer in managing any residual fund. Reinvestment de- cisions regarding residuals have been left totally to the discretion of the treasurer. The potential for additional confusion in record keeping and for increased difficulty in maintenance of the integrity of separate funds is of growing concern. Secondly, financial institutions holding foundation funds provide balance sheets only in July and January. Accord- ingly, reports of activities in these funds provided to the membership at the annual meeting in November are based on untimely information and are, at best, tentative. We recommend that the Executive Committee and the Board of Directors consider the following: 1. A detailed and specific policy for reinvestment of a position of the interest accrued from the Athey Fund and for reinvestment of residuals from all KAS Foun- dation funds should be established. This policy should be sufficiently specific and inclusive to preclude the necessity for decision making, on the part of the trea- surer, and should insure the continued integrity of funds. 2. The Annual Audit of KAS Foundation funds should be completed in January after year end bank statements are available. This information could then be dissem- inated to the membership of publication in the news- letter. A tentative report could be included with the audit report provided the membership in November. 3. Consideration should be given to secure an independent accounting firm to establish a plan for management and reporting of all KAS Endowment Funds. 9. AD HOC COMMITTEE FOR THE REVISION OF THE CONSTITUTION AND BY-LAWS. Dr. Rodriguez made the report. Dr. Rodriguez said that the Committee was studying the constitutions of other Academies and would make a report to the Executive Committee at its January meeting. The committee would try to have a revised copy of the constitution in the spring Newsletter. Dr. Rodriguez made a proposal for increasing the en- dowment funds. He suggested that when an individual’s contributions to the endowment fund reached the amount needed for life membership, that person would then be- come a life member. No action was taken on the proposal. 10. LONG RANGE PLANNING COMMITTEE. Dr. Het- tinger made the report. He reported the committee was continuing its efforts to obtain a central office for the Academy. He said the Ken- tucky Society of Professional Engineers had their head- quarters just outside of Frankfort and had offered to pro- vide telephone answering service and possibly a small room to serve as a repository and office for a KAS representative. This offer would be discussed at the next meeting of the Executive Committee. In order to get a better understanding of how other Academies handled their administrative details, the com- mittee had obtained copies of constitutions and by-laws of other Academies (1) for review as to how they handle membership, Board of Directors, Executive Secretary, Central Office, etc. This information would also be used by the Ad Hoc Committee on the revision of the Consti- tution and By-Laws. Dr. Covell reported that Dr. Rodriguez had agreed to serve as a special assistant to the President for the upcom- ing year. 11. RESOLUTIONS AND NOMINATING COMMITTEE. Dr. Prins submitted the following resolutions which were accepted unanimously. Resolution 1 Whereas, the science societies of Kentucky, namely the Kentucky Academy of Science, Kentucky Association for Progress in Science, Kentucky Association of Physics Teachers, Kentucky Chapter of the Wild Life Society, and Kentucky Native Plant Society are vitally interested in the future of science in Kentucky, and Whereas, this future depends upon the education in sci- ence in the public schools, and Whereas, to aid the diffusion of scientific knowledge, these societies wish to take an active interest in, and give all support possible to the Kentucky Department of Education in science education, and Whereas, science education needs the broad support and insight from many different groups such as classroom teachers, science supervisors, science societies, principals, superintendents, business and lay persons, Therefore be it Resolved: that these science societies pro- pose that the Superintendent of Public Instruction should appoint a permanent Science Advisory Council to advise the Superintendent on all matters relating to science ed- ucation in the public schools. Some minor funding will be necessary for travel expenses. Such funding must be set up as a line item in the annual budget of the Kentucky State Department of Education. Resolution 2 Whereas, the science and mathematics societies of Ken- tucky, namely the Kentucky Academy of Science, Ken- tucky Association for Progress in Science, Kentucky As- sociation of Physics Teachers, Kentucky Council of Teachers ACADEMY AFFAIRS 31 of Mathematics, Kentucky Chapter of the Wild Life So- ciety, and Kentucky Native Plant Society are vitally in- terested in the future of science and mathematics in Ken- tucky, and Whereas, this future depends upon the education in sci- ence and mathematics in the public schools, and Whereas, for many years, there has been a shortage of qualified teachers of science and mathematics, and Whereas, the Incentive Loan Program has been in effect for four years which has been highly successful in attract- ing many fine undergraduates into the teaching fields of science and mathematics. Therefore be it Resolved: that the Kentucky Department of Education be praised for this excellent program and that the aforementioned science and mathematics societies of Kentucky join together and request that the Incentive Loan Program be continued and regularly budgeted until the shortage of science and mathematics teachers be elim- inated. Resolution 3 Whereas, the Kentucky Academy of Science and the Ken- tucky Association for Progress in Science are deeply in- terested in all phases of science education in Kentucky, and Whereas, we support all efforts directed toward improve- ment of education in Kentucky, and Whereas, we support the institution of Advanced Place- ment courses in the Kentucky curriculum, and Whereas, it appears that some high schools in the Com- monwealth are instituting Advanced Placement without the proper budget, preparation, and facilities for such courses, Therefore be it Resolved: that the Kentucky Academy of Science and Kentucky Association for Progress in Science join together to inform all parties—teachers, principals, superintendents and pertinent state officials—of the re- quirements of Advanced Placement courses along with a plea that these requirements should be met. Resolution 4 Whereas, the School Science and Mathematics Association chose Kentucky as the location for its 1986 national meet- ing, and Whereas, the School Science and Mathematics Association has provided the opportunity for this unique joint meeting by inviting the Kentucky Academy of Science, Kentucky Association for Progress in Science, and the Kentucky Council of Teachers of Mathematics to join with it, and Whereas, the Conference Planning Committee consisting of Bob Creek, Ron Gardella, Frank Howard, Mike How- ard, Ron Pelfry, Linda Jensen Sheffield, Sheila Vice and Joe E. Winstead has done an exemplary job of planning the joint meeting, Therefore be it Resolved: that the Kentucky Academy of Science expresses its sincere appreciation to the School Science and Mathematics Association and the planning committee representing all organizations involved and that the Secretary of the Kentucky Academy of Science be instructed to inform the members of the committee and the Presidents of the organizations. Resolution 5 Whereas, the State of Kentucky received an EPSCoR grant of $3 million from the National Science Foundation, and with instate matching funds the EPSCoR program pro- vided over $16 million for research in Kentucky, Whereas, Charles Kupchella and Gary Boggess played key roles in initiating the EPSCoR movement and participated in the grant application process, Therefore be it Resolved: that the Kentucky Academy of Science expresses its sincere appreciation to Charles Kup- chella and Gary Boggess and that the Secretary of the Kentucky Academy of Science be instructed to so do. Dr. Prins offered the following nominations and moved their acceptance. Richard Hannan Kentucky Nature Preserves Commission Vice President: Secretary: Robert Creek Eastern Kentucky University Treasurer: Morris Taylor Eastern Kentucky University Board of Gordon Weddle (1989) Directors: | Campbellsville College Larry Elliott (1990) Western Kentucky University David Legg (1990) Kentucky State University The motion was seconded and, with no further nomi- nations, was passed. NEw BusINEss Dr. Covell reported that Dr. Winstead, on behalf of Western Kentucky University, had extended to the Acad- emy an invitation to hold its 1987 annual meeting at West- ern Kentucky University on 6-7 November. Dr. Covell said the Executive Committee had voted to accept the invitation. President Covell concluded his tenure as President by giving a brief address concerning his past year as president (presented elsewhere in the Transactions). He thanked everyone for their help and then presented President-elect Giesmann with the gavel and welcomed him as President of the Kentucky Academy of Science for 1987. President Giesmann presented Dr. Covell with a plaque for his service as President and contributions to the Acad- emy. President Giesmann gave a short address in which he briefly outlined his goals for the coming year. He said 82 TRANS. KENTUCKY ACADEMY OF SCIENCE 48(1-2) his theme would be “Service to and Through the Acade- all members of the Academy, Following his remarks he my.” His goals were to develop a data base for all members adjourned the meeting at 1040. of the Academy, increase membership, develop a local arrangement handbook for putting on annual meetings and to improve public relations. He requested the help of Robert Creek, Secretary Kentucky Academy of Science Trans. Ky. Acad. Sci., 48(1-2), 1987, 33-35 1986 PRESIDENTIAL ADDRESS TO THE ACADEMY : — « AA CHARLES V. COVELL, JR. Professor of Biology, University of Louisville, Kentucky 40292 What are the goals of the Academy and how are we meeting them? On 8 May, 1914, 25 scientists met at the “State University” in Lexington to found the Academy. Chemist Joseph H. Kastle, Director of the Kentucky Agricultural Experiment Station, was elected as first President; and 5 papers were delivered on such subjects as bone ossification, theories of thermal and electrical conductivity, and the significance of the work of the Exper- iment Station to the agricultural prosperity of the state. The Constitution unanimously adopted at that meeting stated the object of the Academy to be: “to encourage scientific research, to promote the diffusion of useful scientific knowledge, and to unify the scientific interests of the state.” The first Transactions were published in 1924, detailing activities of the first decade of the Academy’s existence. By reading this and subsequent volumes of the Transactions one can trace the interests and activities of Kentucky’s scientific community over the decades. Today, more than 72 years later, the goals of the Academy remain the same. In 1986, how have we adhered to them, and what have we accomplished during the past year? I cannot imagine any year in which there has been more “encouragement of scientific research” in Kentucky. The successful efforts of the Kentucky EPSCoR Committee in stimulating the writing of 146 grant proposals, many of which have received or will receive funding outside the EPSCoR grant of $15.5 million, is the greatest achievement along these lines in the history of Kentucky science. If you have not done so, please read the “EPSCoR Summary” sent with your latest KAS Newsletter. Along with Chuck Kupchella (the “Father of the Kentucky EPSCoR Project’’), Gary Boggess and many other KAS members have worked hard toward the ultimate victory in obtaining the $3 million from NSF, $3 million from state government, $600,000 from industry, and the rest from the institutions involved. This achievement represents not only hard work of high quality by many individuals, but also the fruition of increased cooperation among 33 34 TRANS. KENTUCKY ACADEMY OF SCIENCE 48(1-2) academia, state government and the private sector during the past 3-4 years—a deliberate focus of the Academy’s leadership during this period. In addition to the direct and indirect encouragement of research through the EPSCoR Program, the Academy itself has been able to provide tangible assistance as never before. Besides recognizing the Scientist, High School Teacher, and College Teacher of the Year, and 10 JKAS student prize winners and their mentors, we have been able to grant $8,500 in research funds under the Marcia Athey Fund to two investigators—the largest dollar amount support ever possible for the Academy to grant. For this we are greatly indebted to Raymond Athey for providing the Fund; and to Paul Freytag and the Marcia Athey Fund Committee members for administering it. In the area of “promoting the diffusion of useful scientific knowledge” we continue to publish our Transactions in 2 annual issues. This year financial and printing-house problems resulted in a double setback: our Volume 46(3/4) was released late and with an unacceptable number of errors; and our Volume 47 has been delayed as well. However, the former is being reprinted, and we hope to get back on schedule in 1987 after returning our printing operation back to Allen Press, a specialized and efficient, although more expensive, company. Our Secretary publishes 2 newsletters a year; and the Junior Academy also diffuses information via its own newsletter. Press coverage of Academy activities has been poor in the past, but we expect improvement in the future. Also in the area of diffusing scientific information is the creation of a speaker's bureau list, which should be published soon with over 50 of our members listed as available to speak to school and other groups on a wide range of topics. Finally, the record participation by KAS members in this annual meeting, with 252 papers presented (86 more than last year) attests to the strength of this aspect of our mission. Besides quantity, I have noted a steady increase in the quality of papers presented in recent years. Thanks to all of you who have contributed this year; it has been a most stimulating meeting! The most difficult aspect of the Academy’s mission, I feel, is to “unify the scientific interests in the state.” To some extent, this is accomplished as members from our various sections agree to serve the Academy in various committees and offices. Yet there are segments of Kentucky's scientific community in the private sector and in some areas of education that we have not yet reached. We hope to make contact with them and feel we have had an excellent chance to do so at this combined meeting. Others have yet to be convinced that membership in the Academy is beneficial to them, and have either dropped their memberships or never have joined. You can help us here by bringing in at least one new or reinstated member in 1987. Selling points can include the fact that communication among scientists in the state is important, and sharing research results by presenting papers and publication in the Transactions is worthwhile, and is also a “good place to start” for student scientists trying their wings. As to affecting the course of science in Kentucky, we seem to be having an increasing effect as our numbers grow, and as we increase the involvement of our colleges and universities and our science-related businesses and industries. Last year’s President Joe Winstead began a major effort to enlist these as Institutional and Corporate Affiliates in the Academy, and we have continued that effort this year. Affiliates have provided vital additional income of over $6,000 last year, and $5,550 so far this year from 19 institutions and 2 corporations. The campaign is still underway with our appeal to corporations (and for individual memberships from the private sector as well), Letters are going out to over 300 companies in the Commonwealth, thanks to our Membership Committee, chaired by Doug Dahlman, and President-elect Hettinger. Some unification of science interests surely accrues from the activity of the Kentucky To- morrow Cominission, led by Lt. Governor Steve Beshear, and the membership of KAS members on the Commission’s Science and Technology Committee. And of course the monumental EPSCoR effort cited above has done much toward attaining that objective. These are some of the ways the Academy is meeting the goals established in 1914. Other aspects of our activity include constitutional revision, which has progressed from initial rec- PRESIDENTIAL ADDRESS 35 ommendations presented in September by our ad hoc revision committee consisting of Ted George, Gary Boggess, and J. G. Rodriguez (Chairman). Your Executive Committee and Board of Trustees hope to have these revisions ready for your approval in the coming year. A new officer, that of Executive Secretary, may be established through this revision. For now President- elect Giesmann and I have jointly appointed Dr. Rodriguez as a Special Assistant to the President for 1 year. His duties are yet to be fully defined; but he will assist in public relations and other functions to carry out the goals of the Academy. To develop financial recommendations to guide our Treasurer, an ad hoc Committee on Financial Policy has just been appointed, made up of Paul Freytag (Chairman), Manuel Schwartz, and Alan Reed. A further activity pertaining to strengthening the Academy is the exploration of a possible “home office” by our ad hoc Committee for Long Range Planning (Bill Hettinger, Chair). Such an office will be selected after our constitutional revisions have been completed. During the past year Academy members participated in the successful drive for improved funding of higher education by the Legislature. Several Academy members formed a small contingent at the “Capital Caravan” rally held in Frankfort on 5 February. We have initiated the development of a Collegiate Academy branch to bring undergraduate college students into Academy activities. Herb Leopold is heading that effort. I explored the possibility of establishing a summer Nature Camp at Pine Mountain Settlement School in conjunction with the Kentucky Federation of Garden Clubs. However, that organization did not elect to pursue this idea, despite the support of its President. In 1986 we signed a document by which we joined 16 other state academies of science and 72 Nobel laureates as amici curiae in a brief filed in the case of Edwards vs. Aguillard et al. pending before the U.S. Supreme Court. This case seeks to overturn a Louisiana law requiring public school teachers to give “balanced treatment” in class to evolution and “creation science.” This has been an exciting and stimulating Annual Meeting, capping an equaliy exciting and stimulating year. I am deeply grateful for the opportunity to have been your President, and wish to express this gratitude to all of you who have done so much this past year to further the goals of the Academy. I particularly wish to single out Bob Creek and Joe Winstead for their help in many ways as I pursued this job, and also who had the most to do in arranging the Academy’s participation in this joint conference. Thanks to all you committee chairs and members for your good service. I want to encourage all of you to continue sharing your scientific interests and achievements with the rest of us through publication and presentation of papers in the years ahead. Also, we want to broaden the participation of our members in the governance of Academy affairs; so let us know your ideas, and indicate your desire to participate. Now, as is our tradition, I will turn the gavel of the Academy over to your new President, Larry Giesmann of Northern Kentucky University. Good luck to you, Larry, and to all Academy officers, for continuing success in 1987. Trans. Ky. Acad.

LUKEN, Department of Biological Sciences, Northern Kentucky University, High- land Heights, KY 41076. Differences in amount and vertical distribution of aboveground biomass were measured between patches of crownvetch (Coronilla varia) and Kentucky-31 tall fescue (Festuca arundinacea) on a revegetated roadside em- bankment in Northern Kentucky. Growth of tall fescue was stimulated when growing in crownvetch patches (field) and when growing in soils collected from crownvetch patches (greenhouse). In comparison, growth of crown- vetch was inhibited when growing in tall-fescue patches (field) and when growing in soils collected from tall-fescue patches (greenhouse). These data coupled with a measured growth response of tall fescue to nitrogen fertilization sug- gest that tall fescue will eventually invade and dominate crownvetch patches. The role of Carpinus caroliniana in release of aluminum in response to acid rain. ALAN W. REED* and JOE E. WINSTEAD, Departments of Biology, Lindsey Wilson College, Columbia, KY 42728, and Western Kentucky University, Bowling Green, KY 42101. To test Carpinus caroliniana Walt. (ironwood) as an aluminum contributor in acidic aquatic systems, we placed leaf samples in solution buffered to pH 3.5, 4.4, and 7.0 and one of 4.4 inoculated with 10 g of limestone. After 75 days, microbial activity altered solution pH as follows: 3.5 to 4.7; 4.4 to 5.0; 7.0 to 4.8; and 4.4 to 6.1. Aluminum assay of leachate was by atomic absorption techniques. More acidic leachates contained higher aluminum levels with 1 g leaf samples contributing 0.341 mg/liter under initial pH of 3.5 compared to 0.153 mg/liter in pH solution with limestone. CHEMISTRY Detection of chloroalkane metabolites by derivatization and high-performance liquid chromatography. MARK A. TOON* and ROBERT F. VOLP, Department of Chem- istry, Murray State University, Murray, KY 42071. 2-Chloropropane is metabolized to acetone. Our goal was to obtain an analytical method of detecting the acetone produced by liver microsomes. By reacting acetone with dansyl hydrazine, we were able to form a fluorescent hy- drozone derivative, which could then be analyzed using reversed-phase HPLC and a fluorescence detector. The derivatization procedure was optimized with respect to reagent concentration, pH, and water content and gave reproducible, quantitative results. After 60 minutes in- cubation of 5.0 mM 2-chloropropane (5 mg protein/ml), 47 117 uM acetone was present in the mixture. By varying the incubation time, this method can be used to determine the rate of 2-chloropropane metabolism. Components of fresh vs. aged coal extracts. DAVID IGO*, WILLIAM D. SCHULZ, and JOAN REEDER, De- partment of Chemistry, Eastern Kentucky University, Richmond, KY 40475. Authorities believe soluble portions of coals reflect struc- ture of insoluble portions and that loss of thermoplasticity upon heating or aging are mechanistically similar. To study these phenomena, Kentucky coal KCER 9091 was crushed, “artificially aged” by stirring under oxygen for 7, 21 and 24 days. Control and “aged” samples were soxhlet extract- ed, concentrated and analyzed by capillary gas chroma- tography /mass spectrometry. Chief differences in extracts were lower boiling alkenes, dienes and aromatics present in control samples, and not in aged samples. We believe that these compounds are oxidatively incorporated into cross-linked coal structure during aging. Fugitive emissions from packaging of household organo- phosphate products. MICHAEL W. NOLD and WIL- LIAM D. SCHULZ*, Department of Chemistry, Eastern Kentucky University, Richmond, KY 40475. Several samples of “controlled-release” household pes- ticide products containing organic phosphate ester (cho- linesterase inhibitor) active ingredients were examined for fugative toxic emissions. Products included “‘flea collars’ and “pest strips” of various brands. These products are sealed in polymer-foil or treated paper packages. Sealed packages were washed with methylene chloride, concen- trated, and analyzed by capillary gas chromatography / mass spectrometry. All products had traces of active in- gredient on outsides of sealed packages. Concentrations ranged from 15 mg to traces of hydrolyzed ingredient. We have yet to determine if these results are due to dif- fusion through the package or deposition during pack- aging. GEOGRAPHY Regional semantics of “barren” and “desert” in 18th and 19th century North American landscape descriptions. CONRAD MOORE, Department of Geography and Ge- ology, Western Kentucky University, Bowling Green, KY 42101. Previous interpretations of the meaning of “barren” and “desert” in historic North American landscape descriptions have emphasized the importance of an absence of trees. An examination of 371 travel accounts written during 1774- 1880, revealed that the primary indicators of “barren” landscapes were the presence of shrubs and small trees in the humid East, a lack of grass in the subhumid-semiarid 48 Trans. KENTUCKY ACADEMY OF SCIENCE 48(1-2) Central Plains, and the presence of sand hills or plains and xerophytes in the semiarid-arid Far West. Dominant “des- ert” criteria were a lack of settlement in the East and the presence of unconsolidated sand in the Central Plains and Far West. Place names of Fayette County, Kentucky. WILLIAM A. WITHINGTON, Department of Geography, Univer- sity of Kentucky, Lexington, KY 40506-0027. Place name studies or gazetteers, frequent at national and state or provincial levels, are few for the U.S. county level. This place-name study focusing on Fayette County in east-central Kentucky adds to those few. The purpose is to identify place names of sufficient prominence for inclusion in a county gazetteer. Fayette County place names and their numbers, classifications, and sources are re- viewed. Onomastic questions of name sources and ques- tions of inclusion of historic but non-current or detailed feature names are examined, indicating several possible approaches to place-name studies in such localized areas as Fayette County. GEOLOGY Carbonate paleosols in the Mississippian carbonates of northeastern Kentucky. FRANK R. ETTENSOHN, De- partment of Geology, University of Kentucky, Lexington, KY 40506. Subaerial exposure crusts are common atop disconform- ities separating Meramecian and early Chesterian (Missis- sippian) members of the Slade Formation in northeastern Kentucky. Although the crusts commonly attributed to diagenetic processes, the widespread presence of soil fea- tures suggests a pedogenic origin. Significant pedogenic features include root traces, soil structure, and soil hori- zons. Evidence for rooting includes root molds, root tu- bules, and alveolar texture. Soil structures most commonly occur as megascopic peds. Most soil profiles are immature or truncated, and only the C horizon remains; locally relict A and B horizons are present. The crusts themselves rep- resent carbonate illuviated in the C horizon during dry, evaporative periods. Petroleum exploration and production in the U.S.A. GRAHAM HUNT*, Department of Geology, University of Louisville, Louisville, KY 40292. With the collapse of oil prices there are many and widely various projections and predictions for the years ahead in this historically cyclical business. For this country recent data indicate: (1) a rise in petroleum demand (3% an- nually); (2) a decline in oil production (2% from 8.9 million barrels per day, 1985, to 8.5 million barrels per day); (3) a decline in development drilling (62%, the lowest level in the last 40 years, 954 rigs operating in 1986 compared with 1962 rigs operating a year ago); and (4) a highly fluctuating oil price (prices with lows of $7/barrel to highs near $18/barrel). The demand for energy alternatives in the U.S.A., such as natural gas and coal, may start to increase sharply (1990 to 2000) in reply to the rising oil prices and declining production and increased imports. As the oil begins to become more scarce there will be more drilling for natural gas at depths near 15,000 feet in host sedimentary rocks. MATHEMATICS & COMPUTER SCIENCE ENGINEERING Applications of graph theory in computer science. JOHN H. CRENSHAW, Department of Computer Science, Western Kentucky University, Bowling Green, KY 42101. Deadlock detection is a practical application that can be used as an example in teaching graph theory. In graph- theoretical terms, a deadlock occurs when the adjacency matrix describing the physical system possesses a cycle. If there are M processes in a system, then the adjacency matrix A isan M x M matrix where A(J, J) = 1 if process I is waiting for a resource possessed by process J and 0 otherwise. The classical technique is to compute A™. If A™ is non-zero then A possesses a cycle. However, the time constraints of a practical system make this approach inef- ficient and impractical; faster techniques must be devised. A Pascal course for gifted and talented middle-school students. VIRGINIA EATON, Department of Computer Science, Western Kentucky University, Bowling Green, KY 42101. During summers 1984, 1985, and 1986 Western Ken- tucky University offered a Pascal course for middle school students. The course is offered as part of WKU’s Summer Program for Verbally and Mathematically Precocious Youth, which is a cooperative effort with the Duke Uni- versity Talent Identification Program. Students alternate between attending lectures and doing lab work. They are in class for 6 hours per day for 3 weeks. The material covered is the same material taught in WKU’s introductory Pascal course. The students learn TURBO Pascal on mi- crocomputers and VAX Pascal on a VAX 11/785. Expected utility and decision making. WALTER FEIBES, Department of Business Administration, Bellar- mine College, Louisville, KY 40205. When one or more of the outcomes of a decision problem results in either an extraordinary large monetary or utility loss, the expected monetary value criterion for obtaining an optimal decision is replaced by Von Ne~.nann’s ex- pected utility criterion. Criticism of the classical utility assumptions are discussed and illustrated with the Allais paradox and Raiffa’s “money pump” problem. Specifi- cally, the assumptions of transitivity and the existence of a unique utility function are questioned and possible al- ternative assumptions are proposed. Partnership with industry: adapting the traditional cur- riculum for non-traditional on-site courses. CAROL W. WILSON, Department of Computer Science, Western Kentucky University, Bowling Green, KY 42101. PROGRAM AND ABSTRACTS, ANNUAL MEETING 49 Teaching at an industrial site can be challenging and rewarding, During academic year 1985-1986, I taught Introduction to Programming and Programming I (BA- SIC) at the Logan Aluminum plant in Russellville, KY. Class examples and programming assignments were cho- sen carefully to relate to the adult experience or the in- dustrial environment. Students were delighted when they realized that they were capable of generating the pro- duction reports that they used in their daily work. Reaction was so positive to these first courses that three additional university courses hav been offered at the Logan site and more courses are planned for the future. Classroom enrichments from topology. CARROLL G. WELLS*, Department of Mathematics, Western Ken- tucky University, Bowling Green, KY 42101. Topology is the geometry which studies what happens when objects are twisted, stretched, bent, cut, glued, etc. Using a strip of paper, form the following objects: (1) strip; (2) band—bend the strip without twisting and tape the seam; (3) band with full twist—bend and put a full twist in the strip and tape the seam; (4) Mobius strip—bend and put a half twist in the strip and tape the seam. Now de- termine how many sides each has and what happens when each is cut lengthwise. PHYSIOLOGY, BIOPHYSICS & PHARMACOLOGY Reflex cardiac effects of left atrial distension. MICHAEL A. KURZ*, WILLIAM B. WEAD, and ANDREW M. ROBERTS, Department of Physiology and Biophysics, University of Louisville, Louisville, KY 40292. To determine the effects of left atrial distension on myo- cardial contractility, a balloon-tipped catheter was placed in the left atrial appendage of anesthetized dogs. Left ventricular pressure was recorded for determination of Vmax. Inflation of the balloon with warm saline increased Vmax and heart rate. External pacing of the ventricles did not eliminate the inotropic effect. Following bilateral cer- vical vagotomy, distension had no effect on heart rate but caused an increase in Vmax. Sympathectomy eliminated all reflex cardiac effects. We conclude that left atrial dis- tension causes a vagally mediated increase in heart rate and a sympathetically mediated increase in contractility. Physiology of the developing urinary bladder in the amphibian Rana catesbiana. THERESA L. POWELL* and JOHN J. JUST, Thomas Hunt Morgan School of Bi- ological Sciences, University of Kentucky, Lexington, KY 40506. Transition of fully aquatic larval amphibians to semi- terrestrial adults involves osmoregulatory alterations. We are interested in how the developing urinary bladder, which serves as a water storage organ in adults, contributes to this process. Isolated bladders transport water at a rate of 32 ul/cm?/min in vitro. In 2-week-old froglet bladders arginine vasotocin (AVT), 10~° M, increased the rate of water loss to 1.25 ul/em?/min. However, preliminary ex- periments on stages XXII-XXV (Taylor-Kollros) show no significant response to AVT over control rates. These data along with electron microscopy suggest that completion of metamorphosis results in a fully developed and func- tional bladder. PSYCHOLOGY Entorhinal cortex lesions disrupt spatial learning and DRL-20 performance. M. LAROCCA*, A. NONNEMAN, T. LANDERS, and W. ISAAC, Department of Psychology, University of Kentucky, Lexington, KY 40506-0044. The hippocampus seems to be critical for working mem- ory (comparison of current situation with results of variable preceding events) but not reference memory (situation is stable/predictable). Lesions of the entorhinal cortex elim- inate the major sensory input to the hippocampus. The consequences of such lesions in rats were studied with respect to retention of a preoperatively learned, spatial orientation, reference memory task and a postoperatively learned, DRL-20, working memory task. The lesions caused a transient retention deficit on the spatial task but totally prevented learning of DRL-20. The entorhinal cortex ap- parently provides information to the hippocampus critical for efficient working memory. SCIENCE EDUCATION The construction and use of economical electrophoresis apparatus. DAVID R. HARTMAN, Department of Chem- istry, Western Kentucky University, Bowling Green, KY 42101. Plans and a materials list were presented for the con- struction of an electrophoresis chamber to use paper, cel- lulose acetate, or thin layer strips. Amino acids, blood proteins, and enzymes can be separated in the economical clear plastic chamber. Designs for an economical power supply and uses for the equipment were discussed. ZOOLOGY & ENTOMOLOGY Ohio River fish population studies at the Thomas More College Aquatic Biology Station, Campbell County, KY. JOHN W. FERNER* and STEVEN C. ROSCHKE, De- partment of Biology, Thomas More College, Crestview Hills, KY 41017. The Thomas More College Aquatic Biology Station is located at mile 450.5 of the Ohio River near California, KY. Fish populations have been monitored since 1974 at this location and nearby power plants during the summer months. While most sampling has been done with elec- troshocking, some collections by hoop nets, seines, and gill nets and on power-plant intake-screens have also been made. A total of 11,064 fishes representing 49 species has been captured over this 13-year period, the majority in the past 3 years. The most abundant species were Doro- 50 TRANS.

Osmoregulation by the bullfrog tadpole, Rana cates- beiana. JANIS L. GOLDSMITH* and JOHN J. JUST, Thomas Hunt Morgan School of Biological Sciences, Uni- versity of Kentucky, Lexington, KY 40506. Osmoregulatory capacity of tadpoles and froglets was studied using osmotic saline stress. All stages were osmo- regulators in solutions between 8 and 200 mOsm/liter; above these concentrations, all were osmoconformers. In an attempt to determine onset of adult urinary bladder function, time-course studies were performed in a 250 mOsm/liter medium. Urine could be isolated only from bladders of newly metamorphosed froglets. In 1-week-old froglets, urine osmolarity increased from 30 to 100 mOsm/ liter during short-term osmotic stress while the plasma osmolarity temporarily decreased. Thus, although the bladder develops early (state XII, Taylor-Kollros), it does not appear to be used as an osmoregulatory organ until after metamorphosis. Trans. Ky. Acad. Sci., 48(1-2), 1987, 50 Altered integumental pigmentation of Lirceus lineatus. DAVID F,. OETINGER, Department of Biology, Ken- tucky Wesleyan College, Owensboro, KY 42302. Lirceus lineatus (Say 1818) (Isopoda, Asellidae) were collected from tributaries of Panther Creek (Daviess Coun- ty, KY) during the winter months, 1985 and 1986. There were high levels of infection (11-42%) of isopods with acanthocephalans, Acanthocephalus dirus (Van Cleave 1931). Ninety-six per cent of the infected isopods had altered integumental pigmentation: 10 were more lightly pigmented (as has been described for North American asellids infected with acanthocephalans); 37 were more darkly pigmented (as has been described for European asellids infected with acanthocephalans). This is the first report of acanthocephalan-infected isopods, from the same populations, exhibiting both lighter and darker extremes of altered integumental pigmentation. Examination of in- fected isopods failed to relate altered pigmentation to size or sex of isopods, different strains of isopods, or size and sex of parasites.

THIERET Department of Biological Sciences, Northern Kentucky University, Highland Heights, Kentucky 41076 ABSTRACT There was little evidence that staghorn sumac (Rhus typhina L.) colonies growing on revegetated roadside embankments in Northern Kentucky were facilitating tree invasion. Rather, the primary effect appeared to be inhibition of crownvetch (Coronilla varia L.) and Kentucky-31 tall fescue (Festuca arundinacea Schreb.), which in turn allowed other herbaceous and shrub species to invade the colonies. Amur honeysuckle (Lonicera maackii (Rupr.) Maxim.) was an important bird-dispersed invader, but wind-dispersed herbaceous species were also present in the seedbank and vegetation. Unique patches of vegetation are generated by staghorn sumac, but the background of introduced species and the landscape position of these colonies will likely preclude tree invasion for many years. INTRODUCTION Two previous studies documented indirect facilitation of tree seedling establishment by sumac (Rhus) species (1, 2). Colonies of sumac apparently attracted seed-carrying animals and also eliminated dense stands of perennial herbs and grasses that were inhibiting colonization by trees. This role of sumac species in patch succession, however, may not be universal. Even when sumacs are present, rates of tree invasion might be modified by the severity of initial disturbance, the availability of seeds and seed dispersers, and the background of intro- duced plant species. The purpose of our study was to determine from seed banks and vegetation analyses whether staghorn sumac (Rhus typhina L.) was modifying colonization of revegetated road- side embankments in Northern Kentucky. Be- cause our research sites were revegetated with highly competitive perennial grasses and herbs, and also because the staghorn sumac colonies were isolated from natural seed sources, we dl hypothesized that staghorn sumac growing on these road embankments may not be an im- portant successional link in the development of a deciduous forest. Such data are clearly needed as ecologists experiment with tech- niques to restore natural plant communities following severe disturbance (3, 4). METHODS Staghorn sumac colonies we sampled were located on roadside embankments within 8 miles of the Northern Kentucky University (NKU) campus, Highland Heights, Campbell County, Kentucky. Maximum colony ages, as indicated by increment borings of the largest ramets, indicated all were 8-10 years old. Vegetation around the colonies and records of the district road engineer (Ralph Dietz, pers. comm.), indicated that the sites were revege- tated with either crownvetch (Coronilla varia L.) or Kentucky-31 tall fescue (Festuca arun- dinacea Schreb.). Scarification of these sites during road construction was severe; but we 52 TRANS. KENTUCKY ACADEMY OF SCIENCE 48(3-4) TaBLE 1.

KENTUCKY ACADEMY OF SCIENCE 48(3-—4) 1. Successive units inspected must be inde- pendent of each other. 2. Each unit must be classified into only one of r categories. 3. A continuous production process is being sampled. DEVELOPMENT The multinomial distribution can be ex- pressed as: P(X, > X, i n,) Dee =n), Xo =MNy,... n! Sinan int... n! In the special case where r = 2, equation [1] reduces to the binomial distribution which pro- vides the basis for the usual development of the p and np charts (4). However, if the general case is maintained, it is possible to develop np; chart families. The mean of the ith variable in the multi- nomial distribution is Mw, = np [2] and the variance is o° = np(1 — p,) [3] Making use of equations [2] and [3] and sigma limits, families or sets of r — 1 np, control charts can be developed. The ith mean cor- responds to the center line for the np, chart. Sigma limits for the np, charts can be set at multiples of o; or probability limits may be used. The latter technique is used in this paper since computer programs were developed to perform the many calculations involved in ob- taining exact probability limits. Operating characteristics for a chart family for a given set of p,’s are calculated by the following re- lationship: n! p=2 n 7 Pi"'P2"? Dey Pp," [4] n,! no! .. where >’ in [4] represents a sum over all fea- sible combinations of n; values subject to: LeL, =n = UCh. y t= r nen i=1 The calculation for a, the probability of a Type I error, is shown below. n! ! n,! no! .. a= Bi [5] BB"? .n! ILLUSTRATIONS Case I: r = 2 In this case equation [1] reduces to the bi- nomial distribution. The result is a typical np chart as described in statistical quality control texts (1). Case II: r = 3 This case establishes a 3-dimensional control concept. In practice, one might develop a fam- ily of r (3) charts with control limits set at some specified number of items as shown in Figure 1. For example, items produced by a certain process might be of 3 different classifications: acceptable, reworkable, or scrap. A sample of size n would be drawn. The sample would be inspected and each item classified into one of the 8 classes. Then, the number of reworkable items and the number of scrap items would be plotted. The family of np; charts (Fig. 1) would be set up and interpreted for control. In this case, for a process to be considered in control, three conditions must hold: Cin = == UCL, [6] and Ch, = 5, UCL, (7] and ECL = 34 = UGK. [8] The last condition can be expressed in terms of LCL;, UCL; and x, + Xx. Since Xz = NM — X, — Xg then LCL, =n — x, — x, = UCL, and me UCle = x xe =n se (9) Therefore, the third condition above can be stated as n— UCL,= x, +s =n — CIs 10) The result is that a non-rectangular acceptance C QO te = ! ) meen ne Ba eee ees Scrap Chart UCL) = 4 nes = LCL = 0 - LCL i 3 np. + np Pr 12) ne — UCL 3 Interaction Chart Sampling ; 2 3 g 2 Sequence Fic. 1.

In the most general case, it would be a hexagonal region, when plotted on x,, x, axes (Fig. 2). Conceptually, the operating characteristics for this family of np, charts would be an OC surface, rather than an OC curve as in the binomial case. The calculations for the OC sur- face would be made using equation [4] and considering the 3 conditions stated above in equations [6], [7] and [10]. The number of cal- culations needed to completely develop the OC surface would be much higher than the number required to develop a typical OC curve.

Further, assume that the process has been running at a 10% scrap rate, a 20% rework rate and an acceptable rate of 70%. For simplicity of calculations, a sample size n = 10 will be used. Making use of equations [2] and [3], the mean and variance associated with scrap and rework are: uw, = 1010.1) =1 > = 10(0.2) = 2 us; = 10(0.7) =7 MILTINOMIAL BasEp ArrripuTes—Kolarik and Jaisingh 59 Fic. 3. OC surface “8” probabilities for the example problem (np, = 1, LCL, = 0, UCL, UCL, = 4, np, = 7, LCL, = 4, UCL, = 10) ¢2 = 10(0.1)(0.9) = 0.9 and o, = 0.949 pee 10(019)(018) = 1.6 and o, = 1.265 o3° = 10(0.7)(0.3) = 2.1 and o; = 1.449 where i = 1 represents scrap, i = 2 represents rework and i = 3 represents acceptable prod- uct. Considering an np; chart, assume the control limits are set as follows: np, = | LCL, = 0 UCL, =3 np, = 2 LCL, = 0 VCE; =4 np; = 7 LCL, = 4 UCL, = 10 These settings would represent about a 2 sigma setting for the scrap parameter, and about a 1.6 sigma setting for the rework parameter and about a 2 sigma setting for the acceptable pa- rameter products when calculated in a fashion similar to that used for a conventional np chart. Using a probability limit approach and a FOR- TRAN computer program, developed by the authors, Type I and Type II error probabilities can be calculated. The program was written in MICROSOFT FORTRAN77 v3.2 and runs on an IBM PC with an 8087 co-processor. One program, called BETA, calculates one minus the Type I error probability (1 — a) when the 3, np, = 2, LCL, = 0, process is centered at np, and np. This pro- gram will calculate a single “8” value or the user may specify the option of having the pro- gram generate an entire OC surface such as the one shown in Figure 3. When utilized on a microcomputer the program will interact with the user so that the user may develop a single point on the OC surface or an entire OC sur- face. The program utilizes equation [4] recur- sively and the 3 previously discussed control conditions. It checks to see that only feasible combinations of n,, n,, and ng are considered, when the distribution is centered at x, and x, combinations. This example demonstrates the case where r = 3. The idea of an a error or “false alarm” when the process is centered at np, and npg is more complex than the usual np chart case (r = 2). Figure 2 shows a conceptual picture of the general situation, where the a “area” is the non-dotted region. The non-dotted area can be divided into 10 subareas, numbered 1- 10 as shown in Figure 2. Note that subareas 2, 4, 6, and 8 represent cases where one parameter (scrap or rework) is still within control limits but the other is outside control limits. Subareas 9 and 10 rep- 60 TRANS.

In order to assess the portion of a which lies in each of these 10 regions, another FOR- TRAN computer program was developed. This program is named ALPHA. It was developed to run interactively under MICROSOFT FORTRAN?77 v3.2 on the IBM PC microcom- puter. Results for the example problem are shown in Figure 4. Figure 4 shows the results in a graphical format for each of the 10 sub- areas, as previously discussed. It should be not- ed that since the control limits for both scrap and rework were set at 0, ALPHA1, ALPHA2, ALPHA8, ALPHA7, and ALPHAS are zero. In addition, ALPHAS is very small thus indi- a Area Identifiers Scrap x = Graphical results of the ALPHA (a) sub-areas for example (np, = 1, np, = 2). cating a very low probability of an a error or “false alarm” outside both upper control limits simultaneously. The ALPHA 10 region is equal to 0 because the UCL; = 0. The ALPHA9Y region is present since the LCL, was set greater than 0. The second computer program utilizes equation [4] in a manner similar to that of the first computer program, however, the second program must calculate the probabilities out- side the control limits in each of the 10 areas, shown in Figure 2. Both programs are available from the authors. Case III: r = 4 The development of this case is analogous to that of Case II. As r increases, the number of np, charts increase and the effort in estab- MILTINOMIAL BasED ATTRIBUTES—Kolarik and Jaisingh 61 lishing and maintaining them increases. The conceptual operating characteristics surpass a surface and become abstract in shape. The op- erating characteristics of Case HI np, chart families are similar to those of Case I, but the number of calculations involved becomes ex- tremely large. CONCLUSIONS The preceding sections of this paper have expanded the scope of attributes control charts. The expansion from a binomial to a multino- mial basis allows one to address situations with 3 or more item classifications. Such situations are common in many sorting operations in- volving manufactured items. In addition, ser- vices are sometimes rated by classifications such as good, fair, and poor. The np; chart families previously developed are applicable to these situations, provided the assumptions listed pre- viously are valid. The mathematics involved with the np, chart families is relatively simple. Charts can be readily set up and maintained. However, the number of calculations involved with operat- ing characteristics become extremely large as the number of classifications and the sample size n increase. The example and computer programs provided develop the case where three classifications occur and demonstrate the procedure for a small sample size. LITERATURE CITED 1. Duncan A. J. 1974.

BATCH Department of Biological Sciences, Eastern Kentucky University, Richmond, Kentucky 40475 AND SAMUEL M. CALL Kentucky Natural Resources and Environmental Protection Cabinet, Division of Environmental Services, Frankfort, Kentucky 40601 ABSTRACT Data are presented for 6 families, 16 genera and 29 species of aquatic gastropods, 4 of which are in the threatened category. Cipangopaludina chinensis malleata (Reeve, 1862) and Gyraulus deflectus (Say, 1824) are reported for the first time from Kentucky. Subfossil specimens of Io from Pulaski County, Kentucky are discussed. Data and notes on 2 families, 3 genera and 7 species of sphaeriacean clams are presented. Pisidium casertaneum (Poli, 1791) is reported from Kentucky. INTRODUCTION In view of the ongoing attempts to unscram- ble the problem of endangered species in Ken- tucky (1), it seems appropriate to present data on groups of organisms for which the published records are sparse or old. In the case of the Mollusca of Kentucky, information on the Unionidae (“mussels’’) has far outstripped that on the Gastropoda, particularly in the aquatic species. In recent years, a few authors (2, 3, 4, 5, 6, 7, 8, 9, 10) have attempted to provide additional ecological and distributional infor- mation on aquatic snails, including species newly reported from Kentucky (11). This con- tribution provides new distributional data for 6 families, 16 genera and 29 species of aquatic gastropods. Four of the species were previously unreported from Kentucky, and 2 of them are under consideration for federal listing (1). Data are presented also for 2 genera and 6 species of fingernail clams.

RESULTS In the discussion that follows, species are correlated with collecting sites by station num- bers, and the figures in parentheses represent the number of specimens collected. in VIVIPARIDAE Three native genera of this family are known Kentucky, Campeloma Rafinesque 1819, Lioplax Troschel 1856, and Viviparus Mont- fort 1810. This report adds a fourth genus for Kentucky, Cipangopaludina Hannibal 1912. 64 TRANS. KENTUCKY ACADEMY OF SCIENCE 48(3-4) Cipangopaludina chinensis malleata (Reeve 1862) Collecting Sites.—1 (4), 2 (1), 3 (A). This Asian species was introduced into Cal- ifornia prior to 1900 and in the interim became dispersed to many other sections of the country (12). This large (39 mm or more), live-bearing snail prefers habitats in permanent ponds and lakes or sluggish portions of rivers with mud bottoms that have a minimal calcium concen- tration of 5.0 ppm (13). The food is bottom detritus and associated algae. Because of the environmental conditions observed at the col- lecting sites in Ballard and Jefferson counties, we may safely assume that the species is a permanent addition to the gastropod fauna of Kentucky. Campeloma decisum (Say 1817) Collecting Sites.—4 (2), 5 (5), 6 (2), 7 (3). Campeloma decisum, another live-bearing species, ranges through much of the eastern United States and adjacent Canada (12). The range in Kentucky based upon the older lit- erature is misleading but has been clarified recently by Burch (14). Campeloma integrum (Say 1821) and C. obesum Lewis 1865 are 2 synonyms applicable to the Kentucky fauna. Campeloma crassula Rafinesque 1819 Collecting Sites.—7 (1), 8 (1), 9 (1). Previously reported as C. ponderosa (Say 1821) (15), C. crassula is considered to be an Ohio River derivative in the fauna rather than a Cumberland or Tennessee river mollusk, al- though the species occurs marginally in the Cumberland (4, 16). Lioplax subcarinata occidentalis Pilsbry 1935 Collecting Sites.—10 (1). This relatively thin, small (25 mm or less in length), usually pale-green snail is not very abundant in Kentucky, although it is relatively abundant in the lower Licking River though uncommon elsewhere. Clench (12, 17) and Clench and Turner (18) considered this sub- species to be a synonym of L. sulcosa Menke 1828, mostly because typical L. swbcarinata is smaller (around 20-21 mm in length). This snail bears watching by concerned scientists since its populations appear to be dwindling in waters where it was once common, often in association with unionid beds, especially in the lower Kentucky River. POMATIOPSIDAE Although these small, elongated and oper- culated snails are considered by certain authors (19) to be terrestrial, their habits indicate an amphibious life style. Until very recently, Po- matiopsis was included in the family Hydro- biidae. Burch (14, 20) and Hubricht (19) res- urrected the Pomatiopsidae Stimpson 1865. Pomatiopsis lapidaria (Say 1817) Collecting Sites.—11 (2), 12 (3), 18 (1), 14 CD mh (ear This amphibious, calciphilic species (19) is often found varying distances away from bod- ies of water, usually on a mud substrate. In addition to the localities cited above, Hubricht (19) recently included Carter, Edmonson, Jef- ferson, Rockcastle and Pike counties in the known Kentucky distribution. PLEUROCERIDAE The Pleuroceridae is one of the most per- vasive groups of aquatic gastropods in the Mis- sissippi River drainage, and systematically the family is almost an enigma. Literally hundreds of nominal species have been described; hence, the list of synonyms for any currently recog- nized species is usually long. The center of distribution and speciation appears to be the Alabama-Coosa River system and, secondarily, the Tennessee and middle Cumberland river systems (21), with depauperacy becoming more noticeable northward. Because pleurocerids have used various Kentucky streams as migra- tion routes in pre- and post-Pleistocene times and as refugia (Green River, Licking River) at various times (21), the state has a fairly large representation of these snails. There is considerable debate over generic designations (and recognition of species) in the family. In his massive presentation, Burch (14) resurrected a number of generic names that have not been used for many years; recent authors are divided on the use of resurrected names. Because of the more familiar desig- nations of Calvin Goodrich (22 and afterward), we have elected to follow that author’s logic. In the text that follows, however, we have in- AQUATIC SNAILS IN KeNtucKy—Branson et al. 65 cluded in parentheses Burch’s (14) generic des- ignations of the various species discussed. Goniobasis (=Elimia) semicarinata (Say ie Collecting Sites. —5 ates on aleeQley ye at (21), 19 (11), 20 ae 43), 22 (1 S 23 (9 : 24 (5), 25 (59), 26 (8 37 . ue 8 (86), 29 (3), 30 (2), 31 (2), 32 (1), 33 (3) (2). This is the most abundant Sone of the whole Kentucky River basin (3, 5, 6), the Salt River (15), and “tributaries of Ohio River, Scioto River, Ohio, to Big Blue River, Indiana; Licking River to Salt River in Kentucky; two creeks of Green River of Kentucky” (22). The latter distribution, written by Goodrich, has been cited by practically every paper dealing with aquatic gastropods from Kentucky, and it has greatly biased the opinions of collectors in other drainages within the state. For ex- ample, Krieger and Burbank (24) designated specimens from Prior Creek in Trigg County as this species, but Blair and Sickel (2) referred carinate specimens from the same general area as deviate specimens of Goniobasis laqueata (see below). In some previous work (4), abun- dant specimens from various Cumberland Riv- er streams were found to be indistinguishable from typical Kentucky River specimens and ones from the Blue River and the East Fork of the White River in Indiana (26). Thus, the specimens we have designated as G. semicarinata from Donaldson Creek, a trib- utary of Lake Barkley in Trigg County, tend to substantiate the previous report of the species from that environs (24). Goniobasis semicar- inata has a much wider distribution in the Ohio River basin than previously discerned and research needs to be accomplished to clarify the recognition of the various forms of the species. Goniobasis (=Elimia) ebenum (Lea 1841) Collecting Sites. —35 (3), 36 (4), 37 (2), 38 (2), 39 (20), 40 (2), 42 (109), 43 (75). This weakly differentiated but common species is known from the Cumberland River above the falls through Pulaski County, Ken- tucky and in springs and tributaries of the Cumberland River to Dickson County, Ten- nessee (23). The records presented here add to the distributional knowledge of the species and indicate that its populations appear to be sta- ble. Goniobasis (=Elimia) costifera (Haldeman 1841) Collecting Site.—44 (1). Goniobasis costifera has been considered as amore or less typical pleurocerid of Ohio River tributaries in Kentucky and Illinois (23). How- ever, the species does not seem to be abundant in Kentucky streams. The populational status of the species needs to be determined before any conservation recommendations can be suggested. We have a few specimens from the upper Kentucky River, where the species is rare. Goniobasis (=Elimia) laqueata (Say 1829) Collecting Sites. —24 (1), 27 (5), 28 (2), 43 (6), 45 (36), 46 (5), 47 (15), 48 (75), 49 (4), 50 (62), 51 (2). Some of us (4) previously reported speci- mens of G. laqueata from segments of the Cumberland River drainage, the eastern-most distribution of the species. This distinctive snail ranges west to Trace Creek (Tennessee River) in Humphreys County, and in the Duck and Elk rivers, Tennessee (27). In the upper Cum- berland River drainage, the species is fairly widespread but of sporadic occurrence. In western Kentucky (Green including Mud Riv- er, Cumberland including Red River, and Ten- nessee River) it is the most common species of Goniobasis encountered. To fluvialis (Say 1825) Collecting Sites.—None. A relatively large collection of mollusks from prehistoric Indian middens located near old Burnside, Pulaski County, Kentucky, removed before impoundment of Cumberland Lake, contain a number of large specimens of this peculiar species. This raises an interesting question. The modern distribution of Jo lies in the Tennessee River of western Virginia and eastern Tennessee, including the main tribu- taries Clinch, French Broad, Holston, Noli- chucky and Powell rivers (28). The nearest straight-line locality in which Jo can be found lies in the Powell River of Tennessee. The ques- tion is, did the Indians transport the specimens of Jo all the way from the Powell River or elsewhere to the Burnside area as food items— operculated snails such as this can live for hours or even days in cool weather out of water—or 66 Trans. KeENTucKY ACADEMY OF SCIENCE 48(3-4) for other uses? Or, was there at one time a population of Io in the Cumberland River that has become extinct in the interim? The ques- tion is, of course, partially rhetorical. However, the presence of the Io in the middens suggests that surveys of bank and/or old flood deposits should be undertaken to help answer this per- plexing question. Anculosa (=Leptoxis) praerosa (Say 1824) Collecting Site.—50 (41). Although this species has been reported from various sites in the Tennessee section of the Cumberland River, the record presented here from the Red River in Christian County is the farthest west it has been found in Kentucky. The most recent list of Kentucky endangered plants and animals (1) lists A. praerosa in Cat- egory 2, i.e., species up for possible status re- view by the U.S. Fish and Wildlife Service because their information “indicates that pro- posing to list as endangered or threatened is possibly appropriate, but for which conclusive data on biological vulnerability and threat are not currently available to support proposed rules.” Because our sample from Red River contains both young and reproductive adults, it seems probable that C2 is the appropriate category for the species in this very important population. Lithasia obovata (Say 1829) Collecting Sites.—51 (18), 52 (5). Lithasia obovata is the most widespread member of the genus in Kentucky. Six of the specimens from site 51 are morphologically similar to that termed forma sorida by Good- rich (22). Most populations of the snail in Ken- tucky appear to be healthy. Prehistoric Indians apparently used the species for food, along with Goniobasis curreyana and Pleurocera canaliculatum (29). Pleurocera acuta Rafinesque 1831 Collecting Sites. —57 (3), 58 (1). An attempt should be made to determine population sizes of this species. It probably de- serves a place on the Kentucky list as of special concern, at least at the C2 level on the federal list. Pleurocera alveare (Conrad 1834) Collecting Site.—59 (1). Pleurocera alveare is not at the present time under consideration for inclusion on the na- tional list of endangered species. However, the snail is very rare in Kentucky, and Sinclair (30) listed it as extirpated from the Tennessee River in Tennessee. The species should be listed as threatened in Kentucky waters. Pleurocera canaliculatum (Say 1821) Collecting Sites. —44 (2), 47 (9), 52 (1), 56 (7). Most populations of this large river snail ap- pear to be healthy. The snail is known to be resistant to several types of pollution, including moderate siltation (30). Pleurocera canaliculatum undulatum (Say 1829) Collecting Sites. —23 (88), 54 (2), 55 (1). Of the 88 specimens from Station 23, 50 were banded. This dimorphism has sometimes led to misidentifications but, as Goodrich (31) pointed out, banding is common in this variety in various streams, particularly in the Ken- tucky and Green rivers. Pleurocera curtum (Haldeman 1841) Collecting Sites.—60 (1), 61 (1). A highly variable species (32) known from headwater tributaries of the Tennessee and the main stream near Knoxville to Muscle Shoals, Alabama, and the Cumberland River above Burnside, Kentucky to the vicinity of Davidson County, Tennessee (also, the Caney Fork Riv- er, Tennessee) (23), P. curtum is not abundant in Kentucky. Some of us (4) reported small populations in the Rockcastle River in Laurel County and the Cumberland River in Mc- Creary County. Population assessments should be undertaken to determine the conservation status. Pleurocera cf. walkeri Goodrich 1928 Collecting Site.—62 (4). The characteristics of these 4 specimens fit the description of P. walkeri (32) better than those for any other described species. This species is known from the Cumberland River at Granville, Jackson County, Tennessee, the Little Sequatchie River near Marian, Tennes- AQUATIC SNAILS IN KeENTUCKY—Branson et al. 67 see, and from the Tennessee River at Muscle Shoals and Shoals Creek, Lauderdale County, Alabama. However, in the opinion of the first author, P. walkeri is probably conspecific with the variable P. curtum. LYMNAEIDAE There is divergence of opinion regarding generic designations in this family. Burch (14), for example, resurrected many of the genera of F. C. Baker (34), whereas Hubendick (33) considered these as subgenera. We follow the latter author. Lymnaea (Fossaria) humilis (Say 1822) Collecting Sites.—16 (2). Although there are few published records for this species in Kentucky (11 scattered rec- ords in the same number of counties) (16), it probably occurs throughout the state. Lymnaea (Pseudosuccinea) columella (Say 1817) Collecting Sites.—4 (5), 6 (1), 15 (1), 64 (1), 65 (5). This snail prefers quiet, vegetated back- waters over mud bottoms, where it sometimes produces prodigious populations. Statements of distribution within Kentucky are similar to those made for L. humilis. PHYSIDAE The Physidae is doubtless one of the most confusing taxa in North America, in spite of Te’s (35) valiant effort to bring order to the family. One of the reasons for confusion is the extreme variability within a nominal “species,” variability that reflects ecological plasticity. Te (35) recognized 4 genera: Physa Draparnaud 1801 with 2 northern species (P. jennessi Dall 1919 and P. skinneri Taylor 1954); Physella Haldeman 1843 (most species in the family, including all those known from Kentucky); the monotypic Aplexa Fleming 1830 (A. elongata (Say 1821)—outside our area); and Stenophysa Martens 1898 (2 species from northern South America, Central America, and Mexico, and introduced into Texas). These “genera” are most easily distinguished by features of the mantle. Physa (=Physella) gyrina (Say 1821) Collecting Sites.—1 (3), 67 (10), 68 (34), and 10 from Reelfoot Lake, Reelfoot National Wildlife Refuge, Tennessee. Several of the specimens from Station 1 ap- proach the morphology of P. gyrina ampul- lacea Gould 1855. This is a common species in western Kentucky, becoming progressively less common eastward. Physa (=Physella) heterostropha (Say 1817) Collecting Sites.—4 (3), 16 (2), 21 (4), 65 (8). Except in sections of the Purchase Area, P. heterostropha is the most widespread and common physid in Kentucky, occurring in vir- tually every kind of water, often to the exclu- sion of other species. ANCYLOPLANORBIDAE Although Burch (14) retained the Planor- bidae and the Ancylidae as separate families, Hubendick (36) and Stardbogatov (37) provid- ed compelling reasons why the 2 families should be combined, and we follow the latter authors. Their subfamily Rhodacmeinae includes the genus Rhodacmaea Walker 1917 which occurs in Kentucky. Laevapex Walker 1903 and Fer- rissia Walker 1903, both with Kentucky rep- resentatives, are placed in the subfamily Bu- lininae, which also includes Helisoma Swainson 1840. The subfamily Planorbinae includes Planorbula Haldeman 1840 (including Me- netus H. and A. Adams 1855 and Promenetus F. C. Baker 1935) and Gyraulus Charpentier 1837 (includes Armiger Hartmann 1840). In Burch’s (14) treatment, Promenetus and Me- netus are retained as separate genera and Heli- soma is divided into Helisoma and Planorbella Haldeman 1842. Gyraulus parvus (Say 1817) Collecting Site.—4 (5). There are very few records for this (and similar species) small (3-4 mm diameter) snail in Kentucky. Specimens are easily missed in general collecting. Fine-mesh dip nets and sieves should be used in searching aquatic vegetation and bottom debris. 68 TRANS. KENTUCKY ACADEMY OF SCIENCE 48(3-4) Gyraulus deflectus (Say 1824) Collecting Site.—16 (2). Previously unreported from Kentucky, this species is slightly larger than G. parvus. It tends to have an asymmetrical aperture, although it is not loop-shaped as in the last species. Like- wise, the body whorl is not evenly rounded or carinate. Our specimens were both 4.3 mm in diameter. Helisoma (Helisoma) anceps (Menke 1840) Collecting Sites. —16 (2). Also, 3 from Lau- rel Lake, Breaks Interstate Park, Virginia. Helisoma anceps frequents streams and running water as well as lakes, and it is much more common in such habitats than the next species, which prefers backwaters and lowland ponds, lakes, and sluggish streams. Helisoma (Planorbella) trivolvis (Say 1817) Collecting Sites.—1 (10), 16 (3), 64 (5), 68 (2), 69 (5), 70 (4), 71 (9), 72 (8). Menetus dilatatus (Gould 1841) Collecting Sites. —16 (2), 73 (1). Although widespread east of the Mississippi River (38), there are few published records for this species in Kentucky. The preferred habitat is in quiet, vegetated backwaters. Planorbula armigera (Say 1821) Collecting Site.—69 (A). This very distinctive little aquatic snail, re- cently reported from western Kentucky (11), is often mistaken for other small members of this family. There are white, tooth-like barriers a short distance within the aperture. Planor- bula jenksi (H. F. Carpenter), reported from Crane Pond Slough in Henderson County (10), is a synonym (14). Ferrissia fragilis (Tryon 1863) Collecting Sites. —74 (1), 75 (3). This small lentic snail has been reported from two Kentucky counties only (Jefferson, Madi- son) (16). The small size, cryptic coloration, and fragility are all factors causing it to be overlooked in general collecting. The species is doubtless of state-wide distribution. SPHAERIACEA This superfamily contains the familiar bi- valves generally called “fingernail” and “pea” clams (Sphaeriidae) and the introduced Asian clam of the Afro-Asian family Corbiculidae. Since Kentucky records for the sphaeriids are scanty, the following data are of interest. SPHAERIIDAE Pisidium casertanum (Poli 1791) Collecting Site.—16 (2). This small bivalve has not been previously reported from Kentucky (39). Sphaerium (Musculium) transversum (Say 1829) Collecting Sites. —4 (2), 64 (2), 68 (2). In spite of the relatively few records for Kentucky, this is a very common lentic species. Sphaerium simile (Say 1816) Collecting Site.—16 (2). Also with paltry Kentucky records, S. simile prefers sluggish streams and backwaters and ponds and lakes with abundant vegetation. Sphaerium striatinum (Lamarck 1818) Collecting Site.—65 (1). This is one of the most common lotic sphae- riids in the state, particularly in small- to me- dium-sized creeks and in shallow riffles of large rivers. Sphaerium rhomboideum (Say 1822) Collecting Site.—16 (2). This distinctive bivalve prefers sheltered, sluggish waters with vegetation (39). Sphaerium partumeium (Say 1822) Collecting Site.—1 (1). This species is retained in Musculium by Burch (38). It is common throughout the United States. CoRBICULIDAE Corbicula manilensis (Philippi 1844) Collecting Sites. —47 (3), 61 (12). Records from these sites have not been pub- lished previously, but this obnoxious clam is now very widespread in Kentucky waters. In many places it occurs to the exclusion of native sphaeriids. Whether there is a correlation re- mains to be determined. There are many un- published records for this species in the files of the Kentucky Nature Preserves Commis- sion.

Karan kA KSUCRS Plant and Soil Science Research, Kentucky State University, Frankfort, Kentucky 40601 ABSTRACT In vitro micropropagation of Paulownia tomentosa Steud. was achieved on a modified Murashige and Skoog’s medium. Nodal segments from mature (35-40-year-old) trees were used as explants to obtain shoots from axillary buds. Repeated multiplication from nodal segments of such shoots could be achieved. Rooted plantlets could be produced in about 6 weeks. These plants could be grown outside the culture tubes. The procedure described can be used for mass propagation of superior trees of P. tomentosa. INTRODUCTION The increasing demand for forest products makes sound management of forest resources a necessity. Such management practices in- clude reforestation to renew both timber as well as biomass resources. In many instances it is desirable to use propagules vegetatively derived from proven stock in order to ensure continued superior quality of forest resources (1, 2, 3). Vegetative propagation of mature forest trees from cuttings has not been possible for most species (1, 2, 4). Plant tissue culture technique has been suggested as a possible method for mass propagation of both conif- erous and hardwood tree species (1, 5, 6, 7). Many taxa of hardwood trees have been prop- agated in vitro with varying degrees of success (2). However, in most cases the starting ex- plants were derived from juvenile material (2). Only in a few instances have explants from mature trees been successfully used for plantlet regeneration in vitro (2, 8, 9, 10). The present work describes a tissue-culture procedure for micropropagation of Paulownia tomentosa Steud. (empress tree) from shoot segments of mature trees. P. tomentosa grows as a natu- ralized tree in many parts of the eastern and southeastern United States including Ken- tucky; it is valuable as a source of biomass and for reclamation of strip-mined land (11, 12, 13). Trees with superior form are a source of ' Any opinions, findings, conclusions, and/or recom- mendations expressed in this publication are those of the author and do not necessarily reflect the view of the United States Department of Agriculture, Cooperative State Re- search Service (USDA/CSRS).

The procedure de- scribed in this paper can be used for mass propagation of P. tomentosa trees with supe- rior growth characteristics. MATERIALS AND METHODS The experimental material was collected during the spring and summer of 1984 and 1985 from 35- to 40-year-old trees of P. to- mentosa growing in central Kentucky. The experimental material consisted of the top 15 to 20 cm segments from young (4 to 12 weeks after bud break) shoots of such trees. The shoot segments were wrapped in wet paper towels and brought to the laboratory. Within 1 hour of collection, shoots were cut into approxi- mately 3-cm-long pieces which were surface sterilized by treating them with a 2.265% so- dium hypochlorite (50% clorox) solution for 10 min followed by a 70% ethanol treatment for 2 min. Shoot segments were washed 4x with sterilized double distilled water. About 1-cm- long segments of stem containing 1 node, pieces of petiole, and leaves were put on medium C— a modified (14) Murashige and Skoog’s basal medium (MS) supplemented with 0.2 mg/liter a-naphthaleneacetic acid (NAA) and 2.0 mg/ liter benzyladenine (BA). For the study of the effects of auxin and cytokinin concentration on organogenesis, nodal segments of stems of 5- to 6-week-old plantlets which had devel- oped on medium C were inoculated on MS supplemented with 0, 0.02, 0.05, 0.1, 0.2, 0.5, 1.0, and 2.0 mg/liter NAA in combination with 0, 0.1, 0.2, 0.5, 1.0, 2.0, and 5.0 mg/liter BA. All media used in the present study were prepared with analytical grade reagents, con- tained 2% sucrose, 0.7% Difco bacto-agar and were sterilized by autoclaving at 1 kg/cm? pressure at 121°C for 15 min.

All cultures were grown on 10 ml medium in 25- x 150-mm culture tubes and were incu- bated at 25 + 1°C under continuous cool white fluorescent illumination of 450-500 »W /cm?. Ten to 20 cultures were grown on each me- dium. Weekly observations were made on the development of shoots from axillary buds, cal- lusing, and root differentiation for a period of 8 weeks after inoculation. Each experiment was repeated twice. RESULTS Response of Explants on Medium C Within 7 days after inoculation small shoots developed in both leaf axils and callus prolif- eration occurred at the cut basal end of stem axis. The 2 shoots which developed from the axillary buds grew equally well for some time, but in most instances 1 of the shoots became dominant 4-5 weeks after inoculation. Basal portions of the axillary shoots formed green, compact callus which differentiated into many shoots. Four to 6 weeks after inoculation root differentiation also occurred from the callus as well as the basal end of the original explant. Nodal explants from such plantlets were used for further experiments to study the effects of auxin and cytokinin concentration on organ- ogenesis. TABLE 2. Steud. cultures. Effects of Auxin and Cytokinin Concentration Shoot Development.—The effects of auxin and cytokinin concentration in the culture me- dium on shoot development have been sum- marized in Table 1. Shoot initiation from ax- illary buds and their subsequent growth was influenced by the BA and NAA concentrations in the media. On media containing 0.2 mg/ liter or more of NAA, shoot initiation was de- layed by 2 to 3 weeks. This effect could be partially overcome by the presence of 2 or 5 mg/liter BA. On media containing 1 or 2 mg/liter NAA only 10 to 40% of the cultures produced shoots which were poorly developed. Media contain- ing 1 mg/liter or higher concentration of BA and up to 0.2 mg/liter NAA induced growth of secondary branches which gave a bushy ap- pearance to the shoots. Secondary branching was inhibited by the presence of NAA in the medium. Frequently on media with 2 or 5 mg/ liter BA, shoot development also occurred from the callus produced from the basal part of new- ly developed shoots. Root Development.—Root development oc- curred either from the explant axis close to the developing axillary shoot or from the callus formed at the basal cut end of the explant axis.

Higher concentra- tion of NAA in absence of BA, and all con- centrations of BA in presence or absence of NAA delayed initiation of root development for up to 6 weeks after inoculation. Very high amounts of BA (2 or 5 mg/liter) in absence of NAA or in presence of 0.02 mg/liter NAA caused total inhibition of root formation. Data on root regeneration have been summarized in Table 2. Roots in cultures on media con- taining 1 mg/liter or higher amounts of BA were very thin, few in number, and often grew out of the culture medium. Callus Proliferation.—Callus proliferation occurred on all media except those containing 0-0.1 mg/liter NAA and no BA. All concen- trations of BA used, alone or in presence of NAA, induced callus proliferation. In most in- stances callus proliferated from the basal cut end of the explant axis but in presence of 1 mg/liter or higher amounts of BA callusing also occurred from the base of newly formed Fic. 2.

High concentrations (2 or 5 mg/liter) of BA also induced shoot differentiation from the callus tissue. Similarly high concentrations (1 or 2 mg/liter) of NAA caused root differ- entiation from callus in the absence of any shoot differentiation. Growth of Plantlets Outside the Culture Tube Plantlets produced on media containing 0.1, 0.2, or 0.5 mg/liter BA in combination with 0.02 or 0.05 mg/liter NAA were about 10 cm tall and had a well-developed root system about 6 weeks after inoculation (Fig. 1). These plant- lets were transplanted to a 1/1/1 vermiculite/ peat moss/potting soil mixture under high hu- midity under a glass bell jar. Gradually the humidity was decreased until the plants could grow outside the bell jar (Fig. 2). Discussion Thus far only a few in vitro studies on Pau- lownia tomentosa have been published (2, 10, 15, 16). In all instances except 1 (10) juvenile plants were used as explant source. While the 74 TRANS. KENTUCKY ACADEMY OF SCIENCE 48(3-4) present study was in progress, Burger et al. (10) published their studies on micropropa- gation of Paulownia. These authors used nodal segments collected either from flowering trees or from greenhouse-grown trees derived from cuttings of mature trees as explants. The de- velopment of axillary buds into shoots was achieved on a MS + BA + NAA medium. The elongated shoots were rooted on MS supple- mented with indolebutyric acid (IBA). The in- duction and development of axillary buds was easier on explants derived from greenhouse- grown trees compared to field-grown trees. In the present study the explants were derived from 35- to 40-year-old trees. The develop- ment of axillary buds into shoots occurred in only 10 to 15% of the cultures if the explants were taken directly from the mature field- grown trees. However, shoot development oc- curred in 100% of the cultures if explants were taken from plantlets developed on medium C. It seems that growth in vitro rejuvenates the explants from the mature trees. The present study, unlike that of Burger et al., describes a l1-step procedure for mass clonal propagation of Paulownia tomentosa where development of axillary shoots and rooting of these shoots can be achieved on the same medium. On MS + 0-0.05 mg/liter NAA + 0-0.5 mg/liter BA transplantable plantlets were obtained in 40-45 days after inoculation. Assuming | plan- tlet developing from each of the 5 nodal seg- ments (number of nodes varies between 5 and 7) in 45 days, 78,125 transplantable plantlets can be obtained from a single nodal segment after 1 year of multiplication in vitro. Doubts have been raised about the uniform- ity of tissue culture-derived plants because of the possibility of somaclonal variations within such plant populations (17). The procedure de- scribed in the present study minimizes the chances of somaclonal variations because of the absence of a dedifferentiation phase before the plantlet development. However, on certain media (for example medium C), the possibility of somaclonal variation does exist. On this me- dium, not only does the plantlet development take place from axillary buds on the explant but the callus formed from the cut end of ex- plant also differentiates to give rise toa number of plantlets. It seems possible that this phe- nomenon can be used to obtain plantlets from genetically engineered callus tissue. Once such plantlets with desirable characteristics have been obtained, their clonal mass propagation can be achieved by the procedure described in this paper.

Department of Biology, Western Kentucky University, Bowling Green, Kentucky 42101 ABSTRACT Indigenous microorganisms were stimulated to degrade hydrocarbon waste oils in a waste-water pond. The dominant organism isolated and identified from the pond was Acinetobacter calcoaceticus subsp. anitratus. Laboratory and field experiments on aeration and fertilization with 10 ppm garden fertilizer (10- 10-10) were conducted and the results evaluated by quantitative gravimetric analyses and gas chromato- graphic techniques to determine if oil degradation occurred. The biodegradation of this waste oil was considerably enhanced by the combination of forced aeration and fertilization as compared to controls. Gravimetric analyses of oil from laboratory ecosystems incubated 42 days at 25°C indicated that 38.2% more oil was degraded in the aerated and fertilized system than in the control system. Gas chromatographic analyses of oil from laboratory and field ecosystems showed quantitative decreases in individual hydrocarbon compounds associated with aeration and fertilization. INTRODUCTION In the early 1970s an aluminum die cast industry in southcentral Kentucky began dis- posing toxic waste products into a 1.0-acre, aboveground lagoon that was constructed on site. The waste products included chromium hydroxide, polychlorinated biphenols (PCB) and petroleum from in-plant processes. The lagoon is no longer receiving wastes but the Environmental Protection Agency and the Kentucky Department of Natural Protection are now requiring this facility to be recondi- tioned. The petroleum wastes were quite no- ticeable, and their removal could be monitored visibly by the disappearance of the abundant oily film. Since petroleum wastes have been in the lagoon for years, the probability is high that the indigenous flora has been enriched to utilize hydrocarbons because of its long ex- posure to them. Numerous reports in the lit- erature suggest that microorganisms metabo- lize petroleum (1, 2, 3). Several studies have been concerned with the biodegradation of hy- drocarbons by microorganisms in marine and estuarine waters (4, 5, 6, 7). Studies conducted on freshwater systems, however, are more lim- ited (8, 9, 10). Petroleum in freshwater seems to be de- graded mainly aerobically (1) and is temper- ature affected. Also, growth of the microor- ganisms may be limited by the amount of ! To whom correspondence should be addressed. 76 available nitrogen and/or phosphorus present in the aquatic habitat (1). This study was conducted to determine which petroleum-degrading microorganisms were in the petroleum-containing waste lagoon and if aeration and/or fertilization would en- hance their activity. MATERIALS AND METHODS Preliminary studies on the microbial com- munity of the lagoon were initiated 30 October 1985. Water samples were collected monthly in sterile dilution bottles from the same sample sites (Fig. 1) and their heterotrophic micro- organisms were enumerated on plates of Bush- nell-Haas medium containing 0.5% SAE 30 motor oil and Nobel agar (1.5% wt/vol) as the solidifying agent. The medium was sterilized by autoclaving for 15 min at 121°C, 1 atm. In order to assure adequate dispersal of the oil, the medium was prepared in small volumes (200 ml), tempered and swirled just before pouring it into plates. Control and oil agar plates were incubated in separate incubators at 25°C for 14 d (7). Triplicate plates were prepared for each enumeration. Counts on control plates were subtracted from counts on the oil agar plates, and the plate count esti- mates of hydrocarbon-degrading microorgan- isms were recorded as colony-forming units (CFU) per ml of water. A preliminary study was conducted to de- termine if hydrocarbon-degrading microor- ganisms were present in this pond. Represen- MicropiAL HypROCARBON DEGRADATION—Clauson and Elliott 77 Fic. 1.

Each pure culture was inoculated into 3 flasks of Bushnell- Haas broth containing 0.5% SAE 30 motor oil, incubated at 25°C along with 3 uninoculated controls for 14 d, then observed for oil deg- radation. The waste lagoon was separated into 2 parts by building an earthen dam. This provided a 50- xX 100-ft section to use as an experimental pond and the remainder as a control. The ex- perimental site, estimated to contain 700 kl of waste water and oil, was fertilized with 3.3, 50-lb bags of 10-10-10 garden fertilizer to ob- tain a 10-ppm nitrogen and phosphorus sup- plement. The fertilizer was broadcast over the entire surface of the experimental side (Fig. 2). Additional fertilizer was added as needed to maintain stable nitrogen and phosphorus levels. Aeration was provided with 2, 2-hp air pumps delivering 16 psi through a 3-inch pipe (Fig. 3). Water samples were collected period- ically and analyzed by the Water Quality Lab- oratory of Western Kentucky University to monitor the levels of nitrogen and phosphorus in the pond. Laboratory ecosystems were prepared by mixing a known amount of purified lagoon oil and 100 ml of lagoon water in each of 32, 250- ml sterile, cotton-plugged erlenmeyer flasks. The lagoon water was obtained from the con- trol portion of the lagoon and refrigerated until used. The purified lagoon oil was prepared Fic. 2.

The amount of purified lagoon oil in each eco- system was determined by adding approxi- mately 0.5 g oil to an oven-dried (2 h at 110°C), weighed flask, weighing the flask plus oil, then subtracting the weight of the flask from the weight of the flask plus oil. Eight of the flask ecosystems were used in testing each of 4 pa- rameters: no treatment, aeration by 200 rpm ona rotary shaker (New Brunswick Model V.5), fertilization with 10 ppm of 10-10-10 garden fertilizer, and aeration plus fertilization. Four of the flasks of each parameter were steam sterilized and used as controls. Our unpub- lished data indicate no loss of hydrocarbons occurred during drying or autoclaving. These data agree with Walker and Colwell (12). The flasks were incubated at 25°C for 28 and 42 d after which the oil was extracted and subjected to gravimetric and gas chromatographic anal- yses. Ten ml of hexane were introduced into Aeration of experimental pond. duplicate flasks of each parameter and mixed at 200 rpm on a rotary shaker (New Brunswick Model V.5) for 2 h. The hexane layer was sep- arated in a 250-ml separatory funnel and col- lected into appropriately numbered glass petri dishes that had been dried and weighed. The hexane was allowed to evaporate under a hood, the oil dried and weighed, and the percentage of decomposed hydrocarbons calculated. After the gravimetric calculations were completed, the oil from the laboratory ecosys- tem was analyzed by gas-liquid chromatog- raphy. A 20-mg sample of oil was collected from each petri dish and diluted with 0.1 ml hexane. A 10-ul GC syringe was used to remove 2 ul of the hexane extract which was then resolved on a glass column (6 feet by % inch by 2 mm) packed with 3% OV-1 on 80/100 Supelcoport from Supelco Laboratories. Gas chromatograms were obtained using a Varian Model 3700 gas chromatograph with an ion- flame detector and a Hewlett-Packard 3390A integrator. Parameters on the integrator were as follows: attenuation, 0; chart speed, 0.5; peak width, 0.4; threshold, 0; and area rejection, 0.

Enumeration of microbial populations from the pond with average monthly temperature. Symbols: O average monthly temperature, oil plate counts from control side of pond, A nonoil plate counts from control side of pond, Boil plate counts from experimental side of pond, Injections of 0.4 ul of hexane extract were made into the injection port set at 300°C and the ion- flame detector was set at 270°C. The chro- matograph was programmed for 160°C for 1 min, 8°C/min to 335°C, and 15 min isothermal at 335°C. Compounds in the eluted fractions were compared with gas chromatographic re- tention times of known alkanes and compared with the peak height response of these indi- vidual components. Gas chromatograph anal- yses were also performed on the oils obtained from the water from the control and experi- mental portions of the waste lagoons. RESULTS Since Roubal and Atlas (7) were able to plate count oil decomposers in a marine ecosystem, it was hypothesized that this technique would estimate hydrocarbon-utilizing microorgan- isms in limnetic ecosystems. Unfortunately, most of the counts on Bushnell-Haas agar were higher than counts on the Bushnell-Haas agar with oil. This indicated the oil was toxic to the microbial flora and an oligotrophic microbial population existed (13). Figure 4 depicts the waste lagoon plate counts and temperature over time. Plates counts were started on the waste lagoon before the dam was constructed. Counts on Bushnell-Haas agar without oil were highest in October (3.6 x 10°) before declining to 43 x 10° in January. On only 2 occasions were counts on the Bushnell- Haas oil agar higher than counts obtained on Bushnell-Haas agar without oil which is need- nonoil plate counts from experimental side of pond. ed to give a correct estimate of petroleum- degrading, aerobic, heterotrophic bacteria. Af- ter the dam was constructed, counts from the experimental side of the pond gave higher counts on the non-oil agar, thus no meaningful estimate of petroleum-degraders could be made. It was demonstrated, however, that this au- tochthonous population could be stimulated to degrade the petroleum pollutants by aeration and fertilization and oil decomposition deter- mined by gas chromatographic techniques. Observation of the changes in surface oil in- dicated changes in viscosity and brown zones of decomposed oil occurred in the experimen- tal portion as compared to little change in the control portion of the waste lagoon. Only 1 bacterial colony type was dominant in the oil agar plates and exhibited oil degradation in Bushnell-Haas broth with 0.5% SAE 30 motor oil present. These isolates produced zones of degradation after 14 d incubation at 25°C (Fig. 5). Characterization of these isolates was per- formed with the API 20E (Analytab products, Plainview, New York) and gave a profile num- ber of 000500203, which was a very good iden- tification for Acinetobacter calcoaceticus subsp. anitratus. This organism gave a typical distinct colonial growth on eosin-methylene blue agar as described by Spino and Geldreich (14). Quantitative gravimetric analysis on labo- ratory ecosystems also demonstrated that the microbial population may be stimulated to in- crease the amount of petroleum degradation 80 Trans.

Results obtained from both trials 1 and 2 indicate that biodegradation increased approximately equally upon fertilization or aeration. An even greater increase in biodeg- radation occurred when both aeration and fer- tilization of the systems was done.

Water samples that were collected for trial 2 analysis were exposed to commercial treatment procedures, which were ordered by the Kentucky Department of Natural Protection, and contained large quan- tities of pond sediment. Sludge and water re- moval possibly caused less oil degradation ob- tained in trial 2 (33.2%). Because the pond ecosystem was completely disturbed, the field study was terminated in March 1986. Gas chromatographic analysis of oil re- covered from the laboratory ecosystems also indicated that experimental flasks given aer- ation and fertilization showed a greater de- crease in individual hydrocarbon components than did their sterile controls (Fig. 6). Gas chro- matographic analyses of oils recovered from the waste lagoon (Fig. 7), showed that the oil was degraded more in the experimental por- tion than in the untreated portion of the la- goon. DISCUSSION Our results agreed with Roubal and Atlas (7) who found that the use of purified agar did not eliminate the problem of some organisms growing on control plates with no added car- bon sources. Possibly GELRITE could be used as an agar substitute to alleviate this problem (15).

Atlas (16) described a tech- nique that uses radiolabeled hexadecane-spiked crude oil to specifically enumerate petroleum- degrading microorganisms. This procedure is problematic since handling and disposing of radiolabeled compounds are problems and many laboratories could not be properly equipped to carry out such analyses. Only 1 colony type, which was always in dominant numbers on the oil agar plates, was isolated from the pond water and was able to biode- grade the waste oil. This suggests that this pond bacterium was indigenous. More oil degrada- tion occurred during warmer months but deg- radation also occurred at low temperatures which agrees with Lock et al. (9) who found 82 TRANS. KENTUCKY ACADEMY OF SCIENCE 48(3-4) =] Aa bed efghi i B Cc 1 5 10 15 20 25 RETENTION TIME (min) Fic. 7. Gas chromatographic analyses of oils recovered from the field study.

There have been other reports that Acine- tobacter can degrade petroleum. Walker and Colwell (12) reported that A. lwoffi degrades petroleum and produced long-chained n-al- kanes which was a waxy residue. Hauxhurst et al. (17) performed numerical taxonomic anal- yses on bacteria strains isolated from the Gulf of Alaska and 9 of them met the characteristics of the genus Acinetobacter and 6 decomposed pristane. A study by VanAken et al. (18) of the carbon sources that support bacterial growth in metal-working fluids used in large-scale in- dustrial operations demonstrated that 7 strains of Acinetobacter reached high densities with oleic acid as sole carbon source. The Acine- tobacter strains also grew in liquid culture on hexadecane, and naphthenic petroleum oils. Acinetobacter calcoaceticus RAG-1 (ATCC 31012) was found by Pines and Gutnick (19) to produce an emulsifying agent termed emul- san which allows the bacterium to grow in a petroleum-abundant environment. Chromatographic analyses of the field con- trol ecosystem revealed that weathering did not have much effect in reducing the concen- tration of hydrocarbons. Pond controls were not available to test the effect of aeration or fertilization on decomposition of the oil. Gas chromatographic analyses of oil from the ex- perimental portion of the waste lagoon dem- onstrated that the indigenous flora almost com- pletely decomposed the waste oil in the probable range of n-alkanes C,;—C,, and to a lesser extent degraded the waste oil in the probable range of n-alkanes C,,—Cy. Similar results were obtained by chromatographic analyses of the oil in laboratory ecosystems. One noted difference was that the field eco- system (Fig. 7) flora decomposed the waste oil more uniformly as indicated by the 2 large peaks (retention times 17.59 and 19.03) as com- pared to data obtained in the laboratory eco- system analyses. The laboratory ecosystems were incubated without controlled lighting in contrast to the field ecosystem which had nat- ural lighting. This would possibly stimulate al- gae to grow which did not grow in the labo- ratory ecosystems. Such algae may be involved in petroleum degradation. As the water tem- perature increased in the field ecosystem, algae (Oscillatoria and euglenoids) increased in numbers enough to be detectable by micro- scopic observation. Atlas (2) reviewed the ac- tion of microorganisms on petroleum hydro- carbons and recognized that cyanobacteria such as Oscillatoria spp. and algae were capable of hydrocarbon degradation. When conducting gravimetric analyses it was found, in order to get 100% recovery of the oil, the flasks containing the ecosystems should be washed with hexane twice when transfer- ring the oil to drying dishes. Drying the pond- recovered oil at 110°C did not cause volatiliza- tion of the hydrocarbons, as determined by gas chromatographic analysis. These analyses in- dicated that the initial peaks of this oil re- covered from the column were hydrocarbons in the probable range of n-alkanes C,;-Cy, which have boiling points greater than 270°C. Gravimetric and gas chromatographic anal- yses of waste oil from field and laboratory eco- systems have shown that aeration and fertil- ization can stimulate indigenous microbial communities to degrade contaminating hy- drocarbons. The combination of aeration and fertilization may be the logical and least ex- pensive method for removing contaminating hydrocarbons after oil spills in freshwater sys- tems.

JONES Department of Biological Sciences, Eastern Kentucky University, Richmond, Kentucky 40475 ABSTRACT A survey conducted during the academic year 1986-1987 provides information on herbarium collections in 19 herbaria in Kentucky. A total of about 212,000 vascular plant specimens and 5,400 nonvascular plant specimens is reported for the state. INTRODUCTION This survey is an update of the one published by Lassetter in 1978 (1), in which a total of 119,000 vascular plant specimens were re- ported from 12 herbaria. For the present study, a questionnaire was sent to all colleges, uni- versities, agencies, and individuals known to have herbaria in the state. The following data were requested: name and address of collec- tion, phone number, date of establishment, number of specimens, emphasis and special collections, names of curator and other staff, exchange policies, and loan policies. The ob- jective of the survey is to determine the current status of herbarium collections in Kentucky. The cooperation of all who responded to the survey is appreciated. RESULTS This survey provides information on 19 her- baria in the state. Fifteen are institutional, 3 are private individual collections, and 1 is a state government collection. The total number of mounted vascular plant specimens in these Kentucky herbaria is roughly 212,000. Collec- tions at the University of Kentucky (2 herbaria) and the University of Louisville account for about 96,000, while the number of specimens at the 5 regional universities is about 82,000. Collections at private colleges total about 10,000 with the great majority at Berea College. The total number of nonvascular plant specimens is about 5,400 with the largest collections at Centre College and the University of Ken- tucky. The information obtained in this survey is listed below. The acronyms (given in paren- theses after the institution) and general format of the data are based on Index Herbariorum (2). Proposed but unpublished acronyms are indicated by an asterisk.

In ad- dition to those listed by Lassetter (1), the fol- lowing herbaria also have considerable num- bers of Kentucky specimens: Austin Peay State University (APSC), Gray Herbarium of Har- vard University (GH), Missouri Botanical Gar- den (MO), New York Botanical Garden (NY), University of North Carolina (NCU), and Van- derbilt University (VDB). The total of 212,000 Kentucky herbarium specimens is an increase of 93,000 over the total of 119,000 in 1977 (the actual date of the survey). Because the UK College of Agricul- ture Herbarium was not listed in this previous survey, the actual increase in new collections is about 75,000 over the last decade, or about 7,000 specimens a year. Most surrounding states have collections that number several times these Kentucky totals. For example, in 1981, there were over 600,000 specimens in Tennessee her- baria, and over 1 million specimens were housed in Ohio herbaria (2). With the initiation of several new herbaria (Lindsey Wilson Col- lege and Cumberland College) and the in- creased activity at several others, these Ken- tucky numbers should rise sharply over the HERBARIA OF KENTUCKY— Jones 87 next few years. A number of county floras are currently in progress in the state, and this is very encouraging. Only 32 Kentucky counties have published floras, with 12 of these being done prior to the turn of the century, and only 9 completed since 1950 (3). The completion of additional county floras, especially from the neglected eastern and western regions of the state, is one of the best ways to increase our knowledge of the flora and vegetation of Ken- tucky.

MELHuISH, JR. U.S. Department of Agriculture, Forest Service, Northeastern Forest Experiment Station, Berea, Kentucky 40403 ABSTRACT The durability and resistance to decay of baldcypress wood have been attributed to the quantity and type of extractives in the wood. Studies of agricultural plants have linked variations in silicon content with the degree of resistance to herbivory and fungal attack. The data presented here show that baldcypress bark and wood contain higher concentrations of silicon than pine and oak. The durability of baldeypress wood as well as the ability of this tree to tolerate long periods of flooded soil may be related to this higher silicon content. INTRODUCTION Baldcypress (Taxodium distichum L. Rich.)—Taxodiaceae—wood is known for its durability and resistance to decay (1). This du- rability has been disputed and reported to be highly variable but has been historically at- tributed to the quantity and type of extractives in the wood (2). The durability of coastal red- wood (Sequoia sempervirens (D. Don) Endl), a member of the Taxodiaceae, has also been attributed to the type and quantity of extrac- tives (3). It has been suggested and debated that some tropical woods which exhibit resistance to ma- rine borers contain considerable quantities of silica (4, 5). Studies of agricultural plants have linked variations in silicon content with the degree of resistance to herbivory and fungal attack (6, 7, 8, 9). If the content of silicon in baldeypress wood is significantly higher than other tree species, it is logical to assume that variation in the silicon content as well as the extractives contribute to the natural resistance to decay and the variation in the durability reported for baldcypress wood. In addition, if the content of silicon is greater in baldcypress tissues, it may suggest that silicon accumula- tion is a mechanism related to the species sur- vival in its natural habitat. The most obvious difference in the natural habitat of baldcypress when compared with southern red oak and loblolly pine is that baldcypress is most com- monly found growing in flooded soils. Silicon accumulation by another wetland species, rice (Oryza sativa L.)—Poaceae—has been docu- mented (9). Wetland plants are adapted to flooded soils and the concomitant low oxygen conditions. 2 TRANS. KENTUCKY ACADEMY OF SCIENCE 49(1-2) Anaerobic conditions affect the bioavailability of nutrients and potentially toxic substances. Complexities exist but the net result of soil submergence is that it often enhances the avail- ability of manganese and iron to plants. As shown by Patrick and Delaune (10), the oxi- dized and reduced layers in a flooded soil can be characterized by a vertical distribution of the redox potential and concentrations of oxy- gen, nitrate, manganous manganese, ferrous iron, and sulfide depending on the degree of reduction. The findings of Okuda and Taka- hashi (11) suggest that the amount of silicon accumulation in rice plants promotes the oxi- dation power of rice roots resulting in the de- position of iron and manganese oxides on the root surface. Thus, silicon uptake by rice can reduce the probability of iron and manganese toxicity by decreasing the uptake of iron and manganese, Analysis of the leaves of baldcy- press and another wetland species, tupelo (Nyssa sp.), by Dickson (12) indicates that tu- pelo rapidly absorbs and tolerates high internal manganese concentrations while baldcypress apparently excludes manganese. Flooded soil conditions also increase the amount of silica in the soil solution and the uptake of silica by rice increases with increas- ing water content of the soil. Ponnamperuma (13) suggested that silica improves the oxygen supply to rice roots by increasing the volume and rigidity of the gas channels to the shoot and root. Elemental analysis was conducted on wood and bark samples from southern red oak (Quercus falcata Michx.)—Fagaceae, loblolly pine (Pinus taeda L.), and baldcypress as part of a pilot study for an air pollution study (14). The silicon content of the wood and bark of the 3 species is compared here. The trees sam- pled are growing adjacent to an abandoned smelter. Study Area.—Chrome Mining and Smelting Corporation (Chromasco) is located north of Memphis near Millington, Tennessee in the Illinois Central Woodstock Industrial Park (Fig. 1). The location of the oak, pine, and bald- cypress sampled with respect to the smelter is shown. Although the baldcypress trees are lo- cated upwind from the smelter it is assumed that they received smelter impact comparable to that of the oak and pine because of air in- version within the proximity to the smelter. Silicon dioxide was one of the documented emissions from the smelter (14). METHODS Sample Collection and Processing Two cores were chemically analyzed from each of 5 red oak trees, 7 loblolly pine trees, and 1 core from 4 baldcypress trees growing approximately 1.2 km from the abandoned smelter. Two bark samples were analyzed from each of 5 red oak trees, 7 loblolly pine trees, and 5 baldcypress trees. A teflon-coated Swedish increment borer was used to remove two 5-mm cores from each tree. The borer and extractor were rinsed with a 10% solution of quaternary ammonium chlo- ride in 2-heptanone and rinsed with acetone before insertion into the tree. This procedure removes any surface lead contamination (15). The cores were taken approximately 1.4 m from the ground on opposite sides of the tree. Studies of lead movement within xylem tissues suggest metal gradients may occur within the xylem making the standardization of sampling height advisable in comparative studies (16). Wooden plugs were inserted into the core holes to reduce the risk of fungal invasion (17). The cores were inserted into plastic straws, labeled and placed in plastic bags to prevent contam- ination in transport to the laboratory. Bark samples were removed with a stainless steel knife from the 2 core sites, placed in Ziploc plastic bags, and labeled. Field notes included date, tree species, tree location, tree diameter, and core location. Samples were processed immediately or fro- zen until surfaced to eliminate microbial growth and/or contamination as described by McLaughlin et al. (18) and Baes (19). Surfacing consisted of “peeling” the samples to reduce contamination and to reveal ring detail. Each specimen was examined under 10 magnifi- cation and the skeleton-plot technique of cross- dating was used to accurately date each growth ring as described by Stokes and Smiley (20). After the rings were measured the ring widths for each sample were plotted and checked for errors. The listing and plotting procedures of the Statistical Package for the Social Sciences (SPSS) were used. Ring widths are not usually directly com- parable between trees, e.g., the ring width for ao SILICON IN BALDCYPRESS AND PINES—Bowers and Melhuish 5% 8% 3% 12% 6% 16% Location of Shelby County in Tennessee. 7 | a i] pith weeeeee= eee mee eneng SHELBY COUNTY MEMPHIS —— i] 1 0 1 i] i) i] i] i] i] i] i] a ] i] 1 0 i] i 0 i] i] ‘] i] i] i] a 0 i] i] t 0 1] 1 a 1 i] 1 i] i] 0 1 i] i] 0 i] i] 0 i] 1] i] 1] 1] i] i] i] 1 H -1.3km ' eee ewww eee ene ee ee ee eee wee ee ee eres eee eee eee eee wen eeeeeecoceand Fic. 1.

The statistical significance of the difference measured among species is shown under the baldeypress mean 1960 may be much smaller on tree A than on tree B due to the advanced age of tree A. A trend line or growth curve was fitted to each ring-width graph so that the value for each year can be interpreted as percentage of growth. The percentages of growth derived by fitting the growth curve or indices have a mean approximating 1 for each sample. Indices are comparable among trees. If both trees A and B show reduced growth in a particular year, they both have an index value less than 1. The data are normalized by this curve fitting pro- cedure and are suited to analysis of variance (ANOVA) (22). The INDXA computer program, developed at the Laboratory of Tree-Ring Research, Uni- versity of Arizona, was used to convert the values into indices, to average the indices for each year of each sample to yield a site chro- nology, and to calculate the statistical param- eters of the site chronologies. Output from this program was checked with SPSS procedures. Each increment core was sectioned for chemical analysis into 5 segments: 1. pre- smelter years (1942-1952); 2. smelter years (1953-1970); 3. smelter-with-scrubber years (1971-1980); 4. post-smelter years (1981-1984); 5. eambium/bark. Chemical Analysis The samples were analyzed for 25 elements, including silicon, at the Northeastern Forest Experiment Station Research Laboratory in Berea, Kentucky. The wood samples were placed in a drying oven for 48 hours prior to grinding. Then a dried sample of 0.2 g was weighed, and heated for 1 hour at 200°C and at 600°C for 7 hours. The resulting ash was dissolved in 25 ml of 50% HCl. The HCI mix- ture was diluted to 50 ml with distilled water. The samples were analyzed with a Beckman Spectra Span 3B direct current plasma (DCP) emission spectrometer. Quality control sam- ples (EPA and National Bureau of Standards) were used to check the standards of all ele- ments before and after the wood samples were analyzed. RESULTS The mean concentration of silicon detected for the samples of all 3 species is shown in Table 1. The mean silicon concentration of the baldeypress samples was significantly higher than the mean for the loblolly pine and red oak samples for the smelter years, smelter-with- scrubber years, and for the bark samples. The ring-width indices chronology con- structed for each species of this study as well as an unimpacted upland loblolly pine and red oak site located approximately 125 miles south- east of the smelter is shown in Figure 2. All chronologies show a growth decline in 1968- 1969, 1977, and the drought of 1980 (Fig. 2). The most obvious difference in the chronolo- gies is the sharp increase in growth which oc- curs on the smelter-impacted loblolly pine site between 1981-1983.

DISCUSSION The silicon content of the baldcypress sam- ples was significantly higher than for the red oak and loblolly pine samples for 3 of the 5 time periods analyzed. The time periods in which no significant difference was found were the pre-smelter and the post-smelter periods (Table 1). The silicon content of the baldcy- press samples was not significantly greater for the post-smelter samples because of the high concentration for the loblolly pine samples. The loblolly pine samples of the post-smelter period contained a significantly higher silicon con- centration than any of the other loblolly pine wood samples (P = 0.01). The significantly higher concentration of sil- icon for the loblolly pine wood samples of the post-smelter period may be explained by the growth anomaly which occurred during this time period in the pine trees. Figure 2 shows the site chronologies for the smelter-impacted loblolly pine, red oak, and baldcypress sites of this study. Also shown in Figure 2 is an un- impacted oak-pine site chronology which can be used for a comparison of regional growth trends. The trees for this latter chronology are located approximately 125 miles southeast of the smelter. All the chronologies in Figure 2 show a growth decline in 1968-1969, 1977, and the drought of 1980. The most obvious differ- ence in the chronologies is the sharp increase in growth which occurs on the loblolly pine site between 1981-1983. This growth increase corresponds exactly with the post-smelter pe- riod but it is not believed to be attributable to the cessation of smelter activity. A holding pond was installed on the loblolly pine site in 1981 which had an irrigating effect on these trees during a period of regional drought causing increased silicon uptake. Tree-ring studies have shown that common growth trends occur throughout the eastern United States because of regional climate and that a reduction in tree growth is evident throughout the southeastern U.S. from 1977 through the 1980s (24, 25). All years of the chronologies showed growth below the 30-year growth mean (1953-1982) for the post-smelter period except on the impacted pine site. Although studies of agricultural plants have not shown that silicon affects growth rate (9), it is possible that growth rate affects the ac- cumulation rate of silicon. Therefore, silicon concentrations may not suppress or enhance growth, but rather growth rate affects accu- mulation of silicon. It is obvious that signifi- cantly greater concentrations of silicon were accumulated in the loblolly pine wood samples during a period of released growth (Table 1 and Fig. 2). Mariaux (26) suggests that the formation of silica grains in the wood of Ga- boon mahogany (Aucoumea_ klaineana Pierre)—Burseraceae of western Africa—is re- lated to growth rate. The other time period which did not reveal significantly higher concentrations of silicon for the baldcypress samples was the pre-smelt- er period. The younger age of the trees during this time period may partially explain the lack of difference between the species. According to Lewin and Reimann (9), studies have shown that silica content varies with age in some plants. Mature plants and older leaves have a higher silicon content. The loblolly pine and red oak samples did not show any trend which could be attributed to aging but the baldcy- press samples did show an increase in silicon concentration with time (Table 1). When the concentrations measured for all the wood samples, that is, pre-smelter, smelter, smelter-with-scrubber, and post-smelter are averaged together, the differences in elemental concentration due to differences in smelter ac- tivity and growth rates are pooled together. A significant difference was still obvious among species (Table 1). Although limited, the data reveal that bald- cypress bark and wood contain higher concen- trations of silicon than loblolly pine and red oak. The durability of baldcypress wood as well as the ability of this tree to tolerate long periods of flooded soil conditions may be re- lated to this higher silicon content. LITERATURE CITED 1.

Comments on habitat requirements and distribution are included, and search recommendations for 6 species not yet reported from Kentucky are presented. INTRODUCTION One of the most neglected segments of the Kentucky aquatic fauna is the sphaeriacean mollusks. Most generally, surveys of aquatic faunas either completely ignore these small clams or mention them by genus only. This hiatus is an unfortunate commentary on the status of our knowledge in the Commonwealth. Because of their well-developed mechanisms for passive dispersal and excellent adaptive features, sphaeriid clams are nearly cosmo- politan in distribution (1). In spite of that, the distribution patterns of these mollusks in Ken- tucky remain poorly understood, and some species—Pisidium dubium, for example (2)— have not been reported since early in the 1900s. Some species that almost certainly occur in Kentucky waters have not been reported at all. This dearth of information is entirely the result of inadequate collecting and/or proper iden- tification and reporting. Most of the information on sphaeriaceans in Kentucky has been reported in a few publi- cations. Bickel (3) summarized the literature through 1967, although Heard (4) implied the occurrence of several species that were not in- cluded in Bickel’s list, as did Herrington (5) and Burch (6). Since publication of the Bickel (3) checklist, several papers have discussed the distribution of various sphaeriacean clams in Kentucky, including the introduced Asian clam Corbicula (7, 8, 9, 10, 11, 12, 13, 14). Two families (Sphaeriidae and Corbiculidae), 3 genera (Sphaerium, Pisidium and Corbicula) and 13 species are presently known from the state. Another reason for the lack of published rec- ords for the Commonwealth is the dearth of easily accessible literature with special em- phasis on the Kentucky fauna. Thus, this paper presents a key, augmented by photographs of most species, in an attempt to stimulate more interest in this important segment of our aquat- ic fauna.

Populations of this noxious clam are sometimes enormous. Eupera cubensis is a coastal plains species that favors sluggish streams and ponds. This small, distinctive clam is often attached to moss, rootlets, and twigs in the water by means of byssal threads. It has not been reported from Kentucky but should be sought in Ballard, Hickman, Carlisle, Fulton, and adjacent coun- ties. Eupera singleyi Pilsbry 1889 is a synonym (5, 6). Sphaerium simile has been reported from Kentucky as S. sulcatum (Lamarck 1818) (3, 8), a synonym according to Burch (6). It was first reported from the Cumberland River drainage (2) in Kentucky but has in the interim been reported from the Tygarts Creek (7), Cumberland (8), Kentucky (9), Dix (10), Rough (13), and Licking (14) river drainages. The habitat is small lakes and backwaters of creeks and rivers with sand bottoms. Sphaerium striatinum is the most wide- spread fingernail clam in the state, from the westernmost streams (8, 13) to the easternmost (9). This is a stream species that occupies sandy to rocky riffles. It is the most abundant sphae- riid species in Salt River (19). Sphaerium fabale, only recently reported from Kentucky (9), enjoys a relatively wide distribution in the state (9, 10, 11, 13). The habitat is stream gravel, never fine sand or backwaters. Sphaerium transversum, one of the largest sphaeriids (up to 15 mm in length), is mostly a lowlands species in lakes, ponds, swamps, and backwaters of streams.

We (8, 9, 14) have found it common in the western half of Kentucky, less common in the east (9, 10, 11, 12, 13, 14), although Taylor (7) reported a thriving population in Tygart’s Creek. The preferred habitat is mud. Sphaerium partumeium has not been re- ported from Kentucky since 1900 (2). Thus, our record from Ballard County (14) was of interest. The habitat is nearly entirely in mud- bottomed lakes, ponds, and backwaters of streams. Sphaerium lacustre was implied by range in Kentucky (4), but the only record with exact locality data is from a small, heavily vegetated lake in Madison County (9). The preferred habitat is in the mud of ponds and lakes and, occasionally, in the backwaters of large streams (5). Sphaerium rhomboideum, another species preferring the mud of ponds and lakes and backwaters of streams (5), was reported from the Dix River drainage in 1981 (10), later (14) from a muddy backwater of Townsend Creek in Bourbon County (14). Sphaerium corneum, at present known only from Slate Creek in Bath County (9), is a Eu- ropean exotic of sporadic occurrence in the United States (5). It prefers soft, sandy mud in the backwaters of streams and ponds and lakes (5). Pisidiwm dubium has not been reported from Kentucky since 1900 (2), doubtless because of inadequate collecting. This is a very small (maximum length about 9.0 mm) species, al- though large for the genus. The habitat is mud in large, sluggish creeks. Pisidium casertanum was reported from the Ohio River at Louisville (18), and this re- mained the only record from the state until our recent report from Townsend Creek, Bour- bon County (14). The shell seldom measures larger than 4.0 mm in length and 3.3 mm in height, usually smaller. The species is adapt- able to many kinds of habitats (5), although it prefers mud-bottomed ponds and lakes. Pisidium variable is known from Buck Creek in Pulaski County (8), the only record for Kentucky. The preferred habitat is soft, silt mud in still water (5). Pisidium compression is known only from some mud-bottomed ponds in Madison County (9), although it doubtless is widely distributed in such environments elsewhere. An abun- dance of aquatic vegetation appears to be a habitat requirement. DISCUSSION AND SUGGESTIONS FOR FURTHER WoRK The relationships of the Kentucky sphaeriid fauna are mixed. Eupera (when found), of course, is a representative of the coastal plains fauna, being distributed from southern Texas to central North Carolina and Florida (4, 5, 6) and Oklahoma (20). The clam should be sought in waters of the Purchase Area. Pisidium is principally a northern complex of species; Sphaerium (ss) is most abundant in the Great Lakes region; the subgenus Musculium is prin- cipally southern (4). Thus, Kentucky must be thought of as an intergradation zone between 2 areas of speciation, and its fauna is a reflec- tion of that position, modified, perhaps, by var- ious phases of migration during Pleistocene times. At least 3 additional species ought to be sought in Kentucky waters. One is Sphaerium occidentale (Prime 1856). This species has been reported from all the states surrounding Ken- tucky (6); it lives in silt and mud in swamps, roadside ditches, and ponds with an abundance of decaying vegetation (5). Another species that should be sought is Sphaerium securis (Prime 1852), since it, too, has been reported from all surrounding states (6). The habitat is fine sand of ponds, lakes and rivers (5). Finally, Pisidium adamsi (Prime 1851), a rather large species (7 mm or more) that lives in muck and decaying vegetation of lakes, ponds, and the backwaters of rivers (5), has been reported from all the states surrounding Kentucky. Two additional species that may be in Kentucky are Pisidium nitidum Jenyns 1832 (practically transconti- nental) and P. punctatum Sterki 1895, known from Ohio, Pennsylvania, Virginia and Ten- nessee (6).

SIMON Large Rivers Larval Research Station, P.O. Box 727, Grayslake, Illinois 60030 ABSTRACT Specimens of larval to early juvenile Etheostoma smithi from Ferguson Creek, Kentucky, are described with emphasis on meristic, morphometric, and pigment characteristics. Adhesive eggs are attached to the underside of slab rocks in shallow upstream pools which are guarded by an attendant male. Egg diameters of E. smithi ranged from 1.9 mm to 2.4 mm. Larva hatched at 6.1 mm TL and possessed 15 preanal myomeres and between 19 and 21 postanal myomeres. Pigmentation of newly hatched larvae is limited to the mid-ventral yolk sac and mid-ventral postanal myosepta. Larvae have a large, spherical yolk sac, precocious fin-ray development, and yolk sac absorption after first fin-ray development similar to other larval Catonotus. INTRODUCTION The slabrock darter, Etheostoma smithi, is found sporadically in tributaries of the lower Cumberland River basin from the mouth of the river in Kentucky upstream to Caney Fork, Tennessee. It also occurs in the lower Tennes- see River below the Duck River (1, 2, 3). Information on larval fishes is limited within the tribe Etheostomatini. Larval and early ju- venile characteristics have been described for several species of the subgenus Catonotus, in- cluding E. flabellare, E. kennicotti, and E. squamiceps (4, 5, 6, 7); however, no meristic or morphometric information is available for larvae and early juveniles of E. smithi. Page and Burr (8), within the context of a life history study, provided information on early life his- tory stages, including egg incubation, larval development, and illustrations of a newly hatched larva, a 3-day-old larva, and an 8-day- old juvenile. The present paper describes larval and early juvenile characteristics with empha- sis on meristic, morphometric, and pigmen- tation features. Diagnostic characters will be evaluated for separation from sympatric species of Catonotus.

The reference collection of larvae was raised from aquarium-spawned adults from Fergu- son Creek, Livingston County, Kentucky (Cumberland River drainage). Adults were collected, acclimated, and induced to spawn, and eggs were incubated in enamel pans (9) at temperatures of 13°C and 21°C by the IIli- nois Natural History Survey. A total of 45 eggs and 105 larval and early juvenile slabrock darters were examined after preservation in 10% formalin. Preanal myo- meres included those anterior to a vertical line drawn from the posterior portion of the anus, while postanal myomere counts included a urostylar element. All myomeres were counted utilizing polarized light. After formation, fin rays were enumerated following methods in Hubbs and Lagler (10); methods of counting head canal pores followed Hubbs and Cannon (11). Morphometric characteristics were ex- pressed as per cent total length (TL) unless otherwise noted, and methods of measuring follow Simon (7). Specimens used for vertebral counts were initially preserved in 10% for- malin then transferred to isopropy! alcohol, cleared and stained using the method of Fritzsche and Johnson (12), and stored in glyc- erine. Illustrations were delineated following guidelines outlined in Faber and Gadd (13).

RESULTS Eggs Eggs were spherical, translucent, adhesive, and averaged 2.2 mm in diameter (8). In the present study, eggs from Ferguson Creek, Livy- ingston County, Kentucky, ranged from 1.9 mm to 2.4 mm (N = 45, ¥ = 2.2 mm). Mature eggs of the slabrock darter were spherical, de- mersal, and adhesive. Eggs contained trans- lucent yolk, a single oil globule, a narrow peri- vitelline space, an unsculptured chorion, and were unpigmented. Eggs were attached to the underside of slab rocks in shallow upstream pools (1, 8, 14, 15, 16). Larvae Morphology.—Characteristics of length and depth of slabrock darter larvae and early ju- veniles are presented in Table 1. The lengths at initial formation of selected structures are summarized. At 6.1 mm TL (newly hatched): well-developed pectoral fins with 9 incipient rays; yolk sac large, spherical (ca. 31.4% SL; 33.5% TL); yolk amber, with a single anterior oil globule, and distinct vitelline vein network; head not deflected over yolk sac; eyes oval.

DISCUSSION The habitat of E. smithi includes small creeks with bedrock slab pools in Ferguson Creek (8), gravel bottom pools in the Duck River, and variable habitat, usually pools with either sand, gravel, or bedrock substrate in the lower Cum- berland River (3). Reproductive behavior was previously studied in Ferguson Creek, Ken- tucky (8). Spawning occurs from late April to mid-June (3, 8), with greatest activity during May, when water temperatures ranged from 15 to 20°C (8). Adhesive eggs are attached to the underside of slab rocks, guarded by atten- IMMATURE SLABROCK DARTER IN KENTUCKY—Simon 19 Fic. 3. juvenile. dant male, in groups of only 1 or 2 eggs. Balon (17) classified fishes in this reproductive guild as speleophils (B.2.5), while Page (18) grouped known species of Catonotus as clusterers. Bal- on’s classification is based on adult spawning behavior, site of egg placement, and larval re- spiratory structures. Page based his classifica- tion on adult egg spawning site selection. Eggs incubated at 13°C hatched in 29.5-30.5 days, while eggs at 21°C hatched in 12.5-13.5 days (8). Larval and early juvenile food sources in- cluded chironomids and ephemeropterans, co- pepods, trichopterans, cladocerans, ostracods, and amphipods (8). Larvae are demersal, usu- ally remaining in close association with the substrate. Page and Burr (8) found age-0 E. smithi to occupy slab pools; however, many still were found in non-slab pools and slab rif- fles. Etheostoma smithi is sympatric with E. kennicotti and E. squamiceps throughout its range (15). Previous descriptions of larval and early juvenile E. kennicotti and E. squamiceps were available from Illinois tributaries of the Etheostoma smithi, slabrock darter, Ferguson Creek, Kentucky. a. 11.9 mm TL larva; b. 18.9 mm TL early Ohio River (6, 7). The separation of larval E. smithi from other sympatric Catonotus was facilitated since it possesses 15 preanal myo- meres, while E. kennicotti and E. squamiceps have 16 preanal myomeres. Postanal myomere counts in E. smithi were also higher ranging from 19 to 21 while E. kennicotti and E. squa- miceps range between 18 and 19. Newly hatched E. smithi were more sparsely pig- mented with melanophores limited to the mid- ventral yolk sac and mid-ventral postanal myosepta. Larvae of E. kennicotti can be dif- ferentiated by the more spherical, larger yolk sac and smaller head length/TL from E. squa- miceps. Etheostoma squamiceps has melano- phores distributed postanally, while E. ken- nicotti has melanophores limited primarily to the yolk sac (7). Larval characteristics of the subgenus Ca- tonotus, previously diagnosed by Simon (6, 7), were shared by E. smithi. Larvae possessed large, spherical yolk sacs (yolk sac length/SL = 0.32-0.42); well-developed pectoral fins; pre- cocious fin-ray development; and yolk sac ab- 20 Trans.

Ca- tonotus larvae also have either 15 or 16 preanal myomeres; a complex vitelline vein network on the ventral yolk sac; and a complete su- praorbital canal retrogressing to adult inter- rupted conditions during juvenile develop- ment.

Timmons Hancock Biological Station, Department of Biological Sciences, Murray State University, Murray, Kentucky 42071 ABSTRACT Twenty-seven species of fishes were collected from Murphy’s Pond from 1984 to 1986. Seven additional species have been reported from previous collections. The Kentucky distribution of 4 (Esox niger, Fundulus dispar, Lepomis marginatus, L. symmetricus) is restricted to extreme western Kentucky, and 1 (Ictalurus nebulosus) is poorly represented in state collections. Three species from Murphy’s Pond have been listed as threatened (Erimyzon sucetta) or endangered in Kentucky (Fundulus dispar, Lepomis marginatus). The greatest percentage of fish biomass in Murphy's Pond consisted of predators such as Amia calva, Esox niger, Micropterus salmoides, and catfishes (Ictalurus melas, I. natalis, I. nebulosus). Amia calva stomachs con- tained mostly crayfish, but also fish and amphibians, while those of Esox niger and Micropterus salmoides contained only fishes. INTRODUCTION Murphy’s Pond is a natural cypress swamp in western Kentucky that may have a species composition of fishes similar to that which it had when it was formed. Cypress swamps, like other wetlands, have disappeared in many areas in the past century. Despite their value as wild- life habitat and ability to retain flood waters and thus prevent downstream flooding, they have been drained and cleared for farmland. Even wetland areas designated as nature pre- serves, such as Murphy’s Pond, may be threat- ened by lowered water tables caused by chan- nelization projects outside the preserve. The objectives of this study were to deter- mine the species of fishes present in Murphy's Pond and their relative abundance. This is the first intensive survey of the fishes of Murphy's Pond. Past fish collections were made in Mur- phy’s Pond by Smith (1) as part of his survey of Obion Creek, and fishes were collected in 1980 by the Kentucky Department of Fish and Wildlife Resources with the fish toxicant ro- tenone (2). Two recent additions to the fish fauna of Kentucky were first found in Mur- phy’s Pond: Fundulus dispar, formerly con- sidered a subspecies of F. notti (3), and Le- pomis marginatus (4). Stupy AREA Murphy’s Pond is located adjacent to Obion Creek near the northeast corner of Hickman County in western Kentucky (Fig. 1). The pond and surrounding land was deeded to Murray 21 State University by the Nature Conservancy in 1975. A large area south and southwest of Murphy's Pond along Obion Creek is also swamp and was sampled during this study. Fish were collected in the adjacent beaver pond and Obion Creek since during floods they may be a source of fishes for Murphy’s Pond. Stream fishes may not stay or survive long in Murphy's Pond, but their presence in adjacent waters explains their occasional presence. The area sampled most frequently outside of Murphy’s Pond is referred to as the beaver pond, since beavers are active in the swamp and maintain a long dam. The beaver pond floods the region of the old Obion Creek channel. The beaver pond has a firm bottom that allows wading and seining, whereas Murphy’s Pond has a soft bot- tom that prevents effective seining. The chan- nelized section of Obion Creek west and south- west of Murphy's Pond was occasionally sampled. The channelized section is shallow (<1 m and often <0.3 m), narrow (4-5 m wide), with no riffles, few pools, and has a sand substrate. METHODS Fishes were collected from June 1984 to Au- gust 1986 using gill nets, seines, hoop nets, trotlines, and with the fish toxicant rotenone. Experimental gill nets with many different mesh sizes were used to sample as wide a va- riety of species and sizes as possible. Rotenone was used in 2 small areas (<0.01 hectare) of shallow water. Rotenone was difficult to use 22 TRANS.

Only small samples were desired from the pond in order to minimize the impact on the ecosystem. Hoop nets and trotlines were occasionally fished. Stomachs from piscivorous fishes were examined to de- tect prey species that were missed in other collections. Fishes were collected in Obion Creek by seining and in the beaver pond with the same methods described for Murphy’s creek Map of Murphy’s Pond and surrounding drainage. Pond. Fishes from all 3 areas were preserved and placed in the Murray State University Ich- thyological Collection at the Hancock Biolog- ical Station. Dissolved oxygen was measured monthly by Dr. C. D. Wilder, Director of Re- search in Murphy’s Pond. RESULTS AND DISCUSSION The fish species composition of Murphy’s Pond appeared to be typical of cypress swamps as described by Pflieger (5) for fishes in the FISHES IN WESTERN KENTUCKY—Timmons Lowland faunal region of the Mississippi River drainage. Twenty-seven species of fishes were collected in Murphy’s Pond from 1984 to 1986 (Table 1). Seven additional species have been reported from previous collections (1, 2, 3). Four of the species (Esox niger, Fundulus dis- par, Lepomis marginatus, and Lepomis sym- metricus) are restricted to extreme western Kentucky, and one (Ictalurus nebulosus) is poorly represented in collections in Kentucky (5). The most common fishes in Murphy's Pond were: Amia calva, Esox americanus, E. niger, Notemigonus crysoleucas, Ictalurus melas, Aphredoderus sayanus, Fundulus olivaceus, Gambusia affinis, Centrarchus macropterus, Elassoma zonatum, Lepomis gulosus, L. mac- rochirus, and L. symmetricus. The above list is not in order of relative abundance. Species diversity was lower than in a river drainage system because the pond is small, and the di- versity of habitats is low. Murphy's Pond was difficult to sample because the bottom in the shallow areas was extremely soft and made wading difficult and seining ineffective. The abundance of vegetation, including cypress trees and roots, provided cover for fishes when seining was attempted, and only allowed short seine hauls that were easily avoided by the fish. Gill nets and traps could be set in a few large, open pools, but much of the swamp was too thickly vegetated to set nets. Some pools filled with filamentous algae or macrophytes that impeded sampling during the summer. The greatest percentage of biomass of fishes in Murphy’s Pond was of predators such as Amia calva, Esox niger, Micropterus sal- moides, and catfishes (Ictalurus melas, I. na- talis, I. nebulosus). Stomachs from 15 Amia calva, which ranged in length and weight from 36 cm (0.4 kg) total length to 74 cm (3.6 kg), were examined for food items. Seventy-five per cent of the stomachs with food had cray- fish, 2 fish had Siren sp., and 3 had fish (Cen- trarchus macropterus and Ictalurus sp.) Stom- achs from 16 Esox niger, from 26 cm (0.2 kg) to 53 cm (1.2 kg), were examined. One-half the stomachs were empty, and the remainder had fishes (Erimyzon sp., Aphredoderus say- anus, Lepomis sp., L. gulosus, and Pomoxis sp.). Five examined largemouth bass stomachs contained crayfish, Aphredoderus sayanus, L. macrochirus, and L. symmetricus. Many species of fishes were less common bo [s) TaBLE 1.

A few species were represented by the collection of a single fish in Murphy’s Pond: Ictiobus cyprinellus, Minytrema melanops, and Le- pomis cyanellus. 24 TRANS. KENTUCKY ACADEMY OF SCIENCE 49(1-2) By late summer, some areas of Murphy's Pond had a dense covering of floating algae and oxygen was low (C. D. Wilder, pers. comm. ). In August, Cyprinus carpio collected in nets were in extremely poor condition with frayed fins. Poor water quality may limit the suitability of Murphy’s Pond as habitat for some species abundant in Obion Creek. Several species collected from Murphy’s Pond by earlier investigators were not found in this study. Fundulus dispar was collected in 1972 in a channel draining into Murphy’s Pond (3), but has not been collected again in Kentucky except near Reelfoot Lake (6). Smith (1) collected Dorosoma cepedianum and Le- pomis humilis in Murphy's Pond in 1968. McLemore (2) collected the grass carp (Cteno- pharyngodon idella), Notropis lutrensis, Ic- tiobus niger, and Micropterus punctulatus in 1980. The grass carp has been widely intro- duced in the southeastern United States to eliminate aquatic plants in farm ponds. No- tropis lutrensis and Micropterus punctulatus probably gained access from Obion Creek dur- ing high water and are not permanent resi- dents of Murphy’s Pond. McLemore also re- ported Erimyzon oblongus and Lepomis megalotis. Erimyzon oblongus may have been based on misidentified E. sucetta. I found E. sucetta in Murphy’s Pond. The Lepomis meg- alotis were either strays from Obion Creek, where they are common, or they were L. mar- ginatus, which is sometimes confused with L. megalotis. The species composition of the beaver pond was basically similar to that in Murphy’s Pond (Table 1). However, 4 species (Minytrema melanops, Ictalurus melas, I. nebulosus, Po- moxis annularis) were absent in collections from the beaver pond, but continued sampling probably would have yielded these species. None of the species taken by earlier collectors (absent in my collections from Murphy’s Pond) were present in the beaver pond. Fishes listed as the most common in Murphy's Pond were also representative of the most common species in the beaver pond. Fishes collected in Obion Creek adjacent to Murphy’s Pond and the beaver pond are listed in Table 1. Most species were common to abun- dant in collections except for Micropterus sal- moides and Etheostoma gracile. The most abundant species was Notropis lutrensis. Three species from Murphy’s Pond have been listed as threatened or endangered species (7). Warren et al. (7) consider Fundulus dispar and Lepomis marginatus as endangered, Er- imyzon sucetta as threatened. Fundulus dis- par was absent in my collections and has not been collected anywhere in Kentucky except Reelfoot Lake and one collection in Murphy’s Pond in 1972. Lepomis marginatus and Eri- myzon sucetta were common in the beaver pond, but difficult to collect in Murphy’s Pond because seining was ineffective. Branson et al. (8) in 1981 considered Lepisosteus oculatus and Lepomis marginatus as threatened species; Fundulus dispar, Elassoma zonatum, and Le- pomis symmetricus as species of special con- cern; and Erimyzon sucetta as undetermined. After a period of more thorough fish collecting in Kentucky, Lepisosteus oculatus, Elassoma zonatum, and Lepomis symmetricus were de- listed by Warren et al. (7). Elassoma zonatum and Lepomis symmetricus were abundant in the beaver pond and Murphy’s Pond. Three Lepisosteus oculatus were collected in the bea- ver pond and Murphy’s Pond. Murphy’s Pond is managed by Murray State University and the fish fauna receives little direct disturbance or perturbation. The great- est probable dangers to Murphy’s Pond are siltation and further channelization of Obion Creek. If Obion Creek is channelized deeper, the lower water table could lower significantly the level of Murphy’s Pond. Much of the pond is already shallow and a lowered water level would greatly reduce the surface area.

LEGG Community Research Service, Kentucky State University, Frankfort, Kentucky 40601 AND CHRISTIAN M. CHRISTENSEN Department of Entomology, University of Kentucky, Lexington, Kentucky 40546 ABSTRACT Comparisons were made among 8 samplers belonging to 4 experience groups to determine if shake-bucket estimates of larvae of the alfalfa weevil, Hypera postica (Gyllenhal), were influenced by intersampler variation. Although no significant difference was found in alfalfa stem lengths selected by the groups, inexperienced samplers selected stems with greater numbers of larvae. Overestimation of pest-population densities could result in management decision errors. INTRODUCTION After the realization in the 1950s that sole reliance on insecticides was not a viable insect- control strategy because of many unanticipat- ed problems, e.g., insect resistance, outbreaks of secondary pests, and pesticide residues, a push was made in the late 1960s for insect control via integrated pest management (IPM) (1). The development of sampling plans which provide accurate estimates of pest-population densities is a crucial step in the development of a successful IPM program. Although con- siderable research has been directed toward the construction of management-decision models, little attention has been focused on the problem of intersampler variability, which may lead to imprecise density estimates and deci- sion errors. An IPM program developed for the alfalfa weevil (AW), Hypera postica (Gyllenhal), is based upon the number of AW larvae per al- falfa stem found in samples taken by the shake- bucket technique (2). This technique consists of a sampler randomly selecting and removing stems while walking through the field and placing them in a plastic bucket. When the appropriate number of stems have been col- lected, they are shaken vigorously against the inside of the bucket and the dislodged larvae are counted. Although this technique is used primarily by inexperienced scouts to make management decisions as part of the alfalfa IPM program of many states, including Ken- tucky, little attention has been focused on the influence of intersampler variability on AW population density estimates. The objective of this study was to determine if intersampler variability existed in AW pop- ulation estimates based on shake-bucket sam- ples taken by samplers with varying levels of AW sampling experience. MATERIALS AND METHODS Sampling was conducted on 13 May 1987 at a degree-day accumulation since 1 January 1987 of 620 (base 48°F [8.9°C]). A 6-yr-old, 8-ha field of “Arc’ alfalfa was chosen for the experiment. The field was located in Anderson County, Kentucky, and had never been sprayed with an insecticide. Intersampler comparisons were made among 8 samplers belonging to 4 experience groups: 2 alfalfa growers with no scouting experience, 2 county extension agents with ca. 15 hours of in-field AW scouting experience, 1 recent graduate with a Ph.D. in entomology but no AW experience, and 3 professional entomol- ogists with extensive (4-12 yr) scouting expe- rience. Prior to sampling each grower com- pleted a questionnaire to document their experience scouting for AW larvae in alfalfa. Each sampler was given 5 large paper bags and instructed to walk through the field and randomly select a 6-stem sample from 5 dif- ferent 100-m* areas. The correct method of randomly selecting and picking a stem was SCOUTING FOR ALFALFA WEEVIL IN KeENtTucKY—Barney et al. 27 TaBLeE 1.

The bags were labelled by sampler, stapled, and returned to the laboratory for processing. This experiment was designed to evaluate in- tersampler variation in the stem picking pro- cess. The number of AW per 6-stem sample was determined and the length of 10 stems per sampler was measured. The second part of the experiment was de- signed to evaluate each sampler’s ability to recognize and count AW larvae in buckets af- ter a 6-stem sample had been taken. Six 6-stem samples were taken by one professional (R.J.B.) and the samples placed in numbered buckets. All samplers were shown how to identify AW larvae and distinguish them from spittlebug nymphs which were also very abundant at this time. Each sampler was then provided with a numbered score sheet and asked to examine each bucket independently and record their estimates of weevil numbers. The data from the pick-and-stem compar- isons were analyzed by one-way analysis of variance and the experience groupings were compared with planned nonorthogonal com- parisons. The data from the count test were analyzed by comparing each sampler to a des- ignated professional (R.J.B.) with a paired t-test. TaBLeE2.

Planned nonorthogonal com- parisons between experience group means showed that as the level of scouting experience increased the number of larvae per sample decreased (Table 1). Shufran (3) found that an inexperienced scout reported ca. twice as many AW larvae from shake-bucket samples as an experienced graduate student. This may in- dicate that inexperienced samplers tend to se- lect stems with more apparent feeding damage even though they were instructed to select stems randomly. The intersampler variation found in the picking test was not caused by a nonrandom selection of stems based on stem length. There was no significant difference (F = 1.61; df = 7, 72; P = 0.1444) in stem length measure- ments between samplers (Table 2). Shufran (3) also found no significant difference in stem lengths collected by 2 scouts. The results of the larval counting test showed that none of the samplers, regardless of their level of scouting experience, identified and counted AW larvae in buckets at a significantly different rate than the professional (Table 3). However, it must be pointed out that the av- erage number of larvae per bucket was less than 4 and that the larvae were mostly large fourth instars. A comparison of counts made earlier in the season when a greater number of larvae are smaller may reveal greater dif- ferences in count numbers between experience groups. Also, we believe that the ‘testing’ at- 28 TRANS. KENTUCKY ACADEMY OF SCIENCE 49(1-2) mosphere of this experiment would tend to make the samplers take more time and be more conscientious in their counting than a scout would be in an unsupervised situation. Assuming that the AW-density estimates made by the professionals and county agents were correct, the inexperienced samplers over- estimated the pest population density by a fac- tor of 2-3 times (Table 1). Significant overes- timations such as these can cause incorrect management decisions which result in unnec- essary applications of insecticides (4). This study illustrates the importance of intersampler vari- ation and the need for uniformity in sampling techniques.

While no indication of reduced caloric content was found, significant declines in total chlorophyll levels were detected in plants treated with regulated artificial rain of pH 3.5 and 2.5 under controlled laboratory conditions. INTRODUCTION Acid-rain formation from atmospheric pol- lutants, primarily particulate sulfates and ni- trates, has been shown to have a significant role in decline of productivity in numerous types of regional flora (1, 2). The relationship between specific compounds (SO,, NO,) re- leased due to anthropogenic activities and acid rain has been continually under debate (3) but it is evident that the phenomenon is not unique to the western hemisphere (4) and patterns of decreasing pH in the eastern United States have been well documented (5, 6). Notable studies on ecosystem response to acid rain have been done by Schofield (7), Tamm (8) and Knabe (9). Many species of plants, including Betula alleghaniensis Britt., Populus spp., Phaseolus vulgaris L., and Helianthus annuus L., have been subjected to acid-rain tests (10, 11, 12) since the potential for vegetation damage by acidic deposition (both wet and dry) was rec- ognized in the late 1960s. This study was designed to provide baseline data on the effect of acid rain on a geograph- ically widespread weedy species common to a variety of habitats. Xanthiwm strumarium L. (cocklebur) is a species that exploits disturbed habitats. A population from east central Texas was chosen to provide genomes that have had little exposure to acid rain conditions in recent years. Previous work (13) in our laboratory has shown that this species is a good laboratory tool particularly in regard to studies of chlorophyll levels. ‘Permanent home address: 117 Pine Village, Bards- town, Kentucky 40004. MATERIALS AND METHODS Fruits of cocklebur were collected in De- cember from Fannin County, Texas and ger- minated under constant light and alternating temperatures of 29-18°C (12 hr each temp.). Seedlings were transplanted to 10- x 10- x 9-cm plastic pots using a 3:1 peat perlite mix- ture and placed in growth chambers under the temperature regime mentioned above. Three different experiments were conducted using 2 different photoperiods: 16-hr light and 8-hr dark and 12-hr light and 12-hr dark period. Growth-chamber light intensity during the light periods was maintained at ca. 11,000 lux. The 12-hr temperature of 29°C in each 24-hr cycle was set to match or fit evenly within the light period of each experiment. Since this species is known to induce flowering under long dark periods, it was decided to expose plants under the longer dark cycles of 12 hr to the lower pH of 2.5 to determine if earlier stimulation of the flowering cycle would alter any response in chlorophyll and biomass development to the acidic treatment. The 3 different experiments involved spray- ing the foliage of 12 to 15 plants with solutions of pH values of 2.5, 3.5 and 4.5 using a me- chanical mister. The control of each experi- ment was of simulated rain of pH 5.6. Simu- lated rain solutions were prepared by standard titration with 18 M sulfuric acid to desired pH levels utilizing a Corning Model 21 pH meter. The misting applications were applied on an average of every third day providing total sim- ulated rainfall of between 123 and 175 mm but within each specific experiment all test and control plants received the same misting ex- posure within the limits of timing the misting applications. The total applications were de- 30 TRANS. KENTUCKY ACADEMY OF SCIENCE 49(1-2) TaBLe 1. Effect of acid-rain applications on biomass of Xanthium strumarium.

Hoagland’s solution was applied in equal amounts (ca. 50 ml)’ at regular intervals to each plant during the course of the growing period. To insure consistency in measuring chloro- phylls and to avoid possible chlorophyll dete- rioration from floral induction (and subsequent flower development) in the group of plants grown under the longer dark cycle of 12 hr, all 3 experiments were terminated at the same time. Previous experience in our laboratory had determined that actual floral bud devel- opment would be initiated in the Texas pop- ulation after 30 days of the 12-hr dark cycle. All plants were cropped at the cotyledon level for biomass measurements (g fresh wt.). Chlo- rophyll determinations used 5-g composite samples (in triplicate) from 3 plants in each test and control. Chlorophyll extraction, anal- ysis and calculations followed that outlined by Abdulrahman and Winstead (13). Six plants from the control set and group treated with simulated acid rain of pH 3.5 were analyzed for caloric content at the end of the growth and test period. The leaves of each of the plants after being air dried were ground in a Wiley Mill and 1 g samples combusted in a Parr bomb calorimeter to determine energy levels. RESULTS Pronounced effects on both biomass and chlorophyll levels were found in plants exposed to simulated acid rain applications. Plants ex- posed to simulated acid rains of pH 4.5, 3.5 and 2.5 had weight reductions of 27.6%, 25.2% and 21.8%, respectively, when compared to controls. Statistical analysis (Student’s t-test) showed all the reductions highly significant at the 0.1 level. Chlorophyll determinations from represen- tative plants of the experiments outlined in Table 1 showed similar patterns of chlorophyll reductions (Table 2). The pH treatments re- sulted in reduction of chlorophyll in all 3 ex- periments with statistically significant (at or near the 0.05 level) differences in plants treat- ed with simulated rainfall of pH 2.5 and 3.5. Percentage decreases of chlorophylls under the treatments of pH 4.5, 3.5 and 2.5 were 7.3, 8.7 and 8.7, respectively. The longer dark period of 12 hr did not seem to alter chlorophyll levels.

Caloric values of leaves were highly variable and there was no statistically significant difference seen when comparing the pH 3.5 test with the control. The control group had a range of 3.5 to 4.7 keal/g/dry wt. and the test plants were deter- mined to have a range of 3.2 to 4.7 kcal/g/ dry wt., and no further caloric measurements were made. Discussion The effects of simulated acid rain, at least on this species being investigated, indicates the potential for reduction of biomass by influ- encing the photosynthetic process. Primary productivity declines of 10% in natural eco- systems have been previously suggested to be the result of acidic precipitation (14) and in this study consistent reductions of biomass ex- ceeded 20% in the tests under 3 different ex- perimental acidic rain exposures. Accentuated differences between the control and experi- mental might be expected since the growth conditions were controlled providing the best possible habitat. In natural systems, maximum potential biomass production may be some- what reduced due to the fluctuations of lim- iting factors as water, temperature and light quality. The demonstrated reduction in chlo- rophyll levels under the 2 more acidic treat- ments indicates a possible mechanism of low- ered carbon fixation and indicates the need for further research to determine the actual phys- iological effects of acidic moisture on leaf tis- sue. Reductions in cuticular deposits on leaf surfaces by acidic solutions could result in de- creased chlorophyll production in nature since high light intensity will interfere with chlo- rophyll synthesis. Cytological investigations will be required to determine the actual mecha- nism(s) involved in reduction of photosyn- thetic pigments. The lack of statistically significant reduc- tions in caloric values of leaves was not un- expected since plant leaf material is comprised mostly of carbohydrate. The significant re- ductions in total biomass (if mostly carbohy- drate) would not show a caloric difference on a per-gram basis but a 20% reduction of total leaf biomass obviously would contribute to a significant reduction in total energy available ¢ when considering net productivity in a pop- ulation of primary producers. There has been significant public discussion about the effects of acidic deposition (both dry and wet) on biota in the eastern United States. Most of the Commonwealth of Kentucky now shows an annual average rainfall of pH of 4.2 or less (6). Power generating utilities and pub- lic officials have made numerous calls for more research prior to legislative controls on an- thropogenic activities that contribute to re- ductions in the pH of precipitation. It is hoped that the current study provides a contribution that documents a measure of the potential damage to biomass production resulting from exposure to precipitation acidic below the norm.

ELLIOTT Department of Biology, Western Kentucky University, Bowling Green, Kentucky 42101 AND ALAN R. COATES Country Oven Bakery, Bowling Green, Kentucky 42101 ABSTRACT Egg and milk products (26 egg and 6 milk) from various food processing companies were routinely screened for Salmonella spp. by FDA-recommended procedures. All 32 samples were determined to be negative for Salmonella but contained gram-negative, non-Salmonella bacteria which produced typical Salmonella reactions on selective differential agars. These bacteria were isolated and identified by morpho- logical and biochemical characteristics as Enterobacter cloacae, Citrobacter diversus-livenea (C. koseri) and Klebsiella pneumoniae. INTRODUCTION Food substances provide environments which are rich in nutrients and under proper con- ditions are suitable for microbial growth (1, 2). Consequently, food substances contaminated with pathogenic microorganisms are a serious concern for disease control and prevention (3, 4). In view of the federal regulations prohib- iting the occurrence of pathogenic organisms such as Salmonella in foods, the isolation of these organisms presents a difficult problem for the food scientist, since a high ratio of other bacteria compared to Salmonella spp. exists (5, 6). The Food and Drug Administration (FDA) has developed protocols for isolating and identifying Salmonella spp. These meth- ods generally include a pre-enrichment step that provides damaged organisms the oppor- tunity to repair physiological lesions and a se- lective enrichment step that allows the Sal- monella spp. to achieve numbers comparable to closely related non-pathogenic bacteria. Se- lective differential agars are used to determine biochemical and colony-form characteristics of Salmonella (5). In this laboratory, egg and milk samples rou- tinely tested for Salmonella were found to con- tain gram-negative, non-Salmonella bacteria which produced typical Salmonella reactions on media recommended by the FDA. Em- ploying biochemical and morphological tests, the characteristics and subsequent identifica- tion of these bacteria were determined. MATERIALS AND METHODS Materials.—Media employed for pre-en- richment, selective enrichment, selective plat- ing and biochemical screening were purchased from DIFCO Laboratories (Detroit, MI). The API 20 Enterobacteriaceae Identification Sys- tem (API 20E: Analytab Products, Plainview, NY) was employed for identification of the isolates. Samples.—A total of 32 samples (26 egg and 6 milk) obtained by the Country Oven Bakery (Bowling Green, KY) from various food pro- cessing companies was employed in this in- vestigation. The samples were screened for Salmonella spp. according to FDA-approved procedures (5). Media and Biochemical Tests.—Lactose broth was used for pre-enrichment, and tetra- thionate and selenite broths were used for se- lective enrichment. Bismuth sulfite (BS), hek- toen enteric (HE) and _ xylose lysine desoxycholate (XLD) agars were used for se- lective plating. Triple sugar iron (TSI) and ly- sine iron (LIA) agars were used for biochem- NON-SALMONELLA FROM EGG AND MILK Propucts—Bowles et al. 33 TaBLE l.

Isolation and Identification of Non-Sal- monella Species. —Typical salmonella-like colonies from selective differential media were transferred to the medium upon which the positive reaction was produced to reproduce the original results. The resulting growth was streaked for isolation on nutrient agar (NA) plates and incubated at 37°C for 24 + 2 hr. These isolates were identified by their cellular morphology, gram reaction, and biochemical characteristics using the API 20E system. RESULTS The 32 egg and milk samples were negative for Salmonella organisms. Typical Salmonella reactions were produced by non-Salmonella bacteria in 12 of the 32 samples (Table 1). Egg products (10 samples) were found to contain 83.3% of the non-Salmonella bacteria isolated and identified compared to the milk products tested; 38.5% of the egg samples contained bac- teria which expressed Salmonella-like charac- teristics when cultured on bismuth sulfite agar. No apparent differences in the occurrence of non-salmonella bacteria were found in the food products obtained from the different compa- nies. All typical Salmonella reactions were ob- served on BS agar. The selective enrichment broths tetrathionate and selenite did not inhibit the growth of these non-Salmonella organisms. Seven of the 12 typical reactions were attrib- uted to bacteria subcultured from selenite broth to BS agar, and 5 were subcultured from tetra- thionate broth to BS agar plates. Bacterial cultures exhibiting typical Sal- monella reactions were identified as Entero- bacter cloacae, Citrobacter diversus-levinea (C. koseri) (7), and Klebsiella pneumoniae (Table 2). Of the 12 samples producing typical Salmonella reactions, 92% were identified as E. cloacae. DISCUSSION The results of this investigation indicate that during various phases of processing, egg and milk products receive and/or retain gram-neg- ative, non-Salmonella bacteria which produce typical reactions on selective differential me- dia during routine screening for Salmonella organisms. These findings are significant in that typical Salmonella reactions by non-Salmo- nella organisms in various food products can increase the time required for screening. If the same types of egg and milk products from all commercial food suppliers harbor a similar percentage (37.5%) of bacteria capable of elic- iting a false-positive Salmonella reaction on BS agar, a significant waste of analytical time and supplies becomes a reasonable assumption. Furthermore, analysis of large numbers of food samples or samples requiring rapid-screening results can become cumbersome and difficult for food scientists. According to Sinell (8), microbial popula- tions found in food products are dependent upon the product composition and environ- 34 TRANS. KENTUCKY ACADEMY OF SCIENCE 49(1-2) TABLE 2.

Tetrathionate and selenite broths as selective enrichment media are effi- cient in growth enhancement of Salmonella. The results of this investigation indicate that these broths do not sufficiently inhibit non- Salmonella bacteria in the mixed microbial populations of the food products tested. Rhodes et al. (9) investigated the effect of incubation temperature on the growth kinetics and of se- lective enrichment broths for Salmonella en- richment. The selectivity of tetrathionate, sel- enite and Muller-Kauffman tetrathionate broths was increased at elevated temperatures (42°C). In recent years, many rapid microbial tests for Salmonella detection have been developed; however, the conventional method having FDA approval, used in this study, is widely em- ployed. To decrease the time required for Sal- monella detection (4-7 days) in the presence of bacteria such as those isolated in this study, the modification of existing tests (2) or devel- opment of more sensitive techniques (1, 10, 11, 12, 13) would be economically advantageous for food processing laboratories.

FRANKE Department of Mathematics, Statistics, and Computer Science, Eastern Kentucky University, Richmond, Kentucky 40475 ABSTRACT An example is given of a principal, prime, difference ideal which has no m-basis. INTRODUCTION The notation and terminology are as in (1, pp. 82-94). In particular, if R is a difference ring then R{x} is the difference ring generated by R and x, and if F is a difference field then F(x) is the difference field generated by F and x. If S is a subset of the difference ring R then [S] is the difference ideal generated by S and {S} is the perfect difference ideal generated by S. If T is a subset of R then T’ is the set of all elements products of powers of transforms of which are in T. If we define T(0) = T and T(n) =[T(n — 1)]' then {T} is the union of the ascending chain T(n). A basis for a set S in a difference ring R is a finite subset T of S such that {T} = {S}. T is an m-basis for $ if T(m) = {S}. The purpose of this paper is to exhibit a perfect difference ideal which has a basis but does not have an m-basis. This answers a ques- tion posed in (1, p. 94). It is shown that in this example the ring R is not a Ritt difference ring, i.e., R does not satisfy the ascending chain con- dition on perfect difference ideals. Therefore, it is still possible that every ideal in a Ritt difference ring has an m-basis. RESULTS Assume that C is a difference field with the identity transform. Define sequences x"), R"’, and F\ as follows. Choose x° and x,” alge- braically independent over C with x,'? = x. Define R° = C{x}, and F® = C(x). For i > 0, choose x“ transcendental over F’~) and define x‘) = (x®-) + x,"—-)/x®, Define RY = RO-Y {xO} FO = FO-Y (x) and RB as the union of the R". Since each x") satisfies the difference equation y. = y, each element of R satisfies that equation. Therefore, R\ is the ring ob- tained from C by the oridinary algebraic ring adjunction of the x" and x," for 0 Oand S6-) = T5- then x!—) € §0-1). Therefore, xx, € S0-), x9 € $0 and TW s S“). The proof of the converse inclusion uses a representation of the elements of R in a ca- nonical form. Define R = C[X, Y"] to be the polynomial ring over C in a double sequence of algebra- ically independent elements. Define R* to be the set of all Q € R with the following property. If i > 0 and M is a monomial of Q then M does not contain both X" and Y. Ifa €R, Q€ R* and a = Q(x", x,")) then Q is called a canonical expression of a. By repeated use of the relations x‘?x,") = (x°~) + x,"")), one may obtain a canonical expression for each element of R. Since x"? is transcendental over F"~!), it is easy to see that the expression is unique. If S° ¢ T° then S°~!" ¢ T" so there is an a ¢ T” with a € SS). Thus there are integers pand q so that a?a,? € S'~"). Choose the largest integer t with X“Y or Y. appearing effectively in the canonical expression of a. Consider the mapping o of R' into F'” defined by o(x) = o(x,) = O if i < j, a(x) = x9, a(x) = 0, a(x) = x) g(x, ) = [x"-) + a(x®—))] 4 ON) Ae Se We show that o is an algebraic specialization of R“ by proving that the restriction of o to R® is a specialization of R“ for 0 n then 0'™(x) = A(x) = 0), 0) preserves each relation x‘+!x, x,‘") + x") since both sides are mapped to zero when k =n and both sides are mapped to 2(2°j2) where p = (2§ — 1)/2* and q = 2"~-*-)) when k 0 on R* and 0 < a < b, then f(b) — (b — a)-f'(b) < f(a); also, (2) If f’ > 0 on R* and 0 < a < b, then I(f, a, b) < (b — a)-f(b), where R* denotes the set of positive real numbers and I(f, a, b) denotes the integral of f over the interval [a, b]. Special instances of (1) and (2) now yield sufficient (monotone and boundedness) conditions for [s,] to converge. Use (1) with f(t) = t™t!, a= 1 + 1/(n + 1), b = 1 + 1/n to establish monotonicity, and use a = 1, b= 1 + ‘én to establish boundedness. Similar applications of (2) with f(t) = t® also yield such sufficient conditions for the convergence of [s,,]. Profiles in Pascal: where does the time go? JOHN H. CRENSHAW, Department of Computer Science, Western Kentucky University, Bowling Green, KY 42101. Two major techniques for analyzing the computational complexity of algorithms are: (1) a priori analysis utilizing Big-0 notation and (2) profiling analysis in which run-time statistics are obtained from an implemented algorithm. A software package called PROFILE for the VAX 11/750 permits Pascal programs to be analyzed in a variety of ways. The primary analysis technique discussed provides the user with a table showing the names of all modules in a program along with a count of how many times each 59 module was executed. The execution of PROFILE is trans- parent to the user and leaves the user’s program un- changed. Using public domain software to debug PC assembler programs. VIRGINIA EATON, Department of Computer Science, Western Kentucky University, Bowling Green, KY 42101. FSDEBUG is public domain software that has certain advantages over the DEBUG program that comes with PCs and PC clones. For one thing, the FSDEBUG screen lets users see contents of memory, contents of registers, and flag settings all at once. A second advantage is that it lets users alternate between the FSDEBUG screen and another screen that lets them see the output of an executing program. A third advantage is that there are excellent HELP screens available from within FSDEBUG. I would recommend FSDEBUG to anyone who is learning PC as- sembler. Use of computers in medicine. SYLVIA CLARK PUL- LIAM, Department of Computer Science, Western Ken- tucky University, Bowling Green, KY 42101. Computer utilization in medicine falls into 4 main cat- egories: administration and record-keeping activities; high-tech, usually machine-related; clinical information services, using database or expert systems; and research, combining all techniques. Two fields using computers ex- tensively are radiology and clinical pathology. Radiology applications are usually machine-related, as Digital Image Processing. Pathology applications are usually more rec- ord-related, as monitoring abnormal results. Computers are also used to perform instant calculations, often in emer- gency medicine, pediatrics, and physicians’ offices, to de- termine dosage and assist in decision-making. A wide range of database services and expert systems is available for most medical specialties. Homotopy lifting. CARROLL G. WELLS, Department of Mathematics, Western Kentucky University, Bowling Green, KY 42101. A mapping p:E ~ B has homotopy lifting with respect to a space X if given mappings f:X x O — Eand F:X x I — B such that F(x, 0) = p(f(x)), x © X, there is a mapping G:X x I= Esuch that f(x, 0) = G(x, 0), x © X, and p(G(x, t)) = F(x, t), (x, t) © X x I, Homotopy lifting with respect to the Cantor set (HLP/C) and to a sequence with 1 limit point (HLP/S) are studied. It is proven that a mapping has HLP/C if and only if it has HLP/C locally. Also mappings with HLP/C will have HLP/S and mappings with HLP/S will have HLP with respect to a point. PSYCHOLOGY Variables influencing adolescents’ perceptions of tele- vision violence. M. SHANNON MACKIE,* MARIA S. MCLEAN, and JOHN W. PORTER, Department of Psy- chology, Thomas More College, Crestview Hills, KY 41017. 60 TRANS. KENTUCKY ACADEMY OF SCIENCE 49(1-2) Twenty pre-delinquent adolescent subjects judged car- toon and crime drama scenes to be more violent as harm to the victims in the scenes increased. They judged cartoons to be more frightening and more personally disturbing as harm increased. There was a tendency for scenes to be rated as more humorous when subjects viewed scenes in a group than when alone, There was no relationship be- tween personality, as measured by the Eysenck Personality Questionnaire, and the subjects’ ratings. It is suggested that violence, even in fantasy settings, should be carefully mon- itored. The group effects observed were attributed to a diffusion of subjects’ attention away from the violence in the scences. These results do not support previous research that suggests that personality variables are strongly cor- related with perceptions of television violence. SCIENCE EDUCATION Teaching chemistry by closed-circuit television—per- sonal observations. DAVID R. HARTMAN, Department of Chemistry, Western Kentucky University, Bowling Green, KY 42101. “Biochemistry for the Health Sciences” was taught by closed-circuit television to a group of nursing and dietetics students in Owensboro and on campus in Bowling Green, simultaneously. Television production equipment and teaching techniques were examined. Student response to this unique experience was favorable. ZOOLOGY & ENTOMOLOGY Aggressive behavior in the Cumberland Plateau sala- mander, Plethodon kentucki. DONNA L. DELPONT* and PAUL V. CUPP, JR., Department of Biological Sci- ences, Eastern Kentucky University, Richmond, KY 40475. Aggressive behavior in defense of areas by means of direct attacks and threat displays was observed in male and female Plethodon kentucki. All intruders (N = 96) immediately began exploring when introduced into a res- ident’s chamber. Threat displays used by residents to deter intruders (60.4%, N = 58) included: orientation (97.9%, N = 94), partial head-raise (49.0%, N = 49), full head- raise (51.0%, N = 49), open-mouth display (35.2%, N = 19), and snapping (9.3%, N = 5). Contact occurred in 38 trials (39.6%), 19 (50%) resulting in aggressive encounters involving a biting/chasing/fleeing sequence. All contacts made by intruding males (44.7%, N = 17) resulted in aggressive encounters with residents always being the vic- tor. Such behavior suggests that male and female P. ken- tucki may be territorial. An equilibrium model of protistan colonization in bar- ren aquatic systems. PAUL V. MCCORMICK, Depart- ment of Biology, University of Louisville, Louisville, KY 40292. This research investigated the utility of equilibrium is- land theory in explaining patterns of protist colonization in isolated aquatic systems. There was no relationship be- tween species richness and the rate of immigration, al- though a strong positive correlation with extinction was found. There was evidence of non-monotonicity in rate functions over time. Although a dynamic equilibrium ap- peared to be achieved within 8 wk, there were fluctuations around this level that could not be explained by changes in environmental parameters. Discrepancies between these results and theory may be explained by: (1) initially in- hospitable conditions resulting in a lag in immigration, (2) decreases in microbial species richness below equilibrium levels as a result of predation by mosquito larvae, and (3) increases in microbial species richness above equilibrium levels following passive dispersal of colonists by mammals.

While both species assumed the body position characteristic of oxygen uptake at the water surface, the depletion of atmospheric oxygen within a respirometer was greater for F. catenatus, suggesting a more efficient mode of surface breathing under conditions of hypoxia. The survival times of both species were enhanced with access to atmosphere. Different strategies for coping with hypoxic conditions in the 2 species are apparent. The northern studfish maintains aerobic metabolic capacity through efficient aquatic surface respiration while the common shiner may increase anaerobic metabolism under conditions of hypoxia. Both species possess the requisite physio- logical capacities for survival in headwater stream systems subject to intermittent flow regimes. INTRODUCTION In freshwater environments, headwater streams offer the opportunity to assess the range of adaptive responses to fluctuations in the physicochemical environment. The capacity of an organism to adapt to such fluctuations, especially in temperature and oxygen avail- ability, will determine its ability to become an integral component of headwater ecosystems. Species that dominate headwater communities that experience environmental fluctuation, however, may be less successful in more stable, more diverse downstream ecosystems where the intensity of biotic interactions is greater (1, 2). Thompson and Hunt (3) were the first to suggest that fishes inhabiting headwater streams subject to intermittency of flow demonstrated greater tolerance to fluctuations in the physi- cochemical environment than species inhab- iting more stable and environmentally uniform 69 downstream areas. This has been experimen- tally verified in the comparison of tolerances to changes in temperature, pH, and dissolved oxygen of headwater inhabiting versus main- stream inhabiting individuals of the same species of cyprinids and etheostomatines (4). During late summer and early fall, large concentrations of fishes, chiefly cyprinids, often are trapped in standing pools in the headwaters of the North Rolling Fork River in central Ken- tucky. Here, the possibility exists for the rapid depletion of dissolved oxygen with uncertain opportunities for replenishment before critical levels are experienced. The purpose of this study is to compare the oxygen uptake patterns of 2 species of stream dwelling fishes: the com- mon shiner (Notropis chrysocephalus) and the northern studfish (Fundulus catenatus). A common behavioral response of fishes exposed to hypoxic conditions is to move to the surface and breathe the thin film of richly oxygenated 70 TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3-4) water at the surface. The role of aquatic sur- face respiration in facilitating the uptake of oxygen has been studied, especially in tropical species routinely exposed to hypoxic conditions (5, 6, 7, 8, 9). The role of aquatic surface res- piration as an adaptation to the physicochem- ical conditions characteristic of headwaters was assessed for the two species mentioned above. THE STuDY AREA The 2 subject species of this study were col- lected from second order headwater streams (10) of the North Rolling Fork River in western Boyle County, Kentucky. The fishes of the North Rolling Fork constitute the most diverse ichthyofaunal community within the Salt Riv- er Drainage of central Kentucky (11). Mod- erate alkalinity, medium hard to hard water of generally good quality, a substratum of non-calcareous shales and limestone, and a cir- cumneutral pH are all characteristics of this drainage (11). The fishes were collected from shallow (<0.5 m) pools with copious leaf litter and muddy bottoms and from the margins of small riffles. MATERIALS AND METHODS Fishes were collected during early autumn using a backpack electroshocker and trans- ported in plastic buckets to the laboratory where they were acclimated in well-aerated water in aquaria for at least 10 days prior to experi- mentation. A constant photoperiod of 12 hr light: 12 hr dark was maintained. In order to determine oxygen consumption rates and critical dissolved oxygen levels with- out access to an overlying atmospheric layer, individual fishes, ranging in weight from 2.93 to 6.45 g (N. chrysocephalus) and 1.62 to 3.12 g (F. catenatus) were placed in 300 ml B.O.D. bottles and subjected to gentle aeration for at least 4 hr to enable acclimation of the fish to its surroundings. Initial measurements of dis- solved oxygen were made using an oxygen probe (Extech #8012) connected to a pH/mv meter (Cole-Parmer #5984-00). This probe is designed for use with B.O.D. bottles as it min- imizes atmospheric exchange during measure- ments and can be left in the B.O.D. bottles between measurements. Bottles were sealed and held in a water bath maintained at 25°C. Hour- ly measurements of dissolved oxygen were made until critical levels, determined as the point of cessation of opercular beating, were reached. At this time, individuals were re- moved and wet weights determined. This pro- cedure was repeated 5 times for each species for a total of 10 trials. This technique has prov- en useful in other studies of small fish metab- olism (12). In order to assess the impact of availability of atmospheric oxygen, a respirometer was constructed using a glass jar 12.0 cm long with a diameter of 7.5 cm. The cap for the jar was fitted with the oxygen probe used in the pre- vious procedure. Another oxygen probe (YSI #54) was fitted through the cap such that it was positioned in an air space of 175 ml volume that overlaid the 300 ml volume of water with- in the respirometer. This enabled simultaneous measurement of dissolved oxygen, measured as mg 1-] and atmospheric oxygen, measured as percent of atmospheric composition and converted to g 1-1. A pH probe was also fitted such that changes in pH accompanying oxygen uptake and carbon dioxide release could also be monitored. This procedure, using the res- pirometer and fitted probes, was again re- peated 5 times for each species for a total of 10 trials. RESULTS Patterns of oxygen utilization, measured by comparison of depletion rates of atmospheric oxygen vs. dissolved oxygen, suggest different strategies of adaptation to oxygen deficient waters for F. catenatus and N. chrysocephalus. Survival times for both species increased dra- matically with access to atmospheric oxygen (Table 1). Decreased oxygen consumption rates were recorded as dissolved oxygen diminished (Figs. 1, 2). As aquatic oxygen consumption rates declined, differences were observed in the rate of utilization of atmospheric oxygen (Figs. 1, 2). After approximately 22 hr, a sharp decline in atmospheric oxygen was recorded in the respirometer containing F. catenatus indicating a relatively rapid removal of oxygen from the atmospheric compartment. Decreases in dissolved oxygen resulted in both species assuming a posture in which aquatic surface respiration (ASR) would be facilitated. Fun- dulus appeared to be more efficient at this activity as it acquired a posture much like that observed by Lewis (9) for poeciliids and fun- SURFACE RESPIRATION IN KENTUCKY FisHes—Barton and Elkins Tall TABLE 1. headwater stream fishes.

In the 2 species stud- ied here, different modes of adaptation to headwater environments are evident. Cyprinid species that inhabit shallow streams have been demonstrated to effectively opti- mize their combined temperature/dissolved oxygen requirements in order to balance aero- bic metabolic needs with ambient oxygen (13). Members of the family Cyprinidae are effec- tive also at switching to anaerobic pathways under conditions of oxygen deprivation (14, 15, 16). The results of this study suggest that N. chrysocephalus may shift to increased an- aerobic metabolism under prolonged condi- tions of diminished oxygen availability. The levels of atmospheric oxygen in the respiro- meter did not exhibit as pronounced a decline for N. chrysocephalus, suggesting a decreased oxygen requirement with time for this species. Studies on lactate accumulation under hypoxic conditions would substantiate the role of an- aerobic metabolism suggested by this investi- gation. Lewis (9) postulated that the small, up- turned mouth and the dorso-ventrally flattened head of fundulid and poeciliid fishes optimize their capacity for ASR. Laboratory studies of microhabitat selection have revealed that Poe- cilia reticulata (family Poeciliidae) chose shal- low areas of an experimental aquarium that were closest to the air-water interface (17). Our study verified Lewis’ observations that cypri- nid species assume a greater inclination of body axis while engaging in ASR and that the body form of fundulids best accommodates this ac- tivity. This study further substantiates the ob- servations by several researchers that cyprin- odontiform fishes are the best adapted headwater species in terms of capacity for ASR (7, 8, 9). While our study appears to attribute the survival capacity of F. catenatus in oxygen deficient waters to an enhanced capacity for ASR, N. chrysocephalus appears equally SURFACE RESPIRATION IN KENTUCKY FisHes—Barton and Elkins 73 adapted to these conditions because of its en- hanced anaerobic capabilities. Surface dwell- ing species that engage in ASR may be sub- jected to greater risk of avian predation (18). Enhanced anaerobic capacity would enable optimization of metabolic scope in the face of physicochemical fluctuation yet avoid the po- tential liabilities of surface confinement during periods of oxygen deprivation.

JOHN DaILeEy, JAY CRAIG, AND KATHY WELBORN Department of Biology, University of Southern Indiana, Evansville, Indiana 47712 ABSTRACT A stand of bald cypress, Taxodium distichum (L.) Richard, in Hovey Lake, Posey County, Indiana was sampled for age, growth and reproductive characteristics. This stand is located in the Hovey Lake Fish and Wildlife Area and is one of the northernmost in the middle of the T. distichum east-west range. Thirty- three 25-m? sample plots were established and 359 trees measured for DBH. Fifty-seven specimens were cored for age determination. Mean DBH for all trees was 251.4 + SE 36.1 mm and trees between 101 and 400 mm DBH were most frequently encountered. We counted 114 trees in the 201-300 mm size class, making it the largest class. The smallest tree measured 30 mm DBH and the largest 1,240 mm DBH. The mean DBH of cored trees was 183.6 + SE 13.6 mm, mean age 56.5 + SE 3.5 yr and mean growth rate 3.25 + SE 0.83 mm/yr. Mean growth rate for cored trees increased from 2.84 + SE 0.16 mm/yr in 0-100 mm DBH trees to 3.86 + SE 1.39 mm/yr in 401-500 mm DBH size class trees. Based upon regression analysis of data from cored trees, the average age of all trees was 74.8 + SE 7.5 yr. The age of most specimens was between 50 and 100 yr. Large numbers of 0-100 mm size class were not observed, but germination and seedling growth are still occurring along some of the lake’s margin. INTRODUCTION The bald cypress, Taxodium distichum (L.) Richard, reaches its northernmost limit of dis- tribution in the middle of its east-west range in southern Illinois, western Kentucky and southern Indiana. Many isolated stands of this tree have been lost in these areas due to habitat modification caused by wetlands draining, silt- ation and pollution. One stand, which has not been lost, is located in the extreme southwest- ern corner of Indiana in Hovey Lake, on the Hovey Lake Fish and Wildlife Area, Posey County, Indiana. Taxodium distichum is most successful in regions with fluctuating water levels. It pro- duces seeds that apparently must germinate on ground which is very moist but not submerged (1). The seedlings must then reach a height greater than the next sustained high water if they are to become established (2). It has been demonstrated (3) that seedlings can survive submergence for several weeks, but will not grow during that time. High seed production 1 Present address and reprint requests: Department of Biology and Life Sciences, Box 20483, Savannah State Col- lege, Savannah, Georgia 31404. 74 seems to occur in 3-year cycles (1) and must coincide with high water which will allow seeds to soak for 1-3 months for best germination. An absence of reproduction has been noted in swampy areas which are silted-in even though mature trees are still growing there (1). Hovey Lake was formed about 500 years ago as a large oxbow of the Ohio River, and it is presently contained within Hovey Lake Fish and Wildlife Area in Posey County, In- diana (4). Originally, the maximum depth of the lake was about 12.3 m, but siltation grad- ually reduced this value to approximately 1.2 m and the surface area was reduced to about 120 ha. In 1975 the Uniontown Navigation Locks and Dam was completed and the project, by increasing the mean depth of the Ohio River, backed an additional 2.2 m of water into the lake basin. At present, Hovey Lake has a max- imum depth of approximately 3.4 m and a surface area of about 560 ha. It retains a nar- row connection with the Ohio River and its level is therefore dependent upon the mean pool of the river. Despite its geographic location, Hovey Lake, like other areas of the lower Ohio River valley, exhibits a flora and fauna with distinct south- BaLpD Cypress IN INDIANA—Kozel et al. 73 DOA N WNW s Lr’|AV \ S \ NY . . oe ‘ e .

Only 2 previous studies of T. distichum in Hovey Lake (5, 6) are known to the authors. This study was undertaken to determine the present status of the bald cypress (no distinc- tion between varieties and/or sub-species of T. distichum was attempted here) in Hovey Lake. Such baseline studies are necessary in ecolog- ically important sites now subject to environ- mental modification. MATERIALS AND METHODS Aerial maps of Hovey Lake were used to locate areas containing living Taxodium dis- tichum. Grids were drawn on these maps, as- signed numbers, and 33 sample points were selected at random for study. The points were then located on the lake and 25-m? sample plots established by tagging “corner” trees (Fig. 1). Within each plot the diameter (DBH) of every bald cypress was measured to the nearest mm using a diameter tape. An age-estimate of all trees measured was made as follows. One or 2 specimens were selected at random from each plot (total = 57 trees) and their ages were directly determined by coring and counting rings. Increment borers were used to obtain samples of trees up to 500 76 TABLE 1. Trans.

Whole cores (cork to past the pith) were used to calculate growth rates. Two cores were taken 180° apart and then averaged. Since all of the sampling was done from canoes on partially submerged trees, cores and DBH measurements were made | m above the water line. Most trees were submerged in water ap- proximately 1 m deep. Core preparation and age-determination methods were adapted from standard methods (7). Cores were mounted in clear epoxy resin, sectioned, lightly sanded, rubbed with a small amount of vegetable oil to make the rings more visible and examined by means of a 30 dissecting microscope. Linear regression analysis was then used to demonstrate the relationship between age and DBH and to provide a method for estimating the age of trees greater than 500-mm DBH. Trees were grouped into 100-mm DBH size classes and values for the following parameters in each calculated: numbers of individuals; density (no./m/?); relative density; % frequen- cy; relative frequency; mean DBH (in mm); mean age (in yr); and mean growth (in mm/ yr).

The mean DBH was 251.4 + SE 36.1 mm. Trees with a DBH between 101 and 400 mm were the most fre- quently encountered. Their densities were also greatest. One hundred fourteen trees were measured in the 201-300 mm size class, mak- ing it the largest size class. Size classes greater than 400 mm were poorly represented, but 36 individuals were found in the 0-100 mm size class. The smallest tree measured was 30 mm DBH, and the largest 1,240 mm DBH (neither was cored). Trees from which cores were taken were also arrayed into 100 mm size classes (Table 2). The mean DBH of all cored trees was 183.6 + SE 13.6 mm. Based upon direct counts of growth rings from these cores the mean age in years and mean growth rate in mm/yr were estimated. The mean age and growth rate of all cored trees was 56.5 + SE 3.5 yr and 3.25 + SE 0.83 mm/yr, respectively. The mean age of trees from the largest size class (401-500 TaBLE 2.

The mean growth rate of trees 0-100 mm DBH was 2.84 + SE 0.16 mm/yr and this rate appeared to increase gradually to 3.86 + SE 1.39 mm/yr in the 401-500 mm size class. The small num- ber of trees sampled in the 2 largest size classes should be noted. It should also be noted that the mean growth rates are estimates of all years of tree life, and are not present growth rates. The relationship between DBH and age for T. distichum was determined by linear regres- sion analysis of the cored trees (Fig. 2). Curvilinear regression produced a slightly higher R value (0.978), but it is believed that the number of large trees which seem to be responsible for the deviation from linearity is not great enough to warrant this equation’s use. The linear regression model was extended to allow the age of larger (DBH) trees to be estimated. Using this model, the age of the 1,240 mm DBH tree was estimated to be ap- proximately 325 yr. DISCUSSION The average age of all measured trees, de- termined using the regression equation, was 74.8 + SE 7.5 yr. The difference of 18.3 yr between all specimens and cored trees is prob- ably due to the inclusion of 24 trees over 500 mm DBH in the former group. The ages of most T. distichum studied were between 50 and 100 yr. The germination time of these trees is therefore placed approximately between the years 1880 and 1930. This interval was before the principal periods of levee and dam con- struction along and on the Ohio River. Such construction has the effect of reducing water level fluctuations along the river and in Hovey Lake. Since fluctuating water levels seem to be necessary for the establishment of successful stands of T. distichum, it is not surprising that the smallest size class was not strongly repre- sented in our samples. Sherrod et al. (8) thought that the placement of flood control dams on the Savannah River might inhibit T. distichum establishment in South Carolina. Cain (5) seems to support, and provide back- ground for, the present observations of size class distribution in Hovey Lake. He noticed a”... general absence of cypress reproduction and hence development in stands where ma- ture trees are now dominant ...” in his 1932 78 Trans. KENTUCKY ACADEMY OF SCIENCE 49(3-4) EST report, and suggested that recently completed agricultural levees might be restricting the rise and fall of water in the lake. When we checked for cypress reproduction in our sample plots no measured tree repro- duction was found. A few seedlings less than 20 cm high were seen along short stretches of shoreline, indicating that reproduction and germination are still occurring. Cain (5) found seedlings abundant only at the lake outlet, an area not sampled in the present study. Munson (6) did not mention seedling germination or saplings in his report, but Spitznagle, the Prop- erty Manager at Hovey Lake Fish and Wildlife Area (pers. comm.) has seen both seedlings and saplings along the perimeter of the lake’s east- ern side. He stated that they are found in dense willow stands which suggests that they must be shade tolerant. Others feel that willows will competitively exclude cypress (8, 9) and that the latter are understory intolerant (10). Spitznagle (pers. comm.) believes that silt deposition, which has been very high in recent years, provides conditions for T. distichum re- t E pA t iw : 3 i ik usa Z i tis 4 Fic. 3.

This siltation may be compensating for the lack of water level fluctuation in some parts of the lake and allowing germination to occur. The effects of siltation on mature trees are less clear. Approximately one-half the lake shore is enclosed by a ring of dead bald cypress (Fig. 3). The exact cause of their demise is uncertain, but their presence is noted because of their large numbers. The mean growth rate of 3.25 + SE 0.83 mm/yr is slightly higher than that reported by Mitsch and Ewel (11) for two cypress domes in Florida receiving treated sewage and hard groundwater (2.8-3.0 mm/yr). It is lower than that found by Langdon (12) in Louisiana (4.6- 5.3 mm/yr). Schlesinger (13) indicated that as cypress stands mature the above-water pro- duction per tree increases. Our data showing an increase in growth rate with increasing age and size support this conclusion. The relatively low numbers of small diam- eter size class T. distichum and the limited population size of seedlings noted here, and by BALD Cypress IN INDIANA—Kozel et al. 79 others, indicates the need for further study of these trees in habitats with artificially restrict- ed water level fluctuations.

BARNEY Community Research Service Program, Kentucky State University, Frankfort, Kentucky 40601 AND J. C. Parr AND B. C. Pass Department of Entomology, University of Kentucky, Lexington, Kentucky 40546-0091 ABSTRACT Carbofuran granules were applied at planting to determine whether this systemic insecticide would increase seedling establishment, growth and yield of alfalfa. Spring plantings were made in the field under no-tillage conditions and in the greenhouse under simulated no-tillage and conventional-tillage conditions. In the field, alfalfa measurements were often greater in treated plots but results were inconsistent and not correlated with carbofuran rate. Pests and predators were largely unaffected. In the greenhouse, the high rate of carbofuran increased stem height and yield under simulated no-tillage but not conventional-tillage conditions. INTRODUCTION Establishment of alfalfa, using conservation- tillage methods, is increasing in the southern and eastern United States. Some extension per- sonnel have included an application of car- bofuran, a carbamate insecticide, into their recommendations for planting under the as- sumption that it is necessary to control the pests which may be present in damaging numbers under reduced tillage conditions. Carbofuran has been reported to stimulate growth in tobacco (1), corn (2), soybeans (3), and alfalfa (4). One mechanism to explain growth differences in plants treated with car- bofuran is a response to reduced feeding pres- sure by insects. Increased yields following re- peated carbofuran (10G) treatments have been found in alfalfa (5) and ladino clover (6). Each study attributed this increase to less root injury by the clover root curculio (CRC), Sitona his- pidulus (F.). However, in a laboratory study (7), dry-weight reductions of leaves, stems, and top growth (=yield) were not significantly cor- related with numbers of CRC. Another hypothesis is that the insecticide or its metabolites function as growth stimulants within the plant. Enhanced growth and yield of burley tobacco treated with carbofuran has been attributed to an unknown physiological response of the plants to the insecticide (1). 80 Our study was done to determine if the ap- plication of carbofuran at planting would in- crease seedling establishment, growth, and ul- timately yield of alfalfa. The study was conducted in 2 parts: in the presence of pests in the field (1985 and 1986) under no-tillage conditions and in the absence of pests in the greenhouse (1985) under simulated no-tillage and conventional-tillage conditions. MATERIALS AND METHODS Field.—Field experiments were conducted at the Spindletop Research Farm, Kentucky Agricultural Experiment Station, Lexington. Glyphosate herbicide was applied at the rate of 2.5 kg (AI)/ha on 10 April 1985 to a 0.14- ha area of a 5-yr-old alfalfa stand and on 30 April 1986 to an adjacent 0.07-ha area of the same stand to kill existing vegetation. Sixteen plots in 1985 (7.3 by 12.2 m) and 1986 (4.9 by 9.1 m) were established in a randomized com- plete block design (RCBD). Carbofuran gran- ules were broadcast at 0, 1.1, 2.2, and 4.4 kg (AI)/ha on 6 May 1985 and 7 May 1986. ‘Buf- falo’ alfalfa was no-till planted later the same day at the rate of 16.8 kg of seed per ha each year. Alfalfa stem length and density were mon- itored in a 0.09-m? area randomly chosen in each plot. Stem densities were measured dur- No-TiLtL ALFALFA ESTABLISHMENT—Barney et al. 81 ing seedling establishment and _ periodically until harvest. Yield was evaluated by harvest- ing a 4.1-m? area (0.9 by 4.5 m strip) of alfalfa in each plot on 23 July and 3 September 1985 and an 8.2-m? area (0.9 by 9.1 m strip) on 4 August and 7 October 1986. Harvest dates were delayed in 1986 due to the lack of rainfall in June (2.2 cm) and the slower growth of alfalfa. The strip samples were weighed in the field and a subsample was removed and sorted into alfalfa and weed components. Subsamples were weighed, oven dried for 24 hr at 80°C, and the dry weight yield of alfalfa in each sample was determined. Pests and Predators.—Insects active on the soil surface were monitored weekly in each plot with a pitfall trap (8) from 14 May to 2 September 1985. Foliar-inhabiting insects were monitored with a sweep net (38.1 cm diam) by taking 15 sweeps per plot weekly from 4 June to 2 September 1985. Two emergence traps (30 cm*) were in- stalled in each plot on 21 May 1985 and 15 May 1986 to sample the emerging adult CRC. Cages were removed at first harvest, and the foliage and soil vacuumed with a suction sam- pler. Four cages were also placed in the old alfalfa surrounding the plots in 1985 and 1986 to estimate the existing CRC populations. In addition, 2 uncaged areas per plot (0.09 m7?) were vacuumed with a suction sampler on 29 May 1986 to collect CRC adults. Greenhouse.—Conventional-tillage plant- ing conditions were simulated in the green- house in 1985 by adding unsterilized soil (be- neath non-legume sod) from the research farm to plastic flats (30 by 60 by 3 cm). “Apollo IT alfalfa was planted in the flats at the field rates. The same rates of carbofuran granules used in the field were broadcast on the flats and then covered with soil (2 cm). Treatments were rep- licated 4 times. No-tillage planting conditions were simu- lated in the greenhouse by filling flats with non- leguminous sod cut from the research farm. Paraquat herbicide was applied on 6 June at the rate of 1.1 kg (AI)/ha to kill the sod. The same carbofuran rates as used in the field were applied on 10 June 1985. Two furrows (2-3 cm deep and 10 cm apart) were cut lengthwise in the dead sod within the flats. “Apollo IP alfalfa seed was planted in the furrows. Treat- ments were replicated 4 times. The 32 flats were arranged on 4 tables ina RCBD and were watered and hand-weeded as needed. Alfalfa stem length was monitored by ran- domly measuring 5 stems/flat each week. Stem density was monitored periodically by count- ing the number of stems in a designated 234- cm? area/flat. All stems were harvested 36 and 60 days after planting and yields calculated. The data were subjected to analysis of vari- ance and the means separated with Duncan's multiple range test (9) (P = 0.05) with the general linear models procedure of the statis- tical analysis system (10). RESULTS Field.—The application of carbofuran gran- ules at planting under no-tillage conditions had a positive effect on alfalfa stem length. Alfalfa stems from plots receiving the high rate of carbofuran in 1985 and all rates in 1986 were significantly longer than alfalfa in untreated plots at the first harvest (Table 1). This effect was reduced by the second harvest. Carbofuran had no effect on alfalfa seedling establishment or survival in 1985, but had a significant effect in 1986 (Table 1). Stem den- sities were much lower overall in 1986 than in 1985, probably because seedlings succumbed to the lack of soil moisture in June 1986. The increased stem length found at the high carbofuran rate in 1985 did not produce sig- nificantly greater dry weight yields at either harvest (Table 1). However, the increased stem lengths and stem densities found in carbofuran treated plots in 1986 did result in increased yields, although not in proportion to the car- bofuran rates applied. Yields were not signif- icantly different at the delayed second harvest in 1986 due to the large variability between replications. Variability in 1986 was caused by extremely dry weather and a broadleaf weed problem which resulted in a poor, spotty al- falfa stand. Pests and Predators.—CRC adults were much more abundant in 1986 than in 1985. Only one adult CRC was found in 32 emer- gence traps in 1985. Emergence of CRC from cages during the first cutting period of 1986 was not reduced in carbofuran treated plots (Table 2). Vacuum sampling in uncaged areas on 29 May 1986 revealed significant reductions in catches of adult CRC in plots treated with the highest rates of carbofuran. However, 4 82 Trans.

This suggests that the overall CRC population was reduced in the treatment area, irrespective of treatment. Sweep-net sampling for pests with the po- tential to damage alfalfa seedlings revealed no significant differences between populations of CRC or the potato leafhopper, Empoasca fabae (Harris), in carbofuran treated and un- treated plots. The most abundant predaceous insects in sweep samples were damsel bugs (Hemiptera: Nabidae), which were negatively affected by the carbofuran treatment during the first cutting period. Pitfall trap catches of CRC adults were very small in all plots, regardless of insecticide treat- ment. Catches of slugs were not significantly different between plots.

Greenhouse.—Flats treated with the high rate of carbofuran had significantly taller al- falfa under simulated no-tillage conditions in the greenhouse (Table 3). Although the car- bofuran did not prevent a decline in stem den- sity, the increased growth resulted in increased yield at the high carbofuran rate under no-till conditions. However, under simulated conven- tional-tillage conditions, no effects of carbofur- an application were apparent. DISCUSSION The seedbeds used in this study were old, declining alfalfa stands which contained a res- ident root-inhabiting CRC larval population. Few CRC adults were collected by sweep-net, pitfall or emergence trapping in the treatment area, including the untreated control plots. However, the 4 emergence traps placed in al- falfa surrounding the treatment area contained a high population of CRC adults (4.1 and 15.5/ trap, 1985 and 1986, respectively), and a con- current study in another part of the old field indicated that CRC larvae had been present (J.C.P., unpublished data). We believe that the resident CRC larval population was reduced prior to the carbofuran treatment by the her- bicide application used to kill all existing vege- tation before no-tillage planting during 1985. Once the existing alfalfa and clover plants were killed the larvae may have starved before the establishment of the new seedling root systems.

An inconsistent growth response due to car- bofuran was observed in the field, and stem density loss was not prevented by the carbofur- an. Grant et al. (11) arrived at the same con- clusion using a low rate of carbofuran [1.1 kg (AI)/ha] while establishing alfalfa into sod. Byers et al. (12), working in conservation-til- lage alfalfa following alfalfa, found none of the mean alfalfa yields of plots treated with different combinations of carbofuran [1.1 kg (AI)/ha], herbicides, and a molluscicide to dif- fer significantly from that of the check. Alfalfa stem heights were greater in no-til- lage than in conventional-tillage greenhouse trials. The greater organic matter content of the no-tillage flats may have slowed the leach- ing of the carbofuran from the flats, thereby increasing its availability for plant uptake. Also, the bare soil of the conventional-tillage flats would absorb much more heat in the green- house, which could lead to hotter, drier soil conditions and subsequently, reduction of plant growth, regardless of carbofuran treatment. In contrast to the tillage response observed in stem length, stand densities were greater in conventional-tillage trials. Stand decline in no- tillage trials was believed to be due to com- petition from weeds which recovered from the herbicide treatment. Flats were hand-weeded on a regular basis to control broadleaf weeds but grasses were impossible to eliminate from the sod. In summary, an inconsistent seedling growth response resulted from the application of car- bofuran at the time of planting alfalfa under no-tillage conditions. The positive response to carbofuran in some instances may have been due to the control of root-inhabiting CRC lar- vae, nematodes or some other factor not sam- pled in this study, or to the presence of plant diseases in the unresponsive plots. A more con- sistent positive response to carbofuran may re- sult if the granules are placed in the furrow with the seed. Stand establishment under no- tillage conditions will remain erratic and un- predictable until we have a greater under- standing of the influence of insects, nematodes, slugs, diseases, and field history on alfalfa seed- ling establishment.

SMILEY Department of Chemistry, Eastern Kentucky University, Richmond, Kentucky 40475 AND VICKIE TRIANTAFYLLAKIS! Department of Chemistry, University of Kentucky, Lexington, Kentucky 40506 ABSTRACT A spectrophotometric technique was used to obtain formation constants of ethylenediaminetetraacetic acid (EDTA) complexes of Cr(III), Co(II), Ni(II), and Cu(II) at temperatures of 30, 40, 60, and 80°C. Enthalpies of formation were endothermic showing the free energy to be entropy controlled. INTRODUCTION Although a considerable number of publi- cations can be found related to formation con- stants of ethylenediaminetetraacetic acid (EDTA) complexes (1-4), most of them report values at standard temperatures, with only a few constants measured at 40°C. Temperature dependence on these formation constants are of interest from both a practical and thermo- dynamic standpoint. The formation constants of the complexes are based on the reaction M" + Y*- > MY?~4, where M® represents a metal ion and Y rep- resents EDTA. From the law of mass action the formation constant is given by: _ [MYe4] [M"Y*"] If the molar concentration of the complex at equilibrium is C,, the concentrations of the unreacted “free” metal ion and EDTA are C,, — C, and C, — C,, respectively, where C,, and C, represent initial concentrations of metal ion and EDTA. Consequently, the equilibrium constant for the formation of the complex, K., is: (1) ' This paper is part of a M.S.

However, equation 1 implies that all the uncombined EDTA is present in the complete- ly dissociated form Y*. At lower pH values, though, the uncombined EDTA will also be present also in its protonated forms HY*, H,Y?-, H3Y!, and HyY, which vary in their 86 TRANS.

For measurement of the absorbances at higher temperatures, a Model 123-0702 Hitachi ther- mostatted 10 mm Path Cell Holder was also used. This attachment is composed of a ther- mostatted cell holder and a temperature con- troller, and can maintain a constant temper- ature of a cell filled with sample between 30- 80°C. The temperature range accuracy is +1°C for the temperature range of 30-50°C, and +1.5°C for 50-80°C. To ensure complex formation, equimolar mixtures of the metal ion and the disodium salt of EDTA were prepared, using deionized water as a solvent (Table 2). The absorbance was measured as a function of time, starting immediately after mixing the reagents. In all cases, with the exception of Cr(III), the absor- bance graphs measured at different time in- tervals were within instrumental error (i.e., within +0.3%) indicating a rapid complex for- mation. The spectrum of an equal concentra- tion of the metal ion was also recorded and compared to the spectrum of the complex. In this manner, total absorbances, A,, and molar absorptivities of the metal ions, ¢,, were de- termined at the indicated temperatures, and the data are listed in Tables 3 and 4, respec- tively. To find the molar absorptivity of the com- plex the following method was used: keeping the concentration of the metal constant, the EDTA amount was varied, and the absorbance was plotted vs. the EDTA/metal concentration ratio.

Vari- ations on the flatness of the 100% line were corrected by subtracting the absorbance of this line from the absorbance curve of the sample. DiscussION Using the technique described above, for- mation constants for the 4 metal complexes were determined at the indicated tempera- tures, and the values are listed in Table 6. From the slopes of the plots of In K,,,, vs. 1/T neg- ative slopes, indicating positive enthalpies of formation, were determined. The values de- termined for AH from the least squares de- termination of the slopes are somewhat ques- tionable since the correlation coefficients vary from 0.84 to 0.99 and the standard deviations of the slopes have higher than desired values, with the exception of the Ni(II) system (Table 7). However, the slopes are definitely negative indicating positive values for AH. The expres- sion for the Gibbs free energy is AG = AH — TAS (9) Inspection of this equation, in conjunction with experimental results, leads to the conclusion that the formation of the reported EDTA com- TaBLE7.

The Gibbs free energy, AG, must have a negative value in order for the formation of the complex to oc- cur. Since AH, as determined from the slope of In K,,,, vs. 1/T, has a positive value, then AS must have a positive value in order for TAS to offset the positive AH, resulting in a negative value for AG. This is not surprising since the metal ions are hydrated to 6 water molecules and, the formation of the complex releases these 6 molecules, resulting in a more disordered state than that represented by the reactants. From the slopes of the plots of In K,,,, vs. 1/T, the enthalpies of formation of the com- plexes were determined. The values are listed in Table 7. The values of K,,,, reported here are con- centration values rather than thermodynamic values. Ideally K,,,, should be determined at different concentrations and plotted as a func- tion of concentration such that an extrapolated value at infinite dilution could be obtained. This would represent the thermodynamic val- ue of K,,,,, since, at this condition all activity coefficients would be unity. The thermodynamic formation constant is given by the expression K= A complex (10) ay “am where agompless Ay, and a,, represent the activ- ities of the complex, the unreacted ligand, and the unreacted metal ion, respectively.

BARNEY Community Research Service, Kentucky State University, Frankfort, Kentucky 40601 ABSTRACT This paper compares 4 precision-based and 1 fixed-error probability sequential sampling models to de- termine which would be most suitable for use in an alfalfa weevil (AW), Hypera postica (Gyllenhal), integrated pest management program. Field tests indicated that the precision-based models with a precision (D) of 0.3 require essentially the same average number of samples to terminate sampling as the fixed-error probability model. However, using either of the precision-based models (D = 0.3) in an integrated pest management program when the fixed-error probability model is desired will result in too many management errors because they do not identify the range of population densities (i.e., intermediate zone) within which management decisions are unreliable. One method for calculating such an intermediate zone for use with precision-based models is discussed. INTRODUCTION The stem-count technique for assessing al- falfa weevil (AW), Hypera postica (Gyllen- hal), larva infestations was first used by Hamlin et al. (1) and entailed removing stems within a square-foot quadrat and extracting the larvae in the laboratory. This technique provided ab- solute estimates of AW larva densities but was quite laborious. Subsequent modifications of this technique involved collecting individual stems over the entire alfalfa field with rec- ommended number of stems ranging from 1 20-stem sample (2) to 10 50-stem samples (3). These modifications have generally improved the utility of this technique for an integrated pest management (IPM) program. A stem- count technique (4) is currently being used in Kentucky's AW IPM program and involves collecting 1 30-stem sample per field. The 30-stem technique was recently re- viewed (5) and was found to provide imprecise mean-density estimates which can lead to con- siderable management errors. This situation is primarily caused by collecting just one sample per field; collecting as many as 10 30-stem samples per field can greatly reduce the per cent of management errors but requires too much time to be cost effective (5). To facilitate multiple sample collecting, Legg et al. (6) suggested collecting 1 6-stem sample from each of several randomly selected 100-m? subunits per field. This technique was found to be quite efficient when compared with col- 89 lecting either 6 stems from 2,500-m? areas or 12 stems from 100- or 2,500-m? subunits per field (6). Using the 6-stem, 100-m? sampling tech- nique, Barney and Legg (7) constructed 4 pre- cision-based sequential sampling models (pre- cision [D] is defined as the ratio of the standard error of the mean to the mean) and have also constructed a computer-based fixed-error probability sequential sampling system (8). Precision-based sequential sampling models require that a predetermined level of precision be reached before sampling is terminated. Pre- cision-based models do not, however, control the probability of misclassifying a population density relative to an economic threshold (ET). Fixed-error probability sequential sampling models control the probability of misclassify- ing a population relative to an ET but they do not control the precision at which mean pop- ulation densities are estimated. Fixed-error probability models are more desirable for use in IPM programs because they facilitate the rapid classification of a pest population density into high or low categories relative to an ET, thus controlling the probability of misclassifi- cation. Use of the fixed-error probability sequential sampling system of Legg and Barney (8) would require purchasing a portable computer. Pres- ently, this would be economically feasible only for a select group of individuals (e.g., private IPM consultants, industry, and scouts in special university-sponsored IPM programs). Alter- 90 TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3-4) natively, the low-cost precision-based models are available but little is known about their probability of misclassifying a population den- sity relative to an ET. To explore the possibility of substituting precision-based sequential sam- pling models for the fixed-error probability model in an AW IPM program, we evaluated each model’s performance as measured by number of samples required for sampling ter- mination, observed precision and mean pop- ulation density estimates. In addition, the probability of misclassifying a population den- sity when using the precision-based models was estimated over a range of population densities. MATERIALS AND METHODS Thirteen alfalfa fields in Franklin County, Kentucky, were selected for sampling and rep- resented a range in stand densities and ages. Each field was sampled weekly from 4 April through 7 May 1987 using 4 precision-based sequential sampling models (7), a fixed-error probability model (8) and a comprehensive whole-field sampling effort which served as an experimental control (whole-field control). Precision-based models (D = 0.2 and 0.3) were based on the equations of Kuno (9) and Green (10). The fixed-error probability model was based on Iwao’s (11) equation and operated in a BASIC program that ran on an Epson HX- 20 hand-held computer. Order of visitation to fields within week and the order of sampling models per visit per field were random. The 6-stem, 100-m? sampling technique (6-stem count technique) (6) was used for all 5 models and the whole-field con- trol. Briefly, the 6-stem count technique en- tailed randomly selecting 100-m? subunits from each field and collecting 6 stems from each subunit. Collected stems were vigorously shak- en into a plastic bucket (10 liter) to dislodge large larvae. Dislodged larvae were emptied into a white enamel tray where they were counted. Subunits were independently and randomly selected for each model and whole- field control per visit per field. The 5 models and whole-field control were used in each field on each visit for 3 weeks except on 3 occasions when AW densities were too low to use the precision-based models at D = 0.2. Thirteen fields were sampled each week providing a total of 228 samples. Average number of AW larvae and variance were calculated per sampling model and whole- field control per visit per field. Total number of samples required for model termination was also recorded. These statistics were used to cal- culate precision. Dependent variables of in- terest were mean AW densities, precision, and required number of samples for model ter- mination. These are important statistics in IPM- related work. Unlike the sequential sampling models, the whole-field control functioned independently of population density and hence the number of samples required to terminate sampling was not a response variable. To create a varying response for this sampling method, we selected a sample size range (n = 10-13 samples) within which the total number of samples was ran- domly chosen at each visit to each field. Based on the work of Barney and Legg (7), we felt that a minimum of 10 samples was necessary to consistently provide mean AW population estimates that would be more precise than those of the precision-based models (i.e., D < 0.2). This arrangement provided an estimate of variance. Variances within each dependent variable were tested for homogeneity between the sequential sampling models and whole-field control by calculating the s?,,a./S?min Statistic (where s?,,,,, and s?,,;, are the largest and small- est variances, respectively) and comparing it with the tabulated upper 5% value (12). Data were then transformed, when necessary, to sta- bilize the variance. Transformations used were x!?> and \/X for number of samples and cal- culated precision, respectively. Data were subjected to a split-plot analysis of variance with sampling week (a time factor) representing the whole plot, fields within week being factor a, and sampling model and whole- field control within fields being factor b. Com- putations were facilitated by using the Linear Analysis of Variance Procedure of STATISTIX (13). Orthogonal linear contrasts (14) were con- ducted to determine the significance of 5 spe- cific comparisons: (1) whole-field control vs. all sequential sampling models, (2) precision-based models vs. fixed-error probability model, (3) precision-based models at D = 0.3 vs. preci- sion-based models at D = 0.2, (4) Green’s pre- cision-based models at D = 0.3 vs. Kuno’s pre- cision-based model at D = 0.3 and (5) Green’s SAMPLING MODELS IN ALFALFA WEEVIL CONTROL—Legg and Barney 91 precision-based model at D = 0.2 vs. Kuno’s precision-based model at D = 0.2. Significance of these comparisons was determined by Stu- dent’s ¢ test. In addition, 4 nonorthogonal con- trasts were performed to determine whether their contribution to the sums of squares of each dependent variable was significant: (1) Green's and Kuno’s precision-based models at D = 0.3 vs. the fixed-error probability model, (2) Green's precision-based model at D = 0.3 vs. the fixed-error probability model, (3) Ku- no’s precision-based model at D = 0.3 vs. the fixed-error probability model and (4) Green’s and Kuno’s precision-based models at D = 0.2 vs. the fixed-error probability model. Since these latter comparisons were neither orthog- onal to one another nor to the previous group of comparisons, their significance was deter- mined by Scheffé’s (15) F test which is de- signed for use with arbitrary simultaneous comparisons. Linear contrasts and related sta- tistics were computed by the General Contrasts Option of STATISTIX (13). The probability of misclassifying a popula- tion density when using the precision-based models was determined by the methods of Bar- ney and Legg (5). These involved collecting 5 6-stem samples for each visit to each of 4 alfalfa fields (7) and calculating, for each visit to each field, the variance (s?) and mean population density (x). These statistics were then trans- formed to the Napierian log scale (In) with In(s?) being regressed on In(x) (16) using Bart- lett’s (17) method (s? = 1.0124%!?""; 95% con- fidence interval for slope = 0.37, 2.19; r° = 0.37). A computer program (18) was used to facilitate computations of this regression. Us- ing this relationship, the average variance can be estimated for each mean population den- sity. Forty-two means, selected to cover the range (2-32) of AW larvae per 6 stems that are usually found in the field, were substituted individually into this equation to calculate their respective variances. Each of the 42 selected means and variances was then used to generate 100 sets of 3, 7, and 11 6-stem samples; thus spanning the range of very low (3) to very high (11) numbers of samples per population den- sity. Each set of 6-stem samples was randomly selected from an assumed normal distribution. Although insect populations are rarely nor- mally distributed, the distribution of sample averages often conforms to the normal as the number of samples increases (14). Averages were calculated for each set of 3, 7, and 11 samples per population density, and compared with each of 6 ETs that were selected to cover the range of AW densities normally encoun- tered in the field (3, 7, 12, 16, 21, and 26 larvae per 6-stem sample). From these comparisons 1 of 2 possible management decisions were made (to apply or not to apply an insecticide) with each resulting in one of the following situations: (1) the estimated average and the true average were below the ET and a hypo- thetical insecticide application was not made (correct decision), (2) the estimated average was greater than the ET but the true average was less than the ET and an unnecessary in- secticide application was made (unnecessary spray), (3) the estimated average and the true average were greater than the ET and an in- secticide application was made (correct deci- sion), and (4) the estimated average was less than the ET but the true average was greater than the ET and a necessary insecticide ap- plication was not made (failure to spray). Pro- portion of unnecessary sprays was calculated by summing the number of unnecessary sprays and dividing it by 100. Proportion of failures to spray was calculated by summing the num- ber of failures to spray and dividing it by 100. RESULTS AND DISCUSSION Analysis of variance for mean AW larva es- timates indicated that significant differences did not occur between any of the sampling models and/or whole-field control (F = 0.39, P = 0.86, df = 5,124). Therefore, linear con- trasts were not conducted for this variable. Analysis of variance for number of samples and precision, however, indicated that signif- icant differences existed between some of the sampling models and/or whole-field control (number of samples: F = 145.5, P < 0.0001; precision: F = 4.7, P = 0.0006; df for both analyses = 5,124). Linear contrasts for number of samples and precision are shown in Tables 1 and 2, from which the following conclusions can be made: (1) average number of samples required for terminating sampling and ob- served precision of the sequential sampling models was much less than that of the whole- field control. These results were expected and they reflect both the savings in sampling effort 92 Trans. KENTUCKY ACADEMY OF SCIENCE 49(3-4) realized through the use of sequential sampling models over the whole-field control and the lower precision associated with fewer samples. (2) Average number of samples required to terminate sampling was lower for the preci- sion-based models with D = 0.3 than for the precision-based models with D = 0.2. This re- sult was expected since required number of samples is less for lower precision. (3) Average number of samples required to terminate sam- pling and observed precision of all precision- based models (combined) or the precision-based models with D = 0.3 was not different from that of the fixed-error model. Number of sam- ples required to terminate sampling was, how- ever, greater for precision-based models with D = 0.2 than for the fixed-error probability model. Interestingly, average observed preci- sion did not differ between precision-based models with D = 0.2 and the fixed-error prob- ability model. These results indicate that the precision-based models with D = 0.3 will not require more effort, as measured by number of samples, than the fixed-error probability model. Also, the average precision realized when using the fixed-error probability model is essentially equivalent to but is more variable than that of the precision-based models. From the results obtained thus far it appears that either of the precision-based models with D = 0.3 can be substituted for the fixed-error probability model in an AW IPM program. However, fixed-error probability models pos- sess an “intermediate” category that corre- sponds to observed population densities which are too near the ET for distinct classification into “high” or “low” categories at the maxi- mum allowable proportion of unnecessary sprays and failures to spray. Precision-based models do not have this intermediate zone. One method of determining the interme- diate zone for the precision-based models is to calculate, via computer-simulated sampling experiments, the probability of misclassifying mean population densities for each ET at var- ious population densities. These probabilities can then be used to estimate, via the standard normal curve, AW densities corresponding to the specified proportion of unnecessary sprays and failures to spray. Population densities be- tween and including those associated with these error probabilities constitute the intermediate zone. Probabilities of misclassifying mean A W lar- va population densities when the estimates were based on 3, 7, and 11 6-stem samples are shown in Figure 1. Maximum errors (height of the curves) occur, as expected, when population densities are nearest the ET (5). Height of the curves was not reduced when the number of samples was increased from 3 to 11 but the proportion of errors was reduced when the number of samples was increased as mean pop- ulation densities moved away from the ET (width of the curves). It appears that relatively few errors occurred at very low population densities (3 larvae per 6-stem sample) as com- pared with very high population densities (26 larvae per 6-stem sample). Width of the curves increased noticeably from the lowest to highest ET for mean estimates that were based on 3 6-stem samples but this trend was reduced when 7 and 11 6-stem samples were taken. Curves for the normal distribution were fit- ted to these data and the average AW larvae per 6-stem sample corresponding to a 0.25 probability of spraying unnecessarily and a 0.20 probability of failing to spray were calculated for each ET and each level of sample number per mean. These values were then pooled over sample number per mean and regressed on their respective ETs (Fig. 2). Relationships for controlling the number of unnecessary sprays (bottom regression) and failures to spray (top regression) were linear and explained 99% of the observed variance. These equations may now be used to calculate error zones for any ET that is based on a 6-stem sample. Resulting error zones, however, are valid only for AW population estimates calculated from 11 or fewer samples. It is now possible to modify Kentucky’s AW IPM program to make use of these new sam- pling technologies. Such modification will in- volve 4 phases: adoption of the 6-stem, 100-m? sampling method, selection of a precision-based model (D = 0.3), calculation of error zones, and modification of the AW IPM recommen- dation tables (i.e., replacing the ETs with error zones). Implementation would be a straight- forward process of sampling a field with the selected model, estimating the average AW population density, and consulting the error zone corresponding to the correct cumulative degree days and alfalfa growth stage. If the average AW population density is less than the 93 SAMPLING MODELS IN ALFALFA WEEVIL CoNTROL—Legg and Barney ss0 80=4 IIg‘0 6020 Jepow AypIqeqord 10119-paxty @0 = d S[epoul paseq-uors}oa1g 66'0 F00 =4 IIg‘0 6080 Japow AqyIqeqoid 10119-paxty 0 = C ‘[epoul paseq-uorstoaid s ouny 660 600 =a4 I1g0 0820 Jepour AqyIqeqoid Io119-paxty €0 = C ‘Jepow paseq-uorstoaid s u9e15) 00'T 000 =a I1e0 #620 [apow AqpIqeqoid so118-paxty $0 = C ‘S[apoul paseq-uolstoa1g 662F'0 80=2 FEZ ‘0 S810 20 = C ‘[epow paseq-uolstoaid s ouny 70 = C ‘[epour paseq-uolstoaid s usais ISFI‘0 FRI=2 6080 08Z'0 §0 = ‘Jepoul paseq-uoisioaid s ouny 0 = C ‘[epou paseq-uorstoaid s usaisg, F9TO'0 Ipt— =} 6020 F620 70 = C ‘S[epoul paseq-uorstoaig $0 = C ‘s[epow paseq-uorsioo1g $8920 Ill =?

RODRIGUEZ Department of Entomology, University of Kentucky, Lexington, Kentucky 40546 ABSTRACT Some commercial types of pollen (plum, pecan, pistachio, apple, kiwi fruit, almond and pear) were compared with local corn pollen as alternate foods for Neoseiulus fallacis (Garman), an important phytoseiid predator of orchard mites. Efficiency of food as measured against time required for development between egg oviposition and adult emergence, as influenced by relative humidity (RH), pointed to pistachio as a superior alternate food and 85% RH promoting the most rapid development. These same pollens were challenged under the same RH conditions by 2 additional phytoseiids, Phytoseiulus persimilis Athias-Henriot and Typhlodromus occidentalis (Nesbitt) and monitored for egg production as a parameter of food efficiency. None of these pollens were nutritionally adequate to continue oogenesis beyond exhaustion of the stored-up food reserve, from prey consumed while the predator females were in the immature stages. Other corollary studies with N. fallacis demonstrated that locally produced tulip poplar pollen provided adequate nutrition, and was comparable to pistachio but Zumi crab apple was superior since it sustained 11 continuous generations without supplementation with prey. INTRODUCTION Phytoseiid mites have long been recognized as an important component in the manage- ment strategy of tetranychid mites, especially in orchards. This family of predator mites gen- erally develops and reproduces best when preying on spider mites but can subsist on such alternate foods as pollen, scale crawlers and honeydew (1, 2). Pollens from various sources have often proven to be acceptable and effi- cient alternate foods for some species of phy- toseiids, as shown by McMurtry and Rodriguez (3) who recently reviewed the nutritional ecol- ogy of phytoseiids. The main objectives in this study were to examine comparative acceptance and general nutritional efficiency of 10 different pollens on 3 important phytoseiid predators, namely, Phytoseiulus persimilis Athias-Henriot, Neo- seiulus (=Amblyseius) fallacis (Garman) and Typhlodromus occidentalis (Nesbitt). Major emphasis was given N. fallacis, an important predator of apple orchard mites in Kentucky. MATERIALS AND METHODS The predatory mites, P. persimilis, N. fal- lacis and T. occidentalis were sub-cultured from stocks maintained in the Acarology Lab- ' Present address: Acarology Division, Faculty of Ag- riculture, Cairo University, Giza, Egypt. 96 oratory. The prey, the twospotted spider mite (TSSM), Tetranychus urticae (Koch), was highly acceptable in all stages to the 3 species of phytoseiids in our study (3). The experi- ments were conducted under laboratory con- ditions of 16 hr photoperiod and 27°C. DEVELOPMENT OF N. FALLACIS Detached bean leaves were divided into 6 sections by streaks of tree Tanglefoot® and were placed on moist filter paper in petri dishes (90 mm diam). The dishes were in turn placed in clear plastic containers (19 x 28 cm) contain- ing saturated salts to provide relative humid- ities (RH) of 75, 81, 85, 92, and 97 per cent. In addition, water only was included in one treatment to provide nearly 100% RH. Seven commercial types of pollen grains, namely, al- mond, apple, kiwi fruit, pear, pecan, pistachio and plum (Fireman Pollen Co., Stockton, Cal- ifornia) plus corn pollen from a local hybrid cornfield, were individually supplied on the leaf surface as food for the predator, N. fal- lacis, that developed from one egg placed on each section. The immature stages of N. fal- lacis were transferred every 2 days to detached bean leaves and pollen grains. Data were ob- tained from 12 mites observed from each treat- ment. In a corollary study, this same group of pol- lens were tested for their influence on longevity of N. fallacis, adult emergence to death (N = 24). PoLLEN Diet IN PREDATOR MitEs—Afifi et al. 97 POLLEN EFFICIENCY IN N. FALLACIS DEVELOPMENT In these tests, the same pollen types (except that local tulip poplar was substituted for corn) used previously were placed on 90-mm disks cut from black polyethylene sheeting and di- vided into 6 sections with Tanglefoot. One N. fallacis egg was placed in each section and distilled water was supplied by soaking a small lump of filter pulp. The rearing dishes (N = 24) were maintained at 90% RH with other conditions as described previously. Growth and life stage development were determined. Two other corollary tests were also con- ducted. One test involved apple pollen and prey fed to 2 generations of N. fallacis. In another study, crab apple pollen (University of Kentucky Farm) of the Zumi variety was used as food for N. fallacis. Growth/devel- opment, longevity, and fecundity were deter- mined. The tests were conducted on disks cut from black polyethylene with conditions as de- scribed above. STUDIES ON EGG PRODUCTION Detached bean leaves were partitioned into 6 approximately equal parts with use of Tan- glefoot. Newly emerged male and female N. fallacis and T. occidentalis were offered the same 8 pollen types and the test was repeated 4 times. Males were removed after 2 days and the females (N = 24) were then maintained for 15 days using the same procedures and conditions as in the previous study. The Tan- glefoot confinement method used successfully for N. fallacis and T. occidentalis proved un- suitable for P. persimilis, hence a Plexiglas® rearing cell was used for this species. The cell consisted of 3 Plexiglas pieces. The top and bottom were 3 mm in thickness and 4 x 6 cm. The middle piece had a thickness of 6 mm and a hole 2.5 cm in diameter which together with the bottom and top pieces comprised a cell. The top piece was vented with a hole 0.6 cm in diameter and covered with a cemented fine mesh screen. Bean leaf disks (3 cm in diameter) were placed in the rearing cells (N = 20) and pollen grains were supplied as food. The as- sembled cell was held together with rubber bands. Again, rearing conditions/procedures were as used in the studies described previ- ously. TaBLE 1.

The test proce- dure entailed isolating N. fallacis eggs and rearing the immatures to adults (N = 25). Egg production was then monitored over a 28 day period. RESULTS DEVELOPMENT OF N. FALLACIS Neoseiulus fallacis fed and developed on all pollen types and at all RH levels tested. The effects of various pollen types on development as influenced (from oviposition to adult emer- gence) by RH are shown in Table 1. Generally, the 85% RH promoted the shortest develop- ment time, especially when compared against 75% and 100% RH (Table 1). Only in the case of pecan and kiwi pollens were these differ- ences, i.e., between 85% RH and the extremes, not significant. Examining the effect of pollens on development time, pistachio clearly was su- perior to other pollens, accelerating rate of de- velopment, followed by pecan or corn. Kiwi fruit or apple were the least efficient (Table 1). In the corollary study on longevity (tabu- lated data not given for sake of brevity), pis- tachio pollen prolonged adult longevity to the greatest degree, a mean of 47.8 days at 85% RH as compared to kiwi fruit, the most likely to shorten life, with 41.5 days. None of the pollen types used as food during the life span of N. fallacis proved suitable for egg produc- tion. 98 TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3-4) TaBLE 2.

FALLACIS DEVELOPMENT Pistachio pollen provided the highest per cent of individuals reaching the adult stage (77.8%) followed by tulip poplar, apple and pecan pollens in the moderate range while plum, kiwi fruit, almond, and pear were the most inefficient, ranging from 30% (plum) to 6% (pear) (Table 2). The adults were then mat- ed and each female was isolated, and fed the same pollen on which it had developed. Tulip poplar pollen gave 60% of adult development and females laid an average of 33.6 eggs during 28 days. There was no egg production in N. fallacis when fed other pollens at this time. When N. fallacis was fed apple pollen dur- ing its developing stages, 56% reached adult stage but did not produce eggs. These adults were then supplied with spider mites and sub- sequently an abundance of eggs were pro- duced. F; immatures were 80% developed into adults when fed on apple pollen. When those female adults were once again fed spider mites they produced eggs that resulted in emergence of an F, generation (Table 3). TaBLE 3.

Zumi crab apple pol- len was readily accepted and N. fallacis was successfully reared on this pollen for 11 gen- erations (Table 4). Ecc PRODUCTION The oviposition study on the 3 phytoseiid species, N. fallacis, P. persimilis and T. occi- dentalis, involved the use of newly emerged mated females. They were fed on the various pollen types (see Tables 1, 2) for 15 days. This study showed that a small quantity of eggs were produced over the initial 2 to 3 day pe- riod. However, females ceased to oviposit after this initial period, indicating that the prey food reserve built up during the immature stages had been exhausted. No significant differences were found among the 8 pollen types analyzed across all humid- ities or humidities analyzed across all pollens. The initial egg production was the result of the immature stages previously feeding on the spider mites. The results of this test indicated that these 8 pollen types, when supplied as food for the 3 phytoseiid predators, proved to be nutritionally deficient for oviposition. How- ever, the pollens could sustain the mites for a limited period. It should be noted, however, that local crab apple (Zumi) pollen was used in another test to successfully rear 11 gener- ations of N. fallacis (Table 4). A diet regimen of prey eggs was slightly more efficient nutritionally than a diet of pro- tonymphs. When offered a meridic diet (Table 5), development of egg to adult occurred, but egg production did not occur. When this diet was supplemented with tulip poplar pollen, egg production (1.2 per day) occurred, and this POLLEN Diet IN PREDATOR MitEs—Afifi et all. 99 TaBLE5.

DISCUSSION AND CONCLUSION Neoseiulus fallacis that fed on the various pollen types at various RH levels for its entire life span had a developmental rate that was generally significantly affected by the pollen types when analyzed across all RH_ levels. However, the effects on adult female longevity were not significant. The mite, during larval, protonymphal and deutonymphal stages, must feed before developing to the subsequent stage. Food value and acceptability can greatly in- fluence the development of these life stages, as was shown by feeding the various pollen types. The 8 pollens used in the study to determine their efficiency, as measured by egg produc- tivity in the 3 predator species, proved to be nutritionally inadequate. Egg production did not occur after the initial burst of oviposition, demonstrating that the immature stages feed- ing on prey eggs laid down food reserves es- sential for oogenesis but once that limited re- serve was exhausted, oogenesis did not continue under a pollen food regimen. The specific na- ture of pollen adequacy, however, was appar- ent by the comparative efficiency of Zumi crab apple pollen that successfully produced 11 suc- cessive generations of N. fallacis without the benefit of spider mite prey. By the same token, while P. persimilis and T. occidentalis ac- cepted Zumi pollen, they did not produce eggs. Ahlstrom and Rock (4) reported that N. fal- lacis fed and reproduced on pollens from the trumpet creeper vine and the tulip poplar. Moreover, this species adapted and accepted these pollens as food, as indicated by the in- creasing percentage of immatures reaching adult stage, from 55.6 in the parent generation to 80 and 87 per cent in the first and second generation respectively. Phytoseiid mites vary in their ability to ef- ficiently convert pollen food into resources for egg production. For example, pollen grains of castor bean, avocado, maize and carpobrotus (Mesembryanthemum) were shown in labo- ratory studies to have high food value for Euseius (=Amblyseius) hibisci (Chant) and Amblyseius limonicus Gar. MCG. (5, 6). Am- blyseius hibisci was continuously cultured on pollen alone, but T. occidentalis Nesbitt did not feed on pollens (7). Phytoseiulus persimilis and T. occidentalis failed to oviposit when fed an artificial diet, while E. hibisci, A. largoensis (Muma) and T. arboreus (Chant) developed and oviposited when fed on both oak pollen and on artificial diet (8). When the artificial diet was combined with tulip poplar pollen and fed to N. fallacis, the females produced an average of 2.1 eggs per female per day, compared to 2.3 when TSSM protonymphs were provided as food. It was demonstrated that the three phyto- seiid predators, P. persimilis, N. fallacis and T. occidentalis, can survive for a period of time on various pollens. This is a very important attribute for these predators, especially during the absence of the natural prey. Pollens vary in their chemical composition and not all pollen types are efficient food for phytoseiids (3). Our results also support Ken- nett and Hamai (8) who found that neither P. persimilis nor T. occidentalis oviposited when fed on any food other than tetranychid mites. Finally, although the 3 phytoseiid predators may accept different pollens, generalizations 100 cannot be made on nutritional adequacy. Neo- seiulus fallacis is clearly a species that can live and reproduce on certain pollens such as Zumi crab apple. Studies are needed to determine why tulip poplar and Zumi crab apple pollens are superior food and to examine techniques of utilizing these pollens in orchards as alter- nate foods.

BATCH Department of Biological Sciences, Eastern Kentucky University, Richmond, Kentucky 40475 ABSTRACT Collecting in 55 counties yielded data for 19 families, 45 genera, and 138 species of Kentucky land snails and slugs. Five species were previously unreported from the state: Vertigo rugosula Sterki, V. parvula Sterki, Arion subfuscus (Draparnaud), Oxychilus draparnauldi (Beck), and Polygyra cereolus (Muhfeld). Ecological and distributional information is presented for each species. A general biogeographical discussion pertaining to the relationships of the Kentucky terrestrial gastropod fauna is presented that suggests a relationship principally with the fauna of the southeastern United States and, to a lesser degree, with that of the midwest and the east. INTRODUCTION Since publication of the principal checklists of Kentucky land snails (1, 2), many taxonomic and biogeographic changes have been reported in the literature. In order to bring interested investigators up to date, the more recent find- ings are summarized. Hubricht (3) relegated Glyphyalinia burringtoni Pilsbry to the syn- onymy of G. wheatleyi (Bland) and elevated to full generic level Megapallifera from a po- sition of subgenus in Pallifera, Megapallifera includes M. mutabilis (Hubricht), M. ragsdalei (Webb), and M. wetherbyi (W. G. Binney). In 1977, Hubricht (4) found that Catinella va- gans (Pilsbry) was probably a distinct species rather than a synonym of C. vermeta (Say) and described Paravitrea subtilis and Cary- chium riparium, both from Kentucky. During that period, Vitrizonites latissimus (Lewis) and Vertigo clappi (Brooks and Hunt) were re- ported from Kentucky (5), as was Glyphyalinia raderi (Pilsbry) (6). Petranka’s (7) thesis re- search recorded Vertigo bollesianna (Morse), Mesomphix rugeli (Binney), and Triodopsis dentifera (Binney) from the state. Finally, in a much needed revision of known terrestrial molluscan distribution in the eastern United States, Hubricht (8) summarized the recent family and generic changes that have been wrought during the last 12 years. The most important changes, affecting the Kentucky fauna, follow: Cionella was placed in the genus Cochlicopa and C. lubrica morseana (Doher- ty) was elevated to full species; Vallonia per- spectiva Sterki was reported from Kentucky; Columella edentula (Draparnaud) was placed in the synonymy of C. simplex (Gould); Suc- cinea forsheyi I. Lea was reported from Ken- tucky; Philomycus togatus (Gould) was ele- vated to full species; Megapallifera mutabilis (Hubricht) was reported; Pallifera secreta (Cockerell) was resurrected as a full species, as was Anguispira strongyloides (Pfeiffer) and A. rugoderma (Hubricht); Discus catskillensis (Pilsbry) was elevated to full species and H. fimbriatus Wetherby was reported from the state; Mesomphix globosus (MacMillan) was reported; Paravitrea subtilis Hubricht and P. blarina Hubricht were reported, as was Ha- waiia alachuana Dall; Ventridens elliotti (Redfield) was shifted into Zonitoides; and Eu- conulus dentatus (Sterki) was resurrected and reported from Kentucky. In the Polygyridae, Hubricht (8) reported Polygyra troostiana I. Lea from the state and restricted the range of P. fatigiata (Say) to extreme western Kentucky only; Mesodon panselenus Hubricht was re- ported, but not M. perigraptus (Pilsbry); M. laevior Hubricht was retained as a full species distinct from M. appressus (Say); Triodopsis rugosa anteridon Pilsbry was elevated to full species; T. fraudulenta (Pilsbry) was not re- ported; and T. hopetonensis (Shuttleworth) was reported. In spite of all this recent information, the distributional data on the Kentucky terrestrial molluscan fauna remain woefully inadequate and incomplete. Many of the counties have not been sampled for mollusks. Thus, this contri- bution attempts to partially rectify this situa- tion by presenting data from 55 Kentucky counties, plus some data from adjacent Vir- 101 102 TRANS.

RESULTS In the annotated list that follows, specimens are correlated with collecting sites by station number. The figures in parentheses represent the sample size in each case. The taxonomic designations, except where noted, follow Hu- bricht (8). Family Helicinidae Two genera and species of the primitive or- der Archaeogastropoda occur in Kentucky. These are operculated, mostly calciphilic land snails with a propensity for moist ravines in Kentucky, although Helicina is often found on relatively dry, grassy hillsides. Helicina orbiculata (Say) Collections: 12 (1). Although locally abundant, the distribu- tion of this species is poorly understood in Kentucky. It prefers sunny locations (8) but is often found along the margins of woods. Hendersonia occulta (Say) Collections: 5(3), 12 (1), 15 (2), 148 (1), 146 (1). All these sites were in moist ravines with an abundance of decaying vegetation and fairly deep horizon A soil. Fresh specimens are usually pale rusty red in color, although yellowish is not uncommon (8). Family Carychiidae Because of their minute size and habitat in leaf litter and soil, the distribution of the species of Carychium in Kentucky is poorly delineat- ed. Furthermore, some of the species are rel- atively difficult to distinguish, causing some confusion in the literature. Burch and Van De- vender (9) published excellent keys and pho- tographs of the described species, and their LAND SNAILS IN KENTucKy—Branson and Batch taxonomy is followed here. Data for three species are reported. Carychium clappi Hubricht Collections: 4 (12), 10 (50), 13 (7), 125 (1). The only previously reported records for this species in Kentucky were from Harlan County (5, 7), and some authors (9) do not consider the species to be distinct from C. exile canadense Clapp. Carychium exiguum (Say) Collections: 10 (23), 13 (3), 16 (1), 115 (10). Because confusion between this species and C. exile, records from Kentucky may be in confusion. Carychium nannodes Clapp Collections: 4 (9), 10 (23), 13 (7), 16 (6), 73 (9). As our records indicate, this very slender species is often found associated with C. exiguum. It is one of the smallest snails in America, measuring only 1.3-1.5 mm in length (8). Family Cochlicopidae Formerly included in the family Cionellidae (1, and elsewhere), the genus Cionella has been placed in the synonymy of Cochlicopa with 4 species in North America (8), one of which is known from Kentucky. Cochlicopa morseana Doherty Collections: 2 (9), 13 (1), 34 (1), 43 (1), 119 (2), 134 (1). Hubricht (8) has C. lubrica (Muller) and C. morseana as full and distinct species, which we accept. This very secretive, wood- lands species is often missed by general col- lectors. The habitat is mostly in moist de- caying wood and leaves, although it is often found deep beneath piles of unconsolidated rocks, Family Valloniidae Distributional data for these small ground- dwelling snails is very limited for Kentucky. Soil sieves are required for efficient collecting. Data for 3 species are presented. Vallonia pulchella (Miller) Collections: 2 (2), 4 (15), 10 (61), 13 (1), 16 (1), 115 (5), 125 (18). This small, white species prefers grassy fields, lawns, and weedy hillsides (8), where 105 it is most easily collected by means of grad- uated soil sieves. Vallonia costata (Miller) Collections: 4 (145), 10 (110), 13 (4), 16 (3), 49 (6), 91 (8). Living in a habitat similar to the last men- tioned, this species is often collected with V. pulchella. Vallonia perspectiva Sterki Collection: 115 (2). The only other record for this species in Kentucky is from Mercer County (8). The snail should be sought in heavily wooded ravines and talus slopes. Family Pupillidae Since most of these small to minute, seed- like snails are easily overlooked during col- lecting, the poor representation in Kentucky records is not startling. Data for 4 genera and 14 species are reported here. Pupoides albilabris (C. B. Adams) Collections: 24 (2), 28 (3), 29 (1), 50 (6), 115 (13), 125 (1), 187 (1). The largest species of the family, this snail frequents grassy areas, open hillsides, wood- land margins, and similar habitats. Gastrocopta armifera (Say) Collections: 10 (2), 13 (2), 16 (1), 24 (6), 27 (1), 38 (1), 44 (1), 50 (4), 56 (1), 77 115 (69), 125 (8), 130 (1). Found mostly in open, sunny areas, this snail is not infrequently found in marginal forests. Hubricht (10) separated G. clappi (Sterki) from G. armifera, raised it to full species level, and listed it from 3 Kentucky counties (8). The two forms are easily dis- tinguished by means of the characters pre- sented by Hubricht (10): in G. armifera the columellar lamella has a forward-projecting lobe and the shell measures 3.7-5.0 mm in length and 2.0-2.6 mm in diameter. In G. clappi there is no forward-projecting lobe on the columellar lamella and the shell is smaller, 3.5-4.3 mm in length and 1.8-2.0 mm in diameter. There is an excellent il- lustration of G. clappi on page 876 of Pils- bry’s (11) monograph. Gastrocopta contracta (Say) Collections: 4 (7), 10 (17), 13 (6), 16 (1), 24 (1), 29 (4), 32 (5), 115 (60), 125 (9), 130 (10). 106 TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3-4) A very environmentally plastic species, G. contracta doubtless occurs throughout Ken- tucky. Gastrocopta pentadon (Say) Collections: 10 (11), 13 (4), 29 (1), 115 (3), 125 (8). Often confused with the next species, which is larger, this species prefers upland woods with well-drained, calcareous soils. Gastrocopta tappaniana (C. B. Adams) Collections: 115 (2), 125 (1), 130 (1). With far fewer records from Kentucky than G. pentadon, G. tappaniana lives in moist situations, mostly on floodplains, around ponds and lakes, and in swamplands. Gastrocopta corticaria (Say) Collections: 4 (21), 10 (25), 13 (7), 115 (1). Prior to this report, G. corticaria was known from Clark, Jefferson, and Edmon- son counties only. It is a moist forest species. Gastrocopta procera (Gould) Collections: 4 (1), 115 (4), 116 (1). This thick-shelled snail has habitat re- quirements similar to those of Pupoides al- bilabris. Vertigo rugosula Sterki Collection: 10 (1). Not previously reported from Kentucky, this species prefers rather dry situations on open hillsides. Vertigo ovata Say Collection: 10 (2). The only other record for this lowland species in Kentucky is from Edmonson County (1). Vertigo ventricosa (Morse) Collections: 10 (2), 16 (2), 125 (2). Previous records for this lowlands, mois- ture-loving snail were from Harlan (8) and Madison (1) counties. Vertigo tridentata Wolf Collections: 8 (1), 115 (5), 125 (2). This very small snail lives in moist, low- land situations, usually on the lower sides of fallen leaves. Vertigo parvula Sterki Collection: 115 (1). Heretofore unknown from Kentucky, this minute species is similar to V. tridentata, though it is much smaller, measuring about 1.5 mm in length and 0.9 mm in diameter. According to Pilsbry (11) it is a relatively rare species. The favored habitat is leaf litter (8). Vertigo gouldi (A. Binney) Collections: 115 (1). Of widespread but sporadic occurrence in Kentucky, this is another small snail that prefers leaf litter as habitat. Columella simplex (Gould) Collections: 4 (1), 10 (1), 27 (1), 29 (1). This is not acommon species in Kentucky, nor does it apparently produce large pop- ulations where it is found in moist lowland woods and ravines. Previously reported from Kentucky as C. edentula (Draparnaud) (1), a name now placed in the synonymy of C. simplex (8). Family Strobilopsidae Three species of Strobilops are known from Kentucky. We present data for one. Strobilops labyrinthica (Say) Collections: 45 (1), 91 (6), 145 (1). Mostly a woodlands species with an affin- ity for leaf litter and decaying wood. Family Succineidae The amber snails, of which 3 genera and 9 species have been reported from Kentucky (1, 8), is a rather difficult taxonomic group. In most instances dissection of the reproductive organs is required for species designation. We report data for 2 genera and species. Succinea ovalis Say Collections: 3 (18), 5 (7), 8 (1), 23 (2), 32 (1), 62 (1), 113 (3), 115 (1), 134 (2), 136 (8). This distinctive succineid is most often found in moist woodlands or on floodplains. Catinella avara (Say) Collections: 29 (1), 52 (1), 83 (1), 92 (1). The records established in Kentucky for C. vermeta (Say) apply to C. avara (8). The snail inhabits lowland situations, mostly around bodies of water. Family Philomycidae Slugs are more often than not slighted in regional treatments of terrestrial mollusks. They are difficult to preserve satisfactorily and many of them must be dissected to verify species diagnoses. Three genera are known from Ken- tucky. LAND SNAILS IN KENTuCcKY—Branson and Batch Philomycus carolinianus (Bosc) Collections: 7 (1), 33 (1), 63 (4), 64 (2), 98 (9). This variable slug prefers floodplains and moist upland woods as habitat. Hubricht (8) elevated the subspecies P. carolinianus to- gatus (Gould) to full species. Philomycus flexuolaris Rafinesque Collections: 3 (1), 64 (1), 94 (1). For many years P. flexuolaris was consid- ered as a subspecies of P. carolinianus (11). It is an upland congener of the latter species (8). Philomycus virginicus Hubricht Collection: 7 (1). Another uplands woods slug, this species was previously known from Pike, Madison (1), and Harlan (7) counties. Philomycus venustus Hubricht Collections: 12 (1), 60 (2), 95 (1), 96 (3), 98 (2), 114 (1), 124 (1). This pale slug prefers moist woods as hab- itat. Hubricht (8) placed P. bisdosus Branson in its synonymy. Pallifera dorsalis (A. Binney) Collection: 3 (1). Previously reported from Pike, Wolfe, Powell, and Madison counties (1), this dis- tinctive slug is most often found in leaf litter of moist forests. Pallifera fosteri F. C. Baker Collections: 27 (1), 64 (2). Hubricht (8) removed P. secreta (Cock- erell) from the synonymy of this species, and reported it from several Kentucky localities. Megapallifera ragsdalei (Webb) Collections: 13 (1), 27 (1). This large slug prefers moist, wooded ra- vines and streamside bluffs. Family Discidae The members of this family were previously placed in the Anguispiridae (Anguispira) and the Endodontidae (Discus) (1). The other gen- era previously assigned to the Endodontidae are now assigned to the families Helicodiscidae (Polygyriscus, Helicodisus) and Punctidae (Punctum). Anguispira alternata (Say) Collections: 3 (1), 8 (1), 10 (2), 13 (3), 16 (8), 22 (2), 28 (8), 29 (1), 32 (1), 43 (2), 48 (3); 80 (1), 101 (4), 102 (2), 115 (4), 119 (5). 107 This is a highly variable species, partic- ularly with regard to the peripheral angu- lation of the body whorl (8). Hubricht (8) believes that, along with some of the differ- ences in sculpturing, is the result of intro- gressive hybridization with the next species but it is more apt to reflect a plastic genome and ecophenotypy. Anguispira mordax (Shuttleworth) Collections: 5 (1), 12 (14), 40 (8), 56 (3), 81 (1). This heavily sculptured (rib striate) snail is widespread in Kentucky. Breeding exper- iments need to be accomplished to give cre- dence to Hubricht’s (8) hypothesis of wide- spread hybridization between A. mordax and A. alternata. Anguispira kochi (Pfeiffer) Collections: 17 (3), 28 (3), 130 (1), 141 (1). Anguispira kochi prefers undisturbed, moist, wooded ravines. The species is not common in Kentucky and may be worthy of consideration for inclusion on the threat- ened list (12). Discus cronkhitei (Newcomb) Collections: 1 (11), 18 (4), 24 (3), 28 (1), 34 (4), 49 (1), 115 (5), 119 (7), 125 (8). This small, heavily sculptured snail fre- quents moist ditches and woodlands, often in association with the next two species. Discus catskillensis (Pilsbry) Collection: 1 (11). Usually found in uplands woods near logs (8), this species was previously known from Fulton, Daviess, and Henderson counties (8). Discus patulus (Deshayes) Collections: 3 (2), 10 (4), 12 (1), 13 (18), 15 (1), 16 (1), 17 (2), 23 (3), 29 (2), 56 (5), 98 (30), 99 (4), 127 (1), 189 (3), 144 (4). One of the largest species in the genus, D. patulus has a strong affinity for wet, de- caying wood in upland forests. Discus rotundatus (Miiller) Collection: 47 (3). This introduced species (11) has not been found in Kentucky but doubtless occurs in Jefferson County in the vicinity of Louis- ville. Family Helicodiscidae There are at least 8 species of Helicodiscus known from Kentucky. We present data for 2 of them. 108 Helicodiscus parallelus (Say) Collections: 28 (1), 92 (1), 98 (1), 115 (1), 125 (4). Primarily found in woods associated with leaf litter and decaying wood, this species is also often found in ditches, around wooden houses, and in trash. Helicodiscus singleyanus (Pilsbry) Collections: 4 (1), 28 (1), 115 (1), 125 (2). Previously known from Floyd, Fayette, and Jefferson counties only, this minute white snail prefers open, grassy habitats (8). Family Punctidae Four species of these minute snails are known from Kentucky (1). Punctum lamellatum Hu- bricht has been synonymized with P. smithi Morrison (8). Punctum minutissimum (I. Lea) Collections: 4 (2), 10 (15), 115 (8). The preferred habitat is deep leaf litter, and the species is seldom found elsewhere. Sieves must be used to secure specimens. Punctum vitreum H. B. Baker Collection: 29 (1). Known previously from Edmonson and Spencer counties only, P. vitreum is one of America’s smallest snails, measuring only about 1.3 mm in diameter. The habitat is identical to that of the last species. Family Arionidae Arionid slugs are Holarctic in distribution, with native species occurring in the western segments of North America, Asia, Europe, and north Africa (11). There are several introduced species of Arion in the eastern and western United States and adjacent Canada (11). None of these sometimes noxious species have here- tofore been reported from Kentucky. Arion subfuscus (Draparnaud) Collection: 123 (2). All arionids live in areas of relatively high rainfall. This dull, dark-brown slug with two indistinct black, longitudinal bands on the mantle, was introduced into America from central Europe (11). Family Limacidae Most of the dozen or more genera and large number of species of limacid slugs are natives of Europe and adjacent parts of Africa and TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3-4) Asia, although several species in the genera Lehmannia, Limax, Deroceras, and Milax have been introduced into America (11). Represen- tatives of all these genera have been found in Kentucky, including the single native species Deroceras laeve. Lehmannia valentianus (Ferussac) Collections: 2 (8), 4 (1), 82 (4), 93 (2). Previously reported from Bell County only, this European exotic is widespread in and around greenhouses. The colony on the University of Kentucky campus is a large one. Limax maximus Linnaeus Collections: 2 (4), 50 (1), 74 (1), 79 (8). Another European exotic, this large (100 mm or more), yellowish-gray, mottled slug is a common urban species and is often found in large numbers at trash-dumping sites. It can become a garden pest. The specimen from Station 74 was melanistic. Milax gagates (Draparnaud) Collection: 50 (1). This record indicates that Milax is per- sisting in Madison County, where it was pre- viously reported (13), the only known lo- cality in Kentucky. Deroceras reticulatum (Miller) Collections: 32 (2), 50 (6), 61 (5), 64 (1), 147 (1). Still another European exotic, this slug has become widely distributed in North Amer- ica through agricultural commerce. It is a common garden pest, often in association with the next species below. Deroceras laeve (Miller) Collections: 1 (1), 23 (1), 93 (2), 142 (1). The only native limacid slug in Kentucky, this species doubtless occurs throughout the state in spite of the few published records. Family Zonitidae With the Polygyridae, the Zonitidae is one of the most speciose molluscan families in America. It is second to none in Kentucky, being represented by a long list of genera and species. However, biological and distributional data are scanty for the small to minute species. Nesovitrea electrina (Gould) Collections: 13 (1), 72 (1), 85 (1). Known previously from Jefferson and LAND SNAILS IN KENTucKY—Branson and Batch Daviess counties, this small, nearly trans- parent snail frequents wet lowlands. Nesovitrea binneyana (Morse) Collection: 36 (1). Previously recorded from Henderson and Union counties, N. binneyana lives in up- land woods in leaf litter. Glyphyalinia cumberlandiana (Clapp) Collections: 10 (4), 117 (2). Only recently reported from Kentucky (5, 7, 8), this snail’s habitat is in leaf litter and decaying wood in forested ravines, sink- holes, and rocky, shaded hillsides. Glyphyalinia wheatleyi (Bland) Collections: 21 (1), 29 (1), 84 (1). The habitat is similar to that of the last species. Glyphyalinia rhoadsi (Pilsbry) Collection: 125 (4). Only recently reported from Kentucky (8), this beautiful little snail occurs in much of eastern Kentucky, mostly in upland forest litter. Glyphyalinia indentata val Collections: 3 (2), 29 (4), 84 (1), (1), 99 (1), 115 (84), 117 (1), 121 (12), 126 (1), 131 (2). Occurring in many kinds of habitats, G. indentata is the most widespread member of its genus. As pointed out by Hubricht (8), G. indentata so-called is actually a complex of very similar species awaiting monograph- ic treatment. There are at least 3 morpho- logically different species in Kentucky, 2 in the eastern highlands. 85 (2), 95 (1), 125 Glyphyalinia caroliniensis (Cockerell) Collection: 6 (1). Mostly a species of leaf litter in the Cum- berland Mountains. Glyphyalinia cryptomphala (Clapp) Collections: 9 (1), 29 (6), 56 (1), 71 (1), 115 (10). Because the next species was for many years considered as a subspecies of G. cryp- tomphala (14), the distribution of both species in Kentucky is probably confused. The preferred habitat is leaf litter along riv- er blufts. Glyphyalinia solida B. Baker) Cerone aa Pe eee ), 56 (2), 84 (3), 91 (1), 95 (2), 98 (1), 101 (3), 117 (1), 121 (1). 109 This rather large Glyphyalinia is usually found in leaf litter and decaying wood in ravines or on rocky hillsides. Glyphyalinia praecox (H. B. Baker) Collections: 99 (2), 100 (1). A beautifully sculptured snail, G. praecox prefers leaf litter on rocky hillsides and ad- jacent floodplains. Glyphyalinia sculptilis (Bland) Collection: 12 (6). Mostly found in upland forests in leaf lit- ter. Mesomphix inornatus (Say) Collections: 3 (2), 5 (13), 6 (8), 7 (2), 8 (8), 29 (2), 53 (1), 60 (1), 89 (5), 98 (1), 104 (1), 106 (1), 112 (3), 114 (1), 119 (1). Mesomphix rugeli (W. G. Binney) Collections: 3 (1), 5 (5). Thus far known only from Harlan Coun- ty, this species is found principally on wood- ed hillsides on relatively high mountains such as Black and Pine mountains. Mesomphix latior (Pilsbry) Collections: 2 (1), 7 (1), 12 (1). Previously known from Bell County only, M. latior has an exceptionally flat apex. It prefers leaf litter in upland woods. Mesomphix perlaevis (Pilsbry) Collections: 3 (5), 5 (4), 7 (5), 18 (1), 29 (1), 32 (3), 40 (1), 91 (4), 98 (6), 114 (1), 119 (2). With M. inornatus one of the most abun- dant species of the genus in eastern Ken- tucky, this species has habitat requirements like those of M. latior. Mesomphix vulgatus H. B. Baker Collections: 7 (1), 8 (1), 11 (1), 12 (1), 28 (1), 27 (1), 59 (1), 91 (2), 108 (1). Mesomphix vulgatus, of which M. dero- chetus Hubricht is a synonym, is somewhat variable in coloration and sculpturing. The specimen from Station 59 may be M. glo- bosus (MacMillan). Mesomphix friabilis (W. G. Binney) Collections: 13 (5), 53 (1). A species of floodplains and low-lying ad- jacent bluffs, M. friabilis is often confused with the next species. Mesomphix cupreus (Rafinesque) Collections: 3 (3), 6 (6), 7 (1), 18 (2), 32 110 TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3-4) (1), 56 (10), 60 (1), 102 (4), 110 (1), 119 (3), NPAT): This thin-shelled snail is mostly found in the leaf litter of uplands woods. Mesomphix capnodes (W. G. Binney) Collection: 6 (1). Previously known from Warren, Cum- berland (8), and Powell and Bell (1) counties in Kentucky, M. capnodes is usually found in upland woods underlain by calcium rocks (8). Vitrizonites latissimus (Lewis) Collections: 3 (14), 5 (5). Although previously reported from Har- lan County (5, 7), additional comments on this interesting Blue Ridge Province snail are in order. The colony is apparently a rather large one in the mesophytic environments of this area. However, clearcutting and/or stripmining could easily eliminate the prop- er habitat. The snail should be listed as of Special Concern since this is the only pop- ulation known in Kentucky. Paravitrea multidentata (A. Binney) Collection: 91 (1). This 2.5 mm snail has an internal arma- ture arrangement like that described for P. m. forma lamellata H. B. Baker (14). How- ever, shells with these oblique rows of la- mellae (instead of the more common rows of teeth) do not seem to be of taxonomic importance (8). Paravitrea placentula (Shuttleworth) Collections: 12 (2), 58 (1). This is one of the most common species of Paravitrea in eastern Kentucky, mostly in leaf litter. Paravitrea cf. capsella of various authors Collections: 18 (2), 27 (2), 29 (1), 95 (2), 99 (2), 115 (7), 121 (4). Hubricht (8) has ascertained that what most authors have been diagnosing as P. cap- sella is actually a complex of several species that cannot be distinguished by shell char- acteristics alone. Hubricht (pers. comm.) is working on a revision of the group. Paravitrea reesei Morrison Collection: 7 (1). Previously known from Pike County only (1), this small snail frequents leaf litter along river bluffs (8). The shell is waxen white with incised radial striations and bears within the aperture 3 prominent teeth in a row. There are 6 whorls. Hawaiia minuscula (B. Binney) Collections: 2 (1), 10 (1), 24 (1), 29 (2), 85 (1), 91 (1), 115 (13), 125 (30). Although reported sporadically only, mostly because of the small size, this species is widespread in Kentucky. Since Hubricht (8) has elevated H. alachuana Dall to full species (Jefferson, Union, Hickman, and Fulton counties), collectors should use cau- tion in diagnosing specimens from western Kentucky. The latter species is a calciphile in leaf litter, whereas H. minuscula is a ground-dwelling species, seldom being found in leaf litter (8). Gastrodonta interna (Say) Collections: 5 (3), 6 (2), 12 (2), 18 (1), 15 (3), 24 (1), 32 (1), 56 (2), 98 (4), 103 (1), 120 (1), 128 (1), 140 (1). A secretive species that is widespread in the eastern half of the state in moist woods, G. interna is one of the most easily identified members of the family. Ventridens collisella (Pilsbry) Collection: 3 (5). A lowland species that is mostly restricted to calcium-rich soils in leaf litter (8). Ventridens pilsbryi Hubricht Collection: 12 (1). Ventridens pilsbry appears to be restrict- ed in distribution to southeastern Kentucky counties, where it is found mostly in leaf litter. Ventridens theloides (Walker and Pilsbry) Collections: 3 (2), 5 (2), 6 (6), 13 (2), 39 (4), 98 (3). Previously known as a subspecies of V. gularis, Hubricht (8) elevated V. theloides to full species and relegated V. gularis nodus Pilsbry and V. nodus Pilsbry to its synony- my. Hence, all records published previously under the epithet V. nodus should be re- listed as V. theloides. Ventridens lawae (W. G. Binney) Collections: 39 (1), 98 (1). Although locally abundant, this species is not found much beyond the Cumberland Mountains. Ventridens lasmodon (Phillips) Collections: 36 (1), 84 (2), 98 (34). LAND SNAILS IN KENtucKY—Branson and Batch Another species entirely restricted to southeastern Kentucky, V. lasmodon prefers leaf litter as habitat. Ventridens gularis (Say) Collections: 3 (1), 5 (1), 6 (3), 12 (3), 18 (2), 95 (1), 98 (18), 103 (1), 117 (9). Widespread in Kentucky, V. gularis is found mostly in forest leaf litter and on floodplains. Ventridens demissus (A. see) Collections: 3 (28), 5 (1 me (3), 7 (1), 18 (2), 14 (1), 16 (2), 24 (2), 3 ees 40 (1), 55 (7), 75 (1), 84 (9), 95 (4), 97 (1), 98 (3), 101 (8), 115 (15), 121 (4), 136 (1), 146 (1). The most widespread Ventridens in Ken- tucky, V. demissus lives in many types of habitats, from lowlands to rock hillsides. Ventridens percallosus (Pilsbry) Collections: 12 (2), 36 (2). Previously known from Todd County only, V. percallosus occupies a habitat similar to that of V. demissus, though it is much less common. Ventridens ligera (Say) Collections: 6 (1 » 8 (1), 16 (1), 23 (2), 29 (6), 46 (1), 67 (3), 92 (1), 93 (2), 117 (6). Ventridens ligera mostly avoids slopes, preferring weedy, wet lowlands (8). Ventridens intertextus (A. Binney) Collections: 6 (3), 12 (1), 8 (1), 9 (1), 24 (16), 28 (2), 52 (13), 110 (1). The habitat is mostly woodland leaf litter (8), but the species is often found on a sand- stone substrate. Ventridens suppressus (Say) Collection: 36 (2). Previously known from Pike and Harlan counties (1, 8), this is another woodlands snail with affinities for leaf litter. Zonitoides elliotti (Redfield) Collection: 36 (1). Previously placed in the genus Ventri- dens (1, 14) on the basis of shell morphology, this odd little snail has been reassigned to Zonitoides (8). The preferred habitat is thick leaf litter near decaying wood. Zonitoides lateumbilicatus (Pilsbry) Collection: 85 (1). Found mostly in woods on calcium-rich soils, this species does not appear to maintain large populations in Kentucky. lll Zonitoides arboreus (Say) Collections: 8 (1), 10 (1), 16 (1), 21 (1), 36 (1), 39 (1), 50 (4), 55 (2), 115 (1), 119 (83), 125 (3). The most widespread member of its ge- nus, this little amber snail is found in many types of habitats, from woodlands to flood- plains and city gardens. Oxychilus draparnauldi (Beck) Collection: 132 (3). An introduced species from Europe and adjacent Africa, O. draparnauldi has not previously been reported from Kentucky. In the United States, the snail is usually found around human habitations and disturbed areas. The snail, measuring 15-17 mm in diameter and 6-8 mm in height, is trans- lucent when fresh, light tan above and paler below, with 5% whorls, the last of which is much wider than the others. The large um- bilicus is contained about 6 times in the greatest diameter (14). The snail is preda- ceous upon invertebrate animals, including other snails. Striatura milium (Morse) Collections: 10 (3), 13 (1), 29 (1). Previously known from Edmonson Coun- ty only, this is one of America’s smallest snails, measuring about 1.5 mm in diameter and 0.75 mm in height. Usually with 3 whorls, the beautifully sculptured shell is usually found by sifting leaf litter. Family Helicarionidae Most of the older literature includes the members of this family in the Zonitidae (14). Three genera are known from the eastern United States, Dryachloa (Florida, Alabama), Euconulus, and Guppya. Representatives of the last two genera occur in Kentucky. Euconulus fulvus (Miller) Collections: 29 (3), 115 (9). This small, broadly domed-shaped species is found primarily in moist leaf litter. Euconulus chersinus (Say) Collections: 16 (1), 29 (1), 115 (8). Collectors should use care in identifying this species for it is often collected with E. trochulus (Reinhardt) and E. dentatus (Ster- ki), especially in the western two-thirds of the state (8). 112 Guppya sterkii (Dall) Collections: 10 (8), 18 (1). This minute (1.2 mm diameter, 0.7 mm height, 3% whorls) snail is usually found in moist leaf litter. Family Haplotrematidae Haplotrema concavum (Say) Collections: 3 (1), 5 oe S (2), ie (3), 12 (3), 18 (2), 15 (1), 2 48 (1), 49 (5), 56 (3), 6 Rr aeR 89 (1), 94 (3), 95 (1), 98 (8), 99 ( 115 (4), 119 (4), 121 (2). This carnivorous snail doubtless occurs throughout Kentucky. Family Bulimulidae Mostly a western-southwestern family of snails, the Bulimulidae is represented in west- ern Kentucky by a single species. Rhabdotus (Bulimulus) dealbatus (Say) Collection: 75 (12). This relatively large, mottled, heliciform snail lives around low vegetation and grasses. In Kentucky, it has been reported from War- ren and Logan counties only (1). Family Helicidae Cepaea nemoralis (Linnaeus) Collections: 86 (10), 132 (2). This pretty, banded, multicolored species, an exotic from Europe, is known in Ken- tucky from Boone, Fayette, and Franklin counties (1, 15). Family Polygyridae Of the larger land snails, the Polygyridae is the most speciose and widely distributed in Kentucky. Polygyra cereolus (Muhfeld) Collection: 37 (5). This Floridian snail has been widely dis- seminated in shopping malls and green- houses by the importation of subtropical vegetation. The species also occurs in the greenhouses at Eastern Kentucky Universi- ty. It has not been previously reported from Kentucky. Polygyra plicata (Say) Collections: 12 (6), 19 (1), 62 108 (2), 117 (1), 118 (18). Mostly a species of calcium-rich forest (5), 75 (3), TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3-4) floors, this snail is sometimes locally abun- dant. Stenotrema evardsi (Bland) Collections: 3 (6), 5 (3), 6 (2), 13 (2), 28 (2), 36 (1), 98 (5), 119 (1), 121 (2), 180 (1). Stenotrema evardsi is widespread in leaf litter in the eastern third of Kentucky. Stenotrema barbatum (Clapp) Collections: 10 (1), 29 (4), 40 105 (1), 128 (1). Although principally a lowland, flood- plains snail, S. barbatum is found associated with decaying wood in eastern Kentucky. (1), 104 (2), Stenotrema angellum Hubricht Collections: 18 (1), 119 (2). Often confused with the next species be- low, S. angellum lives in leaf litter and around decaying logs (8), mostly on upland slopes.

There is considerable phenotyp- ic variation. ), 9 ), 1 2 1 4] ( 1 Stenotrema hirsutum (Say) Collections: 12 (1), 23 (2), 40 (1), 56 (1), 91 (1), 92 (1), 98 (7), 120 (3). This small species is found mostly in leaf litter on well-drained slopes. Stenotrema leai aliciae (Pilsbry) Collections: 10 (1), 16 (1), 18 (2), 42 (1), 49 (1), 66 (1), 75 (3), 104 (2), 115 (2). The principal habitats are in lowland sit- uations in grass, decaying wood, and in floodplains woods (8). Stenotrema fraternum (Say) Collections: 8 (1), 10 (7), 34 (1), 41 (2), 70 (2), 78 (1), 85 (2), 120 (1), 126 (1), 180 (1), 181 (1). The specimen from Station 34 resembles S. fraternum montanum Archer (16). In all cases the habitat was in leaf litter and under logs. Mesodon rugeli (Shuttleworth) LaNpD SNAILS IN KENTucKY—Branson and Batch Pas 3 (9), 6 (1), 8 (8), 9 (1), 10 (3), 12 (4), 18 (2), 15 (6), 18 (6), 28 (1), 24 (1), 25 (3), 2 & ), 32 (1), 56 (3), 88 (1), 84 (3), 89 (3), 91 (4), 98 (1), 105 (1), 109 (1), 114 GQ) eas an ENE75 (AUTO 82) SLA (4) 136 (3). Although this snail mostly frequents up- land woods, it apparently sometimes hy- bridizes with M. inflectus (17). Mesodon inflectus (Say) Collections: 5 (18), 7 (1), 8 (1), 23 ( (5), 28 (7), 32 (1), 50 (5), 51 (1), 52 (3 (8), 75 (6), 101 (26), 105 (1), 117 (2). Contrasted with S. rugeli, M. inflectus is principally a lowlands species, usually found on floodplains, rocky outcrops, leaf litter, and often in urban gardens. Mesodon appressus (Say) eager 4 (1), 6 (3), 13 (4), 18 (3), 24 (3), 40 (1), 4 14 ), 49 (10), 88 (12), 89 (4), 9 98 (3), 99 (4), 114 (1), 1 hy (2), 122 (5), 130 (9), 141 (4). A very widespread species under woody vegetation on rocky slopes, in moist ditches, and in urban settings, M. appressus is a vari- able species by way of sculpture and size. Specimens from various sites on Pine Moun- tain are consistently smaller than average (14.0-14.6 mm in diameter, 6.8-7.5 mm in height) and have angular peripheries. The base is marked by close-set, thread-like, raised spiral striae. This form warrants ad- ditional investigation, including the repro- ductive anatomy. It is probably an unde- scribed species. Mesodon laevior Hubricht Collection: 98 (2). Originally described as a variant form of M. appressus based upon specimens from Mammoth Cave National Park, Warren and Wayne counties (16), Hubricht officially de- scribed the species in 1968 (2). Mesodon perigraptus (Pilsbry) Collections: 53 (9), 60 (2), 89 (3). Previously known from Pike and Bell counties in Kentucky, this distinctive poly- gyrid prefers leaf litter in upland woods as habitat. Hubricht (8) did not map this snail in Kentucky (8, 19). Mesodon wetherbyi (Bland) 2), 7 ), NNOWrH ear Op = ie co) Ze bo — = 113 Collection: 12 (2). Known only from Pulaski, Laurel, Mc- Creary, and Whitley counties in Kentucky and 5 adjacent counties in Tennessee, this snail is nowhere common. Mesodon sayanus (Pilsbry) Collections: 3 (13), 6 (2), 60 (1), 69 (1), 89 (1), 91 (1), 98 (2), 112 ea 14 (1), 119 (1), 122 (1). Specimens of this woodlands species from Black Mountain average larger than any we have seen elsewhere. Mesodon chilhoweensis (Lewis) Collections: 7 (5), 140 (1). Following extensive collecting in southern Kentucky, this large polygyrid (regularly 40 mm in diameter) remains known from McCreary County only (1). The center of distribution is principally east Tennessee, where it lives in leaf litter and around de- caying logs. Hubricht (8) believes that the population size is kept at low numbers by predation from birds. Mesodon elevatus (Say) Collections: 10 (2), 11 (5), 12 27 (1), 31 (4), 32 (1), 110 (8). These records double the known range of this heavy shelled species in Kentucky. The preferred habitat is wooded bluffs above rivers and large creeks (8). (1), 15 (1), Mesodon zaletus (A. poe Collections: a ),6 : Veet (2) Sid ie CY) 13 (2), 14 (8), 2 Se 8 (4), 32 (1 Pe 5 (19), 56 (1), 76 (3), 9 1 (2), 110 (3), 119 (1), 128 (1), 129 (2). Another species that prefers river-bluff forests, although found elsewhere, M. zale- tus is sometimes confused with Triodopsis albolabris. Mesodon normalis (Pilsbry) Collection: 3 (2). First reported from Kentucky by Hu- bricht (20) in McCreary County, this large species has been treated as a subspecies of M. andrewsae W. G. Binney (16). Hubricht (8) elevated it to full species. Mesodon nor- malis represents an extension of a Tennes- see—North Carolina complex into Kentucky. Mesodon downieanus (Bland) Collections: 51 (9), 52 (9), 54 (2), 95 (8), 125K): 114 Hubricht (8) contends that he has never seen M. downieanus north of Tennessee (re- stricts the distribution to Tennessee and Al- abama), preferring to call specimens from southern Kentucky M. kalmianus Hubricht. However, we are unable to distinguish be- tween M. downieanus from Kentucky lo- calities and those from Tennessee, or be- tween M. kalmianus and M. downieanus. Mesodon mitchellianus (I. Lea) Collection: 87 (3). This species’ known habitat includes low- land meadows and floodplains (8). Mesodon burringtoni Hubricht is a synonym. It was previously known from Bell, Harlan, and Nicholas counties only. Mesodon clausus (Say) Collections: 4 (1), 8 (2), 11 (1), 12 (1), 18 (3), 23 (3), 29 (2), 34 (1), 83 (4), 84 (1), 94 (1), 97 (2), 101 (5), 109 (1), 121 (3), 122 (8). Found principally in moist lowland situ- ations, M. clausus is sometimes confused with M. downieanus. Mesodon thyroidus (Say) So eee 6 (2 a (5), 10 (1), 11 (1), 12 (1), 18 (6), 17 (3), 24 (1), 26 (1), 28 (1), 29 (1), 51 (2), 52 (18), 55 (3), 56 (1), 58 (1), 75 (1), 89 (3), 91 (1), 94 (1), 98 (2), 99 (1), 101 (1), 107 (1), 110 (1), 111 (2), 115 (3), 119 (2), 185 (1). One of the most widely distributed poly- gyrids in the Commonwealth, M. thyroidus is found mostly in floodplain woods, but it is not uncommon on rocky slopes and in urban settings. Mesodon wetherbyi (Bland) Collection: 7 (2). Known from Laurel, Pulaski, McCreary, and Whitley counties only, this is another species that represents an extension from the Blue Ridge Province into Kentucky. It pre- fers moist leaf litter and decaying wood as habitat. Triodopsis anteridon Pilsbry Collections: 3 (8), 12 (1), 18 (8), 138 (1). Previously reported from Kentucky as T. rugosa anteridon, this form has been ele- vated to full species (8). Hubricht (8) re- stricted the range of T. rugosa Brooks and MacMillan to its type locality in West Vir- TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3-4) ginia. Thus, all records from Kentucky are based upon T. anteridon. Triodopsis fraudulenta (Pilsbry) Collections: 8 (3), 29 (1), 35 (2), 119 (3). Not a very common species in Kentucky, this snail prefers leaf litter on upland slopes for habitat. Triodopsis vulgata Pilsbry Collections: 8 (1), 67 (1), 121 (2). This is a locally common snail in the leaf litter of upland forests. Triodopsis claibornensis Lutz Collections: 3 (9), 5 (1), 6 (1), 98 (1). Previously known from Whitley County, Kentucky (1) and from two counties in ad- jacent Tennessee (8), T. claibornensis is yet another extension from the Tennessee fauna into the Commonwealth. Triodopsis discoidea (Pilsbry) Collection: 117 (5). The habitat of this locally common snail is principally beneath rocks and logs on river bluffs (8). Triodopsis tridentata (Say) (2), 89 (2), 95 Collections: 9 (3), AY ), 12 (2), 18 (3), 15 (1), 27 (3), 28 (5), 2 me 40 (5), 52 (15), 65 (1), 83 (1), 84 (7), 91 (19), 98 (1), 99 (3), 120 (6), 121 (8), 128 (2). In the usual habitat—leaf litter and around logs in upland forests (also occurs ina variety of other situations)—T. tridentata com- monly constitutes 45% of randomly collect- ed polygyrids, and Mesodon appressus 30- 32%. Triodopsis juxtidens (Pilsbry) Collection: 99 (3). This species was long considered as a sub- species of T. tridentata until Hubricht (21) elevated it to full species. The snail, rela- tively less common than T. tridentata, is probably widespread in Pike, Floyd, and Letcher counties. Adult shells are around 17.5-18.5 mm in diameter, and the outer tip of the parietal tooth is directed toward a point above the outer lip tooth or directly at it. However, the apertural teeth of T. tridentata are variable in shape and size (22). Triodopsis tennesseensis (Walker and Pilsbry) Collections: 9 (1), 60 (4), 87 (6), 98 (4). LAND SNAILS IN KENTucKY—Branson and Batch Considered to be a subspecies of T. tri- dentata until Hubricht (23) elevated it to full species, this snail is widely distributed in the eastern half of the Commonwealth. Triodopsis complanata (Pilsbry) Collections: 8 (1), 10 (1), 18 (8), 18 (2), 56 (6), 84 (1), 91 (1), 120 (3), 133 (1), 189 (2). This relatively large snail, which prefers leaf litter and decaying wood on river bluffs as habitat, is not very common in its range. However, Hubricht (8) limited its distribu- tion to the south side of the Cumberland River in the vicinity of Lake Cumberland. Triodopsis denotata (Férussac) Collections: 7 (1), 12 (1), 18 (1), 104 (1), 119 (1), 130 (2). Although relatively widespread in the state, this snail does not appear to maintain large populations. Triodopsis fosteri (F. C. Baker) Collections: 13 (2), 40 (4). In Kentucky, T. fosteri is a very uncom- mon snail, one which ought to be considered for listing by the Rare and Endangered Species Committee. Triodopsis albolabris (Say) Collections: 3 (2), 5 (3), 6 (1), 9 (1), 10 (1), 12 (1), 28 (2), 35 (6), 53 (1), 56 (2), 75 (11), 98 (2), 112 (1), 117 (2), 120 (4). Since this species is often confused with Mesodon zaletus, collectors should use care in diagnosing dead specimens. Triodopsis dentifera (A. Binney) Collections: 3 (2), 5 (1). Only recently reported from Kentucky (7), this distinctive snail is known from Harlan County only, though it doubtless occurs in Pike and Letcher counties as well. (2), 64 (1), 97 Triodopsis multilineata (Say) Collections: 20 (1), 26 (7), 55 (2). This large, beautifully banded species is known in Kentucky from Hickman, Fulton, Henderson, Bell, and Union counties. In dis- tribution it is restricted to low-lying, wet marshes, floodplains, and similar habitats. Allogona profunda (Say) Collections: 8 (1), 10 (7), 13 (3), 29 (1), 107 (2), 111 (2). Nowhere very abundant in Kentucky, this large polygyrid prefers deep leaf litter near decaying wood as habitat. 115 DiscussION Henderson’s (24) eastern land snail division includes all of the contiguous states east of the plains bordering the eastern slopes of the Rocky Mountains. That division includes the North- ern, Interior, Cumberland, Texan, and Aus- troriparian provinces. Most of Kentucky lies in the Interior Province; the southeastern corner belongs to the Cumberland Province. The principal gastropod affinities of the southeast- ern section of the state is with the Great Smo- kies-Blue Ridge sections of the Cumberland Province, with some segments of the fauna showing relationships with more easterly areas, ie., through Virginia and West Virginia. Ex- amples of the latter affinities include Philo- mycus togatus, P. venustus, P. flexuolaris, Pal- lifera dorsalis, Discus cronkhitei, Glyphyali- nia rhoadsi, G. inornatus, Mesomphix rugeli, Paravitrea multidentata, Stenotrema hirsu- tum, Triodopsis albolabris, and T. tridentata. Species demonstrative of the Blue Ridge- Great Smokies relationship include Carychium clappi, Cochlicopa morseana, Paravitrea sub- tilis, P. placentula, P. blarina, Glyphyalinia caroliniensis, G. rimula, G. praecox, Ventri- dens collisella, V. theloides, V. lawae, Zo- nitoides elliotti, Vitrinzonites latissimus, An- guispira mordax, Mesodon wetherbyi, M. normalis, M. kalmianus, M. appressus, Steno- trema evardsi, Triodopsis claibornensis, Poly- gyra plicata, and P. troostiana. Actually, the genus Polygyra is mainly a southern group with relatively few species extending their ranges into the Appalachians and a short dis- tance beyond, whereas Mesodon, Stenotrema, and Triodopsis were evolved in the southern United States (25). There are other segments of the Kentucky gastropod fauna, in addition to Polygyra (P. pustuloides, P. leporina), that show definite origins from southern areas. Included in this list are the following: Glyphyalinia cryptom- phala, G. sculptilis, Mesomphix globosus, Ventridens demissus, Gastrodonta interna, Stenotrema stenotrema, Mesodon rugeli, and Mesodon perigraptus. There is also a small segment of the Ken- tucky fauna that has its greatest affinities with more northerly faunas, including Carychium exiguum, the species of Vallonia, Succinea ovalis, Anguispira alternata (ss), Stenotrema 116 TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3-4) fraternum, Mesodon pennsylvanicus, and Triodopsis denotata. This is, of course, a sec- ondary relationship, compared with the pri- mary one with the southeast. Finally, a western—midwest relationship is demonstrated by the presence of Anguispira kochi, Mesomphix friabilis, Zonitoides lima- tulus, Rhabdotus dealbatus, Stenotrema leai, Triodopsis multilineata, and the primitive ge- nus Allogona. SUGGESTIONS FOR FURTHER STUDY The southeastern section of Kentucky and the section bordering Virginia and West Vir- ginia are nearly unscathed by gastropod col- lecting, particularly with regard to the Zo- nitidae. Likewise, extreme southwestern Kentucky, especially along the Mississippi Em- bayment, is deserving of some concentrated investigation. Collectors may be confident that work in these areas will disclose a relatively long list of terrestrial snails that have not been reported from the Commonwealth.

O’BARA Tennessee Cooperative Fishery Research Unit, Tennessee Technological University, Cookeville, Tennessee 38505 ABSTRACT The Big South Fork crayfish, Cambarus bouchardi, was originally known from 3 locations within the Roaring Paunch Creek system, Tennessee and Kentucky. As a result of the current survey, the species is now known from 21 locations, all within the Roaring Paunch Creek system. The species exhibited a plastic tendency in habitat selection, occupying both moderate and small streams with diverse substrate types. INTRODUCTION The Big South Fork crayfish, Cambarus bou- chardi Hobbs, is an epigean decapod endemic to the Roaring Paunch Creek system of Scott County, Tennessee, and McCreary County, Kentucky. The species was originally known from Perkins Creek (type-locality), Roaring Paunch Creek, and an unnamed tributary of Roaring Paunch Creek (1). Bakaletz and Bar- clay (2) reported the species from the middle and lower portions of Roaring Paunch Creek, McCreary County, Kentucky, and a tributary, Icecamp Branch, McCreary County, Ken- tucky. Due to its restricted distribution and possible threats from coal mining activities, Bouchard (3) considered C. bouchardi one of 14 species of jeopardized freshwater decapods in the United States. A lack of cover in the form of numerous rocks was believed to be the greatest limiting factor (3). Cambarus bouchardi is a member of the primitive, polytypic subgenus Veticambarus. All 3 species are endemic to the Cumberland Plateau Region (C. pristinus: Caney Fork sys- tem, Tennessee; C. obeyensis: Obey River sys- tem, Tennessee). A complete description of the 3 species can be found in Hobbs (1). The goal of this study was to determine the current distribution of C. bouchardi. Habitat requirements were also examined to a limited extent. Stupy AREA Sampling was conducted within the Cum- berland River system of Tennessee and Ken- tucky. The majority of streams sampled were part of the Big South Fork of the Cumberland River system, although adjacent systems, such as Marsh Creek, Murphy Creek, Trammel Branch, and Gum Fork, were also sampled. The Roaring Paunch Creek system origi- nates in northeastern Scott County, Tennessee, and flows northwesterly into the Big South Fork of the Cumberland River. The system is en- tirely within the Cumberland Plateau section of the Appalachian Plateau Physiographic Province. The Cumberland Plateau is under- lain by Pennsylvanian age shale, sandstone, siltstone, and coal. Soils are of the Ramsey- Hartsells-Grimsley-Gilpin type which are well drained and loamy. Most of the landcover is deciduous forest, with clusters of agricultural and mined lands (4). METHODS AND MATERIALS All collections were made with an aquatic dip net during the day. Sampling was con- ducted from March 1986 to June 1987, pri- marily during the period when males were of the first form (fall and spring). RESULTS AND DiscussION Cambarus bouchardi was collected at 21 lo- cations, all within the Roaring Paunch Creek system (Table 1). Order Creek was the only stream sampled within the Roaring Paunch Creek system that did not contain C. bou- chardi. Other sites sampled adjacent to the Roaring Paunch Creek system did not yield C. bouchardi. Similar distributional trends have been reported, confirming that the species is currently restricted to the Roaring Paunch Creek system (1, 2, 5). Within the Roaring Paunch Creek system, the Big South Fork crayfish inhabited a wide variety of habitats. At the stream’s confluence 117 118 TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3-4) TABLE l.

Specimens were collected from boulder runs, silt inundated pools, and vegetative clumps in a heavily silted stream. This is contrary to habitat preference reported by Bouchard (3), in which large rocks were considered a limiting factor. It appears that C. bouchardi exhibits plasticity in its habitat se- lection within the small- to moderate-size streams of the Roaring Paunch Creek system. This plasticity in habitat selection appears to have enabled C. bouchardi to exist in severely degraded sections of the Roaring Paunch Creek system. Coal mining activities, especially sur- face mines, have adversely affected most of the tributaries, as well as Roaring Paunch Creek. Although C. bouchardi has survived under these adverse conditions, concern should be given if new and possibly degrading activ- ities are considered. The restricted range of C. bouchardi may be explained by the theory that the Cumber- land Plateau was the center of origin for the genus Cambarus. Hobbs (6) proposed this due to the presence of the endemic primitive cray- fish C. pristinus, C. bouchardi, and C. obey- ensis. If C. bouchardi evolved in the Roaring Paunch Creek system, it appears that the species has been naturally isolated by the Big South Fork of the Cumberland River. This is sup- ported by the greater relative abundance of the Big South Fork crayfish in upstream sec- tions and its absence in the Big South Fork of the Cumberland River in the vicinity of the confluence with Roaring Paunch Creek.

Potts, AND J. G. RODRIGUEZ Department of Entomology, University of Kentucky, Lexington, Kentucky 40546 ABSTRACT Eggs, immature stages, and adults of Tetranychus urticae possess volatile kairomones that are quantitatively determined. Teneral and ovipositing females are the chief sources of these chemicals which are solvent extractable and which strongly attract 3 species of predatory phytoseiid mites, Phytoseiulus persimilis Athias- Hermiot, Neoseiulus fallacis (Garman), and Typhlodromus occidentalis Nesbitt, in that order. In choice- tube assay, extracts of ovipositing prey females or of fresh material (killed by freezing) were highly attractive to P. persimilis in concentrations as low as 50 wg. The predator responded rapidly (within 15 min) to the attractant in the choice tube. INTRODUCTION Phytoseiid mites play an important role in the pest management of tetranychid mites in various agroecosystems. Phytoseiids are ag- gressive predators, although some genera or species groups are general feeders, feeding on such alternate foods as small arthropods, nema- todes, pollen and fungi, as noted in the review by McMurtry and Rodriguez (1). Several investigators have studied phyto- seiid behavior but only in recent years have these studies focused on the chemical ecology aspects of food finding. For example, conclu- sive evidence for an attractant, ie., a kairo- mone, was first presented by Hislop and Pro- kopy (2), who showed that filter-paper disks treated with extracts from silk and associated feces of Tetranychus urticae Koch are attrac- tive to Neoseiulus (=Amblyseius) fallacis (Garman). Sabelis et al. (3, 4) also demonstrat- ed arrestment responses of Phytoseiulus per- similis Athias-Henriot to odor gradients of T. urticae. The kairomone(s) responsible for dis- tant attraction of P. persimilis is present on the eggs and feces of the spider mites as well as on the exploited leaf surface, but not on the webbing produced by the mites. According to de Moraes and McMurtry (5), kairomone(s) responsible for arrestment of P. persimilis was present in extracts from adults, eggs, and web- bing plus excreta of Tetranychus evansi (Bak- er and Pritchard) and T. urticae. However, in ' Present address: Acarology Division, Agriculture Fac- ulty, Cairo University, Giza, Egypt. work reported by Dong and Chant (6), P. per- similis was attracted to the adult and webbing of Tetranychus pacificus McGregor and not to prey eggs, larvae and protonymphs. Researchers have utilized several methods to assay tetranychids or their products and ex- tracts for kairomones. For example, a single choice observation chamber has been used (2) as has a Y-tube olfactometer (8, 4). The objec- tives in our study were to challenge species representives of three phytoseiid genera, namely P. persimilis, N. fallacis, and Typhlo- dromus occidentalis Nesbitt, with all stages of the prey T. urticae using a two-choice tube technique developed in this laboratory. This would also permit us to examine the behavior of the 3 species under comparable conditions. MATERIALS AND METHODS STOCK CULTURES Phytoseiulus persimilis, N. fallacis and T. occidentalis were taken from a stock colony maintained on T. urticae which was cultured on bean plants (Phaseolus vulgaris L.) in the Acarology Laboratory at the University of Kentucky. Females of N. fallacis and T. oc- cidentalis were starved for 5-6 hours before being used in the experiments. However, this procedure was unnecessary for P. persimilis (5, 6).

The weights were obtained for mites at every stage and the mean weights were related to numbers of mites in each de- velopmental stage to give a fresh weight of mite tissue of 50, 100, 150, and 200 ug (Table 1). The weight/number relationship of all stages of T. urticae was used for each choice test for fresh material or extract of an organic solvent. Tetranychus urticae eggs (2-3 days old) were removed from bean leaves by shaking the leaves over black filter paper and the eggs were in- dividually collected with a fine tipped brush. This method was used, instead of collecting the eggs directly from the leaves, to avoid con- tamination by silk (which sticks to the egg), fecal matter or other materials on the leaf. Active stages of T. urticae were sampled by shaking infested bean leaves over black plastic sheeting in a petri dish, killed by freezing, and collected with a fine tipped brush. KAIROMONE EXTRACTION Ethanol, hexane, ether and water were used as solvents for kairomone extraction. The ap- propriate number of T. urticae for each de- velopmental stage (depending on weight/ number relationship) was placed into a 5 ml beaker with 1.0 ml solvent. The mites were removed by filtration after 5 minutes and the filtrate was placed into micro cells” containing a filter paper disk (1.0 em diameter). The sol- vent was then evaporated at ambient condi- tions. The evaporation time varied among the solvents. Ether and hexane required 30 min- utes, ethanol required 1.5-2 hours while water required 6-8 hours. The control was prepared 2 Disposo-Tray, Linbro Chemical Company, Inc., New Haven, Connecticut. by treating a filter paper disk with solvent mi- nus mite extracts. A preliminary test, with the adult females of N. fallacis, was conducted to determine the best solvent to be used in the extraction of kairomones from ovipositing adult females of T. urticae. Extracts were tested for attractive- ness to the predators by the choice-tube tech- nique (Table 2). CHOICE-TUBE TECHNIQUE The choice-tube technique used in this test was originally used by Winston (7), modified by Jalil and Rodriguez (8) and Wicht et al. (9) to test the attraction of Macrocheles muscae- domesticae to substances present in the house fly, Muscae domesticae, and used by Rodri- guez et al. (10) to study the attraction or re- pellency of T. urticae and T. turkestani Uga- rov and Nikolski to water-soluble extracts from strawberry foliage. Five adult females of the phytoseiid pred- ators of standard age (3-5 days after their final molt) were introduced into each end of the choice tube and the ends closed by rubber stop- pers. The fresh related weight/number of each prey stage was put into the tube cup (test) and fixed to the choice tube with Scotch Tape®. An empty cup (blank) was fixed to the other side. TaBLE 2.

FALLACIS Neoseiulus fallacis was significantly attract- ed to both fresh and ether-extracted materials of all stages of T. urticae (Figs. 3, 4). A weight increase of all stages of T. urticae material resulted in increased attraction. The greatest attraction was recorded generally at 15 min- utes for all stages of T. urticae and all con- centrations. No significant responses were re- corded for ether extracts of 50 wg of larvae, deutonymphs and adult males at any time pe- riod, and no significant responses were ob- served for any stage of T. urticae or extract concentration level at 60 minutes. No attrac- tion was observed in the control. ATTRACTION RESPONSE OF T. OCCIDENTALIS Typhlodromus occidentalis showed a posi- tive significant response to either fresh or ether- extracted materials of all T. urticae stages. The attraction response increased concomitantly with weight (concentration) of T. urticae stages (Fig. 5), and the greatest response values were recorded at the first 15-minute count (Figs. 5, 6). No significant responses were recorded at any time when fresh larvae and adult males were used at the 50 wg concentration level or for extractions of 50 ug of eggs, larvae, deu- tonymphs and adult males. No significant re- sponses were recorded at 60 minutes for any mite stage or extract concentration. DiscussION Experiments utilizing two-choice-tube tests illustrated that eggs, immature stages and adults of the twospotted spider mite possess volatile chemical(s) which attracted the three species of phytoseiids. We have demonstrated that these chemicals (kairomones) are attractive quantitatively to the predators and can be ex- tracted by organic solvents. The adult teneral and ovipositing females of T. urticae are the most important sources of the kairomones fol- lowed by eggs, adult rales, and then the im- mature stages. Increased weight increment in spider mites (concentration) resulted in in- creased attraction response. The 3 phytoseiid predators demonstrate a strong attraction re- sponse to the volatiles that emanate from the test source. Phytoseiulus persimilis is strongly attracted to either fresh material or extracts of the various stages of the prey followed by N. fallacis and T. occidentalis. The choice-tube assay produced rapid re- sults indicating that the kairomone(s) tested were relatively volatile as these odors equili- 125 PHYTOSEIID PREDATION ON SPIDER MitEs—Afifi et al.

Positive responses were obtained within 15 minutes as indicated in Figures 2, 4, 6 and, although data are not shown in this report for the sake of brevity, our recorded data show that the lower weight or concentration levels, usually took 30-45 min to elicit an attraction response, however weak, from the predator. Later, the predator moved randomly about the tube as was the case in the control. Eggs of T. urticae proved to be a good source of kairomones, but the eggs may have acquired the kairomones as contaminates from webbing or feces. Jackson and Ford (11) found that when T. urticae egg kairomones were extracted away with distilled water, P. persimilis consumed about 50% the number of unwashed eggs. Also, T. urticae eggs which were deposited on glass plates apparently did not have kairomones (3, 4). However, T. pacificus eggs, larvae and pro- tonymphs did not attract P. persimilis (6). Although the immature stages of T. urticae were a source of kairomones, our data (un- published) showed that deutonymphal and teneral stages were more attractive than the protonymphal and larval stages to the three phytoseiid species. Adult males gave a response similar to that of the deutonymphal female stage. Our results agree with those of Sabelis et al. (3, 4) who used the Y-tube olfactometer and reported that all feeding stages of T. ur- ticae produced kairomones. Phytoseiulus per- similis, however, did not show significant pref- erence for disks treated with extracts of T. evansi larvae, protonymphs, deutonymphs and adult males at any concentration, (5), nor were they attracted to T. pacificus eggs, larvae and protonymphs (6). Our data strongly indicate that the adult teneral and ovipositing females of T. urticae are a strong source of kairomones. Adult ovi- positing females elicited higher attraction re- sponses than the teneral females when either fresh or extracted material was used. Our re- sults generally support those of Sabelis et al. (3, 4), who reported that P. persimilis response to pre-oviposition females of T. urticae was not matched by the response of any other stage. Kairomone chemistry apparently differs from one prey species to another, and the kai- romone of the prey species may attract one predator species but not another. Hoy and Smi- lanick (12) found that T. occidentalis females TrANs. KENTUCKY ACADEMY OF SCIENCE 49(3-4) are arrested in searching behavior in webbing produced by T. urticae but only slightly by webbing of Panonychus ulmi. Sabelis and Van de Baan (13) showed that P. persimilis and T. occidentalis reacted positively to the odor em- anating from bean leaves infested by T. urti- cae, but they did not react to the air stream blown over apple leaves infested by P. ulmi.

INTRODUCTION During the spring and early summer of 1987, the author conducted several field exercises for the purpose of collecting a variety of mostly fleshy fungi, principally in the eastern sections of the state. Included in these collections were representatives of 15 genera and 16 species of ascomycetes and 6 genera and 6 species of myxomycetes. Since there are very few pub- lished reports for these and other fungi in Ken- tucky, it is appropriate to publish these results. The principal features utilized in making diagnoses were standard ones of general mor- phology, color, details of subterrranean parts, microscopic anatomy of spores and other parts, chemical reactions, and habitat. COLLECTING SITES Most of the specimens were secured from 3 main locations. 1. A “knob” hill area, 6.6 km east of Berea off SR 21, in the vicinity of Indian Fort The- atre, Madison County, Kentucky. The flat- ter-lying land around the entrance to the area has relatively deep, lignin-rich soil and an open mixed forest of hickories (princi- pally pignut), maples, ashes, and Virginia pine; willows, hackberry and sweetgum oc- cur along two small creeks. On the steep knobs above the theatre area, crisscrossed by a maintained hiking trail, are heavy growths of tulip poplar, sugar and red ma- ples, hickories, oaks, and some beech. On the drier uplands there are abundant stands of Virginia pine and cedar. 2. Big Hill, a historically important landmark knob 16.4 km south of Kingston on U.S. 421, extreme southeastern section of Madison County, Kentucky. This is a very steep hill with considerable deep, lignin-rich soil and much fallen woody debris, rotten logs, and moss and ferns. Tulip poplars, maples and hickories dominate the woodlands with scattered stands of Virginia pine and east- ern hemlock. 3. Red River Gorge area, from the Nada Tun- nel (SR 77) to a point 6.0 km eastward. This is a mixed mesophytic section of Daniel Boone National Forest in Powell County, Kentucky. The soil is rich in lignin beneath a canopy of tulip poplar, maples, oaks, rho- dodendron, white pine, eastern hemlock, many other tree species and myriad small woody plants in the undercover. Moss and ferns abound. RESULTS ASCOMYCETES PEZIZALES. Five genera of these interesting cup fungi were collected. Galiella rufa (Schw.) Nannf and Korf. Sparse fruitings were found on soil-covered wood be- neath hickories and pines in the lowlands around the Indian Fort Theatre location on 9 September 1987. The fertile surface of the fun- gus was reddish-brown and the outside of the cup was heavily covered with black “hairs”. The species is illustrated (plate 56) by Seaver (1) as Bulgaria rufa. I follow Pfister (2) in assigning the name. Sarcoscypha occidentalis (Schw.) Sacc. Hundreds of specimens of this pretty little fun- gus were observed on decaying wood, 27 June 1987, at the Big Hill location. The species was discussed by Seaver (1) as Plectania occiden- talis and placed in Sarcoscypha by Denison (3) and Pfister (2). Sarcoscypha conninea (Scop.) Sace. Many specimens were found on sticks buried in mud- dy soil on the Kentucky River bluffs near the 128 FUNGI IN EASTERN KENTUCKY—Branson I-75 bridge, Madison County, Kentucky, 2 July 1987. This was rather late in the season for this species, but since the early summer was cool and wet the occurrence was not unexpected. The fungus is illustrated in Seaver’s (1) plate 19. Denison (3) placed the species in Sarco- scypha. Microstoma fluccosa (Schw.) Raitviir. Many specimens were found on dead twigs at the Big Hill location, 27 June 1987. This shaggy, red- cupped fungus was illustrated by Seaver (10 on plate 20). Urnula craterium (Schw.) Fr. Two speci- mens were found on the ground under pines and hickories at the Indian Fort Theatre low- lands, 9 September 1987. This was an unusual fruiting period for the species (4). Cheilymenia coprinaria (Cooke) Boud. Thousands of specimens were found on semi- dry cow dung at the Eastern Kentucky Uni- versity dairy farm, Madison County, Ken- tucky, 19 July 1987. Widely distributed in North America and Europe (1), there are few reported records for the species in our area. Cheilymenia michiganensis Povah is a syn- onym (2). HELOTIALES. Representatives of 4 genera were collected. Chlorociboria aeruginascens (Karst.) Fenn. Numerous specimens were found on rotten eastern hemlock logs on a hillside above the Nada Tunnel at the Red River Gorge site, 9 June 1987. This small to minute fungus is wide- spread in America and Europe (5). Bisporella citrina (Batsch) Korf. and Carp. Abundant specimens were secured from dead twigs and leaves on the ground in a low-lying swale, 5.3 km east of Nada Tunnel, 9 June 1987. This bright yellow fungus is discussed by Seaver (5) as a Helotium and illustrated on plate 104. Leotia lubrica (Scop.) Pers. Several speci- mens were found in the same locality as the last species, on dead leaves and twigs. The species is illustrated on Arora’s (4) color plate 215. Leotia viscosa Fries. Six specimens were re- moved from decaying maple leaves at Levi Jackson State Park, Laurel County, Kentucky, 3 December 1978. Arora (4) presented a color illustration (plate 215). Spathularia flavida Pers. A few specimens were found growing on much-decayed wood 129 at the Indian Fort Theatre locality, 15 July 1987. Seaver (5) considered the species to be a synonym of S. clavata (Schaeff) Sacc., but Arora (4) indicated the reverse. HELVELLACEAE. One genus and 2 species were collected. Helvella crispa (Scop.) Fr. One beautiful ex- ample of this elfin saddle was found growing at the base of a Virginia pine, 15 July 1987, in the flatlands below Indian Fort Theatre. Lin- coff (6) presented a color illustration. Helvella elastica Bull. One specimen was found growing on the ground below a mixture of sugar maples and eastern hemlocks, 9 June 1987, near the eastern end of Nada Tunnel at the Red River Gorge locality. The ellipse- shaped spores each had a large, centrally lo- cated oil droplet. MORCHELLACEAE. One species was col- lected. Morchella angusticeps Pk. A single speci- men of this black morel was secured from the edge of a grove of young tulip poplars above the Natural Bridge State Park Lodge, Powell County, Kentucky, 8 May 1987. Sundberg and Richardson (7) reported and color-illustrated the species from Land Between the Lakes, western Kentucky. PYRENOMYCETES. Representatives of 4 genera were collected. Cordyceps capitata (Holmsk.) Link. Two specimens were found growing on under- ground fungi beneath tulip poplars 0.8 km above Indian Fort Theatre, 15 July 1987, a typical habitat for this species (8). Cordyceps militaris (L.) Link. A single spec- imen was found on a partially buried insect larva at a site 7.0 km west of Richmond via Barnesmill Road, Madison County, Kentucky, 23 June 1987. The marginal forest along Silver Creek consisted principally of sycamore, ma- ples, willows, black walnut and hackberry. This is a provisional diagnosis (see 8, 9). Xylaria hypoxylon (L.) Grev. Many speci- mens of this easily recognized fungus were collected from a moss-covered, burn-scarred log on a hillside above Nada Tunnel in the Red River Gorge locality (9 June 1987) and from the burned, inner surface of an old whiskey barrel at Deacon Hills Estates, Madison Coun- ty, Kentucky (22 July 1987). Ustulina deusta (Fr.) Pers. Several large col- onies of this encrusting fungus were found on 130 burned logs at the Big Hill locality, 3 July 1987. The spore print was very black and the large perithecia had their pores immersed in light- colored tissues. Hypoxylon fragiforme (Pers.) Kickx. Two large populations were found at the Big Hill locality on burned logs (2 July 1987) and one population was observed on a standing beech stump 5.8 km north of Richmond, Madison County, Kentucky, just off SR 60, 3 November 1986. MyYXOMYCETES The occurrence and distribution of slime molds in Kentucky is very poorly documented. Representatives of 6 genera are reported here. Arcyria incarnata (L.) Welt. A nicely dif- ferentiated colony was found on a wet log at the Indian Fort Theatre locality, 3 June 1987. Brefeldia maxima (Fr.) Rost. A large colony was found on a standing dead ash tree on the campus of Eastern Kentucky University, Rich- mond, Madison County, Kentucky, 28 June 1985. Ceratiomyxa fructiculosa (Mull.) Mac. Two colonies of this easily recognized slime mold were found, one on a dead hackberry log in Deacon Hills estates, Richmond (19 June 1987), and one ona dead pignut hickory at the Indian Fort Theatre lowlands (15 July 1987), both in Madison County. The species was previously reported from western Kentucky (7). Leocarpus fragilis (Dicks.) Rost. A colony of yellow-brown, insect-egg-like cases was found on very rotten wood at the Indian Fort Theatre site, 15 July 1987. Microscopic ex- amination demonstrated the typical three-lay- ered arrangement of this slime mold (6). Lycogala epidendrum (L.) Fr. A small col- ony of this interesting slime mold was found on a dead, barkless tree trunk 7.0 km west of Richmond, Madison County, Kentucky, TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3—4) Barnesmill Road, 23 June 1987. The species has also been reported from Land Between the Lakes in western Kentucky (7). Stemonitis splendens Rost. One small col- ony was found on dead wood 0.3 km above Indian Fort Theatre (15 July 1987), a site heavily shaded by tulip poplars and beeches. Sundberg and Richardson (7) reported the re- lated form S. axifera (Bull.) Macbr. from Land Between the Lakes. This slime mold is one of the most common and is worldwide in distri- bution.

FREY AND Davip E. Lecc! Community Research Service, Kentucky State University, Frankfort, Kentucky 40601 ABSTRACT Ten media were compared for isolating fungi from stored maize, Zea mays L., in Kentucky. Laboratory tests indicated that Czapek-Dox solution containing 20% sucrose and filter paper soaked with sterilized distilled water were among the least species-restrictive, easiest to prepare, and most economical to use for isolation of fungi. Additional experimentation suggested that 25°C was a better incubation temperature than 30°C and that colony counts of the species present were equivalent when cultured in complete darkness or under a 12:12 (L:D) photoperiod. INTRODUCTION Isolation techniques for fungi can be species specific. Species selectivity is preferred when recording the presence and quantity of a given fungus. It is, however, of little use in survey- oriented work where detection of the widest possible species range is desired. Many techniques for fungal isolation and culture are available (1) but few have been designed for extensive survey work in post- harvest stored grains (2). Notable exceptions are those of Mills et al. (2) who designed, tested, and selected mycological isolation techniques for surveying the fungi of stored rapeseed, Brassica napus L., in western Canada. Isolation media have also been tested for determining the “numbers and kinds” of fungi associated with stored maize, Zea mays L. (3). These, however, were used with the dilution- plating technique which later was found to be not as effective for detecting the presence of fungi as the whole-kernel plating technique (4). These results were supported by Pixton et al. (5) who used cornmeal agar and plain agar, which Christensen did not use in his earlier work (6, 4, 3). In contrast, Mills et al. (2) made use of the whole kernel plating technique. It is well known that environmental condi- tions can significantly affect fungal growth (4). However, experiments conducted by Mills et al. (2) were carried out under one temperature (25°C) in complete darkness without docu- menting the number of kernel surface contam- ' Current address: Department of Plant, Soil and Insect Sciences, P.O.

Chris- tensen (4) used a 30°C incubation temperature because it promoted “a more rapid appearance of most of the common species of the Asper- gillus glaucus, A. candidus and A. flavus groups than incubation at 25°C.” He made no mention of or placed any importance on photoperiod. Information concerning the amount of surface contaminants and degree of infestation is use- ful when determining the microbial contam- ination of the grain. The purpose of this paper is to compare 10 isolation media, using the whole-kernel plating technique, in order to determine which media would be most suitable for survey work on stored maize in Kentucky. In addition, 2 cul- turing temperatures, 2 photoperiod regimes, and 2 grain surface treatments were tested for possible influence on number of colonies per species. MATERIALS AND METHODS Experimental maize was grown, combine- harvested, and shelled in 1984 and stored on the University of Kentucky Coldstream Farm. Approximately 25.5 kg was obtained in No- vember of 1985, taken to Kentucky State Uni- versity, and placed in cold storage prior to experimentation. Experimental maize consist- ed of broken, cracked, and sound kernels, bits of maize cobs, stalks, and leaves, weed seeds, and a moderate to high infestation of Tribo- lium castaneum (Herbst) (i.e., more than 1 adult per 0.9 liter of grain). Kernels were care- fully scrutinized for cracks or broken parts with only sound kernels being used in this study. Kernels were placed in an environmental 131 132 chamber and held at 27°C, 80% RH until they had equilibrated to an 11% moisture content. Effect of Medium, Temperature, and Grain Surface Treatment Half of the experimental kernels were im- mersed in 1% sodium hypochlorite for 1 mi- nute, followed by 2 rinses in sterilized distilled water (sterilized maize); remaining kernels were not rinsed in sodium hypochlorite. The term “sterilized maize’ denotes surface dis- infection only. Eight sterile petri dishes were then set up for each of 10 media: plain agar (PA), filter paper + 4.5 ml of sterilized distilled water (FP), standard Czapek-Dox agar (CZA), filter paper + 4.5 ml of standard Czapek-Dox solution (CZFP), malt-salt agar (MSA) (4), filter paper + 4.5 ml of sterilized 7.5% NaCl solution (SFP), malt-salt agar with 18% NaCl (MSA18), filter paper + 4.5 ml of sterilized water con- taining 18% NaCl (SFP18), (Czapek-Dox agar with 20% sucrose (CZA20), and filter paper + 4.5 ml of Czapek-Dox solution containing 20% sucrose (CZFP20). Media choice was based on those used by Mills et al. (2) as well as the Czapek-Dox variants suggested by Christensen (4). Four petri dishes per medium received 10 kernels each from the sterilized treatment and the remaining 4 received 10 kernels each from the unsterilized treatment. Two petri dishes each of the sterilized and nonsterilized maize were then placed in a programmed environ- mental chamber set at 25°C, 12:12 (L:D), and 67% RH. The remainder were placed in a 30°C, 12:12 (L:D), 67% RH environmental regime. Photoperiod was produced with fluorescent lighting (GE F20T12-CW bulbs). The cultures were allowed to incubate for 4 days after which the number of colonies per species per kernel was counted. Cultures were then incubated 3 additional days after which time the number of colonies per species per kernel was again counted with the newly-emerged colonies being added to the previous count. Colonies per species were totaled over kernels per petri dish. Total number of colonies per petri dish were analyzed for possible effects of temperature, surface treatment, medium, and species that were present (independent variables) in a com- pletely randomized factorial analysis of vari- ance (7). Various combinations of the inde- pendent variables were also tested for a significant interaction effect on number of col- TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3-4) onies that were counted. Significance of each independent variable by itself (main effect) or in combination with one or more of the others (interactive effect) was determined by the F test (7). F values for main or interactive effects associated with probabilities that were less than 0.05 were considered significant. Although the complete analysis of variance was computed, the influence of main effects, the species X medium interaction and higher order inter- actions involving species and media were of primary interest; F and P values were reported for these factors only. Fisher’s protected least significant differ- ence (LSD) was used to separate mean colony responses of various levels of the main and interactive effects. The LSD for comparing mean colony counts of the main effects was based on the pooled experimental error. The LSD for comparing mean colony counts of the interactions was based on the pooled error of specific comparisons. Interactions were pre- sented graphically because, by definition, they appear as nonparallel responses of each level of one factor over all levels of the others (8). Effect of Photoperiod Regime The effect of complete darkness and 12 h of light on fungal colony count was assessed by setting up 4 petri dishes for each of 8 isolation media (PA, MSA, CZA20, FP, SFP, CZFP, and CZFP20), plating 10 maize kernels per dish, placing 2 dishes in complete darkness and 2 in a 12:12 (L:D) photoperiod. Both photoperiod regimes were held at 25°C and 67% RH. In- oculated media were allowed to incubate for 4 days after which the number of colonies per species per kernel was counted. Then the plates were incubated 3 additional days after which the number of colonies per species per kernel was again counted. New colonies were then added to those of the previous count. Colonies per species were totaled over kernels for each plate. Experimental maize was not rinsed in sodium hypochlorite. Total number of colonies per plate were ana- lyzed for the direct effect of photoperiod on fungal colony count. In addition, a potential influence of photoperiod on individual fungal species or on colony counts taken from specific media (interactive effects) was also investigat- ed. The experimental design was a completely randomized factorial analysis of variance (7). FuNGAL ISOLATION IN STORED MaizE—Frey and Legg 133 Taste 1.

RESULTS AND DISCUSSION Effect of Medium, Temperature, and Grain Surface Treatment Analysis of variance (Table 1) indicated that all main effects except temperature signifi- cantly influenced average colony counts. Also, the medium * species interaction and two 3-factor interactions involving medium and species were significant. The 4-factor inter- action was not significant. Comparisons between average colony count for various levels of the main effects showed that fungal infection was low relative to the amount of inoculum that was present (steril- ized maize mean = 0.388 + 0.062, nonsteril- ized mean = 1.722 + 0.147, n = 400). Analysis for species abundance indicated that 10 species were present and they occurred in varying amounts (Fig. 1). Aspergillus glaucus was the dominant species followed by A. flavus, Pen- icillium spp., and Mucor spp.; Fusarium spp., A. fumigatus, A. niger, and A. clavatus oc- curred in low but approximately equal num- bers while A. ochraceous and A. candidus were rarely observed. Aspergillus ochraceous and A. candidus were subsequently dropped from further analysis because their occurrence was so rare that it was not possible to determine the effect of each treatment and their inter- actions on these species.

These media were quite species selec- tive and effectively prevented all but A. glau- cus from growing. Since MSA18 and SFP18 did not meet the requirement of low species selectivity they were eliminated from further analysis. Analyses of the medium X species inter- action is comprised of eight sub-figures (Fig. 2). Each sub-figure represents a different species arranged from the most (upper left corner) to the least abundant (lower right corner). Media within a sub-figure are arranged by osmophilic properties (water binding potential) and me- dia-base within osmophilic property (agar or filter paper). PA and FP were the least os- mophilic (containing 0% water binding mol- ecules by weight) while CZA20 and CZFP20 were the most (containing 21.9 and 20.4% water binding molecules by weight, respectively). Standard CZA and CZFP, MSA and SFP had intermediate osmophilic properties (4.9, 3.4, 11.0, and 7.5% water binding molecules by weight, respectively). Specific comparisons first focused on testing for a possible filter paper-agar influence on mean colony counts; all possible comparisons between mean colony counts of media within species were then performed. Possible filter paper-agar influence on mean colony counts was tested within osmophilic groups for each species. Results indicated that just 4 of 32 com- parisons were significant and 3 of these con- cerned the MSA-SFP osmophilic group (Fig. 2). SFP significantly enhanced colony counts of A. glaucus but did not do so for Mucor or Fusarium spp. These data support the findings of Mills et al. (2) who showed that SFP pref- erentially selects for A. glaucus. These data also indicate that a general filter paper-agar influence on mean colony counts did not occur. All possible comparisons between the aver- age number of colonies per medium for each species were conducted in an effort to deter- mine those media that consistently promote the greatest colony growth over the species that are present (Table 2). Comparisons showed that no one medium significantly influenced mean colony counts for A. flavus, A. fumigatus, or Penicillium. Mean comparisons for the re- maining five species showed that SFP was ranked in the top group just once (for A. glau- cus) but was associated with the bottom group for the remaining 4 species. PA and CZFP were statistically ranked in the top group for isolation of 3 species (Fusarium, Mucor, and A. clavatus) but each fell into the bottom-most group of two species (A. glaucus and A. niger). CZA20 was ranked in the top-most group of three species but it fell into the bottom-most group of A. clavatus. CZA and MSA were each ranked in the top-most group in four species but both appeared to hinder colony growth of the most prevalent fungus (A. glaucus). CZFP20 and FP were ranked in the top-most group for isolation of four species; CZFP20 did not appear to hinder growth of A. glaucus but FP did. CZFP20 and FP each were ranked into the bottom-most group just once. While various isolation media had a wide- ranging impact on observed number of colo- nies across species, the performance of CZFP20 and FP most closely matched our stated char- acteristics of the ideal survey medium.

Also, CZFP20 and FP are on opposite ends of the osmophilic spectrum and if both are used on kernels drawn from the same sam- ple they would tend to complement each other. Thus, because of ease of preparation and os- mophilic properties, it is concluded that CZFP20 and FP generally were the least species specific and enhanced colony growth more than the other isolation techniques. Analysis of the temperature < medium x species interaction (Fig. 3) indicated that most species were either unaffected by temperature (Mucor, Fusarium, A. fumigatus, A. niger, and A. clavatus) or growth was enhanced at 25°C on certain media (A. glaucus and Peni- cillium). The exception, however, was A. fla- vus for which enhanced growth (colony pro- duction) occurred at 30°C on CZA, CZA20, and CZFP20. These data support the findings of Christensen and Kaufmann (9) and Christen- sen (10) who reported that optimal growth of A. glaucus and A. flavus are 24 and 36-38°C, respectively. Optimum temperatures for Pen- icillium growth is species dependent but it gen- erally occurs at temperatures less than 30°C. These data suggest that while no one incuba- tion temperature was ideal for growing all fun- gi, growth at 25°C was as good as if not better than that at 30°C except for A. flavus. The sterilization regime X media x species interaction (Fig. 4) indicated that the level of infection was quite low for all species except A. glaucus and Fusarium and that the increase in Fusarium colonies on MSA and CZFP20 for the sterilized maize was the primary cause for the interaction. The reason that Fusarium was more prevalent in the sterilized maize may be Trans. KENTUCKY ACADEMY OF SCIENCE 49(3-4) due to an antagonistic effect of one or more of the other fungi on Fusarium. Experiments conducted by Chang and Kommedahl (11) showed that Fusarium spp. growth was se- verely inhibited by Chaetomium globosum and Bacillus subtilis. Moreover, they found that Fusarium roseum growth was inhibited by both Aspergillus flavus and Penicillium spp., 2 prevalent fungi in this study. Effect of Photoperiod Regime Analysis of variance indicated that photo- period did not affect general colony counts, counts from a specific fungus (photoperiod x species interaction), counts from a given me- dium (photoperiod x medium interaction), or a specific fungus growing on a certain medium (photoperiod X species X medium interac- tion) (Table 3). These results indicate that, for the species present, colony growth under a 12: 12 (L:D) photoperiod is equivalent to that un- der a 24 hr scotophase and suggest that pho- toperiod may be unimportant to growth of fun- gi associated with stored maize. This was expected since fungi are achlorophyllus. ACKNOWLEDGMENT This investigation was supported in part by a USDA/CSRS grant to Kentucky State Uni- versity under agreement KYX-10-87-06P.

Sci., 49(3-4), 1988, 140-142 NOTES Bat Notes from Eastern Kentucky—A fall mist-netting investigation in eastern Kentucky produced the following noteworthy results. Monofilament mist-nets were set at 2 sites over the Poor Fork of the Cumberland River: 1 in Harlan County 1.5 km north of Cumberland, the other site approximately 8 km upstream from the first in Letcher County. A set of 3 or 4 nets was placed at each station for 2 nights (14 and 15 October, 1987), and tended until mid- night when temperatures dropped to about 4°C, The 2 stations in 2 nights yielded 60 bats of 5 species. The majority of red bats, Lasiurus borealis, captured (29 of 31) were males, but 6 others escaped before their gender was identified. All bats were marked by placing a small nail-polish spot on a wing, but only | red bat was captured twice. We also captured 20 silver-haired bats, Lasionycteris noctivagans; the sexes were equally represented. Unlike the ubiquitous red bat, the silver-haired bat is an uncom- mon species in Kentucky. One of us (H.D.B.) had previ- ously collected over 200 bats, using mist-nets set over Com- monwealth streams in summer, but had never collected a silver-haired bat until this study. Two previous nights of mist-netting in July 1987 at these same 2 sites on the Cumberland River did not disclose silver-haired bats. It is likely that the species was in migration from its northern breeding grounds to its winter range. We have found a few specimens hibernating in limestone caves in eastern Kentucky. Winter surveys by JRM recorded the species from caves in Carter, Jackson, Lee, Pulaski and Rockcastle counties, usually only a few individuals from crevices or found hanging in the cold areas of the caves. Although there is evidence of sexual segregation during summer (Barbour and Davis, Bats of America, Univ. of Kentucky Press, 1969), the sexes apparently sometimes migrate together. At our upstream station on the second night of netting, we caught 15 silver-haired bats (8 females and 7 males). Multiple captures of 2 or 3 silver-haired bats occurred several times and both sexes were usually rep- resented. A single specimen of the federally endangered gray bat, Myotis grisescens, was also captured at the downstream site in Harlan County. This young male was taken in a net set at water level. This is only the third record of this species in eastern Kentucky and the first collected foraging over a stream. The other 2 were recorded in caves in Carter and Lee (Davis, Bat Res. News, V 10:29-30, 1969) counties almost 2 decades previously. Since M. grisescens uses caves in both summer and winter, this animal was probably enroute to its winter hibernaculum. The only gray bat hibernaculum known in Kentucky is in Edmonson County about 300 km west of our sites. However, several smaller colonies of gray bats are known to hibernate in abandoned mines and caves in eastern Tennessee (Currie, USFWS, pers. comm., 1987). There is a possibility that gray bat hibernacula remain undiscovered in caves of the Newman Limestone on Pine Mountain. The other 2 species captured during the October netting study were the big brown bat, Eptesicus fuscus, and the little brown bat, Myotis lucifugus. Each species was rep- resented by 2 males. We increased our number of captures from 14 to 28 on the second night at the Letcher County station by moving several hundred meters upstream. Our nets at the Harlan County station, which remained at the same site both nights, caught only half as many bats the second night. We appreciate the help of J. A. Roscher, R. M. Morris and W. D. Hendricks, who assisted with the difficult task of mist-netting on these cold evenings.—Hal D.

Griseb. in Kentueky—Alligatorweed (Amaranthaceae), a native flowering plant of eastern South America, was first reported in the southeastern United States from Florida in 1894 (Robertson, J. Arnold Arb. 62:267-313, 1981). Spreading rapidly over much of the southern Atlantic and Gulf Coastal plains, it has become a serious pest in many southern waterways from South Carolina to Texas (Mears, Proc. Acad. Nat. Sci. Phil. 129:1-21, 1977; Spencer and Coulson, Aquatic Bot. 2:177-190, 1976). Infestations have also been reported from Virginia, North Carolina, Ten- nessee, Arkansas, and California (Weldon, USDA-ARS, Crop Res. Div. Ser. 33-60, 41 pp., 1960). This note reports the species from the Tennessee River shoreline in western Kentucky and indicates its weedy potential there. Alligatorweed is a perennial, aquatic herb with erect or prostrate stems and hollow, buoyant internodes (Fig. 1). It is primarily a floating plant but may be completely terrestrial in moist soil or rooted along watercourse margins with branches extending outward for 15 m or more on the water surface and for up to 1 m downward into the water; roots develop at most nodes and lateral shoots from many, resulting in extensive mats. The flowering head is a globose spike of 10-20 white flowers but viable seeds are rarely, if ever, produced in the United States. Instead, reproduc- tion is vegetative, by fragmentation, and each node is capable of producing a new plant. Classed as a weed because of its competitive advantage over native plants, few species can compete successfully with it. Also, it is extremely difficult to control due to high tolerance to herbicides and great reproductive capacity. Even mechanical destruction, without removal, results in proliferation; however, biological (insect) control is prov- ing effective (Reimer, Introduction to Freshwater Vege- tation, AVI Publ. Co., Westport, Conn., 1984). The presence of Alligatorweed in most waterways is undesirable for a number of reasons. Mats impede water 140 141 Fic. 1. Trigg County, Kentucky (APSC). movements, restrict traffic on navigable waterways, and hinder fishing and recreation. Also, they block drainage and irrigation channels, thus increasing the threat of flood- ing, and cause public health problems by increasing mos- quito breeding areas and water pollution from decom- position. Alligatorweed is one of several aquatic pests in Tennessee River impoundments of northern Alabama, and that waterway has provided a migratory route northward. Wofford, Webb, and Dennis (Castanea 42:190-193) first Portion of an Alligatorweed plant, drawn by Treva Myatt from Chester 87-704, collected 25 August 1987, reported the alligator weed from the lower Tennessee Riv- er drainage (Henry Co., Tennessee) in 1977 and herbarium specimens at APSC, TENN, and VDB, representing later collections, now voucher its presence from several sites and counties there. The only mention of the species in Kentucky botanical literature is that of Beal and Thieret in their recent account of Kentucky wetland plants (Kentucky Nat. Pres. Comm., Sci. and Techn. Ser. 5, 1986). They reported a persisting 142 stand ina Knox County (southeastern Ky.) ditch. However, I have found it to be well-established at several points along the eastern shoreline of Kentucky Lake, the most downstream impoundment of the Tennessee River, in Lyon and Trigg counties, mostly in shallow water or on mud along bays and inlets or in small, shoreline ponds resulting from wave-created dams. Since Ellis, Wofford, and Chester did not include it in their list of area plants (Castanea 36:229-246, 1971), move- ment into western Kentucky may be recent.

ABSTRACT Effects of Mg?+ and EDTA on microsomal UDP-glu- curonosyltransferase activity. R. F. VOLP and CHARLES DIETSCH*, Chemistry Dept., Murray State University, Murray, KY 42071. The effects of UDP-glucuronic acid (UDPGA), EDTA, and Mg?* concentrations on UDP-glu- curonosyltransferase activity were studied in vitro. Incu- bations of rat liver microsomes with 0.5 mM 4-methylum- belliferone were conducted at 37°C for various times and stopped with 0.5 M HCIO,. The mixtures were centrifuged and the supernatant analyzed by high performance liquid chromatography (cyano column). The area of the 4-meth- ylumbelliferyl glucuronide (MUG) peak was an index of enzyme activity. Rate of MUG production depended on UDPGA concentration (0.1-3.0 mM). Mg?* (0-20 mM) and EDTA (0-10 mM) both affected the reaction rate. MUG production was highest at 5-10 mM Mg?* and 1.0 mM EDTA. These results define incubation conditions for further studies of the Mg?* dependence of the enzyme. Trans. Ky. Acad.

Sci., 49(3-4), 1988, 145-150 PRESIDENTIAL ADDRESS WILLIAM HETTINGER Dr. William Hettinger 1988, President, KAS As has been pointed out by our Presidents over the years, it is customary for the incoming President to address the members in this first or spring newsletter of the Academy. Somehow this conjures up images of spring rites, flowers, new green grass and such other pleasant thoughts associ- ated with springtime. However, as I sit here in my office on a cold, blustery, gray winter's day in January, with the temperature approaching 0 degrees Fahrenheit, I must confess, I have difficulty getting into the spirit of such thoughts. Only the pervading thought that perhaps I might somehow slip down to Florida for a few days in late Feb- ruary, helps me get into the proper frame of mind for this letter. As is also customary for the President, this letter enables me to comment on the accomplishments of the Academy over the past year, the highlights of the annual meeting, 145 146 to express appreciation for all of the many accomplish- ments and contributions of so many dedicated people, and especially your past President, Larry Giesmann, officers and board members of the Academy, and Joe Winstead and Charles Kupchella and co-workers who arranged for and provided such a fine outing for our annual meeting. It also gives the incoming President the opportunity to set some new goals and objectives for the coming year. The Academy continues to grow and prosper under the energetic leadership of a continuing string of most capable Presidents, stretching back, at least, as far as my memory serves me, over the almost eleven years of my residence in Kentucky, and membership in the Academy. These Presidents, without exception have been outstanding, and the growth in membership, the activities of the Academy, and its present financial status, all are testimony to their contributions. Before I review the progress and accomplishments of the Academy for the past year, and the contribution of so many, however, I'd like to reflect a bit on the various goals, objectives and purposes of the Academy as they have been expressed over the years, as they are expressed today in these more recent accomplishments, and as they impact on my goals for the coming year, and those longer range goals which others coming after us will form and seek to achieve. The Academy means many things to each of us, and undoubtedly each of these things may be more important to one individual member, and less to another, or be dif- ferent, one from another. The objectives and purpose of the Academy, as set forth in our Constitution in early discussions at the onset of the Academy, and even in our latest brochure, is as follows, and I quote: “The objectives of the Kentucky Academy of Science are to encourage scientific research, to promote the diffusion of scientific knowledge, and to unify the scientific interests of the Commonwealth of Kentucky. Note that scientific interests can be interpreted to encompass not only academic interests, but industrial and govern- mental interests as well. The Kentucky Academy of Science appears to serve its members and the citizens of Kentucky through activities in harmony with its objectives. Specifically, its aims are: (1) to achieve effective and stimulating communication among all scientists within a discipline and between dis- ciplines in the Commonwealth, (2) to provide a forum for the presentation and publication of scientific work, and which work may also be of specific significance to the Commonwealth, (3) to foster the interaction of science with other sectors in seeking solutions to major social, eco- nomic and environmental problems, (4) to interest the youth of the Commonwealth in science, to encourage them to consider science as a profession and hopefully to practice that profession within the Commonwealth, (5) to provide advisory assistance to the Commonwealth, as well as to local governments, in areas of science and technology. The Academy certainly intends to recognize, encourage, TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3-4) honor and inspire scholarship, intellectual excellence and stimulating research in the pursuit and understanding of nature, and all of its ramifications. It also serves and seeks to encourage interaction of its members with their peers, in stimulating discussion, exchange of information and reporting of scientific information acquired by diligence, hard work, curiosity and dedicated research inquiry. This is accomplished in many ways, and including fellowship in the Academy and the establishment of close interaction with one’s associates dedicated to the same area of inquiry. Hopefully, the Academy can also convey the spirit of ad- venture, the excitement of pioneering discovery, the step- ping off into the unknown, all of which are associated with stimulating research, and professional involvement. Fortunately, in an Academy such as ours, there is also great opportunity to become exposed and acquainted with other areas of interest and to gain a broader perspective and interaction with the world of science and technology. This is also how the Academy functions and can inspire. In this way, the Academy seeks to also encourage inter- action of geologists with psychologists, biologists with phys- icists, botanists with chemists, anthropologists with math- ematicians and combinations and permutations thereof. Generally speaking, only in an Academy of Science, and in the smaller state organization, is such association and interaction possible, and we are all proud of this. For example, have you ever taken the time at an Academy annual meeting, to change your diet, so to speak, and attend some papers in an all together different field? This fall, I decided to do so. Not only did I attend some excellent papers in chemistry and the symposium on coal liquefac- tion, but I decided to also try to attend some others outside of my field. I had a perfectly delightful and scientifically stimulating time listening to several papers on anthropol- ogy, psychology, geology and biology. It seemed to me unfortunate that there was so little time to do this, but what time I did spend, was most stimulating, scientifically speaking, and I truly thirsted for more. I couldn't help but wish the annual meeting would last at least another day, so that I could do more of this. The Academy also provides an opportunity to listen to speakers of national recognition, and by holding our meet- ings at a different university or college each year, it enables each of us to become better acquainted with the many excellent educational and research facilities of the state, and the professionals associated therewith. Industrial site visits are also possible, and enable the academic scientist to become acquainted with the world of industrial science and the industrial scientist, upon which so much economic progress depends. I still receive favorable comments on the meeting held at Ashland in 1982, when for the first time, many academic scientists had an opportunity to learn and observe how their industrial counterparts live. Perhaps we can do it again some time, or find another industrial site for a similar meeting. The Academy has also clearly sensed the importance of recognizing the role of industrial science and technology PRESIDENTIAL ADDRESS in the Commonwealth and, therefore, the importance of encouraging participation by industry and industrial sci- entists. This is manifested in the encouragement I have received in becoming active in the Kentucky Academy, the visit to an industrial site for one of our annual meetings, and the continuing efforts in recent years by our presidents to introduce the industrial affiliate membership concept. Here again, we witness the Academy growing in stature and broadening its base and interests. The Academy and the Junior Academy also stand for ecxellence in education, and here is another role and func- tion of the Academy to encourage and provide leadership in the state in seeking, obtaining and maintaining excel- lence in advanced scientific education and research in our high schools, colleges and universities. There is a tremendous role opportunity for the Junior Academy in promoting science in the state. Today we have 16 senior or junior high schools participating in the Junior Academy program, and another 68 have been active at one time or another. However, this is but a small fraction of 284 senior highs, 31 junior highs, and 118 non-public high schools in the state that could participate, and here is where our increased support of Pat Stewart and his committee could have great impact. Pat, and Herb Leo- pold before him, have had outstanding accomplishments with a minimum of resources and assistance. What an exciting opportunity exists here, if we can intensify their efforts by one means or another. Herb is also drafting a plan and proposal for a Collegiate Academy, and informed me that he hopes to have it ready for presentation to the board sometime later in the spring, hopefully, before the April 29th board meeting. Over the past recent years, the Academy has also begun to direct its attention to the welfare and health of science and science education, especially at the graduate level in Kentucky, both as they relate to education, and as they also relate to enhancing the social, economic and cultural welfare of the state by means of science and technology. This interest led our Academy to greater interaction at the top level of government in such activities as the Kentucky Tomorrow program and later the EPSCoR program. The EPSCoR program not only seeks to stimulate and enhance scientific effort at the level of graduate university research, but to a degree, has sought to tie elements of this basic research program to long-term implications for potential industrial spin off as well. Dr. Charles Kupchella has re- viewed the history of the EPSCoR program in the 1986 spring newsletter. By leadership from the Academy, including Kupchella, Boggess, Rodriguez, and Winstead, to name a few, a bal- anced ad hoc committee of governmental, academic and industrial representatives fashioned a program for the NSF EPSCoR challenge, with an eye to government support of sound and exciting basic academic research, but with at least a long-range, potential implication for industrial en- hancement as well. Dr. Charles Kupchella has so eloquent- ly reviewed the plight of science and technology in Ken- 147 tucky on pages 59-62 of the Transactions, March 1986 (vol. 47), and the need for an effort such as the EPSCoR program to give the scientific community a much needed stimulus. So we see an Academy gradually flexing its strength and injecting leadership into the mainstream of social and tech- nical leadership in the Comonwealth. To a degree, this is a relatively new role for the Academy. In the recent past, there has also been expressed the view that the Academy is made up, overwhelmingly, of biological scientists, although a review of the presidents of the past ten years tends to contradict that concern. Four of the last ten Presidents, myself included, have been from sections in the physical, mathematical and computer sci- ence division. Certainly the biological sciences are to be congratulated for their efforts to enhance and strengthen the growth of the Academy, but with the new constitution’s emphasis on scientific balance, a new dedication to in- crease participation by members of the physical, mathe- matics and computer science division, and social sciences and science education division, should bring about an even stronger Academy. With these comments as background, I'd like to now comment on some of the goals I outlined for this coming year and why I believe they are important and in harmony with the trends and direction in which the Academy ap- pears to be heading. (1) Greater Visibility for the Academy To further assure that our voice may be heard at the level of government and industry as it relates to support of University Research, we need to achieve greater visi- bility. It is still surprising to me to note how little is known about the Academy by even those who might be expected to know. In the past, for those dedicated to enhancing the role of science and technology in the state, there has generally been the belief and conviction that if the level of scientific activity and quality could be lifted, that economic devel- opment and growth would surely follow. It was and is believed that improved educational programs, both at the lower levels of education and at the college, university and graduate school levels, would result in producing a more highly trained and educated work force, making Kentucky more attractive to business and industry, and hopefully, high technology. More recently, although it is still considered high prior- ity to promote both education and economic development, the emphasis appears to be shifting, and to perceive that these objectives can better be achieved by stressing eco- nomic development, which in turn will generate funds by which to enhance education. The problem is not unlike one that is so frequently also observed in industrial America. Corporations seeking to accelerate or assure growth have frequently introduced the so-called “corporate” research laboratory for the avowed purpose of generating new and more innovative products, no longer forthcoming from the “quick fix” approach found 148 at the divisional level. Frequently, however, they have created this function without providing for a commercial development arm by which to exploit these developments. Other firms have created the so-called “commercial de- velopment” department, in a technically based company, without providing for strong technical support. In either situation, the effort is usually doomed, unless both are created simultaneously, and further, that top management provides strong leadership and support over a long period of effort, preferably over several consecutive administra- tions. So too in government, if a state is to grow and prosper in modern America, especially in the face of stiff com- petition from other states and nations, and long head starts of surrouriding states, then strong economic and devel- opment leadership must be harnessed closely with out- standing scientific leadership, and with full support and encouragement of government, if it is to succeed in achiev- ing some industrial impact. Playing “catch up” requires even greater effort than that required for just keeping even. This seems to be the sum and substance of the situation in Kentucky, how to harness outstanding academic per- formance with economic development and government encouragement, so that they are all pulling together, and it is gratifying to note the zeal with which the Academy has sought to support such a troika concept of close inter- action of government, industry and economic develop- ment, and academia over the past 15 years or so. Some- times we have appeared to slide backward, only to pick ourselves up and again move forward. But the steadying gradual progress of the Academy in this endeavor is evi- dent to any who would care to study it, and the EPSCoR program is the first symbolic small victory in this effort. It is for this reason that many of us have concluded that if we are to make the next leap forward and make an even greater contribution, it is required that we achieve greater visibility in the community. To my mind, to achieve greater visibility, and to assert our avowed role, we need a home, one that implies sta- bility, strength and to a certain extent, power. Today the Academy is even hard to find, let alone be recognized. We are like a homeless waif. The records of the President, from one President to the next, can, and are often trans- ferred in a cardboard box. Several years ago, I reviewed information on the 44 academies that form the National Association of Acade- mies of Science. Twenty-seven had a permanent address, most could be reached easily by phone or letter, and 21 had a permanent executive secretary, and/or executive- director. We have discussed the need for such a home for some time. Now is the time to act. To achieve such a goal requires financial support and a good location. By means of an increase in membership (target 1,000 members), and academic and industrial affiliate memberships, and a re- view of our projected income and budget for 1988, it is now possible to foresee that such a goal is attainable, and TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3-4) I and your officers will be giving this goal our attention this year. We also are working hard on public relations. J. G. (Rod) Rodriguez, a former President of the Academy, has gra- ciously and generously volunteered his services as execu- tive secretary of the Academy, and the board has approved my nomination of him to that post. As you know, among many other improvements, the new constitution defines and creates the office of executive secretary, subject to appointment by the president, and approval by the board. Among his other responsibilities as executive secretary, the constitution appoints him Chair of Public Relations, and Rod will, therefore, also be working energetically on this assignment this year to improve our public image and relations. We badly need more and better press coverage, especially for the annual meeting. The Academy has also sought to get the speakers bureau going to assist in bringing recognition to the Academy. However, to date it is stalled out, and needs rejuvenation. Can it be that no one has asked us to speak about the Academy? Again, we need a means to let the public know that we are here, and would like to talk about our efforts and interests. Finally, with regard to this goal, I am pleased to inform you that one small step in our progress toward reaching the goal of a permanent site for the Academy has already been taken. The Academy, with the cooperation of the EPSCoR office, does now have a post office box address (P.O. Box 22313), a zip code (Lexington 40522), and a telephone number (606-257-4902). So you see, small but finite progress is being made. (2) Broader Participation in the Transactions In my discussions with both academic and industrial scientists, there has been skepticism expressed as it relates to the small number and quality of papers published in the Transactions, but even more importantly, the narrow- ness of coverage. This year we will seek your help to encourage greater participation by the physical science, mathematics and computer sciences division and the social science and science education division, not only at the annual meeting where it is already very good, but more importantly, in publishing in the Transactions. We need much better participation in order to achieve a balanced publication. Your President-elect, Mr. Richard Hannan, in his assignment as program chair, plans to encourage greater emphasis on publications by the secretary and chair of each section so as to help us encourage publication in the Transactions. Branley Branson and members of the editorial committee are also committed to seeking and encouraging broader publication participation in the Transactions. (3) Greater Interaction with Industrial and Govern- mental Scientists For the many reasons already discussed and for many other reasons which could be mentioned, I have also set as a goal to at least double the number of industrial and governmental scientist members, and to increase the num- PRESIDENTIAL ADDRESS ber of industrial affiliates. There is a great disparity in the number of industrial and governmental scientists relative to academic scientist members, and this problem reflects either a disinterest or reluctance on the part of industrial scientists to become active, or more appropriately, and significantly, it bespeaks of the low level of industrial re- search in the Commonwealth, relative to other more tech- nically successful states. Here we have again a reminder of our problem. Except for a few islands of excellence, we do not have a strong, high technology industrial sector, compared with surrounding states. As we seek to enlist industrial affiliates in this effort, perhaps this too will help enhance our upward struggle to enhance the welfare and economy of the state. (4) Introducing the New Constitution A final objective, as mentioned in my short acceptance speech last November, had to do with my concerns for implementing the new constitution. But this concern ap- pears unfounded. The new Executive Committee and Gov- erning Board met for our first business meeting of the year on January 23, and appears to be off to a great start. Everyone, and including committee chairs, have dug in with great enthusiasm, and give promise of leading the Academy to another great year. Having said all of that, I would like to return to a review of progress and accomplishments over the past year and acknowledgment of all of those who were so intimately involved. Our outgoing President, Larry Giesmann, is to be highly complimented for the many accomplishments of last year. His theme for the year, “Service to and Through the Acad- emy , was most successful. His goal to achieve approval for a revised constitution, which constitutional revision was undertaken by an ad hoc committee chaired by former Academy President, J. G. (Rod) Rodriguez, and including two other former Presi- dents, Ted George and Gary Boggess as committee mem- bers, was most successful, and is now in place. It is a significant improvement over the old constitution and pro- vides the Academy with a document which the officers, governing board, and members can understand and follow. It also provides for a more understandable election pro- cedure, and better distribution of scientific disciplines on the governing board. This achievement of a new consti- tution was a a most significant accomplishment of the ad hoe committee and of the many past presidents, as well as those who proposed and supported this effort. A second most useful achievement of Larry’s adminis- tration was the initiation and development of a member- ship database which provides the Academy with much needed information in a host of areas, including a mem- ber’s areas of expertise, educational background and in- terest, interest in committee activities and much other valuable information for ready retrieval. This system is now up and operating, most of it due to personal effort on Larry’s part. His wife confided to me the many nights when she looked for him at three in the morning, she 149 found him intensely involved in incorporating this infor- mation into his computer. This database promises to be- come one of our most valuable assets. Other activities and accomplishments of last year in- cluded a study to streamline accounting procedures by Paul Freytag, Alan Reed and Manuel Schwartz, and the formation of a committee to improve long-range planning for our annual meetings lead by Debra Pearce and assisted by Frank Howard, Gerrit Kloek and Joe Winstead. The handbook prepared by this committee should be most valu- able for planning and hosting our annual meeting. Membership again increased last year due to the efforts of Doug Dahlman and his committee. As of January 15 of this year, there were 573 members paid through 1987- 88, 50 life members and 24 emeritus members, for a total of 647. There were an additional 179 members in arzears for two years or more, but very likely many of these will catch up on their dues this year. If half return, this could bring us to 736 by mid year. I have set as a challenge, membership goal of 1,000 for 1989, our 75th year. The number of university affiliates remained steady at an impressive level of eight universities and fourteen col- leges. Industrial affiliates have now risen from three to five and are targeted for additional increases. They represent a great long-range potential for increasing funding and support. Income from both of these sources continues to grow and represents a key base for financial soundness of the Academy. Under the guidance of Branley Branson, Editor, and the Editorial Committee, our printing problems were fi- nally resolved, and the Transactions are now also back on schedule and look very nice. Overall, as noted in the treasurer’s report presented at the Academy business meeting, the Academy has begun to achieve a sound financial position, and can begin to look forward to using this asset to further accelerate the activities and accomplish the goals set forth in our con- stitution. Because of this, the next few years show promise for exciting and significant contributions by the Academy to the scientific, educational and industrial climate in and for the Commonwealth. Perhaps this letter could go on describing other progress during the year, and because so many people should and could be recognized for their many contributions. But because of space limitations, I'd like to express my thanks to all of you, both the named and the unnamed, the thanks and gratitude of your past President, Larry Giesmann, the entire executive committee and the governing board for all you have done. In closing, I would also like to express my thanks to all of the individuals who have agreed to chair and/or serve in the coming year on the many committees and ad hoc committees defined and described by the new constitution. Your willingness to serve was most gratifying to me, and I am most grateful for it. I trust that in the days ahead, with your help and with the help, guidance and wisdom of the governing board and officers of the Academy, that 150 we will not only keep this momentum going, but accelerate to even greater accomplishments. There is much to be done in the state and I am excited as to the ability of your Academy to make things happen. My theme for the coming year is “Enhancing Academy of Science Recognition in the Commonwealth.” I want you to know that I am very grateful for the honor bestowed upon me, and proud to be serving as your President. With your help and support, I look forward to another exciting TRANS. KENTUCKY ACADEMY OF SCIENCE 49(3-4) and rewarding year, with a continuing escalation of ac- complishments. Please plan to attend the annual meeting, November 4 and 5, at Eastern Kentucky University, Rich- mond, Kentucky, and please be thinking and planning for that big 75th annual meeting at the University of Kentucky in 1989. Have a good spring and summer and see you at Eastern in the fall! Trans. Ky. Acad.

Also, as the official publication of the Academy, news and announcements of interest to the membership will be included as received. Manuscripts may be submitted at any time to the Editor. Each manuscript will be reviewed by ‘one or more persons prior to its acceptance for publication, and once accepted, an attempt will be made to publish papers in the order of acceptance. Manuscripts should be typed double spaced throughout on good quality white paper 8% x 11 inches. NOTE: For format of feature articles and notes see Volume 43(3-4) 1982. The original and one copy should be sent to the Editor and the author should retain a copy for use in correcting proof. Metric and Celsius units shall be used for all measurements. The basic pattern of presentation will be consistent for all manuscripts. The Style Manual of the Council of Biological Editors (CBE Style Manual), the Handbook for Authors of the American Institute of Physics, Webster’s Third New International Dictionary, and a Manual of Style (Chicago University Press) are most useful guides in matters of style, form, and spelling. Only those words intended to be italicized in the final publication should be underlined. All authors must be members of the Academy. The sequence of material in feature-length manuscripts should be: title page, abstract, body of the manuscript, acknowledgments, literature cited, tables with table headings, and figure legends and figures. 1. The title page should include the title of the paper, the authors’ names and addresses, and any footnote material concerning credits, changes of address, and so forth. 2. The abstract should be concise and descriptive of the information contained in the paper. It should be complete in itself without reference to the paper. 3. The body of the manuscript should include the following sections: Introduction, Materials and Methods, Results, Discussion, Summary, Acknowledgments, and Literature Cited. All tables and figures, as well as all literature cited, must be referred to in the text. 4. All references in the Literature Cited must be typewritten, double spaced, and should provide complete information on the material referred to. See Volume 43(3—4) 1982 for style. 5. For style of abstract preparation for papers presented at annual meetings, see Volume 43(3- 4) 1982. 6. Each table, together with its heading, must be double spaced, numbered in Arabic numerals, and set on a separate page. The heading of the table should be informative of its contents. Each figure should be reproduced as a glossy print either 5 x 7 or 8 x 10 inches. Line drawings in India ink on white paper are acceptable, but should be no larger than 8% x 11 inches. Pho- tographs should have good contrast so they can be reproduced satisfactorily. All figures should be numbered in Arabic numerals and should be accompanied by an appropriate legend. It is strongly suggested that all contributors follow the quidelines of Allen’s (1977) “‘Steps Toward Better Scientific Illustrations” published by the Allen Press, Inc., Lawrence, Kansas 66044. The author is responsible for correcting galley proofs. He is also responsible for checking all literature cited to make certain that each article or book is cited correctly. Extensive alterations on the galley proofs are expensive and costs will be borne by the author. Reprints are to be ordered when the galley proofs are returned by the Editor.
