HAVEN Department of Geography, University of Kentucky, Lexington, Kentucky 40506 ABSTRACT One of the major development trends during recent times has been the economic and popu- lation growth of nonmetropolitan America. After years of decline, nonmetropolitan areas are experiencing unprecedented growth rates while major metropolitan areas are slowing down or losing population. The magnitude of this reversal of former trends has led several authors to speculate on the reasons and meaning of this turnaround for the changing urban system. A debate has ensued whether recent nonmetropolitan growth is merely the residual spread effects of metropolitan decentralization or if this growth represents a clean break with past urbanization processes. This paper examines the nature of these forces within the intermetropolitan periphery of western Kentucky, by comparing changes in the external and internal commuting fields of this region between 1960 and 1970. INTRODUCTION Although the population growth rate of nonmetropolitan areas during the 1970s has been impressive, the economic growth of these regions has been sub- stantial since the early 1960s and can be explained within a regional development framework synthesizing elements of growth-center theory and the product- cycle model. Growth-center theory ex- plains the spatial distribution of eco- nomic activity in terms of relationships between a growth center and its hinter- land. Basic to the growth of a region is the capacity for attracting industries that produce goods for export to other regions. As foci for investment, growth centers first manifest polarization attracting the fac- tors of production from peripheral areas and often accentuating spatial disparities in the economic development of a region (1). During the polarization stage, ex- tended commuting is one mechanism by which a center extracts the labor pool it needs from the periphery. Holmes (2) suggested that extended commuting may in fact be a prelude to outmigration from rural areas to metropolitan areas and should continue to expand into nonmetro areas filling in the intermetropolitan periphery (3). However, because commuting is a spatial income redistribution mecha- nism, it has been proposed by Hansen (4) as a possible solution to the employment problems of economically depressed, ru- ral areas. Thus, extended commuting also has the potential to transmit growth im- pulses back to the periphery through in- come multipliers. Additionally, growth impulses are transmitted to nonmetro areas through the diffusion of mature industries from met- ropolitan centers. Between 1962 and 1978, 56 per cent of the total increase in 2 TRANS.

U.S. manufacturing jobs were added to nonmetropolitan areas (5). The most fre- quent explanation for this shift has been the “‘filterdown” process or product-cycle model (6, 7). Large urban areas, with their external economies of scale, incubate new industry and enjoy the rapid growth as- sociated with the early stages of an in- dustry’s life cycle. However, as the in- dustry matures and the production process becomes standardized, increas- ing competition and high-wage rates in the metropolitan market may force the firm to relocate production in smaller set- tlements where cheaper labor can per- form the simplified production process. In time, as industries and retail activity relocate in the periphery, the need for ex- tended commuting is reduced. In fact, ex- tended commuting may accentuate the redistribution of economic activities to the hinterland by training the labor force in the necessary industrial skills. Thus, small centers within the periphery will emerge as foci for employment opportunities, manifesting polarization themselves, al- though at a lesser intensity than their larger metropolitan counterparts. The ex- pansion of large urban commuting fields should slow down as internal commut- ing, commuting within the intermetro- politan periphery, becomes more impor- tant. The study area—the intermetropolitan periphery of western Kentucky. Any shifts occurring in the regional dis- tribution of economic activity should be reflected in the extent and intensity of lo- cal commuting fields over time. A com- parison of extended and intemal com- muting pattems should aid in ascertaining whether the residents of the intermetro- politan periphery are bound to metropol- itan areas for employment opportunities or whether smaller intermetropolitan centers are emerging as foci for employ- ment. The area selected for the investigation of these trends comprises the 57 non- metropolitan counties in Kentucky that lie west of the Appalachian Regional Com- mission's delineation of the Appalachian portion of Kentucky (Fig. 1). The devel- opment of the nonmetropolitan counties ot these two regions has differed signifi- cantly. Eastern Kentucky has a long his- tory of being a stagnant, economically de- pressed region tied to the boom and bust cycle of the coal industry, while western Kentucky has a more diversified econo- my with stronger ties to agriculture and industry. Although western Kentucky had its highest population growth rate of recent times during the 1970s (12.6%), the major turnaround for this region occurred dur- ing the 1960s. After experiencing a pop- ulation loss during the 1950s (—2.5%), the COMMUTING PATTERN CHANGES IN KENTUCKY— ZERO PERCENT EXTENDED COMMUTING FIELDS, I960-70 Cromley and Haven 3 Fic. 2 population of western Kentucky grew at a rate of 9.3% during the 1960s (8). This time period of turmaround is more rele- vant to the analysis of commuting changes within the region if population growth is indeed related to the provision of em- ployment opportunities. METHODS AND MATERIALS Six Standard Metropolitan Statistical Areas (SMSAs) that lie adjacent to the study area—Cincinnati, Ohio; Louisville, Kentucky; Lexington, Kentucky; Evans- ville, Indiana; Owensboro, Kentucky; and Clarksville, Tennessee/Hopkinsville, Kentucky—provide the basis for exam- ining extended commuting patterns for the region (Fig. 1). An earlier analysis of commuting destinations among the non- metropolitan counties (9) identified 9 counties (with 9 associated centers)— Warren (Bowling Green), Hardin (Eliza- bethtown), Taylor (Campbellsville), Bar- ren (Glasgow), Boyle (Danville), Frank- lin (Frankfort), Hancock (Hawesville), Hopkins (Madisonville), and McCracken (Paducah)—as major intermetropolitan destinations (Fig. 1). The data were compiled from the Bu- reau of the Census 1960 and 1970 samples of commuting behavior (a 25% sample in 1960 and a 15% sample in 1970). The 260 census-county divisions (CCDs) in the 57 county region were used as the areal units Zero per cent extended commuting fields, 1960-70. for commuter origins. The 9 counties mentioned above were used as the des- tinations for all internal commuting; the central counties of the 6 contiguous SMSAs were used as the destination for the measure of extended commuting, ex- cept for the Clarksville, Tennessee/Hop- kinsville, Kentucky SMSA. Because Christian ‘County had a higher level of nonmetropolitan commuters from west- erm Kentucky than did the central county of the SMSA, it was chosen as the desti- nation for the measurement of extended commuting for this SMSA. RESULTS Both cartographic and regression anal- ysis were performed to analyze any rel- evant changes in the commuting fields of SMSA and nonmetropolitan destinations between 1960 and 1970. Results suggest that the residents of western Kentucky are becoming less bound to metropolitan areas for employment opportunities. In fact, where commuting option zones exist residents may have several alternative workplace destinations to choose from within the intermetropolitan periphery along with the possibility of commuting to a metropolitan center. DISCUSSION A zero per cent isoline map enclosing all CCDs with any commuters to an SMSA 4 TRANS. KENTUCKY ACADEMY OF SCIENCE 44(1-2) Fic. 3. Zero per cent internal commuting fields, 1960-70. was used to analyze the expansion of ex- tended commuting between 1960 and 1970 (Fig. 2). Although this measure has been criticized by Taaffe et al. (10) and Hansen (4) as a poor indicator of urban influence, it does denote the limit of ex- tended commuting within the periphery. While the change in the expanse of ex- tended commuting was minimal between 1960 and 1970, the overall number of CCDs within the zero per cent isoline declined from 163 in 1960 to 153 in 1970 (Table 1).

Each individ- ual field also expanded except Camp- bellsville which stayed the same (Camp- bellsville expanded more in the intermetropolitan periphery of Kentucky outside the study area). Hawesville clear- ly displayed the greatest overall expan- sion. To analyze the intensification of com- muting during the 1960s, commuting pro- files were constructed displaying the av- erage commuting percentages of a given destination by distance bands. These percentages are based on the average of actual commuters for only those nonme- tro CCDs representative of some degree of commuting. CCDs with no commuters to the central county were excluded. A regional profile of extended com- muting by distance bands displays a gradual distance decay, and an overall up- ward shift of commuting percentages from 1960 to 1970 is evident (Fig. 4). This in- tensification is occurring not only at dis- tances close to the SMSAs but also at dis- tances far from these destinations. In fact, the greatest percentage change in the in- tensification of extended commuting is at distances of 55-75 miles from the central SMSA county. The commuting profiles for individual SMSAs also display a greater intensity of commuting in 1970 as com- pared with 1960 with the exception of Owensboro. The regional profile for internal com- muting by distance bands displays an in- tensification of commuting similar to the CA) 7 % COMMUTING 3 T 1 =!)

Along with a gradual distance decay, there is also an overall upward shift of commuting percentages from 1960 to 1970. This intensification of internal commuting represents a 67.0 per cent in- crease in the overall percentage of inter- nal commuters. As opposed to the region- al profile of extended commuting, the intensification of internal commuting is occurring near the intermetropolitan cen- ters especially at distances 15-25 miles away. Likewise, the commuting profiles for the individual intermetropolitan centers display some degree of commuting inten- sification with Hawesville experiencing the greatest change in commuting inten- sification. Negative externalities associ- ated with the numerous primary metal and wood pulp industries and a housing shortage in Hawesville may be facilitat- ing the desire to live farther away from the job opportunities located there. Finally, a series of forward stepwise regression analyses are employed to identify the significant factors that best explain the spatial patterns of nonmetro- politan commuting in western Kentucky between 1960 and 1970. Factors describ- ing the accessibility of an origin CCD to respective destinations, factors describ- ing the strength of smaller competing centers and factors describing the site characteristics of the origin CCD were used to measure the strength of both ex- tended and internal commuting patterns. For this study a positive linear relation- ship is expected between the number of commuters to a given destination with: 6 TRANS.

A negative linear relationship is expected between the number of commuters to a given destination with: (1) the Euclidean distance from the center of the origin CCD to the central city of the destination county; (2) the population of the compet- ing center; (3) the total number of the ci- vilian labor force age 14 and over em- ployed in the nearest competing center; and (4) the percentage of the civilian la- bor force age 14 and over unemployed in the destination county. Examining the correlates of extended commuting through a regional profile of the study area for 1960, the Euclidean distance from the origin to the destina- tion, the population of the destination, the percentage unemployed in the destina- tion, and the total number employed in the origin are significant variables (Table 3). These 4 variables accounted for 35.2 per cent of the variation in the number of extended commuters for the study area as a whole. The population of the destina- tion is the most important variable. Des- tinations with larger populations and pos- sibly a more diverse economic base, provide potential commuters with ex- panded employment opportunities. Fur- thermore, commuters may be taking jobs away from the local labor force, as the linear relationship between the depen- dent variable and the percentage unem- ployed in the destination is positive rath- er than negative. In 1970, the distance variable, the total number employed in the origin, and the total number employed in the nearest competing center entered the regression equation significantly, accounting for 45.4 per cent of the explained variance. Al- though the distance variable exerts the most effect on the number of extended commuters within the study area for 1970, it must be noted that the role of compet- ing centers within the intermetropolitan periphery was more significant in 1970 than in 1960. Next, the correlates of internal com- muting were determined by a regional analysis of the study area for 1960. Dur- ing this time period, the population of the origin, the distance to the destination, the population of the destination, and the total number employed in the origin COMMUTING PATTERN CHANGES IN KENTUCKY—Cromley and Haven rth together accounted for 74.4 per cent of the explained variance (Table 3). The population of the origin is the most im- portant. In 1970, the population of the origin, the distance to the destination, and the total number employed in the origin ac- count for 61.7 per cent of the explained variance. Not only is the population of the origin again the most important vari- able, but the increased magnitude of its beta coefficient displays the increased strength of this particular variable. This is an indication that the larger the origin population, the larger the potential num- ber of commuters. For both years, the relationship be- tween the number of internal commuters and the total number employed in the or- igin is unexpectedly negative. This may be an indication that employment oppor- tunities within the intermetropolitan pe- riphery are increasing. As employment increases in many nonmetropolitan CCDs, the need to commute outside one’s own community is diminished. Clearly, this intensification of employment oppor- tunities and the growing population of many nonmetropolitan areas may be sig- nificant factors in the commuting process. SUMMARY Similar to studies done by Taaffe et al. (10) and Fisher and Mitchelson (11, 12), there is little evidence that the interme- tropolitan periphery of western Kentucky counties is shrinking. While there is evi- dence of a diminishing intermetropolitan periphery as extended and internal com- muting fields show some degree of ex- pansion, the greatest change is in an in- tensification of commuting. Similarly, a regression analysis of extended commut- ing suggests that competing centers in nonmetropolitan counties are diverting a significant number of commuters away from metropolitan destinations by pro- viding more employment opportunities closer to home. The increased intensity of commuting to nonmetropolitan centers suggests that many of these smaller centers are indeed emerging as foci for employment. While the number of commuters to SMSAs in- creased 42.2 per cent over the ten-year period, the number of internal com- muters to intermetropolitan centers in- creased 67.0 per cent. The growing im- portance of these intermetropolitan centers may be due in part to growth im- pulses being transmitted back to periph- eral areas from metropolitan areas them- selves. Filter-down effects may have reached into the intermetropolitan pe- riphery as some of these smaller centers such as Bowling Green and Elizabeth- town begin to manifest polarization char- acteristics themselves.

Department of Biological Sciences, Eastern Kentucky University, Richmond, Kentucky 40475 ABSTRACT One genus and 3 species of sphaeriid clams and 6 families, 12 genera and 23 species of aquatic snails are reported from the Tradewater, Tennessee and Green river systems and from some small tributaries of the Ohio River in Kentucky. INTRODUCTION During our work on the rare and en- dangered species of Kentucky (1), it be- came obvious than many sections of Ken- tucky were poorly represented in the literature on aquatic snails and fingernail clams. Because of this, we recently gen- erated a series of papers (2, 3, 4, 5) de- signed to alleviate the lack of information in those 2 groups of conspicuous aquatic organisms. This contribution, a contin- uation of that series, treats records gleaned from drainages west of the Ken- tucky River basin. COLLECTING SITES In the annotated list of species, col- lecting sites are indicated by the num- bers listed below; the figures in paren- theses indicate the number of specimens collected at each site. 1.

ANNOTATED LIST Voucher specimens of all species re- ported herein are in the Eastern Ken- tucky University Museum. SPHAERIIDAE Sphaerium fabale Prime Collecting sites: 9 (1). This habitat was muddy gravel and sand at the edge of a slow riffle. Sphaerium similis (Say) Collecting sites: 9 (2). This heavy shelled species is adapted for life in backwaters and lakes with sandy, vegetated bottoms. It is mostly as- sociated with streams in englaciated parts of America (6). However, the Green Riv- er was a refugium for northern species during Pleistocene times (7) so it is not surprising to find residual populations of species such as this one. Sphaerium striatinum (Lamarck) Collecting sites: 11 (5), 12 (2). This is the most common stream sphae- riid in Kentucky. PLEUROCERIDAE Our collections contained representa- tives of 3 genera and 10 species of this taxonomically confusing family. Lithasia verrucosa (Rafinesque) Collecting sites: 27 (4). This species is correctly considered as Endangered in Kentucky (1) and is being considered for federal listing (8). Lithasia obovata (Say) Collecting sites: 5 (1), 6 (9), 12 (1), 18 (2), 23 (14), 24 (8). Lithasia obovata is listed as of Special Concern in Kentucky (1). However, in view of the large populations of the species in the Green, Rough, and Salt rivers, it probably should be delisted. Pleurocera acuta Rafinesque Collecting sites: 1 (2), 6 (1), 23 (5), 28 (1) An uncommon species in the Kentucky River drainage (3, 5) and listed as of Spe- cial Concern in Kentucky (1), P. acuta ap- pears to be thriving in the Green and Salt rivers. 10 TRANS. KENTUCKY ACADEMY OF SCIENCE 44(1-2) Pleurocera canaliculatum (Say) Collecting sites: 6 (6), 23 (5), 27 (2). This species is likewise of Special Concern (1), particularly in the Kentucky River drainage. Pleurocera alveare (Conrad) Collecting sites: 3 (2). There is a thriving community of this species in Fallen Timbers Creek. Goniobasis semicarinata (Say) Collecting sites: 21 (92), 24 (21), 25 (30), 29 (5). This is the most common pleurocerid throughout the Kentucky River drainage (4) and, as indicated above, produces at least some populations in Salt River. It has been recently reported from the Lit- tle South Fork of the Cumberland River (5). The population discovered in Bear- grass Creek in Jefferson County (Station 29), a tributary of the Ohio River, is an interesting one in relation to 2 sites from the Green River, Kentucky, and the Big Blue River, Indiana (9, 10), emphasizing the importance of the Ohio River and smaller tributaries that possibly func- tioned in tributary hopping during re-ex- pansion migrations in post-glacial times. Goniobasis costifera (Haldeman) Collecting sites: 5 (1), 11 (19), 14 (9), 18 (11). To our knowledge, this species has heretofore not been reported from Ten- nessee. Goniobasis laqueata (Say). Collecting sites: 2 (3), 3 (3), 9 (26), 12 (57). This is the characteristic Goniobasis of the Middle and Lower Green River and its tributaries (9). It was the dominant species present in the Rough River (sta- tions 9 and 12). Goniobasis curreyana (Lea) Collecting sites: 10 (1), 14 (4), 19 (2). Bickel (11) also reported specimens from Otter Creek (near our Station 19) and suggested that the species would proba- bly be found in other parts of the Green River. Our collections corroborate his prognostications. VIVIPARIDAE The principal references to this family were Clench (12), Clench and Fuller (13), and Clench and Tumer (14). Viviparus georgianus Lea Collecting sites: 8 (8). These are some of the few records for this large operculate from Kentucky. HYDROBIIDAE A very poorly understood family in Kentucky. Our collections contained specimens of one amphibious species. Pomatiopsis cincinnatiensis (Lea) Collecting sites: 30 (7). Our specimens closely resemble those of van der Schalie and Dundee (15). The same authors (16) reported this species from a site in the Upper Cumberland Riv- er in Kentucky, and there are few addi- tional known sites in the state. LYMNAEIDAE Our generic and species concept in this family follows Hubendick (17, 18). Three species are reported. Lymnaea humilis Say Collecting sites: 7 (2). Lymnaea humilis is a highly variable species that is found in both standing and slowly running water. Lymnaea palustris (Muller) Collecting sites: 31 (1). There are very few records for this species in Kentucky, and the ecology is poorly understood. It is often associated with bodies of water frequented by mi- gratory birds. Lymnaea (Pseudosuccinea) columella (Say) Collecting sites: 4 (2), 7 (2), 16 (2). Found mostly in stagnate ponds and backwaters, this snail is often heavily lad- en with fluke larvae. PHYSIDAE One of the most confusing and variable groups of aquatic snails in North Ameri- ca, the Physidae is represented in Ken- tucky by the genus Physa. Until the fam- ily is thoroughly studied and revised, any SNAILS AND CLAMS FROM KENTUCKY—Branson and Batch 1l specific identification is tentative, as are the 4 species reported here, based entire- ly upon shell features. Physa integra Haldeman Collecting sites: 13 (4), 15 (3), 22 23 (1), 32 (7), 33 (35). Typically with long spires and inflated body whorls, Physa integra is often found in flowing waters, although it also occu- pies backwaters and lentic waters. Physa virgata Gould Collecting sites: 31 (18). The shell is usually slender with a long spire and a short, narrow aperture. The habitat is usually well-vegetated stand- ing waters over mud bottoms. (8), Physa heterostropha (Say) Collecting sites: 20 (1). Physa heterostropha is a rather squat species with an inflated body whorl, a short spire, and a capacious, elongated aperture. Physa gyrina Say Collecting sites: 4 (5), 7 (1), 15 (2), 31 (1). ANCYLOPLANORBIDAE We follow Hubendick (17) in combin- ing the Planorbidae and Ancylidae. Five genera and 6 species are reported here. Ferrissia rivularis (Say) Collecting sites: 24 (1), 25 (1). Because of the clandestine habitat on stones, pelecypod valves, snail shells, and other objects in lotic situations, this and other members of the Tribe Physastrini are often overlooked in general collect- ing. Hence, published records for the Kentucky erana are few. Laevapex fuscus (C. B. Adams) Collecting sites: 5 (2), 16 (5). Mostly a lentic species, this snail is often found in backwaters on submerged limbs and rocks. Gyraulus parvus (Say) Collecting sites: 26 (2). The scanty published Kentucky rec- ords for this and other minute Planorbi- nae reflect inadequate collecting rather than scarcity. Planorbula (Menetus) sampsoni (An- cey) Collecting sites: 17 (3). This is one of three reported sites for this species in Kentucky. We follow Hu- bendick (17) in utilizing Planorbula rath- er than Menetus. Helisoma trivolvis (Say) Collecting sites: 4 (25), 11 (1), 31 (17). Found in both lentic and lotic waters, H. tribolvis occurs statewide, as does the next species. Helisoma anceps (Menke) Collecting sites: 12 (2).

Freshwater Naiads (Mussels) (Pelecypoda: Bivalvia) of Slate Creek, A Tributary of the Licking River, Kentucky RALPH W. TAYLOR AND BEVERLY SPURLOCK Department of Biological Sciences, Marshall University, Huntington, West Virginia 25701 ABSTRACT During the summer and fall of 1981, collections of freshwater naiads (mussels) were made from 6 sites along Slate Creek, a tributary of the Licking River. Nineteen species of naiads were found. Two species, Fusconaia maculata and Epioblasma triquetra, are currently considered endangered, threatened, or rare in Kentucky. Fusconaia maculata is a rather rare shell in Slate Creek, but Epioblasma triquetra was extremely abundant throughout the stream. All other species reported are commonly found throughout Kentucky. Slate Creek, a tributary of the South Fork of Licking River, is a rather short (approximate length 40 km) eastcentral Kentucky stream, but one which has a rich and diverse naiad fauna. The stream orig- inates in the rolling hill region of Mont- gomery County, Kentucky approximately 12.8 km SE of Mount Sterling and mean- ders through Bath County to its conflu- ence with the South Fork of the Licking River ca. 9.6 km E of Owingsville. Slate Creek rarely exceeds 2 m in depth and 10 m in width. The substrate is sand and cobble with an occasional stretch of ex- posed bedrock. The water quality is quite good as no industries or urban centers are located within the drainage. During the summer and fall of 1981, collections of freshwater naiads (mussels) were made at irregular intervals from 6 stream sites, mostly by picking in shallow waters (Table 1). Other records were de- rived from bank shell debris. No live specimens were taken when fresh dead material of equivalent species could be found and used as voucher specimens. Reference specimens are housed in the Marshall University Malacological Col- PELECYPODS IN KENTUCKY—Taylor and Spurlock 13 TABLE 1.—FRESHWATER MUSSELS FOUND AT EACH SITE Species Anodonta grandis (Say 1829) Anodontoides ferussacianus (Lea 1834) Strophitus u. undulatus (Say 1817) Alasmidonta viridis (Rafinesque 1820) = calceolus (Lea 1830) Lasmigona costata (Rafinesque 1820) Tritogonia verrucosa (Rafinesque 1820) Quadrula quadrula (Rafinesque 1820) Quadrula pustulosa (Lea 1831) Amblema plicata (Say 1817) Fusconaia maculata (Rafinesque 1820) = swbrotunda (Lea 1831) Fusconaia flava (Rafinesque 1820) Elliptio dilatata (Rafinesque 1820) Ptychobranchus fasciolaris (Rafinesque 1820) Actinonaias carinata (Barnes 1823) Potamilus alatus (Say 1817) Villosa iris (Lea 1829) Lampsilis radiata luteola (Lamarck 1819) = siliquoidea (Barnes 1823) Lampsilis ventricosa (Bames 1823) Epioblasma triquetra (Rafinesque 1820) Corbicula fluminea (Miller) was found at all stations. 1 2 3 4 5 6 xX X xX Xx Xx Xx XxX x xX X Xx xX X xX xX xX Xx X Xx X xX X X X Xx XxX X Xx xX X Xx xX Xx xX Xx Xx X xX xX xX X Xx X X xX X xX Xx Xx xX Xx DA X X xX xX X X xX X Xx xX X xX XxX X X xX Xx Xx xX xX xX Xx xX lections and the Ohio State University Museum of Zoology.

At all sites the number of mussels present was phenom- enal considering the small size of the stream. Fusconaia maculata and Epioblasma triquetra are currently on the list of (En- dangered, Threatened, and Rare Animals and Plants of Kentucky) (2). Fusconaia maculata is a rather rare shell in Slate Creek, but E. triquetra was found to be extremely abundant throughout the stream. All other species reported are commonly found throughout Kentucky. The exotic Asian clam (Corbicula flumi- nea) was found at all stations in large numbers. LITERATURE CITED 1. Stansbery, D.H. 1981. Naiad Mollusks of the Ohio River Drainage System. Ohio State Univ.

This represents 16 new county records. Several reports extend the ranges of species into the eastern third of the state. INTRODUCTION Cranfill’s (1) monograph summarized much of the information on the pterido- phytes of Kentucky. However, distribu- tional data is lacking for many of the east- ernmost counties. This study assesses the status and ecological relationships of pteridophytes in Pike County, Kentucky. Field work for this project was conducted from November 1980 to November 1981, throughout Pike County and adjacent areas. Nomenclature and taxonomic treat- ment follow Cranfill (1). Voucher speci- mens were placed in the Pikeville Col- lege herbarium and duplicate specimens in the University of Kentucky herbarium. Pike County, largest and eastemmost county in Kentucky, lies within the Cum- berland Mountain-Cumberland Plateau physiographic region (2) and within the Mixed Mesophytic Forest floristic prov- ince as delineated by Braun (3). Hills are steep throughout the county with little bottomland between. Elevations range from 183 m along the Big Sandy River to over 854 m on Pine Mountain and the Dorton Flatwoods. Most of the county has a local relief of 213-366 m. Forests in the county are mainly successional, com- posed of a mesophytic buckeye-bass- wood-tulip-maple association on north and lower south-facing slopes, beech- mixed oak on south-facing slopes, and oak-hickory on upper slopes and ridges. Oak-pine is found on the more sandy ridges and hemlock-rhododendron oc- curs in the cooler ravines, becoming most common on Pine Mountain. Forty-one species are reported from Pike County, 16 of which are new county 14 records, and 2, Lygodiwm palmatum and Cystopteris bulbifera, have been report- ed previously in the county but were not found in this study (Table 1). DISCUSSION LYCOPODIACEAE Lycopodium digitatum is common in a variety of habitats, including cutover hill- sides where successional processes have not produced a closed canopy. It also in- vades partly shaded roadsides and forest edges in addition to being common in more mature woods. Lycopodium obscu- rum has been found only in the vicinity of the highest peaks of the county. OPHIOGLOSSACEAE Ophioglossum pycnostichum is appar- ently more common in eastern Kentucky than present records indicate. Three scat- tered colonies were located, each occur- ring on level, but not flooded areas, such as wooded benches on hillsides. In one locality a colony was associated with black walnut-ash-buckeye on a mid-slope bench of a south-facing slope. In a second lo- cality, Ophioglossum pycnostichum oc- cupied a small bench on a west-facing slope under a stand of beech, and in a third site it was on a shaded lower slope under sycamore-hemlock. The common factors in each case were level, non-in- nundated habitats. Botrychium dissectum is one of the most conspicuous fall and winter com- ponents of woodlands and successional edges. This highly variable species is represented by the common var. obli- quum with occassional var. dissectum in- termixed.

Several populations of avery robust, lush Botrychium have been located on shaded, mesophytic lower slopes of ravines. It appears that this is the same plant referred to as B. johnsonii by Johnson (4), and collected by him in nearby Johnson County, Kentucky. We have located a site where B. johnsonii oc- curs mixed with typical B. dissectum and another site where B. johnsonii occurs in pure colonies. The specific status of this plant is currently under investigation by Dr. Warren H. Wagner and the senior au- thor. OSMUNDACEAE The genus Osmunda is not common in Pike County although the county lies well within the range of all 3 species of the genus. Only on Pine Mountain are large populations encountered, and this was the only locality in which O. regalis and O. claytoniana were located in this study. Osmunda regalis requires constantly moist wetland conditions and its sparse distribution in the county reflects the paucity of undisturbed wetlands. ASPLENIACEAE The genus Asplenium is well repre- sented in Pike County with 9 species. In the Appalachian Asplenium complex (5) the 3 parent species are found as well as 4 species of hybrid origin. Asplenium rhizophyllum is common on shaded, moss-covered sandstone boulders and outcrops, being distributed from creek bottoms to the shaded side of ridge out- crops. It should be emphasized that A. rhizophyllum is not a limestone species. 16 TRANS. KENTUCKY ACADEMY OF SCIENCE 44(1-2) Asplenium platyneuron, abundant on south-facing slopes, successional wood- lands, and rock outcrops, is infrequent on north-facing mesophytic slopes. At the base of a sandstone outcrop on the Pike- ville College Farm, Johns’ Creek, both A. rhizophyllum and A. platyneuron are found intermixed in a small colony. Ap- proximately 1 m from this site, in a shad- ed crevice at the base of the outcrop, grows | tuft of A. x ebenoides. The third parent species in the com- plex, A. montanum, is mainly found on cool, moist, sandstone outcrops and is thus more common on Pine Mountain than in other parts of the county. Aspleniwm bradleyi has been found in 3 localities and A. x trudellii in 1 locality near Caney Creek and 1 locality on the Virginia side of the Breaks Interstate Park. Due to the richness of the genus in the county, other members of the complex can be expected to be found in the future. In the genus Dryopteris, D. marginalis is common in a variety of habitats and D. intermedia is usually found along the banks of shaded creeks and drainages be- coming most common on Pine Mountain. Dryopteris goldiana is associated with rich, sometimes rocky draw slopes of hol- lows. Also abundant on Pine Mountain and common locally in other parts of the county is Cystopteris protrusa, which is sparsely recorded in other areas of east- erm Kentucky (1). OTHER SPECIES OF NOTE Cheilanthes lanosa and Polypodium polypodioides are species which increase in numbers to the west and south of the eastern plateaus of Kentucky (1, 6). In 1 locality, within the city limits of Pike- ville, both are found on the same south- facing, exposed, sandstone-shale outcrop. While data are not available, Pikeville appears to be warmer than the outer parts of the county. The bedrock of Pike County consists mainly of shales and sandstones with sandstone caps and outcrops forming the resistant mountain ridges. The only oc- currence of limestone at the surface is on Pine Mountain where 2 major strata have been exposed due to faulting and uplift. Some species usually restricted to lime- stone have been found on sandstone sub- strates in the county. These include a col- ony of Woodsia obtusa approximately 10 m? in diameter. This extends the range of Woodsia obtusa into the eastern third of the state. Another limestone species, Pel- laea atropurpurea, was found growing on sandstone rock. In addition, 2 tufts of As- plenium resiliens were found in Pikeville on a sandstone outcrop. Approximately 300 m across the state line, in Dickenson County, Virginia, is a series of Polystichum acrostichoides which grades into a highly dissected P. acrostichoides f. multifidum. These plants were found in a mesophytic site. Note: Since the preparation of this manuscript, two additional species have been found in Pike County. These species are Selaginella apoda (L.) Spring ex Mart. and Trichomanes boschianum Sturm ex Bosch. Both were located near the Rus- sell Fork River of Breaks Interstate Park. ACKNOWLEDGMENTS Thanks to Dr. Warren H.

SMITH Department of Geology, Eastern Kentucky University, Richmond, Kentucky 40475 ABSTRACT The use of trend-surface analyses is wide spread in many disciplines. However, researchers need to statistically justify their selection of the trend that best fits the data of study areas. A relatively simple computer program, written in APL language, is presented to accomplish this task. The program uses total variance and amount of variance explained by each order surface to complete an analysis of variance table for each trend surface. In addition, model comparison between successively higher trend surfaces is completed to determine the statistical best fit. TREND-SURFACE ANALYSIS A trend is a statistically derived surface to explain variations in a given set of val- ues, known as Z-values, that have a given geographic position, either regularly or irregularly distributed in the x-y plane. The surface is the representation of an equation using the least-squares crite- rion. This means that the generated sur- face will be fitted to the input data in such a way that the sum of the squared devia- tions between the data at their particular locations and the corresponding value of the computed surface are minimized. Thus, the least-squares criterion calls for the surface to be laid down in such a way that the sum of the squares of these dis- crepancies is as small as possible, as in- dicated by: d? = E, where d? = deviation squared and E = minimum value. The basic reasoning behind minimiz- ing the sum of squares of the deviations, and not minimizing the sum of the ab- solute magnitudes of the discrepancies, are: 1. It is extremely difficult to mathe- matically deal with the absolute discrep- ancies or deviations; while the treatment of the squared deviations provides the method of practical mathematical de- velopments in the interpretation of the regression equation. 2. Useful and desir- able statistical properties follow from us- ing the least-squares criterion (1, 2, 3). The equation describing the surface can be linear (plane), quadratic (paraboloid), cubic (paraboloid with an additional point of inflection), to higher-order degree sur- faces. In general, the higher order of the surface, the more the residuals, or indi- vidual deviations, will be minimized and the more computation will be required. The higher-order trend surfaces may re- flect the variation in Z-values more ac- curately if the study area is complex, but lower-order surfaces may be more useful in the isolation of local trends. The filter- ing mechanism allows the upper limit of variability to be determined by the order of the surface. The equation for a linear trend surface, for example, is: Y = b, + b,X, + b.X:, where Y = dependent vari- able, b, = constant value related to the mean of the observations, b,b. = coeffi- cients, X,X. = geographic coordinates. This linear equation generates 3 un- knowns and 3 equations are needed to determine a solution. These equations are: (1) s Y = bon + by X, + by i=1 i=1 i=1 Q) > XY by > X, +b, y x2 i=1 i= + by S X,X., and i=1 (3) » XY — bo 3 eee > X,X> + bs > Xe i=1 where n = number of observations or data collected. Solving these equations simul- IEF 18 TRANS. KENTUCKY ACADEMY OF SCIENCE 44(1-2) TABLE 1.—TYPICAL ANALYSIS OF VARIANCE TABLE FOR POLYNOMIAL TREND SURFACES.

Of course, as the degree of the trend sur- face that is to be used increases, so does the number of equations that must be solved simultaneously. STATISTICAL ANALYSIS OF TRENDS According to Davis (4), the significance of a trend or regression may be tested by performing an analysis of variance, which deals with the separation of the total vari- ance of a set of observations into com- ponents with defined sources of varia- tion. In the case of trend-surface analysis, the total variance in an independent vari- able may be divided into the trend itself, which is determined by regression anal- ysis, and the residuals, or error vector. An analysis of variance table can be calcu- lated (Table 1). By reducing the sum of squares, which were derived from the least-square criterion, an estimate of the variance can be compared by using the F-distribution (4). The F-test, like a t-test, is a very robust test and relatively insen- sitive to violations of the assumptions of random selection of observations and normal distribution of the variables (5, 6). Newman and Fraas (7) and Nunnally (8) looked at a number of investigations that dealt with the F-distribution assumptions and their eventual violation, and summa- rized by suggesting that no appreciable effect on the accuracy of the F-test from non-normality of sample distribution oc- curred. In addition, if the sample sizes are equal, heterogeneity of variance has a negligible effect.

If the computed F-value exceeds the F-value having a probability of a set alpha level, commonly, .01 to .05, then the null hy- pothesis is rejected and an alternative hy- pothesis is accepted. According to Davis (4), in polynomial trend-surface analysis, it is customary for investigators to fit a series of successively higher degrees to the data without statistically testing the MODEL COMPARISONS OF TREND SURFACES—Smith 19 higher order’s contribution in additional variance. Davis further suggested that an analysis of variance table be expanded to analyze the contribution of the additional partial regression coefficients to give a measure of the appropriateness of in- creasing the order of the equations. How- ever, a standardized statistical technique was not developed by Davis that can be readily used by the nonstatistician. Therefore, a computer program was de- vised to calculate and present recom- mended procedure for analyzing poly- nomial trend surfaces. COMPUTER PROGRAM Table 2 represents a listing of the pro- gram source deck to complete the analy- sis of data related to trend-surface anal- ysis. The program, written in APL, can easily be adapted to almost any system with an APL compiler. The program was originally designed for an interactive mode, but with a few revisions in the pro- gram it can be adjusted to read in a batch mode. The required input is the total variation of the data, and the amount of variance accounted for by the order sur- face. This information is generated by most computer software packages that produce trend surfaces, such as SYMAP (9) and SURFACE II (10). Table 3 illustrates the printed output of a successful execution of the program. The program not only completes an anal- ysis of variance table for each trend sur- face, but also completes model compari- son to determine if the use of a higher degree surface produces a statistically significant increase in amount of variance explained by the trend surface to warrant its use. Specifically, the example out- lined in Table 3 shows that all 3 trends are not statistically significant at the .05 level, and no higher order trend is statis- tically better than its lower-order coun- terpart. Technically, the degrees of freedom used in the F-test utilizes the following: df, = m, — m,, df; = N — m, where df, = degrees of freedom-numerator, df, = de- grees of freedom-denominator, m, = number of coefficients, counting the con- TABLE 3.—EXAMPLE INPUT AND OUTPUT OF AN ANALYSIS OF TREND-SURFACE DATA.

These equations, determined by Newman and Thomas (11) are similar in function to those equations suggested by Davis (A), except the addition of the constant term, b,. In the case of trend-surface analysis, m, corresponds to the number of coeffi- 20 cients, including the constant b, in the higher-order surface, while the term m, is associated with the number of coeffi- cients, plus the constant term, in the low- er-order surface. For example, in a sec- ond-order trend surface, the equation is represented by: Y = b, + b,X, + boX. + bX,? + byX.? + bsX,Xo. In hypothesis testing to determine if this second-order equation is statistically significant at a set alpha level, this equa- tion becomes the full model, since it con- tains all the required terms and their coefficients. The restricted model is defined as no information, since an in- vestigator is asking the question if the second-degree surface is predictive of the geographical distribution of the data over no other trend surface. Thus, m, equals 6 and m, equals 1, which is the constant term common in both models. Ifa sample size of 25 is assumed, the degrees of free- dom-numerator are equal to 6 minus 1, or 5; and degrees of freedom-denominator are equal to 25 minus 6, or 19 (Table 3). The regression sum of squares term is calculated by the amount of variance ex- plained by the trend surface, which is re- quired as input into the program. The re- sidual sum of squares term is calculated by substracting the variance explained from the total variance, which is also re- quired as input, to arrive at the variance unaccounted for by the trend surface. The mean sum of squares for each term is, in turn, calculated by dividing the corre- sponding degrees of freedom, and the re- sulting ratio of these two mean sum of squares yields an F-value. By comparing this F-value with a tabulated F-ratio for a selected alpha level, found in most sta- tistical tables, a decision on statistically accepting or rejecting the trend surface can be made. The completion of this analysis of variance in the format shown in Table 3 is the function of the subrou- tine, Report 1 (Table 2). In addition, model comparison be- tween trend surfaces is also completed by the function of subroutine, Report 2. The model comparison directly answers the major question of determining the or- TRANS. KENTUCKY ACADEMY OF SCIENCE 44( 1-2) der of best fit previously proposed by Da- vis (4). In the case of trend-surface anal- ysis, the full model corresponds to the higher-order trend surface; and the re- stricted model corresponds to the lower- order trend surface, or 1 order less than the order in the full model. Again, the degrees of freedom and resultant F-value are reached as previously defined. Hence, an investigator can determine, by use of this computer program, the trend surface that statistically best fits geographically distributed data. SUMMARY The relatively simple computer pro- gram presented here utilizes ANOVA techniques to help researchers make a more effective and statistically sound de- cision in the selection process involved in trend-surface analyses. The author rec- ommends that this test should be rou- tinely used in geophysical and sociolog- ical surveys involving analyses of trends and their prediction.

Additions to the Distributional List of Kentucky Trichoptera: Big Sandy River (Boyd County); Pond Creek and Scenic Lake (Henderson County)! KIM H. HAAG AND PAuL L. Hin Department of Biology, University of Louisville Louisville, Kentucky 40292 ABSTRACT Adult caddisflies were collected from the Big Sandy River in Boyd County, and from Pond Creek and Scenic Lake in Henderson County, Kentucky. A total of 40 species in 7 families were identified, including 4 new state records: Pycnopsyche indiana (Ross), P. luculenta (Betten), P. scabripennis (Rambur), and Ironoquia lyrata (Ross). Occurrence of I. lyrata in Kentucky rep- resents a southern range extension in North America. INTRODUCTION The caddisflies of Kentucky have been thoroughly examined in a few drainages only, and many areas remain unstudied in the state. Resh (1) compiled the first distributional list of Trichoptera in Ken- tucky, relying on his own collections as well as those from universities through- out the region. No species were listed from Boyd County, while only Potamyia flava and Ceraclea maculata were re- ported from Henderson County. This pa- per presents the results of collections of adult caddisflies from the Big Sandy Riv- er at Ashland, in Boyd County, and from Pond Creek and Scenic Lake, in Hen- derson County. A total of 40 species in 17 genera were identified, representing 7 families. RESULTS Big Sandy River The Big Sandy River and its tributaries drain southeastern Kentucky and south- ‘University of Louisville, Department of Biology Contribution No. 203. western West Virginia. The stream joins the Ohio River at Ashland, Kentucky (ORM 322.6) and has a mean summer dis- charge of 1,965 cfs. Water-quality data were published by the U.S. Geological Survey (2). Caddisfly adults were collect- ed qualitativ ely at several outdoor lights on the property of the Ashland Oil Com- pany, from 14 June to 9 October 1973. A total of 350 specimens were taken during the summer, including 28 species refer- able to 5 families (Table 1). While most of the individuals taken represent county records, the species Ironoquia lyrata, Pycnopsyche indiana, P. luculenta, and P. scabripennis are new state records. The occurrence of I. lyrata (Ross) in Ken- tucky represents a southem range exten- sion for the species, previously known only from Illinois and Pennsylvania (3), New Hampshire (4), Maine (5), and northern Ohio (6). The family Hydropsychidae was nu- merically dominant, and emergence of adults spanned the entire season. Cheu- matopsyche pettiti, the most abundant species, emerged throughout the sum- 22 TRANS.

Mem- bers of the Leptoceridae also showed an emergence pattern which extended through the entire summer. Congeneric species in this family did not appear to show temporal segregation. Although limnephilids were found in low num- bers, their emergence patterns did sug- gest temporal isolation of congeners. Pycnopsyche indiana was found only in CADDISFLIES IN KENTUCKY—Haag and Hill 23 mid-June while P. scabripennis was present in a late August collection, and P. luculenta was seen only in late Sep- tember and early October. However, Ironoquia lyrata and I. punctatissima were found in low numbers in both mid- June and late September. Scenic Lake, Audubon State Park Blacklight trap collections were made on 14 June 1981 near a small unnamed creek which drains Scenic Lake. This man-made lake is the largest body of water within the John James Audubon State Park, just outside the city limits of Henderson, Kentucky. The small, wood- land stream that drains Scenic Lake flows into the Ohio River approximately 2.4 km downstream from the collection site. A total of 294 specimens were collected, in- cluding 18 species in 5 families. Pota- myia flava, commonly found in large rivers, was the most abundant species taken, suggesting that the light trap was attracting caddisflies emerging from the nearby Ohio River. Oxyethira pallida, the second most abundant species, is known to live in small lakes and ponds such as Scenic Lake (8). Pond Creek, Jenny Hole Wildlife Area Insects were collected from Pond Creek in the Jenny Hole Wildlife Area on 27 July 1981, using blacklight traps. Pond Creek is the primary drainage stream for the entire Henderson Sloughs Wetlands in western Henderson County. The un- dulating terrain of the area provides an unusual habitat of marshes, streams, and cypress swamps. Pond Creek is a slug- gish, heavily silted tributary of Highland Creek that flows into the Ohio River at Uniontown, Kentucky. The small collec- tion of 43 adults, including 8 species in 3 families, may reflect the high turbidity, low dissolved oxygen, and generally un- favorable conditions of surface waters in this area (9).

STUART Department of Biological Sciences, Murray State University, Murray, Kentucky 42071 ABSTRACT Two hundred ten clinical isolates of Streptococcus pyogenes were tested for constitutive and inducible resistance to penicillin, tetracycline, erythromycin, lincomycin, chloramphenicol, and gentamicin. Of the 210 isolates tested by the disc-plate method, 71 appeared resistant to at least 1 of the antibiotics although none of these isolates were resistant to chloramphenicol. Minimal inhibitory concentration testing revealed that 48 isolates were resistant to tetracycline (16.2%), lincomycin (1%), erythromycin (6.2%), gentamicin (2.4%). No isolates were resistant to penicillin or chloramphenicol. Also, no inducible antibiotic resistance was noted. Twenty of 210 isolates exhibited minimal inhibitory concentrations above the average serum level for tetracycline (15.7%), erythromycin (0.5%), lincomycin (1.0%), or gentamicin (2.8%). The clinically resistant isolates were screened for the presence of extrachromosomal DNA by gel electrophoresis but no plasmids were detected. Efforts to cure several antibiotic resistant strains were unsuccessful. The physical and genetic evidence indicated a chromosomal location for genes mediating antibiotic resistance of the isolates examined in this study. INTRODUCTION Surveys of antibiotic sensitivity of group A streptococci have been reported from the U.S. (1, 2) as well as from a number of other countries (3, 4, 5), with the most extensive work being done by Dixon and Lipinski (6) in Canada. In several in- stances (7, 8), antibiotic resistance in Streptococcus pyogenes has been shown to be a plasmid-mediated phenomenon. To date, 6 plasmids have been described (7, 8, 9, 10) which mediate macrolide, lin- comycin and streptogramin B (MLS) re- sistance in this species. Inducibility of antibiotic resistance in S. pyogenes, first reported by Hyder and Streitfeld (11), is a property associated with 5 of the 6 plasmids mentioned above. Thus, a pattern seems to be emerging whereby the MLS genotype is usually plasmid borne and inducibly expressed. A question which remains to be an- swered in S. pyogenes is: what is the in- cidence of plasmid-bome antibiotic resis- tance among clinical isolates resistant to one or more antibiotics? Data provided in this report indicate that plasmid-borne antibiotic resistance is uncommon among group A streptococci isolated in Ken- tucky. MATERIALS AND METHODS Bacterial Strains.—Clinical isolates of Streptococcus pyogenes were supplied by the Kentucky Bureau for Health Services (184 isolates) compliments of G. Kilgore and by the Student Health Service of Murray State University (26 isolates). All isolates were obtained from throat cul- tures processed from approximately Fall 1978 through January 1980. Streptococcal isolates were grouped by the fluorescent- antibody method at the Kentucky Bureau for Health and by the bacitracin-disc technique at Murray State University Student Health Service. Following iden- tification of each isolate as a group A streptococcus, the culture was received and analyzed as described below. Anti- biotic-sensitive control strains included 9440 and K56 (12). Plasmid-containing control strains included a group A strain, ACI, obtained from Clewell and Franke (8) and a group B strain MV154 described by Hershfield (13). Media.—The standard (YTH) broth medium consisted of Todd Hewitt broth (Difco) supplemented with 0.6% Yeast Extract (Difco) plus 0.038% K,;HPO,. YTH agar consisted of YTH broth with 1.5% agar. 24 ANTIBIOTIC SENSITIVITY IN STREPTOCOCCI—Christopher et al. Antibiotics.—These were obtained in powder form from Sigma except lincomy- cin which was obtained from Upjohn as the injectable hydrochloride. Disc Plate Screening.—Two ovemight cultures of each isolate were cultivated, one in YTH broth and one in YTH broth containing subinhibitory concentrations of the 6 antibiotics tested. One tenth ml aliquots from each overnight culture were spread on the surface of YTH agar plates. Paper discs (Difco) individually impreg- nated with penicillin (5 units), erythro- mycin (2 wg), lincomycin (2 wg), tetracy- cline (5 wg), chloramphenicol (5 wg), and gentamicin (10 wg) were applied to each agar plate. The agar plates were incubat- ed at 37°C for 24 hours, and zones of growth inhibition measured and record- ed in mm. The inhibitory zone diameters for each antibiotic against the control strains (K56 and 9440) were averaged, and those test isolates that had zones of in- hibition less than % the control zone were considered presumptively resistant (pr). Minimal Inhibitory Concentrations.— Each pr isolate was tested for the mini- mal inhibitory concentration (MIC) by a microtiter dilution technique adapted from Baker and Thomsberry (14). Each isolate was grown overnight as before in YTH broth and in YTH broth containing subinhibitory concentrations of the anti- biotic(s) to be tested. Each overnight cul- ture was diluted 1/100 in YTH broth, then distributed in 25 yl aliquots to wells of the microtiter dish. Previous to the in- oculation of bacteria, 50 ul of YTH broth supplemented with the appropriate anti- biotic were added to the first well and doubling dilutions were made. Strains K56 and 9440 served as sensitive controls and the average MIC for each antibiotic was determined. Test isolates with MICs 16 times the control average were consid- ered resistant. Criteria for inducibility were set at the same level (i.e., inducibly resistant strains showed at least 16-fold difference between pre-induced and non- induced cultures). Clinically resistant strains possessed MIC values higher than the average human serum level for that antibiotic. 25 DNA Isolation.—Cell lysis was accom- plished by a procedure described by Forbes and Ferretti (pers. comm.). Anti- biotic resistant strains were cultivated at 37 C in 200 ml of YTH broth containing antibiotics to which each strain was re- sistant at a concentration of 4% the MIC value. Penicillin G (110 units/ml) was added to late log-phase cells and incu- bation continued for 2 hours. Cells were then harvested by centrifugation and the pellet frozen before use. The pellet was resuspended in 5 ml of 0.15 M Trizma (Sigma) base-HCl at pH 6.4 containing 4 mg of lysozyme (Natl. Biochem. Corp.) and 5 ml of 0.25 M EDTA and the sus- pension was incubated at 37°C for 3.5 hr. The cells were then pelleted and resus- pended in 10 ml of 0.1 M sodium citrate, plus 0.8 ml of a 5% solution of protease (Sigma type V) with overnight incubation degraded the remaining proteins and en- hanced cell lysis. The method of separation of chromo- somal DNA from plasmid DNA was es- sentially that described by Currier and Nester (15). Gel Electrophoresis.—Gel electropho- resis of the experimental and control (ACI and MV154) DNA was accomplished by the method of Sharp et al. (16). Both tube gels (Buchler) and slab gels (Savant) were used for the separation and visualization of plasmid DNA. Ten or 20 wg of each DNA preparation was layered on the slab and tube gels, respectively. Curing Methods.—Four plasmid cur- ing methods were utilized: (a) storage of the isolates on blood agar slants at 4°C for at least 6 mo., (b) incubation of isolates with subinhibitory concentrations of ethidium bromide in YTH broth at 37°C for 24 hr, (c) incubation of the isolate at an elevated temperature (42°C) in YTH broth for 18 hr (13, 8) and (d) incubation at a high temperature (45°C) for an ex- tended period (2-3 weeks) according to Clewell et al. (17). RESULTS Disc Plate Screening.—Of the 210 iso- lates tested, 71 exhibited presumptive re- sistance to at least one antibiotic by this 26 TABLE 1.—PERCENTAGES OF ANTIBIOTIC RESIS- TANT GROUP A ISOLATES DETERMINED BY THE MIN- IMAL INHIBITORY CONCENTRATION METHOD Jo* Resist- Antibiotic ance r/pr x 100 Penicillin 0% 0% Erythromycin 6.2% 86.7% Lincomycin 1.0% 40.0% Tetracycline 16.2% 70.8% Gentamicin 24% 29.4% Percentages of Multiply Resistant Group A Isolates J Resis- Antibiotics tant r/pr x 100 Gentamicin, Tetracycline 1.0% 33.3% Erythromycin, Lincomycin 1.0% 100% Erythromycin, Tetracycline 0.5% 100% Erythromycin, Gentamicin, Tetracycline 0.5% 100% * Per cent based on 210 isolates tested. method. No isolates demonstrated resis- tance to chloramphenicol. Resistance to penicillin, erythromycin, lincomycin, tet- racycline, and gentamicin was demon- strated by 3, 15, 5, 48, and 18 isolates, respectively. MIC Testing.—Seventy of the pr iso- lates (1 stock was lost) were quantitated for antibiotic sensitivity. Although no pr isolates were noted exhibiting chloram- phenicol resistance, 24 isolates were cho- sen for MIC testing. Percentages of resis- tant isolates are presented in Table 1. No inducible resistance was exhibited by any isolate tested by the MIC method. The largest category of resistance included those isolates resistant to tetracycline (16.2%), whereas no pr isolates were TRANS. KENTUCKY ACADEMY OF SCIENCE 44(1—2) found to be resistant to penicillin by this method. The best agreement between disc-screened resistance (pr) and MIC testing (r) was observed with erythro- mycin testing. Multiple resistance was confirmed in 6 isolates with the MIC procedure (Table 1). Five of the isolates were doubly re- sistant, whereas 1 isolate exhibited resis- tance to 3 antibiotics. Table 2 presents MIC ranges and me- dians compared to average serum levels of the 6 antibiotics tested. The highest level of clinical resistance (15.7%) was noted among the tetracycline resistant isolates. No strains were clinically resis- tant to chloramphenicol or penicillin, al- though 1 strain exhibited clinical resis- tance to erythromycin. Gel Electrophoresis.—With the excep- tion of 6 strains lost from culture, the clin- ically resistant strains plus 12 additional erythromycin resistant strains were sub- jected to DNA isolation procedures and gel electrophoresis. Figure 1 shows the control strains AC] and MV154 with the characteristic chromosomal and plasmid bands of DNA compared to 8 experimen- tal strains and plasmid negative 9440. No plasmids were detected in any of the clinical isolates tested with tube or slab gels. Curing.—Several clinical isolates and the positive plasmid control strain ACI were subjected to a variety of curing pro- cedures shown in Table 3.

Ten M. pennsyl- vanicus were taken at 5 of the 25 field- points. Capture points had a lesser per cent canopy cover (P < 0.001), and they were farther from trees (P < 0.005) than points without captures. Capture points also had lower evergreen ground cover (P < 0.0001), and denser herbaceous ground cover (P < 0.001) than non-cap- ture points. Correlations between the number of captures per point and habitat variables influencing captures were more difficult to make because of the small sample size and the positions of points where cap- tures were made (Table 2). Variables measuring stratification of vegetation at the points, canopy cover (P < 0.001) and foliage height diversity (P < 0.001), were negatively correlated with M. pennsyl- vanicus captures. Captures were also negatively correlated with the following variables characteristic of woods: density of woody stems (P < 0.05), number of woody stems (P < 0.05), percentage of evergreen herbs (P < 0.05), and ground cover (P < 0.01). Other Species.—Three other species of small mammals were captured during this study: P. leucopus, B. brevicauda, and M.

Peromyscus leucopus was captured 15 times during the study, 6 times during the first capture period and 9 times during the second period. Blari- na brevicauda was taken 11 times, 8 dur- ing the first sample period and 3 in the second period. Only 3 M. ochrogaster were captured, all during the second pe- riod, and all were taken in the field. Peromyscus leucopus has been char- acterized as a species preferring a shrub- land-woodland habitat (5, 10), but we caught more P. leucopus in the field than in the woods. The per cent canopy cover 2, TRANS. KENTUCKY ACADEMY OF SCIENCE 44(1-2) was the only variable that showed cor- relation with capture (P < 0.05) in both sample periods. The points where P. leu- copus were taken in the field indicated its preference for trees since every cap- ture site was within 8 m of a tree. Blarina brevicauda was an ubiquitous species that showed no preference for a specific type of vegetation. They have been taken in vegetation types ranging from grasslike to forested (11, 12). Cap- tures of B. brevicauda were positively correlated with log length (P < 0.05), probably because invertebrates could be found in greater numbers there. Only 3 M. ochrogaster were taken dur- ing the study. However, these 3 captures substantiated the available literature on the prairie vole; it is a species of grassy fields (7, 13, 14). DISCUSSION Microtus pinetorum captures were cor- related with tree variables, reflecting the predominance of captures in the woods. They occurred at sites with thick canopy cover, adjacent trees, and high tree species diversity and showed preference for sites of vegetative strata diversity. Life forms of vegetation influenced selection of habitat by M. pinetorum. Variables that consider life forms rather than taxa have been shown to be most important in M. pinetorum habitat selection (8). This species preferred sites with a preponder- ance of evergreen vegetation. Woody and herbaceous plants have more water avail- able during the growing season than grasses. Benton (15) reported that M. pi- netorum is not dependent on water to any degree in nature; the species thrives in captivity without water if succulent food is supplied. It is reported to feed on suc- culent roots and tubers in nature (1). Mi- crotus pinetorum also occurred at sites with fallen logs. Log diameter, density, and distance were important habitat fea- tures. Microtine runs were observed along fallen logs; M. pinetorum will nest under fallen logs (13). Microtus pennsylvanicus segregated itself from M. pinetorum by its selection of field characteristics, occurring at sites with dense grass. Many studies have shown M. pennsylvanicus to prefer grass- like herbaceous cover (6, 9, 16, 17), while avoiding areas where woody plants pre- dominate (18). The number of captures of other species was low, but general trends were dis- cerned. Peromyscus leucopus showed a preference for points with trees in the vi- cinity, Blarina brevicauda showed a preference for long logs; and M. ochro- gaster preferred grassy habitats. The results of this study indicate that habitat characteristics selected by small mammals in an urban woodlot were sim- ilar to characteristics reported in pre- vious studies for each species in rural areas. The location of the woodlot in an urban environment had no obvious effect on habitat selection by indigenous small mammals. Shady Lane Woods offers unique opportunities to study sympatric small mammal species in an urban set- ting because of its diverse habitats and high species richness of small mammals.

However, if certain complex problems, such as the 3-dimensional geometry of a rock mass, are to be solved graphically, then the use of the stereographic projection or stereonet is essential (Ragan, Structural geology: An introduction to geo- metrical techniques, 2nd ed., John Wiley & Sons, 1973). With a large number of scattered points, the problem of treating and evaluating the data arises. Thus, the statistical evaluation of orientational data with the aid of a digital computer is certainly des- tined to be an increasingly important approach (Cruden and Charlesworth, G.S.A. Bull. 83:2019- 2024, 1972; Watson, Bull. Geol. Inst. 2:73-83, 1970). The evaluation of plotted data requires a special type of net, since the resulting distribution plotted on the usual Wulff net would not be statistically random. To overcome this difficulty, an equal area of the Schmidt net is used, since, for many appli- cations in structural geology, it is convenient to use a projection that does not distort area. Once the point diagram is prepared, the densities are counted out. A wide range of graphical counting methods have been developed (Denness, Geol. Mag. 109:157-163, 1972; Hobbs, Means, and Williams, An outline of structural geology, John Wiley & Sons, 1976; Stauf- fer, Canadian Jour. Earth Sci. 3:474-498, 1966). In an attempt to illustrate a graphical counting method, approximately 400 stike and dip readings were taken in an area of the Shenandoah Valley region, Virginia, and plotted on an equal area pro- jection. SYMAP (Dougenik and Sheehan, SYMAP users reference manual, Harvard Univ., 1979), which is a computer package designed for the purpose of producing line-printer maps to depict spatially dis- PARTIAL PLOT OF SHENANOOAH VALLEY tributed data, was used to contour the point densi- ties and create an 89 x 89 digital data matrix of this information on a tape file. This data file was then fed into a three-dimensional plotting program using the following options: QUSMO2, which performs a 9-point quadratic interpolation between points to give a smooth appearance (Fig. 1); and QUTAB, which produces a plot similar to a three-dimen- sional histogram (Fig. 2) (Sawan and Nash, Three- dimensional mapping programs user manual, Univ. of Akron, 1974). Both figures display the same in- formation, and the plots can be rotated in 8 direc- tions; this more dramatically presents structural in- formation than the traditional 2-dimensional contour diagram. SYMAP, QUSMO2, and QUTAB are commercially available and require no previous programming ex- perience or knowledge. Both SYMAP and SUR- FACE II (Sampson, Surface II graphics system, Kan. Geol. Survey, 1979), the counterpart to QUSMO2, are presently available to interested persons through the University of Kentucky as well as several other academic computing centers—Alan D. Smith, Dept. Geol., East. Ky. Univ., Richmond, Kentucky 40475. New Species Records of Caddisflies (Trichoptera: Hydropsychidae) in Kentucky—Two species of caddisflies are added to the list of species known from Kentucky: Hydropsyche frisoni Ross and Symphitopsyche slossonae (Banks). Hydropsyche frisoni larvae were collected on 6 June 1979 from Crooked Creek, 3 August 1979 from Browne Fork of Skeggs Creek, and on 14 August 1979 from the Rockcastle River in Rockcastle County. Symphito- psyche slossonae larvae were collected on 5 Sep- tember 1979 from Horse Lick Creek and from Clo- ver Bottom Creek, and again on 6 June 1979 from Horse Lick Creek in Jackson County. Specimens were identified by means of the keys and species descriptions provided by Schuster and Etnier (USEPA Publ., EPA 600/4-78-060, 129 pp., - 1978) and were confirmed by Dr. G. A. Schuster, Eastern Kentucky University. These records sup- plement the list of Kentucky Trichoptera (Resh, Trans. Ky. Acad. Sci. 36:6-16, 1975), and bring the current Commonwealth total to 177 species. Hydropsyche frisoni is known from Illinois, Michigan, Tennessee, Alabama, and Minnesota (Ross, Bull. Ill. Nat. Hist. Surv. 21:101-183, 1938; Ross, Bull. Ill. Nat. Hist. Surv. 23, 326 pp., 1944; Leonard and Leonard, Occ. Pap. Mus. Zool. Mich. 522:1-35, 1949; Etnier, J. Ga. Ent. Soc. 8:272-274, 1973; Schuster and Etnier, 1978). Symphitopsyche slossonae has a much broader known range, ex- tending over the northeastern sections of the United States and Canada. The discovery of these 2 species in Kentucky was not surprising considering their known distributional ranges, and more intensive collecting in the area would probably increase the total for Trichoptera in Kentucky. 74 NOTES 75 We thank Dr. G. A. Schuster for confirming the identification of the specimens.—William T. Thoeny, Dept. Entomol., Univ. Ky., Lexington, Kentucky 40506 and Donald L. Batch, College Nat. and Math. Sci., East. Ky.

Suggested Format for Presenting Hypothesis Testing and Model Comparisons of Trend Sur- faces.—Trend-surface analysis is the term for a mathematical method of separating map data into two components, regional and local (Davis, Statis- tics and data analysis in geology, John Wiley and Sons, Inc., New York, 1973). Hypothesis testing and model comparisons of successively higher order trends are important in this process. The signifi- cance of a trend, or regression, may be tested through the analysis of variance, which separates variance into components with defined sources, or through the F-test which explores the null hypothesis that par- tial regression coefficients are equal to zero and, hence, there is no regression. In polynomial trend- surface analysis, it is customary for investigators to fita series of successively higher polynomials to the data without justifying their contribution of addi- tional explained variance over the previous lower order trend. As demonstrated elsewhere (Smith, Trans. Ky. Acad. Sci. (abs.) 43(1-2):93, 1982), an analysis of variance table should be expanded to analyze the contribution of the additional partial regression coefficients to give a measure of the ap- propriateness of increasing the order of the equa- tion. Hypothesis testing and model comparisons to evaluate higher order trends are relatively recent statistical procedures, not fully practiced by re- searchers using trend surface analysis techniques. A standardized format to present the data generated from these procedures is needed. Table 1 illustrates data for a fourth-degree polynomial trend surface with random variation. The terms in the table are esential to the development and understanding of the statistical results to evaluate the explained vari- ance of the additional partial regression weights. Model 4 represents the fourth-degree surface with its related statistics: degrees of freedom, both in the numerator and denominator (df); amount of vari- ance accounted for by the regression equation (R’); set decision criterion (alpha); F-ratio; probability of the F-ratio (P); and significance (NS or S). Model 99 shows a restricted model displaying simple ran- dom variation, noted by the constant term, ayU, and residual vector, E. Table 2 illustrates the results of determining if additional variance accounted for by a third-degree surface trend is significant enough to warrant its use over and above the variance ac- counted for by a second-degree surface. Lastly, Ta- ble 3 lists a summary of F ratios, probability levels, R? for both the full and restricted models, degrees of freedom for both numerator and denominator, and significance for each trend surface. This table con- denses 11 separate tables in the hypothesis testing and model comparisons process. The tables presented here are an attempt to dis- play, in an organized and selective fashion, the rel- atively large amount of information associated with a detailed statistical analysis of trend surfaces.

Jarnette, a graduate student in the Biology Dept., Univ. of Louisville, brought to one of our offices (F.H.W.) 2 living female specimens of Paragordius sp., 1 of which was ovipositing. The worms and egg string were placed in a container with aquarium water and observed for about 5 weeks, until the worms died. The adults were preserved in 70% ethanol, and the egg string was refrigerated at 4°C. The egg mass was subsequently examined on 4 occasions over 11 weeks for emerging and motile larvae. At no time was there any detectable swelling of the egg string. During the fourth week, before re- frigeration of the egg string, thousands of hatched larvae were observed on the bottom of the culture dish. Very few of these showed any movement. Al- though not motile, some larvae were in the process of emerging from the eggs (Fig. 1). Terminology of Fig. 1 is of Dorier (Trav. Lab. Hydrobiol. Piscicult. NOTES la Fic. 1.

The most signicant results of this study were observa- tions of larval movement and emergence during each of the 4 times the egg mass was examined following the latter’s refrigeration for 11 weeks. There was no information from the available lit- erature regarding the length of time larvae continue to hatch from eggs. The 11 weeks we recorded for the larvae of Paragordius sp. are probably not un- usual for nematomorphs. Such extended hatching in nature would more effectively ensure the pres- ence of infective larvae whenever hosts become available in the immediate area. This spatial and temporal relationship would have definite survival value for the nematomorphan species, since the lar- va probably does not survive long after hatching. Basically, the larva is the infective stage for the arthropod host in which it transforms to the parasitic juvenile. Upon emergence, the juveniles rapidly mature to free-living adults which mate. From one to several million eggs are eventually deposited by each female (Cheng, Gen. Parasitol., Academic Press, 965 pp., 1973). Various modifications of how the larva enters the host exist; for example, larvae of Gordius aquaticus encyst and are perhaps in- gested (Dorier, 1930), while larvae of G. robustus and Paragordius varius penetrate the host (May, II. Biol. Monogr. 5:1-118, 1919). A third condition is the larva of Chordodes japonensis which emerges from the egg, does not encyst, but must be ingested by the host (Inoue, Jap. J.

Note on Kentucky Riffle Beetles —Distribution of the 3 families of aquatic insect usually called riffle beetles, i.e., Dryopidae, Psephenidae, and Elmi- dae, is very poorly known in Kentucky, hence the reason for this note. The following specimens were collected from Mud Creek, 4 km above the mouth, Madison County, Kentucky; 17 September 1970: 1 adult female Helichus lithophilus (Dryopidae), 12 immature Psephenus herricki (Psephenidae), 8 adult Stenelmis sexlineata (Elmidae). Dr. Harley P. Brown, foremost American authority on riffle bee- tles, diagnosed the specimens. He is anxious to ob- tain specimens from Kentucky and is willing to pro- vide specific diagnoses.

After a motion by Secretary Creek and a second from the floor, the minutes of the 1981 annual busi- ness meeting at Murray State University, as record- ed in the Transactions Vol. 43(1-2), were approved. Secretary Creek made a motion that all new mem- bers for 1982 be accepted by the Academy. Follow- ing a second from the floor the motion passed. Dr. Creek said that only about 50 percent of the mem- bership had paid their 1982 dues and thus received the September issue of the Transactions. He point- ed out that in order to receive the 1983 Transac- tions the 1983 dues must be paid by February 1, 1983. The Treasurer's report was made by Dr. Taylor.

The Board of Directors met twice this year and was primarily concerned with revising the By-laws of the Foundation. It was decided to merge the Flo- ristic Survey Grant with the Botany Foundation af- ter dispersement of the Grant’s current funds. The Botany Foundation will be changed to the Botany Research Fund in order to prevent confusion with the K.A.S. Foundation. The possibility of hiring an Executive Secretary to handle the financial matters of the Foundation 78 ACADEMY AFFAIRS was discussed by the Board. Although it was con- sidered to be a good idea the Board decided it was not feasible at this time due to inadequate funds but should be reconsidered as funds became avail- able. A committee composed of Joe Winstead, Herb Leopold, and William Baker is in the process of developing guidelines for handling the foundation funds. When these and the By-law revisions are fi- nalized, a copy will be sent to K.A.S. members. Also under consideration are ways to obtain do- nations for the Foundation. One suggestion is to develop a brochure that would show what the acad- emy is, what it has accomplished, and what it pro- poses to do with money donated to the Foundation. Another consideration is the possibility of re- questing from the state legislature a large one time donation which would be invested in the money market, the interest of which would be used in var- ious ways such as employing an Executive Secre- tary or toward publishing the Transactions. The other remaining business transacted by the Board was the selection of the recipient of the Dis- tinguished Scientist Award for the current year. 2. COMMITTEE ON PUBLICATIONS. Dr. Bran- ley Branson made the following report. 1. Volume 43(1-2), March 1982, consisted of 96 pages that included 12 papers, Academy Affairs, Program, Abstracts of some of the papers presented at the 1981 annual meeting of the Academy, and News and Comments. Volume 43(3-4), 97 pages, included 16 papers, Guidelines for Preparation of Abstracts, Format Changes for the Transactions, Academy Affairs, and the Annual Index. The cost for printing 43(1-2) was $5,998.09 and that for 43(3- 4) was 5,490.39 for an annual total of $11,488.48, an increase of $913.17 (7.95%) over the cost for Volume 42. The percentage increase was roughly 7.5% less than that of the previous year, mostly because of a $446.87 savings in labor charges, materials costs, and mailing associated with revision of the mailing list. The actual increase was associated with the publication of a few more papers than in 1981. Ad- ditional savings are anticipated because of the re- cently applied format changes (see Transactions 43(3-4) and the elimination of blank pages in the journal; the effect of these changes will not become obvious until publication of 44(1-2). There was an actual decrease in cost of printing per page from 1981 to 1982 amounting to approximately $1.50. However, Volume 43 was 20 pages longer than Vol- ume 42. The subjects of the 28 papers in Volume 43 were distributed among 4 disciplines as follows: General, 1 paper; Zoology and Entomology, 17 papers; Bot- any and Microbiology, 9 papers; Geology and Ge- ography, 1 paper. 2. Because of the precarious financial situation now extant, the Editor has recently entered into a discussion with the Allen Press, and he has suc- cessfully convinced the press of our problem. Allen Press has agreed to bill us for the production of the 79 journal in 1983 at the same price they charged us in 1981, thus giving us a degree of price stability. However, I have been informed that we should plan for a price increase in 1984. In view of this, I have conducted a brief survey of other academies of science with regard to finan- cial plights and their dues structure. The Kentucky Academy of Science is at present charging members far less than many other academies of comparable size and quality. For example, the Kansas Academy of Science charges members $16.00, students $10.00, and libraries $20.00. The North Carolina Academy of Science charges members $16.00 and libraries $30.00 with no special class for students ($16.00). The Oklahoma Academy of Science changes mem- bers $20.00, students $10.00, and libraries $30.00. We must increase our dues by $5.00 in order to bring our dues structure in line with those charged by other organizations in order to partially amelio- rate our financial problems. As mentioned previously, the format changes, the installation of a note format, and the publication of abstracts of papers presented at the annual meet- ings will help our income picture somewhat. How- ever, this is only a partial solution. 3. As reported by the research section of the Allen Press to your Editor, before a society can have a stable or growing membership structure, six to twelve per cent new members must be added each year. Not only are we not accomplishing that, we have actually been losing membership. We must make a intensive attempt to pull all the scientific forces of Kentucky into the Academy of Science. If we could accomplish that goal most of our financial problems would virtually vanish. It is pathetic to realize that the Academy membership includes such a small percentage of Kentucky scientists. 3. COMMITTEE ON LEGISLATION. Dr. Charles Kupchella presented the report. Dr. Kupchella said that the committee had no for- mal action upon which to report. There was con- cern, however, about the formula for funding of higher education being considered by the Council of Higher Education. He said that this was an area that should be followed closely because of the pos- sible implications it would have in the science field. 4. COMMITTEES ON DISTRIBUTION OF RE- SEARCH FUNDS. (1) The Botany Research Fund report was made by Dr. Joe Winstead. Applications are being received for the 1983-84 year with the deadline for funding requests being 1 April, 1983. Since the inception of the $10,000 endowment in 1978 six student research proposals have been funded with a total expediture of $2,043 from the earnings. It is anticipated that available funding for 1982- 83 will exceed $1,400. (2) Floristic fund—No report. 80 TRANS. KENTUCKY ACADEMY OF SCIENCE 44(1-2) 5. SCIENCE EDUCATION ADVISORY COM- MITTEE. Ms. Anna Neal made the following re- port. Ms. Neal reported that the brochure concerning careers in science which was being developed by the committee had been put on hold this past year due to the involvement of the committee in the cri- sis developing in teacher education in science. She reported that as a result of attending the AAAS meeting in Washington D.C. on science and math- ematics education she felt more positive toward the future of science education. She said she has been contacted by Auburn University about the possibil- ity of the Academy participating in a southeastern regional conference to further discuss the problem. She reported that following her AAAS meeting she has had many inquiries about the scholarship-loan program that Kentucky has recently made available. Ms. Neal also reported that the State Science Ad- visory Board was being reformed which was the result of action taken by Raymond Barber. The council will report directly to Mr. Barber. 6. KENTUCKY JUNIOR ACADEMY OF SCI- ENCE. Mr. Herb Leopold made the following re- port. Our annual symposium was held at Western Ken- tucky University on April 23-24, 1982. Thirty-one papers were entered from 8 schools. Our speaker was Dr. Thomas Coohill, who spoke on “Sunlight and Cancer.” Also included were the Science Bowl and Lab Skills Competitions. Clubs represented were from as far away as Ashland and Murray. Of major importance were two $1,000 scholar- ships, awarded for study in the sciences or mathe- matics at Ogden College. The scholarships were made possible through efforts of Dr. Earl Pearson and Dr. Gray Dillard who brought our Outstanding Science Student program to the attention of Mr. Al Temple of the Ogden Foundation, an independent philanthropic organization. The two scholarships were reserved for recipients of the K.J.A.S. Out- standing Science Student program. Final selections were made by the Foundation, assisted by Dr. Dil- lard, based on our list of Outstanding Science Stu- dent awards. These scholarships are often renew- able if the recipients perform up to expectation. It is our hope that we will again have these scholar- ships available and that other foundations will ear- mark some scholarships for similar use. Our regionalization effort has progressed, but not as rapidly as anticipated. Currently, we have a num- ber of individuals who have agreed to serve as board members in the various regions. Murray, Arvin Crafton—Jane Sisk Bowling Green, Mr. Jeff Richardson—C. Mere- dith, Donna Chapin Campbellsville, Dr. Tom Jeffries—Carol Nally, Sister Jane Hancock Covington, Sister Ethel Parrott—Names not sub- mitted as of this date Williamsburg, Dr. Ann Hoffelder—Mary Lane, Charles Phelps, Lawana Scofield Lexington-Richmond, Dr. Truman Stevens—Dr. Don Birdd, Linda Grant, Phil Jones Bullitt-Jefferson County, Mr. Chris Allen—Names not submitted as of this date. As you will note, the regions are being completed and several have said they will be in operation this year. 7. RESOLUTION COMMITTEE. Dr. Paul Frey- tag presented the following resolutions. Resolution No. 1: Whereas, Ashland Oil, a major international oil company which is incorporated in the common- wealth of Kentucky, and Whereas, Ashland Oil has graciously served as the host for the sixty-eighth Annual Meeting of the Ken- tucky Academy of Science, and Whereas, Dr. William Hettinger, Jr., Mr. Tony Ber- ry, Dr. Tom Bean, Mr. William Sutton and many others of Ashland Oil have worked diligently to make this meeting a great success, and Whereas, Ashland Oil has been a leader in many scientific areas, such as synthetic fuel and petrole- um extraction technology, Therefore, be it resolved: that the Kentucky Acad- emy of Science expresses its sincere appreciation to Ashland Oil, and the above individuals, and that the secretary of the Kentucky Academy of Science be instructed to so inform them. A motion was made and seconded from the floor to accept the resolution. Motion was passed. Resolution No. 2: Whereas, admission to Kentucky’s public colleges and universities has traditionally been open to any high school graduate who is a native of Kentucky, and Whereas, The Council of Higher Education in Ken- tucky has been studying the problem of quality of higher education in Kentucky, and Whereas, The Council on Higher Education has concluded that one of the problems in higher edu- cation is that many do not use their opportunities to the fullest that are available to them in high school, and Whereas, the Council has proposed that there be certain minimum high school requirements for un- conditional admission to Kentucky’s public univer- sities, and Whereas, the Council has suggested that each pub- lic college and university set up some provision for the admission, on appropriate and specified condi- tions, of otherwise qualified applicants who do not meet the specified minimum conditions, Be it therefore resolved: That the Kentucky Acad- emy of Science approve, in principle, the efforts of the Council on Higher Education to improve the ACADEMY AFFAIRS scholarship of Kentucky students who plan to enter college. ; A motion was made and seconded from the floor to accept the resolution. Motion was passed. 8. AD HOC COMMITTEES A. Rare and Endangered Species Committee. The report presented by Dr. Branley Branson. The committee respectfully submits the follow- ing revisions, including several changes in status, of the original list of Endangered, Threatened, and Rare animals and plants of Kentucky (Endangered, Threatened, and Rare animals and plants of Ken- tucky, Trans.

Dr. Jerry Baskin and Max Medley are continuing their work on the endangered plants of Kentucky. They will publish a completely revised list in a fu- ture issue of the Transactions. The Lady’s Slipper (see previous page) listed as Cypripedium sp. T. has been officially described by Clyde Reed (Phytologia 48:426-428, 1981) as C. kentuckiense Reed. The species continues to be listed as Threatened. The committee expresses its appreciation to the Kentucky Nature Preserves Commission for its con- tinued cooperation and assistance. B. Committee to Study Legislatively Mandated Educational Programs. Dr. Wallace Dixon made the report. Dr. Dixon said that the committee had nothing significant to report concerning the mandated teaching of scientific creationism. Since its defeat in Lexington the issue of scientific creationism has died down. Dr. Dixon said that the committee would continue to watch this issue and any others that in- volved mandated educational programs. 9. UNFINISHED BUSINESS. There was no unfin- ished business. 82 TRANS. KENTUCKY ACADEMY OF SCIENCE 44(1-2) 10. NEW BUSINESS. A. Dr. Taylor reported that the Academy had been operating at a deficit during the past few years with the deficit being made up from a contribution from the State some years ago. The last year for state contributions was 1979. This grant has carried us through two budget years but will not be available in the future. In order to partly alleviate this prob- lem Dr. Taylor moved that the dues be raised to $15.00. He pointed out that an increase in dues would not totally solve the problem as reflected by the following proposed budget for 1983 which as- sumes the proposed increase in dues.

The following were the main points discussed: (1) Library subscriptions would have to be raised in the near future. (2) An increase in the life membership dues would have to be considered. (3) The possibility of raising page charges was another suggestion. (4) The possibility of separating the Transactions from the dues and give the member the option of receiving the Transactions at a cost over and above the dues. The motion was voted upon and passed effective for the 1983 fiscal year. B. Dr. George made the following proposal for a second area of institutional affiliations. For several years, we have had a class of Insti- tutional Affiliates who have helped support KAS by donations. We have applied a rule of thumb in which we ask each college or university to donate $50 for each 1,000 full-time students. But there does not seem to exist any such rule of thumb for industrial and commerical concerns. At the August meeting of the Board of Directors, it was voted to propose to the membership that there be two areas of Institu- tional Affiliation which would be called (1) Aca- demic Affiliate and (2) Industrial Affiliate. There would be four categories of Industrial Affiliate: Associate Member Member Sustaining Member Patron The cost of each category of membership would be set by the Executive Committee and adjusted from time to time as they saw fit. The costs would be adjusted on a sliding scale with Associate Mem- ber least expensive and increasing in each category. The other area, Academic Affiliates, would operate as we are now doing; we suggest $50 for 1,000 full- time students. Both classes of affiliates would be published annually in the Transactions, in order that they might receive recognition for their contri- butions. Dr. George made a motion to accept the proposal which was seconded from the floor. A suggestion was made, and accepted, to change the Industrial Affiliation to a Commercial and Industrial Affilia- tion. The motion was voted upon and passed. 11. NOMINATING COMMITTEE. Dr. Charles Covell, Jr. offered the following nominations and moved their acceptance. Joe Winstead Robert Creek Morris Taylor Gerrit Kloek Manual Schwartz Vice President Secretary Treasurer Board of Directors Board of Directors The motion was seconded from the floor and passed unanimously, there having been no further nominations.

JOHN R. MACGREGOR, Nongame Wildlife Program, Kentucky Department of Fish and Wildlife Resources, Frankfort, KY 40601. In July 1982 I discovered colonies of Liparis loe- selii (L.) L. C. Rich. (Loesel’s twayblade) and Cor- allorhiza maculata (Raf.) Raf. (spotted coral-root) in Harlan County, Kentucky. There are no previous records for L. loeselii in Kentucky. Earlier reports for C. maculata in Kentucky have been based on robust specimens of the closely-related C. wister- iana or are unsupported by available voucher ma- terial. Photographs of both of these orchids, brief descriptions of the sites in which each was found, and speculations conceming the existence of addi- tional unreported species of orchids in the moun- tains of southeastern Kentucky were presented. Trophic State Analyses and Use Impairment of Selected Public Lakes in Kentucky. TERRY P. AN- DERSON* and L. GILES MILLER. Natural Re- sources and Environmental Protection Cabinet, Di- vision of Water, Frankfort 40601. The Divison of Water surveyed forty-seven pub- licly owned lakes in Kentucky to determine their trophic state. Trophic status was assessed by the Carlson Trophic State Index (TSI). Three lakes were determined to be hypereutrophic, twenty-six were eutrophic, fifteen were mesotrophic and three were oligotrophic. Selected parameter ranges between the hypereutrophic and oligotrophic lakes were, re- spectively: TSI (Chlorophyll), 74-34; maximum chlorophyll-a, 198-3 yg/l; total phosphorus, 840-7 ug/l; conductivity, 512-55 wS/em; euphotic zone depth, 1.2-18.6 m; secchi depth, .3-8.8 m. An impaired use assessment was conducted for eight lakes. Causes of the impairments were attrib- uted to shallow lake basins, excessive nutrient con- tributions from cultural and agricultural sources, acid mine drainage, and hypolimnetic discharges. Vascular plants of Lily Surface Mine Experimen- tal Area, Laurel County, Kentucky. RALPH L. THOMPSON, Department of Biology, Berea Col- lege, Berea, KY 40404. The Lily Surface Mine Experimental Area, a 14.5- hectare abandoned stripmine, was planted with 110 herbaceous and woody species by the U.S. Forest Service in 1965-1966 and then allowed to progress through natural plant succession. Floristic study in 1981-1982 disclosed 341 taxa from 86 families, in- cluding 68 introduced species persisting from the original plantings. Thirty 2 m x 100 m belt tran- sects indicated important trees were Pinus virgin- iana, Liquidambar styraciflua, Acer rubrum, Bet- ula nigra, Cornus florida, Nyssa sylvatica, and Oxydendrum arboreum. Important shrubs and vines were Rhus copallina, Smilax glauca, Rhus radi- cans, Rubus spp., Lonicera japonica, Spireae to- mentosa, and Rosa multiflora. Sixty 1 m xX 1 m quadrats revealed that the Poaceae, Asteraceae, and Fabaceae were the most important families of the herbaceous layer. GEOGRAPHY Visitation patterns of Kentucky resort parks. JOHN L. ANDERSON, Department of Geography, Uni- versity of Louisville, Louisville, KY 40292. Changes in overnight attendance and average distance traveled by visitors from the largest rec- reational markets to Kentucky’s resort parks were examined, revealing an increasing interest in taking advantage of close-to-home opportunities. Recre- ational hinterlands contracted and vistation de- creased for most of the parks during the recent de- cade. Lakes Cumberland and Barkley provided noteworthy exceptions by registering outstanding growth and hinterland expansion. Numerous and complex reasons enter into travel decisions, but em- phasis was given to accessibility, quality of envi- ronments, and state of the economy. GEOLOGY The distribution and volcanic source area for the flint clay parting of the Fire Clay Coal. DONALD R. CHESNUT and ANNE M. SCHREIBER%, Ken- tucky Geological Survey, Lexington, KY 40506. ABSTRACTS OF PAPERS PRESENTED IN 1982 91 To support the volcanic origin for the flint clay parting of the Fire Clay coal bed, an isopach of the parting was constructed. It shows a pronounced de- crease in thickness to the north. Paleogeographic reconstruction of the Middle Pennsylvanian, the isopach of the flint clay parting, the global wind patterns, and the isomass map of the Mt. Saint He- lens ash fall pointed to a source in the south-central Appalachians coinciding with a portion of the Her- eynian magmatic are from Maryland to Georgia. Rare and unique mineral replacement of fossils from the lower and middle parts of the Borden For- mation, northeastern Kentucky. CHARLES E. MA- SON*, Department of Physical Sciences, Morehead State University, Morehead, KY 40351 and JO- SEPH H. GILBERT, Lewis County School System, Vanceburg, KY 41179. The mineralization is restricted to invertebrate fossils found in the Farmers, Nancy, and Cowbell members of the Borden Formation. In lateral ex- tent this mineralization has been observed from Scioto County, Ohio, south to Rockcastle County, Kentucky. The fossils are found in siderite nodules, lenses, and beds preserved as molds and casts with the internal mode dominating. Barite, in a colorless form, is the most common mineral. Other associated minerals in order of decreasing abundance are sphalerite, pyrite, galena, and calcite. Pyrite com- monly replaces areas of original shell whereas the remaining minerals infill voids. Reports of barite and sphalerite replacing or infilling fossils are rare and this report of galena is unique. Pore pressure determination derived from drill data ratios and electric log correlation. H. HULL RUSH, Department of Geology, Austin Peay State University, Clarksville, TN 37040. Data collected from nearby wells can provide in- formation for predicting and determining pressures in oil and gas exploration wells. Data correlation with “E”-long conductivity is often used to predict pressures and dictate drilling fluid weights. A for- mula for determining pressures based on porosity (Boone 1968) is: Pressure, = Pressure, + A Potosi + Mud Weight (ep 2 + MW) When porosity is undetermined, a proposed em- pirical formula based on rate of penetration (ROP) in unrelieved shale sequences is: Porosity, = Porosity, + (AROP x .2) + AMW (0. — 6, + (AROP x .2) + AMW) and: P,=P,+ A@+ MW The results of these formulae are of value since they are independent of surface physical data. Geophysical applications of hypothesis testing and model comparisons of trend surfaces. ALAN D. SMITH, Department of Geology, Eastern Kentucky University, Richmond, KY 40475. The significance of a trend or regression may be tested by performing an analysis of variance, which deals with separation of the total variance of a set of observations into components with defined sources of variation. In the case of trend surface analysis, total variance in an independent variable may be divided into the trend itself, which is de- termined by regression analysis, and the residuals, or error vector. By reducing the sum of squares, which were derived from the least-square criterion, an estimate of variance can be compared by using the F-distribution. Applications of the full and re- stricted models in regression analysis were utilized in determining the highest degree polynomial sur- face for selected geotechnical borehole data, gravity anomalies, oil and gas production, and stratigraphic mapping examples. Regression-analysis techniques applied to petro- graphic studies. ALAN D. SMITH* and GARY L. KUHNHENN, Department of Geology, Eastern Kentucky University, Richmond, KY 40475. Field observations and study of 98 polished slabs and 113 thin sections were used in order to study the depositional environment of the Strodes Creek Member and its relationship to the enclosing Mil- lersburg Member and Tanglewood Limestone Member in north-central Kentucky. The Strodes Creek Member consists of eight microfacies—an al- gal boundstone, a claystone, a dolomitic ostracod packstone, a dolomitic packstone, a dolomitic wackestone, a dolomitic carbonate mudstone, a Tet- radium packstone, and a skeletal grainstone—rep- resenting various sub-environments within a shal- low water, slightly restricted and sheltered depositional framework. Regression-analysis tech- niques and a detailed description of the steps in- volved, including hypothesis testing and stepwise regression, were used to statistically verify the mi- crofacies classification. Initial analysis of mine roof fall data in coal mines of eastern Kentucky. ALAN D. SMITH*, Depart- ment of Geology, Eastern Kentucky University, Richmond, KY 40475 and A. B. SZWILSKI, De- partment of Mining Engineering, University of Kentucky, Lexington, KY 40506. Roof falls are so common a problem that many consider them to be a part of mining operations. The purpose of this study was to develop a survey instrument and resultant pilot study capable of sys- tematically documenting the basic characteristics of roof falls in eastern Kentucky. A statistical study using Pearson correlations, multiple linear regres- sion corrected for multiple comparisons, and fre- quencies was completed for selected variables, e.g., depth, location, span, orientation, pillar dimen- sions, seam and roof fall characteristics, geology of the first four immediate roof beds, water, time, floor heave, roof bolting, and various production param- eters. Although only 13 cases were analyzed in the pilot study, definitive relationships between roof fall, water, and bolting characteristics were established. Discriminative relationships among basic lithol- ogies and engineering parameters obtained from the point load and slake durability tests. RICHARD A. SMATH* and ALAN D. SMITH, Department of Geology, Eastern Kentucky University, Richmond, KY 40475 and JAMES C. COBB, Kentucky Geolog- ical Survey, Lexington, KY 40506. A great need exists for information that allows for the prediction of rock behavior as a function of li- thology. A study to investigate this was based on four cores derived from the eastern Kentucky coal field, sampled at 5-foot intervals for slake durability and point load tests. Twenty-seven research hy- potheses were tested using multiple linear regres- sion, with 15 hypotheses found to be significant at the alpha level of 0.05. Several relationships were established among three basic lithologies of mud- stone, siltstone, and sandstone and their engineer- ing tests for predictive purposes. Geology of Lake Malone and Lake Malone State Park. GAIL S. STAMPER* and JAMES X. COR- GAN, Department of Geology, Austin Peay State University, Clarksville, TN 37040. Massive Caseyville sandstones crop out along the shores of Lake Malone, forming joint-controlled cliffs, locally over 200 feet high. Within cliffs, weathering along joints and along crossbeds has created over 30 small natural bridges, the largest 9 meters in span. Caseyville cliffs also display abun- dant honeycomb weathering. This phenomenon is rarely described from nonmarine, temperate set- tings. Natural bridges and honeycomb make Lake Malone a near classic area for study of differential weathering. The park draws over 400,000 visitors every year, and over 600,000 in good years. Much of its aesthetic appeal is geological in origin. Stratigraphy and petrology of the Laurel Dolo- mite (Silurian) on the western flank of the Cincin- nati Arch, Kentucky. JAMES WEBB* and W. C. MacQUOWN, Department of Geology, University of Kentucky, Lexington, KY 40506. The Laurel Dolomite was deposited on a marine shelf west of an exposed Cincinnati Arch in the II- linois Basin. Five subsurface units consist of sec- ondary dolomite formed by fresh/marine water mix- ing (Dorag model). Structural and stratigraphic hinge-lines separate the shallow shelf from the deeper basin to the west. Petroleum occurs on the shelf in structural, stratigraphic, and unconformity traps. Dominant lithologies consist of two hypidi- otopic early dolomite mosaics: fine crystalline (after micrite) and medium crystalline (after biogenic limestone). Early to late zoned dolomite rhombs and late euhedral poikilotopic dolomite occur in both fine and medium crystalline lithologies. PHYSICS Magnetic dimensional resonance of indium anti- monide at room temperature. RAYMOND EN- ZWEILER* and DONALD MUNNINGHOFF, Department of Physics, Thomas More College, Crestview Hills, KY 41017. TRANS. KENTUCKY ACADEMY OF SCIENCE 44(1-2) We are studying microwave resonances in spheres of indium antimonide. We are particularly con- cemed with magnetic dimensional resonances, from which the carrier concentration can be calculated. We found the magnetic fields at which resonances occur to be about 1,000 gauss higher than that pre- dicted by theory. However, the known carrier con- centration is within the error range of the measured carrier concentration. Thus, we conclude the theory may need slight adjustment but has the potential for providing an effective method of measuring car- rier concentration. PHYSIOLOGY, BIOPHYSICS, AND PHARMACOLOGY Effects of adrenocorticotrophin and danazol on isolated rat adrenal cells by column perfusion. DI- ANE JOHNSON and DAVID MAGRANE*, De- partment of Biological and Environmental Sci- ences, Morehead State University, Morehead, KY 40351. Collagenase isolated rat adrenal cells were sus- pended in columns with Bio-Gel P-2 and perfused with either Krebs ringers (KRBG) or KRBG plus adrenocorticotrophin (ACTH), danazol, or both. Hemocytometer cell counts of viable cells, checked by trypan blue exclusion after isolation, were 364,000/mm® and 303,000/mm® after perfusion, in- dicating only a 16.8% cell loss by continuous per- fusion. Fluorometrically measured corticosterone was stimulated within 5 minutes by 100 wU ACTH (P < .02), and basal release was inhibited by 100 uM danazol within 30 minutes (P < .01). Danazol (100 4M) inhibited 100 ~#U ACTH stimulated cor- ticosteroidogenesis for 20 minutes with simulta- neous perfusion (P < .02), indicating direct inhibi- tion of steroidogenesis. In vitro characterization of danazol binding to specific cytosol receptors. GAIL RUSSELL* and DAVID MAGRANE, Department of Biological and Environmental Science, Morehead State Universi- ty, Morehead, KY 40351. The synthetic steroid danazol was investigated for its dose responsiveness, specificity of binding to cytosol receptors, and ability to translocate cytosol receptors to the nucleus. Receptors for estradiol (E.), dihydrotestosterone (DHT), progesterone (P), and corticosterone (B) were evaluated in uterine, mam- mary, adrenal, and hypothalamic tissues, using the hydroxyapatite assay. Dose responsiveness was shown in increased competition from physiological doses (10-° M) to pharmacological doses (10~° M). At 10-9 M, the androgen receptor (DHT) was bound and translocated most efficiently in all tissues stud- ied, followed by P, E,, and B respectively. These data support the current literature and extend the understanding of danazol’s action to mammary tis- sue in vitro. Effect of running on serum triglyceride and cho- lesterol. MARK SMITH* and RAY HAMMOND, Division of Science, Centre College of Kentucky, Danville, KY 40422. ABSTRACTS OF PAPERS PRESENTED IN 1982 93 Serum levels of several enzymes, triglyceride, and cholesterol in two male runners, age 21 and 38, were substantially influenced by running 7-10 miles. There were age related differences both in pre-run levels and extent of post-run change. Triglyceride decreased 62%, total cholesterol decreased 23%, and high density lipoprotein increased 47% in the older subject (18% and 10% decrease, and 64% increase respectively in the younger subject). These changes persist substantially longer in the older subject. Running appears to keep high density lipoprotein levels in older males at “younger” levels. In vivo study of the effects of danazol on cyto- plasmic receptors in the female rat. DEBBIE SPEN- CER* and DAVID MAGRANE, Department of Bi- ological and Environmental Sciences, Morehead State University, Morehead, KY 40351. Effects of the synthetic steroid antigonadotrophin danazol on cytoplasmic receptors were studied in vivo in adult female rats. Competition with estrogen (E,), progesterone, dihydrotestosterone, and corti- costerone receptors in uterine, mammarian, adre- nal, hypothalamic, and ovarian tissues were evalu- ated by hydroxyapatite micromethod. Long term, low dose (4 mg/kg/14 days) of danazol resulted in significant reduction of E, receptors (P < .05) anda non-significant reduction of other receptors in both intact and ovariectomized rats. Uterine, adrenal, and ovarian weights were significantly reduced by dan- azol injections (P < .02). Short term, high dose (8 mg/kg/3 days) demonstrated no reduction of organ weights and showed a non-significant reduction of all receptors. PSYCHOLOGY Inferential statistical techniques commonly em- ployed in comtemporary life science journals. FRANCIS H. OSBORNE, JEANNE S. OSBORNE, KATHERINE E. KOCH*, and MALCOLM P. GRAHAM, Morehead State University, Morehead, KY 40351. The purpose of this study was to determine the incidence and type of inferential statistics em- ployed in several disciplines and to use this infor- mation to make recommendations for content in an interdisciplinary statistics course. Seven psycholo- gy journals were surveyed for frequency of occur- rence of statistical procedures in 1981. APA journals included were those examined in Edington’s (1964, 1974) tabulations. Three journals were selected on the basis of “impact factor” in each of three addi- tional fields frequently served by introductory sta- tistics courses: biology, education, and sociology. Contingency table analysis indicated substantial overlap in statistical techniques employed in these disciplines as well as differences in emphasis spe- cific to disciplines. For example, over 70% of psy- chology articles surveyed used analysis of variance techniques. The other disciplines surveyed tended to use multiple regression techniques substantially more than did psychology. SCIENCE EDUCATION Arson investigations in the laboratory: classroom applications. ROBERT E. FRAAS, Forensic Sci- ence Program, Eastern Kentucky University, Rich- mond, KY 40475. In response to increased emphasis on arson de- tection, a special topics course on arson evidence analysis has been developed. Topics included the chemistry and physics of fire, heats of combustion, petroleum refining processes, methods of analysis, and report writing/courtroom testimony. Several different extraction procedures were used in anal- ysis of unknown arson residue samples. Laboratory experiments also included gas chromatographic analysis of common accelerants, analysis of dye ad- ditives by thin layer chromatography, and analysis of lead additives by gas chromatography/mass spec- trometry. Stated reasons for withdrawal and degrees of satis- faction among college persisters and nonpersist- ers. ALAN D. SMITH, Department of Geology, Eastern Kentucky University, Richmond, KY 40475. Revised questionnaire forms by the National Center for Higher Education Management Systems were given to students enrolled in the Community and Technical College and the General College in academic year 1978-1979 at The University of Ak- ron. The response rate of usable questionnaires var- ied from 22% of nonreturning students (485) to 28% of the continuing student population (2,995). Dis- criminative analysis of demographic variables was completed to assess selection bias. Conflict with job and studies, not enough money for school, and needed temporary break from school were reasons for withdrawal cited by more than 20% of the stu- dent nonpersisters. Nonpersisters listed counseling and advising services, financial aid opportunities, and quality of instruction more frequently as the first factors to be changed. Persisters listed registra- tion processing, parking availability, and television courses as the more frequent items to be changed. ZOOLOGY AND ENTOMOLOGY Distribution of two treehole mosquitoes, Aedes triseriatus Say and A. hendersoni Cockerelle (Dip- tera: Culicidae) in Berea, Kentucky. JEROME H. WALLER, Department of Biology, Berea College, Berea, KY 40404, and ELLEN M. BALLARD*, De- partment of Entomology, University of Kentucky, Lexington, KY 40506. Four line transects and three area plots were used to determine the occurrence of Aedes triseriatus Say and A. hendersoni Cockerelle in the Berea Col- lege Forest in Madison County, Kentucky. Effects of altitude, tree species, sampling date, and climatic conditions were examined. Sampling was conduct- ed with the use of ovitraps, and two additional mos- quito species were also found: Anopheles barberi and Toxorhynchites sp. The protozoan parasite As- cogregarina barretii was identified in field-collect- ed larvae of Aedes triseriatus but not in A. hender- soni. In late summer sampling, the effect of transmittance of light in water from the traps was compared with number of eggs collected. Trans. Ky. Acad.

MORGAN Department of Geology, Eastern Kentucky University, Richmond, Kentucky 40475 ABSTRACT Since 1918, approximately 1,100 oil and gas wells have been drilled into the Berea Sandstone of Lawrence County, Kentucky. Information from 354 of these wells was used in a statistical search for factors influencing hydrocarbon occurrence. Variables studied are elevation of the top of the Berea Sandstone, Sunbury Shale thickness, oil production, gas production, Berea thickness and five lithologic characteristics. Of the 2 general and 18 specific hypotheses tested, only 2 were found significant. Elevation of the Berea accounted for 4.9 per cent of the common variance in oil production and 8.9 per cent of the common variance in gas production. Unstudied factors account for the majority of the variance in hydrocarbon occurrence. INTRODUCTION The first well to penetrate oil bearing sediments in Kentucky was drilled in 1819. Since that time, over 200,000 oil and/or gas wells have been drilled (1, 2, 3). One of the most important producing formations in the state is the early Mis- sissippian Berea Sandstone. This forma- tion extends from its type locality in northern Ohio into eastern Kentucky and western West Virginia. In general, the Berea in Kentucky is composed of light to medium gray sandstones, siltstones, and shales. The underlying Bedford for- mation is so similar that many research- ers find it difficult to separate the 2 units (4, 5, 6, 7, 8, 9). Since the turn of the century, Law- rence County, Kentucky (Fig. 1), has been in the forefront of Berea-oriented oil and gas exploration, with approximately 1,100 wells drilled. Almost 17 million barrels of oil have been produced since 1918 (1) and 23 hydrearbon pools are recognized 95 (Fig. 2). The first 2 pools were discovered in 1912: the Fallsburg Pool, producing from the Berea Sandstone and Ohio Shale, and the Busseyville Pool, producing from the Berea and Clinton Sandstones. The Redbush Pool, discovered in 1912, has the largest number of producing formations; 8 including the Berea (1, 3). In 1978, two new Berea pools were discovered: Webbville South and Jobe Branch (Nut- tall, Kentucky Geol. Survey, Lexington, Kentucky, personal communication). The purpose of this paper is to examine within Lawrence County, factors that are thought to be associated with hydrocar- bon occurrences in the Berea Sandstone. METHOD The Kentucky Department of Mines and Minerals supplies the Kentucky Geo- logical Survey with location plots for all oil and gas wells that are permitted with- in the state. Upon completion of the well, the operator is required to supply the 96 LAWRENCE COUNTY Fic. 1. Kentucky Geological Survey with copies of the drillers’ log and geophysical logs, if any. This material is stored in Lexing- ton at the Geological Survey and is open for public inspection. An inventory was made of every well on file at the Geological Survey that pen- etrated the Berea Sandstone in Lawrence County. Each well was given an identi- fication number and plotted on the ap- propriate seven and one-half minute to- pographic map. As each well was plotted, a list of all the pertinent data contained in the well envelope was compiled. The operator, farm name, Carter Coordinate location, quadrangle, date drilled, eleva- tion, and total depth were recorded. The production status of the well was listed, and if there was production, the amount of production, producing formation, and producing interval were also noted. The type and quality of geophysical logs, if any, were listed as was the availability of well cuttings. Depths to the top and bot- tom of the Sunbury Shale and Berea Sandstone were also recorded (Fig. 3). Cuttings were studied using a binocu- lar microscope. The per cent of sand present in each sample was calculated TRANS. KENTUCKY ACADEMY OF SCIENCE 44(3-4) Location of the study area. using charts published by Compton (10). Siltstone was grouped with shale be- cause their gamma ray curves are similar (11) and because neither is favorable for petroleum accumulation. In an attempt to gain more stratigraphic control, the Berea was divided, vertically, into 20-foot in- tervals. Per cent sand was averaged for each interval and will be referred as sand Fic. 2.

Data developed were analyzed using multiple linear regression, a long-used approach to statistical evaluation that is related to the analysis of variance tech- niques which analyses estimate popula- tion variance and yield an F-statistic (12). By allowing the selected predictor vari- ables to enter into a multiple regression equation with either gas or oil production as the criterion, R? values were obtained. An R? value in linear regression is the amount or per cent of the variance in the criterion variable which is accounted for the predictor variables; another term de- scribing this is common variance. The R? value indicates to what extent the select- ed variables are predictable of the ob- served variance in oil and gas production. If one subtracts the amount of common variance from both the full and restricted models, a figure for the per cent of the common variance can be found for the predictor variables not covaried or ac- counted for in the model. Variables used in the study are elevation of the top of the Berea Sandstone, Sunbury Shale thickness, oil production, gas production, Berea thickness, and sand per cent cut- tings number 1-5. For purpose of this study, the entire lithologic interval be- 19) Fic. 5. Elevation contour of the top of the Berea Sandstone. (Contour interval = 100 feet.) tween the Ohio and Sunbury Shale was considered to be the Berea Sandstone. This removed uncertainty about recog- nition of the Bedford Shale. In order to test for significant relation- ships among these variables, a series of hypotheses were developed. The .05 level of significance was considered sufficient to reject the nondirectional two-tailed hy- potheses. When appropriate, a modifica- tion for multiple comparisons was made (13). Hypotheses tested are: G,: Do the variables Elevation of the Top of the Berea Sandstone, Sunbury Shale Thickness, Gas Production, Berea Thickness, and Sand Per Cent Cuttings 1-5 account for a signifi- cant amount of variance in predict- ing Oil Production? H,: Does the variable Elevation of the Top of the Berea Sandstone account for a significant amount of variance in predicting Oil Production?

An F-test was utilized to test for significant relationships between oil and gas production and various parameters associated with the Berea Sandstone. The assigned alpha level of .05 for a two-tailed, nondirectional test was considered statistically significant. However, the employment of a correction for multiple comparisons was necessary, using the Newman and Fry (13) method. The corrected alpha level of .006 was used before the research hypothesis was considered significant. * This statistic is not valid, due to the large number of missing cases.

RESULTS Data from 354 wells, which penetrate the Berea Sandstone, were analyzed. Well locations are shown in Fig. 4. Of these wells, 57 were dry holes, 46 were oil wells, 98 were gas wells, 8 were oil and gas wells, 32 were wells with oil shows, 26 were wells with gas shows, 27 were wells with oil shows and gas shows, 6 were oil wells with gas shows, 28 were gas wells with oil shows, and 26 were un- classified.

The R, term in Table 1 indicates the extent to which a variable is predic- tive of the observed variance in oil and gas production. The maximum value of R? = 1.0 for continuous values. Of the sig- nificant relationships found, the highest R2 was 8.88 per cent and the lowest was 4.89 per cent. Thus, the other 91-95 per cent of the variance in gas and oil production is unaccounted for, even though the hypotheses were significant. Table 2 represents the significant corre- lation coefficients of the variables stud- ied. The ability of the test to detect a dif ference when it does exist for a medium- effect size was over 95 per cent. Since some of the independent variables have correlations significantly greater than zero, care must be taken when interpret- ing the regression weights, due to mul- ticolinearity. Table 3 summarizes the de- scriptive statistics for both the criteria and predictor variables. CONCLUSIONS Data may be biased as a result of geo- logical exploration programs designed to enhance oil and gas discovery. In addi- tion, because of the age of many of the wells, since operators are not required by the state to provide production statistics, data acquired for some of the variables may be poor. However, the F-test is a very robust statistical technique and is rela- tively insensitive to violations of random selection and normality of distributions. Testing of the 2 general and 18 specific hypothese yielded only 2 hypotheses that are significant. Elevation of the top of the Berea Sandstone was significant (P = .0001) in predicting oil production, but it only accounted for 4.89 per cent of the variance in oil production. In addition, this variable was significant (P = .0000) in predicting gas production, accounting for 8.88 per cent of the common variance in gas production. Many of the correlation values were significant, suggesting that a wide range of geological conditions may explain these results since only a small amount of vari- ance in oil and gas production was ex- plained by the two significant hypothe- ses. Other factors clearly account for the majority of the variance in hydrocarbon occurrence. A greater understanding of the geology of eastern Kentucky and of the Berea 102 Sandstone is needed to help understand factors associated with hydrocarbon oc- currence. The refinement of relation- ships among the different structural ele- ments of the region is greatly needed. Analysis of the Berea-Bedford interval with emphasis on the Berea-Bedford boundary and the sources of their clastics merits study. Further analysis of hydro- carbon occurrences in the Berea Sand- stone using oriented cores, if they be- come available, would be useful in delineating the effects of fracturing, mica content and orientation, variations in ce- mentation, and many other variables that may be important.

Notes on the coloration and pigment distribution in these two undescribed species are included. INTRODUCTION It has been known since the 1960’s that the Cumberland River drainage below the falls and portions of the Tennessee River drainage contain two undescribed cypri- nid fish species, the putative palezone and sawfin shiners (1), in Kentucky principal- ly in the Little South Fork of the Cum- berland River (2, 3). The palezone shiner, Notropis sp. cf. procne is being consid- ered by Robert E. Jenkins, Roanoke Col- lege, Virginia, and the sawfin shiner, No- tropis sp. cf. spectrunculus, is being studied by John S. Ramsey, Auburn Uni- versity (4). Both species are of consider- able environmental concern (5), and very little is known about the biology, vari- ability, or total geographic distribution of either species. This contribution presents information on the variability of several proportional measurements and counts in these two species of minnows in Kentucky. OBSERVATIONS Both species of minnows are still rela- tively abundant in the high-quality waters of the Little South Fork of the Cumber- land River in Kentucky, where the sawfin shiner ranks seventh and the palezone shiner second in relative abundance be- hind Notropis telescopus (3). Warren (6) recently reported sawfin shiners from Rock Creek (Big South Fork of the Cum- berland River) in McCreary County, and from Pitman Creek, a Cumberland River tributary in Pulaski County, but the pa- leozone shiner seems to be restricted to the Little South Fork within the Cum- berland drainage. Because most field biologists and ich- thyologists are not familiar with these species, the following general descrip- tions are presented. The palezone shiner (Fig. la) is a slen- der, slab-sided minnow with (in life) nearly transparent flesh and a complete lateral line. Proportional measurements and counts are presented in Tables 1-3. The color pattern is somewhat reminis- cent of that in the swallowtail shiner. Large melanophores line the upper lip and there are a few scattered ones on the lower lip; otherwise, the venter of the head and most of the belly are nearly immaculate. There is a very narrow black streak on the venter behind the anal fin and a very black streak occurs along the base of that fin. A narrow, dusky band suf- fused by silver (in life) follows the lateral line and a black triangle (apex forward) is associated with each lateral-line pore. The sides below and immediately above the lateral line are essentially pigment- less. Above the pale zone, the scales are outlined with small melanophores. A small black blotch occurs just in front of the dorsal fin and there is a second blotch on the back near the middle of the dorsal fin. A dusky streak extends through the eye, and the uppermost and lowermost rays of the caudal fin are streaked with black. By contrast, the sawfin shiner (Fig. 1b), presumed to be most closely related to the mirror shiner (3, 4), is not so distinc- 103 104 TRANS. KENTUCKY ACADEMY OF SCIENCE 44(3-4) Fic. la.

The lat- eral line is complete, the anteriormost scales being somewhat higher than wide. The supratemporal lateral-line canal is narrowly to widely interrupted and the infraorbital canal is narrowly interrupted in a few specimens. Proportional mea- surements and counts are presented in Tables 1-3. In coloration, the sawfin shiner resem- bles the mimic shiner. Each pectoral fin ray, but not those of the pelvics, bears a row of very fine melanophores. There is an indistinct black blotch at the base of the caudal fin from which streaks extend out onto the membranes. A distinct black spot occurs on the belly immediately in front of the anal fin and there is a dark midventral streak behind that fin. A black streak is obvious on the back in the base of the dorsal fin. In life, the general coloration is silvery. The scales above the complete lateral line are outlined with melanophores and the sides below the midline, the belly be- hind the pelvic and anal fins, and the sides of the caudal peduncle bear scattered and indistinct brownish freckles. The upper lip is lined with enlarged melanophores. A dusky band suffused with silver ex- tends from head to tail, becoming slightly enlarged at the base of the caudal pedun- A with any other species in Kentucky. The pigmentless, virtually transparent stripe above the lateral line is diagnostic. The only other minnow in Kentucky waters having a similar trait is the Tennessee shiner, Notropis leuciodus, which is sep- arable by other features. By contrast, the sawfin shiner may be easily confused with Notropis volucellus, the mimic shiner. However, the last-named species has all the rays of the dorsal fin lined with me- lanophores whereas in the sawfin shiner only the first four rays are marked in that manner. Both species, and their closest relatives, have the pharyngeal teeth ar- ranged in a single row (4-4).

BONNEY Department of Forestry, University of Kentucky, Lexington, Kentucky 40546-0073 ABSTRACT A questionnaire was mailed to 120 county extension agents in February 1981. The question- naire was used to identify their needs for information on various fish and wildlife topics, to estimate the number of requests they received for fish and wildlife information, and to determine the best means of information dissemination. The 80 respondents indicated they most needed aquaculture information for warm-water species; animal damage control information for black- birds, moles, woodchucks, pigeons, house sparrows, and rodents; and habitat management in- formation on bobwhite quail, white-tailed deer, cottontail rabbits, and squirrels. This information could best be provided through publications, workshops, and 4-H projects. INTRODUCTION County agricultural extension agents are employed through the Cooperative Extension Service (CES) stationed at Land Grant Universities in each state. The CES involves cooperation among federal (USDA), state (university), coun- ty, and private people and funds (1). County extension agents are responsible for providing fish and wildlife informa- tion to the public via 4-H, workshops, phone conversations, and on-site visits. Wildlife and fisheries extension special- ists work with the county agents to pro- vide a variety of educational programs (publications, workshops, 4-H projects, and demonstrations) but identification of the everyday information needs of county agents is essential before a prioritized list 1 The information reported in this article (82-8- 251) is in connection with Agricultural Experiment Station Project No. 624 and is published with the approval of the Director. of goals can be developed by personnel providing information to the public via county extension agents. Identification needs also may provide wildlife profes- sionals with an indication of the public’s views on fish and wildlife importance, particularly for those residing in rural vs urban environments. The objectives of this study were to identify the important fish and wildlife information needs of county extension agents in Kentucky, and to compare in- formation needs among 3 levels of human population density and among 4 geo- graphic areas. METHODS A questionnaire was developed which addressed 4 broad topical areas: (1) the absolute and proportional number of re- quests made of a county agent for fish and wildlife information in 1980, (2) ranking of 13 broad categories of fish and wildlife topics based on the number of requests received in 1980 for each topic, (3) iden- WILDLIFE INFORMATION NEEDS IN KENTUCKY—McComb and Bonney tification of desirable information trans- fer techniques (field days, publications, etc.), and (4) determination of the degree of interaction with conservation officers and wildlife biologists of the Department of Fish and Wildlife Resources during 1980. Within 5 of the 13 broad categories of fish and wildlife topics, a list of 8 to 11 wildlife or fish taxa were listed and ranked based on number of requests received for each taxa within that wildlife topic. Questionnaires were mailed during Feb- ruary 1981 to the county agent for agri- culture in each of the 120 counties in Kentucky. Geographic and demographic strata were developed at the county level to identify differences in responses among eastern, central, Bluegrass, and Purchase physiographic regions in Kentucky and among high (>20 people/km?), medium (<20 people/km?, =10 people/km?), and low (<10 people/km?) human population densities (Fig. 1). Mean number of re- quests, mean contacts, and mean ranks were compared among geographic and demographic strata using an analysis of variance with Duncan’s multiple range test. RESULTS Eighty of 120 county agents responded to the questionnaire. Respondents were uniformly located across the state (Fig. 1). Information Requests.—Respondents re- ceived an average of 65 requests for wild- life information and 35 requests for fish information, but the requests per county agent varied widely (SD = 231; 89.8, re- spectively) (Table 1). This represented 1.8% and 0.9% of the total requests each year. The number of wildlife and fish infor- mation requests did not vary geographi- cally (P > 0.05) but did vary demograph- ically. An average of 4.0% of all urban contacts dealt with wildlife, while 1.3% and 0.7% were wildlife oriented in me- dium- and low-population areas, respec- tively. Similarly there was a larger pro- portion of fish-oriented contacts in high population areas than in medium- and low- population areas. There are a greater 107 as Central Purchase Fic. 1.

Total agent contacts concerning all types of agricultural information were higher in central Kentucky (x = 5,148) than in eastern Kentucky (¥ = 1,600) (P < 0.05). Important Fish and Wildlife Topics.— Management of fish ponds and animal damage control (ADC, including control of undesirable species) had the lowest mean ranks (highest priority) of 13 fish and wildlife topics (Table 2). This trend was consistent over population and geo- graphic strata. Game management infor- mation was more important in eastern Kentucky (, = 3.6) than in the Bluegrass Area (¥p = 6.0) (P < 0.05). Information on management of nongame species was more important in urban (Xp = 6.1) than rural (Xp = 9.0) areas (P < 0.05). Infor- mation on hunting, fishing, trapping, wildlife diseases, and wildlife food con- sistently received low priority. Important Fish and Wildlife Taxa.—Fish species for which high information prior- ity was given were warm-water species that may be found in farm ponds: large- mouth bass (Micropterus salmoides), cat- fish (I[ctalurus sp.), and crappie (Pomoxis spp.). Cold-water species (trout (Salmo spp.), smallmouth bass (Micropterus do- lomieui), and rock bass (Ambloplites ru- pestris)) and bluegill (Lepomis macro- chirus) received lower priority.

Mean ranks for importance of aquatic taxa did not differ among de- mographic or geographic strata. Information on control of blackbirds (Icteridae) and moles (Scalopus aquati- cus and Parascalops breweri) received the highest priority among pest species. Con- trol of woodchucks (Marmota monax), pi- geons (Columba livia), house sparrows (Passer domesticus), rats, and mice also received high priority. Rat and mouse control was more important in mid-pop- ulation areas than in urban or rural areas (P < 0.05). Fewer requests were made for woodchuck control information in the Purchase Area than elsewhere (P < 0.05), possibly because they are less numerous in the Purchase Area than in the rest of the state (4). Information on control of pi- geons and house sparrows was more im- portant in the Purchase Area than in the rest of the state. Information requests for other taxa—snakes (Colubridae), squir- rels (Sciuridae), bats (Vespertilionidae), woodpeckers (Picidae), chipmunks (Tamias striatus), beavers (Castor cana- densis) and raccoons (Procyon lotor)— were low and consistent over geographic and demographic strata. Management information for bobwhite quail (Colinus virginianus), white-tailed deer (Odocoileus virginianus), cottontail rabbits (Sylvilagus floridanus), and squirrels received the highest priority among game animals. Rabbit manage- ment information was more important in urban and mid-population areas than in rural areas (P < 0.05). Information on mourning dove (Zenaidura macroura) management was important in central and eastern Kentucky. Management informa- tion for raccoons, foxes (Vulpes vulpes and Urocyon cinereoargenteus), ducks, geese, wild turkeys (Meleagris gallopavo), and woodcocks (Philohela minor) received low priority and was consistent over geo- graphic and demographic strata. Information needs on nongame man- agement, particularly desirable in urban areas, focused on snakes, bats, small mammals, songbirds, and raptors. The importance of snake information was higher (P < 0.005) in urban and mid-pop- ulation areas than rural areas.

Respondents ranked foxes, muskrats (Ondatra zibethicus), raccoons, and minks (Mustela vison) the important furbearers for which information is needed. Infor- mation needs for opossums (Didelphis virginianus), skunks (Mephitis mephitis and Spilogale putorius), and beavers were consistently low. Information Transfer Techniques.—Over 60% of the respondents indicated that an extension newsletter from the University of Kentucky would be a desirable method of informing them and the public on fish, wildlife, and forestry topics (Table 1). Short courses and 4-H programs were also considered important methods. Devel- opment of clubs or leases was not consid- ered a desirable means of informing the public about fish and wildlife (Table 1). DISCUSSION Several state and federal agencies are at least in part responsible for providing fish and wildlife information needs to the public. In addition to the Cooperative Extension Service, the Soil Conservation Service, U.S. Fish and Wildlife Service, and the Kentucky Department of Fish and Wildlife Resources provide written infor- mation and consultation with the public regarding fish and wildlife information. Our results may be biased toward infor- mation needs associated with agricultural situations because county agents most frequently have training in agriculture, but we think that our results provide prioritized guidelines for preparation of written materials and short courses to best meet the needs of the public. Of highest priority is aquaculture in- formation for warm-water fish produc- tion. County agents and landowners must rely on aquaculture advice from the De- partment of Fish and Wildlife Resources and from federal agencies since there is currently no designated aquaculture spe- cialist in the Kentucky CES. An aquacul- ture program is being developed at Ken- tucky State University to meet this need. It is imperative that these agencies co- operate among themselves and especial- ly with CES personnel if we are to pro- vide this information. Animal damage control has long been recognized as an important information need of the public (5, 6). In Kentucky, information on blackbird control is need- ed and since the U.S. Fish and Wildlife Service is currently conducting research on blackbird control in this state, we en- 110 courage their cooperation with county agents in disseminating the most current techniques for blackbird control. Infor- mation on control of other species such as moles, woodchucks, pigeons, house sparrows, and rodents is also needed. A handbook on Prevention and Control of Wildlife Damage is available (7), but it is not specific to Kentucky. A handbook of animal damage control in Kentucky, based on information from a variety of sources, was prepared (8), but additional infor- mation must be supplied to county agents as new techniques become available. Fi- nally, short courses and workshops on ADC, similar to those currently conduct- ed by the Fish and Wildlife Service, should be scheduled on a regular basis throughout the state and with inter-agen- cy coordination. Information on management of quail, deer, rabbits, and squirrels is widely available (9, 10), but little information is specific to Kentucky. Publications deal- ing with these topics as they apply to Kentucky, in combination with work- shops or field days are needed to make landowners, especially farmland owners, aware of the benefits of maintaining a di- versity of habitats for these species. Nongame management techniques for reptiles, birds, and mammals should be made available to the public, particularly in urban areas. As urban areas expand, the need for this information will likely increase (11). Projects through the 4-H system would greatly enhance educational efforts in habitat management for non- game and game species. New and updat- ed projects are needed similar to those developed by the Kentucky Nature Pre- serves Commission (12). A coordinated effort among agencies is essential if we TRANS. KENTUCKY ACADEMY OF SCIENCE 44(3-4) are to maximize our educational efforts in fish and wildlife.

BRANSON, AND DONALD L. BATCH Department of Biological Sciences, Eastern Kentucky University, Richmond, Kentucky 40475 ABSTRACT This article demonstrates some of the capabilities of a computerized information/retrieval system designed to store distribution and ecological data of the lotic organisms of Kentucky. Data for 152 species of fishes correlated with stream-order occurrence in the Upper Kentucky and Upper Cumberland river systems are presented. INTRODUCTION Numerous reports on the fishes of the Upper Cumberland and Upper Kentucky rivers have been published. In an at- tempt to more fully understand the dis- tribution and ecological affinities of the Kentucky aquatic fauna and flora, we (1) developed, in conjunction with the Ken- tucky Department of Natural Resources and Environmental Protection, a com- puterized information/retrieval system for all the lotic organisms reported in the lit- erature with indications of habitat, stream order, water chemistry, and other ecolog- ical notations, including river drainage, subdrainage, and physiographic region. Although this system doubtless will re- quire constant revision, purging of errors, and periodic updating as new srattomanee tion is published, this open-ended sys- tem is a very facile one that allows the retrieval of data in a variety of forms and correlations. The data presented here (correlations between fish species and stream magnitude in the Upper Cumber- land and Upper Kentucky river basins) are but one example of the system’s ca- pability. Many others are possible, i.e., correlations between species and types of habitat, between species and water chemistry, between species and physio- graphic regions, and so forth.

The Upper Cumberland River arises in the highlands of SE Kentucky, draining an area of approximately 18,195 km? (Fig. 1). The main stream is formed at the junction of Poor Fork, Clover Fork, and Martin’s Fork in Harlan County, flowing in a gen- eral westward course through a gap in Pine Mountain before reaching Cumber- land Falls (3). Among its principal tribu- taries are the Big South Fork, the Laurel, and Rockcastle rivers in SE Kentucky. The topography of the Upper Cumber- land River basin is quite variable as the stream passes through several distinct physiographic regions. The easternmost portion of the watershed is mountainous with relief and elevation increasing to- ward the headwaters. Eastern portions of Laurel and Jackson counties, central Knox and Whitley counties and southcentral McCreary County lie in the Plateau Area which is the least rugged portion of the drainage. That portion of the drainage is characterized by undulating to rolling terrain. To the immediate west lies a nar- row band known as the Escarpment Area that encompasses much of the Rockcastle and Big South Fork rivers and Cumber- land Falls. The topography is rugged with steep-sided and clifty valleys and narrow ridges. The westernmost portion of the Upper Cumberland River drainage lies in the Mississippina Plateau, an area that is variable with some rolling and undulat- ing terrain. In places it is hilly or karsted, and stream drainages may be rough and precipitous (3).

The prin- cipal tributaries are the North, Middle and South forks, the Red River, the Dix River, and Elkhorn and Eagle creeks. The basin comprises 17,975 km?, much of it in rel- atively fertile limestone land (2). Portions of the headwaters are severely polluted by acid-mine drainage, coal-mine wastes, and by heavy siltation. RESULTS Utilizing information from the retrieval system developed by us, we obtained distributional data for 152 species of fish- es reported from the Upper Cumberland and Upper Kentucky river basins, corre- lated by stream order and drainage basin. Of the total, 40 species occurred in the Upper Kentucky River exclusive of the Upper Cumberland, and 20 species oc- curred in the Upper Cumberland exclu- sive of the Kentucky River. The remain- ing 92 species were shared by the two drainages. The distributional data re- trieved from the storage system are pre- sented in Table 1. This system allows investigators to eas- ily discern various distributional pat- terns, such as stream-order restrictions, as exemplified by Hiodon alosoides, H. ter- 116 gisus and Hybopsis insignis (5th order or higher), rarity and/or disjunction, as in Hybognathus nuchalis and Lepomis gib- bosus, and drainage restrictions, as in No- comis biguttatus. This article, of course, is merely an ex- ample of the system’s capabilities. Many other combinations are possible. Inter- ested investigators may contact Dean Donald L. Batch, Eastern Kentucky Uni- versity, for additional information.

ABEL AND RUDOLPH PRINS Department of Biology, Western Kentucky University, Bowling Green, Kentucky 42101 ABSTRACT A study of the spatial distribution and temporal occurrence and diversity of rotifers in relation to certain chemicophysical parameters was conducted in Barren River Reservoir, Kentucky, a monomictic flood control lake in southcentral Kentucky, from January, 1970, through January, 1971. Average rotifer densities, in the main pool and tailwater, ranged from 2 to 565/]. From July through September densities of rotifers at 6 m were significantly different from those at all other depths except 3 m (3 m was not significant from the remaining depths). A diel study in July revealed that this vertical pattern persisted over a 24-hour period. During other months (also shown in diel studies of April and January) rotifers were generally more uniformly distributed at all depths. Species diversity per sampling date was greatest from June through mid-October (12 species). This period was characterized by low reservoir discharge (50 cfs), decreased tur- bidity, increased Secchi disc transparencies (a mean of 3 m), and increased water temperatures and stratification. A total of 28 species referrable to 18 genera of rotifers was identified during the study. Polyarthra spp. (3), Keratella spp. (5), and Conochilus unicornis were the dominant rotifers; they comprised 75-85% of the population when present. Keratella cochlearis, Polyarthra vulgaris, and Kellicottia bostoniensis were most persistent and characteristic of the lake. Ke- ratella americana, Ploesoma sp., Hexarthra mira, Keratella crassa, and Brachionus angularis were warm water forms. Keratella quadrata, Kellicottia bostoniensis, and Polyarthra minor were cold-water forms. INTRODUCTION This study was undertaken to deter- mine the spatial and temporal distribu- tions and diversity of rotifers in Barren River Reservoir in southcentral Kentucky and, where possible, to relate these find- ings to chemicophysical features charac- teristic of the reservoir. The study was conducted from January, 1970, through January, 1971, in the main pool area of the lake. Description of Study Area Barren River Reservoir (Table 1), a monomictic lake, is an integral unit of the comprehensive flood control plan for the Ohio and Mississippi Rivers enacted in 1938. Impounded in 1964, it is located in Allen, Barren, and Monroe counties, Kentucky; approximately 20 miles north of the Kentucky-Tennessee boundary. Barren River Reservoir has a capacity for multilevel discharge with discharge ports at 161, 155, and 145 m mean sea level. During the study period, water was drawn from the various levels of the lake from January to April. From April through September, pool elevations of 171 m msl were maintained by the Corps of Engi- neers by regulating discharge which orig- inated from the upper 3 m of the main pool. A conical extension with its apera- ture positioned upward was affixed to the tower around the port at 161 m msl to allow withdrawal at the 3 m level. This summer discharge regime was main- tained as part of a more comprehensive program concerned with overall produc- tivity of the reservoir (1). After 30 Sep- tember, rapid drawdown was initiated to achieve a winter pool level of 161 m msl by December; the drawdown regime af- ter 30 September was similar to that of January to April. Thus, the level of the main pool varied 25 m to 15 m annually due to the discharge regime employed, fluctuations in discharge sometimes re- flecting the need to maintain a given pool level (Fig. 1).

Tailwater samples were collected with the use of an automatic plankton sampler (2) located in the tailwater area. Samples of 114 liters were filtered through the net and bucket of the Birge-Juday sampler. All samples were preserved in 10% for- malin. Enumeration was accomplished using a Sedgewick-Rafter counting cell. Chemicophysical Measurements and Determinations Dissolved oxygen, temperature, dis- solved solids, and pH were determined from water samples collected with a 2- liter Kemmerer sampler. From 26 Janu- ary through 10 April dissolved oxygen and temperature were measured with a Yel- low Springs Instrument 51A oxygen me- ter and probe; thereafter, dissolved oxy- gen was measured with Hach Chemical Co. methods and reagents. Dissolved sol- ids were measured with the Myron L DS meter. The pH was determined with a Sargent-Welch, Model PBL, pH meter within 10 hours after the water samples were returned to the laboratory. Secchi disc transparencies were determined in situ. Mean values were calculated from samples at depths. Daily discharge data were obtained from the Corps of Engi- neers, Louisville, Kentucky. RESULTS General Chemicophysical Features The general temperature and dissolved oxygen distributions in the reservoir dur- ing the study period were typical of tem- perature zone lakes (Figs. 2, 3). Stratifi- cation began in late April, was completed by August, and fall circulation occurred in late October. The maximum tempera- ture (30°C) at the surface was on 1 Au- gust, the lowest (3.1°C) was on 26 Janu- ary; the metalimnion was 6-9 m from June to mid-October. There was a trace amount of oxygen in the hypolimnion throughout the summer and the average pH was con- sistently slightly alkaline.

Analyses of variance (3) were conduct- ed on the vertical distributions for spring (March—June), summer (June—Septem- ber), autumn (September—December), and winter (December—March). These analyses showed that the only significant difference between depths occurred dur- ing summer. With the use of Duncan’s new multiple range test (3), it was found that total rotifers at 6 m and 3 m were not significantly different, but that densities at 6 m were significantly greater than those at all other depths. Species richness was greatest during periods of maximum stability (mid-June through mid-October) (Fig. 7). An aver- age of 12 species was found during these months (the maximum was 16 species on 15 August and the minimum was 9 species on 20 June), whereas, the average for all other months was six. Rotifer densities in the main pool and those in the tailwater did not always cor- respond (Fig. 5). For example, on 24 April, (water was discharged from the upper 3 m beginning | April) 545/1 were found in the tailwater, and only 54/] were found in the main pool. The average number of animals at the surface and 3 m was 134/] which was 83% of the total rotifers pres- ent in the water column. In the main pool on 18 July most rotifers were present at 6 m (483/1) an almost fourfold increase from 4 July at this depth; however, rotifer abundance within the tailwater showed little change—103/1 on 4 July versus 102/1 on 18 July. Throughout August, ro- 121 Fic. 8.

In the tailwater, densities fluctuated from 21/1 to.80/1 to 39/1 on the same three dates, respectively. After 12 October, when drawoff was no longer re- stricted to the upper 3 m, the means of total rotifers in the main pool fluctuated in range of 60-85/1 with a maximum of 118/] occurring on 29 December. In the tailwater, the densities fluctuated from 8— 53/1. The increase that was observed in the main pool from 6 to 29 December was not reflected in the tailwater samples. A dominant rotifer genus, Keratella, was represented by 5 species. The high- est density of 127/I, all species combined, occurred on 18 July (Fig. 8). Keratella cochlearis was the only representative consistently found throughout the year. It was major component of the first rotifer pulse on 8 May with a mean of 47/] (Fig. 8), reaching a secondary maximum of 28/1 on 4 July. After 18 July, K. cochlearis fluctuated irregularly, being represented by usually less than 14/1. In the tailwater, K. cochlearis was er- ratic until 20 June, increasing sharply to a maximum of 43/1 on 4 July, producing another slight pulse of 21/1 on 29 August, continuing until 12 September. After this, it decreased sharply and fluctuated irreg- ularly, never exceeding 6/1. Keratella earlinae first appeared on 5 122 Fic. 9.

It constituted about one-third of the rotifers on 4 July (28/1) and on 18 July it was the dominant mem- ber of the genus (97/1 out of a total 127/ 1). The greatest density (344/1) was at 6 m with the lowest (2/1) at the surface (Fig. 8). Usually fewer than 5/1 were found af- ter turnover in October. Other species of Keratella that appeared sporadically in the tailwater and/or main pool areas and always in small numbers included K. americana and K. quadrata. Three species of Polyarthra were found during the study. All species combined, they were most numerous in May and December (Fig. 9). Polyarthra vulgaris 2oMue ae 229 Ne ee OANA Fic. 10.

The maximum (65/1) was found on 8 May. Polyarthra minor was present sporadically (Fig. 9) appearing in rela- tively significant densities (10/1 and 46/1 on only 2 occasions, 24 April, 29 Decem- ber, respectively). The only major in- crease of P. euryptera was on 4 July (16.1), (Fig. 9). Although it occurred in the samples on only 2 occasions in late spring, Conochi- lus unicornis was the major component of the 8 May rotifer pulse with a mean of 452/1. The maximum was 1,159/l at 3 m and the minimum was 52/] at 15 m (Fig. 10). It did not reappear until 18 July, but then persisted through September. Members of the genus Synchaeta were present primarily in April and after mid- July (Fig. 10). On 24 April, the largest number was 37/] at 3 m; 83% enumerated were from the surface and 3 m. These ro- tifers appeared in substantial densities on 1 August (13/1), on 15 August (24/l) and on 6 December (40/1). Representatives of the genus Brachio- nus were observed in the spring, fall, and early winter (Fig. 10). Brachionus caly- ciflorus was the only species sampled from March through April. It was found again only in December and January with the largest number on 29 December (33/ 1). Even though B. angularis was the only species present consistently from July to August it was very rare (less than 1/l) as was B. havanaensis (4 July). Kellicottia bostoniensis occurred irreg- ularly and in low numbers until after the fall turnover was initiated around 12 Oc- ROTIFERS IN KENTUCKY—Abel and Prins tober (Fig. 11). A maximum of 29/] was found on 24 October, with most occurring at 14 m. After 19/] were found on 14 No- vember, there were usually fewer than 1/1 during the remainder of the study. Other rotifers that were few in number and/or occurred at irregular times were: Asplanchna sp., Ploesoma sp., Hexarthra mira, Conochiloides sp., Filinia sp., Phil- odina (Rotaria?) sp., Cephalodella sp., Trichocerca spp., and Collotheca muta- bilis. In addition, rotifers found in sup- plemental samples not taken on routine sampling dates were: Lecane cervicornis, Platyias (=Brachionus) patulus, P. quad- ricornis, and Notholca spp. DISCUSSION Factors which may have influenced the vertical distribution of rotifers included the presence or absence of stratification particularly in reference to dissolved oxy- gen concentration and temperature. Dur- ing the period of July through September the largest numbers of rotifers were found at 6 m. From Duncan’s New Multiple Range Test (3) it was shown that the den- sities of rotifers at 6 m were significantly different from the densities at all other depths except 3 m (3 m did not differ sig- nificantly from the remaining depths). The diel study conducted on 18-19 July revealed that at least at that time the higher densities at 6 m persisted over a 24-hour period. However, diel studies in April and January indicated that rotifers were uniformly mixed in the water col- umn. These latter two periods of non- stratification were characterized by high turbidity, low light, and circulation of the water by winds. The latter two factors have been suggested by Kikuchi (4) to be present during periods of very little ver- tical movements by rotifers. The circu- lation within the water column may have promoted a homogeneous vertical distri- bution. Temperature distributions may have influenced the tendency for rotifers to ag- gregate at 6 m. The largest concentrations of rotifers in the metalimnion throughout the summer suggests a preference for this 123 region. The laboratory studies of Harder (5), which showed an aggregation of zoo- plankton at temperature interfaces, might suggest a possible explanation for the consistently large numbers in the meta- limnetic region, which is a temperature interface between the epilimnion and the hypolimnion. In the 13-month study, species diver- sity of rotifers was greatest from June through mid-October. The period of greatest species diversity occurred when water temperatures reached their maxi- ma. During this period, discharge vol- umes from the impoundment were low and restricted to the upper 3 m (Fig. 1). Such low discharges normally would have been accompanied by a slow flushing rate and, correspondingly, a higher rate of sedimentation in the upper reservoir sim- ilar to that reported in Lewis and Clark Lake (6). In the main pool area there was a decrease in turbidity, an increase in Secchi disc transparencies, and increases in temperatures accompanied by thermal stratification. Ackefors (7) observed that maximum species diversity occurred from July through September in the northerm Bal- tic. He suggested that it was closely as- sociated with the short, warm water pe- riod. These data may be instructive, since Pennak (8) has reported that species di- versity in lakes is very similar regardless of latitude or altitude. A greater variety of plankton was associated with warming of water by Robinson et al. (9) in their studies on the influence of artificial de- stratification on plankton populations in impoundments. The following rotifers were most per- sistent and characteristic of Barren River Reservoir during the study: K. cochlear- is, P. vulgaris, and K. bostoniensis. The following were typical summer forms, oc- curring from June through September: K. americana, Ploesoma sp., H. mira, K. crassa, and B. angularis. Some rotifers were characteristically epilimnetic in distribution: C. unicornis, Synchaeta spp., Asplanchna spp., and K. crassa. Cold-water forms included: K. quadrata, K. bostoniensis, and P. minor. 124 The surveillance of zooplankton activ- ities within a reservoir by sampling from the tailwater is an important means of measuring annual loss in discharges (10). The comparability of numbers in the res- ervoir and tailwater would appear to be very important if such an estimate of dis- charge loss is to be measured. In Barren River Reservoir, the unique factor of dis- charge level may affect such an estima- tion of loss. Since discharge from April through September was restricted to the upper 3 m, rotifer concentrations observed in this region of the main pool were compared with those in the tailwater. By means of Student’s t test (3) it was determined that from June to mid-October numbers from the tailwaters and the mean numbers in the upper 3 m of the main pool were not significantly different. Furthermore, den- sities of rotifers found in the tailwater seemed to reflect those found in the sur- face samples more than those at 3 m. This might have been due to the orientation of the cone attached to the upper dis- charge port; i.e., with an upward facing opening at 3 m, water would have been drawn from the overlying surface layers, particularly during low discharges. In a study conducted by the TVA En- gineering Laboratory on Nolin Reservoir, Kentucky, an impoundment with a simi- lar multilevel discharge capacity, dis- charges of 540 cfs from the upper 3 m were shown to have a velocity profile ex- tending to 5 m within the reservoir (11). Hypolimnetic discharges of 50 cfs in Bar- ren during the same study were too small to measure the influence of velocity. Since discharge rate in Barren River Reservoir remained at 50 cfs from late May to mid- September, the withdrawal was probably from the region much shallower than 5 m. Consequently loss of rotifers from the reservoir was probably minimal because the greatest densities tended to occur be- low this depth. Qualitatively, plankters in the tailwater and in the main pool were very similar because rotifers did occur throughout the water column even though most concen- trated at 4 m to 6 m. Consequently, a TRANS. KENTUCKY ACADEMY OF SCIENCE 44(3-4) qualitative survey of the main pool from the tailwater during upper level dis- charges would be feasible. However, quantitative data probably would pro- duce underestimates if the cone were in place due to the apparent exclusion of the bulk of rotifers from depths below the cone.

ABSTRACT Surveys of streams in Kentucky over a 7-year period resulted in new records and range exten- sions for 14 fish species, 10 of which are rare or poorly known. New records for Lepisosteus oculatus, Esox niger, Notropis venustus, Ictalurus nebulosus, Fundulus notti, Lepomis margi- natus, and Percina shumardi are reported from the Jackson Purchase. A range extension within the Cumberland River drainage is noted for Ichthyomyzon greeleyi. Hybopsis dissimilis and Notropis ariommus are reported from the Salt River drainage for the first time since 1892. The ranges of Notemigonus crysoleucas, Typhlichthys subterraneus, and Percopsis omiscomaycus are extended, and a population of Ammocrypta pellucida in the Little Sandy River is discussed. INTRODUCTION Since 1975, members of the Kentucky Transportation Cabinet, Division of En- vironmental Analysis, have made collec- tions of fishes from streams in Kentucky. Due to the continued threat of pollution to the streams of the Commonwealth from coal mining, petroleum exploration, stream dredging, land clearing, and other activities and the recent publication by the Kentucky Academy of Science of a list of fishes Endangered, Threatened, and Rare in Kentucky (1), we felt the fol- lowing distributional records worthy of note. ACCOUNTS OF SPECIES This paper reports new drainage rec- ords, adds localities for several fishes of concern, and confirms the presence of 2 species not recorded from the Salt River drainage since Woolman’s collections in 1890 and 1891 (2). Records are based on collections deposited in the Kentucky Transportation Cabinet, Division of En- vironmental Analysis Museum. Nomen- clature follows Robins et al. (3).

Green river drainages and from the Little South Fork of the Cumberland River drainage (4, 5). On 9 May 1980, 4 adults of this lamprey were taken from the Rockcastle River about 4 km downstream from Billows. Specimens came from 2 shallow (30 cm) riffles where a large number of lampreys appeared to be con- structing nests by moving small stones. The status of this species in Kentucky was listed as Undetermined by Branson et al. (1). Lepisosteus oculatus (Winchell). Spot- ted gar. This gar, reported as rare in west- erm Kentucky (5) and listed as Threat- ened by Branson et al. (1), has been recorded from Bayou du Chien (6), the lower Cumberland River drainage (7), the Tradewater River drainage, and the low- er Green River drainage (8). Due to its presumed rarity, all of our collections are listed as follows: 1 from a tributary of Bayou du Chien, Fulton County, 1.2 km WNW from Halfmoon Pond, 14 June 1979; 1 from Dry Lake (Prehistoric Ca- nal), Hickman County, at Whaynes Cor- ner, 24 August 1978; 1 from Back Slough, Carlisle County, 1.8 km NE of Laketon, 13 June 1979; 1 from Three Ponds, Hick- man County, 2.9 km NW of Whaynes Cor- ner, 24 August 1978; 10 from an unnamed roadside slough, Fulton County, along KY 94, 1.4 km NE of the point where KY 94 crosses into Tennessee between Tyler and Miller, 12 June 1979; 11 from an un- named roadside pool, Fulton County, 305 m E of Miller along the S side of KY 1282, 125 126 21 August 1978; and 1 from Clarks River sloughs, Marshall County, adjacent to US 641 at Benton, 10 March 1980. The larg- est numbers were taken within the Reel- foot National Wildlife Refuge from 2 small seasonal pools, abundant with sub- mersed and emergent aquatic vegetation, which are inundated by flood water from Reelfoot Lake. Esox niger Lesueur. Chain pickerel. The chain pickerel was known from 4 lo- calities in Kentucky: Middle Fork of Clarks River (9) and 3 oxbow lakes in McCracken, Ballard, and Carlisle coun- ties (10). We took 2 specimens from an unnamed tributary of Bayou du Chien, Fulton County, 1.22 km WNW of Half moon Pond, 14 June 1979: 8 were cap- tured with 2 Esox americanus Lesueur from Whaynes Branch, Hickman County, 610 m E of Whaynes Comer, 15 June 1979: and 1 was taken from Three Ponds, Hickman County, 24 August 1978. Whaynes Branch was a sluggish stream with banks heavily overgrown with bald cypress and a substrate of silt and organic debris. In contrast, the unnamed tribu- tary of Bayou du Chien had a substrate of very deep silt with little organic debris and little shade-providing vegetation. Branson et al. (1) considered this periph- eral species to be Threatened. Hybopsis dissimilis (Kirtland). Stream- line chub. The only record of this fish from the Salt River drainage was that of Woolman (2) who reported it as very rare in Rolling Fork. On 22 April 1980, we took an individual from a swift, rubble- bottomed riffle in Rolling Fork just downstream from the KY 412 bridge, Marion County, and M. L. Warren, Jr. and R. R. Cicerello captured 10 approximate- ly 1.7 stream km upstream from the KY 55/US 68 bridge, Marion County, 21 Sep- tember 1982 (pers. comm.). Notemigonus crysoleucas (Mitchill). Golden shiner. According to Burr (5), there were no records of this species in Kentucky east of the Kentucky River drainage. We captured 7 individuals in an unnamed slough near the US 23 cross- ing of Grays Branch in Greenup County on 7 September 1978. It was abundant TRANS. KENTUCKY ACADEMY OF SCIENCE 44(3—-4) and was the only species observed. Though possibly introduced at this loca- tion, it likely is native since Trautman (11) stated that this shiner was present in the Ohio counties bordering the Ohio River before 1900. Notropis ariommus (Cope). Popeye shiner. This fish has been collected from the Salt River drainage only by Woolman (2) who took it from Rolling Fork. We col- lected 1 specimen from Cloyds Creek at the KY 412 bridge in Marion County, 22 April 1980. It was seined from shallow water over a substrate of gravel and small rubble. Cloyds Creek is a small tributary of Rolling Fork. The status of the popeye shiner is listed as Undetermined (1). Notropis venustus (Girard). Blacktail shiner. According to Burr (5), this fish was known from Bayou du Chien, the Missis- sippi River, and the lower Ohio River. On 19 March 1981, we seined the lower section of Sugar Creek, Mayfield Creek, and what was apparently the remains of the old, unchannelized Mayfield Creek; all near the US 62 bridge over Mayfield Creek about 1.6 km S of Lovelaceville, Ballard County. The shiners (Notropis) collected were 2 N. stramineus (Cope), 3 N. whipplei (Girard), and 1 N. venustus. Branson etal. (1) listed the blacktail shin- er as a peripheral species of Special Con- cern. Ictalurus nebulosus (Lesueur). Brown bullhead. Burr (5) reported this catfish as sporadic from the lower Cumberland River to the Licking River. He did not include the records from the Jackson Pur- chase, i.e., those of Woolman (2) from Bayou du Chien and Mayfield Creek, be- cause no specimens are extant (B. M. Burr, pers. comm.). On 12 June 1979, we col- lected 17 brown bullheads from an un- named roadside slough in the Reelfoot Lake drainage about 1.4 km NE of where KY 94 crosses into Tennessee between Tyler and Miller, Fulton County. The slough had an abundance of aquatic vegetation, a mud bottom, and clear water. Brown bullheads were the only ictalurids captured. Typhlichthys subterraneus (Girard). Southern cavefish. Known in Kentucky DISTRIBUTION OF KENTUCKY FISHES—Rice et al. from caves in Barren, Edmonson, Hart, Warren (Upper Green River drainage), and Pulaski (Upper Cumberland River drainage) counties (5), Cooper (12) in- cluded localities for it in the Lower Cum- berland and Lower Tennessee river drainages in Tennessee. On | May 1981, we collected 1 specimen from Big Sul- phur Cave in Trigg County about 2.44 km W of Peedee on the North side of a bend of the Little River. The subterranean stream is part of the Lower Cumberland River drainage. According to David L. Swofford (pers. comm.), he and Gregory A. Sievert collected 4 specimens from the cave in the summer of 1979 (specimens not extant). This species was considered Threatened by Branson et al. (1). Percopsis omiscomaycus (Walbaum). Trout perch. The trout perch was known from the Green, Salt, Ohio, Licking, and Little Sandy river drainages and from the Big Sandy River drainage only as far up- stream as Little Blaine Creek (5, 13). In May of 1978, Ron Cicerello, Lewis Korn- man, and the authors captured 7 speci- mens from Right Fork of Beaver Creek 762 m E of Eastern in Floyd County, ex- tending the range approximately 110 km upstream into the Levisa Fork Big Sandy River drainage. The fish were seined from pools over substrates of sand and fine gravel. It was listed as a peripheral species of Special Concern by Branson et ale): Fundulus notti (Agassiz). Starhead top- minnow. Branson (14) reported this fish from Murphey’s Pond (Obion Creek drainage) in Hickman County and Sisk (15) reported it from Open Pond (Reel- foot Lake drainage) in Fulton County. In June of 1979, we collected it from 2 ad- ditional localities in the Reelfoot Lake drainage: 3 from an unnamed roadside slough about 1.4 km NE of the point where KY 94 crosses into Tennessee in Fulton County; and | from a small stream that drains Blue Pond into Running Slough near the KY 311 bridge 670 m S of the intersection of KY 311 and KY 1282, Fulton County. R. R. Cicerello and M. L. Warren, Jr. reported taking 5 individuals from Running Slough, Fulton County, at 127 Ledford, 24 June 1982 (pers. comm.). This topminnow was considered a species of Special Concern by Branson et al. (1). Lepomis marginatus (Holbrook). Dol- lar sunfish. This fish of swamps and slug- gish streams (16) was known in Kentucky only from Murphey’s Pond (10) and Ter- rapin Creek (5). On 15 July 1982 we pre- served 7 of 15 specimens seined from a spring-fed, perennial pool in Graves County 1.9 km NE of Kaler. The pool was within a lowland swamp, composed pre- dominantly of saturated ground with emergent hydrophytes and some wetland shrubs and trees, that is inundated sea- sonally by flood waters from the West Fork of Clarks River. The 65 m long, 9 m wide pool had a substrate heavily domi- nated by firm clay with minor amounts of silt and silt mixed with gravel. The water was clear and lacked any aquatic vege- tation although sweet flag, Acorus cala- mus L., tearthumb, Polygonum sagitta- tum L., and rice cutgrass, Leersia orizoides (L.) grew on the banks to the water's edge. Two months previous to our collec- tions (May 4), R. R. Cicerello and M. L. Warren, Jr. seined 1 specimen from an unnamed wetland approximately 7.3 km S of our site (pers. comm.). This wetland was being drained and was located adja- cent to West Fork of Clarks River 0.9 km ENE of Clear Springs, Graves County. These are the first records of the species from the Tennessee River drainage in Kentucky although Bauer (16) reported it from that drainage in Tennessee. Bran- son et al. (1) listed it as Threatened in Kentucky. Ammocrypta pellucida (Putnam). East- em sand darter. This darter is known in Kentucky from the Ohio, Big Sandy, Roll- ing Fork, Kentucky, Licking, Green, Cumberland, and Little Sandy river drainages (17). As reported in Branson et al. (18), we took this fish from the Little Sandy River between Grayson and Argil- lite. Four sites yielded 9 specimens from clean sand in gentle to moderate current. Additionally, M. L. Warren and R. R. Ci- cerello took 3 adults near Pactolus on 14 September 1982 (pers. comm.). Accord- 128 ing to Burr (5), the eastern sand darter is rapidly declining in numbers in the state. However, in the Little Sandy River downstream of Grayson Lake, a relatively intact population of this species appears to exist. The species was listed as Threat- ened by Branson et al. (1). Percina shumardi (Girard). River dart- er. Within the Jackson purchase, this spe- cies was known previously from only Obion Creek (2). On 15 June 1979 we collected 4 immature specimens from a backwater slough of Bayou du Chien, about 3 km NW of Fulton County High School, Fulton County. ACKNOWLEDGMENTS A. W. Berry, W. E.

TRAUB Department of Geology, Eastern Kentucky University, Richmond, Kentucky 40475 ABSTRACT The Strodes Creek Member of the Lexington Limestone is a body of irregulary bedded lime- stone and shale exposed in several outcrops in north-central Kentucky. Field observations, along with study of 98 polished slabs and 113 thin sections were used in order to study the depositional environment of the Strodes Creek Member and its relationship to the enclosing Millersburg and Tanglewood Limestone members. The Strodes Creek Member consists of 8 microfacies: an algal boundstone, a claystone, a dolomitic ostracode packstone, a dolomitic packstone, a dolomitic wackestone, a dolomitic carbonate mudstone, a Tetradium packstone, and a skeletal grainstone which represent various subenvironments within a shallow water, slightly restricted and shel- tered depositional framework. Regression-analysis techniques and a detailed description of the steps involved, including hypothesis testing and stepwise regression, were used to statistically verify the microfacies classification. INTRODUCTION Petrographic analysis and its related procedures are commonly used to pro- vide the basic information in formulating environments of deposition. Oriented thin sections and slabs derived from outcrop and core samples represent the major source of petrographic information. In addition to various classification schemes, point counts are usually performed on thin sections to obtain data for statistical analysis. Various statistical methods are commonly used. However, the use of multiple linear regression techniques can provide a wealth of information that is not easily obtainable by other techniques. Multiple linear regression can be used to establish relationships among point-count data parameters and categorical or con- tinuous variables. Regardless of the na- ture of the variable, however, any hy- pothesis can be tested by the regression approach so long as the least-square ap- proach with a single criterion is used. PETROGRAPHIC APPLICATIONS The Upper Ordovician Strodes Creek Member of the Lexington Limestone is a sequence of mud-dominated limestone and shale which is exposed at several lo- calities in north-central Kentucky. As with most units that have complex facies re- lations and have been under study for many years, the nomenclature has under- gone many changes. Figure 1 presents the general stratigraphy of the Blue Grass re- gion. The western edge of the Strodes Creek trends north-northwest between Winchester and Cynthiana, Kentucky (Fig. 2). The Strodes Creek appears to be a lens within the Millersburg Member of the Lexington Limestone throughout most of its occurrence. Relatively little work has been done on the petrology of the Strodes Creek Member. METHODS The study area encompasses those parts of north-central Kentucky where the Strodes Creek Member of the Lexington Limestone is exposed (Fig. 3). A total of 11 outcrops was described and measured for this study, and are located in five 7.5 minute geologic quadrangles. Each out- crop was sampled from the bottom to the top. A sample of each limestone in the Strodes Creek Member was collected from every outcrop, along with several samples of the interbedded shales. Where the member is well exposed at two loca- tions, samples were collected from both ends of the outcrop to better determine lateral variations. Where possible, sam- ples were also collected from the enclos- 129 130 TRANS.

Location of measured sections and western Insoluble residues were prepared from each shale sample and several limestone samples. A 2-gram sample was dissolved in 20% hydrocloric acid in order to obtain the insoluble portion. The shale samples were subjected to X-ray analysis by al- lowing a powdered sample to differen- tially settle in a water-filled cylinder, and then withdrawing the clay fraction with a pipet. This portion was then transferred to 3 slides and allowed to dry. In order to identify the clay minerals, 1 slide was left untreated, 1 was glycolated, and 1 was heat treated. Point-count data obtained through pe- trographic study were statistically ana- lyzed by application of regression analy- sis to perform hypothesis testing and stepwise regression to determine the va- lidity and significant characteristics of the microfacies. STATISTICAL ANALYSIS Multiple linear and stepwise regres- sion, as well as discriminative-analysis techniques, were used to determine if the microfacies, derived by petrographic ob- servation, were statistically valid; and if they were valid, what were the discrim- inating variables characterizing each mi- crofacies?

Stepwise regression allows the investi- gator to determine which variables are the best predictors for each of the microfa- cies. Forward stepwise regression was used to determine which allochemical and orthochemical variables would be the best predictors for each of the microfa- cies. The foward regression enters the in- dependent variables (allochems and or- thochems) only if they meet certain statistical criteria (alpha level set to 0.05). The order of inclusion is determined by the respective contribution of each vari- able to explained variance. By using this method, the maximum number of best predictor variables chosen was 3.

An F-test was utilized to test for significant relationships between MICRO 8 and various allochemical and orthochemical parameters. The assigned alpha level of 0.05 for a two-tailed nondirectional test was considered statistically significant. However, the employment of a correction for multiple comparisons was necessary, using the Newman and Fry (2) method.

The power for each predictor variable is listed in Ta- ble 3. The microfacies determined by pe- trographic observation were found to be statistically valid in all but one case (mi- crofacies 6), and this may be due to the presence of stromatoporoid, which re- sulted in unusually high counts of this allochem and resulted in lower counts of the matrix. Table 4 is example of the re- sults of the hypothesis testing and model comparisons for microfacies 8 for illustra- tive purposes. A Pearson correlation was performed on the allochemical and orthochemical vari- ables in each of the microfacies, and then related variables chosen by this function were compared to the predictor variables to check for multicollinearity. The pre- dictor variables were not found to be highly interrelated (Table 5), thus mul- ticollinearity and the limitations associ- ated with it were not seen as a problem in the study. CONCLUSIONS Multiple regression is a powerful and flexible technique for handling data anal- ysis. With researchers involved with many choices for statistical techniques, they should be able to justify the statistical procedure they select. This paper pre- sents multiple linear regression, which is unfamiliar or frequently misunderstood by many, as a basic research tool and clar- ifies selected steps in the hypothesis- and model-comparisons process. An example was made with a recent petrographic analysis of the Strodes Creek Member (Upper Ordovician) of the Lexington Limestone in north-central Kentucky to illustrate how these statistical techniques 134 TRANS.

SLOAN Departments of Agricultural Engineering and Forestry, University of Kentucky, Lexington, Kentucky 40546-0075 ABSTRACT A simple conceptual rainfall-runoff model was developed for predicting runoff from small, steep-sloped, forested Appalachian watersheds. The model requires only daily precipitation and an estimate of daily potential evapotranspiration, such as pan evaporation, as basic hydrological and meteorological inputs. The model was tested with 6% years of observed discharge and meteorological records from the 81.7 ha undisturbed Little Millseat watershed in the Eastem Mountain and Coalfield region of Kentucky. Three and a half years of records were used for calibrating the model and 3 years were used for validation. There was good agreement between the observed and predicted daily discharges, and the results demonstrate the ability of the model to simulate the “flashy” hydrologic response of this type of watershed. INTRODUCTION Within Kentucky, 116 daily read stream- gauging stations, 123 crest stage, and 102 low-flow partial-record stations are main- tained by the U.S. Geological Survey and other Federal and State agencies (1). In addition, a limited number of gauging stations are maintained for special pur- poses; for example, by the University of Kentucky for research. These gauging stations serve to monitor the flow of more than 16,000 km of flowing streams in Kentucky and are confined chiefly to larg- er streams and tributaries of the major river basins. It is economically impracti- cal to gauge every stream, especially first, second, and third order streams. Knowledge of the hydrologic behavior of ungauged streams and watersheds is very important to all persons carrying out, or potentially affected by, activities that disturb and modify the hydrologic bal- ance, whether it is for surface mining for coal, timber harvesting, road construc- tion, agriculture, or other forms of devel- opment. Federal and state regulation of these types of activities often mandate that baseline water quantity and quality char- acteristics be known and evaluated. To make such evaluations is an extremely difficult task, particularly on the un- gauged watersheds that comprise the ma- jority of the potentially affected wa- tersheds in eastern Kentucky. Studies by Springer and Coltharp (2) and others of the hydrology of small watersheds in eastern Kentucky have shown the “flashy” behavior of streams in this region, with quick-flow accounting for almost half the total runoff volume. Flooding is a com- mon problem in many of the eastern Ken- tucky watersheds. One cost-effective method of determin- ing the hydrological character of a wa- tershed is via the use of simulation models. These models predict watershed discharge (and quality) as either deter- ministic or stochastic functions of precip- itation and other variables that are more readily and cost-effectively measured than discharge. The application and/or evalu- ation of a number of deterministic rain- fall-runoff models on watersheds in Ken- tucky has been reported, including Haan’s Water Yield Model (3), the TVA Daily Streamflow Simulation Model (4), and the Stanford Watershed Model (5). The com- plexity of these rainfall-runoff models and their input data requirements vary, the internal time step in the model being an important factor. Generally, the smaller the time step, the greater the complexity of the model and the greater the input data requirements. Haan’s model pre- dicts monthly watershed yield and is the simplest of the three models. The TVA model predicts daily streamflow, while the Stanford model predicts hourly 135 136 PRECIPITATION Ys CMAX 4 fcee “® EVAPORATION INTERCEPTION THROUGHFALL. RUNO!

He could not prove that complex models give better results than simpler ones. However, he did demon- strate that neither the simple nor the complex models were free from failure in certain cases. In Kentucky, and many other parts of the United States, the majority of rainfall and runoff records are held as daily val- ues. Many of the questions concerning the baseline hydrological behavior of wa- tersheds can be answered using these daily data, or simple models that can pre- dict daily streamflow. Nuckols and Haan (4) reported poor results with the TVA Daily Streamflow Simulation Model (7) in Kentucky. The study reported herein is aimed at developing and validating a TRANS. KENTUCKY ACADEMY OF SCIENCE 44(3-4) simple raintall-runoff model, requiring a minimum of input data, that is suitable for predicting baseline streamflow from small steep-sloped forested Appalachian watersheds on a daily basis. The model was validated on the Little Millseat wa- tershed. DESCRIPTION OF THE MODEL The model, schematically illustrated in Figure 1 and mathematically formulated in Table 1, is a conceptual lumped-pa- rameter representation of the rainfall- runoff process. In this model, a wa- tershed is idealized as consisting of a series of interconnected water storages with the in- and outflow representing ac- tual physical processes. These processes are described using both physically and empirically based equations (Table 1). The concepts used in the model are com- mon to many daily rainfall-runoff models including those of BROOK (8, 9), BOUGHTON (10, 11), and MONASH (12, 13). These 3 models are the basis of the watershed model described herein. The model consists of 3 conceptual water stores or zones—the Interception Zone; the Soil Zone; and the Ground- water Zone—and has 13 parameters and 1 function (FCAN) that characterize the watershed. Definitions of these parame- ters are given in Table 2. Since snow is an insignificant form of precipitation in eastern Kentucky (2), the model does not account for snowfall or snowmelt runoff. However, the model could be modified easily to include a de- gree-day approach for representing this process. Precipitation is added to the intercep- tion store and any excess (throughfall) be- comes available for infiltration or runoff from the saturated source areas. The ca- pacity of the interception store is a func- tion of the maximum interception storage capacity (CEPMAX) and the degree of canopy development (FCAN). CEPMAX » is dependent on the type of vegetation and the maximum leaf-area and stem-area indices, and FCAN reflects the annual canopy growth characteristics and stem- area index.

The size of the saturated source area increases exponentially as the Soil Zone wet ups (i.e., as USIN increases). This source area consists of the stream area (FSTR) and the near-stream saturated zones that expand and contract in re- sponse to precipitation. This process is represented by the empirical equation proposed by Federer and Lash (8) and is represented by Function B (variable source area process) in Table 1. Overland flow from the saturated source area is subtracted from the precipitation excess, and the remainder represents the infiltra- tion into the Soil Zone. Infiltration rates in steep-sloped forested watersheds of the Appalachian region are very high and tra- ditional Hortonian (14) infiltration rarely occurs. The infiltration rates were there- fore assumed to be infinite. Drainage from the Soil Zone is depen- dent on the water content or water vol- ume of the soil zone (USIN) and in- creases exponentially as the water content increases.

The method assumes that, and is only valid if, the soil water retention function can be described by the relationship: h = a@-», where h is the pressure head, @ is the volumetric water content (USIN/US- MAX), and a and b are constants. This form of the equation was proposed by Gardner et al. (16). This relationship is only valid if the water retention function plots as a straight line on a log-log scale. If the first equation is a valid represen- tation of the water retention curve then Campbell's equation can be used to es- timate the hydraulic conductivity. Camp- bell’s equation is: FFU = FU6?>*?, where FFU is the hydraulic conductivity (Soil Zone drainage rate), FU is a coefficient, and the other variables are as previously defined. The function is the same as that describing Function C in Table 1. The water draining from the Soil Zone is di- vided between interflow and percolation to the Groundwater Zone. This division is assumed to be a fixed fraction, K1, of the total drainage, FFU.

Little Millseat Watershed. is limited by either the atmospheric de- mand (potential evapotranspiration) or by the plant available water (USIN-USWP, where USWP is the wilting point water content). The evapotranspiration is equal to the lesser of either the available water divided by a rate constant (ERATE) or the potential evapotranspiration (Func- tion D, Table 1). In the model, potential evapotranspiration is estimated from the input daily pan evaporation. Many tech- niques for estimating potential evapo- transpiration have been proposed (17, 18, 19) and could be used if the required in- put data were available. The model is not sensitive to the natural daily variation of potential evapotranspiration, but it is sensitive to the long term average evapo- transpiration rates over periods of months and years. Groundwater movement is modeled by a groundwater store with no fixed capac- ity (SSIN). Groundwater recharge occurs by percolation from the Soil Zone to the Groundwater Zone. Water is subsequent- ly lost from the store as baseflow to the stream (groundwater flow) or deep seep- age. Deep seepage models the loss of water to underlying aquifers and the un- gauged water flowing beneath the river bed. The normal groundwater storage- discharge relationship used in this type of rainfall-runoff model is linear, but Por- ter and McMahon (12) argue that within many watersheds more than one ground- water source or storage exists, leading to nonlinear behavior of the groundwater 139 flow component. A nonlinear discharge function is therefore used in the model (Function E, in Table 1). The ground- water drainage is linearly divided (K2) between baseflow and deep seepage. DESCRIPTION OF THE LITTLE MILLSEAT WATERSHED The Little Millseat watershed, located in the University of Kentucky's Robinson Forest in the Eastern Mountain and Coal- field region of Kentucky (Fig. 2), is 81.7 ha in area and is characterized by steep slopes, narrow valleys, and a southeast aspect (20). The hill-slopes average about 42% and the channel slope is about 6% (21). The soils of the watershed are similar to those of the adjacent Field Branch wa- tershed (40.5 ha) which are comprised mainly of the Shelocta, Gilpin, DeKalb, Sequoia, and Cutshin soil types (22). All these soils have moderately rapid to rap- id permeabilities (23). The Shelocta-Cut- shin series, a cove association, varies in depth from about 1.22 m to 1.83 m, the Shelocta-Gilpin association averages 1.40 m deep, and the DeKalb-Sequoia series, a ridge top association, is the shallowest at about 1.00 m (22). Smith (22) found the average weighted soil depth in Field Branch watershed to be about 1.07 m, with the wilting point and field capacity water contents averaging about 12% and 30% by volume, respectively. The aver- age total porosity is about 46% by vol- ume. The deepest soils occur along the upslope sides of benches and in cove sites, while rock outcrops are common along slopes and outslope edges of benches (2). The bedrock is comprised of alternating layers of sandstones, silt- stones, shales, and coal of the Pennsyl- vania Age (24). Vegetation in the watershed is domi- nated by the White Oak—Red Hickory type. Cove sites consist of the Yellow Poplar type and ridge-tops and upper southwest exposures are classified as Shortleaf Pine—Oak type (25). A complete list of tree species found in Robinson Forest has been compiled by Carpenter and Rumsey (26). 140 TRANS.

RESULTS AND DISCUSSION The hydrologic and meteorological data used by the model and used to validate the model included daily precipitation, daily pan evaporation and mean daily streamflow. Precipitation was measured with a weighing-bucket type gauge lo- cated in a clearing near the confluence of the Little Millseat and Field Branch wa- tersheds (Fig. 2). Continuous streamflow was measured with a permanent 3:1 side- slope, broad-crested V-notch weir, equipped with a FW-1 water level re- corder. The weir has a rated head of 0.9 m, which corresponds to a flow capacity of 4.83 m?/s. Daily evaporation measure- ments, in the form of pan evaporation data, were obtained from Buckhorn Res- ervoir in Perry County, Kentucky, about 30 km southwest of the Little Millseat Watershed. A split-record technique was used to evaluate the rainfall-runoff model. One section of the 6% years of available re- cord was used to calibrate the model (Aug. 1971 to Dec. 1974), while the remainder was used to independently evaluate model performance (Jan. 1975 to Dee. 1977). The input parameters of the model were first estimated from the physical charac- teristics of the watershed described ear- TABLE 4.—STATISTICAL COMPARISON OF MODEL PERFORMANCE Optimization Period Test Period Statistic Monthly Daily Monthly Daily Mean* 20.89 603.5 19.82 21.26 579.8 19.04 Standard Deviation* 686.2 52.40 565.1 $3.15 600.6 39.73 490.9 Coefficient of Variation 11078!

Individual pa- rameters and groups of parameters were then adjusted so that the predicted and observed hydrographs showed good agreement. It was found that a visual comparison of the observed and predict- ed hydrographs, although subjective in nature, was the most effective means of optimizing the model’s parameters. Fi- nally, the steepest ascent method of au- tomatic optimization (11) was used to re- fine the parameter set. The sum of squares of the errors in the daily flows was the objective function for this optimization. The final parameter set is presented in Table 2. From this table it can be seen that the limited optimization produced very little change in the parameter set. The main effect of the optimization was to modify the peak flows, and determine the appropriate values of CEPMAX and FU, for which little information was ini- tially available. Evaluation of the standard of simula- tion achieved by a watershed rainfall- runoff model is difficult because stream- flow provides a large amount of data of a range of types (27), and no one test will satisfactorily evaluate all types (e.g., peak flow, low flow, mean flow, etc).

Many of these statistical and graphical tests are described by Aitken (28), WMO (29), Moore and Mein (30), and Weeks and Hebbert (27), and the reader is referred to these citations for more complete de- tails of the methods. Tables 3 and 4 present the annual sum- mary and the optimization/test period summaries, respectively, on a monthly and daily flow basis.

This example represents the worst simulation for the test period in terms of the coefficient of determina- tion of the daily flows (72 = 0.724), and the predicted peak flows.

The mean flow and the standard devia- tions of the observed and predicted monthly flows are in good agreement on an annual basis (Table 3) and during the optimization and test periods (Table 4). However, the standard deviations of the daily flows predicted by the model are significantly lower than the observed (Tables 3 and 4). For example, the coef- ficient of variation (standard deviation/ mean) of the observed flows are 2.508 and 2.177 for the optimization and test pe- riods, respectively, whereas those for the predicted flows are 1.868 and 1.533, re- spectively. Hence, the observed flows ex- OPTIMIZATION PERIOD #——4 TRANS.

The coefficients of determination (r?) of the monthly and daily flows are uniform- ly high, averaging about 0.92 and 0.80, respectively. However, neither the mean, standard deviation, or coefficient of de- termination can indicate if there is bias, or systematic errors, in the predicted flows. Aitken (28) indicated that the coef ficient of efficiency (E) could be used to detect bias. If the coefficient of efficiency is less than the coefficient of determina- tion then bias is indicated. Table 4 shows that in all cases the coefficient of efficien- cy is slightly less than the coefficient of determination, indicating a small bias in RUNOFF PREDICTION IN KENTUCKY—Moore et al. 200 143 1976 —— PREDICTED a ° (m/s x 10%) {00 50 AVERAGE DAILY DISCHARGE JAN FEB MARCH APRIL MAY JUNE — — — OBSERVED JULY AUG SEPA OCT Fic. 6.

The technique is based on the number of runs of residuals of the same sign which the data set exhibits. The expected number of runs is normally distributed, and a Chi- square test indicates systematic errors. If the magnitude of the normalized variate (Z in Table 4) is greater than 1.96, then the number of runs is significantly differ- ent from that expected for random errors at the 0.05 level of statistical significance. Table 4 shows that |Z| > 1.96 for the dai- ly ows during both the optimization and test periods, thus indicating a small amount of bias in the model. This finding is consistent with the comparison of the coefficients of determination and effi- ciency. Weeks and Hebbert (27) described the maximum error of the model statistic (K in Table 4) and showed that it can be in- terpreted as being equivalent to a con- stant error in the results. Table 4 shows that the maximum error of the model ranges from 23 to 26% for the monthly flows and 70 to 73% for the daily flows. As expected, the daily flows exhibit a rel- atively high error. The monthly predicted and observed runoff (Fig. 3), the daily flow duration curves (Fig. 4), and the residual mass curve (Fig. 5) all show very good agree- ment between the predicted and ob- served flows. The residual mass curve coefficient (R) measures the relationship between the sequence of flows and not simply the relationship between individ- ual flow events (28). The residual mass curve coefficients are reasonably high, averaging about 0.79 and 0.86 for the op- timization and test periods, respectively. During the period of record, 1971 to 1977, the maximum observed peak daily flow was 0.837 m?/s, and the correspond- ing peak predicted flow was 0.834 m/s. Generally, however, the extreme peaks were underestimated by the model, as is evident from an examination of the flow duration curves for probabilities of oc- currence of less than about 1%. Figure 6 shows that the hydrograph recessions and the timing of the peak flows are modeled very well. These results, plus the steep- ness of the flow duration curves, indicate that the model represents the “flashy” behavior of the watershed very well. This “flashy” behavior is characteristic of the 144 streams in Robinson Forest (2), and the Appalachian region in general. SUMMARY A daily rainfall-runoff model was de- veloped for predicting runoff from steep- sloped forested Appalachian watersheds. The model was validated on the Little Millseat watershed located in Eastern Kentucky, using a split-record technique. The initial estimates of the model param- eters, determined from the physical char- acteristics of the watershed, were very close to the optimized values, indicating the physical significance of their values. The results show very good agreement between the predicted and observed flows, and demonstrate the ability of the model to predict the “flashy” response of the watershed. The statistical and graph- ical comparison of the observed and pre- dicted flows indicated a slight bias, or systematic error, in the predicted flows.

The Effect of Temperature on the Rate of Development of Aphidius matricariae Haliday (Hymenoptera: Aphidiidae)' M. K. Girt, B. C. PAss, AND K. V. YEARGAN? Department of Entomology, University of Kentucky, Lexington, Kentucky 40546-0091 ABSTRACT The developmental rates of Aphidius matricariae Haliday at 9 constant temperatures, 10, 12.8, 15.6, 18.3, 21, 24, 26.7, 29.5, and 32 C, are reported. The developmental rates were fitted with a logistic curve (100/Y = (k/1 + e*~»*). The shortest time for development was 11.5 days at 26.7 C and the longest time was 41 days at 10 C. The duration of development decreased as tem- perature increased up to 26.7 C. At 29.5 C, developmental times slightly increased, and at 32 C, the parasite did not survive to the adult stage. Males developed significantly faster (P < 0.05) than females except at 26.7 and 29.5 C. INTRODUCTION Aphidius matricariae Haliday, an en- doparasite of the green peach aphid, My- zus persicae (Sulzer), has been utilized to control this pest in greenhouses (1, 2 and 3). The parasite has been reported to parasitize 40 different species of aphids ' This paper is published with the approval of the Director of the Kentucky Agricultural Experiment Station as Journal article no. 82-7-302.

Aphidius matricariae has been reported from hot deserts in Israel and Ivan (4) and from cool plains in England (5) and Canada (1), yet the effects of temperature on its de- velopment are not adequately reported. Rabasse and Shalaby (6) reported that the development of A. matricariae was slow- er in younger hosts (Myzus persicae) than in older hosts at 10 and 15 C, but the de- velopment was slower in older hosts at 20 C. Giri et al. (7) reported this parasite’s mating behavior and production of prog- eny under different temperature regimes.

(Stu- dent’s t-test). greenhouse. Mummified aphids were picked and placed in gelatin capsules (no. 00, Eli Lilly and Co.) individually so that emerging parasites could be sexed and mated. Ten mated female parasites, which had emerged within the past 24 h, were individually introduced into small cages containing 50 aphids/cage. Paper cartons (0.5 1) were used as par- asitizing cages. The root of a 2-leaf stage radish plant with 50 aphids was inserted into and sealed inside a 7.4 cc glass vial. The neck of the vial was then fitted into a hole cut in the paper container 3 cm below the upper rim. A similar hole was cut 2 cm above the lower rim and closed with a cork stopper. Filter paper was fit- ted tightly in the bottom of the cage. The top of the cage was covered with trans- parent plastic wrap which was punctured with insect pins to permit ventilation. The total duration of development was defined as the time required from the day of parasitism to the day of adult parasite emergence; this was determined at 10, 12.8, 15.6, 18.3, 21, 24, 26.7, 29.5, and 32 C. The time required to develop from the day of parasitism to aphid mummy formation was also recorded. This was done by checking daily for the formation of mummies. The duration of develop- ment at different constant temperatures was converted to rate of development per day to fit a temperature-developmental TEMPERATURE E\FFECTS ON APHIDIUS DEVELOPMENT—Giri et al. velocity curve. The temperature-time and temperature-developmental velocity curves were fitted using Davidson’s (8) equations Y = (1 + e?->*)/k and 100/Y = k/(1 + e# ?*), respectively, where Y = de- velopmental time, x = temperature, and a, b and k are constants. RESULTS AND DISCUSSION The rate of development of A. matri- cariae increased with higher temperature from 10 to 26.7 C, and then decreased at 29.5 C; at 32 C the parasite did not sur- vive to the adult stage (Table 1). When the duration of development from ovi- position to mummy stage (Y) was plotted against temperature (x), the line repre- sented the course of the temperature-time curve. When the reciprocals for devel- opmental time (100/Y), representing the average percentage development/day, were fitted with Davidson’s (8) logistic curve, the upper inflection appeared near 29 C (Fig. 1A). Similar logistic equations were used separately to fit data on de- velopmental rates from time of parasitism to adult male and female emergence (Fig. 1B & C) because there were significant differences in developmental time of males and females at temperatures from 10 to 24 C (Table 1). Wiacknowski (9) de- scribed similar differences in develop- mental time for male and female Aphi- dius smithi Sharma and Subba Rao. The threshold temperature was calcu- lated to be approximately 5 C by extrap- olation of a straight line from the most linear portion of the temperature-devel- opmental-velocity curve. The point at which this line intercepted the tempera- ture axis was assumed to be the threshold temperature. Based on this threshold temperature, degree-days were calculat- ed for mummy stage (from parasitism to mummy formation), and male and female adults (from parasitism to male or female emergence) as 142.4, 235.8 and 243.3, re- spectively. Results presented here and by Giri (10) indicate that A. matricariae can develop from 10 C to 29.5 C. At higher tempera- tures, development was terminated by the death of the host. The optimal tempera- ture in terms of the shortest develop- 147 mental period or the maximal rate of de- velopment was 26.7 C. However, considering the number of progeny pro- duced and survival (7) as well as the rate of development, 21 C is the optimal tem- perature for greenhouse rearing of the parasite.

VANENK Department of Microbiology, University of Kansas Medical Center, Kansas City, Kansas 66103 AND Dr. LARRY P. ELLIOTT Department of Biology, Western Kentucky University, Bowling Green, Kentucky 42101 ABSTRACT Yeasts were isolated and identified the 12-month period March 1978 through February 1979 from 5 sampling sites in the Barren River, Warren County Kentucky. Sporadic yeast counts were obtained that averaged 40 CFU/ml for the effluent, while the river averaged 15 CFU/ml. No seasonal variation in yeast counts was noted. A total of 318 yeast cultures were isolated and identified, including 16 different genera with Cryptococcus being the most common genus ob- served. The Barren River contained a characteristic yeast population which varied with several environmental factors at a statistically significant level, and the effluent released several patho- genic yeast species which were not indigenous riverine yeasts. INTRODUCTION The yeasts, or unicellular fungi, make up a substantial portion of the microbio- logical flora of soil and water. Several studies reported yeasts from rivers, but the data are contradictory with respect to the relationship between sewage pollu- tion and yeast numbers. Simard and Blackwood (1, 2) concluded that yeast counts in the St. Lawrence River varied over a 5-month sampling period but no consistent relationship was seen be- tween yeast counts and indices of pollu- tion such as coliforms, total bacteria, dis- solved oxygen (DO), and biological oxygen demand (BOD). Spencer et al. (3) sampled the South Saskatchewan River and concluded that several yeast species, including some possible pathogens, had originated from urban sewage. They suggested that the differences in yeast numbers and species between sites upstream and downstream of a city could be used to indicate the degree of biological pollution of the river contributed by the municipal sewage ef- fluent. Cooke et al. (4) surveyed the yeast flora of several sewage treatment plants and reported the presence of many yeast species that are considered opportunistic human pathogens. All these studies sug- gest that microbiological examination of rivers for water quality should not be lim- ited to the coliform test. The examination of yeast floras may also give valuable in- formation about river pollution. The purposes of this study were to ex- amine the Barren River for the presence of yeasts; to determine whether the Bowling Green sewage treatment plant in southwestern Kentucky was contrib- uting high numbers or unique species to the natural river yeast flora; and td at- tempt to correate selected physical- chemical and biological features with riv- er yeast counts. MATERIALS AND METHODS Description of Sample Area The Barren River drains 5,853.4 square km of primarily agricultural land in Southwestern Kentucky. It flows at an av- erage rate of 91,918 | per second through Bowling Green, Kentucky before joining the Green River, a tributary of the Ohio River. The water level of the Barren Riv- 148 RIVER YEASTS IN KENTUCKY—VanEnk and Elliott er is controlled by an Army Corps of En- gineers dam located 66.1 km upstream from Bowling Green. The Bowling Green municipal sewage treatment plant discharges 21 x 10° | of water per day into the water. All effluent receives primary and secondary treat- ment via an activated biological filter sys- tem, and automatic chlorination. Water samples were taken from 5 study sites established in the Barren River (5). Enumeration and Characterization Samples were taken from midstream in sterile bottles using the grab-sample technique. They were placed on ice and transported immediately to the Western Kentucky University Microbiology Lab- oratory for analysis. Yeast counts were determined by the spread-plate tech- nique by plating in triplicate 0.1 ml of each sample on petri plates containing Plate Count Agar (Difco, Detroit, Mi.) supplemented with 100 mg each of Chloramphenicol and Chlortetracycline (Sigma, St. Louis, Mo.) to inhibit bacte- rial growth (6). After incubation at 25 C for five days, all yeasts were counted and streaked for purification on Sabouraud Dextrose Agar (Difco). All specimens were identified using standard tech- niques (7, 8). The tests used for identifi- cation of the yeast isolates consisted mainly of the fermentation and assimila- tion of a battery of 12 carbohydrates. In addition, Barnett’s and Pankhurst’s (9) keys for the identification of yeasts were used. Physical-Chemical Characteristics of Water Samples Several environmental parameters were measured at each site. River height and velocity data were obtained from the Army Corps of Engineers, monitored dai- ly in Bowling Green. Dissolved oxygen was determined by the iodometric test, azide modification (10). Iron, nitrate, or- tho-phosphate, and turbidity were deter- mined using a Hach Direct Reading En- gineers Laboratory Kit (Hach Chemical Company, Ames, Ia.). Water temperature 149 TABLE 1.—COMPARISON OF YEAST COUNTS FROM FIVE SAMPLE SITES IN THE BARREN RIVER Standard Site Mean error Range Upstream 12 12.1 0-40 Effluent 40 73.5 0-300 Downstream #1 18 40.3 0-193 Downstream #2 13 21.9 0-103 Downstream #3 15 25.1 0-116 and pH were determined for each sam- ple, and effluent chlorine content data were kindly supplied by treatment plant personnel. Total viable aerobic bacteria counts were done on each sample using the spread-plate technique on Plate Count Agar (Difco). Statistical Analysis The data were analyzed as previously described (5) by computer which per- formed means, standard deviations, ranges, analysis of variance, correlation analysis, and regression analysis. RESULTS AND DISCUSSION The most notable fact to emerge from the yeast-count data was the large amount of variability in the river bi-weekly via- ble yeast counts. These viable counts ranged from 0 to 300 colony forming units per ml (CFU/ml) with the effluent aver- aging 40 CFU/ml and the river sites av- eraging 15 CFU/ml. The upstream site yielded the lowest average counts and showed the least variability (Table 1). The sewage effluent exhibited both the high- est yeast count average and the greatest variability over the sampling period. The effluent counts seemed to have no rela- tionship to the river counts, suggesting that different factors may be controlling yeast numbers in the two sources. No seasonal trends were noted in total yeast counts. The St. Lawrence River also yielded approximately equal yeast num- bers throughout a 5-month study period (1, 2). In that study, however, certain yeast species, notably Rhodotorula spp., seemed to increase at some sites in late summer. In the Barren River, all yeast 150 TRANS.

This apparent lack of seasonal depen- dence indicated that factors other than temperature were the major determi- nants of yeast growth during the study. Rheinheimer (11) discovered a higher winter than summer count in the Elbe River of Germany, and suggested that competition for certain nutrients was more important than temperature in con- trolling yeast reproduction. He also pos- tulated that concentration of these nutrients was largely dependent on fast- growing algae, which are less populous in winter. Mean iron levels, DO, pH, and turbid- ity values were not statistically different from station to station (Table 2). No cor- relation was found between the iron, DO, and pH values and the yeast counts (Ta- ble 3); however, turbidity affected the yeast population. A maximum level of 0.3 ing/] iron in freshwater used for drinking purposes has been set (12). The mean iron levels did not exceed this limit. None of the DO values were lower than the min- imum allowable level of 5.0 mg/] that has been established for freshwater streams. All the pH values were within the limits set for freshwater streams of 6.0-9.0 (13). No standards were set for turbidity in streams. The mean nitrogen-nitrate level for the EFF was significantly higher (F = 8.818) than the means of the other 4 stations. This situation was also noted by Cherry et al. (14) who found high nitrate levels associated with effluent from sewage treatment plants. A limit of 45 mg/l nitro- gen-nitrate has been established for drinking water while averages must be below 10 mg/l to control eutrophication (12). A statistical correlation was found between the nitrate levels and the yeast counts. The mean phosphate level for the EFF was significantly higher than the other station means (F = 14.76). The recom- mended limit for phosphates in fresh- water streams is no more than 0.015 ml/I (10). The mean levels for phosphate ex- ceeded the set limit at all stations. A sta- tistical correlation was demonstrated be- tween the phosphate levels and the yeast counts. The mean of the EFF counts of total aerobic chemoorganotrophic bacteria iso- lated on Plate Count agar with the spread- plate technique was significantly higher RIVER YEASTS IN KENTUCKY—VanEnk and Elliott than the means of the other 4 stations (F = 3.48) (Table 2). The second highest mean was that of DS #1 which may have re- flected input of organisms from Jennings Creek or cells washed downstream from the EFF. Water from the Lost River Cave complex resurges near Dishman Mill on Jennings Creek. Elliott (15) found these waters to have an average total coliform count of over 5,000/100 ml, the maximum allowed by the Kentucky Water Commis- sion for public water supplies. All fecal coliform densities were greater than the recommended maximum of 200/100 ml for contact recreation in Kentucky. Lovan et al. (16) found the mean total coliform count of Jennings Creek to be 641,950/ 100 ml and the fecal coliform count to be 17,375/100 ml. The mean chlorine level was 0.60 ppm. Since chlorine was measured only at EFF, no statistical analysis between chlorine levels and yeast counts at the other sta- tions was done. A negative correlation was found between chlorine levels and yeast counts. This is not surprising, since Jones and Schmitt (17) demonstrated that 100% of 10° Candida albicans cells per ml were killed when exposed to 4 ppm of chlorine for 30 minutes. The average flow rate over the year-long sampling period was 91,918 I/sec. It was assumed that the river flow registered at the monitoring station corresponded to the flow rate at the sampling sites. A sta- tistical correlation between flow rate and yeast counts was significant (0.05 level). Of all the parameters tested, regression analysis revealed that only turbidity, ni- trate, and chlorine gave significant F-val- ues. These 3 variables seemed to have the most influence on yeast content, sug- gesting that several factors influence the rate of yeast growth in water and sewage. Nutrient concentration, reflected by ni- trate and turbidity, and levels of toxic chemicals, such as chlorine, appeared to be the most important. Since these fac- tors varied more in the sewage effluent than in the river, they likely made a large contribution to the increased variability in yeast counts seen in the effluent. 151 TABLE 3.—CORRELATION COEFFICIENTS OF MEA- SURED PARAMETERS VERSUS YEAST COUNTS Correlation Parameter coefficient Chlorine!

The river was shown to contain a nat- ural flora of yeasts with respect to the yeast isolated from the effluent, and the total number of yeasts was not signifi- cantly altered by release of treated sew- age effluent into the river. In this respect, the Barren River was similar to the St. Lawrence River, but differed from the South Saskatchewan River. A total of 318 yeasts among 16 genera were isolated and identified during the course of the study (Table 4). The genus Cryptococcus was the most frequently isolated genus (30%). The species Cryp- tococcus laurentii was the most common species. Other major genera represented were Candida (22%), Trichosporon (13%), Rhodotorula (9%), and Torulopsis (7%). These figures are unique in some re- spects, but quite similar to those ob- tained from other rivers. Lazarus and Ko- burger (6) found the Suwanee River in Florida to contain Candida (28%), Rho- dotorula (24%), Cryptococcus (16%) To- rulopsis (12%), and Trichosporon (3%). Simard and Blackwood (1, 2) found Rho- dotorula (57%), Candida (24%), and Cryptococcus (8%) in the St. Lawrence River. The South Saskatchewan River (3) contained Candida (25%), Rhodotorula (23%), Trichosporon (13%), Cryptococ- cus (7%), and Torulopsis (5%).

The most frequently found effluent yeast genera were Candida, Trichosporon, Crypto- coccus, and Rhodotorula, in decreasing order of frequency. The survey by Cooke et al. (4), found the order of occurrence in their effluent samples to be Candida, Rhodotorula, and Trichosporon. The results of this study also indicate that municipal sewage effluent may be a source of medically important yeasts. If one uses the API (API 20C, Analytab Products, Inc., Plainview, N.Y.) listing of 25-30 yeast species as being clinical iso- lates and potential pathogens in humans whose health is compromised, then the river contained 15 of such human-asso- ciated yeasts. Finding these yeasts in a 154 river is significant both as an indicator of possible human pollution of the river and as a potential source of yeast infections for humans in contact with the river water. From this group of 15 species, 7 consist- ed of Cryptococcus terreus, Candida zeylanoides, Trichosporon capitatum, Trichosporon penicillatum, Candida parapsilosis, Trichosporon cutaneum, Rhodotorula glutinis, the first 4 species being limited to the effluent only. Fifty six isolates of these medically important yeasts were also identified using a com- mercial yeast identification system (API 20C) in a comparison study with conven- tional methodology (18). The API 20C system, with computer assistance, iden- tified 100% of the isolates for which it was designed. Although the above species are considered potential pathogens, their virulence is quite low, and they pose minimal health hazards. The opportunis- tic yeast pathogen, C. albicans, was not isolated from any Barren River station. No other river studies reported its isolation except for the Long Island Sound estuary study where Buck et al. (19) reported its presence inside shellfish in polluted water.

Mitchell, Kentucky 41017 ABSTRACT The sine-Gordon equation was examined in a Kasner cosmological background. A one soliton solution is given. A procedure to obtain additional solutions is suggested. INTRODUCTION There has been much interest in the sine-Gordon (SGE) equation (1) over the last decade, partly due to the numerous and diverse applications (1) of the equa- tion. One area in which the SGE has been applied is the theory of elementary par- ticles. In this paper I examine the SGE in a cosmological background metric. The problem is not purely mathematical in nature because the effect of an expanding universe upon solitons propagating therein is of physical interest as well. Since we are solving the SGE in a given background metric, we are assuming the contribution to the background due to the energy-momentum tensor of the soliton field is negligible. METHODS We begin by examining the Einstein field equations for a source consisting of the self-interacting sine-Gordon field: Ruv — YguvR = K Ty (1) with Tuy = —d,ud,v + egpv- (b,0,* — 2M?sin*). (2) The sine-Gordon field itself satisfies the equation [V-g¢,"]u + V—g M’singd =0 (3) (4) Unfortunately, the system of equations (1), (2), and (3) is a highly non-linear set of partial differential equations the solution of which is generally very difficult. How- g = det guv. ever, if we assume that ¢ is small in am- plitude, we can effectively decouple the equations. In this case we first solve equation (1) for a vacuum metric (Tuy = 0) then solve the sine-Gordon equation (3) on this background metric. We are es- sentially assuming that the right hand side of (1) is essentially zero; that is, the influ- ence of ¢ upon the metric is a negligible perturbation, but ¢ is not so small that we must linearize the sind term in (3). In this case we can see non-linear effects in the propagation of @ without having to ac- count for the gravitational field generated by @. This is true, as an example, for water waves at the surface of the Earth. Here non-linear propagation does not mean that we must consider the gravitational field of the wave. Consider the special case of the vac- uum Kasner (2) line-element ds? = dt? — PPidx? — #Pdy? — 2?sdz? (5) where Di + Po + Ps = Dir + Po + pz = 1 In this case Vg =t. (6) For simplicity, we will assume that @ = o(t,z) only. In this case equation (3) be- comes dst + td, — t2?°h, 2, + M?sind = 0. (7) A futher simplification occurs if we choose p; = 0. This particular back- ground metric has been the object of study concerning the propagation of electro- 155 156 magnetic waves (3). Equation (7) be- comes in this case dbx + tb — RESULTS Before giving the solution to (8), we ex- amine the small amplitude case, @ < lI. In this limit sez + M?sind = 0. (8) sind =~ and equation (8) becomes Pst oF td, = Ps2z at Md = 0, (9) which is readily solved by standard tech- niques. The solution is = AJ,(Kt)exp[+ iVK? — M? Z] (10) where A and K are constants. In the asymptotic time limit, t > ~, the solution represents a plane wave propagating along the z-axis, as long as K* > M?. Returning to the exact equation (8), if we perform the complex coordinate transformation Z—1T tip, (11) equation (8) becomes 57 — spp — P ‘bsp + M?sin @ = 0. (12) This is just the (2 + 1) dimensional SGE where 7 is the time-like coordinate and p is the space-like co-ordinate. The solu- tion is (4) x a 2 @ = +2 cos-tsn al) = Bx).k| (13) K where a and @ are constants related to the Lorentz factor, y, and the wave speed, v, respectively, and sn is a Jacobian elliptic function sine amplitude of modulus K. Transforming to the original co-ordi- t la d@ = +2 cos ‘sn Bl, = nates we obtain K B One can use similar complex co-ordinate substitutions in order to utilize a proce- dure suggested by Liebbrandt (5) in or- der to obtain addition solutions to the SGE in this background. Leibbrandt has determined a method to obtain multi-so- TRANS. KENTUCKY ACADEMY OF SCIENCE 44(3-—4) liton solutions to the (2 + 1) dimensional SGE (12). In order to apply his technique one needs only to follow Leibbrandt to obtain the multi-soliton solution to equa- tion (12) and then apply the inverse trans- formation to obtain a multi-soliton solu- tion to equation (8). DISCUSSION AND SUMMARY In this note we have briefly examined the solution to the SGE in a cosmological background metric. The SGE in a special case of the Kasner anisotropically ex- panding background is related to the (2 + 1) dimensional SGE of flat space via a complex co-ordinate transformation. This relationship can be exploited in order to adapt a known solution of the (2 + 1) di- mensional SGE to the present case. A procedure recently proposed by Leib- brandt (5) can also be adapted in order to obtain multi-soliton solutions to the par- ticular SGE investigated here. The solution given here also has an ap- plication in a recent theory of gravity giv- en by Rosenbaum et al. (6). The sine-Gor- don field @ given here is related to the scalar field under consideration by Ro- senbaum and co-workers (6) by ig=0; +i = V-L. The solution(s) given here can, then, be applied to the investigation of that theory of gravity as well. LITERATURE CITED 1. Barone, A., F. Esposito, C. J. Magee, and A. C. Scott. 1971.

TOWLES Department of Biological Sciences, Eastern Kentucky University, Richmond, Kentucky 40475 ABSTRACT A new variant of Plethodon wehrlei was discovered in Letcher County, Kentucky and Summers County, West Virginia. The specimens from Kentucky represent a new state record for this species, and extend the known geographic range of the species by 85 km. This variant differs from other P. wehrlei in its possession of large, yellow spots on the dorsum. INTRODUCTION A new variant of Wehrlei’s salamander, Plethodon wehrlei, was found in SE Ken- tucky by D. T. Towles and in SW West Virginia by R. Highton. Highton (pers. comm.) collected a juvenile of this morph 4 km N of Hinton, Summers County, West Virginia on 8 May 1981. Subsequent vis- its to this site disclosed no additional specimens. Towles collected an adult and a juvenile on 13 June 1981 from a shale- rock cliff on a hillside above Line Fork Creek in Lilley Cornett Woods, Letcher County, Kentucky. Subsequent visits dis- closed only 6 additional specimens, 1 adult and 5 juveniles. The animals from Kentucky were found primarily at night on wet areas of the cliff face during and following periods of rainfall. The specimens had a brownish ground color with relatively large (1-2 mm), ir- regularly-shaped, yellow spots scattered over the dorsum and extending on to the upper portion of the tail (Fig. 1). In adults and juveniles, the yellow spots are usu- ally present at irregular intervals in 2 rows over the dorsum. Also, juveniles from the 2 separate localities in Kentucky and West Virginia are very similar in color pattern. There are many small, light spots on the lateral surfaces of the body, the sides of the head and under the neck, extending 1 Publication no. 8 from Lilley Comett Woods Ap- palachian Ecological Research Station, Eastern Kentucky University. down to the chest. The venter and un- derside of the tail are light gray. All spec- imens have 17 costal grooves and dis- tinctly webbed toes as is characteristic of P. wehrlei (1). Both adults were 52 mm in snout-vent length and 6.5 mm in head width. The juveniles averaged 31 mm in snout—vent length and 4.3 mm in head with (n = 6). Specimens from other populations of P. wehrlei are not known to have large, yel- low spots. Small, red spots are present on the dorsum of juveniles in some localities (1, 2, 3). Red dorsal spots are present in adult P. wehrlei in the southem part of their geographic range (1, 3, 4). Newman (4) described a red-spotted population from Montgomery County, Virginia as a distinct species, P. jacksoni, later syn- onymized with P. wehrlei (1). There is considerable variation of pigmentation in Fic. 1. Yellow-spotted variant of Plethodon wehr- lei from Kentucky. Scale = 10 mm. 157 158 P. wehrlei from various localities (1, Thomas Pauley pers. comm.). In the morph described here, the red is appar- ently replaced by a yellow pigment. The reported geographic range of P. wehrlei extends from SW New York through Western Pennsylvania, West Vir- ginia and Virginia into North Carolina (1, 5). The occurrence of P. wehrlei in Letch- er County, Kentucky extends the geo- graphic range of this species NW by 85 km from the nearest reported locality at White Top Mountain, Virginia; this is the first report of this species from the state. Because the shale-rock habitat extends over much of eastern Kentucky it is likely that other populations will be located.

Dense growths of Spirogyra and Mougeotia were present in the marsh and the water temperature and pH were 14 C and 6.3, respective- ly. Microscopic examination of the sample revealed the presence of an infrequently encountered chry- sophycean alga, Chrysamoeba radians Klebs. This alga has been described from various localities in the United States (Prescott, Algae of the Western Great Lakes Area, Wm. C. Brown Co., Dubuque, Ia., 1962; Smith, Bull. Wis. Nat. Hist. Surv. 57:1— 243, 1920; Smith, The Fresh-Water Algae of the United States, McGraw-Hill Co., N.Y., 1950; Tif fany, Contr. Franz Theodore Stone Lab, 6:1-112, 1934; Whitford and Schumacher, A Manual of Fresh- Water Algae, Sparks Press, Raleigh, N.C., 1973), but has not been reported from Kentucky (Dillard, An Annotated Catalog of Kentucky Algae, Ogden Col- lege, Western Kentucky Univ., Bowling Green, Ky., 1974; Dillard and Crider, Trans. Ky. Acad. Sci. 31: 66-72, 1970; Dillard, Moore, and Garrett, Trans. Ky. Acad. Sci. 37:20-25, 1976). The living LBL speci- men was studied for several weeks and a number of photographs and drawings were made. The genus Chrysamoeba (Klebs, Z. Wiss. Zool. 55:353-445, 1893) includes those non-loricate rhi- zopodial chrysophycean algae with a temporary fla- gellate stage in their life cycle, the cells of which do not remain attached by their rhizopodia after di- vision. Several investigators (Doflein, Arch. Protis- tenk. 44:149-213, 1922: Hibberd, Br. Phycol. J. 6: 207-223, 1971; Mack, Ost. Bot. Z. 98:249-279, 1951; Penard, Proc. Acad. Nat. Sci. Philad. 73: 105-168) have provided detailed descriptions of the type species, C. radians. Eight additional species, C. planktonica (Pascher, Ber. Dt. Bot. Ges. 29:523-532, 1911), C. nana, (Scagel and Stein, Can. J. Bot. 39: 1205-1213, 1961), C. pyrenoidifera (Korshikoyv, Arch. Protistenk 95:22-44, 1941), C. tenera (Matvienko, Notul. Syst. Inst. Cryptog. Horti. Bot. Petropol, 7: 10-18, 1951), C. microkonta (Skuja, Nova Acta R. Soc. Scient. Upsal., Ser. IV, 16:1-404, 1956), C. helvetica (Reverdin, Arch. Sci. Phys. Nat., 1:302- 345, 1919), C. extensa (Korshikov, 1941) and C. gelatinosa (Bourrelly, Revue Algol., Mem. Hors. Ser., 1:1-412, 1957), have been described. The last 5 species have been placed in synonymy of C. ra- dians (Hibberd, 1971). Distinguishing characteris- tics of the freshwater species of Chrysamoeba are presented in Table 1. Chrysamoeba radians is distinguished from C. pyrenoidifera by its lack of a noticeable pyrenoid. Hibberd (1971) reported pyrenoids in the organism he identified as C. radians, but they were observ- able only with the electron microscope. In contrast, the pyrenoids of C. pyrenoidifear can be seen with the light microscope. C. planktonica is readily dis- tinguishable from C. radians by its smaller size and from C. pyrenoidifera by its smaller size and ab- sence of a distinct pyrenoid. Hibberd (1971) con- siders Klebs’ (1893) diagnosis of C. radians (Table 1) to be somewhat in error since the drawing ac- companying his description depicts one (not two) chloroplast per cell. This error has been perpetu- ated by Smith (1950), Prescott (1962), and Whitford and Schumacher (1973). The characteristics of the Chrysamoeba collected from LBL corresponded to those presented for C. radians by Hibberd (1971). The naked cells were ovoid (5.0 to 6.6 x 6.0 to 8.2 wm) with several long, thin acicular pseudopodia (Fig. 1). Each cell had a single curved plate-like chloroplast, 2 contractile vacuoles, and a single nucleus. A pyrenoid or stig- ma was not observed. The delicate bifurcate pseu- dopodia arose laterally and several had small gran- ules which were observed moving along them. Asexual reproduction was by cell division with the daughter cells remaining attached for a short time by their pseudopodia (Fig. 2). Although a free swimming flagellate stage was not observed, close microscopic inspection revealed the presence of a short flagellum on the amoeboid stage. Hibberd (1971) observed a second much reduced flagellum in electron microscopic investigations of the alga he identified as C. radians. This vestigial flagellum was not observed with the light microscope. _ Pascher (Die Susswasser-Flora Deutschlands, Osterreichs und der Schweiz, 2, Flagellatae II, 7— TABLE 1.—DISTINGUISHING CHARACTERISTICS OF THE FRESHWATER SPECIES OF Chrysamoeba KLEBS Number of Number of chloro- Pyren contractile Species Cell size (um) plasts oid* vacuoles Reference C. radians 12-15 2 = Dex Klebs (1893) C. radians 4.5-8.5 x 5-12 1 — 2 Lund (1937) C. radians 15-18 1 = 1 Penard (1921) C. radians 6-10 1 — 2 Hibberd (1971) C. planktonica 9-4 1 = 1 Pascher (1911) C. pyrenoidifera 16 1 + 1 Korschikovy (1941) * — indicates absence upon observation of cells with light microscope. 159 Fic. 1.

NOTES 95, 1913) considered the presence of a flagellate stage as requisite for inclusion of rhizopodial forms in Chrysamoeba. He thus erected the genus Rhi- zochrysis for amoeboid forms morphologically sim- ilar to Chrysamoeba but for which a flagellate stage was not observed. He included 3 species in this genus. Two, R. planktonic Pascher (Pascher) and R. scherffelii Pascher, had been described previ- ously as C. planktonic (Pascher 1911) and C. radi- ans (Scherffel, Bot. Ztg. 59:143-158, 1901), respec- tively. The third, R. crassipes, was described by Pascher as a new species. Smith (1920) included a fourth organism, R. limnetica, in this genus. How- ever, Matvienko (Handbook of Freshwater Algae of the U.S.S.R., 3, Chrysophyta, Moscow, 1954) dis- agreed with Pascher’s emphasis on the use of fla- gellar characters in separating Rhizochrysis and Chrysamoeba and combined these genera. Hibberd (1971) noted the difficulty in observing flagella on the amoeboid cells and that these structures are ephemeral in some species. He concluded that presence or absence of flagella should not be used as a sole characteristic for separating these genera. Some taxonomic treatises (Smith 1920, Prescott 1962, Whitford and Schumacher 1973) depict Chrysamoeba with shorter and stouter pseudopodia than Rhizochrysis. However, the observations of C. radians by the author and Hibberd (1971) indicate that the flagellate amoeboid cells have several long, delicate pseudopodia which may be granulate in appearance. The presence of granules was not re- ported in the above mentioned treatises. It there- fore seems that the use of pseudopodial characters in separating these genera is questionable. On the basis of this information, I suggest that there is lit- tle, if any, justification in assigning organisms to Rhizochrysis. Our knowledge of the distribution and life his- tories of chrysophycean algae is limited. Factors which control their occurrence are poorly under- stood and their collection is essentially a matter of chance. Our inability to establish laboratory cul- tures of chrysophycean algae has denied us oppor- tunities to experimentally assess their growth re- quirements and morphological development. Several investigators (Dillard, J. Elisha Mitchell Sci. Soc. 86:128-130, 1970; Hibberd 1971; Nicholls, Phycol. 20:131-137, 1981; Whitford, Phycol. 8:199-200, 1969) have been frustrated in their attempts at col- lection and cultivation of these organisms. Similar problems were encountered in the present study of Chrysamoeba radians. Repeated trips to the LBL marsh failed to yield additional specimens and at- tempts at establishing laboratory cultures of this alga were unsuccessful. Such problems are undoubtedly a major cause of the taxonomic confusion that shrouds chrysophycean algae.

Among the few published records are Stobaera tricarinata Say (Slosson, Ent. News 7:262-265, 1896), Liburniella ornata Stal (Forbes and Hart, Bull. II. Agric. Exp. Sta. 60:397-532, 1900) and Delphacodes puella Van Duzee (Osbom, Ann. Rept. Ohio St. Acad. Sci. 8:65, 1900 according to Metcalf, General Catalogue of Hemiptera, Ed China, 1943). We verified and failed to find any mention of Kentucky in the reports of Forbes and Hart and Osborn. Sperka and Freytag (Trans. Ky. Acad. Sci. 36(3/4):57-62, 1975) reported collecting Delpha- codes spp. including Delphacodes lutulenta (Van Duzee), in connection with the parasitism by mer- mithid nematodes. Delphacids were collected using D-Vac sampler and an insect net in pastures of Fayette and other counties of Kentucky from May to October of 1980 and 1981. The collected specimens were killed and preserved in 75% ethyl alcohol until sorted and identified. Confirmation of many identified speci- mens was made by J. P. Kramer, U.S. National Mu- seum, Washington, D.C. Adult delphacids were found in pastures from the early part of May to the end of October. By early May, the delphacids began reproduction as evi- denced by the presence of nymphs by early June. Delphacodes lutulenta was the most abundant del- phacid in this area (unpublished data). During the 2 collecting seasons, a total of 6 genera and 14 species were collected, including 8 Delphacodes, 1 Liburniella, 1 Sogatella, 1 Euides, 2 Pissonotus and nymphs that looked like Stenocranus. Among these, Delphacodes campestris, D. lateralis, D. mcateei, D. andromeda, D. uhleri, D. montezumae, Sogatel- la kolophon, Euides weedi, Pissonotus flabellatus and P. marginatus are new records for the state. The counties where D. lutulenta and D. campestris were collected are shown in Fig. 1. Other species were collected in Fayette County. Stobaera trica- rinata was collected from Bullitt County. !

Tuomeya and Sirodotia, Freshwater Red Algae New to Kentucky.—The taxonomy, distribution, and ecology of the freshwater red algae of Kentucky are poorly known, as exemplified by the recent addition of 3 red algal genera to Kentucky’s flora (Camburn, Trans. Ky. Acad. Sci. 43:74-79, 1982). The present investigation adds Tuomeya americana (Kutzing) Papenfuss and Sirodotia swecica Kylin sensu Flint to the known flora. Historically, T. americana has been referred to as T. fluviatilis Harvey, and all literature citations herein have used this latter name. Both T. americana and S. suecica are widely dis- tributed in the eastern United States (Flint, Fresh- water Red Algae of North America, Vantage Press, New York, 1970). Few authors, however, have spe- cifically addressed the habitat requirements of these algae. In streams of southern Ontario (Sheath and Hymes, Can. J. Bot. 58: 1295-1318, 1980), S. swecica was a minor component of the epilithic flora in rif fles, while T. americana commonly occurred in rif- fles as well as areas of slower flow. Tuomeya amer- icana was likewise reported to grow in great abundance on rocks in a swiftly flowing stream in Pennsylvania (Webster, Butler Univ. Bot. Stud. 13: 141-159, 1958). Tuomeya americana and S. suecica were collect- ed from the lower reaches of Kinniconick Creek in northeastern Lewis County, Kentucky, on 15-16 September 1982. This high-quality stream is char- acterized by frequent, shallow riffles which have slow to moderate current. Extending upstream from the mouth, 13 aquatic survey stations were estab- lished along a 60 km segment of the stream. Tuo- meya americana and S. suecica occurred at 6 and 1 stations, respectively. Tuomeya americana grew at- tached to cobbles, boulders, and bedrock in shallow riffle areas of slow to moderate current. At some stations, this alga formed profuse growths com- posed of large, dark, linear masses (up to 5.3 em in length) which covered most of the rock surfaces in large areas of the stream. Growth of S. swecica was restricted to a single boulder in an area of moderate current. With these additions, the freshwater red algal genera known from Kentucky are Batrachosper- mum, Chroodactylon (as Asterocystis), Lemanea, Rhodochorton (as Audouinella) (Dillard, An An- notated Catalog of Kentucky Algae, W. Ky. Univ., 163 Bowling Green, Ky., 1974), Boldia, Compsopogon, Thorea (Cambum 1982), Sirodotia, and Tuomeya. The strickly terrestrial red alga Porphyridium was reported from the phytoplankton of Kentucky Res- ervoir (Prather, Kinman, Sisk, Dobroth, and Gordon, Trans. Ky. Acad. Sci. 43:27-42, 1982): however, this habitat suggests a probable misidentification. The apparent rarity of T. americana in Kentucky is probably due in part to its resemblance to aquatic bryophytes, while S. swecica is easily confused with the commonly occurring genus Batrachospermum. Consequently, their rarity may be a function of mis- identification as well as a lack of comprehensive collecting in many regions of the state. I wish to thank Dr. Franklyn D. Ott, Memphis State University, for verifying these specimens and Mr. Melvin L. Warren, Jr. of the Kentucky Nature Preserves Commission for editorial comments.— Keith E. Camburn, Kentucky Nature Preserves Commission, 407 Broadway, Frankfort, Kentucky 40601. Three-Dimensional Modeling of Residual Sur- faces Higher-order polynomial regression equa- tions, in trend-surface analysis, may reflect the vari- ation in particular values with geographic or spatial distributions with more accuracy than lower-order surfaces, but the low-order surfaces may be more useful in isolating important local or regional trends that may exist over larger areas. Thus, surface anal- yses can be considered a process of filtering input signals (measured values or Z-values), where the surface represents the resultant signal after filter- ing. The order of the surface determines the upper limit of variability or frequency of the input data that will pass through the gate or filter. Localized or site-specific variation will be blocked by the filter when lower orders are used, and it will be increas- ingly transmitted as the order of the surface in- creases. This filtering process is in contrast to stan- dard linear interpolation used in contouring, where all the input data are taken in equal importance (Harbough and Merriam, Computer applications in Lene, ily gravity, as viewed from the northwest direction.

However, a vi- sual check on the accuracy of the filtering mecha- nism of trend-surface analysis would be very help- ful in localing sources of noise or localized variation. In addition, visual inspection would be of great val- ue in determining the effectiveness of increasing the order of the regression equations to account for additional variation of the spatially oriented data. A recent study by Henning and Smith (Trans. Ky. Acad. Sci. (abs.) 43 (1-2):92, 1982) dealing with a gravity survey of Early and Middle Precambrian rock units in southwestern Marathon County, central Wisconsin, utilized trend-surface analyses. Bouguer and free-air gravity values collected from 208 sta- tions were analyzed to determine regional trends and sequentially compared with hand-specimen petrology on representative samples of 738 samples collected at approximately 100 sites to determine if an interpretative relationship existed between the gravity anomalies and major lithographic units in the area. However, in determining the effects of increasing the order of the regression equation on local variation and where residuals were occurring, the authors created three-dimensional plots at The University of Akron’s computer center, via an incre- mental drum plotter reading a data matrix from tape. The data matrix was created by using SYMAP and creating a tape file for each residual surface, first through sixth order, for Bouguer and free-air gravity values. The original gravity stations were evenly distributed over the entire study area. Figures 1 through 5 are representative three-di- mensional plots of positive residual surfaces of Bou- guer and free-air gravity values, measured in mil- ligals. All figures are viewed from the NW, 30° from the datum plane. Figures 1 through 5 are the first complete to the fifth-order residual surfaces for Bouguer gravity, respectively. From a brief visual inspection of the various models of the positive residual surfaces (Fig. 1) a definite NW-SE trend of residual values or local- ized noise, not explained by the first degree surface, is illustrated. As one inspects the second residual surface (Fig. 2), the NW-SE trend is still visable, as well as a large residual anomaly in the NE comer of the study area. Figures 3, 4, and 5 illustrate the greater spatial diversity or spread of the noise in the gravity values, as the order of the surface in- creases.—A. D. Smith and R. J.

First Records of Ligumia subrostrata, Toxolasma texasensis, and Uniomerus tetralasmus for Ken- tucky.—The mussel fauna of Kentucky is relatively well-known; however, the lowland areas of the western one-third of the state have only recently been examined for unionid species. Aquatic biota surveys in Ohio River tributaries and the lower Green, Tradewater, and Clarks rivers resulted in the addition of three pelecypod species to the fauna of Kentucky: Ligumia subrostrata, Toxolasma NOTES (=Carunculina) texasensis, and Uniomerus tetra- lasmus. Price (Nautilus 14:75-79, 1900) mentioned L. subrostrata from Kentucky although no locality or drainage was given, and based on Price’s report, Ortmann (Ann. Carnegie Mus. 17:167—189, 1926) speculated that the species may be present in the lower Green River. Ortmann’s speculation was re- cently confirmed upon examination of specimens from a Pond River oxbow in Hopkins Co. (G. J. Fal- lo, pers. comm.). Our specimens were collected in Weirs Creek Swamp (Tradewater River drainage), 13 August 1980, 3.4 km SE of the junction of KY 814 and US. 41A and 6.4 km WSW of Nebo, Hop- kins Co. and West Fork Clarks River (Tennessee River drainage), 4 May 1982, at the Ky 131 crossing, Graves Co. Although these are the first substanti- ated records of the species from Kentucky, its oc- currence is not unexpected since the species is known throughout the Mississippi River drainage north to Wisconsin and South Dakota (Parmalee, III. State Mus. Pop. Sci. Ser. 8:1-108, 1967). The record reported herein for T. texasensis rep- resents the first published locality for Kentucky. Al- though some authors regard T. texasensis as a syn- onym (Johnson, Bull. Mus. Comp. Zool. Harvard Univ. 149:77-189, 1980) or possible form (Parmalee 1967) of T. parva, we follow Stansbery (Ohio State Mus. Zool. Rept. No. 4:1, 1982) in assigning the specific epithet. The species was discovered in Smith Ditch (Tradewater River drainage) on 9 De- cember 1981 at the U.S. 60 crossing in Union Co. Parmalee (1967) characterized the distribution as the southem Mississippi River drainage with the northernmost populations occurring in southern I]- linois. Although Bickel (Sterkiana 28:7-20, 1967) includ- ed U. tetralasmus in a list of Kentucky species based on Simpson (A Descriptive Catalogue of the Naiades, or Pearly Freshwater Mussels: Parts I and II, Bryant Walker, Detroit, Mich., 1900), no published drain- age or locality records are available for the state. The species was collected from the following Ken- tucky localities: Craborchard Creek (Tradewater River drainage), 9 December 1981, at the KY 1340 crossing, Webster Co.; Donaldson Creek (Trade- water River drainage), 10 December 1981, at the KY 293 crossing, Caldwell Co.; Smith Ditch (Trade- water River drainage), 9 December 1981, U.S. 60 crossing, Union Co.; Crane Pond Slough (Green River drainage), 23 July 1980, 3.4 km NE Pleasant Ridge, Daviess Co.; Capertown Swamp (Ohio River drainage), 12 May 1981, 6.3 km SW town of Harrods Creek, Jefferson Co.; Canoe Creek (Ohio River drainage), 10 September 1908, at U.S. 41A crossing, Henderson Co. The records cited herein indicate that U. tetralasmus is widespread in western Ken- tucky and apparently common in the Tradewater River. The species is widely distributed in the Mis- sissippi River drainage (Parmalee 1967). The 3 species noted herein for the first time in Kentucky are all inhabitants of ponds, sloughs, backwaters, and other soft-bottomed lentic environ- ments (Parmalee 1967). Additionally, as noted, they are all widespread in the Mississippi River drainage and have been reported in several surrounding 165 states. Based on the available evidence, the lack of substantiated records for these species is not due to their rarity or limiited distribution but is a result of the neglect of collecting in their preferred habitats. Most pelecypod surveys have focused on the up- land portions of Kentucky’s rivers, and little effort has been directed toward lowland habitats. We feel that these species are more widely distributed and common than our records indicate, and the Ken- tucky range will undoubtedly be expanded as sur- vey efforts focus on the lowland habitats of western Kentucky. Nevertheless, documentation of L. sub- rostrata, T. texasensis, and U. tetralasmus in Ken- tucky further expands our knowledge of the spe- ciose Kentucky fauna and emphasizes the need for additional collecting in poorly known regions of the state.

Comparison of Serum Proteins and Esterases in Three Subspecies of the Bobwhite Quail (Colinus virginianus)—This study was conducted to deter- mine if differences in biochemical characters exist between 3 subspecies of the bobwhite quail: Coli- nus virginianus virginianus, Colinus virginianus, and Colinus virginianus texanus. The presence of significant dissimilarities could possibly support the credibility of the subspecies of this species. A num- ber of avian systematists believe the category of subspecies to be pointless (Dorst, The Life of Birds. Columbia Univ. Press, Vol. 1; 1974) because the subspecies may be synonymous with local popula- tions (Farner and King, Avian Biology. Academic Press, New York, Vol. 1; 1971). Montag and Dahlgren (The Auk 90:318-323, 1973) found esterases, transferrins, and pre-albumins the most likely serum components to show intraspecific variation. This study was, therefore, based upon a qualitative and quantitative comparison of serum proteins (including transferrins and pre-albumins) and serum esterase isozymes. Sibley and Johnsgard (Condor 61:85-95, 1959) es- tablished that individual avian species can be iden- tified by electrophoretic analysis of their sera. Sib- ley (Condor 102:215-284, 1960) obtained valuable taxonomic information at the species level by study- ing avian egg-white proteins using paper electro- phoresis. Transferrins are known to show genetic variation in a wide range of species. Mueller et al. (Genetics 47:1285-1392, 1962) were able to distinguish Co- lumba livia and C. guinea by means of transferrin phenotypes. Baker and Hanson (Comp. Biochem. Physiol. 17:997-1007, 1966) found 3 Branta cana- densis subspecies to have different transferrin phe- notypes than those observed in 4 other subspecies. Quinteros et al.

Baker and Hanson (loc. cit.) found the se- rum albumins of all Branta and Anser geese to be identical in borate gels except for 1 individual. Al- though Baker et al. (Comp. Biochem. Physiol. 17: 467-499, 1965) were able to distinguish Phasianus colchicus from P. versicolor on the basis of serum albumin mobility, they could not differentiate P. colchicus subspecies on the basis of any serum pro- tein. Kristjansson (Genetics 48:1059-1063, 1963) ob- served 2 electrophoretically different pre-albumins in swine. Three pre-albumin phenotypes have been detected in some inbred strains of mice using starch- gel electrophoresis (Shreffler, Genetics 49:629-634, 1964). Baker and Hanson (loc. cit.) found consid- erable individual variation in the pre-albumins of geese. They observed up to 6 pre-albumin bands, but no more than 4 bands occurred in any one in- dividual. Serum esterases show considerable variation in the species that have been studied. Glick (Comp.

Baker and Han- son (1966) found quantitative and qualitative vari- ation in esterase isozymes of geese (Branta and An- ser), but were unable to show any pattern as being species specific. Baker et al. (loc. cit.) also found considerable quantitative and qualitative variation in serum esterases of the ring-necked pheasant, Phasianus colchicus. Serum samples from P. ver- sicolor and subspecies of P. colchicus showed a similar range of esterase variation (9 main regions of activity). Kaminski (Nature 209:723-725, 1966), found 6 active esterase components in the Coturnix quail. The bobwhite subspecies used in this study were obtained from Kentucky and Illinois (C. v. virgini- anus), Florida (C. v. floridanus), and Texas (C. v. texanus). Thirty one-day-old Kentucky bobwhites were obtained from the Game Farm in Frankfort, Kentucky, and were kept in captivity for 1 year. Fif- ty 8-week old Illinois birds were obtained from a game farm at Mt. Vernon, Illinois and were kept in captivity for 11 months. Six adult Florida and 13 adult Texas bobwhites were trapped in their re- spective states and kept in captivity for 6 months. The birds were kept in an isolated room in wire- floored cages, either individually or in groups, at ambient temperature and under natural lighting. The birds were given Purina game bird feed and water ad libidum. Approximately 1 ml of blood was ob- tained from the brachial vein of each bird. The blood was placed in 10 x 75 mm test tubes and allowed to coagulate. Samples were then centrifuged at 2,000 rpm for 10 minutes after which the serum was re- moved and stored at —20° C. Twenty microliter aliquots for total protein and esterase runs were diluted 1:1 with 0.25 M sucrose and refrigerated until electrophoresis. The remain- ing serum was incubated at room temperature for 30 minutes with ferrous ammonium sulfate (0.1 g/ml) for the tranferrin sample, centrifuged, and 20 pl of the supernatant serum were removed and di- luted 1:1 with 0.25 M sucrose. Ten % cyanogum 41 polyacrylamide discs were used for total protein and transferrin separations and 6% discs were used for esterases. Gels were made up with and run in a Tris Borate buffer, pH 8.2. The discs were prerun at 36 mA and 200 volts for 30 minutes before the samples were added. NOTES Twenty microliter aliquots were applied to each disc. Total protein separations were run at 36 mA (3mA per disc) and 200 volts for 4 hours and ester- ases were run at 36 mA and 200 volts for 2 hours. After separation the gel discs were stained for either total proteins, transferrins, or esterase iso- zymes. Total protein gels were stored at 4°C and were kept moist until being scanned by a densitom- eter. The protein pattern generally observed was com- posed of 6 regions: pre-albumin, albumin, alpha,, beta, slow-alpha,, and gamma globulins. Pre-albu- min was the most anodal in migration followed by the other fractions in the above order. The pre-al- bumin portion consisted of the pre-albumin I, mi- grating just in front of the albumin fraction, and a pre-albumin II, migrating faster than pre-albumin I and sometimes separating into 2 bands. The albu- min component separated into 2 fractions with slight differences in migration occurring. The alpha, frac- tion consisted of 2 or 3 faint bands. Beta, the next fraction, separated into 2 to 5 bands. Occasionally, the resolution of these beta bands was difficult due to the high concentration of the beta fraction. Fol- lowing the beta fraction was the slow-alpha, com- ponent which separated into 1 large or 2 smaller bands. No tests were performed to validify the al- pha fractions; they were named on the basis of pro- tein fractions generally observed in polyacrylamide gels (Peacock et al., Science 147:1451-1453, 1965). The gamma fraction was an arbitrary name given to any protein fraction migrating slower than the slow- alpha, band. Each protein fraction was recorded by a densi- tometer as per cent of the total scan. A Student’s t- test was performed on each protein fraction be- tween the 3 subspecies studied. Table 1 gives the means for each protein fraction and indicates which comparisons showed a significant difference. No significant difference was found between any of the protein fractions of C. v. floridanus and C. v. tex- anus. A significant difference was found between the gamma fractions of C. v. virginianus and C. v. floridanus and between the gamma fractions of C. v. virginianus and C. v. texanus. A single classifi- cation analysis of variance with unequal sample sizes (Sokal and Rohlf, Biometry, W. H. Freeman and Company, San Francisco, 1969) was performed to determine if the difference in gamma fractions was due to variation among the subspecies or variation 167 within the subspecies. A significant added variance component was found among the subspecies at P = 0.01. To interpret this added variance, an estimation of variance components in a single classification an- ova with unequal sample sizes was performed. This test showed that 39.17% of the variation occurred among the 3 subspecies and 60.84% within the sub- species. Six main regions of esterase activity were found in the sera of most of the bobwhites studies. Three bands migrated in the albumin region. The other bands migrated in the beta, slow-alpha,, and gamma regions (Fig. 1). Forty six percent of C. v. virgini- anus had a faint alpha, region esterase. This band was not found in the other 2 subspecies. The beta region band was found in members of each subspe- cies studied, but all birds did not have it. A few members of each subspecies showed a fast beta re- gion esterase. Thirty-six % of C. v. virginianus did not show the slow-alpha, but all birds of the 3 sub- species studied had the gamma band. Johnsgard (Grouse and Quails of North America, Univ. Nebraska Press, Lincoln, 1973) suggested southern Mexico as a possible region of origin for the genus Colinus. The early pre-virginianus stock probably moved northward along the Gulf Coast, ultimately reaching the eastern United States where its expansion was limited on the north by cold win- ters and on the west by arid climates and sparse woody vegetation. Although observed electrophoretic patterns showed some variation, no pattern was limited to any 1 subspecies. Different phenotypic patterns were observed in the alpha, and beta regions but it was not within the scope of this study to postulate any specific genetic control. The major esterase phenotypic variation occurred in the albumin re- gion. Baker et al. (loc. cit.) found much of the in- dividual esterase variability in the albumin region of ring necked pheasants. No esterase pattern could be correlated with sex, laying status, or subspecies. The results of this study support the belief of many avian taxonomists that the subspecies category for bobwhite quail is pointless. No significant variation in total protein or esterase electrophoretic patterns was found among the 3 bobwhite subspecies com- pared in this study—D. R. Varney and Rebecca N. Tabatabai, Dept. Biol.

Also, as the official publication of the Academy, news and announce- ments 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, Web- ster’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 numer- als, 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 Indian ink on white paper are acceptable, but should be no larger than 8% x 11 inches. Photographs 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 guidelines 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.

ABSTRACT Gene frequencies were estimated from independent surveys of 223 cats in Warren County and 114 cats in Logan County, Kentucky. Estimated gene frequencies in the combined south-central Kentucky cat population. Based on coefficients of genetic identity, the cats of south-central Kentucky are genetically more similar to populations of southwestern North America than to northeast populations. An hypothesis for this similarity, based on Missis- sippi River trade routes, is proposed. INTRODUCTION Gene frequencies for color, pattern, and length of coat have been reported in world- wide domestic cat populations. Although data have been presented for several North American cat populations, information from much of the south-eastern United States is lacking. To fill this void, surveys were con- ducted from September 1980 through Decem- ber 1981 to ascertain the gene frequencies in domestic cat populations of Warren and Logan Counties in south-central Kentucky. METHODS Phenotypes of cats from Warren and Logan Counties were recorded for free- ranging cats observed by the author. Both phenotype and location were recorded to minimize the likelihood of duplicate record- ings. Mutant alleles considered in these surveys included: sex-linked non-orange vs orange (0+,0); and autosomal agouti vs non- agouti (a*,a); striped vs blotched tabby (t*, tb); 1Present address: U.S. Fish and Wildlife Service, Ken- tucky Research Station, 334 15th Street, Bowling Green, Kentucky 42101 intense vs dilute pigmentation (d*,d); white spotting vs non-spotted (S,S*); dominant white vs. pigmented (W,W*); Siamese dilu- tion vs non-Siamese (cS,c*); and short vs long hair (L*L). Nomenclature follows that of the Committee on Standardized Genetic Nomen- clature for Cats (3). Robinson (9, 10) detailed the modes of inheritance and interaction of these alleles. Recessive allelic frequencies (q) were cal- culated as the square root of the observed phenotype frequencies. Dominant allelic frequencies (P) were calculated as 1-q. Stan- dard errors were obtained as_ 1-q?/4N and (2-P)P/4N for recessive and dominantalleles, respectively. Sex ratios were determined by maximum likelihood estimates (11). Con- formity to the Hardy-Weinberg Equilibrium was determined by chi-square comparison of observed and expected phenotypes of sex-linked orange. Gene frequencies between the Warren and Logan County cat popula- tions of other North American cities was determined by calculating coefficients of genetic identity (8), based on 5 loci (0, a, t, d, and W) as employed by Anderson and Jen- kins (1). 2 TRANS.

(A coefficient of 1.00 indicates genetically identical populations.) GENE FREQUENCIES IN CATS— Twedt lations have been summarized by Gerdes (6), Fagen (5), Morrill and Todd (7), and Ander- son and Jenkins (1). Coefficients of genetic identity between the cat population of south- central Kentucky and the cat populations of other North American cities (Fig. 1), indicate the south-central Kentucky cat population appears to be shifted from the ‘Anglo’ cat population of eastern North America and has a greater genetic similarity to the ‘Spa- nish/Mexican’ cat population of western North America as identified by Todd et al. (12). Possible explanations for the deviation of the Phoenix and Vera Cruz cat popula- tions from other ‘Spanish/ Mexican’ popula- tions are offered by Todd et al. (12). The high degree of similarity between this Kentucky cat population and the ‘Spanish/- Mexican cat populations of Texas and other western cities is unexpected based on Ken- tucky immigration patterns. Several south- central Kentucky communities were first established around 1780 with increased European immigration beginning shortly thereafter (4). By 1800 the human population of the two counties had grown to over 10,000 (2). The population more than doubled dur- ing the next 10 years and by 1810 was over 24,000 (14). (Political boundaries have not remained consistent since original counties were established.) The majority of these immigrants, originating in the former Brit- ish colonies of Virginia, Maryland, and the Carolinas, entered Kentucky via the Cum- berland Pass with additional immigrants moving down the Ohio River from Penn- sylvania. Between 1785 and 1795 Mississippi River trade between Kentucky and the territories of New Spain was at its zenith. Additionally, the colonization schemes of Spain in the central Mississippi River Valley culminated during these years (4). These activities, coin- ciding with the initial pre-1800 settlement of south-central Kentucky, may have provided ‘Spanish/ Mexican’ cats, which in turn pro- duced sufficient offspring to resist the influ- ence of ‘Anglo’ cats arriving with the later post-1800 influx of ‘Anglo’ immigrants. These hypothetical cats of ‘Spanish/Mexican’ lin- eage could account for the high degree of genetic identity between the cat population of south-central Kentucky and the cat popu- lations of Texas and other western cities. Estimated gene frequencies in cat popula- tions of Tennessee, Arkansas, Mississippi, and Louisana are needed to further eluci- date this hypothesis. ACKNOWLEDGEMENTS I thank E.

SMITH Coal Mining Administration, College of Business Eastern Kentucky University, Richmond, Kentucky 40475 RICHARD T. WILSON Department of Geology, Eastern Kentucky University ABSTRACT Mine roof support and resupport systems in coal mines are the leading element of expense in ground control. Selected parameters associated with support systems were collected in 5 coal mines, located in Pike, Martin, and Floyd Counties, eastern Kentucky, to aid in determining the degree of relationship among support and resupport systems on the occurence and distribution of mine roof falls. A total of 250 falls were measured that involved 4 coal seams: Peach Orchard, Brods, Pond Creek, and Fire Clay. Results illustrate the vast majority of falls occured either in the entry or intersection, had spans of approximately 20 feet, portrayed some presence of water before the actual fall, occured in less than 30 weeks after initial coal extraction, usually were located more than 100 feet from the nearest coal face, gave evidence of cracks in mine roof before occurrence of the fall, generally presented a stable roof profile before the fall, showed presence of sloughing of coal ribs, and exhibited little or no evidence of floor heave. Most roofs were either originally supported by mechanical anchor bolts (57.2%) or resin bolts (38.8%); very rarely did the roof fail if supported by posts or cribs. The results of 7 research hypotheses testing the relationship of the type of initial mine roof support system and selected physical parameters illustrated that only 2 hypotheses were statistically significant. In general, the shorter the time between coal excavation and the mine roof fall, the greater the frequency of full column or resin roof bolts were in use. Also, sloughing of the coal ribs were associated with a greater occurence of resin roof bolts. INTRODUCTION Roof fall occurrence is a common ground control problem. In fact, roof falls are so common many mining operatings consider them a part of the regularly computed downtime (1, 2). In some instances, it may cost as much to clean up a fall as it does to mine actual coal. The loss of revenues asso- ciated with downtime is not the only tragedy involved; there is sometimes a loss of life. Roof falls are the major cause of death in underground coal mines in the United States, accounting for over 50 percent of all fatali- ties (2). Nearly all roof failures can be traced to 2 major causes: 1 the interaction of stresses in the roof, pillars and floor exceeded the rupture point of the roofrock strata; and 2 geological disturbances in the immediate roof, such as slickslides, channel sands, transition zones, rider coal seams, kettle- bottoms, cracks and joints, and the pres- ence of water, are often associated with roof falls (3,4,5,6). As Coal is excavated, stresses are set up in the mine roof because the equilibrium of the in-situ stress state is upset, resulting in pressures that cause fractures and slight movements that are frequently difficult to detect. Unless the immediate roofin the exca- vated area is given support by artificial means, an increasing probability of a roof fall or a succession of falls, highly variable in size, exists. The two broad types of roof support systems involve the artificial sup- port of the immediate roof above the coal and the main roof. In general, artificial sup- port for mining purposes is only concerned with the immediate roof, since large blocks of solid coal or pillars will support the main roof. SUPPORT SYSTEMS If the immediate roof is made of inter- bedded material, laterally continuous and void of irregularities, it can be supported (3). The most widely used method of support- ing underground entries is the roof bolt (1,7). Roof bolts have been found to have some INFLUENCE OF SUPPORT SYSTEMS IN MINES—Smith E advantages over other types of roof sup- ports, such as timbers, posts, or cribs. Pro- duction has increased and fatalities have decreased since the introduction of roof bolts in the 1950's (7). Most estimates place the current roof bolt consumption at slightly over 100 million per year. At an in-place cost of approximately $10 per bolt; this repres- ents an annual effort of over $1 billion. Of all the roof bolts installed, mechanically an- chored bolts account for about three- quarters of all the bolts. However, in spite of such extensive use of rock bolts, the mecha- nism by which bolts provide support is not completely understood. Each year a large number of injuries are caused by bolt fail- ures at the rib and roof areas. Maintaining adequate tension in the bolts adds substan- tially to the competence of the roof strata by the mechanisms of suspension, friction, and keying (8,9). Peng (1) documents the existence of a high correlation between roof fall fatalities and questionable roof support practices. In addition, roof-bolt length often determines the height of the fall by holding more roof strata together and causing it to fall as a single unit (5). Peng (1) suggested that roof bolts do not adequately perform under the following conditions: 1 the bolts are too short to anchor in a suitable horizon and thus permit excessive bleedoff of bolt ten- sion; 2 the bolts do not adequately torque during installation; 3 the bolts are not rou- tinely checked for bleedoff; 4 the roof falls at or above the anchorage horizon. The blasting of coal or rock places high stresses on the roof strata and can adversely affect roof bolts in the strata (10). Blasting has been linked to the loss of bolt tension, the breaking and bending of bolts, and cracks in the roof causing the roof rock to lose its ability to support a load, thus initiat- ing roof falls. Vibrations caused by machinery associated with mining may also lead to roof bolt fail- ures. These vibrations are transmitted into the bolt anchorages by the operation of transportation systems in the immediate area of the roof bolts. RESUPPORT SYSTEMS Most roof falls are not cleaned up and resupported because resupporting these roof falls often exposes men and equipment to dangerous unsupported roofs. Inspec- tion of roof fall statistics by Sterns, et al. (11) indicate that 5 per cent of all roof fall fatali- ties occurred during resupport operations. The process is also very expensive and unless it is a vital entry, such as a beltway, haulage, or aircourse, it is abandoned (11,12). Supports made of cribbing or beams in some Cases are not effective protection due to the shrinkage of timbers, thus losing con- tact with the rock. Conventional methods of rehabilitating mine roofs include: 1 drive a bypass around the fall (this has a low initial cost but can lower production by reducing haulage speeds and causing the rerouting of tracks and belts); 2 cribbing of the fall by the use of posts, cribbs, steel beams or headers. Re- support by this method reduces production by narrowing passages and therefore slow- ing haulage speeds (12). An alternative to standard roof resupport is the steel arch canopy. This method has been proven effec- tive in minimizing exposure of miners to dangerous roof resupport work. However, canopies are often prohibitively expensive. METHODS Cooperation by 4 mining companies, located in Pike, Martin, and Floyd Counties, allowed the investigation and data collec- tion of mine roof falls in 5 different coal mines (Fig. 1) to aid in the determination of the influence of support/resupport systems on the occurrence and distribution of roof falls in eastern Kentucky. A total of 250 falls were measured and involved 4 coal seams: Peach Orchard, Broas, Pond Creek, and Fire Clay. Multiple linear regression analysis techniques (13) were performed, via SPSS (Statistical Package for the Social Sciences) and DPLINEAR (Double Precision Linear Regression), to test hypotheses relating type of support before the fall (coded either resin or nonresin for discriminative analysis pur- poses) with selected physical parameters.

Specifically, the variables collected and analyzed concerning type of support before and after the fall, length of bolts before and after the fall, and descriptions of the original support and resupport systems. Associated parameters that are related to support systems and their design that were also studied included: location of the fall, mine roof span, presence of water before the fall, time of roof fall after coal excavation, distance to the nearest coal face, presence of cracks before the fall, assumed condition of the roof before the fall, sloughing of coal ribs before the fall, and presence of floor heave condition before the fall.

An F-test was utilized to test for significant relationships among types of support before the fall and seleced physical parameters. The assigned alpha level of 0.05 tor two tailed, nondirectional test was considered statistically significant. However, the employment of a correction for multiple comparisons was necessary, using the Newman and Fry(14) method. The corrected alpha level of 0.007 was used before any specific research hypothesis was considered significant “approaching significance at the 0.05 level The power for each specific research hypothesis, using a medium effect size is 0.995. As evident from an inspection of Table 1, the vast majority of falls occurred either in the entry (40.4%) or intersection (34.4%), had spans of approximately 20 feet (81.2%), por- trayed some presence of water before the actual fall (78.0%), occurred in less than 30 weeks after initial coal excavation (71.3%), were located usually greater than 100 feet from the nearest coal face (70.4%), gave evi- dence of cracks in mine roof before occur- rence of fall (75.2%), generally portrayed a good roof condition before the fall (60.8%), showed presence of sloughing of coal ribs (48.8%), and no occurrence of floor heave (88.0% no heaving) before occurrence of fall. In terms of the characteristics of the original support by mechanical-anchor bolts (57.2%) or resin or full-column bolts (38.8%); very rarely did the roof fail if supported by posts (0.4%) or cribs (1.2%). The roof-bolt spacing is usually associated with 4-foot centers in the vast majority of the cases studied, both before and after the fall, which is standard engineering practice in eastern Kentucky coal mines. The length of roof bolts do appear to be longer in resupported roof sys- tems than used in the initial roof support system (92.5% of initial support systems used 60 inch bolts or less as compared to 44.3% of the resupported mine roofs).

In general, the shorter the time tiple comparison using the Newman and_ between coal excavation and roof fall, the Fry (14) method of adjusting the decision greater the frequency of full column or resin criterion. The parameters of times of roof fall roof bolts were in use. Since resin bolts are after initial coal excavation and presence of generally used in roof rock that is in poor sloughing of the coal ribs or sides before the condition or a suitable anchor horizon is 12 not available, the presence of the bolts appear to shorten the length of time between coal excavation and the roof fall occurrence. Possibly, the individual roof layers in the immediate roof are already weakened and near failure, hence failure occurs relatively quickly after coal excavation, which pro- vided the initial support. In addition, slough- ing of the coal ribs were associated with a greater occurrence of resin roof bolts. This may indicate that the resin support systems hold the immediate roof bed as a thicker or more rigid unit, thus allowing for greater stress concentrations to occur along the coal ribs. If the stress concentrations exceed the allowable rupture strength of the coal, then failure and eventual sloughing of the ribs will develop. EXCELLENT GOOD Fic.6 Distribution of assumed condition of mine roof before occurrence of the actual roof fall (excellent, very good, good, poor, very poor). TRANS. KENTUCKY ACADEMY OF SCIENCE 45(1-2) The parameters of cracks in roof before the fall, distance to the nearest face, pres- ence of water before the fall, assumed con- dition of the mine roof before the fall, and presence of floor heaves before the fall were not found to be statistically related to the type of original mine support systems. Hence, these factors are not directly influ- enced by or on the initial support system. CONCLUSIONS The last decade has shown considerable advancement in the knowledge of improved roof control systems and the prediction of potential problem areas. Advances in satel- lite imagery analysis of linears and their correlation with “bad top” or mine roof-fall areas, improved pillar design, barrier blocks, and mine projections, utilization of differ- ential movement station via extensonme- ters to monitor separations in roof layers, and utilizations of the bore scope and T.V. camera to monitor the mine roofas the min- ing aproaches suspected problem areas are all techniques that are important and should be standard mining practice in ground con- trol. However, as illustrated in this study, a detailed analysis of selected factors asso- ciated with mine roof support and resup- port systems, based on historical record of falls, can give important correlations that may be useful in forecasting potential prob- lem areas that are under the immediate control of the ground control supervisor, engineer, or shift foreman.

Department of Zoology, Southern Iilinois University at Carbondale, Illinois 62901, and Department of Invertebrate Zoology, Smithsonian Institution, Washington, D. C. 20560 ABSTRACT Recent collections in western Kentucky have added 5 crayfishes, Cambarellus puer, Fallicambarus fodiens, Orconectes lancifer, O. palmeri, and Procambarus viaeviridis, to the faunal list of the state, and several new localities are reported for Cambarellus shufeldtii. Five of the 6 species (F. fodiens being the exception) are limited in geographic occurrence to the Jackson Purchase region; all are in need of conservation status evaluations by the Endangered Species Committee of the Kentucky Academy of Science. INTRODUCTION Nearly 40 years ago, Rhoades (1) presented the first comprehensive report on the cray- fishes of Kentucky. He visited each of the 120 counties in the state and reported the pres- ence therein of 27 species and subspecies. Since that time, several of Rhoades’ subspe- cies have been elevated to specific rank (2), new species have been described or reported from Kentucky (3, 4, 5), and the presence of 1 species in the western part of the state has been discovered as a result of additional collecting (6). Recently, extensive field work, particularly in western Kentucky waters, has revealed the presence of 5 previously unreported species of crayfishes. Several new distributional records for Cambarellus shufeldtii (Faxon 1884), a species previously known from only one locality in Kentucky (6), were also discovered. It is the purpose of this paper to report records of 6 crayfishes, all of which have limited ranges in Ken- tucky, so that knowledgeable evaluations of their conservation status may be made by the Endangered Species Committee of the Kentucky Academy of Science. ACCOUNT OF SPECIES Distributional records are based mostly on recent collections made in western Ken- tucky and on those deposited in the Illinois Natural History Survey (INHS), the US. National Museum of Natural History (NMNH), and Southern Illinois University at Carbon- dale (SIUC). 14 Species accounts include the locality, major drainage, county, date of collection, and (in parentheses) the museum in which specimens are deposited, their sex, and reproductive condition. The abbreviation “T’ designates form I or first form males; “II” form II or second form males; ‘“j’, juveniles; and ‘ovig.”, ovigerous females. Genera and species are treated alphabetically. For syn- onymy and statements concerning the ranges of each, see Hobbs (2). Cambarellus puer Hobbs 1945 — New Kentucky locality: (1) unnamed cypress swamp (Mayfield Cr. dr.) 4.0 km. E Melber at Hwy. 1241 crossing, Graves-McCracken Co. line, 29 September 1979 (NMNH 664 II, 89, 1j3, 1jQ); 17 November 1979 (NMNH 241, 19); 22 December 1979 (NMNH 261, 1@1I, 19); 15 January 1980 (NMNH 1@lII, 29); 22 February 1980 (NMNH 161, 481, 69). REMARKS—This crayfish ranges from Bra- zos and Brasorio counties, Texas to the Mis- sissippi River basin in which it occurs from the lower delta to Johnson County, Illinois. Despite considerable collecting efforts in presumably suitable habitats throughout much of western Kentucky, Cambarellus puer has been found in only 1 locality. Most of the localities sampled, all of which appeared to provide suitable ecological con- ditions, yielded C. shufeldtii, a species con- sidered by Penn and Fitzpatrick (7) to be dominant to C. puer. The 2 species rarely coexist, at least for long periods of time, and C. shufeldtii was reported (7) to have sup- planted C. puer in several localities farther ADDITIONS TO CRAYFISH FAUNA— Burr and Hobbs 15 south. Crayfishes associated with C. puer at the swamp adjacent to Mayfield Creek were Cambarus diogenes subsp. and Procamba- rus acutus acutus (Girard 1852). Page and Burr (6) reported the occurrence of Cambarellus puerin southern Illinois and southeastern Missouri. The locality cited here is the first for Kentucky and helps to fill the distributional gap between southern Illinois and western Tennessee. Because of its limited occurrence in Kentucky, we recom- mend that C. puer be considered by the Endangered Species Committee for Special Concern or Threatened status.

(7) Bayou du Chien (Mississippi R. dr.) at Hick- man; county road 3.4 river km. from River, Fulton Co., 15 June 1973 (NMNH, 461], 39). Remarks—Page and Burr (6) reported the only previous record of Cambarellus shu- feldtii from Kentucky (Mitchell Lake, 1 km. W Oscar, Ballard County), and predicted that this species would be found in other oxbow lakes. It has been found only in lowland sloughs, lakes, and oxbows, usually around bald cypress knees in association with sub- mergent vegetation and organic debris. Cray- fishes associated with C. shufeldtii were Cambarus diogenes subsp., Orconectes lan- cifer(Hagen 1870), Procambarus acutus acu- tus, and P. clarkii (Girard 1852). The status of the species was listed as undetermined by Branson et al. (8) because insufficient information was available to permit an assessment of its occurrence within the state. Although its range is limited to the extreme western counties, it is more widespread in Kentucky than previously thought. In veiw of the newrecords reported here, we recommend that Cambarellus shu- feldtii be reassigned to the status of Special Concern. Fallicambarus fodiens (Cottle 1863)—New Kentucky localities: (1) W.

The R? term is an indication of the amount of variance explained or accounted for by the regres- sion equation describing the actual depth to bedrock distribution. Thus, for the first degree surface, only 2.02 percent of the var- iance in the geographically distributed bed- rock depth was accounted for by the surface. When this R? was tested over random varia- tion, which has an R? equal 0.0, this was not found to be significant. The 1 vs. 2 term in the table makes use of the full versus res- tricted model concept. For example if the first model, Z = Bo + B1X; + BoY; + €;, where Bo is equal to the constant term, 8; and B» are the regression coefficients, and X and Y are the geographic coordinates of each of the 138 borehole locations in the study area, € is the error or residual vector, and Z is depth to bedrock at each location, is termed the full model, then the restricted model is the full model with the null hypothesis being true.

KENTUCKY ACADEMY OF SCIENCE 45(1-2) the first degree trend over random variation, B, and B2 would be equal to zero, hence there would be no first order regression. In model comparisons, the restricted model would contain only the regression weights of the next lower degree surface, since the null hypothesis would assign a value of zero to the higher order regression coefficients. As illustrated in the table, assuming a 2- tailed, nondirectional test with an alpha level set at 0.05, the second through the sixth order trend surfaces were found to be Statistically significant in predicting depth to bedrock over random variations. In the model comparisons process, the second order surface accounted for more explained variance than the first. Since as shown in Fig. 9 and 10, the positive residual values and their locations were similar, they were not found to be statistically significant. Fol- lowing the model comparison process, the sixth order surface was found to be statisti- cally better fit than the fifth. However, as shown in Fig. 13, the magnitude of the residuals are located accurately, larger errors will be made in predicting depth to bedrock for this high order polynomial surface. ——— 2 FSLSSSS Sess: 2 = SSosees iy DATA RANGE DEPTH VARIATIONS (FT) ness DEPTH TO BEDROCK IN FEET FROM THE SURFACE OF BOREHOLE (GTH DEGREE RESIQUALS) Fic. 13.—Residual surface of sixth degree polynomial trend of depth to bedrock from surface of borehole.

SUMMARY The computer mapping of the contour, polynomial trends, and residuals can be a valuable aid in using trend surface analysis as a potential tool for predictive analysis. As illustrated in this paper, a visual inspection of the trends, residuals and their magni- tudes seem to indicate the second or third order surfaces as being the best fitted poly- nomial surface. However, by using a F-test and the full and restricted model concept, the sixth order surface was found to be sta- tistically the best fit. The R?s values are inflated because of degrees of freedom in the numerator due to added terms in the full model, which might explain why the sixth order polynomial trend was found to 29 be significant. The use of plotting the surfa- ces can give the investigator a chance to actually visualize what the trend surface looks like and locate the residuals and their magnitudes. This process can bring in the investigators’ “common sense’ and geolog- ical judgement into play to determine the best fit. With the increasing use and availa- bility of appropriate software and hardware, computer modeling should be used in con- junction with statistical models in estimat- ing the usefulness and limitations of trend surface analysis for predictive purposes.

This represents a contribution towards the completion of a floral and faunal inventory of the Jessamine Creek Gorge, a natural area that has recently come under the management of the Kentucky Nature Conservancy. A total of 1,555 individuals, represent- ing 26 species, were collected. Although the creek has a history of pollution, this study indicates that no substantial alteration of the fish fauna has occurred. INTRODUCTION In 1982, the Kentucky chapter of the Nature Conservancy entered into agree- ments with landowners in the Jessamine Creek Gorge area to protect and preserve what is considered one of the most ecologi- cally significant natural areas in the state. A stewardship committee was formed to develop an inventory of the flora and fauna of the gorge area. Because of the relative inacces- sability of the gorge, the terrestrial flora and fauna are considered to be minimally im- pacted. There has been much concern, however, that pollution, in the form of efflu- ents from sewage treatment plants serving the towns of Wilmore and Nicholasville as well as from other sources, may have altered the community composition of the stream ichthyofauna eliminating many sensitive species. This report presents the results ofa survey of fish populations in Jessamine Creek and its major tributary, Town Fork. STUDY AREA Jessamine Creek and Town Fork originate from springs in north-central Jessamine County and course through a deep and lar- gely inaccessible valley in southwest Jes- samine County to empty into the palisades section of the Kentucky River. The stream bed is fairly typical of central Kentucky streams with a substrate of bedrock, limes- tone slab, and coarse rubble. The upper reaches of the stream are characterized by riffle and shallow pool areas flowing through croplands and pasture. Near the town of Wilmore, the creek descends into a steep gorge that is part of the palisades. Here, short stretches of riffles separate pools that may be hundreds of meters long and several -meters deep. Most of the gorge is densely canopied by a riparian forest. The Nicholas- ville sewage treatment plant is located on Town Fork which empties into Jessamine Creek above the gorge while the Wilmore sewage treatment plant is located ona small tributary that empties into Jessamine Creek at the head of the gorge. MATERIALS AND METHODS Sampling was conducted at several sites from June, 1983 to August, 1983: 1. Jessamine Creek at KSR 29 overpass, 2.6 km from Nicholasville. 2. Jessamine Creek at Glass Mill Road overpass, 3.3 km West of Wilmore (sampled twice) 3. Jessamine Creek crossing at Camp- ground Lane, 3.3 km West of Wilmore. 4. Town Fork at Shun Pike bridge, 6 km West of Wilmore 5. Jessamine Creek Gorge, 0.5 km stretch of stream approximately 2.5 km down- stream from Site 5. Fish were collected using standard elec- troshocking and seining techniques. At road- way overpass sites, the length of stream sampled was approximately 150 m. Over one km of stream within the gorge was sampled (sites 5, 6, 7). Fish were identified to species, counted, maximum and minimum sizes recorded, and returned to the stream. Those species that were unidentifiable in the field were preserved in 10% buffered formalin and saved. 30 FISHES OF JESSAMINE CREEK— Barton RESULTS AND DISCUSSION A total of 1,555 individuals, comprising 26 species, were collected during the course of this study (Table 1). Among the most abund- ant species were the minnows Campostoma anomalum, Pimephales notatus, and Semoti- lus atromaculatus (30.5%, 14.8%, and 4.1%, respectively). The blacknose dace, Rhinich- thys atratulus, was the most abundant spe- cies at the Town Fork site (8.2%). The large numbers of smallmouth bass (Micropterus 31 dolomieui) recorded were mostly juveniles in the 25 to 45 mm size range. The most abundant darter was the rainbow darter (Etheostoma caeruleum), which was re- corded at all sampling stations, while the closely related orangethroat darter (E. spec- tabile) was restricted to headwater sites. According to Clay (1), E. spectabile generally occurs in smaller streams than E. caeru- leum and two species rarely overlap in distribution.

KENTUCKY ACADEMY OF SCIENCE 45(1-2) not be expected to be present in streams of the Kentucky drainage (1, 3, 4). Five species recorded in this study, the fathead minnow (Pimephales promelas), the black bullhead (Ictalurus melas), the yellow bullhead (I. natalis), the mosquitofish (Gambusia affinis), and the orangethroat darter (Etheostoma spectabile) were not reported by Howell (2). When the results of this study are compared with other studies on central Kentucky stream fishes (4, 5), Jessamine Creek appears to be fairly typical of a small to medium sized stream of moderate gradient with respect to the diversity of the fish popula- tion. Although no sampling was attempted near the mouth of the creek, additional spe- cies characteristic of larger rivers probably are present there. None of the endangered, threatened or rare species reported by Branson et al. (6) were recorded. Compari- son of the total number of species recovered in this study with the species diversity reported fora polluted creek in central Ken- tucky (7) suggests that the pollution that affects Jessamine Creek is not sufficient to have caused a substantial change in the fish population. More detailed analysis of the age structure of these populations is needed before this can be verified. In summary, comparison of the species list compiled in this study with that com- piled by Howell (2) and his students sug- gests that no major changes have occurred in the fish populations in the last 15 years. The area of Jessamine Creek Gorge to be managed by the Nature Conservancy sup- ports a relatively diverse and seemingly healthy fish population that has not been severly impacted by pollution in the water- shed.

PASS Department of Entomology, University of Kentucky Lexington, Kentucky 40546-0091. ABSTRACT Developmental rates for the potato leafhopper /Empoasca fabae (Harris)] were determined at 2 constant temperatures, 24°C and 27°C. Seven kinds of leguminous host plants were used: ‘Apollo’, ‘Buffalo’, and ‘Riley’ alfalfa; ‘Major’ broad bean; ‘Kenstar’ and ‘Kuhn’ red clover; and ‘Williams’ soybean. Development of the leafhopper varied among hosts. The least time was required to develop from egg to adult emergence on broad bean; the leafhoppers developed at the rates of 5.08% and 6.0% per day at 24°C and 27°C, respectively. A relatively slow rate of development was attained by potato leafhoppers on soybean (4.44% and 5.39% per day at 24°C and 27°C, respec- tively). Males developed faster than females in most cases. INTRODUCTION The potato leafhopper, Empoasca fabae (Harris), is a polyphagous insect which is commonly found on alfalfa, clover, soybean, and many other cultivated and wild plants in Kentucky. Broad bean (Vicia faba L.) is a plant on which the potato leafhopper is easily reared. Consequently, much informa- tion on the potato leafhopper has been compiled using broad bean as the host. However, broad bean is not commonly grown in the areas where this insect is a pest. Simonet and Pienkowski (1) (using broad bean as the host) and Kouskolekas and Decker (2) (using ‘Buffalo’ alfalfa as the host) reported different threshold temperatures for nymphal development of the potato leafhopper. Saxena et al. (3), working with other species of leafhoppers, reported that host plants can influence the developmen- tal rate of leafhoppers. It is imperative that the biology of the potato leafhopper be understood in order to devise sound management strategies for this pest. The study reported herein tested for influence of host plant on the develop- ment of the potato leafhopper. MATERIALS AND METHODS Seven kinds of greenhouse-grown, legum- inous host plants were used for develop- mental studies: ‘Apollo’, ‘Buffalo’ and ‘Riley’ alfalfa; ‘Major’ broad bean; ‘Kenstar’ and ‘Kuhn’ red clover (the former a pubescent variety and the latter a variety with a few closely-appressed hairs); and ‘Williams’ soy- bean. Alfalfa and red clover plants were cut and allowed to regrow 1.5 to 2 weeks (to a height of 10 to 15 cm) prior to being used in this study. Broad bean plants ca. 15 cm tall and soybean plants at growth stages V2 through V3 (4) were selected to start the experiment. Two environmental chambers were maintained at a 15:9 L:D photoperiod and at 24 + 2°C and 27 + 2°C, mean tempera- tures which the potato leafhopper frequently encounters in its natural environment. Illumination was by high output, cool white, 40 watt fluorescent lamps. The host plants were caged with 61 cm x 15.2 cm diameter plexiglas tubing, the de- tailed design of which was described by Simmons (5), and placed in the environmen- tal chambers in a randomized block design, 2 blocks/chamber. There were 5 such repli- cates at each temperature. Relative humid- ity varied from 60% to 99%, depending on the temperature and when the plants were watered. Plants were watered from the bot- tom as needed. Insects were collected from an alafalfa field in Fayette Co., KY, with a sweep net. The contents were emptied into a 30 x30 x40 cm plexiglas cage, which had a sleeve opening (covered with stockinnette) which permit- ted hand entry. The leafhopppers could eas- ily be sexed without magnification as they rested on the sides of the transparent cage. Adult female potato leafhoppers were aspi- rated from the cage into a 65 ml cup, the lid 33 34 TRANS. KENTUCKY ACADEMY OF SCIENCE 45(1-2) of which had a 2 cm diameter opening; an alfalfa stem was placed in each cup and a piece of cotton was inserted into the open- ing after aspirating the leafhoppers. Ten females were collected per cup, one cup being used for each host plant. During hot weather the cups of leafhoppers were placed in an ice chest until they were trans- ported to the laboratory. Female potato leafhoppers were allowed to oviposit over a 12 hour period of continu- ous light. The amount of time required by the potato leafhopper to develop from egg to adult emergence at 24°C and 27°C on each host plant was recorded. The first day was counted as 12 hours after the oviposition period ended. Adults which emerged on each day were removed from the cage, sexed, and the number of each gender recorded for each host plant. Duncan's Multiple Range Test was used to separate the mean developmental rates of the leafhoppers among host plants. Treat- ment (host plant) means were compared within temperatures (24°C and 27°C) for the sexes combined, as well as for males and females separately. RESULTS AND DISCUSSION The number of days required for the potato leafhopper to develop from egg to the adult stage on 7 leguminous hosts at 24°C and at 27°C is presented in Table 1. The number of days required for the potato leaf- hopper to develop at 24°C ranged, among the plants tested, from 19.8 days (19.4 for males and 20.1 for females) on broad bean to 22.7 days (22.4 for males and 22.9 for females) on soybean. A similar duration (ca. 19.0 days) for newly oviposited eggs to reach the adult stage on broad bean at 24°C can be calcu- lated from a study by Simonet and Pien- kowski (1). At 27°C the duration in days for development ranged from 16.7 days (16.5 for males and 17.4 for females) on broad bean to 18.7 (18.1 for males and 19.2 for females) on soybean.

The fastest development was on the broad bean at 27°C; one of the 2 fastest rates at 24°C also occurred on the broad bean. The mean per cent develop- ment per day on broad bean was 5.08 (5.17 for males and 5.0 for females) at 24°C; at 27°C the rate was 6.0%/day (6.07%/day for males and 5.85%/day for females). In the order of decreasing rate of development on the other host plants, the trend was as follows: alfalfa, red clover, and soybean. Among the 3 alfalfa varieties, the potato leafhopper developed at the fastest rate on ‘Buffalo’ at 24°C, but there were no differences among alfalfa var- ieties at 27°C. Between the 2 red clover varie- ties, the fastest rate was on Kuhnat 24°C, but no significant difference in developmental rates was observed between red clover var- ieties at 27°C. Development of the potato leafhopper on soybean was the slowest of all plants tested at 24°C and one of the 2 slow- est at 27°C. At 24°C on soybean, the devel- opmental rate was 4.44%/day (4.5%/day for males and 4.38%/day for females), and at 27°C the developmental rate was 5.39%/day (5.54%/day for males and 5.24% day for females). Male potato leafhoppers developed faster than females (Tables 2 and 3). This was true for development at both temperature regimes and on all plants tested, with 2 DEVELOPMENT OF POTATO LEAFHOPPER— Simmons, et.al. TABLE 2.

Newton and Barnes (6) also noted that female potato leafhoppers required longer than males to develop. The sex ratio of all adults which emerged was 51:49, male to female (49:51 at 24°C and 52:48 at 27°C). The results reported herein indicate that host plants can influence the developmen- tal rate of the potato leafhopper. This sug- gests that some of the earlier data obtained on the biology of the potato leafhopper using 35 broad bean as a host plant may not be directly applicable to other host-plant sys- tems. For example, if one utilized develop- mental data obtained from potato leaf- hoppers reared on the broad bean to predict phenological events occurring on soybeans, those events would occur later than pre- dicted. On the other hand, those same data should provide accurate predictions of development on ‘Buffalo’ alfalfa, a variety commonly grown in Kentucky. ACKNOWLEDGEMENTS The authors thank Dr. R. E.

SMITH Coal Mining Administration, College of Business, Eastern Kentucky University, Richmond, KY 40475 JAMES C. COBB Kentucky Geological Survey, University of Kentucky, Lexington, KY 40506 Kort F. UNRUG Department of Mining Engineering, University of Kentucky, Lexington, KY 40506 ABSTRACT A computer-based information system for engineering and geological data pertaining to surface mining was developed under the Title III Program by the Kentucky Geological Survey and the University of Kentucky Mining Engineering Department. Approximately 1,000 tests were performed on cores derived from the Eastern Kentucky Coal Field using slake durability, direct shear, Brazilian tensile, punch shear, and ultimate and compressive strength testing. Statistical analyses were performed on the data generated by this project. Multiple linear regression, hypothesis testing, power analysis, stepwise regression, and model building were the statistical methods applied to the Title III data base. The analyses provided estimates of relationships between the sets of engineering test results and the geological criteria in the overburden rocks. Statistically significant relationships were found among the parameters: slake durability, direct shear-test mean and standard deviation, punch shear-stress mean and deviation, Brazilian tensile-test mean and standard deviation, and the criterion gross- overburden lithology. No predictive relationships with the various engineering and geological tests were found associated with depth of core sampling. behavior of overburden rocks. Data of this type are usually incomplete and scattered INTRODUCTION There are at least 36 types of rocks in the coal-bearing strata of Kentucky that can be differentiated by geologic characteristics. All these rocks occur in the highwalls and spoils of surface mines. Each rock type was deposited as sediment under different con- ditions and responds differently to weather- ing and compaction, particularly after dis- turbances such as mining. Asa result, each rock will weather at a different rate, produce water with different pH, and remain stable after backfilling at varying slope angles. There is, unfortunately, no source of infor- mation which contains data on the weath- erability and strength of these rocks from which mining and reclamation planning can be based. However, with the introduction of state and federal legislation governing reclama- tion procedures for surface-mined lands, immediate needs were checked for defining geological characteristics and engineering throughout various agencies, reports, and private sources. The acquisition of these data for use by all public and private parties will lend support in particular to Sec. 515 (3) of Public Law 95-87: To restore to approximate original contour, the operator, ata minimum shall backfill, grade, and compact (where advisable) using all available overburden and other spoil and waste materials to attain the lowest practicable grade but not more than the angle of repose. Provided adequate data are available for geological and engineering classification of the overburden, groupings ofrocks could be introduced which would serve as an aid to more effective and efficient backfilling of the overburden. Additionally, the technical feasibility of mining coal at a particular loca- tion and the durability and safety of a pro- posed excavation, whether in a strip under- ground mine, cannot be assessed adequately without comprehensive data on the engineer- 36 ANALYSIS OF SELECTED ROCK STRENGTHS— Smith, et.al. 37 ing characteristics of the rock units which confine and support the coal strata to be removed. The design of the slopes and other reclamation procedures, applications of ex- cavating equipment, blasting patterns, and haul roads in a surface mine or the size openings and selection of mining methods in an underground mine are governed by the types of rock encountered. Only by ob- taining comprehensive information on the properties of the rocks, both geological and engineering, can the most effective and economical design be attained. The principal goal of this project was to develop a computer-based information sys- tem for geotechnical data related to surface mining and reclamation. Other objectives were: (1) to generate data on the geological and engineering properties of overburden rocks, (2) to create computer programs to access and analyze this data, (3) to perform statistical analyses on the data generated, (4) to direct theses projects in diverse aspects of geology and engineering related to over- burden rocks, and (5) to develop a user's manual for the computer information sys- tem. The thrust of this paper is to report the results of statistical analysis on the data initially generated from this project. METHODS Location of Cores Used for Testing In order to make the study of overburden characteristics relevant to Kentucky’s coal- producing areas, drill cores were sought from many sources. Government agencies and private companies were contacted for drill cores or coal-bearing sequences in which typical overburden rocks were en- countered. These cores were geologically described, sampled, and prepared for phys- ical testing. The geological description was done using the 3-digit code system of Ferm and Weisenfluh (1). This system was selected for use because it is the method recom- mended by the Kentucky Bureau of Surface- Mining Reclamation and Enforcement and it facilitates computer storage of geologic data. In addition, the names applied to the rock types are a combination of driller and geologists’ terms. As noted by Farm and Weisenfluh (op. cit.), the cores logged by their methods should alert engineers to rock types which can produce problems in slope and shaft construction, and general planning for underground and surface mines. The classification employes a three-digit system instead of the traditional descriptive classification. The first digit, ranging from one to nine, describes the rock type by grain size. The second digit may describe either the sand components, color, or fossil con- tent. The third place digit describes any sed- imentary features present. Other descrip- tive symbols, suchas the term ‘flat’ (FLT) or “rippled” (RIP) may follow the description if shale or sandstone streaks are present. If the streaks are horizontal and parallel, the term “flat” is used; and ifthe streaks are wavy, the term ‘rippled’ is used. Table 1is a summary of the three-digit rock classification, and accompanying geological description of the overburden rock types found in the cores studied. Table 2 shows the core locations, recorded by computer identification num- ber, Carter coordinates, geological quad- rangle, county, surface elevation, and cored interval of the cores used in the present study.

BRAZILIAN TENSILE TEST: 1. Objective: This test is used for the determination of the tensile strength of rocks. 2. Procedure: The Brazilian Test is an indirect method of determining the tensile strength of rocks. This test involves a solid circular disc witha length to diameter ratio of 1:1. The disc is loaded diametrically (line or strip load) until failure. This test is only valid when primary fracture initiates from the center of the disc spreading along the loading diameter. 3. Application: The data from Brazilian test along with the data from the Uniaxial Com- pression test will give the limits of min- imum and maximum strength of the rock. This information can be used for the mechanical winning of minerals in rock, drilling and blasting of rock, and failure predictions of roofs and floors in under- ground mines. PUNCH SHEAR AND DIRECT SHEAR: 1. Objec- tive: These tests are used to determine the shear strength of rocks parallel and per- pendicular to bedding planes. 2. Procedure: The punch-shear test involves a flat disc of rock cut parallel to bedding. The thickness of the disc may range from 0.25 to 0.50 inches. The shearing effect is achieved by loading a cylindrical plunger perpendicular TRANS. KENTUCKY ACADEMY OF SCIENCE 45(1-2) to bedding until the plunger punches through the disc (i.e., failure occurs). The direct-shear test uses a shear box that has two movable parts. The specimen is placed in the shear box and is set in hydrostone to prevent movement. The lower half of the shear box remains stationary while the upper halfis loaded until sliding movement initiates across the lower half. Thus, failure is achieved when the sample breaks parallel to bedding. 3. Application: The application of the direct shear and punch shear data is used for the calculations of sliding and fail- ure of a high wall in strip mining. Since the data is determined parallel and perpendic- ular to bedding, a limit of shear strength of the high wall can be determined for high- wall stability. UNIAXIAL AND ULTIMATE COMPRESSIVE STRENGTH, POISSON'S RATIO, AND YOUNG'S MODULUS: 1. Objective: The objective of this test is to determine the Compressive Strength, Poisson's ratio, and Young’s Modu- lus of a rock sample. 2. Procedure: A cylin- drical, right-angled specimen of rock with a length-to-diameter ratio of 2:1 is uniaxially loaded between the platens of a testing machine. The displacement of the original dimensions caused by uniaxial loading is measured by linear variable differential trans- ducers (LVDI). This displacement of dimen- sions is used in the calculation of a stress- strain curve of the sample. From this curve the Poisson's strength of the sample is found at the failure point of the curve for the sample. 3. Application: The data obtained from the test is used for the basic calcula- tions of elastic theory and can be related to the angle of internal friction. This in turn can be used for the design of high walls and foundation work in strip mining and refill work, respectively. SLAKE DURABILITY: 1. Objective: This test is used for the determination of weather dur- ability ofrock. 2. Procedure: The Slake Dura- bility test uses 10 pieces of a sample weigh- ing 40 to 60 grams each. These samples are placed in a wire-mesh basket which is immersed in water. The basket is rotated at 60 rpm for 30 minutes. Later, the basket is oven dried for 24 hours to remove all excess water and weighed. The Slake Durability ANALYSIS OF SELECTED ROCK STRENGTHS— Smith, et.al. Ba Index is calculated as a percentage of final weight to initial weight of the sample. The Slake-Durability Index ranged from 0 to 100%. The 0% represents total disintegration of the sample. 3. Application: The Slake Dur- ability Index gives the weathering durability of the rock sample. It also gives the percen- tage of matrix material produced during the handling of the spoil material and can be related to fill calculations. RESEARCH QUESTIONS The major research questions asked in the present study are: 1. Are there predictive relationships among the various engineer- ing tests and basic lithologies? 2. Can each specific rock type according to the system of Ferm and Weisenfluh (1) be descriminated from the remaining rock types based on the results of the engineering-rock testing? STATISTICAL TECHNIQUES MULTIPLE LINEAR REGRESSION AND HYPOTHESIS TESTING— Multiple linear regression is an extremely flexible technique that makes available much statistical information once certain mechanical topics are mastered. Newman (2) and Fraas and Newman (3), in a discussion of the advantages of regression hypotheses testing procedures, compiled several reasons why multiple linear regres- sion is an appropriate and, in many Cases, preferable procedure. A few advantages are: 1. Multiple linear regression is the general case of the least sum of squares solution. Chi square, t-and F-tests are special cases of the least squares solution. Therefore, any- time anyone could use any of the special cases of the least squares solution, the more general case would be appropriate, 2. With the regression procedure one states the hypothesis and then writes the regression model to test the hypothesis. So every test of significance is a test of a specific hypothesis, 3. Regression is more flexible in being able to write the models that specifically reflect the research hypotheses, 4. Since regression can deal with categorical and continuous variables, it is more flexible in its ability to reflect real world problems, 5. All analyses of covariance procedures are really regression procedures because the covariables are always held constant by regressing it on the criterion. MODEL BUILDING—Applied researchers who use multiple regression frequently are in- terested in: 1. Estimating the relationship between a set of predictive variables to a criterion in a sample for the purpose of gen- eralizing to the population; 2. Estimating the magnitude of relationships from sample to sample and then to the population. Gen- erally, in any regression model, a R? needs to be large enough to be practically as well as statistically significant. This means that the regression model or equation should actu- ally be able to predict significantly better than by chance alone as well as visual inspection, especially in the case of rock mechanics studies. If the model does not predict significantly better, then the model is not practically useful and one must reconsider the variables that went into the model. The following are some reasons that may be considered in explaining why the model may not be predicting well: 1. The variables used in the model should be con- sidered as interactions. However, there could be first, second, third, and higher orders of interactions, which increases the number of variables examined in the model. As more interactions are added, the number of vari- ables decreases, thus causing a greater instability in the regression equation’s abil- ity to accurately predict, 2. There may be second or higher degree curvilinear rela- tionships between the criterion and predic- tor variables that are not reflected in the model. Therefore, in multiple linear regres- sion, if curvilinear relationship exists, the linear predictor is not a good predictor since the model does not reflect the curvili- near aspect. One can examine by plotting the error vector or residuals to see if a regu- lar second or higher order pattern exists, hence reflecting a possible curvilinear rela- tionship. Unfortunately, everytime a higher order term is added to the model the number of variables increase, thus reducing the data collected to variable ratio, 3. Other important considerations include the relia- bility and validity estimates of the variables. Even though a particular variable has been demonstrated in the literature as an impor- aD TRANS. KENTUCKY ACADEMY OF SCIENCE 45(1-2) tant factor, the current estimates, limited by present data collection and instrumenta- tion techniques, of the variable may be poor and better estimates should be sought before it is included in the model. Obviously, the model will only be as good as the degree of relevancy of the variables entered into the model. Once the variables in the model are deter- mined to be a good predictor and have prac- tical significance, usually determined by hypothesis testing and model comparisons, interpretation of the regression weights and associated values for the variables are another major concern. Each variable in the model has a partial regression weight by which it is multiplied. These weights are calculated by the least sum of squares method via a commercial computer pro- gram like SPSS or SAS, and are intended to maximize the prediction. Generally, the larger the R? term the more accurate the prediction. However, a common problem with this procedure is that researchers and readers of research tend to interpret the partial regression weights and the standard- ized regression weights by attaching greater importance to those variables with higher weights. This is only legitimate if the varia- bles are not significantly correlated, or there is no multicolinearity. The more the correla- tion between the predictor variables, and hence multicolinearity, the less appropriate it is to interpret these weights. RESULTS Overburden Rock Testing Almost 1,000 individual tests were per- formed on cores, using slake durability, direct shear, punch shear, Brazilian tensile, compressive, and ultimate compressive strength. Whenever possible, 3 samples were used in the testing process, with a recorded mean and standard deviation for the strength test. A total of 262 different rock samples with partially paired data were recorded and used in the statistical analysis of the results to answer the major research ques- tions generated in this study.

However, a correction for multiple comparisons was deemed necessary in a number of cases in the hypothesis-testing process. The alpha level was corrected using the Newman and Fry (4) method. The corrected alpha level was used before each specific hypothesis was considered statistically significant. Listed below are the corrected alpha levels for the affected hypotheses. The symbols S denotes statistical significance, while NS denotes nonsignificance at the stated alpha level Acorrected alpha level is equal to 0.025 Ss corrected alpha level is equal to 0.010 rock groups: sandstones (pebbly and sand- stones and conglomerates), sandy shales and fireclays, shales and fireclays, ironstone, limestones, and flint clays. Hence, the coding of 500 to 900 represents relatively coarse- grained rocks of sandstones, pebbly sand- stones, and conglomerates. The coding of 090 to 299 illustrates the basic lithology of shales and fireclays coupled with ironstone, limestone, and flint clay; while the coding of 000 to 039 represents coal and bone. As illus- trated in the coding scheme, increasing sig- nificance is granted to coarser-grained rock and the reverse is true for finer-grained rock. By this grouping, all the rock samples (N=262) can be entered into the regression equa- 41 tions for predictive purposes and allow for sufficient power of the test for internal valid- ity purposes. Table 4 is a summary of the models tested, both full and restricted models, R? for both models, degrees of freedom-numerator, degrees of freedom- denominator, F-ratio, probability levels, and statistical significance for each research hypothesis that tested for discriminative relationships among the engineering and geological parameters and the criterion var- iable, gross lithology. The second general research question was approached by coding all the other classification numbers as a 2, and the actual classification number as a 1. This allowed for the formulation of a dichotomized criter- ion variable to be used for discriminative analysis purposes. The dependent and engi- neering and geological parameters were entered into multiple linear regression equa- tions. The results of this testing, for illustra- tive purposes, are summarized in Tables 5 through 7. However, due to the general lack of success of this procedure, not all possible combinations of classification numbers were delineated in this manner. Table 8 is a summary table illustrating the results of the hypotheses testing and model comparisons using depth to the top of the sample core as the criterion.

Two primaparous individuals were fou nd tobe age 18 * while two multiparas were 23+. An additional 38 females were examined according to established skeletal criteria for age and maternal status. Among the total number, 17 women between the ages of 15-20 were classified as nulliparous/primaparous, two multiparous and one questionable. In the age group 21 and over, 8 were nulliparous/primaparous, 9 multiparous, and one questionable. Based on the lowest possible skeletal age, the mean age at first pregnancy was found to be 16.6 years. Based on the highest possible skeletal age, the mean figure was 19.7 years. INTRODUCTION Investigation of the maternal status of females in the age range 15-30 by means of established skeletal criteria strongly sug- gests that age at first pregnancy at the Indian Knoll site was between 16 and 19 years. The shell midden site was occupied for more thana millennium, between 3352 * 300 to 2013 t 350 according to C'* readings taken from antler points, but these figures are based on Libby's (1) unrefined half-life for C'* and are certainly inaccurate. More recent adjustments in the half-life of the trace element as well as in dating methods have been put forward by Derricourt (2) with respect to Egyptian material. While population density at any given time must have been very limited at Indian Knoll, Snow's (3) estimate of twenty-five concurrent inhabitants undoubtedly is too low. He based his calculations on two erroneous hypotheses, that the site was continuously occupied throughout the year and that the principal staple foodstuff was mussels, a marginal nutritional source which would not have supported a large popula- tion (3). The general health status of the Indian Knoll people as attested by skeletal remains suggests that a more varied and healthier diet was available. METHODS Four cases of archaeologically attested pregnancy or childbirth related deaths are used here as an index to maternal status ofan 51 additional 38 females in the age ranger 15-30 years to determine the earliest probable age at first pregnancy. More than 4 deaths from obstetric causes must have occurred, but only those which are clearly defined archae- ologically are taken into account here. Among males at Indian Knoll, slightly more than 50% died between the ages of 15-30 as opposed to slightly more than 60% of females. Differences in life expectancy, however, can- not be attributed wholly to birth trauma (4). All statistics are based on 836 individuals currently housed at the Museum of Anthro- pology, University of Kentucky. The individuals in the comparative group were selected on the basis of skeletal age and good condition of the remains. No indi- vidual with skeletal pathologies owing to systemic disease was included. Criteria for maternal status for all 43 females are sum- marized in Table 1. Skeletal age is based on standard criteria: 1. condition of the public symphysis; 2. epiphyseal union and ossifi- cation; 3. suture closure ectocranially and where possible, endocranially; 4. absence/- presence of third molars. Maternal status is based on the following criteria: 1. condition of the pubic symphysis; 2. ventral lipping of the os pubis. 3. dorsal pitting of the os pubis; 4.absence/presence of tubercles; 5. absence/ presence of auricular grooves. None of these criteria is wholly reliable. Auricular grooves, for example, may occur in females presenting no other skeletal signs of childbirth or even in males (5). The condi- 52 TRANS.

Multiparous status is considered to have existed only in the pres- ence of definitive scarring of the pubic sym- physis and at least one other criterion or, in some instances, in the presence of 3 of the criteria if symphyseal wear cannot be tho- roughly assessed. Burial #340 represents one of the two teenage females. Epiphyseal union had occurred in all long bones, but the epiphy- seal scars are strongly marked. The iliac crests are not fused. Both maxillary and mandibular molars were in the process of erupting at the time of death. An approxi- mate age a few months either side of 18 is AGE AT FIRST PREGNANCY AT INDIAN KNOLL—Finkenstaedt reasonable. The pubic symphysis, the most important skeletal evidence in this case, is immature and completely undamaged. Slight dorsal pitting of the os pubis as well as slight bilat- eral auricular grooves of Houghton’s (5) GL type are present. Houghton (5) does not regard either as indicative of mechanical stress. The young woman was buried in a flexed position on the abdomen while remains of the fetus buried with her are described in the burial records as being beneath her pel- vic cavity. Fetal remains are fragmentary. Only one measurement is possible, that of both tibiae which measure identically 5.8 cm. The proximal tibial epiphyses cannot be identified in the incomplete remains. These would not be present, however, if fetal age were less than nine intra-uterine months (6). An approximate calculation of fetal lengthis 44.25 cm based on Smith's reduction table cited by Krogman (6). These figures indicate that the fetus was not simply buried with the adult but in fact was unborn. One can conclude only that the individual died in consequence of her first pregnancy. No sig- nificant pathologies can be identified in the skeletal remains to account for this event. Case 2 According to analysis of fetal remains, a second individual, burial #240, apparently died as a result of premature childbirth. Burial was in a shallow pit without grave goods. The adult was placed in a tightly flexed position on the abdomen. The re- mains of a fetus in middle to late intra- uterine life were found beneath the left foot of the mother in a context which apparently had been disturbed in antiquity. The fetal femur measures 5.4 cm and the tibia 4.9 cm; thus the fetus was roughly 36-37 cm in length. The young woman was 18 or 19 at the time of death. The distal humeri show tra- ces of epiphyseal fusion while the distal fib- ula is fused but the epiphyseal line is visible on the posterior aspect. Neither the iliac crests nor the ischial rami are fused. The billowing, completely undamaged symphyseal surfaces of the os pubisindicate 53 that the individual was experiencing her first pregnancy. Slight dorsal pitting is pres- ent but would not necessarily suggest a pre- vious birth episode (7). Very slightly ventral lipping on the os pubis is present, and a deep auricular groove on the right innomi- nate contrasts with a much smaller groove on the left. Non-symmetrical or even unilat- eral appearance of auricular grooves is not uncommon in this population. The pres- ence of these 3 traits would indicate a mul- tipara were it not for the totally undamaged pubic symphysis. Case 3 An interesting anomaly is offered by #146, the burial of a woman who died in child- birth as the direct result of the malpresenta- tion of a full-term infant. The infant had become inextricably wedged in the birth canal. The excavation photographs are un- clear on this point, but according to the archaeologist’s notes, both arms and one leg had been born and were to have been fol- lowed by a cervical certebra. This extraordi- nary complication must indicate a fatal anencephaly in the infant. The right femur of the infant measures 7.5 cm. and the tibiae 6.4 cm. for an over-all length of about 47-50 cm., not too small for full term in this gracile population. The age of the mother must have been 22-23. All cranial sutures are two- thirds closed ectocranially. The third molars are present and slightly worn. All epiphyses are fused except for the medial ends of the clavicles. The left pubic symphysis was retrieved, and the ventral demi-face is worn while the dorsal half retains some billowing of the surface. Ventral lipping and dorsal pitting are present, but the minimal auricu- lar grooves are Houghton’s GL, a type men- tioned above as characteristic of nulliparas and males in whom auricular grooves occur. The question arises whether one can deter- mine that symphyseal wear is the result of repeated childbirth or simply of chronolog- ical age. While it is not unlikely that the individual had experienced a previous birth episode, there is little difference between the condition of her pubic symphysis and those of males in the same age group. Thus one may speculate that the number of preg- 54 TRANS. KENTUCKY ACADEMY OF SCIENCE 45(1-2) nancies in this case was small. Case 4 Burial #242 is that of a woman about 25 years of age whose death is attributable to childbirth as a primary cause. The burial records attest that fetal bones were found in the pelvis. The fetal remains cannot be located now, and the fetal age is unknown. The woman was buried in a pit barely large enough to contain the body, and, and at that, the limbs must have been bound in tight flexion. Age may be estimated from a number of skeletal criteria. The basilar suture is closed, as are the iliac crests, the ischial rami, and the epiphyses of all long bones. All third molars had erupted with the exception of 1 M3. The pubic symphyses show a strong ventral rampart and considerable resorp- tion and granulation of both demi-faces. The ventral margins are very worn and flat- tened, features which may be ascribed to repeated birth episodes. Marked dorsal pit- ting is present. A deep auricular groove occurs on the right innominate with a lesser groove on the left. The individual may be regarded as multiparous. DISCUSSION Among these 4 individuals, the earliest age at pregnancy was about 18, while the 2 multiparas were over 20. Thirty-eight addi- tional females, selected as stated above, also were examined. None attests skeletal evi- dence for childbirth before about age 17 at the earliest. It is entirely possible that early death among females at Indian Knoll is attributable to birth trauma associated with first pregnancy. Therefore, the nulliparous/ primaparous group must be treated as a single unit since in either case skeletal evi- dence of birth trauma would not necessarily be present. Among the N-P group of 27 females, the mean age at pregnancy was 19.7 years based on the latest age derived from skeletal crite- ria. The earliest possible mean age was 16.6. Both are included here to allow for inevita- ble variations in reading the same data, since no criterion for aging prehistoric remains is entirely reliable. That skeletal evidence does not attest signs of a birth episode in any individual before age 17 but does suggest nulliparous or primaparous status in individuals in their twenties in- dicates that age at first pregnancy was rela- tively late at the Indian Knoll site. Moreover, the very limited index offered by the known maternal deaths is seen to represent an accurate view of maternal status at this site. LITERATURE CITED 1. Libby, W. F. 1955. Radiocarbon Dating.

Department of Biological Sciences Eastern Kentucky University Richmond, Kentucky 40475 and Northeastern Forest Experiment Station U. S. Forest Service, Berea, Kentucky 40403 ABSTRACT Analyses of physio-chemical, piscine and macrobenthological data secured from two small-stream drainages affected by surface mining in eastern Kentucky are presented. Adverse pH values were not encountered during the study. Stream magnesium, calcium, manganese and sulfate concentrations increased rapidly during the onset of mining and continued to increase until 1982. The bottom sediments in both streams have remained very heavy throughout the study. The creek chub, Semotilus atromaculatus, has greatly increased its populations in the headwaters while populations of other piscine species have remained virtually unchanged. Although active mining has ceased in the Leatherwood Creek drainage, fish population recovery has been minimal. A few species have been successful in re-establishing small populations, but many species are still absent. A second impulse of mining started in 1979 in Bear Branch probably resulted in a setback of recovery in that stream. None of the macrobenthological data have been published previously. Analysis of these data demonstrated a decrease in the total taxa and mean diversity of Leatherwood Creek and Bear Branch from June 1968 to October 1970 followed by a modest increase in these 2 features from October 1970 to July 1982. The population levelin most taxa remains low and mollusca have been extirpated in both streams. Mean diversity indices may be misleading, principally because of habitat changes that allow groups of organisms like the Heteroptera to replace other groups. INTRODUCTION To evaluate the impact of surface mining on the fish faunas of first and second order streams in east-central Kentucky, Branson and Batch (1) conducted a 17-month study from 1967 through 1969. The study area is located in Breathitt County, Kentucky and includes Leatherwood Creek and Bear Branch. Six stations were established on each stream (Fig. 1). The principal aim of the study was to document the effects of surface mining activities on benthos and fish fauna. Another objective was to trace changes in stream chemistry. Settleable solids were considered to be one of the most important features relating to changes in fish and re aa aa benthos. Fic. 1.

These ‘Hydrologist, U. S. Forest Service, Berea, Kentucky 40403. data, and new information gleaned during 55 56 the present study, are presented here. A follow-up study, conducted during 1972, indicated no tendency toward recovery by the fish fauna (2). In fact, further degradation and elimination of species had occurred. With many of the competing species gone, the creek chub population expanded, a phenomenon observed also in Tennessee (3). The mining history of this area and streams, including normal and mining- induced chemical and physical features, were discussed and analyzed by Bryan and Hewlett (4), Curtis (5, 6, 7), and Dyer and Curtis (8). In the interim, several other studies with direct bearing on the problem of coal min- ing and the environment have appeared, particularly with reference to benthic orga- nisms. Because of their limited mobility, benthic organisms may be better indicators of mine pollution than fishes (9). Increased sedimentation not only degrades habitat for fishes, particularly during increased water temperatures (10), but it also often severely alters or eliminates benthic organisms depen- dent upon a clean-gravel habitat. Sediments often fill the interstices of gravel to depths of one meter or more, replacing a cobble- gravel habitat with a silty sand one (11). In the case of the streams we studied, the silt load during active mining was observed to reach 46,400 ppm (5). Highest yields of sedi- ment from surface mining normally comes during the first 6 months after mining (7). Sedimentation poses direct problems for benthic organisms (12). It has been known that insect drift downstream is the major means ofrecolonization ofboth natural and altered streams (13); upstream migration of insects being only 5-30% as important in repopulating a decimated area (14). Chang- ing the bottom from a cobble-gravel habitat to a sandy one, however, may preclude active recolonization by upstream migra- tion in larval insects such as stoneflies like Pteronarcys and Acroneuria because of the unstable sand. By contrast, caddisflies with heavy cases (Dicosmoecus) are more suc- cessful in moving upstream on sand (15). Such phenomena can produce unbalanced benthic faunas by allowing resistant forms TRANS. KENTUCKY ACADEMY OF SCIENCE 45(1-2) to control a given habitat. The objectives of this study were to col- lect data on fish populations and benthos invertebrates to compare with data collected in the original studies made in 1967-1969, and to trace changes in water chemistry following surface mining and reclamation activities. MATERIALS AND METHODS As in the previous studies, the fish popu- lations at each station were sampled by 30 minutes of intensive seining. During all sampling visitation, invertebrates were hand- collected from representative, random sec- tions at each sampling site, care being exer- cised to include all habitat conditions. Mean diversity ‘'d” indices were calcu- lated using the machine formula method of Lloyd, Zar and Karr (16) see also, Weber (17), an index that is compared with a hypothe- tical maximum “‘d” based upon arbitrarily selected distributions (18) related to MacAr- thur’s (19) broken-stick model. This model results in a distribution frequently encoun- tered in nature (17), i-e., a few abundant spe- cies and a progressively large number of species that are less abundant. Since in nature the members of a given local com- munity are highly unlikely to be equally abundant, Lloyd and Ghelardi(20) proposed the concept of “equitability’ “e” and pres- ented a table for its determination (17) using a number of species in a sample ‘'s’ with the number of species expected “'s’” from a community that conforms to MacArthur's (19) model: e = —. Our calculations of ‘e” follow these authors’ recommendations. The physio-chemical measurements were made by standard methods in the laborato- ries of the Northeastern Forest Experiment Station, USDA, Forest Service, Berea, Ken- tucky. Samples were collected at monthly intervals. RESULTS Water Quality Determinations of water quality have been made since late 1967 in Leatherwood Creek and since the spring of 1968 in Bear Branch (5). Although many individual substances SMALL STREAM RECOVERY— Branson and elements were monitored by the North- eastern Forest Experiment Station at Berea, Kentucky, we are reporting the results only for the substances that readily indicate the influence of surface mining on water quality or substances that may be implicated as partially responsible for the perturbation of biotic communities.

SPECIES DIVERSITY In contrast to species richness, changes in species diversity values were less pronounced. Species diversity ranged from 2.0-3.0 (x = 2.3 + 0.3) in 1971 Salt River collections, and 2.2—3.2 (x = 2.7 + 0.5) in 1979 Salt River collections (Fig. 2). In 1971, the peak in species diversity values occurred in mid-July, with lowest diversi- ty found in June. However, in 1979, diversity estimates were highest in early June and much lower in mid-July. These peaks are related to the phenology and population size of selected species in the community. a 7 30 Se Ee ot WS ] < AS hisses aii 7 Fs aa SN BE eee Pas Van ee / = =| = 20 ~ ese d ac w > a o—1971 Salt River © -01979 Salt River SPECIES ©— 1979 Brasheor's Ck 2 oo+ - ~ + 1 - : . JUNE COLLECTION JULY DATES Figure 2: Comparison of species diversity in 1971 and 1979 from the Salt River and in 1979 from Brashears Creek adult caddisfly collections. For example, in 1971, early June collections contained large numbers of Hydroptila perdita, Cheumatopsyche pettiti, and Ceraclea cancellata, which raised redundancy and lowered diversity to 2.0 (Fig. 2). Mid-July collec- tions showed highest diversity values (3.0) which reflected peak emergence of the majority of the species and a decline in numbers of C. cancellata. Diversity remained relatively con- stant through July and did not decrease until | early August when Protoptila maculata became | more abundant and most other species declined in numbers. In 1979, early June collections from the Salt displayed highest diversity, with an estimated value of 3.1 (Fig. 2). Diversity values from mid-June to mid-July were lower, ranging from 2.2 to 2.4. During this period, Cheumato- psyche campyla comprised 45 to 55% of each hour’s catch. Ceraclea cancellata was abundant in mid-June (19% of total catch), but was sur- passed in numbers by H. perdita and P. maculata (emerging earlier than in 1971) in July. During most of July, these two species con- tributed 25 to 50% of each hour’s collection and along with C. campyla, they constituted approx- 105 imately 80% of each hour-long collection. The end of July brought a return to the higher diver- sity values seen earlier in the season. Numbers of C. campyla, P. maculata, and H. perdita decreased, along with the total number of individuals collected. POPULATIONS In terms of numbers of species present in 1979, the family Hydroptilidae was highest with 17 species; collections in 1971 contained 14 species. Although 45% of all caddisflies collected in 1971 were hydroptilids, only 15% were of this family in 1979. This decrease is due primarily to a reduced mid-July emergence in the number of Hydroptila armata. This species had only a brief emergence peak in 1971 (4). Since the sample collected on 28 May 1979, contained a very large number of H. armata, we believe that this species did not substantially decline in numbers from 1971 to 1979, but simply emerged earlier in 1979. The second most abundant hydroptilid in the Salt River in 1979 was Neotrichia vibrans, a species not found in the 1971 Salt River collections. The family Leptoceridae had the second highest species richness with 16 species in the Salt River 1979 collections; the 1971 samples had 15 species. Species of the genus Ceraclea were numerically dominant in both 1971 and 1979. Within this genus, some changes in relative abundance of individual species did oc- cur. Ceraclea tarsipunctata increased markedly in abundance, from 0.05% of all leptocerids in 1971 to 9.0% in Salt River 1979 collections. Although the sponge populations declined dramatically, abundance of adults of the sponge-feeding caddisfly, C. transversa, were similar in 1971 and 1979 (0.2%). Changes also occurred within the leptocerid genus Triaenodes. Triaenodes melaca and T. tarda were both present in 1971 collections but were completely absent in 1979 collections. In the family Hydropsychidae, we found 9 species in both 1971 and 1979. Numerical dominance of this family is attributable to the very high numbers of C. pettiti and C. campyla collected, although the relative proportions of these 2 species changed dramatically. In 1971, the ratio of C. pettiti to C. campyla was 2:1, whereas, in 1979, the ratio was 9:1. Examination of the various families of net spinners reveals other changes in their relative abundance between 1971 and 1979. Most notable was a shift in the ratio of Hydro- psychidae to Philopotomidae, which was less than 2:1 in 1971 collections, but increased to more than 229:1 in 1979 collections. The ratio of Hydropsychidae to Polycentropodidae also in- creased from 4:1 in 1971 to 75:1 in 1979. 106 Trans.

The caddisfly fauna of the Salt River and Brashears Creek in 1979 shared 41 species in common; 3 were present only in the Salt River and 3 were present only in Brashears Creek (Table 1). In most cases these unique species were represented by only 1 or 2 in- dividuals, with the exception of Cheumato- psyche pasella which was represented by 33 individuals in the Salt River. Species diversity estimates in Brashears Creek (range = 1.9—3.3, X = 2.4 + 0.7), were slightly lower than those of the Salt River, although the pattern of these estimates showed the same general trend (Fig. 2). Diversity values were approximately 3.0 in early June but fell in late June to about 2.0 due to the numerical dominance of C. campyla, H. perdita, and P. maculata. The lowest diversity value of the season, 1.9, occurred when P. maculata and H. perdita comprised 58% and 19%, respectively, of the sample. Diversity values again rose at the end of July and returned to approximately 3.2, as total catch declined in numbers. Individuals of the caddisfly family Hydro- ptilidae were more common in Brashears Creek (36% of all individuals collected) than in the Salt River (15%), and N. vibrans was also abundant in Brashears Creek collections. As in the Salt River, 15 species of leptocerid caddisflies occur- red in Brashears Creek, making it the second highest family in species richness. Examination of the net-spinning species in Brashears Creek in 1979 shows that the ratio of C. pettiti: C. campyla was 6:1 Hydropsychidae: Philopotamidae was 71:1, and Hydropsychidae: Polycentropodidae was 75:1. Although each of these ratios was higher than 1971 Salt River col- lections, they were lower than 1979 Salt River collections. Protoptila maculata, a glossosomatid, was abundant in 1979 Brashears Creek collections, where it contributed almost 20% of the season’s total. In the Salt River, it was also common (9.2%) and its relative abundance changed very little from 1971 to 1979. DISCUSSION Within the Salt River drainage basin, paterns of land use and population distribution did not change appreciably from 1971 to 1979. The only significant activities to occur over the 8 year period were those associated with construction of the proposed dam _ outlet-works, visitors’ center with access roads, bridges, and the con- struction of Kentucky State Hwy. 55. Beginning in 1975, these activities generated chronic low levels of suspended solids which eventually entered the Salt River. In 1979, both Brashears Creek and the Salt River were characterized by moderate levels of suspended solids and turbidity, with levels in the Salt River usually higher than those in Brashears Creek. The caddisfly fauna was similar in these 2 streams, and species diversity values were comparable at the 2 sites with both communities demonstrating a mid-season low in species diversity. Four species, P. maculata, C. campyla, H. perdita, and C. cancellata, made up approximately 70% of the season’s total at both sites. Ratios among the various net spinners suggest that the fauna of Brashears Creek and the Salt River in 1979 is more similar than that of the Salt River in 1971 and 1979. An evaluation of the Trichoptera community in the Salt River based solely on collections in 1979 does not indicate a greatly stressed com- munity; however, a comparison of the caddisfly community in 1979 with that present in 1971 does suggest that changes have occurred. Ten species were collected in 1979 from the Salt River which were not found in collections in 1971 (Table 1). Included among these is N. vibrans, which was found in_ substantial numbers (1.5% season’s total in 1979), and is apparently a new state record for Kentucky (11, 12). The remaining 9 species collected from the Salt River in 1979 that were absent in 1971 col- lections, were present in very low numbers, often as single specimens. Variations in emergence synchrony may be responsible for failure to col- lect these species in 1971; alternatively, these rare species may be inhabiting a marginal habitat in the collecting area or may represent immigrants from other breeding habitats, e.g., Crichton (13). We found that species diversity did not change greatly from 1971 to 1979 (Fig. 2), although the season patterns of species diversity values is ap- preciably altered. For example, a midsummer low was present in 1979 Salt River collections, whereas in 1971 highest diversity values occur- red in midsummer. The very large numbers of C. campyla coliected in 1979 raised redundancy and consequently lowered diversity at this time, even though in both years the number of total species collected was highest in midsummer. Sorensen et al. (14) and others have noted that benthic communities are often maintained through succession of species; individual taxa may differ as sediment pollution persists, but estimates of diversity remain constant. We would expect this type of response in the benthos to be reflected in light-trap collections of adults (15). Although we did not see a decrease in species diversity values in the Salt River, and species Caddisflies in Kentucky — Haag et al. ‘richness in fact increased, major shifts in species composition and abundance were observed within several families from 1971 to 1979. For example, the underlying reason for the dramatic change in the ratio of hydropsychids to philopotamids (2:1 to 299:1) is the decline in abundance of Chimarra obscura, from 7.0% of the season’s total in 1971 to less than 0.3% in the Salt River in 1979. Turbidity and suspended solids levels in the Salt River frequently exceed the upper limits of tolerance observed for this species (2.5 to 51 NTU: 178—198 mg/1 total solids) that were reported by Harris and Lawrence (16). Chimarra obscura has a small net mesh size (Fig. 3). In addition, near the middle and posterior end of the net shelter, the mesh is covered with a sticky, gelatinous secretion that apparently aids in capturing small particles. The strands of the net, rather than forming a regularly arranged network, appears to serve as a support structure for the gelatinous material. This secretion is also susceptible to occlusion of fine, suspended sediments, which probably accounts for this species’ decline in the Salt River. Figure 3: Chimarra obscura collecting net, inner surface at posterior end. Roughness of some strands due to dried secretion. 2000X. Hydroptila perdita also showed a decline in relative abundance, from 15% in 1971 to 9% in 1979. Although little is known about the ecological requirements of species in the genus, it is generally thought that larvae feed on at- tached diatoms as well as on the contents of algal cells (17). Shading and abrasion of exposed surfaces by suspended solids may be particularly detrimental to larvae dependent on ‘periphyton food sources. Ceraclea cancellata appears to be propor- tionately less abundant in Salt River 1979 collec- tions (15% of total catch) than in 1971 (20%). 107 This species showed a 1979 emergence peak in June, similar to the peak seen in 1971, indicating that a difference in sampling schedules is not the source of the apparent change in abundance. Data on tolerance of this species to suspended solids are not available (16), but Resh and Unzicker (18), in their discussion of the genus Ceraclea (= Arthripsodes), suggested that some species in the genus may be more tolerant of pollution effects than others. Although the freshwater sponge Spongilla lacustris is fairly pollution tolerant, it is in- tolerant of sediment pollution (19). Thus, silta- tion changes are probably responsible for its decreased abundance. The similarity in relative abundance of C. transversa in 1971 (0.22%) and 1979 (0.19%) probably also reflects the ability of this species to function as a detritus feeder (20). Flynn and Mason (21) observed a decrease in the species number of hydropsychids in response to nonpoint sources of sediment pollu- tion. In contrast, the number of species in the Salt River did not decline from 1971 to 1979, although relative proportions of species of Cheumatopsyche varied. For example, C. cam- pyla was more abundant in 1979 than in 1971, whereas C. pettiti remained relatively constant. However, patterns of seasonal emergence for those 2 species remained similar in 1979 to those seen in 1971, with C. campyla more abundant earlier in the summer than C. pettiti. Cheumatopsyche spp. had been found in condi- tions of relatively high suspended solids (22). Thus, the population of C. campyla may be expanding in numbers to fill habitat vacated by other, less sediment-tolerant, net-spinning species. An examination of observed changes in the caddisfly community from 1971 to 1979 raises the question of what can be expected in terms of temporal variability in the absence of perturba- tions. Wolda (23), in research with tropical in- sects, used a parameter called Annual Variabili- ty (AV) to measure fluctuation in numbers of in- dividuals from one year to the next. McElravy et al. (24). applied this statistic to other data on temperate insect communities and found a range of values for AV from 0.080 to 0.325. Using AV to measure fluctuations seen in the Salt River from 1971 to 1979, we obtained a value of 0.925, which is several times greater than the maximum value reported above. The magnitude of this value suggests that, even though the data are not for successive years, the changes exceed those expected in the absence of increased siltation. Further changes are anticipated once the Taylorsville project is completed and flow augmentation for improving potable water quality if begun. Although construction-related 108 sediment generation will abate, suspended material will still enter the streams as runoff after precipitation. In the Salt River, as stream flow is regulated, the scouring effects of high flow conditions will no longer be available to help remove this accumulated material from the stream bed. Consequently, sediment may begin to fill in and cover over much of the benthic habitat. Continuing studies will examine further change in the Salt River caddisfly community.

RH - Mine-Roof Falls in West Virginia— Smith Geometry and Physical Characteristics of Mine-Koof Falls: A Case Study In The Upper Freeport Coal Seam Alan D. Smith Coal Mining Administration, College of Business Eastern Kentucky University, Richmond, KY 40475 ABSTRACT An initial data based in the Upper Freeport Coal Seam (Pennsylvanian age) was established, describing basic geometric and physical characteristics of coal-mine roof failure areas. Multiple linear regression analysis techniques were employed without correcting the decision criteria for multi- ple comparison, in order to maximize the possibility of detecting significant relationships. A total of 21 mine-roof falls were measured for 15 geologic or engineering parameters associated with roof failure. The averages for the parameters studied were: thinnest immediate roof layer is (0.427 cm) maximum roof height about roof edge or top of surface originally cut (2.86 m), height to second horizon or break-plane above roof lie (1.83 m), third horizon (p. 65 m), fourth horizon (0.41 m), length | of roof bolts used during resupport (1.75 m), span of mine entry (5.59 m), and vertical opening of entry (2.71 m). The majority of falls showed no presence of water, occurred mainly in intersections or en- tries, used resin bolts during resupport, dome-shaped roof falls, no presence of cracks in roof top after fall occurrence, and showed presence of rib sloughing. In terms of the hypothesis testing and model building, only 6 out of a total of 45 hypotheses were found to be statistically significant. Both parameters, presence of water and height to second break-horizon of roof strata were found to be significant in predicting maximum roof height. Location of falls in intersections and length of roof bolts accounted for a significant amount of explained variance in discriminating dome-shaped roof falls. INTRODUCTION Roof control is one of the most important | phases of underground mining and, coupled | with mine ventilation requirements, is a major | determinant of width of working spaces, opera- j tions at the mining face, and eventual sub- : sidence. Mine roof control is a nonending task | that must be continued for the life of the mine. | Hence, ground control measures may frequently | be the largest single cost item in the develop- ) ment and actual production of underground coal |mines (1). In order for mine roof predictive | models to be effective, in-situ studies associated ‘with the geology of the immediate roof and ‘floor, strength properties, and stress states are needed as basic inputs. The basic thrust of this | study is to examine the geometry and associated ‘failure parameters of roof falls in a West Virginia coal mine, mining in the Upper-Freeport Coal ‘Seam (Pennsylvanian age), to establish such a ‘basic data bank and to determine if predictive relationships exist between roof fall geometry ‘and associated mine roof failure parameters. 109 GEOMETRY OF ROOF FALLS The basic geometry or shape of a roof fall depends greatly upon the stresses placed on the roof and floor (2,3,4). Laminar and dome- shaped falls are basically the result of tensile stresses and associated geological features or deficits in the roof strata (Fig. 1). These geometries are characterized by low horizontal stresses, incompetent floor and ribs as com- pared to the mine roof, jointed roof and ribs, and beds in the roof sagging independently of one another. A major difference between laminar and dome-roof falls is the location of the in- tersection of the separation planes. If the separation planes intersect on a bedding plane, laminar roof falls may develop; if separation planes intersect inside a bed, a dome-shaped roof fall geometry may develop as a result of high compressional stresses (Fig. 1). They are usually characterized by high horizontal stresses, which are common in the Eastern Ken- tucky Coal Field, large amounts of overburden, thin immediate roof beds, and very competent floor and ribs as compared to the immediate roof. Under these conditions the separation 110 planes usually will intersect at some point in the immediate roof and form arched-shaped roof falls. 1.

As evident in the tables, only 6 hypotheses out of a total of 45 were found to be Statistically significant for a two-tailed, non- directional test at 0.05 or 0.01. Both parameters, presence of water and height to second break horizon of roof strata above the roof edge were found to be statistically significant in predicting maximum roof height. However, no corrections were made to correct he decision criteria for multiple comparisons, since it was decided to maximize the possibility of detecting difference if they occurred. The parameter, presence of water, accounted for 20 per cent of the explained variance (p = 0.0421) in discriminating max- imum roof height above the roof line. In general, a greater presence of water was associated with higher roof falls, as is to be expected, due to the greater hydrostatic pressure causing roof layers to separate and eventually fail. In addition, height above the roof line to the second horizon- tal strata of the roof fall accounted for over 95 per cent of the explained variance in predicting maximum roof fall height (p = 0.0000). Thus, higher vertical heights to the second roof strata were associated with greater overall roof heights. However, there appeared to exist no statistically significant relationships in discriminating or predicting maximum _ roof height and the following variables: location of the roof fall, vertical height to third roof strata in mine roof, spacing of the bolts before the fall, type of support before fall, spacing of the bolts after the fall, type of support after fall, length of bolts before the fall, length of bolts after the fall, span of mine entry, cracks, sloughing of coal ribs, vertical opening of the entry, and thickness of thinnest, immediate, mine roof-rock layer. 6.

However, the height to the third break-plane or roof rock strata was found to account for a statistically significant amount of explained variance (39.43 per cent), in predict- ing height to second strata of mine roof fall (p = 0.0519). Both variables were found to be positively correlated. The other parameters, similar to those tested with the other dependent variables, were also not found to be statistically significant. TABLE 4.

Also found in Table 4 is a summary of the hypothesis testing and model comparisons in discriminating the shape of mine roof falls (dome-shaped) and selected parameters. Only 2 of the 15 hypotheses were found to be statistical- ly significant at the 0.05 level. The parameters location of the roof fall (intersections) and length of bolts used after the fall were found to be significantly correlated to the geometry of the falls. As illustrated in Table 3, location of the Mine Roofs in West Virginia — Smith 115 falls in intersections accounted for a significant amount of explained variance (27.80 per cent) in discriminating dome-shaped roof falls. Hence, a greater occurrence of dome-shaped falls are associated with intersections. When considering the nature of intersections and the stress con- centrations equally spaced on the abutments, this conclusion is supported by previous findings (3,5). In addition, the length of bolts used after the fall were significantly related (p = 0.0482) in discriminating dome-shaped falls (Table 3). The relationship is negatively correlated, thus shorter length of roof bolts used to resupport the fall were associated with a greater occurrence of dome-shaped roof falls. Since many of the falls are several generations in reoccurrence, shorter bolts used to resupport the fall may cause a more uniform and relatively shallow roof horizon to fall, forming an equidimensional, dome-shaped geometry. The other 13 parameters previously tested in Table 4 were not found to be statistically significant in discriminating roof fall geometry. 8.

CONCLUSION Hence, as evident in an inspection of the overall findings, a basis for a profile of mine-roof falls associated with the Upper Freeport Coal Seam, located in West Virginia, can be established. With this data base established, coupled with future studies of mine roof falls describing similar characteristics, predictive models for use in forecasting and eventual prevention of major ground control problem areas may be attempted in Appalachian coal mines.

RH - Mine Planning in Kentucky— Smith Dimensional Analysis of Coal Pillars: An Application of Cost-Sensitive Mine Planning Principles to a Southeastern Kentucky Mine Alan D. Smith Coal Mining Administration, College of Business Eastern Kentucky University, Richmond, KY 40475 ABSTRACT The cost-sensitive mine planning process involves spatial projection of the geological and economical conditions that will have the greatest impact on cost and coal quality for a particular mine site. A comparison of actual, maximum safety, and recommended pillar dimensions and their associated factors of safety, based on the theories of Salamon, Salamon and Munro, Bieniawski, Bieniawski, Rafia, and Newman, and Skelly, Wolgamott, and Wang, which cover a broad spectrum of mining conditions, were made for a small coal mine near Leatherwood, Kentucky in southeastern Kentucky. From a preliminary and economic forecasting viewpoint, the traditional 40-foot square pillar appears to be too large, at least from the standpoint of overburden thickness and common lithologic characteristics found in the eastern Kentucky coal fields. The alternative system of room- and-pillar mining with 34-foot pillars and conservative 20-foot entries would allow for 5 entries to be developed in the same area of coal, which would result in an increase of 320 tons of raw coal per move up. Assuming the price of coal is $32 per ton and standard coal preparation losses at 20 per cent, additional revenue of about $8,200 per move up would be realized. This increase in cash flow is especially important in developmental stages of underground mining, due to the shortage of cash flows. INTRODUCTION layout.

In depth of overburden over the proposed mine fact, these development entries, being service 116 Mine planning in Kentucky — Smith entries for such vital services as ventilation, power distribution, escapeways, haulage avenues, are the main pulse of the daily routine in underground mining and, hence, must be maintained in a safe and adequate manner (3). The design of pillars involves the deter- mination of proper size pillars for certain loca- tions in line with the expected load history. The data generally required in the design of pillars are: (1) the expected load history, including premining pillar loading and mining-induced abutment pressure; (2) stress distribution within the pillar; (3) pillar strength; (4) interaction be- tween roof, pillar, and floor. Some types of mining, compared to mining bedded-deposits, require different shapes of pillars and some differences in the _ pillar geometry. Bedded deposits, such as coal and limestone, may require the height of pillars to vary over a considerable range, from as low as 2 to a high of 80 feet. However, in ore bodies, the height variation may even be greater. In addi- tion, nearly all materials show a creep effect with time when placed under varying magnitudes of stress. In many cases, the ultimate effect of creep in coal is difficult, if not impossible, to forecast. However, the technology of designing coal pillars is presently further advanced than similar technology in designing pillars for other minerals. For these and other reasons, 3 pillar formulas have been selected for use in this study in relating pillar strength to its geometry and structural material in the mine site. The 3 pillar formulas cover a broad enough spectrum of conditions to be of general applicable value. The formulas to be us- ed in the present study were derived by Salamon (4), Salamon and Munro (5), Bieniawski (6), Bieniawski, Rafia, and Newman (7), and Skelly, Wolgamott and Wang (8). The design of a room and pillar layout necessitates the knowledge of the size of coal pillars that will act as a permanent support to the immediate roof strata until the depillaring operation stage, if any. Many investigations have been carried out in studying the most stable dimensions of a pillar. Salamon (4), Salamon and Munro (5) developed an empirical formula by which the approximate strength of a pillar may be determined. Salamon et al. (loc. cit.) based this formula upon back-analysis derived from underground information and per- formance of stable and collapsed, or failed, | pillars: Sp = 1320 w-46 140.66 | Where Sp is the pillar strength, W is the width of 117 the pillar, and H is the height of the coal seam in inches. Of course, stable coal pillars are likely to deteriorate due to weathering or creep; therefore, it is necessary to take into account the strength and time dependent properties of the coal seam and surrounding strata. This process of coal pillar deterioration may be accelerated if undermined by previous room and pillar work- ings. In addition, the stability of the immediate roof strata may be lessened by deterioration. Room and pillar designs are particularly sen- sitive to the ability of the roof of the entries to be self-supporting (9). According to Bieniawski (6) and Bieniawski, Rafia, and Newman (7), the strength of a coal pillar may be approximated by: Sp = 650 (0.64 + 0.36 W/H) Again, the symbols are the same as previously defined for Salamon’s equation. Skelly et al (8) developed the following equation for predicting the strength of the pillar: Sp = 650 (0.78 + 0.222 W/H) This formula is fairly similar to Bieniawski’s, but reflects more of an attempt to modify Bieniawski and Salamon’s work to suit the conditions found in the Appalachian coal fields. Upon computing a pillar strength by the above formulas, they can be compared to the actual calculated stress applied to a particular pillar, and a factor of safety can be determined. A factor of safety is simply the stress on the pillar divided into the strength of the pillar. Salamon recommended a factor of safety ran- ging from 1.3 to 1.9, with 1.6 being associated with a stable pillar; Bieniawski et al. and Skelly et al. collectively recommended 1.0 to 3.0, with 2.0 being the factor of safety associated with a stable pillar. Of course, there are ranges in the factors of safety, since different mining condi- tions may warrant more conservative or more liberal pillar dimensions. However, the smaller the factor of safety, the smaller the coal dimen- sion, and the greater overall coal recovery. The determination of the actual stress on the pillar can easily be determined, assuming tributary loading and not pressure arch theory, by the following formula: op = yd (We + Wp)? Wp? Where 5p is the actual stress on the pillar, y is the weighted density of overburden over the coal pillar, d is the depth to the top of the coal seam, We is the width of the entries or roof between pillars, and Wp is the width of a square pillar. 118 Trans. Kentucky Academy of Science — 45(3-4) The above formula can be modified for a rec- tangular pillar by using the length of the pillar as well: 55 = yd (We + Wp) (We + Lp) (Wp) (Lp) Where the only new term, Lp, is simply the length or longest dimension of the rectangular pillar. METHOD Study Area A small southeastern Kentucky coal mine near Leatherwood, Kentucky is owned and operated by a large mining company that will re- main unidentified for proprietary purposes, was studied to apply the cost-sensitive mapping pro- cedures suggested by Ellison and Scovazzo (1). A typical small Kentucky coal mine is usually shallow (between 200 to 500 feet (60 to 150 m) of vertical overburden) and of relatively short dura- tion. Therefore, the motive is to derive as much minable coal in as short a time as possible. This small mine is operated in a thin coal seam, ranging between 40 and 72 inches, with a sand- stone/siltstone partition of approximately 12 in- ches in parts of the mine. The coal seam is essentially flat-lying, with some gentle folds causing a maximum in the seam’s elevation of 25 feet above and 20 feet below the seam’s eleva- tion at the driftmouth or mine entrance. In addi- tion, the seam dips slightly to the west. The overburden is very shallow in that the deepest cover is 350.2 ft. (106.74 m) in thickness and the average depth is 265.6 ft. (80.95 m). The im- mediate roof is sandstone, which is considered a hard and competent strata; unfortunately, in this mine it is highly fractured and weakened. The mine has a predicted life expectancy of 3 to 5 years for development mining and 3 to 5 years of retreat mining. Mining Methods to Produce Coal A large mining company that owns and operates the small mine uses the continuous mining method in the room-and-pillar system. Continuous mining reduces the mining cycle compared to that of the conventional method by removing some pieces of the equipment and associated miners to operate it, thus increasing productivity. The continuous mining method uses one machine to break the coal loose where the conventional method uses _ several machines, such as the horizontal drill and front- end loader or load-haul-dumpers (LHD). The continuous miner has teethed drums that rotate against the coal and breaks it up. The broken coal then travels to the tail of the miner via a chain conveyor and is loaded onto a shuttle car. The shuttle car then travels to a belt conveyor and unloads the coal. The beltline then take the coal to the driftmouth. However, the shuttle car must travel a route which is designed to minimize the number of corners turned and, hence, the total distance traveled. Since the continuous miner can cut coal fast enough to keep 2 cars busy, these cars must be scheduled to cut down on idle time and avoid potential ac- cidents. Once the miner moves on to its next cut, a roof bolter is moved in to install im- mediate roof supports. Usually, 2 roof bolters are required to keep up with the continuous miner in this mine. The bolting machine drills holes into the immediate roof to a depth which reaches a stronger layer of rock or anchor horizon. Roof bolts vary in lengths from 28 in- ches (0.71) to 8 feet (2.44 m) and come in 2 general types. The first type uses an expanding shell that flares out as the bolt is torqued against the roof. This flaring creates the pressure that causes the bolt to hold up the im- mediate roof through tension. The second type of bolt uses resin to create the hold between it and the rock strata. As the resin flows into the cracks in the rock it solidifies and this contact creates the tension needed. Of course, the resin bolt is more expensive, and is employed in very bad roof top areas for better ground control. The mining system used is that of room- and-pillar. The room-and-pillar mining method is traditionally used in the many small coal mines of southeastern Kentucky. In room-and- pillar mining, entries are driven into the coal seam at its outcrop. As the entries develop, crosscuts are made to join the entries for ventila- tion and coal haulage purposes. The number of entries varies in typical room-and-pillar mines from 2 to 8 or more. Two entries are minimally required to get proper ventilation flow with one entry being used for intake air and the other for exhaust air. However, most mines in the area, and including the one under study, use one entry for a track to take in men and supplies and another for the beltline to come out. These en- tries require the presence of workers and, hence, cannot be exposed to exhaust from the coal face, 3 intake entries are usually used. The number of entries increases once the mine develops further to increase productivity through the prevention of delays in the mining cycle. The action of driving entries and crosscuts leaves pillars or columns of coal to support the roof. Room-and-pillar mining assumes the tributary load concept, although the pressure arch theory can be applied in selected areas to Mine planning in Kentucky — Smith relieve part of the load on main and submain pillars. Under the tributary load concept, each pillar is assumed to uniformly support the weight of the rock overlying the pillar and mid- way the span of the entry or room on each side of the pillar. Pillar Dimensional Design An average depth of overburden was assumed to be 265.6 feet (80.95 m), average density of over- burden of 160 Ibs/ft* (2.86 g/cm’, the standard often used in association with sedimentary lithologies found in Kentucky), coal seam height of 5 feet (1.52 m), width of entries to be 20 feet (6.10 m), a calculated overburden or geostatic pressure of 657.36 Ibs/in? on a 40 ft. (12.19 m) pillar in performing a_ pillar dimensional analysis. Factors of safety and recommended pillar sizes were also calculated, using the theories of Salamon et al. (5), Bieniawski (6), Bieniawski et al. (7), and Skelly et al. (8). RESULTS AND DISCUSSION Pillar Dimensional Analysis and Associated Factors of Safety Once having the mean, actual stress on the pillars presently used in the mine near Leather- wood, Kentucky calculated, the pillar strength can then be calculated, according to the previously discussed design equations. The cor- responding factors of safety can be calculated, since, as stated earlier, the factor of safety is simply the relationship of pillar strength, whether based on ultimate strength or pro- gressive failure criteria, to the mean, actual ver- tical stress acting on the pillar. Table 1 sum- marizes the various factors of safety associated with a 40-foot square pillar, maximum safety, and recommended for safe-rigid pillar according to the theories of Salamon (4), Salamon and Munro (5), Bieniawski (6), Bieniawski, Rafia, Newman (7), and Skelley, Wolgamott, and Wang (8). The figures in the table were based on the qualifying assumptions previously stated in the methods section. As evident from a quick in- spection of the table, the 40-foot pillar is over- designed, since the associated factors of safety are noticeably larger than the factors of safety for a pillar of maximum safety for all but one theory (8). The factors of safety for a recom- mended safe-rigid pillar, based on the tributary load concept is lower than the actual pillars’ fac- tors of safety for all 3 theories. Since there is a direct relationship between pillar width and fac- tors of safety, the larger factors of safety repre- sent unnecessary waste of coal that could have been mined, instead of left for support and ground control. Of course, this means that by 119 using a standard and oversized pillar, based on precedent or practical experience, a much reduced coal recovery results and, hence, diminished profits. To find the proper size pillars under these conditions, the pillar dimensions should be recalculated at the recommended fac- tors of safety for each theory explored and back- calculated the optimum pillar dimensions to maximize coal recovery.

The trial and error solutions for pillar dimensions, using the factors of safety for max- imum safety and recommended dimensions can be found in Table 2. The recommended pillar dimensions range from a high of 34 feet (10.36 m) for Skelly et al. (8) and a low of 21 feet (6.40 m) Salamon (4) and Salamon and Munro (5). Of course, these pillar dimensions may be enlarged to counter the effects of deterioration resulting from exposure to moisture in the ventilated air as well as other factors. However, this mine, as well as similar mines in southeastern Kentucky are of limited duration, therefore the deteriorating effects of moisture in the at- mosphere will have minimal effect. However, from a preliminary and economic fore- casting viewpoint, the traditional 40-foot square pillars that this mining company is using in this particular mine appears to be too large, at least from the standpoint of overburden thickness. This statement is further evidenced by the absence of noticeable numbers of mine roof falls; thus, this is another indication that the pillar dimensions are too conservative in the overall mine layout. 120 Trans.

Presently, based on 40-foot pillars, the coal extraction ratio is approximate- ly 56 percent. The extraction ratio for a 34-foot pillar, based on the largest recommended pillar dimension from the calculations utilizing Skelley et al. (8), is 60 percent. Of course, if the width of span of the entries between pillars were allowed to increase, then the corresponding ex- traction ratio would increase drastically. Although the percentage increase appears to be small, the tonnage of coal recovered will have a significant impact on tonnage produced. The 40-foot pillar has a volume of coal of 8,000 ft.2 (226.53 m’) while the 34-foot pillar has a volume of 5,780 ft.’ (163.67 m‘*). Thus, a difference of 2,220 ft.? (62.86 m‘) in the 40-foot pillar that could be mined by utilizing a system of 34foot pillars. Assuming coal has a unit weight or density of 80 Ibs/ft* (1.43 g/cm*) and multiplying this by the difference of 2,220 ft.°, a total weight of raw coal of 177,600 Ibs. or 88.8 tons per pillar is available, if the entries are allowed to expand. However, if using the original entry system of 40-foot pillars and main- taining the same 20-foot entries with a four-entry system means 200 linear feet (61 m) of coal from rib to rib is being mined. The alternative system of 34-foot pillars would allow for 5 entries of 20 feet each in the same area of coal. The 4entry system will provide 1,120 tons per move up and five-entry system will provide 1,440 tons per move up which results in a difference of 320 tons per move up. Assuming the price of coal is ap- proximately $32 per clean ton and a standard coal preparation recovery of 80 percent, this would bring in $8,192 per move up during development mining. Once the development mining is finished the remaining coal is partially removed where possible by a process known as robbing or retreat mining. However, it is during development stage of mining that cash flows are a major problem, especially in the fluctuating coal markets of today. Hence, the additional revenue during this stage is of extreme impor- tance, especially to the owners and operators of small coal mines, such as this one _ in Leatherwood, Kentucky. CONCLUSIONS As demonstrated in the _ preliminary analysis and discussion of recommended pillar dimensions, based on overburden thickness and common properties of rocks contributed to the eastern Kentucky coal fields, the mining com- pany may be too conservative in its approach to its Leatherwood Mine. This point is well taken, since results obtained from all 3 diversed pillar- dimensional theories point to the same conclu- sion of oversized pillars. The overdesigning of pillars may be costly, as evident by the simple cost/benefit analysis previously illustrated, utilizing the principle of cost-sensitive planning. Hence, the current design of coal mine pillar pillars in southeastern Kentucky can be significantly improved by selecting a more ap- propriate pillar strength formula and more realistic safety factors. The state of rock mechanics and mining engineering is such that mine planners can be more effective in the overall desing of the pillar dimensions in ad- vance of mining operations, development, and eventual production.

RH - Orientation in White-Throated Sparrow - Pauly and Ferrell Sunset as an Orientational Cue for a Nocturnal Migrant, the White-throated Sparrow (Zonotrichia albicollis). James R. Pauly’ and Blaine R. Ferrell Western Kentucky University, Bowling Green, Kentucky 42101 ABSTRACT The possibility that nocturnal migrants use sunset as an orientational cue was explored using the white-throated sparrow (Zonotrichia albicollis) in a series of experiments conducted between 1 April and 24 April, 1981. Orientation tests were performed on the roof of the biology building at Western Kentucky University with birds assumed to be in proper physiological condition for migra- tion. Birds exposed only to the night skies, birds isolated from all visual cues, and birds exposed to both day and night skies did not exhibit the northward directional preference appropriate for the spring season. However, white-throated sparrows exposed only to the sunset and tested in the absence of visual nighttime cues exhibited significant orientation northward. These data support the hypothesis that white-throated sparrows can use the sunset as an orientational cue. INTRODUCTION Various environmental cues are available for the orientation of migrating birds (1,2,3). The use of several orientational cues may increase the accuracy of a migrant’s heading but con- founds efforts to establish which cues are actual- ly utilized. The possibility that nocturnal migrants use the position of the setting sun as an orientational cue was first suggested by Kramer (4). The casual observations of Kramer were followed by several field experiments that more strongly implicated the sunset as an im- portant orientational cue to nocturnal migrants (5,6,7). In 1978, Frank Moore (8) provided more direct evidence that directional information derived from the sunset was used by a nocturnal migrant, the savannah sparrow (Passerrulus sanduichensis). Bingman and Able (9) per- formed similar experiments using white- throated sparrows (Zonotrichia albicollis) tested in an autumnal migratory condition. Although the data presented by these authors are suppor- tive of the hypothesis of sunset as an orienta- tional cue, their experimental protocol did not measure the orientational response of birds ex- posed only to the sunset and tested in the absence of night sky orientational cues. Therefore, the present study was carried out in order to investigate more rigorously the possibility that sunset is an important direc- tional cue used by white-throated sparrows during spring migration. ?Present Address: Department of Biology, MATERIALS AND METHODS During January and February, 1981, 38 winter-resident white-throated sparrows were captured by mist net or live traps in the vicinity of Bowling Green, Kentucky. Orientation tests were conducted on the roof of the biology building on the campus of Western Kentucky University from 1 April to 22 April, 1981. All birds were maintained indoors under 14L:10D before the test periods and were judged to be ina migratory seasonal condition based upon easily observed criteria, such as enlarged gonads, in- . creased fat stores, and nocturnal unrest (Zugunruhe) (10). Locomotor activity was monitored using perches that rested on microswitches interfaced with an _ Esterline- Angus event recorder. Subcutaneous fat stores were examined visually weekly and gonad size was determined monthly by unilateral laparotomy. Four treatment groups were established. Birds in one experimental group were exposed to the open night sky during the test period but were maintained in photoperiod chambers on the roof at all other times. In another ex- perimental group, birds were placed in holding cages where they were exposed to the sun begin- ning one hour before sunset. Birds in this same group were denied exposure to the nighttime sky during the test period and maintained in photoperiod chambers at all other times. A third group of birds (Control Group 1) was ex- Marquette University, Milwaukee, Wisconsin 53233 122 Orientation in White-throated sparrow - Pauly 123 posed to both sunset and the nighttime sky. Birds in the fourth group (Control Group II) were maintained in photoperiod chambers during the day and were denied exposure to the nighttime sky by a black plastic cover during the test period. In order to provide a stimulatory photo- periodic schedule, 15-watt fluorescent bulbs were attached to the holding cages located on the roof. Twelve Emlen funnels (i.e., 3 from each test group) were placed in an orientation chamber on each test night. The walls of the test chamber were lined with black plastic and ex- tended 12 inches above the Emlen funnels, thus denying the test birds a view of landmarks on the horizon. Birds housed in one-half of this chamber were denied exposure to the night sky by an opaque black plastic cover. The half of the chamber that housed birds allowed exposure to the night sky was covered with a clear plastic in order to keep the treatments as consistent as possible. Birds were tested for two hours begin- ning at 1930 hours (i.e., approximately one hour after sunset), a time of night appropriate for the initiation of spring migratory flights. The footprint method described by Emlen and Emlen (11) was used in tests for orientation. The test unit consisted of a blotter paper funnel which was supported by a cardboard funnel. The small ends of these funnels were placed in two- quart aluminum pans and the entire apparatus was covered by quarter-inch hardware cloth fastened to the aluminum pan. A slit cut in the lower side of each aluminum pan facilitated the insertion of foam ink pads into the test funnels. The pads were saturated with india ink on each night of use. A bird placed in the funnel thus was standing on an ink pad surrounded by outwardly sloping walls of blotter paper. The forward movement of a bird resulted in black footprints on the paper. It was the accumulation of these footprints that created the orientation record of a bird. A total of 144 bird-nights (i.e., 36 replica- tions from each test group) of orientational data was generated. For statistical purposes, foot- print records were quantified according to a method reported previously (11). Mean angular directions of activity were calculated and tested for significance according to the method described by Zar (12). Since white-throated sparrows breed throughout the northern United States and southern Canada, mean angular directions between 270 and 90 degrees were con- sidered appropriate orientational choices for the spring season. Zero degrees represented due north. RESULTS AND DISCUSSION Birds exposed to sunset only were the only ones that exhibited an appropriate directional choice that was statistically significant (Table 1 and Figure 1). The activity of this group was the lowest among all groups tested but this activity was precisely oriented. Table 1.

The fact that birds exposed to daytime and nighttime skies did not orient consistently in the appropriate direction is not in accordance with reports of previous studies (9). Although we at- tempted to exclude extraneous light sources, such as horizon glow, through the orientation test chamber architecture, it is possible that these birds were directing their activity toward the glow created by the city lights of Bowling Green located southwest of the orientation test site. This supposition is supported by the fact that many birds exposed only to the night sky also chose this direction. Birds denied exposure to the night sky by a black plastic cover showed little tendency to orient in this direction. 124 nighttime sky only neither sunset nor E nighttime sky sunset only E both sunset and nighttime sky Figure 1.

Triangles represent group mean angular directions. Open triangles represent a non-significant directional choice and the shaded triangle (sunset-only group) represents a significant directional choice. Results of this study do not indicate the use of magnetic cues in orientation by white- throated sparrows. If the earth’s magnetic field was a source of orientational information, then correct orientational responses should have oc- curred consistently in all treatment groups. The fact that Emlen funnels are too small for a response due to geomagnetic fields might ac- count for the observed lack of response. It has been reported that birds exhibit a weak response to geomagnetic cues when placed in Emlen fun- nels (13). Although results of this study do not support the concept that nocturnal migrants can use magnetic fields as orientational cues, our results do indicate that the position of the sun at sunset is in fact an important orientational cue used by a nocturnal migrant, the white-throated sparrow.

RH - Microbiological Sampling Device - Lisle and Mardon A Convenient Apparatus for Microbiological Sampling of River Waters John T. Lisle’ and David N. Mardon? Eastern Kentucky University, Richmond, Kentucky 40475 ABSTRACT A compact water sampler for the collection of microorganisms from selected depths in both lentic and lotic waters is described. INTRODUCTION A prerequisite to quantitative studies of aquatic microbial populations is a specimen- sampling apparatus suitable for collecting from desired depths (2, 7). Various investigators and organizations have developed samplers accord- ing to their specific needs (1, 4, 5, 6, 7). However, each of these samplers has features which can restrict its application. Some pro- blems within the above group of samplers are; capacity limitations, sterility of the sample con- tainer, lateral stability in lotic waters, unreliable collection of samples from specific depths, dif- ficulty in the rapid replacement of broken parts, compact storage, and inconvenience or inability for varying the length of the sampler to allow collection at selected depths. The Eastern Ken- tucky University (E.K.U.) water sampler described below was designed to minimize these difficulties during the collection of microbial samples from the Kentucky River. CONSTRUCTION OF THE E.K.U. MICROBIAL WATER SAMPLER The collecting section of the sampler con- sists of a 0.6 m piece of 31.89 mm by 1.6 mm aluminum frame, bent to accommodate biochemical oxygen demand (B.O.D.) bottles or similar vessels up to 500 ml in capacity (Fig. la). This aluminum frame is fastened to one end of a 0.9 m section of polyvinylchloride (PVC) tubing via two 63.1 mm by 4.8 mm round head bolts, lock washers and nuts (Fig. 1c). The bottle is held onto the frame by a stainless steel flask holder and an adjustable stainless steel hose clamp (Fig. 3c and 4c). The removable flask holder, which may be selected for any size flask from 25 ml to 500 ml capacity, is connected to the aluminum frame via a 4.8 mm flat-head bolt (Fig. 3d and 4d). ' Present Address: City of Tampa Water Department, Production Division, 7125 North 30th Street, Tampa, Florida 33610. The shaft of the sampler is made of 0.9 long sections of 25.4 mm diameter PVC tubing witha sleeve glued in place at one end of each 0.9 sec- tion (Fig. 1b). This modification of the PVC tubes allows convenient fitting of sections when expansion of the sampler shaft is desired (Fig.2). Near each end of the 0.9 m PVC sections are two holes to accommodate a 63.1 mm by 4.8 mm round head bolt which can be passed through the aligned holes of the joined PVC sections, then secured with a 4.8 mm wing nut and washer (Fig. 2a). Inside each PVC section is a 1.1 m by 4.8 mm threaded rod with a threaded sleeve at one end (Fig. 1d). At the collecting end of the sampler is another 4.8 mm threaded sleeve attached to the initial threaded rod (Fig. 3e and 4e). A 63.1 mm diameter by 4.8 mm ad- justable spacer secured by 4.8 mm nuts on each side is located at the desired position on the in- itial threaded rod above this sleeve (Fig. 3a and 4a). The location of the spacer disk can be ad- justed to accommodate the height of the bottle fastened to the collection section of the sampler. Normally, this spacer is adjusted so that when the immersed bottle is opened, the stopper will not be pulled out of the lip of the bottle farther than 1.5 cm thus, allowing the stopper to re- main aligned with the bottle opening (Fig. 4). Each bottle is sealed with a separate rubber stopper of appropriate size which has a flat head bolt 50.89 mm long by 4.8 mm inserted through its center (Fig. 3b and 4b). The head of this bolt is at the bottom of the stopper and is covered with a thin layer of silicone to prevent metallic leaching. The threaded bolt protrudes through the top of the stopper and therefore can readily be attached to the sleeve on the end of the initial threaded rod. Each bottle and stopper can be sterilized (autoclaved) as a unit and stored prior to use.

COLLECTION OF MICROBIAL SAMPLES A sterile stoppered vessel (B.O.D. bottle) is clamped onto the flask holder. The threaded rod at the collecting end of the sampler is fastened to the extended threads of the stopper bolt via a threaded sleeve (Fig. 3b and 4b). The sampler is the lowered to the desired depth and the central threaded rod pulled up until its movement is stopped by the spacer disk. This procedure removes the stopper from the bottle allowing it to fill with water. When the bottle is full the cen- tral rod is pushed back down forcing the stopper back into the bottle. The apparatus is then retrieved, the sample bottle removed and either stored temporarily or prepared immediately for microbial counts. DISCUSSION The prerequisites for a versatile microbial water sampler are satisfied by the E.K.U. pro- totype. Its performance was excellent during a six month study on a section of the Kentucky River at sampling depths between 1.0 m and 9.0 m (3). The E.K.U. sampler’s simple construc- tion, rugged design and versatility should enhance its usefulness for research, industrial and educational purposes. The ability to use sampling bottles with volumes between 25 ml and 500 ml is an advantage as is maintenance of the integrity of a sample from a particular depth during retrieval. Once at a desired depth the bottle can be readily opened, filled, then closed by an operator on the surface. Furthermore, since the stopper is opened and closed manually and there are no messengers, incomplete samples and broken parts are rare. The rigid shaft construction with its permanent sounding marks allows the sampler to be lowered to a specified depth with minimal lateral drifting in lotic waters. The use of shaft sections 1.1 m in length facilitiates assembly and dismantling of the E.K.U. sampler as well as its storage in a limited space, such as a small vehicle or boat. ACKNOWLEDGEMENT We wish to thank Mr. William Henderson for his technical assistance in the construction of the E.K.U. water sampler. LITERATURE CITED 1. Geldreich, Edwin E., Harry D. Nash, Donald F.

RH - Wintering Raptors in Kentucky - Sferra Population Densities of Diurnal Raptors Wintering in Madison County, Kentucky Nancy J. Sferra Department of Biological Sciences, Eastern Kentucky University Richmond, Kentucky 40475° ABSTRACT Between December 1980 and March 1981 population densities of wintering diurnal raptors were determined using an automobile strip census. Winter population density estimates/km? were 0.19 Kestrels (Falco sparverius), 0.09 Red-tailed Hawks(Buteo jamaicensis), 0.05 Rough-legged Hawks (B. lagopus), 0.05 Northern Harriers (Circus cyaneus), 0.004 Red-shouldered Hawks (B. lineatus). 0.003 Sharp-shinned Hawks (Accipiter striatus), and 0.001 Cooper’s Hawks (A. cooperii). INTRODUCTION Winter raptor population studies have been performed in many areas (1,2,3,4,5), but no such research has been conducted in central Kentucky. In Madison County, raptors may be an important part of the winter bird community because extensive areas of pastureland and other open habitats potentially support high prey populations. The purpose of the present study was to determine population densities of diurnal raptors wintering in Madison County, and to record temporal fluctuations in those densities. MATERIALS AND METHODS Diurnal raptor populations were sampled by means of an automobile strip census (6) of the secondary roads in Madison County, Ken- tucky. The census route was chosen so that it covered each of the 4 physiographic regions of the county: the Hills of the Bluegrass, the Outer Bluegrass, the Knobs Section of the Cumberland Plateau, and the Mountains (7). One census was run per week beginning in late December 1980 and ending in March 1981, for a total of 10 censuses (Table 1). Each census covered 235 km; none was taken whenever visibility was hampered due to fog, snow, or rain. * Present Address: Department of Zoology, Michigan State University East Lansing, Michigan 48824. 128 Table 1.

The routes were driven at speeds between 32 and 48 kph, and all raptors seen on each side of the road were recorded. Craighead and Craighead (6) assumed that all raptors present within 0.40 km of the road could be sighted, and this assumption was used in the present study. Each raptor sighting was plotted on a map of the study area after estimating the distance of the bird from the road. All distance estimates were made by the same person to ensure consistency. Only raptors identified to species were included in density estimates. Although Turkey Vultures (Cathartes aura) and Black vultures (Coragyps atratus) were present in the area, they were not included in this study. Both species are most common in highly dissected terrain with vertical rock walls (8); they could, therefore, not be ac- curately counted using an automobile census.

The there was a dramatic increase in Kestrel lowest tally occurred during census 9 when only —_ numbers during census 10 (38 sightings), prob- 21 Kestrels were seen. This decline may have ably due to a wave of migrants moving through been due to winter mortality and behavior the area. Behavior associated with the breeding changes brought about by unusually cold season could also have contributed to the high weather conditions. Mills (5) found a sharp count due to the conspicuousness of courtship decline in Kestrel populations in central Ohio flights and increased numbers of paired birds. following the first cold spell of the winter, and Mean Kestrel density for the winter was Enderson (9) was able to correlate low 0.19/km* (Table 2). In Colorado, lower temperatures and low Kestrel numbers in east- _—_ estimates were obtained on grazing and wheat central Illinois. In Madison County, the first cold lands of the plains immediately east of the spell occurred during a 9-day period beginning Rocky Mountains, where habitats were probably on 5 January. During that time, the minimum less diverse than in Madison County (10). Far daily temperature was below - 12°C for 8 out of higher estimates were obtained in Florida (11), the 9 days. Decreasing Kestrel numbers, begin- _ where Kestrel densities included two subspecies, ning during census 2, coincided with the period F.s. paulus, a resident race, and F.s. sparverius, of cold weather. a winter migrant. Only one subspecies, F.s. 130 sparverius, is present in Madison County (8). In addition, milder weather conditions in Florida could have contributed to higher densities. The Red-tailed Hawk was the most abun- dant Buteo species during the winter, compris- ing 29% of all raptors observed. The lowest count occurred during census 1 (6 sightings) which may have been due to inexperienced observers on the initial count. The 2 highest counts were made during census 7 (26 in- dividuals) and census 10 (28 individuals). Spring migration dates for Red-tailed Hawks in Ken- tucky are not well known, but Mengel (8) states that migrating flocks are seen in February to early March. Present data for census 7 and 10 confirmed the timing of spring migration. Dur- ing census 10, for instance, 6 Red-tailed Hawks were observed soaring in an area of approx- imately 2 km’, in what appeared to be an ag- gregation typical of migrating birds. Red-tailed Hawks generally preferred perch sites along woodlot edges overlooking open areas (12). Madison County habitats are very diverse with plenty of edge habitat; in spite of that, the density was low (0.09/km?, Table 2) when compared with areas in Wisconsin com- prising mostly open habitat, with a probably lower frequency of perch sites (13). In those areas, it may have been higher prey density which favored larger raptor populations: Ring- necked pheasants (Phasianus colchicus), absent in Madison County, were considered an impor- tant prey species in Wisconsin especially when snow provided shelter for small mammals. In addition, Madison County estimates were ob- tained in rolling country with many woodlots; density would therefore, be more easily underestimated than in Wisconsin, where counts were made in open, level terrain with few woodlots (13). Hawk densities generally may be related to availability of perch sites. Relatively low in the plains of Colorado (10), populations reported for Kansas were comparable to those of Madison County; the areas surveyed in Kansas (14) en- compassed a variety of suitable edge habitats such as tree lines along gullies and fields and small stands along stream margins. Rough-legged Hawks, Northern Harriers, Red-shouldered Hawks, Sharp-shinned Hawks, and Cooper’s Hawks were seen in low numbers and together made up 6% of all observations. Northern Harriers and Rough-legged Hawks are found in Madison County primarily during the winter and migrate from the area before the onset of the breeding season (8). Last sightings for both species were made during census 8, which represented the approximate time of northward migration. Both species occurred in Trans. Kentucky Academy of Science — 45(3-4) mean densities of 0.005/km? (Table 2), which is far below estimates obtained for both in Col- orado (10). The Rough-legged Hawk’s southern limit of its main winter range is just north of Kentucky, and low densities were expected (8). Both species prefer open areas for hunting, which may account for their high winter density in Colorado. Craighead and Craighead (6) found that Northern Harriers spent up to 57% of their time perched on the ground, whereas Rough-legged Hawks preferred to perch in lone trees or on telephone poles (15). These species do not require wooded areas and can reach high densities in the plains of Colorado where open spaces and isolated perch sites prevail. Red-shouldered Hawks were present in Madison County in small numbers throughout the winter, the mean density being 0.004 in- dividuals /km/? (Table 2). Densities of this species in other areas are not known; in Madison Coun- ty, they constituted a minor component of the raptor community. Sharp-shinned and Cooper’s Hawk popula- tions (0.0004 and 0.001/km?, respectively, Table 2) were probably grossly underestimated. Both species prefer wooded habitats where they are not easily counted by automobile census. All population estimates must be con- sidered minimum estimates, since some birds were probably obscured by landscape features and buildings, and Northern Harriers, for in- stance, spend much time on the ground where they may not be visible from a car. The hunting ranges of some raptors frequently the study area undoubtedly covered a larger territory than the width of the census strip. A bird hunting outside of the census strip on any given day would have been omitted from the census. ACKNOWLEDGEMENTS Special thanks are extended to those who helped in obtaining field data: R.

RH - Transportation Costs in Kentucky - Smith and Hilton Polynomial Modeling and Predictive Evaluation of Tariff-Derived Transportation Costs in Kentucky Alan D. Smith Coal Mining Administration, College of Business Eastern Kentucky University, Richmond, KY 40475 Charles L. Hilton Department of Business Administration, Eastern Kentucky University Richmond, KY 40475 ABSTRACT The analysis of transportation and distribution costs includes careful and accurate calculation of costs. These calculations include rate studies and their adjustments within a particular location that a company or carrier operates. One approach to this problem is to model physical distribution costs, based on carrier tariffs derived from the National Motor Freight Classification for commodity classes, from selected origin and distribution points to the state of Kentucky. The present study is based on polynomial-surface modeling and spatial analysis, via hypothesis testing and model comparisons of polynomial trend-surfaces, of costs in dollars for 100-pound shipments in commodity classes or ratings of 77.5 and 100. The origin point is Chicago, Illinois, for illustrative purposes, to selected destination points in the state of Kentucky. Significant and predic- tive trends were established, with R’s over 83 per cent of explained variance of spatial-oriented, transportation costs in Kentucky. In general, the generated models and their mathematical expres- sion and error analysis may aid the decision maker in setting realistic prices, based on the predictive trends derived from the tariffs studied. These models may be developed for almost any series of origin and destination points that a particular carrier or user wants to establish, assuming certain data and research design constraints are observed. INTRODUCTION Along with the desire to establish rates associated with transportation costs is the need to classify all articles of commerce in a uniform fashion. The Standard Transportation Com- modity Codes were developed by adhering as closely as possible to the classification system used by the Budget Bureau’s Standard In- dustrial Classification and were initially used by the railroads to accomodate the reporting of carload statistics to the ICC (3). Transportation rates have traditionally been established using two basic factors: ship- ping characteristics of the product and the distance factor, which reflects the amount of miles between origin and destination points. Shipping characteristics have been treated in the Uniform Freight Classification for the railroad industry and the National Motor Freight Classification for the motor carrier in- dustry. Class ratings reflect the proportional dif- ferences in the carrier’s handling of the specific group of commodities - a class rating of 100 commodity would cost proportionally more to handle than a class rating of 77.5. Carrier rates Transportation enterprises are engaged in producing a composite of heterogeneous groups of services for which precise costs cannot be determined. In addition, transportation or physical removal and replacement of com- modities is only one aspect of the total amounts involved in the calculation of physical distribu- tion costs. Physical distribution costs include a large variety of separate and distinct functions that are coordinated together, such as warehousing and related storage, packaging, inventory control, and materials handling. This lack of price control is true for most modes of transport, although the railroads are the most outstanding illustration of this situation (1). Hence, because of the position that the railroads held in the transport structure of this country until relatively recent years, discrimination in some form or another has resulted in the in- tervention of regulatory bodies. However, discriminatory pricing may contain both com- petitive and monopoly elements, and it is very difficult to separate the 2 and give them a quan- titative content (2, 3). Although this is so, it does increase as a funditon of distance, but at an not follow that all discrimination would be overall decreasing Tale: : undesirable and, in fact, it may be necessary for The purpose of this research is to relate the survival. cost of transportation derived from carrier tariffs 132 Transportation Costs in Kentucky — Smith 133 as a function of physical distance, from cen- tralized locations to particular points for model- ing purposes. Hence, by mathematically model- ing, for predictive purposes, establishing general trends and its error evaluation, a managerial decision tool can readily be made available. METHODS The major research tools used in the pre- sent study are polynomial-trend surface analyses, hypothesis testing, and model com- parisons of trend surfaces, generated from com- mercially available computer software, via the line printer (4). Polynomial Trend Surface Analysis and Model Comparisons A trend is a statistically derived surface to explain variations in a given set of values, known as Z-values, that have a given geographic posi- tion, either regularly or irregularly distributed in the x-y plane. The surface is the representation of an equation using the least-squares criterion. This means that the generated surface will be fit- ted to the input data in such a way that the sum of the squared deviations between the data at their particular locations and the corresponding value of the computed surface are minimized. Thus, the least-squares criterion calls for the surface to be laid down in such a way that the sum of the squares of these discrepancies is as small as possible, as indicated by: d* = E, where d’? = deivation squared and E = minimum value. The basic reasoning behind minimizing the sum of squares of the deviations, and not minimizing the sum of the absolute magnitudes of the discrepancies are 1) It is extremely difficult to mathematically deal with the absolute discrepancies or deviations; while the treatment of the squared deviations provides the method of practical mathematical developments in the in- terpretation of the regression equation and 2) Useful and desirable statistical properties follow from using the least-squares criterion (5, 6, 7). The equation describing the surface can be linear (plane), quadratic (paraboloid), cubic (paraboloid with an additional point of inflec- tion), to higher order degree surfaces. In general, the higher the order of the surface, the more the residuals, or individual deviations will be minimized and the more computation will be required. The higher-order trend surfaces may reflect the variation in Z-values more accurately if the study area is complex, but lower-order sur- faces may be more useful in the isolation of local trends. The filtering mechanism allows the up- per limit of variability to be determined by the order of the surface. The equation for a linear trend surface, for example, is: Y = b, + b,X, + b.X,, where Y = dependent variable, b = con- stant value related to the mean of the observa- tions, b,, b, = coefficients, X,, X, = geographic coordinates. This linear equation generates 3 unknowns and 3 equations are needed to deter- mine a solution. These equations are: n n n. (1) 2 Y = bon+b, = X,+b, =X =) i=1 i=l, (2) 8SeX, Vieibyac Xai aX, Geiby. SOX-Xs, and =] i=) i= l= n n n n (3) 2 XiY=bo 2 X,+b, 2 X,X,+b, 2 X. reat i=l evil i=l where n = number of observations or data col- lected. Solving these equations simultaneously will give the coefficients of the best-fitting linear surfaces, where best fit is defined by the least- square criterion. As the degree of the trend- surface that is to be used increases, so does the number of equations that must be solved simultaneously. The significance of a trend or regression may be tested by performing an analysis of variance, which deals with the separation of the total variance of a set of observations into com- ponents with defined sources of variation (8). In trend-surface analysis, the total variance in an independent variable may be divided into the trend itself, which is determined by regression analysis, and the residuals, or error vector. An analysis of variance table can be calculated (Table 1). By reducing the sum of squares, derived from the least-square criterion, an estimate of the variance can be computed by us- ing the F-distribution (8). The F-test, like a t-test, is a very robust test and relatively insen- sitive to violations of the assumptions of random selection of observations and normal distribu- tion of the variables (9, 10). Newman and Fraas (11) and Nunnally (12) looked at a number of in- vestigations that dealt with the F-distribution assumptions and their violation and sum- marized by suggesting that no appreciable effect on the accuracy of the F-test from skewed sam- ple distribution occurred. In addition, if sample sizes are equal, heterogeneity of variance has a negligible effect. 134 Table 1 - Typical Analysis of Variance Table for Polynomial Trend Surfaces.

The F-test for significance of fit is a test of the null hypothesis that the partial regression coefficients are equal to zero and, hence, there is no regression. If the computed F-value ex- ceeds the F-value having a probability of a set alpha level, (7° = 0.01 to 0.05) the null hypothesis is rejected. In polynomial trend- surface analysis, it is customary for in- vestigators to fit a series of successively higher degrees to the data without statistically testing the higher order’s contribution in additional variance. Davis (8) suggested that an analysis of variance table be expanded to analyze the con- tribution of the additional partial regression coefficients to give a measure of the ap- propriateness of each order equation. In regres- sion work, the question often arises as to whether it was worthwhile to include certain terms associated with the order of the polynomial in the model. This question can be investigated by considering the extra portion of the regression sum of squares which arises due to the fact that the terms under consideration were in the model. If this extra sum of squares is significantly large, those terms should be includ- ed. However, if nonsignificant, they are judged unnecessary and should be deleted. For exam- ple, SS (b,/b,) is the extra sum of squares owing to the B,X, term included in a model which otherwise only contained B,. If the F-test in- dicated significance, the model should include the B,X, term. The full versus restricted model principle implies that if the null hypothesis, where H,:B, = 0 were true, and if this condition is imposed on the model, the result would be that contribution of the 3,X, term is zero. This is equivalent to discharging the [3,X, term from the model, resulting in the restricted model. Hence, the restricted model is the model which results when the specific null hypothesis, which is assumed true, is imposed or restricted on the full model. The full model is the model which con- tains all the terms of the lower and higher order Trans. Kentucky Academy of Science — 45(3-4) polynomial coefficients being tested. The sum of squares of the null hypothesis (SS (H,)) is equal to the difference of the regression sum of squares of the full less the regression sum of squares of the restricted model. Also, the degrees of freedom of the null hypothesis (df (H,)) is simply the difference between the degrees of freedom of the full and restricted models. Study Area For illustrative purposes, motor carrier transportation costs were computed using com- modity classes 77.5 and 100 at the 100 pounds of shipment weight and were selected from an origin point in Chicago, Illinois to destination points in or around Kentucky (Table 2). The costs are in dollars, per 100 pounds of shipment weight. Table 2. Transportation Costs for Classes 77.5 and 100 from Chicago, Illinois to Selected Points in or around Kentucky.

All costs, for both commodity classes 77.5 and 100 were derived from tariffs for 100 pounds of ship- ment weight. The 79 data points were estab- lished by selecting points in a straight-line fashion across the state of Kentucky at approx- imately 20-30 mile-wide bands. Next, the associated transportation costs from Chicago, Illinois, were determined and used as the initial data base, along with spatial coordinates, in the development of the mathematical models. Each destination point was recorded and trend sur- face analysis techniques, via SYMAP (13) anda computer program suggested by Smith (14), were performed. RESULTS AND DISCUSSION Tables 3 and 4 illustrate the mechanics and results of the hypothesis testing and model com- parisons of polynomial trend surfaces in predict- ng transportation costs to the state of Kentucky for the commodity classes 77.5 and 100, as well as the differences in changes for the various classes. Table 3 shows the hypothesis testing and modeling comparison results, in traditional analysis of variance (ANOVA) format, to deter- mine if the third-degree, polynomial trend sur- face of classes 77.5 and 100 differences, from Chicago, Illinois to selected points of destination in Kentucky, accounted for enough explained variance in predicting its spatial distribution over random variation or no trend. The variance accounted for by the third-order surface was substantial (R? = 75.20) and was found to be highly significant (p = 0.0000). Table 4 sum- marizes the same basic information found in Table 3, but restates it in standard multiple linear regression (MLR) terminology. As shown in Table 4, a summary of the F-ratios, prob- ability levels, R? for both the full and restricted models, degrees of freedom-numerator, degrees of freedom-denominator, and _ statistical significance for each trend surface is presented. As evident from a quick inspection of the table, the costs for the two commodity classes studied from Chicago, Illinois to location coordinates in Kentucky, similar results were not evident. Although both the sixth-degree, polynomial trends were found to account for a statistically significant amount of explained variance (R? for 77.5 was 83.03 per cent, and R? for class 100 was 83.03 per cent as well, representing a constant and proportionate difference in the costs for the two commodity classes), the sixth-degree sur- face was not found to be statistically the best fit, since it did not account for enough variance for the lower-degree surfaces. the second-order sur- face was found to be best fit (R? = 75.89 per cent, p = 0.0000). 136 Trans.

The models aid the decision maker in setting realistic prices, based on these tariffs, and may be established for almost any series of origin and destination points that a particular company or user may be interested in, provided certain data and research design constraints are observed. The major benefit of modeling research is to be able to parameterize the actual distributions of important parameters associated with physical distribution costs. Examples illustrated in this research allow the user to mathematical- ly portray selected distributions of parameters in order to take administrative measures in the future to establish reasonable pricing structures. This process can bring the business ad- ministrator’s “common sense” and judgement into play to determine the best fit. With the in- creasing use and availability of appropriate soft- ware and hardware, computer modeling should be used in conjunction with statistical models in estimating the usefulness and limitations of trend-surface analyses for predictive purposes in generating models with geographic dimensions.

Corn earworm infestation was simulated (S-CEW) by stabbing the ear through the husk with a knife blade, and this also served to inoculate the kernels with high aflatoxin producing strains of A. parasiticus (NRRL 2999) and A. flavus (NRRL 3251). European corn borer (ECB) was introduced as egg masses and maize weevils (MW) were introduced as adults. All treatments were introduced singly or in combinations. Rainfall was adequate during the 1982 grow- ing season but drought conditions prevailed during 1983. The highest levels of aflatoxin occurred generally in treatments involving insects or their combinations plus either species of the fungi. In 1983, very high levels of aflatoxin were attributable to the drought stressed corn. A mean production of >54,000 ppb total aflatoxin was elicited from the ECB, S-CEW plus NRRL 2999 and MW combina- tion compared with >24,000 ppb when NRRL 3251 was inoculated instead of NRRL 2999. The untreated control produced a mean of >2,500 ppb aflatoxin in 1983 compared to a mean of 1 ppb in 1982. INTRODUCTION loss from feeding such corn.

Research in this area has progressed rapidly and a regional aflatoxin sym- posium involving the southeastern states was held in 1982 to review and report findings (4). The role of arthropods in field contamina- tion of Aspergillus flavus in corn was thoroughly reviewed at the above symposium (5). Our research has also examined the role of insects and mites in A. flavus dissemination and conuomitantly the effect of mycotoxins on the arthropod (6, 7, 8). The objectives in the work reported here were to examine the influence that some selected insects such as the European corn borer, Ostrinia nubilalis (Hubner), maize weevil, Sitophilus zeamais Motschulsky, and corn ear- worm, Heliothis zea (Boddie) may exert in com- bined effects of dissemination, and infection of A. flavus and production of aflatoxins under Kentucky conditions. Concomitantly, it was our objective to determine the possible additive effects of plant stress, introduced to the corn plant by the European corn borer, on alfatoxin production. MATERIALS AND METHODS GENERAL METHODS. Corn hybrids were planted in 6 replications of a randomized block design with each plot having 20 plants minimum. Four European corn borer (ECB) egg masses were introduced per plant by placement on the leaf immediately beneath the ear at beginning silk and again 3-4 days later. Simulated corn earworm (S-CEW) injury was via a knife wound made by a stab (ca. 3 cm long) about mid-ear, longitudinally through the husk, and this also served to in- troduce fungal spores to the ear. The fungi were originally obtained from the USDA Northern Regional Research Laboratory, Peoria, IL. Aspergillus parasiticus NRRL 2999, a heavy G aflatoxin producer, and A. flavus NRRL 3251, a heavy B aflatoxin producer, were inoculated by dipping the knife blade tip into the inoculum, which was standardized to provide a spore count of ca. 2.5 x 10° spores/ml. Inoculation was generally done 15 days after 50% pollination had occurred. Maize weevil (MW) were introduced onto the ear by pulling the husk tip down slightly and placing the weevils on the kernels and then closing the husk and securing with a rubber band. MW adults were randomly selected from a mixed population and placed on established Aspergillus cultures of NRRL 2999 and NRRL 3251, and allowed to become contaminated overnight. Five MW adults were then introduced to each ear. Uncontaminated weevils were used as a check. All treatments were made singly or in combination with other treatments (Tables 1-3). The untreated control plants were allowed to grow undisturbed to maturity/harvest. All plots were protected from bird damage by cap- ping the ear with a plastic screen mesh bag. Ears were harvested by hand and placed in nylon net bags for oven drying; this was done for 1 wk at 38°C, lowering the moisture to ca. 13 percent. The ears were then hand-shelled, ground in a Stein mill, the 20-ear sample was split to ca. 1/16 of the original sample, and weighted into a tared bottle. Table 1.

The Quicksand treatments are listed in Table 2 and were administered according to procedures described above. The Lexington treatments included MW in- troductions which were not made at Quicksand (Table 3). 1983 Studies — The experimental design for the 1983 growing season varied from the previous year in that one corn hybrid (Pioneer 3369A) was planted only at the South farm of the Kentucky Agricultural Experiment Station in Lexington. ECB egg masses were introduced to coincide with first generation moth flight on June 16-21, when the corn plants were ca. 0.5m high, while the second generation introduction was made at beginning silk. All other treatment procedures followed those outlined in the general test methods and are listed in Table 1. A corollary experiment was performed to study the effect of kernel maturity on aflatoxin production when exposed to A. flavus (NRRL 3251), S-CEW and MW. Five adult MW’s were introduced to each ear at 7, 15, 28 and 35 days after 50% pollination had occurred. The samples were harvested and prepared for aflatoxin analysis as described previously. RESULTS AND DISCUSSION The growing season in 1982 was considered “normal”; precipitation was adequate at both experimental fields in Quicksand and Lexington. Hence, stress factors from abiotic sources were generally absent. In reviewing the conditions leading to fungal invasion of corn kernels with A. flavus, Hesseltine (9) enumerated spore inocula quantity, stress factors on the growing plant, insect and mite populations, damage from other fungi, varietal susceptibility or resistance, mechanical damage from farming, storm damage, bird damage, mineral nutrition of the plant, and temperature. Our experimental method involved stressing the growing plant and developing ear with European corn borer (ECB, via inoculation with egg masses), maize Insects and aflatoxin in Kentucky corn — Rodriquez et al. 141 weevil (MW) and corn earworm (S-CEW, via simulation by knife wound). Analyses of the aflatoxins confirmed earlier results demonstrating the high aflatoxin produc- ing characteristics of the NRRL 2999 and NRRL 3251 strains (8). Also, the results pointed up the especially high productivity of aflatoxin G, and total aflatoxin by NRRL 2999 (Tables 2-6). Again, this characteristic had been demonstrated earlier (8). In 1982, the Quicksand experiment showed that ECB combined with NRRL 2999 introduced via S-CEW produced the highest levels of B,, B,, G,, and G, aflatoxins, but only in the G, type was this level significant from the second highest level produced (Table 2). The ECB plus NRRL 2999 with S-CEW treat- ment also elicited production of the second highest level of the B and G aflatoxins at the Lexington planting, being outproduced only by the MW with NRRL 2999 treatment. The dif- ference, however, was not significant (Table 3). ECB alone did not prove to be significantly dif- ferent than the untreated control, producing only traces of aflatoxin at either location (Tables 2 and 3). The S-CEW treatment alone promoted significantly higher levels of B,, B, and total aflatoxin than ECB, or untreated control at Quicksand (Table 2) but not at Lexington (Table 3). At Lexington, when MW was introduced in several treatments, it played an important role in influencing aflatoxin production. MW plus NRRL 2999 produced the highest level of total aflatoxin, while ECB plus S-CEW with NRRL 2999, S-CEW with NRRL 2999, and MW plus NRRL 3251 followed in that order. MW alone, however, proved to influence only low level aflatoxin production (Table 3). Hybrid effect was significant and this was borne out at both locations, with FRM017xT232 giving a_ significantly higher level of total aflatoxin than Cl66xFR802W (Tables 2, 3). This difference, however, should be viewed from the perspective of relative magnitude, and it is ap- parent that this is not large enough to have a significant impact in host plant resistance towards Aspergillus contamination/aflatoxin production. Consequently, we accept the find- ings that neither hybrid offers genetic sources of aflatoxin resistance. Because of this, Pioneer 3369A was planted in 1983, not only in Kentucky, but in other southern states as part of a regional study. The summer of 1983 was extremely dry except for the early one-third of the growing season, and the planting at the South Farm in Lexington was under great water stress. Harvest yield in the experimental field was estimated as being ca. 40 percent of normal (Avg. corn yield for Fayette County was estimated at 32 bu/A. by Kentucky Crop and Livestock Reporting Ser- vice, compared to 105 bu/A. in 1981). Aspergillus infection was readily evident at harvest, and unusually high levels of aflatoxin were produced in all treatments, including the control plots (Table 4). This was attributable to the stressed condition of the growing plant and preharvest corn. The highest levels were found in the treatments involving insects, i.e., ECB, MW, and S-CEW, or their combinations plus either species of the fungi. A mean production of 54,330 ppb total aflatoxin was encountered from the ECB (2nd gen.), S-CEW plus NRRL 2999 and MW (treatment no. 14), compared with 24,760 ppb when NRRL 3251 (treatment no. 15) was substituted for NRRL 2999 (Tables 4, 6). The untreated control produced 2,560 ppb, com- pared to a mean of 1 ppb in 1982. The insects, or their combinations, contaminated with Aspergillus, generally resulted in significantly higher levels of total aflatoxin than the treatments introducing insects without fungi, or the untreated control. The only exception was the ECB, Ist and 2nd generation, treatment no. 6 (Tables 1, 4). 142 Table 4. Treatment effect: Aflatoxin analyses of corn hybrid grown at South Farm, Lexington, Kentucky, 1983.

In conclusion, the effect of drought in 1983 on aflatoxin production in corn was dramatic as compared with more normal years, and clearly demonstrated that while insect interaction also increased the aflatoxin levels drastically, basically the plant has to be physiologically disposed/stressed to provide the correct am- biance for fungal synthesis of mycotoxin (10). The possibility of Kentucky corn carrying relatively large loads of aflatoxin in the 1983 crop was great. If our untreated control plots were any indication of the condition of the 1983 crop generally, the aflatoxin level exceeded the FDA permitted levels of 20 ppb by a factor of more than 100 x.

RH - Mine Roofs in West Virginia — Smith Borehold Determination of Immediate Lithologic Characteristics of Adjacent Stable and Unstable Coal Mine Roofs Alan D. Smith Coal Mining Administration, College of Business, Eastern Kentucky University Richmond, Kentucky 40475 ABSTRACT An in-depth study of 4 adjacent mine crosscuts, 2 of which juxtaposed a major beltway, in an underground coal mine located in the Northern Appalachian Coal Field, northeastern West Virginia, was completed to determine if lithologic and geologic parameters of the immediate roof strata could be used to differentiate roof conditions. Three of the crosscuts were extremely unstable and, if they had not been bolted and reinforced with a series of wooden cribs, would have, in most probability, failed. The stable crosscut, which showed no sign of deterioration, is flanked by the unstable areas and is supported by the traditional roof-bolt techniques and patterns common to the Appalachian Coal Field. A study, using diamond coring, borescoping, and X-ray diffraction techni- ques, was completed. All cores from 4 sites had primarily dark gray shales (124), hard sandstones with rippled shale streaks (563 RIP), and dark gray shales with interbedded sand, rippled sandstone streaks (322 RIP) as the dominant lithologies. The stable crosscut appeared to contain slightly more massive strata of the 322 RIP and 564 lithologies. Drill site 4, classified as extremely unstable, witha previously recorded major roof fall on the belt a few meters away, had evidence of expandable montmorillonite-illite, mixed-layer clay minerals. No evidence of these clay minerals was observed in the stable crosscut. However, the evidence collected does not clearly differentiate among adjacent stable and unstable immediate mine roof profiles; hence, more complex geological and mechanical interactions must be in play to account for the extreme changes in mine-roof quality.

Frequently, mine roof strata will contain geologic and _ lithologic features that will eventually cause roof failure. Unfortunately these features are not readily identified until after the failure has occurred. The purpose of any comprehensive monitoring program for ground control should be to identify potentially unstable roof strata soon after coal extraction. This enables the mining engineer to take preventive measures before roof con- vergence becomes uncontrollable and complete failure is likely. According to research completed by Van Besien (3) in underground mines of the western United States, many roof falls are associated with localized defects in the immediate roof. Factors contributing to roof falls include the type and thickness of the rock strata, slickensides, plant material on bedding planes, burrowed and rotted zones, rider coal seams, kettle bottoms, cracks in the roof, and the presence of water. Dougherty (4) found in his study that roof falls occurred 7 per cent of the time when the roof was sandstone, and 12 per cent of the time when coal was left to protect the shales, while 80 percent of roof falls occurred when the roof consisted of unprotected shales. The best quality roof strata generally con- sists of well consolidated graywacke sandstone which are generally about 10 feet thick and laterally continuous for more than 2000 feet (5). However, sandstones also present roof control problems. Orthoquartzitic sandstones may pro- vide high quality roof rock needed, but this sandstone tends to react more brittely than other sandstones or non sandstones (6, 7). Usually orthoquartzitic sandstones are jointed and fractured producing the possibility of a severe roof fall (5). In roofs where interbedded sandstones and shales or flaggy sandstones exist, roof com- petence depends on bed thickness (5, 7). When beds are less than 2 feet thick, separation can occur along the bedding plane giving rise to a roof fall that can fall as a single unit. If beds become thicker than 10 feet, slickenside sur- faces develop due to differential compaction giv- ing rise to roof falls that may not fall as single units. Tiylveri’s (3) study also indicates that lithified plant material on bedding lanes is likely to contribute to the incidence of roof falls, because it weakens the cohesiveness of the rock to the next bed. Therefore, the optimum bed thickness is 2 to 10 feet thick producing an optimum bridging strength of the material. Discontinuous sandstone bodies, such as sandstone channels, often rank as one of the more troublesome roof control problems (6, 8). These bodies also frequently cut out coal beds, are involved in roof falls, and can start water problems. The associated problems with discon- tinuous sandstones are due to the abrupt change of lithologies, such as the change from shale and standstone, and the differential compaction of sediments along the boundary of the sand- stone deposit. These 2 factors create the shears and/or slumps which cause natural zones of weakness and excellent places for roof control problems to develop (7, 9). The field techniques to recognize these problem areas may include the presence of fractures and/or steeply dipping coal beds, slickenside surfaces becoming more numerous, and the observation of a rise in the floor elevation (8, 10). However, the occurrence of sandstone channels is at best difficult to predict. Studies by Hylbert (7) and Lagather (11), found that thick shale roofs are often characterized by laminated shales, usually coarsening upward to a rider coal seam. Roofs such as these are hazardous because laminated shales tend to separate along bedding planes. Sudden changes in the thickness of shales by either pinchouts or wedging of sediments are sometimes associated with roof falls. Heavily burrowed shales or siltstones present potential roof control problems. The strength of these fine-grained rocks is reduced by burrowing. Supporting burrowed roof rock by bolting is difficult, if not impossible, due to the nonbeaming support nature of the burrowed rock. Rooted shales and siltstones are another roof control problem with engineering problems similar to burrowed shales. Roots penetrating these rocks often show slickenslides intersecting at angles of 90 to 120 degrees (12). Rooting weakens the rock making bolting to form the roof beam difficult and sometimes impossible. The occurrence of rider coal seams has been found to have a definite influence on roof stability (7, 9). Hylbert (7) and Horne et al. (5) found that rider coal seams and their associated root zones represent incompetent layers. Rider seams have their worst effects when they are within 6.1 m of the coal seam being mined. It is at the interface between the rider seam and the adjacent roof rock where separation of the strata may occur, causing a mine roof fall. The fall usually begins at the coal seam and falls to the above rider seam. If a higher concentration of water is present along the separation, this 146 Trans. Kentucky Academy of Science — 45(3-4) may weaken the ability of the roof to support a load, making roof instability a greater likeliood. Although the design of a safe mine roof can be quite complex, challenging, and in need of constant surveillance, generally crude and relatively unsophisticated equipment is used to install and to monitor mine roof conditions. Of course, this situation is probably due to the expensive and possible delicate nature of the more advanced eqduiprnent (13). In addition, there is usually some resistance to the interfac- ing of new applications and techniques into the underground coal mining environment by min- ing personnel, primarily due to tradition and routine of daily operations. The monitor equip- ment is generally costly, for example a relatively simple optical borescope with a 6 to 9 m cable extension may easily result in a $10,000 to $20,000 expense, depending on the model and attachments. Generally, some training by a specialist is needed for interpretation. The purpose of the present research is to evaluate the monitoring value of both adjacent unstable and stable mine roof top in a coal mine in the Appalachian Coal Field to determine if detailed borehole scoping, diamond drilling and associated coring, lithologic classification, and dimensional analyses can significantly enhance roof quality assessments. Results from borescope inspection can correlate, in practice, very well with diamond-drill core logs and help resolve the question whether a fracture is the original or resulted from stress induced during the drilling process. The detection and assess- rosscut 13 ment of immediate roof characteristics, if significant, may be monitored in the future through various stations in coal mines, usually during the roof bolting operation to differentiate potentially stable and unstable mine roof conditions in order to estimate proper and cost effective support systems. METHODS STUDY AREA The Upper Freeport coal seam in the mine studied averages about 9 ft. (2.7 m) thick with a variable parting of siltstone and bone thickness from 2.5 ft (0.8 m) to small fractions of an inch. The coal, relatively high in sulfur content which frequently staines the powered limestone utilized in the rock dusting process. A site was chosen to investigate the adjacent stable and unstable areas in the immediate roof in this coal mine in northeastern West Virginia, owned and operated by Island Creek Coal Company. A total of 4 locations were marked and measured, as illustrated in Fig. 1. The lithology of the immediate mine roof consisted of primarily shales. As can be seen in Fig. 1, entry spans ad- jacent to the roof falls and/or unstable areas are not significantly different precluding differential loading from overburden as a_ contribution factor in these failures.

Mine Roofs in West Virginia — Smith 147 SAMPLING AND BORESCOPING TECHNIQUES Diamond drill holes of 2 in. (5.1 cm) diameter resulting in an approximately 0.88 in. (2.2 cm) diameter solid core were completed to varying depths in the immediate mine roof tops in the 4 sites portrayed in Fig. 1. A hydraulic pump was used in connection with the portable drill rig to retrieve the cores. Only water without the benefit of bentonite was used as the drilling fluid. The drill apparatus was _ sufficiently anchored below the mine floor and above on the mine roof with hydraulic compression rams; in addition a safety chain was used near adjacent wooden cribs to provide an extra margin of safe- ty. A post for safety purposes was always erected near the drilling site and immediately over the hydraulic control box. The cores derived from the drilling of the various sites were boxed, short notes concerning speed of drilling, core recoveries, and lithologic classification, accord- ing to Ferm and Weisenfluh’s code system (14) were recorded and tabulated (Table 1). Some of the samples from drill site 4 underwent X-ray dif- fraction to identify the clay minerals present. These samples were selected because of the intermittent water flow characteristics they exhibited during drilling, which may be caused by expandable mixed-layered clays. Finally, standard borescope analysis techniques were employed to locate fractures and gross lithologic changes in the 4 drill sites. Tabie 1.

Drill fluid leaked out through the shale and sandstone sequences toward the exposed roof fall over the belt and flowed out by the bolt header boards. However, this condition was stopped a few weeks later due to the expansive nature of the clay derived from drilling into the shale. DISCUSSION CORING AND BOREHOLE SCOPING OF DRILL SITES 1 THROUGH 4 Presented in Fig. 2 and Table 3 are the data derived from coring and optical borescoping of drill locations 1 through 4. Due to the relatively poor core recovery of drill site 1 (Table 2), the lithologies of the first few meters are relatively uncertain and extrapolated from the other cores and borescope data. Basically, strata in the dia- mond cores can be characterized using three lithologic types: 124 (dark gray shale), 563 RIP (hard sandstone with rippled shale streaks), and 322 RIP (dark gray shale of sandy content with interbedded, rippled sandstone streaks). These lithologies are relatively consistent throughout the cores, for both the stable (drill site 2 and unstable (drill sites 1, 3, and 4) areas. The stable roof strata appears, however, to contain a more massive section of 322 RIP and 564 lithologies that are closer to the initially cut roof top, but the variability of lithologies of the adjacent unstable immediate roof beds are relatively high; and, thus, may make this observation invalid.

The borehole scoping results (Table 3) prove to be even more inclusive, especially in light of the fact that some measurable con- vergence has occurred in the unstable areas (drill sites 1, 3, and 4) and fracture zones are expected. The stable crosscut (drill site 2) hada noticeable open crack at approximately 5.2 ft. (1.6 m). However, this same crack, which may have led to the development of fracture zones characterized in the other drill sites, is also represented in the unstable roof top as well. This presence of cracks at this depth into the roof is puzzling, especially since this stable crosscut is flanked by unstable roof tops (Fig. 1).

X-RAY DIFFRACTION OF DRILL SITE 4 It is difficult to make quantitative deter- minations at mixed-layered silicate structures particularly when layers of the different silicate minerals are interstratified. Figure 3 ABC display X-ray diffractograms of clay sampled from drillhole site 4. As illustrated in Fig. 3, parts A through C, which represent different treatments, some recognizable peaks for qualitative interpretation are evident in the defractogram, using a copper-target element. The quartz peak, represented by the characteristic diffraction of 26.7 20 angle, ap- Mine Roofs in West Virginia — Smith 151 pears in all the diffractograms. Standard preparation techniques, as outlined by Cullity (15), Grim (16), and Mitchell (15), using the powdered method of preparation, in which a small sample, giving particles of all possible orientations is placed in a collimated beam of parallel X-rays. As portrayed in Fig. 10A, an untreated powered sample was exposed to X-rays and, based on the basal spacing deter- mined from the first order reflections, kaolinite (12.35 20 angle, d or basal spacing equal to 7.19 A), and illite (8.8 20 angle, d equal to 10.0 A) can be identified. However, to identify _ illite- montomorillonite mixed-layered clays is more difficult, as previously mentioned. Since mont- morillonite is characterized by extensive isomophoric substitution, it has a high cation exchange capacity (10-15 times that of kaolinite), causing water molecules and other cations to be attracted between crystal units. This attraction results in expansion of the crystalline lattice, high plasticity, and cohesion properties. Based on these properties, by a com- bination of glycolation and heating treatments, illite-montmorillonite qualitative identifications can be made (Fig. 3 B-C). However, quantitative determinations of the amounts of the different minerals in the clay sample taken from drill hole site 4 on the basis of simple comparison of dif- fraction peak heights or areas cannot be made. The reasons for this inability to differentiate the exact amounts of illite and montmorillonite in- volve the differences in mass absdorption coeffi- A 26.7 cients of different minerals, in particle orienta- tions, in same weights, in surface texture of the powdered sample, in crystallinity in the minerals, in hydration, as well as other factors (17). As shown in Fig. 3C, the prominant feature of this diffractogram is the reduction of the kaolinite peak and a sharpening of a mixed- layer montomorillonite-illite peak at about 13.6 ; also evident is the illite peak remaining unchanged, as well as the quartz peak. Although a quantitative analysis is complex, as suggested by Moore (18) and Buck (19), a semi- quantitative analysis can be attempted. The montomorillonite peak is usually small on the diffractogram and, when found in conjunction with illite, may be up to a multiple of 7 of that peak actually recorded in the diffractogram compared to the illite recorded peak (15, 17, 18). Therefore, there could be theoretically a 1:1 relationship of illite to montmorillonite, when comparing the two peaks. Although the diffrac- togram indicates the possible presence of small amounts of montmorillonite, the amount could be significant and, due to its great expansive properties, be a major contributor to mine roof instability. The clay samples were derived from a depth of approximately 1.5 meters (4.8 ft.) into the roof in the 124 coded lithology. In addition, although further tests were not completed due to sampling constraints, similar clay appeared to be present in the relatively unstable drill site 1. However, no evidence of this clay forming dur- ing the drilling operation was found in site 2. 12.35 BLK 12.35 Trans. Kentucky Academy of Science — 45(3-4) 152 aos 12.35 3.

CONCLUSION The results of this study of adjacent stable and unstable immediate mine roofs creates more questions than it solves. Although it ap- pears that the expansive nature of the montmorillonite-illite clay mixtures may be a potential cause in the unstable areas, it does not explain the origin of the source of water or addi- tional cations available to these clays, causing subsequent swelling behavior. The lithologies associated with the clays, especially the in- terbedded shales and sandstones, and fractures found may act as a conduit for subsurface flow, but these lithologies are associated, according to the cores, with the stable area as well. In- deed, an open crack, according to the borescop- ing data, was also found in the stable area that could allow for this directional water flow, although no expandable clay was observed dur- ing drilling. Generally, the present study il- lustrated in this case that the immediate lithologic and geologic features corresponding with the stable and unstable area were not clear- ly different or predictable, in order to base a design approach for ground control in the development of stable entries for the affected coal mine. Hence, other than the results of the X-ray diffraction and identification of expansive layer silicates, many, if not most, mine roof falls occur under a complex set of conditions and subsequent interactions that frequently can not be forecasted on the basis of geological and lithological evidence alone. However, many potential roof problems can be successfully predicted geologically using conventional rock coring and field reconniaissance. The designing of ground control systems must be _inter- disciplinary in nature, as presented in this study, based on probability of occurrence.

RH - Notes NOTES Break Angle Determination and Con- touring of Coal Mine Roof Falls: Sug- gested Methods and Case Study. —Geometry of mine roof falls and _ their associated break angles of the strata involved are basic input into many rock mechanics, ground control techniques, and mine-roof fall prevention programs (Karhnak, 1981, An over- view of Bureau of Mines ground control research, In Proc. of First Annual Conf. on Ground Control in Mining, Peng (ed.), West Virginia Univ., Morgantown, WV; Obert and Duvall, 1967, Rock mechanics and the design of structures in rock, John Wiley and Sons, Inc., New York; Peng, 1978, Coal Mine Ground Con- trol, John Wiley and Sons, Inc., New York). The geometry of mine-roof falls depends on the lithologic characteristics, strata stresses, pro- gressive failure characteristics, time duration of opening, moisture contents, and degree of com- petency of the mine-roof beds. A suggested method for gathering basic information for the determination of break angles and the eventual plotting of the basic geometry of mine roof falls was established. The technique for data collec- tion is relatively simple and involves only 15 to 45 minutes to complete, depending on the com- OUTBY crosscut 19 IBELTWAY crosscut 20 Figure 1. ae} Planametric view presenting the location of the coal mine roof fall measured and contoured. plexity and areal extent of the fall and the experience of the researchers. The only equip- ment required specifically for this procedure are string, a small wooden base station with 22.5 degree intervals marked on the side facing up, and an extendable measuring pole to reach the various horizontal strata involved. The mine-roof fall was mapped, for il- lustrative purposes, in a coal mine in the Appalachian coal fields located in Bayer, West Virginia. Figure 1 outlines the basic location of the mine roof fall: between the 19th and 20th break or crosscuts inby (inby refers to the direc- tion towards the working face or away from the mine shaft) in 3-Left submain entry. The base station is located 16.7 ft. (5.1m) from the mid- section of the crosscut facing the belt entry and the farthest extent to the east of the roofline is 23.3 ft. (7.1 m) from the edge of the 19th break, as shown in the figure. The O-degree interval pointed due east or directly outby (outby refers to the direction towards the mine shaft or away from the mine working face) and the rest of the readings are located in relation to that origin point. Figure 2 is the result of plotting the infor- mation found in Table 1 and portrays the elongated geometry of each strata break 18.211155m.) Final geometrics of coal mine roof fall. Note that the contour interval between strata break horizons are not constant, see Table 1 for more specific information. 154 Notes horizontal. Of course, it must be remembered that an individual break horizon may be com- posed of several separate and/or interbedded lithologies. Finally, Table 2 summarizes the break angles of each series of horizons and can be used to compare symmetry of the fall. As evi- dent in Table 2, the mean break angle for all strata horizons in the outby direction was 41.4° (o = 16.98), the mean break angle in the inby 155 direction was 61.1° (o=15.97), the average break angle facing north was 66.5° (o = 14.03), and the average break angle of the mine roof fall facing directly south was 51.4° (c= 15.01). However, its most useful function would be to compare break angles of other falls in the area to the major stress axes to determine if direction of insitu stress was a major determiner of mine- roof falls.

The letters in parentheses next to the orientations of the base stations symbol basic direction, where east represents the mine inby direction and west represents the outby direction. The symbols H and V represent horizontal distance from the base station to the perpendicular dropped directly from the strata break horizon and the vertical distance to each break horizon, respectively. @ Denotes that the roof edge or roof line is 9.5 ft. (2.9 m) above the mine floor. As evident from the break angles listed in Table 2 and the roof fall diagram of Figure 2, the steepest angles are associated with the N-S direction, probably due to the cutter-roof forma- tion along the ribs. Large amounts of stress con- centrate along the ribs, causing brittle rupture of roof rock at steeper break angles, which may approach near vertical break angle measurements. In addition, the NW-SE elongaton of break angles may be in line with the major axis of the strain ellipsoid, which may give an indication of major stress direction. In the Appalachian Coal Fields, this direction has been generally measured in a NE-SW direction. Since the major stress and strain axes run perpendicular to each other, the geometry of the fall, if controlled by stress-release mechanisms instead of the lithologic character of the roof, appears to provide additional evidence for the NE-SW direction of the major stress axis. 156 Trans.

The break angles approaching near vertical slopes close to the north-south direction may be the result of cutter-roof forming along the entry ribs. @ Sample calculation using the following formula: slope = arctan AV AH/AH where: H = change in horizontal direction from base station, V = change in vertical direction from floor to strata horizon. For example, from Table 1, the change in horizontal distance for 337.5 degrees reading is 8.33-5.42, and the change in vertical distance is 3.67 - 2.08. The arctan of 1.59/2.91 gives a break angle of 28.7 degrees. b Break angle greater than 90 degrees, assumed to be vertical. Roof control is a never-ending task, not only at the working face and in sections where miners are working, but along haulways and air- ways that must be kept open. As coal is being excavated, the stresses that are set up and pro- gressively changing in the roof result in fractures and movements that are very difficult if not presently impossible to detect, and may lead to mine-roof falls. The measurement of pre- existing and newly developed falls, through break angle determination and contouring of basic geometrics may add needed data for the establishment of statistical relationships with failure parameters associated with mine roof falls and eventually develop predictive and preventative techniques for mine ground control in underground mining operations.—Alan D.

Experimental Transplants of Plerocercoids of Triaenophorus crassus Forel into the Body Cavity of Whitefish, Coregonus clupeaformis (Mitchill). —Triaenophorus crassus is a pseudophyllidean tapeworm whose plerocercoid larva is found in the muscles of a variety of salmonid fish. Normally, the parasite occupies the host body cavity only during the first week of infection before migrating from the fish digestive system to the muscles (Rosen and Dick, Can. J. Zool. 62:203-211, 1984). Recently, experimental infec- tions of whitefish fry, Coregonus clupeaformis (Rosen and Dick, Can. J. Zool. 62:203-211, 1984), and rainbow trout fry, Salmo gairdneri (Rosen and Dick, J. Wild. Dis. 20:34-38, 1984), with T. crassus resulted in a small number of incompletely differentiated plerocercoids that reentered the body cavity from the muscles between days 40-60 postinfection (PI) and survived in this site. Considerable pathology, in- cluding hemorrhaging and granuloma forma- tion, was associated with these plerocercoids in the body cavity. It is not known whether fully differentiated plerocercoids (i.e., worms with hooks and at least 3 months old) contained in a host capsule may reenter the body cavity of fish, but several worms with hooks have been observed to penetrate through the host capsule within the muscles of whitefish (Rosen and Dick, Can. J. Zool. 62:203-211, 1984). These worms may represent a long-term source of parasites capable of reentering the body cavity since they may live 4 to 5 years in muscles (Miller, Bull. Fish. Res. Board Can. No. 95, 1952). It is impor- tant to determine whether these fully differen- tiated plerocercoids of T. crassus may also sur- vive upon reentry into the host body cavity if the pathology in fish caused by this parasite is to be accurately assessed. The objective of this study was to determine whether or not T. crassus plerocercoids can survive in the body cavity of whitefish if they are introduced into this site after they are completely differentiated and encapsulated by the host. RH - Notes Fully formed plerocercoids of T. crassus were removed from capsules in the muscles of cisco, Coregonus artedii, obtained from Quigly Lake, Manitoba (54°51’N, 101°04’W). Plerocer- coids (4-5/fish) of unknown age were pipetted into the body cavity through an incision made in the ventral hypaxial muscles of nine 4-5 year old laboratory reared whitefish packed in ice and anesthetized with MS-222. The incision was then closed with catgut chromic 310 USP (B. Broun Melsungen A. G., W. Germany), and the revived fish were held in 12°C aerated water. Fish were sacrificed at weekly intervals starting at day 7 PI. Plerocercoids and associated host tissues were removed from the body cavity, placed in a 0.75% salt solution and observed with a Wild M-3 dissecting microscope. Some worms and tissues were then fixed in Bouin’s solution, routinely processed for paraffin embed- ding, sectioned at 10mM and stained with hematoxylin and eosin. All plerocercoids recovered from the transplants were dead. Worms were stretched along the length of the body cavity or entwined around viscera. Most plerocercoids were com- pletely surrounded by connective tissue at day 28 PI, and all were in a state of degeneration. These results clearly show that plerocer- coids of T. crassus have the capacity to survive in the body cavity of whitefish only if they reenter this site from the muscles prior to the completion of their development and encapsula- tion by the host. Therefore, the pathology associated with plerocercoids of T. crassus in the body cavity of whitefish must originate dur- ing the two month migratory phase of develop- ing plerocercoids prior to their encapsulation.

Dawson Springs Seep Swamp: Site of Some Significant New Amphibian Records.— Dawson Springs Seep Swamp is a privately owned, forested Sphagnum swamp located in the floodplain of Montgomery Creek near its confluence with the Tradewater River, Caldwell County, Kentucky. Its geological and ecological features were described by Quarter- man and Powell (Potential ecological/ geological tandmarks of the Interior Low | Plateaus, U.S. Dept. Int., Nat. Pk. Serv., 1978), and Harker et al. (Western Kentucky Coal Field: 157 preliminary investigations of natural features and cultural resources. Vol. I, Part II, Technical Report., Ky. Nature Preserves Comm., Frankfort, 1980) conducted aquatic and ter- restrial surveys of the site’s flora and fauna. The purpose of this note is to augment the biological findings of these studies and to present new Ken- tucky distributional data for three species of am- phibians whose ranges in western Kentucky are poorly understood. Specimens cited are in the Austin Peay State University Museum of Zoology (Nos. 3487 to 3491). Two visits were made to the swamp, 7 June 1983, and 24 February 1984. On both occasions the area was thoroughly searched for amphib- ians by looking under rocks, logs, leaf litter and Sphagnum. During the first visit, 2 Pseudotriton montanus (snout-vent lengths 65 mm and 57 mm) and Rana sylvatica (snout-vent length 50 mm) were taken. All were found under rocks at the edge of a spring located at the base of a low sandstone bluff which borders the swamp. On the second visit, 2 P. montanus (snout-vent lengths 78 mm and 75 mm), 2 R. sylvatica (snout-vent lengths 56 mm and 53 mm) and 3 Hemidactylium scutatum (snout-vent lengths 34 mm, 30 mm, and 31 mm) were obtained. Both P. montanus were beneath rocks at the same spring where the species was discovered on the previous visit. One specimen of R. sylvatica was found beneath a rotting log; the other was taken from among Sphagnum and leaf litter along the swamp’s margin. All 3 H. scutatum were taken from beneath Sphagnum and leaf litter. Other species of amphibians encountered at the swamp were Ambystoma maculatum, A. tex- anum, Eurycea bislineata, Plethodon dorsalis, P. glutinosus, Acris crepitans, and Pseudacris triseriata. The collections of H. scutatum, P. mon- tanus, and R. sylvatica cited above represent new locality records and document the western- most known populations of these species in Kentucky. The nearest published localities for each, respectively, are: Edmonson County (Brandon, Trans. Ill. Acad. Sci. 58:149, 1965), approximately 145 km to the east; Todd County (Barbour, Amphibians and Reptiles of Ken- tucky, Univ. Press of Ky. Lexington, 1971), about 65 km to the southeast; and Henderson County (Barbour, loc. cit., 1971), some 65 km to the north-northeast. In light of these findings, it seems reasonable to expect these amphibian species in suitable habitats throughout Kentucky as far west as the western edge of the Shawnee Hills Section of the Interior Low Plateaus Province. The authors wish to thank Mike Wood and Nathan Rutherford for their aid in the field and Lisa Stokes for proofing the manuscript.

Range Extensions and Drainage Records for Four Kentucky Fishes—The Kentucky distribution of Ammocrypta pellucida includes portions of the Green, Salt, Kentucky, Licking, Littke Sandy, Big Sandy, and Ohio rivers (Burr, Brimleyana 3:53-84, 1980; Rice et al., Trans. Ky. Acad. Sci. 44:125-129, 1983; Williams, Bull. Ala. Mus. Nat. Hist. 1, 1975), but this fish was last collected from the Salt River drainage in 1890 by Woolman (Bull, U.S. Fish. Comm. 10:249-288, 1892), who considered the species to be common. Two specimens col- lected on 1 August 1983 from the Rolling Fork at Gaddy’s Ford, 1.7 km S of Howardstown, Nelson County, confirm the persistence of A. pellucida in the Salt River drainage. Although historically A. pellucida had a wide distribution in Kentucky and may at times be collected in good numbers at certain localities (Rice et al., loc. cit.; per. obs.), the species is considered threatened in Kentucky (Branson et al., Trans. Ky. Acad. Sci. 42:77-89, 1981) and is being evaluated for possible addition to the U.S. endangered and threatened species list (U.S. Fish and Wildl. Serv., Fed. Reg. 47:58454-58460, 1982). Although Clay (The Fishes of Kentucky, Ky. Dept. Fish. Wildl. Resour., Frankfort, 1975) referred to 2 collections (KFW 1352 and 1746) of Etheostoma maculatum from the upper Ken- tucky River, the specimens were not found by the authors in the University of Louisville and Kentucky Department of Fish and Wildlife Resources collections. Etnier (in Lee et al., Atlas of North American Freshwater Fishes, 1980) and Burr (loc. cit.) noted E. maculatum from the Green and Cumberland rivers only in Ken- tucky. William L. Fisher, University of Louisville, brought to the junior author’s atten- tion one juvenile Etheostoma (Nothonotus), subsequently identified as Etheostoma maculatum, from the North Fork of the Ken- tucky River at the mouth of Rock Lick Creek, Breathitt County, 14 March 1981. This collec- tion represents the first confirmed record of E. maculatum from the Kentucky River and lends credence to Clay’s (loc. cit.) records for the Middle Fork. It is recommended that adult specimens be sought to help define the species taxonomic affinities and range in the Kentucky River. Notropis emiliae was previously known in Kentucky from Ohio River tributaries upstream Trans. Kentucky Academy of Science — 45(3-4) to and including the Green River drainage (Clay, loc. cit.; Burr, loc. cit.). Two specimens, col- lected on 1 November 1983 from Pottinger Creek, Nelson County, 1.3 stream km upstream from the Rolling Fork confluence, extend the range of N. emiliae in the Ohio River valley of Kentucky upstream to include the Salt River drainage. Trautman (The Fishes of Ohio, Ohio State University Press, Columbus, 1981) assumed N. emiliae was extirpated from Ohio River tributaries in Ohio. The Salt River record represents the farthest upstream extant popula- tion in the Ohio River drainage (Gilbert and Bailey, Occas. Pap. Mus. Zool. Univ. Mich. 664, 1972). Notropis venustus is known in Kentucky from 2 localities each in Bayou du Chien, the Mississippi River, and the lower Ohio River (Burr, loc. cit.) and one locality in Mayfield Creek (Rice et al., loc. cit.). A single specimen of Notropis venustus, secured 19 May 1982 from Obion Creek 3.4 km SSW of Milburn and 0.15 km §S of the Carlisle-Hickman County line in Hickman County, is the first record of the species from that stream. The specimen was collected with Notropis lutrensis and Notropis lutrensis x N. venustus hybrids. Smith and Sisk (Trans. Ky. Acad. Sci. 30:60-68, 1969) reported Notropis lutrensis in their survey of the system. Notropis venustus is regarded as of special con- cern in Kentucky (Branson et al., loc. cit.). The species reported herein appear to have extremely localized distributions in the Ken- tucky drainages covered. Ammocrypta pellucida and N. emiliae each occurred in one of 18 collections made in the Salt River drainage during this survey and were not collected from the drainage during other recent fish surveys (Henley, Ky. Dept. Fish. Wildl. Resour. Bull. 67, 1983; Hovt et al., Trans. Ky. Acad. Sci. 40:1-20, 1979; W. L. Fisher, pers. comm.) The absence of E. maculatum in previous surveys of Kentucky River drainages (Jones, Ky. Dept. Fish. Wildl. Resour. Bull. 56, 1973; Branson and Batch, Southeast. Fishes Council Proc. 4(2):1-15, 1983; and others) suggests an extremely localized distribution. The darter subgenus Nothonotus often occurs in habitats which are difficult to sample and members of this subgenus have recently been discovered in rivers in Kentucky and elsewhere after having been missed by previous surveyors (Warren and Cicerello, Brimleyana in press; Williams and Etnier, Proc. Biol. Soc. Wash. 91(2):463-471, 1978). The distribution of Notropis venustus within Ken- tucky drainages may also be characterized as localized. This pattern is observed even in drainages where suitable habitat is relatively abundant (Burr, loc.cit.). Notes 159 Richard R. Hannan, Director of the Ken- tucky Nature Preserves Commission (KNPC), supported this work and the KNPC staff lent field assistance; Mr. William L. Fisher, Universi- ty of Louisville, provided the E. maculatum specimen; and Dr. B. M. Burr, Southern Illinois University at Carbondale, confirmed the N. venustus identification and provided distribu- tional information—RONALD R.

REDISCOVERY OF THE RARE KENTUCKY ENDEMIC SOLIDAGO SHORTII T. & G. IN FLEMING AND NICHOLAS COUNTIES.—Solidago shortii a member of the angiosperm plant family Com- positae (= Asteracaea), is one of the two goldenrods endemic to Kentucky. (The other one is S. albopilosa E. L. Braun.) Historically, S. shortii was known only from 4 counties in Kentucky: Fleming, Jefferson, Nicholas and Robertson (Braun, E. L. 1941. Rhodora 43: 484; Medley, M. 1980. Status report on Solidago shortii submitted to the U.S. Fish and Wildlife Service, Unpubl.). This species currently is under status review by the U.S. Fish and Wildlife Service for listing as federally endangered (Federal Register 45 (242): 82538. 15 December 1980). In a status report on S. shortii to the Fish and Wildlife Service, Medley (1980) concluded that the only known extant population of this species in is “.. . Blue Lick State Park along both sides of the Old Buffalo Trace Trail and in edges of a nearby cedar glade.” Thus, the pur- pose of this short note is to report the rediscovery of S. shortii in Nicholas and Flem- ing counties. The localities follow: NICHOLAS CO.: Along east side of U.S. 68, 0.16 km south of the Robertson County line, J. & C. Baskin #2094 (KY), 11 September 1983; Along east side of U.S. 68, 0.48 km south of Licking River, J. & C. Baskin #2095 (KY), 11 September 1983. FLEMING CO.: 2.4 km NE of Blue Licks Bat- tlefield State Park on U.S. 68 and 0.8 km E on old U.S. 68, across road from the Assembly of God Church, J. & C. Baskin #2096 (KY), 11 September 1983. In addition, we found a second site for the species in Blue Licks Battlefield State Park: ROBERTSON CoO.:: Blue Licks Battlefield State Park, W of and adjacent to the camping area, J. & C. Baskin #2093 (KY), 11 September 1983. Medley (1980) reported that the largest popula- tion of S. shortii in Blue Licks Battlefield State Park recently was destroyed during construction of the camping area. Apparently, the plants still growing adjacent to the camping area are part of a larger population that existed in this part of the park prior to construction of the camping area. Although the 4 additional extant popula- tions of S. shortii reported here extends the known number of individuals in the species population by perhaps a few hundred, we agree with Medley (1980) that the species should be listed as endangered at the federal level. Specimens of S. shortii cited in this note have been annotated as such by Max Medley.—JERRY M. BASKIN and CAROL C. BASKIN, School of Biological Sciences, University of Kentucky, Lexington, KY 40506-0225. Notes on Kentucky Mammals: Myotis keenii and Sorex longirostris— Myotis keenii, a northern species, is one of the scarcest bats in Kentucky (Barbour and Davis, Mammals of Kentucky, Univ. Press of Kentucky, Lex- ington, 1974). Most specimens have been taken by netting at caves in summer. All summer specimens previously taken in Kentucky have been males. On 30 June 1983, Chadwick, in a study to assess potential environmental impact of the proposed Means Oil Shale Project near Jeffer- sonville, netted a lactating female Myotis keenii over West Fork Creek, Menifee Co., Ky. The nearest locality where this species is known to bear young is Roosevelt Lake, Scioto County, Ohio (Brandon, J. Mammal. 42:400-401, 1961). In Missouri, Caire et al., (Amer. Mid Nat 102:404-407, 1979) netted lactating M. keenii in June. Also of interest is a southeastern shrew, Sorex longirostris taken in Foley Hollow, Montgomery Co., Ky. on 15 August 1983. This locality extends the known range of the species into eastern Kentucky 100 km from the Franklin- Scott County line (Caldwell and Bryan, Brimleyana 8:91-100, 1982). Specimens collected during this project have been desposited in the University of Kentucky collection: JAMES W. CHADWICK, Chadwick and Associates, 5767 South Rapp St., Littleton Co., 80120 and WAYNE H. DAVIS, School of Biological Sciences, University of Kentucky, Lexington 40506. NEWS AND COMMENTS PRESIDENT’S REPORT TO THE KENTUCKY ACADEMY OF SCIENCE As the Kentucky Academy of Science celebrates its 70th Anniversary, the objectives of the organization are as relevant as when first written. To refresh your memory, I share with you those objectives as they appear in the KAS Constitution: 1) to encourage scientific research, 2) to promote the diffusion of scientific knowledge, and 3) to unify the scientific interests of the Commonwealth of Kentucky. Much is being said about the scientific com- petency, or rather the lack thereof, of the present generation of students both in the Commonwealth and throughout the Nation. It’s true that much is being said and written but very little is being done. There is tremendous oppor- tunity for the Academy to significantly impact science and mathematics education for Ken- tuckians. We must do more than merely offer our services, our combined and individual exper- tise, and our willingness to provide resources. We must become actively involved in the decision-making process. It is a most opportune time for the scientists of Kentucky to work con- certedly in the design and development of an eclucational construct that is both relevant and futuristic. I ask that you join me in reflecting on best possible solutions to our educational prob- lems and that you than share your ideas with other members of the Academy, the Executive Committee, and me. In turn, we can then in- teract with other scientific societies in a combined effort to impact state programs. This year’s emphasis on education is a natural progression of the Academy’s recent history. Significant gains were made under the presidencies of Dr. Philley, Dr. George, and Dr. Rodriguez in strengthening ties between academe and industry. In 1982 meeting in Ashland was most impressive to those of us in academe. The 1984 annual meeting is scheduled for November 9, 10 in Frankfort and the focus will be the interrelationships of academe/in- dustry/government. Such a theme and place seem appropriate for the times. I consider it a signal honor to serve as Presi- dent and am looking forward to working with you in carrying out the objectives of the Academy. Your comments and suggestions will be appreciated. Sincerely, Gary W. Boggess IMPORTANT PUBLICATIONS BY KENTUCKY SCIENTISTS The long-awaited book, The American Darters (University Press of Kentucky), by Drs. Robert A. Kuehne and Roger W. Barbour has appeared. It is a stunning piece of work, full of information of value to field biologists, novice fish-watchers, museum taxonomists, natural history photographers, and biogeographers. The full-color photographs are of excellent quality. Although there is another book present- ly in print on the American percid fishes called darters, no book on any segment of the North American fish fauna has ever presented so many species in color photography. The book will cer- tainly find a lasting place in the library of anybody with even a remote interest in fishes. “Distribution and Status of Ohio River Fishes” by William D. Pearson and Louis A.

RH - Geochemical Analysis in Kentucky — Perkinson et al. TRANSACTIONS of the KENTUCKY ACADEMY of SCIENCE March 1985 Volume 46 Numbers 1-2 Geochemical Analysis of the Providence Limestone Member of the Sturgis Formation (Upper Pennsylvanian) MARY C. PERKINSON and GARY L. KUHNHENN, Department of Geology, Eastern Kentucky University, Richmond, KY 40475 ALAN D. SMITH, Coal Mining Administration, College of Business, Eastern Kentucky University, Richmond, KY 40475 ABSTRACT The Providence Limestone Member, Sturgis Formation (Upper Pennsylvanian), cropping out in the western Kentucky coal field, represents 2 transgressive carbonate units deposited in separate and distinct environments. The lower and upper limestone units occur between the Kentucky No. 11 and No. 13 coal beds and are separated by claystone and the Kentucky No. 12 coal bed, or a smut zone where the No. 12 coal is absent. Both limestone units were deposited over broad, relatively flat-lying platforms built upon a deltaic system. A geochemical analysis of the Providence Limestone Member was conducted to obtain cation information to aid in an understanding of the depositional history of the area. The analysis was determined by atomic ab- sorption spectrophotometry and involved only the carbonate portion of the rock. The results, while adding helpful information about environments of deposition, must be viewed with caution in that the insoluble (noncar- bonate) portion of the rock, as well as diagenetic factors, may affect the distribution and amount of elements. The elements analyzed were calcium, magnesium, iron, manganese, strontium, sodium, and potassium. In reviewing the results, certain variations occur within the limestone units. Both the lower and upper limestone units consist of low-magnesium calcite, which may be considered to be indicative of an environment with normal marine salinity. Slight variations do occur between cores and probably reflect localized conditions within the units. INTRODUCTION Glenn (1) assigned the name Lisman For- mation to a stratigraphic sequence of upper vidence, Kentucky. Glenn described the Pro- vidence as consisting of an argillaceous, impure, Pennsylvanian rocks overlying the Carbondale Formation. Lee (2) assigned the term Henshaw Formation to a sequence of rocks overlying the Lisman Formation. Further studies indicated minor variations in the lithology of these units; hence, the names were abandoned and the 2 units were combined and reassigned to the Sturgis Formation (3). The Providence Limestone was first describ- ed by Hutchinson (4), who referred it to the lower limestone unit as the Jelly Limestone. Glenn (1) assigned the name _ Providence Limestone to a unit of limestone found above the Kentucky No. 11 coal in the vicinity of Pro- irregularly bedded limestone, locally containing shale partings. Glenn found the Providence to be a valuable horizon maker and was able to cor- relate it with the Brereton Limestone of Illinois. Glenn further defined the Providence as occurr- ing between the Kentucky No. 11 and Kentucky No. 12 coal beds. After extensive mapping it has been shown that Kentucky No. 12 coal beds, referred to by Glenn, is actually the Kentucky No. 13 coal. The Providence Limestone Member of western Kentucky is a Middle-Upper Penn- sylvanian (Desmoinesian) marine unit located at the base of the Sturgis Formation. The Pro- vidence Limestone lies along the southeastern rim of the Eastern Interior Basin and is regional- ly persistent throughout the western Kentucky coal fields. The Providence Limestone Member is located between the Kentucky No. 11 and No. 13 coal beds and has been noted to occur as 2 distinct beds referred to as the upper and lower units (3). These 2 beds are separated by the Ken- tucky No. 12 coal bed, or by a dark clayey shale where the No. 12 coal is absent. TECTONIC SETTING Pennsylvanian coal-bearing rocks of the western Kentucky coal fields are exposed in an area of about 11655 km? (5). The rocks are, in general, deltaic and tidal flat in origin and ex- tend out over a gentle slope. They consist mainly of shale, siltstone, sandstone, and minor amounts of coal and limestone. The study area, located in the western Ken- tucky coal fields, is within the Eastern Interior Basin (Illinois Basin). Although the major por- tion of this basin is concentrated around the state of Illinois, it does encompass rocks in Ken- tucky, Indiana, Iowa, and Missouri. The basin is a spoon-shaped depression with its major axis trending in a _ north-northwest to south- southwest direction with the southern tip of the spoon in Kentucky (6). It is bordered on the west by the Ozark uplift and on the east by the Cin- cinnati Arch. In Kentucky, the basin is dominated by 3 structural features: (1) the Rough Creek fault system, (2) the Moorman Syncline, and (3) the Pennyrile fault system (Fig.1).

STRATIGRAPHY The Pennsylvanian rocks of the western Kentucky coal fields are considered to be an extension of the Eastern Interior Basin and rest unconformably on the Upper Mississippian Chesterian sequence. The Pennsylvanian sequence in western Kentucky is about 1070 m thick (7) and, in ascending order, consists of the following formations: (1) the Caseyville, (2) the Tradewater, (3) the Carbondale, and (4) the Sturgis (Fig. 2). As mentioned previously, the Sturgis Formation contains those rocks former- ly belonging to the Lisman and Henshaw forma- tions. Pennsylvanian strata are unroofed in most areas of the Eastern Interior Basin. For this Geochemical Analysis in Kentucky — Perkinson et al. reason the upper limit of the Sturgis Formation was undefined. Douglas (8) has since identified Triticites sp. from a drill core located in Union County, Kentucky, indicating the presence of Permian-age material within the southern part of the Eastern Interior Basin. In this area, the Sturgis Formation is estimated to be 610 m thick (5). With the discovery of Permian-age material in this area, the term Mauzy Formation has been tentatively proposed for these rocks (9). The Mauzy Formation is an estimated 120 m in thickness and is very similar, in terms of lithology, to the underlying Pennsylvanian strata, with the exception of a higher percentage of limestone. Permian rocks in the Eastern In- terior Basin have been found only in a small down-faulted area in Union County, Kentucky. STURGIS FORMATION The Sturgis Formation, which overlies the Carbondale Formation, contains all Upper Pennsylvanian strata in the western Kentucky coal field. The lower contact for the Sturgis For- mation is placed at the base of the Providence Limestone Member (3). In most of this area, the upper portion of the Pennsylvanian has been removed by erosion, hence, no upper contact has been determined. Permian rocks have, however, been identified from core material in Union County, Kentucky, as_ previously mentioned. The Sturgis Formation, containing rocks that were previously assigned to the Lisman and Henshaw formations, consists of sandstone, siltstone, shale, limestone, and coal. Since a large portion of the Sturgis is concealed by loess, alluvium, and collevium, no adequate outcrop for a type section has been designated. Data from two core holes drilled by Cities Ser- vice Oil Company, both northeast of Sturgis, Kentucky, have been combined and identified as the type area and composite section for the Sturgis Formation (3). In ascending order, the members of this formation are: (1) the Prov- idence Limestone, (2) the Kentucky No. 12 (Paradise) coal, (3) the Kentucky No. 13 (Baker) coal, (4) the Anvil Rock Sandstone, (5) the Ken- tucky No. 14 (Coiltown) coal, (6) the Madison- ville Limestone, (7) the Carthage Limestone, (8) the Lisman coal, and (9) the Geiger Lake coal. Sandstone makes up 30 to 50 % of this for- mation and is the dominant rock type (3). It is commonly light gray, weathering to yellowish- brown, and is fine-to-medium grained except in channel deposits where it is locally con- glomeratic. Siltstone, light to dark gray, is usually interbedded with sandstone and shale. The shale is generally medium to light gray and silty, but when associated with coal beds it is dark gray to black and carbonaceous. It also com- monly occurs as olive green and clayey, with slickensides. Kehn (3) notes that the shale contains brachiopods and crinoids only when interbedded with limestone. In general, the coals of the Sturgis Forma- tion are not as thick or widespread as those of the underlying Carbondale Formation. The lower section does, however, contain the Ken- tucky numbers 12, 13 and 14 coals which locally are very thick and of economic importance. The Kentucky No. 14 coal has been reported to be more than 4 m thick in some drill holes (3). Limestone beds of the Sturgis Formation are thicker and more abundant than those of the underlying Pennsylvanian formations, but make up only 5% of the Sturgis (3). They are generally light to dark gray, fine-grained, fairly dense, and usually occur in beds 0.01 to 0.3 m in thickness. PROVIDENCE LIMESTONE MEMBER The Providence Limestone Member consists of all limestone beds located between the Ken- tucky No. 11 and No. 13 coal beds. Exposures utilized in this study consist of 2 limestone beds, referred to as the upper and lower units (Fig. 3). At some localities as many as 4 different beds, separated by clayey shale and, locally, thin lenses of sandstone, have been described (3). In the area around Sturgis and Providence, Ken- tucky, the Providence limestone comprises as much as 10 m of strata (3) extending from the top of the No. 11 coal bed to just beneath the No. 13 coal bed. In the study area, however, the Providence consists of only a maximum of 3.4m within the same interval. The lower unit of the Providence is general- ly light gray to dark gray, fine-grained, dense, fossiliferous and averages about 0.6 m in thickness within the study area. Dark zones of argillaceous material are common within the lower unit and tend to contain a greater abun- dance of fossil material as well as a crystalline texture. The fossil assemblages commonly in- clude brachiopods, pelecyopods, pelmatozoans, bryozoans, foraminifera, and algae. The upper unit is separated from the lower unit by 2 to 3 m of claystone and shale partings, as well as the Kentucky No. 12 coal bed, or a dark clayey shale where the coal is absent. The Kentucky No. 12 horizon occurs about 0.61 m beneath the upper unit. The upper unit is generally a buff to light brown, very dense, microcrystalline limestone containing calcite blebs and abundant sub-rounded limestone clasts. Weathered portions tend to be extensive- 4 Trans.

In some _ localities Stigmaria is present along the base of the upper unit where it is interbedded with claystone and shale. Other than the Stigmaria, ostracods were the only fossils found in the upper limestone. The Kentucky No. 13 coal bed generally oc- curs 0.3-0.6 m above the top of the upper unit within the study area. It averages about 1.0m in thickness and tends to contain high amounts of sulfur. In most of the study area, the Pennsylvan- ian section above the Kentucky No. 13 coal has been removed by erosion. The Madisonville Limestone Member occurs about 61 m above the base of the Sturgis Formation (3) and is light to medium gray, fine to medium crystalline, and fossiliferous. It may contain as many as 4 separate limestone beds, and is_ usually associated with sandstone, claystone, shale, and coal. METHODS The study area is located within the Western Kentucky Coal Field, in Ohio and Muhlenberg counties, and is represented by five 7.5 minute geologic quadrangles (Fig. 4). Nine stratigraphic sequences, including outcrops and cores, were located and sampled at 0.3 m inter- vals or where a lithologic change occurred. Ad- ditional cores were located and studied to pro- vide a better understanding of the unit. A geochemical analysis of the Providence Limestone Member was conducted to obtain ad- ditional information to aid in an understanding of the depositional history of the area. The analysis was determined by atomic absorption spectrophotometry and involved only the car- bonate portion of the rock. The core samples were pulverized, then placed in solution by dissolving in hydrochloric acid and distilled water. The results, while adding helpful infor- mation about environments of deposition, must be viewed with caution in that the insoluble (noncarbonate) portion of the rock, as well as diagenetic factors, may affect the distribution and amount of elements. The elements analyzed were calcium, magnesium, iron, manganese, strontium, sodium, and potassium. Many factors govern the distribution of elements in limestones including: (1) the abun- dance and diversity of the source biomass, (2) environmental effects at the time of deposition, (3) the influence and composition of detrital material, (4) tectonic activity, and (5) diagenetic processes. The presence of these variables will greatly influence the final outcome of the elemental distribution within the limestone. Diagenetic processes alone may play a large role in altering the composition of the original sediment. Hence, it may be impossible to com- pletely interpret the environment at the time of deposition through geochemical studies alone. RESULTS The elemental data are summarized in Tables 1 through 3. Table 1 lists the elemental content of each individual sample analyzed, while Table 2 shows the average elemental con- tent of each core. Slight variations do occur between the cores and probably reflect localized conditions within the units. Significant as well as insignificant variations occur between the lower and upper limestone units (Table 3).

Kentucky Academy of Science — 46(1-2) diagenesis. In sea water, the average concentra- tion of Na+ is 1050 ppm as compared with 25 ppm for fresh groundwater (10). Where the 2 are mixed, the concentration of sodium will be directly proportional to the degree of mixing. Land and Hoops (10) noted that due to the lack of information on the Na+ /Ca and Na/Mg partitioning coefficient in natural carbonates, no acceptable method for determining paleosali- nites at the time of deposition has been found. They do suggest, however, that the salinity of the latest diagenetic solution may be indicated by the bulk sodium content. The analysis of strontium in carbonate rocks has been the subject of numerous studies. Many of these studies have attempted to show the relation of the concentration of strontium with environmental parameters like salinity, temperature, and organisms. In determining the strontium concentration of precipitated car- bonate minerals, the Sr * ?/Ca* ? ratio has been noted to play an important role (11). Kinsman (11) noted the ability of organisms to incor- porate strontium into their shell structures and found that individual organisms may contain up to 20,000 ppm Sr*? when composed mainly of argonite. This association of higher amounts of strontium with argonitic shells than with calcitic shells has also been suggested in other studies by Kulp et al. (12) and Pilkey and Goodell (12). The Sr/Ca ratio, as noted by Lowenstam (14), is thought to be related to the proportions of aragonite and calcite found in tests of organisms where the presence of the organisms are depen- dent on water temperature. From this he con- cludes that warmer waters contain higher amounts of strontium. After studying numerous carbonate rocks and associated fossils, Kulp et al. (12) suggest that temperature is not an im- portant factor, but that the presence of organisms is more important. They note the organisms themselves, regardless of shell com- position, account for a higher concentration of strontium as compared with that of the surroun- ding matrix. The presence of iron in carbonate rocks is believed to have resulted from the influx of detrital material into the environment of deposi- tion (15). This material may have been intro- duced into the environment by the influx of fresh water as well as from diagenetic alterations of compounds to form siderite (15). The Ca/Mg ratio in carbonate rocks will decrease as the salinity increases (16). Ingerson (16) noted that widespread marine fossil assemblages occur only in areas where the Ca/Mg ration is greater than 50. The absence of fossils is generally indicative of an environment with increased salinity, hence, a low Ca/Mg ratio. In reviewing the results, certain variations occur within the limestone units. Both the lower and upper limestone units consist of a low- magnesium calcite. Folk and Land (17) consider this association to be indicative of an environ- ment with a normal marine salinity. The iron content of the upper limestone unit is significant- ly higher than that of the lower limestone unit. This reflects the presence of the iron-oxide stain abundant in the upper limestone unit. This stain is present in both core and outcrop locations, hence, it is not a result of recent weathering. Berner (15) noted that the majority of iron present in carbonate rocks has been derived from the detrital materials. The pyrite found in the lower limestone unit is believed to have been introduced into the environment as hematite, and later reduced to pyrite and siderite. There is a slight variation in the content of manganese between the lower and upper limestone units. Khawlie and Carozzi (18), in their study of the Brereton Limestone, associated the presence of manganese with iron minerals and the influx of fresh water. The oc- currence of manganese, along with iron, may be associated with the slight increase of manganese in the upper unit. Ronov and Ermishkina (19) noted that the presence of manganese in amounts greater than 0.01% is indicative of a humid environment. This may be due to the tendency of manganese to become concentrated in organic acid-rich waters found in a humid environment. All samples analyzed show a manganese concen- tration significantly over that of 0.01%. This relationship reflects the humid climate present at the time of the formation of the Pennsylvan- ian coal swamps. There is a small variation in the strontium concentration between the lower and upper limestone units, with slightly more present in the lower limestone unit. The higher concentra- tion in the lower unit reflects the abundant fossil assemblages that occur in the lower unit while the upper unit is very sparse in fossil content. Variations in both sodium and potassium that occur within the lower and upper units are insignificant. Although sodium plays an impor- tant role in the percentage of salinity (20), there are no adequate methods to determine paleosalinities at this time. 10. 11.

SMITH Coal Mining Administration, College of Business Eastern Kentucky University, Richmond, KY 40475 ABSTRACT Engineering properties of 6 representative sites of silty-clay mixtures in and around Richmond, Kentucky were investigated to help understand and qualify functional relationships among common soil strength and con- sistency measures in this area. Since all the sites are scheduled for future development in terms of a variety of construction projects, and the silty-clay mixtures, classified by the uniform classification system as SC, are common throughout Madison County, extensive laboratory tests were performed. On all sample sites, standard and modified energies of compaction, via the Proctor Compaction Density Laboratory Test, were completed a total of 3 times. In addition each layer, 3 in the standard and 5 in the modified, in the compaction mold was sampled a total of 3 trials for water content, vane shear, and compressive strength, as measured by the penetra- tion test. Atterberg Limits were performed on 3 representative samples to determine the variability of the plastic range. Multiple linear regression techniques were applied in the hypothesis testing process, which resulied in 13 hypotheses being statistically significant. In general, higher energies of compaction were associated with lower water content, less void space, higher shear and compressive strengths, lower water contents were found to be related to higher maximum dry densities, higher compressive strengths with greater maximum dry densities, and vane shear strengths positively related to compressive strengths as measured by the penetration test. INTRODUCTION Problems associated with soil mechanics and foundation engineering are usually solved through a combination of theoretical knowledge, awareness of the precedents in the area, geology, history, and properties of the soil conditions obtained from laboratory and field testing procedures. Only through a combination of these features and an appreciation of the func- tion of the proposed structure can a proper design and construction program be formulated. Characterization of the soil properties and subsequent engineering judgments are based on laboratory tests performed on representative samples taken during a site investigation. The scope, type, and quality of the corresponding site investigation are important and decided upon only after considering the subsequent laboratory test program (1, 2, 3, 4). The engineering classifications in common use are based on the size composition of the solid constituents and on their interaction with the water substance as evidenced by the resul- tant volume and consistency changes (5, 6). Hence, relationships between water content, op- timal strength, and the soil’s volume and con- sistency behavior should be established before the design and construction of structures are under way. Although each site warrants its own preliminary exploration and investigation of physical parameters, general guidelines con- cerning strength properties and these parameters for similar soils and environmental conditions would provide valuable aids in engineering design and result in cost savings by not performing repetitive tests. The principal goals of this research are to help establish ranges of basic soil mechanics and foundation data of representative soil types in the Madison County area, Kentucky, for con- struction and scientific purposes. In addition, the interrelationships among fundamental laboratory tests of strength and soil consistency for representative soil types need to be estab- lished. METHODS Laboratory tests, including water contents, Atterburg Limits determination, Proctor density tests with both standard and modified compac- tion energies, vane shear and penetration tests were performed on representative samples of dominant residual soil complexes of silt-clay. All the samples used in the study were collected from potential building sites on exposed cultivated land in and near Richmond city limits and were classified as SC, using the unified soil classification system (7). Properties of Silty Clay in Kentucky — Smith 9 Atterburg Limits The soil consistency tests, originally established by Atterberg (8), have been further developed and standarized by practicing engineers and scientists. The Atterberg Limits used in the present study included the liquid limit and plastic limit. The liquid limit (LL,Wy) is essentially the water content at which 2 halves of a soil cake prepared in a standarized manner in the cup of a liquid limit device will flow together from a distance of 0.5 inch (1.25 cm) along the bottom of a groove when the cup is dropped 25 times for a distance of 1 cm at the rate of 2 drops per second (ASTM D423). Fang (9) provided a simple procedure for the deter- mination of the liquid limit of soils, which is derived from the flow index: Ir = LL-W, logN - log25 LL = W,, + IglogN 25 Where If is the flow index approximately equal to the slope of the flow curve; N is the number of blows (17 AS j = nN ~~ 2 é es Fig. 5.

Kentucky Academy of Science — 46(1-2) 25 GEOLOGY The Shawnee Hills section of the Interior Low Plateaus is the physiographic regional set- ting for the arches (5). The topography of the local area is characterized by rugged to rolling hills and steep-walled valleys. Elevations range from 90 to 250 m. This area is known for its ex- tensive faulting and abundant fluorite deposits. Over 75 per cent of the fluorite production in the United States has been from the surrounding Kentucky-Illinois mining district. Significant lead and zinc deposits associated with the fluorite are currently being investigated by private industry. Fig. 7. View of the window above Alcove Arch According to Heyl and Brock (6), “the district is located in the most complexly faulted area in the craton of the United States.” Three major fault zones, the Shawneetown-Cottage Grove, the Rough Creek, and the New Madrid, intersect approximately 24. 5 km north of the ar- ches. Some north-trending faults are present as are a small number of east-trending faults; however, the predominant orientation of faults on the Golconda Quadrangle is northeast. Mantle Rock and Alcove Arch lie within a graben that is approximately 0.9 km wide and ms 5.3 km long (Fig. 8). Figure 8 is a generalized map niodified from Amos (4). Displacement within the graben is estimated to be 46 m. The graben is bounded on the southeast by a fault which trends N39°E. This fault is associated with the Rosiclare Fault System which is located .4 km east of the arches. The graben is also bordered on the northwest by a fault of the Big Creek Fault System which trends N18°E and is situated .8 km west of the arches. The stresses responsible for this post-Pennsylvanian faulting were also of primary importance in the formation of the extensive joint sets of the study area. The larger arch, Mantle Rock, is oriented N45°E. As previously stated, the major joint in the backwall of this arch strikes N45°E and a secondary joint trends N78°E. The joints in Alcove Arch have bearings of N44°E and N68°E. Joint orientations exemplify conjugate shears that developed approximately 30° east and west of the principal stress orientation in the region.

General geology of the study area [Modified after Amos (4)]. 26 Natural Arches in Kentucky — Kind and Shelby STRATIGRAPHY The arches have formed in the Pounds Sandstone Member of the Pennsylvanian Caseyville Formation immediately above a regional Mississippian /Pennsylvanian unconfor- mity (Fig. 8). The Pounds Sandstone in the study area varies from 25-40 m thick. The sand- stone is medium to coarse-grained with 1.5 cm quartz pebbles. It is generally light gray in color and shows some cross beds that dip to the south and southwest. Honeycomb weathering is very well defined on the northeastern exposures of the outcrops (Fig. 9). some Liesegang layering, the deposition of limonite and hematite in joints and roughly concentric rings, is present at Man- tle Rock, but absent at Alcove Arch (7). A local unconformity exists below the Pounds. Beneath the unconformity an unnamed shale, siltstone, and sandstone member of the Caseyville is present. This member is represented at the site by a thin, even-bedded, light gray siltstone which is approximately 9 m thick. In some near- by locations this member is completely cut out by the overlying members (4). The unnamed siltstone is exposed in the stream bed 15 m east of the larger arch and about 0.4 km southwest along another small stream. Fig. 9. Honeycomb weathering in the Pounds Sandstone Member of the Caseyville Formation. MODE OF FORMATION Mantle Rock was formed as a result of physical and chemical weathering activity along the sandstone cliff face and associated joints. It is also possible that an intermittent stream which flows toward the southwestern corner of the span assisted in the removal of material along a small portion of the cliff face. The weathering processes alone or in combination with stream erosion removed material at the base of the cliff to a point where a widened frac- ture parelleling the face of the cliff was en- countered as shown in the cross-sections in Figure 10, Steps 1 through 3. As weathering pro- gressed, another widened fracture was en- countered (Step 4). Chemical weathering weakened the bedrock along the joints resulting in the removal of support and gradual collapse of roof material (Step 5). Subsequent weather- ing and mass wasting has removed more material resulting in the present situation, Step Trans. Kentucky Academy of Science — 46(1-2) 27 6. Infiltration of water into the cross strata and Liesegang layering has helped to accelerate the weathering processes. The smaller arch has formed in essentially the same manner as Mantle Rock except for the lack of any stream erosion due to the elevated entrance of Alcove Arch and a lack of Liesegang layering. The life of this arch may be short geologically due to the presence of a vertical fracture that cuts the northeastern end of the span. As weathering processes continue along this fracture the span will weaken and finally collapse, leaving only a rock shelter. Fig. 10. Mode of arch formation. SUMMARY AND CONCLUSIONS Mantle Rock and Alcove Arch are situated farther west in Kentucky than any like structures that have been documented. Both arches have formed in response to chemical solution and physical weathering along widened intersecting joints which are directly related to regional structural trends. Undercutting by stream ero- sion may have been a factor which influenced the collapse of roof material from the southwest end of Mantle Rock but had no influence on the formation of Alcove Arch. Infiltration along pro- minent crossbeds and Liesegang layering helped to accelerate the weathering processes at Man- tle Rock and may be responsible for a more mature stage of arch development. Although crossbeds which facilitate weathering processes are present at Alcove Arch, visible Liesegang layering is absent. Numerous other undocumented natural ar- ches and/or bridges may exist along the exten- sive outcrop of the Pounds Sandstone Member due to the existence of the aforementioned con- ditions. It should be noted that the scenic area surrounding Mantle Rock and Alcove Arch is perfectly suited for field instruction and exten- sive geologic investigations on such topics as fracture analyses, differential weathering pro- cesses, and sedimentary structures.

RH - Paddlefish Reproduction in Kentucky — Bronte and Johnson GROWTH OF PADDLEFISH IN TWO MAINSTREAM RESERVOIRS WITH REFERENCE TO COMMERCIAL HARVEST' Charles R. Bronte? and Donald W. Johnson * Hancock Biological Station, Murray State University, Murray, Kentucky 42071 ABSTRACT Adult and juvenile paddlefish from commercial net catches from Kentucky Lake and Lake Barkley were studied to determine growth and maturation information. Backcalculated lengths at dentary bone annuli re- vealed rapid growth for the first 4 years with body length of 10 cm or greater attained within the first year. Dif- ferential growth in terms of weight at age between the sexes was noted. Males appeared to become sexually mature in their sixth or seventh year. Lengths and weights of mature males sampled by the fishery ranged from 74 to 97 cm and 5.3 to 13.2 kg, respectively. Gravid females sampled ranged from 88 to 102 cm and 16.8 to 22.7 kg; all were 9 years or older. Mesh sizes currently used by commercial fishermen are selecting for mostly im- mature fish and may have possible negative affects on breeder recruitment under intensive fishing pressure. INTRODUCTION Paddlefish (Polyodon spathula) have undergone some restrictions in range and declines in numbers since 1900 from overharvesting and destruction of suitable spawning habitat (1, 2, 3, 4). Impoundments throughout the Mississippi River drainage have flooded and/or made inaccessible many spawn- ing areas. Fifty percent (124 tons) of the total recent commercial harvest (260 tons) of paddlefish comes from the Tennessee and Cumberland Rivers (5) located in southwestern Kentucky and western Tennessee. Recently, commercial fishing pressure has increased in these areas. Reduced imports of Caspian Sea sturgeon eggs have made it necessary for the caviar industry to switch to paddlfish as an alternate egg source. High prices ($65/kg) paid for paddlefish roe pro- vide incentive for increased fishing pressure. In 1979, Lake Barkley (Cumberland R.) and Kentucky Lake (Tennessee R.) in western Ken- tucky were reopened to gill and trammel net usage to harvest under-utilized buffalofish (Ictiobus spp.) and carp (Cyprinus carpio). Catch data from the first year (1979-1980) revealed that 6 tons of paddlefish were taken as by-catch. With this increase in harvest and potential for spawning stock damage, it became imperative to collect information on growth and maturation of these stocks to ensure responsible management. METHODS Paddlefish from the Kentucky and Ten- nessee portions of Lake Barkley (n=101) and Kentucky Lake (n = 89) were obtained from com- mercial net catches between December 14, 1980 and February 5, 1981. Kentucky permits com- mercial harvest in these reservoirs with 90-115 mm bar mesh gill and trammel nets from November 1 through March 31. A year-round gill and trammel net fishery exists in Tennessee where regulations stipulate that bar mesh sizes must be 76 mm or greater. Rostrum, body, and total lengths, as well as weight, sex, and condition of gonads were recorded and dentary bones collected from all fish. Body lengths (BL) were measured from the anterior margin of the eye to the base of the hypural bone. Rosen (6) suggested this as a more valid index of paddlefish growth than total length. Only 22% of variation in body lengths was explained by variation in rostrum length. Ages were estimated by examining dentary bone cross sections (7). Thin sections of dentary bone were cut with a rotary saw where the bone bends mesially. Sections were thinned by grind- ing on a wet stone and cleared in xylene or methyl salicylate to facilitate identifying annuli. Annuli were counted and_ backcalculation distances measured on the mesial lobe of the dentary bone section. Only growth bands which extended around the bone were considered true annuli. Most dentaries were read twice with * This work was supported in part by funds provided by the Commonwealth of Kentucky under Federal Commercial Fisheries Research and Development Project No. 2-368-R-1. * Present Address: Red Cliff Fisheries Department, Red Cliff Band of Lake Superior Chippewas, P.O.

Kentucky Academy of Science — 46(1-2) discrepancies settled by assigning the older age estimate. Backcalculations to estimate length at age were performed by measuring the distance from the middle of the central core to the distal por- tion of each annulus. All reported lengths are body lengths. Rosen (6) determined that central core development was completed after the first growing season, therefore, the core center pro- vides an appropriate reference point for backcalculation measurements. Fish length at annulus formation was estimated on the basis of direct proportional expansion (8). RESULTS The size range of fish sampled resulted from selectivity of the 90-152 mm bar mesh nets used by commercial fishermen and may not be in- dicative of true population age and size characteristics. Fishermen in Kentucky used 90-115 mm mesh nets which selected for buf- falofish, carp and catfish (Ictaluridae) with pad- dlefish incidental to the catch. Larger mesh nets (152 mm) were used by Tennessee fishermen targeting gravid paddlefish. Body lengths (cm) of commercially harvested paddlefish ranged from 32 to 102 and 27 to 139 for Kentucky Lake and Lake Barkley samples, respectively while weights (kg) ranged from 0.4 to 22.7 and 0.6 to 30.2, respectively (Tables 1 and 2).

Interpretation of dentary bones indicated that age classes 2-12 and 2-14 were represented in Lake Barkley and Kentucky Lake samples, respectively. Age at recruitment to the fishery appears to be at six to seven years when mean lengths approach 70 cm. Annual mortality estimated by catch curve analysis of age fre- quencies of fully recruited fish (>6 yrs) was 44% for Kentucky Lake fish and 45% for Lake Barkley fish. Growth data from backcalculated lengths were consistent with observed lengths at age in samples (Table 3). Growth was similar in both Table 3.

Paddlefish grew relatively rapidly during the first four years with annual increases generally greater than 10 cm. Differential growth in length between the sexes was not observed as in other studies (6, 9). Growth in length for all fish was described by von Bertalanffy equations (Table 4). Table 4.

Lake Barkley females were heavier than males after the fifth growing season with dif- ferences increasing with age. Kentucky Lake paddlefish failed to show sexual dimorphism by weight. Differences in weight may be due to the development of ovaries and associated fat bodies. Weight differences are further reflected in comparing mean calculated condition factors [K(BL)], for arbitrary length classes (Table 6). Condition generally increased with length for all fish. Lake Barkley females had higher condition values than males for most length classes. Previous to sexual maturity, Kentucky Lake females exhibited lower condition factors than males. Table 6. Calculated condition values [K(BL)] for Kentucky Lake and Lake Barkley paddlefish.

Mature males exhibited ex- panded and convoluted testes which assumed white mottled appearance and extended into the caudal end of the body cavity. Kentucky Lake mature males ranged from 74 to 90 cm in length and 8.0 to 12.4 kg in weight and were 7 to 10 years old; Lake Barkley mature males were 764 to 97 cm and 5.3 to 13.2 kg with ages ranging from 6 to 8 years. The presence of black or gray- black eggs indicated maturity in females. Although many large females were sampled, few contained eggs. Most had ovaries which were yellow to slightly pink in color extending throughout the body cavity. Gravid females from Kentucky Lake ranged from 93 to 102 cm and 16.8 to 22.7 kg, and were greater than 9 or 10 years old. DISCUSSION AND CONCLUSIONS Age frequencies of Kentucky Lake and Lake Barkley paddlefish samples were similar to samples reported from Mississippi River-Pool 13, Iowa (10); Missouri River below Gavins Point Dam, Nebraska (11, 12); and the Neosho River, Oklahoma (13); however, older fish (20-26 years) have been collected in the Mississippi River-Pool 19, Iowa (14); the Osage River, Missouri (9); Lake Francis Case, South Dakota (15); and a free flowing section of the Missouri River, South Dakota (6). Paddlefish exhibited large length increases for the first three to four years when compared to other populations (6, 7, 9, 11, 14, 16, 17, 18). Impinged young-of-the-year paddlefish from Cumberland Steam Plant (Lake Barkley, Ten- nessee), were over 30 cm in total length by late winter (19) and agree well with backcalculated estimates. As reported by others, gonad examination revealed that these fish mature relatively late in life. Testes indicated males may become sexual- ly mature at the sixth or seventh year. Helms (20) states that at maturity, testes enlarge to sizes greater than the associated fat tissue. Trans. Kentucky Academy of Science — 46(1-2) 31 None of these fish showed these characteristics. Testes expansion was limited to 10-20 mm in width as noted by Rosen (6). Gravid females were some of the largest and oldest individuals sampled. However, 91 percent of females of similar or greater size and age contained no mature eggs. It is not unusual to observe few or no ripe females in samples containing old fish (1, 4, 6, 15, 18, 20). This may indicate that only a small percentage of mature individuals spawn each year (14, 16). Rosen (6) suggested that maturation may not be age dependent, but that the formation of large egg masses may be limited by available energy. Appropriate stimuli may not be present in these reservoirs to induce egg maturation. Purkett (4) noted that warming water temperatures and rising water levels are needed to induce spawning migrations. Whether other stimuli are also required for oocyte maturation early in the season is unknown. Fast growth leading to large sizes during early life can lead to adverse consequences to the population from commercial fishing. This concept was addressed early by Adams (7) and later by Larimore (2) who both recognized that knowledge of growth rates, age at maturity, and spawning habits are imperative for responsible management and protection. Data presented here for Kentucky Lake and Lake Barkley pad- dlefish suggest that many individuals are being removed before contributing to reproduction. Mean lengths and ages of commercially harvested females are below those observed for mature fish. Absence of older fish and high total mortality rates may indicate fishing has cropped these age classes. Harvests consist of younger fish as they are recruited into the fishery. Mesh sizes (152 mm) commonly used in the Tennessee fishery may be inappropriate for maintaining favorable population structure. Use of larger mesh gill nets that select for fish greater than 80 cm should be investigated. Sport fishery harvests currently exceed surveyed commercial landings through most of the paddlefish’s range and may pose a greater threat to the species’ future than the commer- cial fishery (5). Although current fishing mor- tality rates associated with commercial fisheries will yield sustained harvests, monetary incen- tives for roe may increase total harvest levels and lead to population declines. Appropriate regulation is needed to ensure that this commer- cially and aesthetically valuable resource remains renewable. ACKNOWLEDGEMENTS Data collection would not have been possi- ble without the cooperation of commercial fishermen M. Mann, T. Melton, B. French, B. Bartee, and S. Parker. The technical and profes- sional support of Dr. Thomas Forsythe (TVA) was also critical to completion of the project. This paper is based in part on a thesis submitted by the senior author in partial fulfillment for the degree of Master of Science, Murray State University, Kentucky. LITERATURE CITED 1. Stockard, C.

Mardon and Frederick M. Rothwell Department of Biological Sciences, Eastern Kentucky University, Richmond, Kentucky 40475 and The Northeastern Forest Experiment Station, U.S. Forest Service, Berea, Kentucky 40403 ABSTRACT Azospirillum lipoferum was isolated from the rhizosphere soil of Festuca arundinacea growing on a coal surface-mined site in Eastern Kentucky. As measured by the acetylene reduction assay, this isolate fixed nitrogen at a substantially higher rate in comparison with other Azospirillum cultures. These results demonstrate the potential significance of associative nitrogen-fixation in establishing and maintaining growth of herbaceous vegetation on minesoils when nitrogen is a limiting factor. INTRODUCTION Azospirillum is an asymbiotic nitrogen- fixing bacterium characteristically found in close association with the roots of many her- baceous plants, particularly the grasses (1, 3, 4, 15). The genus is composed of 2 species, A. brasilense and A. lipoferum (14). Both species have been implicated in nitrogen fixation in the rhizosphere soil of the above plants (12). Asymbiotic nitrogen-fixing micro- organisms, including Azospirillum, have occa- sionally been isolated from rhizosphere soil of grasses used in minesoil reclamation (10). However, little information is available regard- ing the significance of Azospirillum in this type of environment. This paper presents evidence that the nitrogen-fixing capacity of an A. lipoferum isolated from the rhizosphere soil of a perennial grass, Festua arundinacea, growing on a coal surface-mined site was significantly higher than selected Azospirillum species tested. MATERIALS AND METHODS Microorganisms—The primary microbial isolate in this study has been tentatively iden- tified as Azospirillum lipoferum based upon the results of morphological and physiological tests (14). Two morphologically distinct colonies of the original isolate were obtained via the streak- plate method. These cultures were designated Martiki-R (Rough) and Martiki-S (Smooth) in accordance with their respective colonial mor- phology. Other bacteria used in this investiga- tion were obtained from the American Type Culture Collection as follows: A. lipoferum ATCC 29707, A. brasilense ATCC 29145 and Azotobacter paspali ATCC 23833. Culture Medium—All bacteria were main- QQ tained with bi-monthly transfers on agar slants of a nitrogen-free malate medium similar to that employed by Haahtela et al. (4). Each compo- nent of this medium was autoclaved and main- tained separately in 10X concentration as a stock solution with the exception of the agar which was dissolved in 880 ml of distilled water and autoclaved. Next, 10 ml of each sterile stock solution was added aseptically to the agar suspension. These additional components of the final medium were: biotin, 100ug; pyridoxine- HCL, 200 pg; Na,MoO,.2H,0, 0.005 g; KH,PO,, 0.4 g; K,HPO,.3H,0, 0.13 ; NaCl, 0.1 g; CaCl,.2H,0, 0.2 g; MgSO,.7H,0, 0.2 g; FeSO,.7H,0, 0.2 g; DL-malic acid, 5 g; CaCO, 0.5 g and 40% w/v KOH solution added to a final pH of 6.8-7.0. Growth and Preparation of Cultures for Ethylene Assays—The microorganisms used in this study were grown at 32°C for 72 h on nitrogen-free agar slants. Cells were washed from the slants using nitrogen-free broth, col- lected by centrifugation (5000 x g for 10 min) and suspended in fresh nitrogen-free broth. The culture was then adjusted to a density of 100 klett units (approximately 1.2 x 10° cells per ml) using a Klett-Summerson Colorimeter. One- fourth ml of this cell suspension was then in- oculated into 6 replicate 13.5 ml serum vials each of which already contained 3.25 ml of nitrogen-free agar medium. While immersed in an ice bath, each vial was next flushed with glasswool filtered nitrogen at a rate of 400 ml/min for 5 min. following this procedure, a specified volume of nitrogen wes withdrawn from the vial and replaced with oxygen. In vials containing A. lipoferum, 0.85 ml of oxygen was added; in vials with A. brasilense, 1.28 ml of oxygen was added; and for vials with 34 Azospirillum Nitrogen Fixation in Kentucky Coal Mines — Mardon and Rothwell Azotobacter paspali, 0.43 ml of oxygen was used (5, 9). Cultures were incubated at 32°C for selected time periods (Table 1 and 2) after which 1.0 ml of the gas phase in each vial was removed and replaced with 1.0 ml of acetylene (6). After the addition of acetylene each vial was subse- quently incubated for an additional 3 h at 32°C then assayed for ethylene. Acetylene Reduction (Ethylene) Assay—All assays for acetylene reduction were done on 0.5 ml samples taken from the reaction vessels with mininert valves (13). The ethylene produced was determined by using a varian 2700 gas chromatograph with a one-eighth inch, 80/100 mesh Porapak-R column, 2.8 m in length and a flame ionization detector, as outlined by Smibert and Krieg (11) and Haahtela et al. (4). All data are expressed as nanomoles of ethylene produced/mg protein/h. Protein Assays—Cells were washed from the reaction vials with 0.5 ml of IN NaOH. After digestion at 23°C for 24 h with NaOH, culture extracts were assayed for protein, using bovine serum albumin as a standard (7). Table 1.

Each value is the mean + standard deviation of 6 replicate vials. RESULTS AND DISCUSSION As shown in Table 1, after 15h and continu- ing throughout the incubation period, the rate of acetylene production was markedly higher for Martiki-S than for Martiki-R. Although low in comparison with Martiki-S, in this study, the rate of acetylene reduction by Martiki-R was nevertheless comparable to that previously reported for Azospirillum lipoferum (1, 5). David and Fay (2) have reported the preincubation or constant incubation of nitrogen-fixing microorganisms with acetylene for longer than 3.0 h may deplete cellular nitrogen and subse- quently depress the nitrogenase system, resulting in artificially high estimates for acetylene reduction. To determine if such derepression might be the cause of high rates of nitrogen fixation in our Martiki-S cultures the acetylene pulse was reduced to 1.0 h (9). The subsequent rates of acetylene reduction under these conditions were still comparable to those shown in Table 1, indicating that for the Martiki-S culture the high values for acetylene reduction were not due to excessive incubation periods with acetylene. Comparison of maximum rates for acetylene reduction by all bacterial species tested (Table 2) indicate that nitrogen fixation by Martiki-S was approximately 37-fold greater than Azotobacter paspali and about 100 times greater than A. brasilense, A. lipoferum ATCC 29707, and A. lipoferum Martiki-R. With the exception of A. lipoferum Martiki-S the max- imum rates of acetylene reduction obtained for the cultures used in this study (Table 2) are all comparable to values reported in the literature for Azotobacter and Azospirillum isolates (2, 3, 9). Some investigators have observed high rates of nitrogen fixation with Enterobacter ag- glomerans and Klebsiella penumoniae (8); however, these values are 5-10 fold lower than those observed for Martiki-S.

Three hours after the addition of acetylene the vials were assayed for ethylene. *Values represent nanomoles of ethylene formed/mg protein/h dur- ing the period of maximum ethylene formation. Each value is the mean + standard deviation of 6 replicate vials. When the microorganisms used in this study were incubated beyond 27 h and then pulsed with acetylene, ethylene formation decreased with increasing incubation times. After 96 h the Martiki-S culture still retained a substantially greater capacity for acetylene reduction. Trans. Kentucky Academy of Science — 46(1-2) 35 Perennial grasses are commonly a part of the grass legume mixture used to stabilize the surfaces of recently graded minesoils. Although symbiotic nitrogen-fixers undoubtedly represent the major factors in maintenance of the nitrogen economy on minesoils, the rapid availability of the fixed-nitrogen from asymbiotic bacteria may be of considerable importance in the early growth and development of grasses on these sites. It would be premature to speculate upon a biochemical basis for the high rate of acetylene reduction we observed with the Martiki-S culture. However, the efficiency of the isolate as demonstrated in this study underscores the need for continued investigations into the factors af- fecting the nitrogen-fixing capability of Azospirillum found in association with reclamation plants.

Cromley Department of Geography, University of Connecticut Storrs, Connecticut 06268 Thomas A. Arcury Center for Developmental Change, University of Kentucky Lexington, Kentucky 40506-0027 ABSTRACT This paper examines the impact of rural manufacturing decentralization on the occupational structure of rural areas that are not hosting nonmetropolitan industries but are within the labor shed of these factories. Focusing on the manufacturing workers of one such county, changes in occupation structure are related to the development of manufacturing industries in adjacent nonmetropolitan counties. The relationship between manufacturing employment and agriculture, the traditional dominant employer, is tested and the availability of agricultural work is not found to have an impact on the occupational structure of manufacturing workers. INTRODUCTION A major problem accompanying the in- dustrial development of capitalist economies has been unbalanced regional economic growth (1, 2). While regional disparities in the United States have different forms at various geographical scales, most have their roots in the fundamental transformation from a predominantly rural agricultural society to an industrialized urban one and the separation of worker from the land. Between 1920 and 1970, the rural population of the United States re- mained constant at 54 million while the urban population increased almost threefold to 149 million in 1970 (3). Improvements in farming technology and the mechanization of agriculture had reduced the need for farm laborers. Nonmetropolitan nonfarm industries were not able to absorb the excess population, thus creating a surplus farm population. The result was a large rural to urban migration stream for most of this century. Metropolitan centers became the vanguard of population and economic growth while rural areas became pockets of poverty, high unemployment, and heavy out-migration. The major policy measures for improving this imbalance have tried to integrate the lag- ging rural periphery with the economic oppor- tunities of the cities (4, 5). Growth-center strategists maintained that the best hope for rural areas lay in the ‘trickling-down’ of economic growth impulses from metropolitan centers (6, 7). This view was supported by the fact that nonmetropolitan regions adjacent to a Standard Metropolitan Statistical Area (SMSA) or part of its daily system were growing at rates 36 higher than the rest of the nonmetropolitan periphery (8, 9). Recently it has been noted that nonadjacent counties in the rural periphery grew during the 1970's at a rate that exceeded most large metropolitan centers and the national average (10). A major impetus for the population and economic reversal of many nonmetropolitan places has been the decentralization of industry from the urban core to these regions (11, 12, 13). The filter-down of branch plants has been the primary force behind the industrial growth of Many nonmetropolitan communities (14, 15). Many manufacturers are establishing factories in rural areas seeking lower labor costs as wages have become a more important component of total costs. Rural residents are still being transformed from agricultural to industrial workers but in many instances no longer need to migrate to an SMSA and can remain closer to their farms. The level of this industrial movement is not uniform throughout nonmetropolitan America. There exists a place hierarchy within the in- termetropolitan periphery whose settlements range from non-urban hamlets to large towns almost equal in size to small metropolitan centers. Branch plants tend to locate in the larger rural towns, while indigenous firms predominate in smaller hamlets (14, 16). Because firm stability is greater among branch plants than indigenous firms, employment is usually more stable in the larger rural towns. In- termetropolitan centers are thus emerging as foci for employment opportunities (17, 18). However, the relocation of industry and retail Trans. Kentucky Academy of Science — 46(1-2) activity in the periphery does enable places lower in the settlement hierarchy to participate more fully in the industrial economy as the need for commuting long distances to large metropolitan centers is reduced (19, 20). There is also evidence that the labor sheds for branch plants are larger than their indigenous counter- part. Regardless of plant size or industrial type, a larger proportion of Kentucky branch plant employees commute from outside the county in which the plant is located (21). This indicates that branch plants, located in larger rural towns, have a strong impact on the surrounding hinterland. It also implies that the hinterland residents are an important labor source for the movement of manufacturing to nonmetropolitan urban centers. It has been suggested that rural areas have a wage advantage due to the presence of a class of workers, part-time farmers, who derive income from a supplementary source, farming (22). Alternatively, it has also been suggested that the presence of manufacturing has made it possible for individuals involved in small scale and part-time agriculture to maintain two com- plementary sources of income (20). Most research has examined the economic and social impact of manufacturing on these larger urban communities, but few have studied the spread effect of this industrialization on more “rural” counties, and especially the labor relationship between farming in these areas and urban industrial jobs. This paper examines the hypothesis that rural communities that do not have any manufacturing plants, but are located in the vicinity of nonmetropolitan places that are hosting industrial growth, are experiencing an economic metamorphosis of their own. The transformation of the occupational structure of these areas is occurring without being strongly allied with the daily commuting system of an SMSA. Additionally, it examines the linkages that exist within the labor force between the transitional employer, agriculture, and the new industrial factories to determine whether by sup- plementing their income as part-time farmers, manufacturing workers in these areas are able to work for lower wages, reinforcing the wage disparities between urban and rural regions. STUDY AREA AND DATA Robertson County, Kentucky has been selected as a suitable study area for examining these hypotheses. The nonmetropolitan coun- ties of Kentucky have been part of the nation- wide growth of rural industry (14, 16). In 1980, Robertson County was one of only 3 counties in the state that did not host any manufacturing activity, branch or indigenous. The other 2 37 counties are located in the heart of the Eastern Kentucky coal field, whereas Robertson County is located in the northeast part of the Kentucky Bluegrass Region (Figure 1). Although the Ap- palachian Kentucky region has experienced re- cent growth in manufacturing, its overall manufacturing employment still lags behind the central and western portion of the state. Manufacturing is especially weak in the coal producing counties of Eastern Kentucky where there is strong competition with the higher min- ing wages, and poor access to the highway system. poe { LAWS 2 Pie Flemingsburg \yess TaN sicaght as ate Gila Neo Le Mn i Carlisle / if Olive « fe ill / s ils \ / o \Georgetown > Aes rae i) SSA Figure 1: Location of Robertson County, Kentucky. Robertson County is also removed in prox- imity from major metropolitan centers. The county is approximately 50 miles northeast of Lexington, Kentucky, and the same distance southeast of Cincinnati, Ohio, the 2 closest SMSAs. The county does not have direct access to the Interstate Highway System, (the closest, 1-64, and I-75, are 50 miles distant), railway lines, or commercial bus lines. The major transportation routes are US 62 and US 68 which give the population direct access to the county seats of surrounding counties and to Lexington. Finally, Robertson is one of the most non- urban counties within the state. It is Kentucky’s second smallest county with an area of 101 square miles, and has the smallest county population with 2,265 persons in 1980. Mt. Olivet, the county seat, has a populaton of about 400 persons and is the only incorporated town in the county. The size of the county’s population has declined steadily over the past century. From a high of 6,131 persons in 1880 (23) it fell to 2,149 persons in 1970 with an in- crease to 2,265 persons in 1980. The population decline is due to high-level out-migration. 38 Nonmetropolitan Industrialization in Kentucky — Cromley and Arcury The primary data for this study were ob- tained from a general purpose survey of Robert- son County that was conducted between June 1 and August 30, 1980. This door-to-door survey attempted to enumerate the residents of every household in the community. Data on earlier occupational and employment patterns have been abstracted from U.S. Census reports. In- formation on the presence and types of manufacturing industries in Robertson and sur- rounding counties are derived from the Ken- tucky Directory of Manufacturing. OCCUPATIONAL CHANGE Historically farming has been the predomi- nant occupation in Robertson County. The 1870, 1880, and 1900 Censuses show that over 90% of the county's work force was employed as farmers. Those who were not farmers were employed in agricultural support occupations such as plowmaker and blacksmith. Other documentary sources and ethnographic data in- dicate that until the mid-1920s subsistence farm- ing was the major pursuit. Farm produce in- cluded a wide variety of items needed for home consumption such as_ vegetables, wheat, sorghum, and honey. Since the 1920s, farming has changed to cash cropping with tobacco and corn being the major crops while some farmers maintain large beef and dairy operations. The portion of the work force associated with farming occupations has greatly decreased since 1930. In 1930, 70% of the work force was employed as farmers or farm managers while 13% held other agricultural jobs (24, p. 947). During the next 30-year period, these figures slowly declined until only 56.7% were employed as farmers or farm managers and 7% as agricultural workers in 1960 (25, pp. 19-234). The total number of farms decreased from 826 in 1930 to 515 in 1959. Since 1960, the decline in farming has been more rapid. By 1970, only 40.8% of the work force was employed in any type of farming occupation, and this figure had decreased even further, to only 23.7% in 1980 (26, pp. 19-432). Only 356 farms were still in operation in Robertson County in 1978 (27.).! The total size of the work force also decreased from 1094 in 1930 to 728 workers in 1960. This decline is associated with the ab- solute losses occurring in the agricultural sector without other sectors expanding their job offer- ings. A Kolmogorov-Smirnov test showed a significant shift in the occupational structure of the labor force during each decade since 1960 ’ The decrease in the number of farms between 1930 and 1978 may actually be less than the figures stated. The U.S. Bureau of the Census raised the farm income levels needed to be defined as a farm in 1959 and in 1978. (Table 1). The size of the work force also in- creased even though agriculture was still ex- periencing a decline. During this latter period other sectors of the economy were expanding faster than agriculture was declining. Every oc- cupational group increased except those that are farm-related. Operatives and kindred workers experienced the greatest absolute in- crease — from 38 workers in 1960 to 184 in 1980. Clerical and kindred workers, salesworkers, ser- vice workers, and laborers also had a substan- tial increase in numbers. In general, the occupa- tional change that has occurred since 1960 sug- gests that other activities, such as manufactur- ing and retailing, are replacing agriculture as the dominant employment for Robertson Coun- ty residents.

Kentucky Academy of Science — 46(1-2) 39 THE DISTRIBUTION OF MANUFACTURING EMPLOYMENT The most striking facet of occupational change in Robertson County has been the emergence of manufacturing as an important source of employment although no manufactur- ing firm has actually established a plant there. In 1960, there were fewer secondary sector employees (only 1.1% of the work force) in the couniy than there were before 1900. At that earlier time some manufacturing shops existed to produce tools, wagons, and other goods for local consumption. These cottage industries soon lost their market due to increasing external competition. In 1980, the 21.5% of the Robert- son County work force employed by manufac- turing firms commuted to places outside the county for their jobs. The spatial distribution of these commuters exhibit a strong distance decay function and directional bias (Table 2). Seventy five % of the manufacturing work force commute to another nonmetropolitan county directly adjacent to Robertson, while only 7.5% commuted to a tier of counties once removed. The remaining com- muters are scattered over a wide range of destinations. The distance decay effect is similar for both male and female workers. Females were more selective in their destination outside the adjacent ring of counties. Sixteen of the 20 female workers commuted to either Falmouth in Pendleton County or Cinncinnati, Ohio, while male workers were evenly distributed over the longer trips. This reflects the greater job oppor- tunities for male workers. The highway system around Robertson County is responsible for a strong direction bias toward those settlements that are directly con- nected to Robertson by either US 62 or US 68 (see Figure 1). Located on these 2 routes, Maysville, Carlisle, and Cynthiana receive the overwhelming majority of Robertson workers. Bracken and Fleming Counties have relatively poor connector routes, and only 2 workers com- mute to either of these counties although both are adjacent to Robertson. The spatial distribution of commuting is also strongly influenced by the arrangement of employment opportunities in neighboring nonmetropolitan counties. Robertson County is not dependent on major metropolitan centers for industrial jobs but rather on other nonmetropolitan areas. Only 14% commuted to a county that is part of a Standard Metropolitan Statistical Area (SMSA) while 82% commuted to another nonmetropolitan county. Robertson is at the bottom layer of the regional settlement hierarchy. Its rapid increase in manufacturing employees is a result of the nationwide move- Table 2.

Of the 16 firms located in the nometropolitan centers to which Robertson residents commute, only 4 were established before 1960. The majori- ty were estabished in the boom period of nometropolitan industrialization during the late 1960s and early 1970s. Nine of these firms are branch operations of an external parent com- pany, while 7 are indigenous or locally controll- ed. The indigenous firms account for only 39% of those Robertson County manufacturing employees who commute to nonmetropolitan industry. This new industry has resulted in a heavy concentration of employment opportunities within relatively few Standard Industrial Classification (S.I.C.) groups among the 6 im- mediate neighhboring counties. Almost 91% of the total manufacturing work force employed in these counties are distributed among 8 S.I.C. groups and are low technology (Table 3). With respect to individual counties, only Harrison and Mason Counties, the two largest employing counties, have a reasonably uniform distribution of employment over these eight groups, while the majority of jobs in the other counties are centered in a single S.I.C. group. 40 Nonmetropolitan Industrialization in Kentucky — Cromley and Arcury Table 3: Major Standard Industrial Classification Group Employment Distribution in Robertson County's Neighboring Counties S.1.C.

Most residents work in a plant that produces either textile mill products, the largest regional employer, or fabricated metals, the third largest employer. The lack of reasonable connector links to Fleming and Pendleton Coun- ties is probably responsible for few residents be- ing employed in S.I.C. 31, leather and leather products, the second largest regional employer. This distribution is also sharply divided by sex. Typical of many rural areas of the South, the majority of the female workers commute to a textile mill, the lowest paying S.I.C. industrial group in Kentucky. Among males, fabricated metals is clearly the dominant employer while non-electrical machinery is a distant second. Besides the predominance of low technology firms, a concern is whether in- dustries will contribute to the development of local entrepreneurial skills. Branch operations in general contribute relatively few management opportunities for host communities (28). Rural counties that are only part of the labor shed should receive even fewer white collar jobs. For Robertson County, only 3 individuals were employed in a professional or managerial oc- Table 4.

MANUFACTURING AND AGRICULTURAL EMPLOYMENT LINKAGES Although manufacturing has attained an importance as an employer in Robertson County almost equal to agriculture, this change has not created 2 separate classes of workers. Given the dominance of agriculture as the primary employer in the recent past, many currently employed in manufacturing once farmed or were reared in farming households. Some manufac- turing employees who do not farm do own land and a tobacco base which they lease to others. Most importantly, many individuals and households obtain portions of their incomes from both manufacturing and agricultural oc- cupations. Of the 186 manufacturing employees, 44 stated that they also farmed as a secondary occupation. Only one of these 44 was female. Most part-time farmers have primary occupa- tions as operatives. However, when a Chi- Square test was performed to see if a greater proportion of manufacturing operative sup- plemented their incomes with part-time farm- ing than did other manufacturing employees, no significant correlation was found (Table 5).

The occupations of the majority of the manufacturing workers in these manufacturing- agriculture households is that of operative. Again, a Chi-Square test performed to see if a greater proportion of manufacturing operative households supplemented their income with farming than did other manufacturing employee households showed no significant correlation. DISCUSSION One of the predominant industrial trends during the last 2 decades has been the move- ment of manufacturing from metropolitan to nonmetropolitan regions. The labor mobility of rural areas in former times is now being re- placed by capital mobility from metropolitan regions as the mechanism for resolving regional imbalances of labor supply and demand (29). This phenomenon has changed the rural land- scape by directly stimulating the growth of nonmetropolitan urban places; some places have even been elevated to metropolitan status. Just as important, rural communities which do not have manufacturing plants, but which are located near nonmetropolitan places that are hosting industrial growth, are also experien- cing economic change and this ecomomic change is occurring without strong alliance wth the daily commuting system of an SMSA. This is supported by the Robertson County situation. The industrial transformation of its occupational structure has occurred without being strongly allied with the daily urban system of an SMSA or having any manufacturing firms of its own. Past studies have noted that job leakage from host communities have regionalized the impacts 42 Nonmetropolitan Industrialization in Kentucky — Cromley and Arcury of these nonmetropolitan manufacturing firms. Due to the perspective of these studies, examin- ing the commuter sheds of specific firms, the full impact of the rural manufacturing phenomenon on participating communities has not been presented. The Robertson County situation is an example of the pervasiveness of rural in- dustrialization. While it has not attracted any manufacturing firms, it is within the commuting sheds of several nonmetropolitan firms in the surrounding counties. Commuting has become the adaptive mechanism by which this formerly agricultural area has added a new mode of economic activity. Different analysts have suggested that the mix of agricultural and manufacturing employ- ment is both the cause and effect of the nonmetropolian industrial phenomenon. In Robertson County a high percentage of manufacturing workers do farm on a part-time basis, or live in households in which agricultural wages are part of the family income. The availability of agricultural income may allow some rural manufacturing workers to earn a bet- ter livelihood given the relatively low wages paid by nonmetropolitan manufacturers. This study does not support the hypotheses that such sup- plemental agricultural income is necessary for the economic survival of the nonmetropolitan manufacturing worker. The majority of these workers do not reside in households with agricultural income, nor are there significant differences among the manufacturing workers by occupational group in the proportion with agricultural income. Agricultural income may offset the cost of extended commuting for some, but it probably has no relationship to the wage- rates of these workers.

RH - Demography in Kentucky Raccoons — Smith and Kennedy Demography of the Raccoon (Procyon lotor) at Land Between The Lakes Richard A. Smith and Michael L. Kennedy Memphis State University, Memphis, Tennessee 38152 ABSTRACT Sex ratio, age structure, and litter size of a population of raccoons (Procyon lotor) were studied from December 1980 through November 1981. The study area was land Between The Lakes in Stewart County, Ten- nessee, and Lyon and Trigg counties, Kentucky; 145 specimens were examined. The population was 49.7% male and 50.3% female. Twenty per cent of the animals were juvenile, 13.3% subadult, 25.0% adult, and 41.7% old adult. Average litter size was determined to be 2.9. INTRODUCTION The raccoon (Procyon lotor) has been the subject of many biologic investigations. Since the animal is an important game species, many previous studies have been directed toward questions related to its management. Investiga- tions directed toward collection of data concern- ing sex ratio, age structure, litter size, parasites, and other features have been numerous. Lotze and Anderson (1) summarized much of the available literature. However, demographic in- formation tends to vary between geographic areas for raccoons; therefore, management in- formation obtained for one region may not be applicable to management programs in others. With the exception of Dew (2), little infor- mation is available concerning population characteristics of P. lotor in western Tennessee and western Kentucky. The purpose of this study was to examine the demographic features of sex ratio, age structure, and litter size associated with a raccoon population in western Tennessee and western Kentucky. This study provides addi- tional baseline data for raccoon management in Kentucky and Tennessee. MATERIALS AND METHODS The study was conducted at Land Between The Lakes (LBL) in Stewart County, Tennessee, and Lyon and Trigg counties, Kentucky. LBL is a 170,000— acre peninsula with approximately 482 km of shoreline between Kentucky Lake on the west and Lake Barkley to the east. The habitat was predominantly upland hardwood forest. Some old fields and agricultural lands were within the study area. Collections from December 1980 through November 1981 yielded 145 animals (72 males; 73 females). Seasonal samples were as follows (male sample size is given first): winter—8,13; spring— 20,15; summer—27,25; fall—17,18. Seasonal data were incomplete for 2 females. Most animals were collected by gun, with the use of dogs or spotlighting from a boat or truck. 44. Animals were transferred to the Department of Biology, Memphis State University, where they were stored and later examined. Gross examina- tion was conducted for age and sex determina- tion. Specimens were aged as juvenile (class I, N = 12), subadult (class II, N = 8), adult (class III, N = 15), or old adult (class IV, N = 26) follow- ing Junge and Hoffmeister (3). Reproductive tracts were removed and examined. Average lit- ter size was based on counts of embryos and sites of placental attachment (placental scars) from 26 females. Reproductive tracts were stored in 10% formalin. Raccoon skeletons, skins, and preserved material were deposited in the Memphis State University Museum of Zoology. Individual data for specimens and a map of localities are presented in Smith (4). RESULTS AND DISCUSSION Of the raccoons examined, 49.7% were male and 50.3% female. This sex ratio coincides with those reported for Tennessee specimens by Dew (2) and Woods (5). Studies conducted in other geographic areas (6, 7) also reported, in general, a 100:100 sex ratio. Cummingham (8) and Johnson (9) noted that sex ratios of rac- coons collected with dogs and guns may be less biased than those of animals caught in traps. Since specimens in the present study were col- lected primarily with dogs and guns during all seasons, the sex ratio determined should reflect an accurate estimate of population structure in relation to sex. Schwartz and Schwartz (10) in- dicated that the sex ratio of raccoons tends to vary with the population level. When the population is increasing, there are more females than males; when it is decreasing, there are more males. Thus, based on sex-ratio results, the LBL population was approximately stable during the study period. However, hunter- success data (raccoons/hunter/night) indicated the population to be decreasing at this time (un- publ. rep., TVA, Golden Pond, KY, 1982). The Trans. Kentucky Academy of Science — 46(1-2) 45 stability of the LBL raccoon population during the study is uncertain and such population characteristics are in need of additional study. The age structure of the raccoons taken was 20.0% age class I, 13.3% age class II, 25.0% age class III, and 41.7% age class IV. These results differ from previously reported age structures for raccoons. Whitney and Under- wood (11), Sharp and Sharp (12), Johnson (9), and Schwartz and Schwartz (10) reported highest percentages of young animals; percen- tages decline with age. Age structure seen in the present study probably reflects methods and times of sampling. Since juveniles make up the majority of harvest during the hunting season, this would leave fewer juveniles on the study area during the winter and spring. If summer and fall mortality is high in the first year animals and low in older animals as suggested by Smith (4), one would expect to find greater numbers of older animals in the population during the winter and spring. From 26 raccoons which contained placen- tal scars, litter size results were as follows: 2, N = 8; 3, N = 14;4,N = 3;5, N = 1. Sanderson (13) showed that raccoon placental scars are reliable indicators of the number of young pro- duced. Average litter size for the LBL population was determined to be 2.9. This is greater than the 2.3 reported by Dew (2) for western Ten- nessee but equal to the 2.9 he reported for eastern Tennessee. The 2.9 value has also been reported in Illinois by Sanderson (13). Johnson (9) indicated a 2.2 litter size for Alabama rac- coons. Litter size in raccoons apparently varies geographically, increasing with northern latitudes. LITERATURE CITED 1. Lotze, J., and S.

Department of Biological Sciences and The Hancock Biological Station, Murray State University, Murray, Kentucky 42071 ABSTRACT A survey of the phytoplankton (exclusive of diatoms) in the lower portion of Kentucky Reservoir was con- ducted from September, 1982 to September, 1983. One hundred and fifty-six species, varieties, and forms representing 59 genera were identified. The green algae dominated the algal flora in all seasons but were most numerous in the summer. Blue-green algae were most abundant in summer and fall, while euglenoids reached their peak numbers in summer. The number of dinoflagellates remained relatively low throughout the year. INTRODUCTION The algal flora of Kentucky Reservoir has been the subject of relatively few investigations. The only published records of Kentucky Reser- voir phytoplankton are those resulting from lim- nological studies of Anderson Creek and Vickers Creek embayments (1, 2). The dominant phytoplankton at other locations in Kentucky Reservoir are presented in unpublished reports (3-5) from water quality surveillance programs which included this aquatic system. However, these publications and reports focused primarily on identifications of taxa to the generic level; thus, we have little information on the species composition of the algal flora in Kentucky Reservoir. In this study we attempted to identify the phytoplankton species which occur in the lower portion of Kentucky Reservoir. It is part of an overall effort to gain more insight into the com- position of the primary producers of this surface water resource. Diatom identifications are still in progress; thus, these algae are not included. COLLECTION SITES Fourteen collection sites were established between Tennessee River miles 43.3 and 49.0 on Kentucky Reservoir (Fig. 1). Two sites were located in each of 2embayments on the western (Anderson Creek Embayment, Snipe Creek Em- bayment) and eastern (blockhouse Creek Em- bayment, Turkey Creek Embayment) sides of the reservoir. Six collection sites were estab- Partial! funding provided by Committee on Institutional Studies and Research, Murray State University * Address for correspondence lished in the main portion of the reservoir and were situated upriver, between and downriver from the embayments. Water samples were collected from each site 10 times from September, 1982, to September, 1983. The samples were taken with a plastic bucket at the surface and with a Kem- merer bottle at the mid-water column and 0.5 m from the bottom. Equal volumes of the samples were mixed, transferred to one-liter plastic bot- tles, and placed on ice for transport to the laboratory. Species identifications were made through microscopic observations of raw samples and from subsamples concentrated by centrifugation at 5,000 x g for 5 minutes. CHECKLIST The nomenclature in this report follows that of Bold and Wynne (6). One hundred and fifty six species, varieties’ and forms, representing 59 genera were identified (Table 1). Of these, 37 species and three genera had not been previous- ly reported as occurring in Kentucky (7-17). Species of green algae dominated the phytoplankton assemblages in all seasons but were most numerous in the summer (Table 2). The greatest number of species were in the Chlorellales, due primarily to those in the genus Scenedesmus. Species of blue-green algae were most abundant in summer and fall while euglenoid species, especially trachelomonads, reached their peak numbers during the summer. The number of dinoflagellates remained relatively low throughout the year.

RH - Root Phenols in Kentucky Plants — Creek and Wade Excretion of phenolic compounds from the roots of Festuca arundinacea, Eragrostis curvula, and Lespedeza striata. Robert Creek Department of Biological Sciences Eastern Kentucky University Richmond, Kentucky 40475 and Gary L. Wade Northeastern Forest Experiment Station U.S. Forest Service Berea, Kentucky 40403 ABSTRACT Festuca arundinacea, Eragrostic curvula, and Lespedeza striata were grown hydroponically using a con- tinuous circulating system in which root exudates were collected in columns containing XAD-4 resin. The ex- udates were separated into neutral, acidic, and basic fractions. Lettuce radicle bioassay showed only the neutral fractions to be inhibitory. Analysis of the neutral fractions by paper chromatography, TLC, and gas chromatography indicated the presence of 5 inhibitory compounds, which were tentatively identified as the phenolic compounds cinnamic acid, ferulic acid, gallic acid, gentisic acid, and syringic acid. INTRODUCTION Allelopathy, chemical interference by one plant species with another, is a widespread phenomenon. It has been documented in forest, grassland, freshwater, marine, and agricultural ecosystems. Allelochemics, chemical com- pounds produced by a plant species, may operate directly on another plant species, in- directly on its symbiotic organisms, or through modification of the ecosystem (1). Reforestation of surface-mined lands now requires planting trees in an herbaceous ground cover. Frequent problems with tree survival and growth under these conditions suggest that allelopathy may be a factor in herb-tree competition in some situations. Allelopathy has not been demonstrated on surface-mine spoil, but this is due more to a lack of research than to negative research results. A necessary first step is to determine if species commonly used in land reclamation are allelopaths. Identification of the allelochemics produced together with their known effects on different organisms allows potential problems to be identified and studied. Accordingly, this study investigated allelochemic production by three herbaceous species commonly used as ground cover on surface-mined lands, tall fescue (Festuca arun- dinacea Schreb.), weeping lovegrass (Eragrostic curvula Nees.), and Kobe lespedeza (Lespedeza striata (Thunb.) H. & A.). Water extracts of tall fescue, weeping lovegrass, and Kobe lespedeza cause a delay in germination of crown vetch (Coronilla varia L) and crimson clover (Trifolium incarnatum L.), but later radicle growth is not significantly in- hibited (2). Litter of tall fescue inhibits growth and nitrogen fixation in black locust (Robinia pseudo-acacia L.), red clover (Trifolium pratense L.), and black alder (Alnus glutinosa (L.) Gaertn.) (3), and germination, hypocotyl growth and root growth of birdsfoot trefoil (Lotus cortniculatus L.) (4). Tall fescue genotypes differ in inhibition of birdsfoot trefoil and red clover (5). Leachates of red fescue (F. rubra L.) roots are inhibitory to root and shoot growth of forsythia (Forsythia intermedia Spaeth.) (6). Sericea lespedeza (L. cuneata L.) residues in the soil give rise to a number of phenolic compounds (7). None of the above studies attempted to identify toxins released into the soil by living plants. MATERIALS AND METHODS Plant Growth And Extraction.—A_ con- tinuous root exudate collecting system developed by Tang and Young (8) was used to grow donor plants and to collect root exudates. The containers were 3.79 L bottles with bottoms removed. The bottles were placed neck down, stoppered, and filled with a 2 cm layer of pebbles over which was added a mixture of washed silica sand and pebbles. The bottles were then wrap- ped in aluminum foil and autoclaved. 51 52 Root Phenols in Kentucky Plants — Creek and Wade Seeds of tall fescue, weeping lovegrass, and Kobe lespedeza obtained from commercial sources were sown on the surface of the sand and covered with a layer of sterile sand. They were watered every other day with 0.1 strength Hoagland solution and with additional distilled water as necessary. When the plants were 2 cm tall, the circulating attachments and columns containing XAD-4 resin, which absorbs organic compounds, were connected to the bottoms of the containers. The water level in the sand culture was adjusted to within 1 cm of the sur- face with distilled water and replenished daily as needed to maintain this level. One hundred ml of 0.1 strength Hoagland solution was added once a week. The solution was circulated at an approximate rate of 500 ml/hr. All plants were grown under greenhouse conditions during the spring and summer without extension of the photo period. Temperatures ranged from 20° to 30°C. Because greenhouse glass does not pass most of the ultraviolet portion of sunlight (9), supplementary ultraviolet light was added four hours per day using Westinghouse FS-40 lamps with 15 mil mylar filters to remove wavelengths less than 320 nm. Lamp to pot distance was 1 m. Pot controls did not contain plants, but they were treated identically otherwise. The plants were grown for 4 weeks. Then the columns were removed, washed with 2 L of distilled water and eluted with 100 ml of diethyl ether. The eluates from the columns of 5 replicates of each species were pooled, and the ether was evaporated to dryness under reduced pressure. The dried residue was taken up in 50 ml of water, pH was adjusted to 6.0, and the solution was extracted 3 times with 100 ml methylene chloride. The extracts were com- bined, dried over anhydrous magnesium sulfate and concentrated to 25 ml in vacuo. Final con- centration to 3 ml was carried out under a stream of nitrogen. This final concentrated material represented the neutral fraction. The remaining aqueous fraction was acidified to pH 2.0 with 1 N HCl and again extracted with methylene chloride to give the acidic fraction. The acidified aqueous fraction was then ad- justed to pH 11.0 with 1 N NaOH and extracted with methylene chloride to give the basic frac- tion. The acidic and basic fractions were con- centrated to a final volume of 3 ml. Chromatography—Two hundred ul aliquots from the neutral fractions were streaked on Whatman No. 3 MM filter paper and developed in the descending mode using a 2 per cent (v/v) glacial acetic acid solvent system. The chromatograms were dried and cut into 10 equal segments (Rf/10). Each segment was eluted with 5 ml of methanol, then reduced to a final volume of 1 ml and bioassayed as described below. We used thin layer chromatography (TLC) on microcrystalline cellulose plates with phosphor (Alltech Associates) with 2 per cent glacial acetic acid as the solvent system. Spots were visualized under ultraviolet light (253.7 and 375.0 nm) and after spraying with diazotized p-nitroanaline (10). Standards were run with all chromatograms. Biossay.—Aliquots (100 and 50 ul) of the neutral, acidic, and basic fractions were added separately to Whatman No. 3 MM filter paper contained in 5.5 cm diameter petri dishes. The solvent was evaporated and 0.2 ml of distilled water added to the filter paper. Five 48-hr old lettuce seedings (Lactuca sativa L.) were added to each petri dish. After the seedlings were grown in darkness for 48 hours at room temperature, about 21° C, the lengths of their radicles were measured. All bioassays were car- ried out in triplicate, and results were expressed as per cent of inhibition relative to the pot con- trols. Student’s t-test was used to determine significance of treatment differences. Because only the neutral fraction showed significant ef- fects on lettuce radicle growth, the acidic and basic fractions were not tested further. Gas-Liquid Chromatography.—The GLC analysis was made with a Varian Model 2840 chromatograph equipped with a flame ioniza- tion detector. Nitrogen was used as the carrier gas at a flow rate of 40 ml/min. A 20 mm (I.D.) x 2 m glass column was packed with 3 per cent SP-2250 on 100/120 mesh Sueplcoport and pro- grammed from 150° to 220°C at a rate of 8° C/min. The injector and detector were main- tained at 250° C. Trimethylsilyl derivatives were prepared by evaporating 1 ml of the neutral extract to dryness under nitrogen. One-half ml of Tri- Sil/BSA formula D (Pierce Chemical Co.) was added to the vials and solution allowed to sit for one hour before GLC analysis. The phenolic standards were prepared in a similar manner. RESULTS Only the neutral fractions of the root exudates from the 3 donor species were toxic to lettuce (Table 1). The 100 yl dose of each of the 3 donor species significantly inhibited growth of lettuce radicles. Tall fescue was the only donor whose exudates were significantly inhibitory at a 50 ul dose. The Rf/10 bioassays of the 200 pl aliquots from the neutral fractions of tall fescue significantly inhibited growth of lettuce radicles in segments 0.2-0.3 and 0.5-0.6 (Table 2). The 0.3-0.4 seqment from weeping lovegrass and the 0.3-0.4 and 0.5-0.6 seqments from Kobe lespedeza also significantly inhibited lettuce Trans.

Other unidentified compounds were released by the 3 donor species. The Rf value of 0.30 for ferulic acid in paper chromatography indicates that the spot pro- duced in the Rf/10 bioassay would have been split between segments 0.2-0.3 and 0.3-0.4. Both of these segments showed inhibition of lettuce radicle growth, but it was only significant in seq- ment 0.2-0.3 from tall fescue and seqment 0.3-0.4 from weeping lovegrass and Kobe lespedeza. The Rf value for gallic acid fell in the middle of segment 0.3-0.4 but GLC indicates that only weeping lovegrass produced this com- pound. Segment 0.40.5 containing syringic acid, produced only by Kobe lespedeza, did not show significant inhibition of lettuce in this test. Gentisic acid, produced by all 3 species, had an Rf value of 0.59 whch could have caused spot splitting in the Rf/10 test, but significant in- hibition was only noted in tall fescue and Kobe lespedeza extracts in the 0.5-0.6 segments. No significant effects were noted in segment 0.6-0.7 which would have contained cinnamic acid. Table 3 Chromatographic characteristics of exuded compounds and matching standards.

Ferulic acid is a unit compound in the syn- thesis of lignin. It is one of the most commonly identified phenolic compounds leached or exuded from living plants, leached from plant lit- ter, or produced in the soil during decomposi- tion of lignin. It has been found in forest, grassland, peat, and cultivated soils by numerous researchers (1). Ferulic acid causes decreased protein synthesis (11, 12) and 54 Root Phenols in Kentucky Plants — Creek and Wade decreased root growth in lettuce (12), while in Paul’s Scarlet rose cells it causes increased syn- thesis of lipids and decreased synthesis of pro- tein and organic acids (13). In soybean leaves, ferulic acid reduces dry weight (14), chlorophyl a an b content (14, 15), depresses photosynthesis (15), and lowers stomatal conductance (15). Ferulic acid reduces Mg, Ca, K, P, Fe, Mn, and Mo uptake in Paul’s Scarlet rose cells (16), reduces K absorption by oak roots (17), and in- hibits phosphate uptake in three varieties of soy- beans (18). Ferulic acid acts like polyphenols in synergizing IAA-induced growth by counterac- ting IAA-decarboxylation (19). Ferulic acid in- creases total lipid content, changes fatty acid composition of and apparently degrades mem- brane function, and it decreases growth in vitro of Pisolithus tinctorius (Pers.) Coker and Couch, an ectomycorrhizal fungus considered very im- portant in the revegetation of mine spoils with pine and oak (Melhuish and Wade, unpublished data). Cinnamic acid, derived from L-phenyl- alanine (20), is known to be produced by many plants (1) and has been identified as a root secretion of guayule (21). Cinnamic acid has been found in corn field residues (22). It decreases rice growth (23), changes water rela- tions in beet cells (1), lowers stomatal conduc- tance and chlorophyl content, and decreases photosynthesis in soybean (15), and inhibits pro- tein synthesis and root growth in lettuce (12). Cinnamic acid causes a breakdown in protein synthesis from amino acids (15). Ferulic acid, in contrast, lowers protein synthesis by diversion of resources away from amino acid synthesis. Gallic acid is produced in plants from dehydroshikimic acid (20) and can be produced by digestion of hydrolyzable oak tannins (24). It is produced by several plant species and has been found in soils (1). Gallic acid inhibits growth of Amaranthus retroflexus L. and Bromus japonicus Thunberg. (25), and causes lower chlorophyl concentrations, decreased photosynthesis, and decreased stomatal resistance in soybean (15). It may influence the nitrogen cycle in ecosystems by inhibiting the nitrogen-fixing alga Anabaena in soils (26), nitrification by Nitrosomonas (27), and by reducing nodulization in legumes (28). Gentisic acid is produced by Celtis laevigata L. (29), and Eucalyptus globulus Labill. (30). Syringic acid has been found in crop residues and cropped soils (31, 32, 33, 34) and in the rhizosphere of Zea mays L. (35). It is pro- duced by yellow nutsedge (Cyperus esculentus L.) (36). The phenolic compounds produced by donor species in this study have a wide range of potential effects on other organisms and ecosystem functions. The actual importance of production of these phenolic compounds by the species we have examined will be determined by further study. Even if the amounts produced are low, they still may have significant synergistic effects. Additional phenolic compounds can result from decomposition of some of the ones found in this study; for example, vanillic acid is produced during the breakdown of ferulic acid and thus synergistic effects may be enhanced. Local concentrations associated with clays or organic matter in soils may enhance the importance of amounts produced (1).

NOTES Runt Egg In The Wood Duck.—Unusually small or runt eggs are extremely rare, with very few reports on the occurrence of such eggs in nature. Among the few species or groups in which runt eggs have been reported are the Canada Goose (Branta canadensis), gulls (Larus spp.), House Wren (Troglodytes aedon), Starling (Sturnus vulgaris), Common Grackle (Quiscalus quiscula), and several woodpeckers (Picidae) (Koenig, Wilson Bull. 92:169-176, 1980). In each of these, the incidence of runt eggs is extremely low, ranging from 0.02% in gulls to 0.6% in the Canada Goose. In one exceptional species, the Acorn Woodpecker (Melanerpes formicivorus), the percen- tage of runt eqgs was reported as 4.3% (Koenig 1980). On 4 May 1984 we found a runt egg in a Wood Duck (Aix sponsa) nest located in the Clay Wildlife Manage- ment Area, 16 Km ENE of Carlisle, Nicholas County, Kentucky. The nest also contained 11 normal eggs. The normal eggs subsequently hatched and the young had apparently all fledged by the time the nest was checked on 2 June. The runt egg measured 35.5 x 27.8 mm. Robinson (Condor 60:256-257, 1958) reported that the average size of 51 Wood Duck eggs was 46.8 x 37.4 mm; Bellrose (Ducks, Geese, and Swans of North America, Stackpole Books, Harrisburg, PA, 1976) noted that the average dimensions of a Wood Duck egg were 51.1 x 38.8 mm; and Palmer (Hand- book of North American Birds, Vol. 3, Yale Univ. Press, New Haven, CN, 1975) indicated that the average Wood Duck egg measured 50.7 x 39.0 mm. No mention of runt eggs was made by any of these authors. A review of the literature revealed no other published reports of runt eggs in the Wood Duck. The runt egg showed no evidence of embryonic development and contained no yolk. The absence of yolk was noted also in the runt eggs of other species (Romanoff and Romanoff, The Avian Egg, Wiley and Sons, New York, 1949). Little is known about runt eggs. Physiologically, the production of such eggs is apparently stimulated by temporary disturbances, ac- cidents, or infections in the oviduct (Romanoff and Romanoff 1949). Very few are thought to be the result of permanent abnormalities (Pearl and Curtis, J. Agricu. Res. 6:977-1042, 1916). The only species with a rather high incidence of runt eggs appears to be the Acorn Woodpecker. Koenig (1980) indicated that this may be due to the fact that these woodpeckers are communal nesters. As females attempt to maneuver within the nest cavities they may come in contact with each other or the walls of the cavity. Such physical contact may subsequently result in the production of runt eggs—GARY RITCHISON and KEITH D. KRANTZ, Department of Biological Sciences, Eastern Kentucky University, Richmond, KY 40475. The longnose dace, Rhinichthys cataractae (Valenciennes), in Kentucky.—On 4 April 1984, 3 specimens of the longnose dace, Rhinichthys catarac- tae, were collected from the Russell Fork of the Big Sandy River, Pike County, Kentucky at a site 1.21 KM (0.75 mile) downstream from the Kentucky-Virginia state line. These specimens represent the first known record for this species in the state. Other species col- lected at the same location included Campostoma anomalum, Etheostoma_ blennioides, Etheostoma caeruleum, Etheostoma variatum, and Percina maculata. The habitat from which these specimens were collected is similar to that described by Gilbert and Shute (in Lee et al., Atlas of North American Freshwater Fishes, p. 353, 1980). Russell Fork at this location is an Order VI mountain stream (elevation 311 m) with clear, fast-flowing, turbulent water and a substrate of boulders and rubble. The longnose dace is predominantly a northern species (Gilbert and Shute, loc. cit.) which ranges southward through the Appalachian Mountains into North Carolina, Tennessee, and northern Georgia. Burr (Brimleyana 3:53-84, 1980) considered the longnose dace as a problematic species in Kentucky and speculated that it possibly occurs in the Big San- dy or Upper Cumberland River drainages. This report confirms his assumption for the Big Sandy River drainage. Voucher specimens of Rhinichthys cataractae have been deposited at Southern Illinois University, Carbondale (SIUC), Eastern Kentucky University (EKU), and the Kentucky Department of Fish and Wildlife Resources at Frankfort (KDFWR). These specimens have the following measurements: (SIUC 10159) standard length (SL) = 43.0 mm, preorbital head length (PHL) = 5.0 mm, postorbital head length (POHL) = 5.0mm, and eye diameter (ED) = 2.5mm; (EKU 1305) SL = 50.0 mm, PHL = 5.5mm, POHL = 6.0 mm, and ED = 2.9mm; (KDFWR 1835) SL = 50.5 mm, PHL = 5.2mm, POHL = 6.0mm, and ED = 2.9 mm. The authors appreciated the field assistance of Messrs. Robert Bay and Doug Winford (U.S. Fish and Wildlife Service, Cookeville, Tennessee); the assistance of Mr. Ronald Cicerello (Kentucky Nature Preserves Commission) with the specimens; and Drs. Robert Kuehne (University of Kentucky) and Branley A. Branson (Eastern Kentucky University) for verify- ing our diagnosis. DOUGLAS E. STEPHENS and KERRY W.

Kentucky Academy of Science — 46(1-2) 57 Electrofishing vs. Angler Harvest: Dif- ferences in Length-Frequency Distribu- tions—lIn recent years, fishery managers have found it necessary to investigate new, more economical and innovative methods of sampling fish populations. Standard methods of netting and electrofishing are very expensive because of time involvement of person- nel and equipment. Use of angler-reported data have been shunned because of biases and inaccuracies. We have found that a combination of techniques can be the most inexpensive and accurate means fo obtaining data on certain fish populations. This method is the use of clerk-collected data from angler harvest. Several criteria should be met for use of angler- harvest data to be advantageous: (1) the species of in- terest should be a target species of anglers; (2) the species of interest should have few fishing regulations (i.e., bag or size limits); (3) fishing pressure and harvest need to be high during the collecting period; and (4) areas of fishermen concentration (e.g., fish- cleaning stations) are necessary to optimize data col- lection. During nesting and spawning in early May 1982, Kentucky Lake white crappie (Pomoxis annularis) data were collected by electrofishing and angler harvest. Fish taken by both methods were most fre- quently found in shallow water. Weather and water conditions did not change over the sampling period. When fishermen arrived at fish-cleaning stations, creels of cooperative anglers were borrowed for pro- cessing. Total length, weight, and sex were recorded for each fish and scale samples were taken. Fish were returned promptly to anglers for cleaning. The white crappie obtained by electrofishing were processed in the same manner. The length-frequencies of white crappie collected by electrofishing versus angler harvest were com- pared by a Smirnov Test (Conover, Practical non- parametric statistics, 2nd ed., Wiley and Sons, New York, N.Y., 1980). The dates and sample sizes of the length-frequencies were given for each day (Fig. 1). The differences in the comparison of the length- frequencies of the electrofishing day to each day of angler harvest, and to the 3-day combination angler harvest were significant. The range in size obtained by electrofishing. The angler data is skewed toward smaller fish, while the electrofishing data appeared more normal in distribution. Possibly these differences occurred because of the variability and biases associated with each method. There was a significant difference in the efficiency of the sampling methods. Fish obtained by angler harvest on 5/2/82 were processed at approximately 31 fish/hr.

(19, 20) and Henley (6) were used to compare the relative similarity of the Rolling Fork ichthyo- fauna with that found in those drainages. Three species reported by those researchers were ex- cluded from the analysis. Our reexamination of the specimens of Noturus eleutherus reported by Hoyt et al. (20) revealed them to be N. miurus. Voucher specimens for Fundulus olivaceus and Percina copelandi collected by Henley (6) are unavailable and we believe those species were misidentified. Thus, the total number of species for the Beech Fork and Salt River were con- sidered to be 65 and 70, respectively. Eighty two per cent of the Beech Fork fauna and 80% of the Salt River fauna are shared with that of the Rolling Fork. The close affinity of the faunas was not surprising considering their prox- imity to one another. Faunal differences were mainly a result of the absence of several large- river catostomids from our collections and the absence of the hiodontids, several cyprinids, an ictalurid, and a percid (e.g., Hiodon alosoides, H. tergisus, Hybopsis dissimilis, Notropis emiliae, Rhinichthys atratulus, Noturus stigmosus, Ammocrypta pellucida) from known the ichthyofauna of the Beech Fork and Salt River. The Rolling Fork appears to support the most diverse ichthyofauna within the Salt River drainage. The central part of the Rolling Fork drainage is of particular importance as it possesses habitat that supports 2 of Kentucky’s threatened fishes as well as several flourishing mussel beds. In view of recent efforts to develop the oil shale resources in the Rolling Fork drainage, special attention should be given to protecting and maintaining the integrity of these habitats and the diverse fauna they support.

Bryant Department of Biology, Thomas More College, Crestview Hills, Kentucky 41017 ABSTRACT The forest of the Lloyd Wildlife Preserve, Grant County, Kentucky was sampled and analyzed in 1978 and these results were compared to those Braun reported on this same forest in 1950. The same 16 tree species were reported in both samples, but the percentage composition of the canopy dominants varied considerably between the 2 sampling dates. This latter difference may be real or an artifact of difference in sampling techniques and size-class determinations. Resamplings of old-growth forests in the Midwest have shown that compositional changes do occur as a result of growth, death, and reproduction and can occur over time periods as short as 10 years. INTRODUCTON The canopy composition of the Lloyd Wildlife Preserve Forest (LWPF) in northern Grant County, Kentucky was reported by Braun (1). Because of the topography, and the forest’s location and species composition, she had dif- ficulty in deciding whether it was more represen- tative of the Outer Bluegrass or the Eden Shale Belt subregion of the Bluegrass Region. Her general concli sion was that it illustrates the type of mixed forest on the less steep slopes of the region along the boundary of the Outer Bluegrass and Eden Shale Belt. Braun’s description of the LWPF is as follows: “Here oaks (mostly white and black) form about 30 per cent of the canopy, beech 22 per cent, and sugar maple 15 per cent, in a mixed forest of 16 canopy species”. This forest was briefly described in “Naturalist’s Guide to the Americas” (2). Theiv description is as follows: “This [forest] consists of two tracts of about 20 acres each that have never been touched with the ax. It represents the natural woods as it existed originally in the Blue Grass region of Kentucky. The trees are mostly beech, maple, walnut, oak, tulip and other trees. Lying on the crest of the ridge they are not subject to wash and the soil is the accumulation of the humus of ages. Trees that blow over or fall down are not removed and the rotting logs are characteristic of a primeval forest”. At one time the 2 tracts that make up the LWPF were contiquous, but they are now separated by a field. Each old-growth tract is = 8 hectares in size. They are nearly identical in topography and soils. The most widely distributed soil in the preserve is the Lowell silt loam, a deep, well-drained soil formed in residuum from limestone and siltstone interbed- ded with thin layers of calcerous shale (3). Other soils present but of limited distribution in the forest are the Nicholson silt loam, a loessal soil 116 with a slowly permeable fragipan, and the Eden flaggy silty clay, a well-drained, but somewhat droughty soil (3). The average annual temperature for Grant County is 12.2°C, with an average January minimum of 6°C and a July maximum of 30°C (3). The average annual precipitation is 108.5 cm with approximately 55% of the total falling during April-September (3). This paper presents the results of a vegeta- tional study of LWPF and attempts to compare the results with Braun’s. It is recognized that ex- act comparisons are impossible due in part to Braun’s failure to give her canopy size class diameter determination. METHODS OF ANALYSIS The point-quarter method was used to sam- ple the forest (4). A total of 50 points was sampl- ed at 30-m intervals along line transects through the two forest tracts. No points were taken within 10 m of the forest edge. Only trees & 10 cm diameter-breast-height (dbh) were measured. Relative frequency (RF), relative density (RD), and relative dominance (RDo) were calculated, and these values were summed to give an im- portance value (IV) for each tree species. Tree seedlings and shrubs were sampled in 20 0.004 ha circular plots and saplings in 20 0.01 ha cir- cular plots. Seedling-sapling size classes follow Bryant (6) and are placed in 5 classes based on height and diameter. Following Abrell and Jackson (5), trees ® 30cm dbh were considered to be canopy trees and those smaller subcanopy trees. At Natural Bridge, Kentucky Braun (1) used © 30 cm dbh and at Ault Park, Ohio she used © 46 cm dbh as her canopy size. These were the only 2 forests based on her studies for which she gave canopy size determinations (1). Much of Dr. Braun’s correspondence and papers are held by the Cincinnati Museum of Natural History, but these have not been catalogued. No Trans. Kentucky Academy of Science — 46(3-4) 117 field notes are known to be in these papers so ex- act size for canopy members at the LWPF is not known, however, based on the 2 studies cited it is known that © 30 cm was a value that she used for canopy inclusion. Species diversity patterns were calculated from Braun’s (1) canopy data and for each stratum recognized in the present study using the Shannon-Wiener (7) index (H’): (H') = ->p,log’pi, where S is the number of species and p, is the proportion of each species in the forest. The similarity coefficient of Bray and Curtis (8) was used to calculate vegetational similarity between Braun’s sample and my sample for LWPF. It is C = (2w)/(a + b), where a = the sum of the canopy percentages for all tree species in Braun’s (1) sample, b = the sum for my sample, and w = the sum of the lower percentages for those species which are com- mon to the two samples. The z test was used to determine significance of difference between the two samples. Counts of fallen trees and standing dead trees were made at LWPF. Nomenclature follows Fernald (9) for all trees in the study. RESULTS If it is assumed that Carya cordiformis, Tilia americana, and Quercus rubra are the same as Carya sp., Tilia neglecta, and Quercus shumar- dii, respectively, of Braun’s (1) list, then the same 16 species were recorded in both samp- lings. Braun (1) counted canopy trees only. Thus, she gave no information on tree-size classes or on other strata. In my study there were 260 trees/hectare (t/ha), of which 46.5% (121 t/ha) were in the canopy and 53.5% (139 t/ha) in the subcanopy. A comparison of the present canopy to the one sampled by Braun (1) is presented in Table 1. Sugar maple is now the canopy dominant followed by white ash and then beech. It should be remembered that Braun (1) did not state her canopy class dbh so care was exercised in judg- ing the 2 samples. Of the 8 most prominent canopy trees in Braun’s study, Acer saccharum (sugar maple), Fraxinus americana (white ash) and Carya ovata (shagbark hickory) have higher percentage canopy composition in my sample; Fagus grandifolia (beech), Quercus alba (white oak), Q. velutina (black oak) and duglans nigra (black walnut) now have lower percentages and Tilia americana (basswood) is about the same. The other 8 tree species were of minor importance in both samples and it is their consistency which suggests that the canopy size class used in both samplings is approximately the same. Table 1.

No other tree species accounted for as much as 5% of the subcanopy, and the oaks and black walnut are not represented at all. Sugar maple ranks first in IV at 118.83 (Table 2) when all trees are included. The IVs for all other tree species generally follow the present canopy rankings. The total basal area for the forest is 35.5 m*/ha, with 86% of that con- tributed by the canopy component. Based on seedling-sapling data, only sugar maple reached tree replacement size and was represented in all 5 size classes (Table 3). Basswood is reproducing from sprouts and seed, but percentage seedling establishment of the oaks and hickories is low. Beech is not represented in the seedling-sapling stratum. The shrub layer is primarily composed of Asimina triloba and Lindera benzoin, and they are rather localized in the forest. Canopy diversity (H’) based on Braun’s data was 3.33; it is now 3.37. Subcanopy diversity, 1.22, is the lowest of any stratum. Total tree diversity is 2.53, seedling-sapling when grouped 2.32 and shrub 1.93. A total of 44 dead canopy trees was counted. Of these, 36 were windthrown, and 8 were standing dead. Most of them are oaks, beech, hickory, and basswood; however, some identifications were difficult due to many of the trees being in late stages of decomposition. 118 RH - Lloyd Wildlife Preserve Forest in Kentucky - Bryant Table 2.

In southern Iadiana Fagus-Quercus-Acer- Carya forests were termed “western mesophytic” (10) but, they were later renamed “mixedwoods” (11) which js similar to Braun’s (1) designation of the LWPF as “mixed forest”. The present canopy composition of 36.56% beech-maple and 31.19% oak-hickory may ap- pear at first to be little different from Braun (1). However, this is not the case, since individual tree species showed differences in canopy percentages. Similarity (C) between Braun’s (1) canopy and the present canopy is 70.4%. Bray and Curtis (8) reported that replicate samples in the same forests that they sampled probably would have C values of ~ 80-85%. Again, it is assumed that Braun and I were samplng ap- proximately the same canopy-size class for these differences to be meaningful. Recent studies of forests suggest that there may be shifts in the dominant tree species at long (12) or short term intervals (5, 13, 14). Lind- sey and Schmelz (13) and Schmelz et al. (14) recorded composition changes at Donaldson’s Woods, Indiana for 10 and 20 year periods, respectively. In their study of Hoot Woods, In- diana, Abrell and Jackson (5) noted composition changes due to growth, mortality, and reproduction over a 10-year period. These works and others (15, 16, 17, 18) point to an increasing importance of sugar maple and a decreasing im- portance of certain associated hardwoods in the Midwest. Buell et al. (19) stated that the upland oak forests of New Jersey were changing to maple. The abundance of sugar maple in the LWPF subcanopy shows its shade tolerance and thus its competitive advantage over associated species. Sugar maple benefits from release (20) and because of its dominance in the subcanopy is in position to take advantage of any canopy openings created by death or windthrow. White ash ranked second in IV to sugar maple largely because of its basal area. Schmelz et al. (14) found that white ash is increasing in importance in the canopy of Donaldson’s Woods, Indiana. Although white ash was quite abundant in the seedling classes at the LWFP its density was much lower in the sapling classes. This is in agreement with Fowells (21) who stated that white ash is shade tolerant when young, but with age it becomes intolerant. The lesser importance of beech and white oak in the LWPF canopy in 1978 than in 1950 (1) seems to be consistent with data reported in the literature. Abrell and Jackson (5) and Schmelz et al. (14) reported that beech is declining in the old-growth forests of Indiana. Their conclusions are based on resampling studies of greater preci- sion than used in this study. In Indiana, Schmelz et al. (14) found little growth or in- crease in density of oak in the seedling-sapling layers. Anderson and Adams (17) stated that in the forests of central Illinois, white oak was be- ing replaced by shade tolerant trees on mesic sites. Peet and Loucks (22) considered the oaks to be shade-intolerant species, and in their Trans. Kentucky Academy of Science — 46(3-4) 119 studies they found oak species to be of greatest importance in the larger size classes. This also is true for the oaks at the LWPF. Although sugar maple presently is the dominant tree species at LWPF, it seems premature to conclude that the forest is now a different type than at the time of Braun’s (1) sampling. Canopy diversity remains high, and no species have been eliminated from the LWPF between the 2 sampling periods. For the longer- lived species, i.e. oaks and beech, the potential seed source is still there to maintain diversity. The shifting and sorting of the dominants demontrates the dynamics of the forest system and seems consistent with the results of other resampling studies. The low diversity in the sub- canopy follows the trend hypothesized by Loucks (12). More work on the subcanopy is needed to determine its relationship to the canopy. The earlier reports on the LWPF (1, 2) con- sidered it to be climax. Its species composition (23) and basal area (24) are regarded as characteristics of the regional climax. Accor- ding to Horn (25), “The stability of the climax forest, if it exists, is not a stability of age struc- ture but a stability of species composition.” Thus, it would seem that the periodic resampl- ing of old-growth forests is one way to determine if they are stable.

RH - Mine Roof Falls in Kentucky — Smith Statistical Modeling and Mapping Selected Physical Characteristics Associated with Roof Falls in an Eastern Kentucky Coal Mine Alan D. Smith Department of Quantitative and Natural Science, Robert Morris College, Coraopolis, PA 15108 ABSTRACT Cost-sensitive mine planning systems assume that the physical and economic conditions that will have the greatest impact on cost and coal quality can be predicted accurately enough to assist mine planners in making decisions. Although roof falls are discrete in their occurrence, mapping applied to mining design assumes that the causes of failure are based primarily on geological and rock mechanical properties which may be con- tinuous in nature and, hence, be subject to detectable patterns. Two such factors, namely thickness of first im- mediate rock bed in mine roof and estimated volume of fallen material, both extremely important parameters in entry span calculations and design layout, were measured and mapped for 72 roof falls in an eastern Kentucky coal mine. The major statistical and analysis tools used in the present study were polynomial trend surface analyses, hypothesis testing and model comparisons of trend surfaces, and three-dimensional displays generated from commercially available computer software, via the incremental plotter. The mean thickness of the first immediate roof bed was determined to be 36 cm and the average volume of roof fall was found to be 294m‘. Traditional AVOVA techniques and hypothesis testing and model comparisons of trend surfaces delineated the fifth order surface (R? = 46%) as the statistically best fit (p = 0.01) over the lower-order, polynomial trends. However, no trend surface accounted for enough explained variance in predic- ting the estimated volume of fallen debris as a function of location in the mine site. In addition, three- dimensional graphical displays of structure contour, trend, and residual surfaces were generated to allow the potential user to portray selected distributions in order to plan preventative measures in the future. INTRODUCTION Since the first records were kept in 1838 on coal mine health and safety, more than 130,000 miners have lost their lives in mine accidents in the United States. Death rates in mines of this country have been found to be higher than in any other Western industrial nation engaged in coal mining (1). A major cause of this death and physical injury to underground coal mines is roof failure. As suggested by Moebs and Stateham (2), instability in coal mine roofs is considered to be either the result of defect- related/geological features or non-defect- related, such as the strength-stress state ex- isting in the rock mass (3). Support of underground entries are based on recommenda- tions of the physical characteristics of geologic structures and the overall effect the structures have on mine roof stability. The stability of coal mining tunnels, entries, rooms, and associated openings plays a major role in the success of any major underground project. Hence, if the main access openings to a new coal mine become deformed and damaged by strata movement to the extent of requiring serious repairs, special problems may arise which will have an influence on ventilation, im- pairment to speed and reliability of transport systems as well as the direct and indirect costs involved with the repair program (4-7). The mechanical design of a roof support system is basically a matter of a working knowledge of statics and dynamics, assuming that the imposed loads and mining conditions are known. However, in the Appalachian coal fields the general conditions are known well enough to allow for the majority of mining operations, including traditional room-and- pillar as well as longwall mining techniques, to be furnished with standard and commercially available supports. Of course, these support systems and roof control procedures are equip- ped with suitable variants and options (8). The overall design of a mining system, which design incorporates not only size and capacity of the equipment to be used; but includes: equipment adaptability to the mining scheme; equipment versus human constraint, operation at the de- signed levels; and coordination of operation, 122 RH - Mine Roof Falls in Kentucky - Smith maintenance and support design (8). Hence, a multitude of factors must be con- sidered in the successful underground operation (9). Cost-sensitive mine planning systems have been developed to help coal companies design underground mines that will recover coal reserves in the most profitable method. Informa- tion obtained from borehole logs, local mines, mining equipment manufacturers, and previous mining experience should be used in the mine planning process. According to Ellison and Scovazzo (10), cost-sensitive mine planning assumes that the physical and economic condi- tions that will have the greatest impact on cost and coal quality can be predicted accurately enough to assist mine planners in making deci- sions. In the planning process, many maps, such as coal seam thickness, expected roof cav- ing conditions, geologic lineaments, roof shale thickness, distance to the first sandstone, over- burden thickness, underclay thickness, as well as a host of other factors, can be generated as overlays on each other to assist planners in selecting appropriate locations and orientations for the portal, mains, submains, and longwall panels (3, 11-13). As compiled and summarized by Moebs and Stateham (11), a recent study to investigate in a graphic manner, all rock fall hazards related to geologic conditions in the Pittsburgh Coalbed for a 9-county area, located in northern West Virginia and Southwestern Pennsylvania, resulted in the systemic collection and analysis of field data. A total of 7 geologic and 5 mining-engineering related variables were found to be causally related to roof failure. However, only 3 of the significant geological parameters, namely overburden thickness, roof lithology, and vertical distance to the rider coal seam, were found to be useful in the final map preparation. The thrust of the present study is to ex- amine the spatial distributions of thickness of the first immediate roof bed and estimated volume of fallen debris from a historical record of previous mine roof falls in a particular site and determine if spatially predictive relationships ex- ist and plot them for future design work. Although mine roof falls are not random events and their occurrence is usually contibuted to an interaction of a host of geological and stress- strength parameters, frequently some of the conditions that cause failure may be continuous in nature. Example of this continuous nature in mine roof failure includes, as previously stated, overburden thickness, roof lithology, and ver- tical distances to selected bedding-plane features. Thickness of the first immediate roof bed may be continuous and a factor in ground control. In fact, this factor serves as a standard input variable in the calculation of safe entry spans in underground mine design. However, volume of fallen material in a roof failure is the result of a complex interaction of tensile and compression forces occurring in a_ rapidly changing geologic environment and conditions. The factors related to the amount of volume swell and material released from a fall are based on both continuous and discrete distributions. If these relationships exist, they may prove useful in a cost-sensitive mine plan to avoid selected in- teractions of ranges of thickness of immediate roof beds and possibly high volumes of fallen material for room or main entry development METHODS The major analysis and statistical tools used in the present study are polynomial-trend surface analyses (14), hypothesis testing and model comparisons of trend surfaces (15-18), and three-dimensional displays generated from commercially available computer software via the incremental plotter (19-21). One mine was selected for the study of the Eastern Kentucky coal fields to apply cost- sensitive mapping procedures with the com- bined use of trend surface analyses and three- dimensional modeling techniques. However, due to proprietary purposes, the mine site will remain unidentified. A total of 72 actual mine roof falls were measured and the thickness of the first immediate roof bed (in cm) and estimated volume of fallen rock (in m*) were recorded. The mean thickness was determined to be 36 cm and the average volume of roof fall was found to be 293 m°. Each roof fall location was recorded and trend surface analyses, via SYMAP (22) and a computer program sug- gested by Smith (15) were performed. In addi- tion, three-dimensional graphical displays were created. RESULTS Tables 1 through 2 illustrate the results of the model comparisons and hypothesis testing of polynomial trend surfaces in predicting thickness of immediate roof bed and volume of fall. Contained in Table 1 is the hypothesis testing results, in standard analysis (ANOVA) format, to determine if the fifth degree polynomial trend surface for thickness of im- mediate roof bed is significant. The variance ac- counted for by the fifth order surface was 46 per- cent, and this was found to be statistically significant (p = 0.01). Table 1 also contains a similar ANOVA table presenting the model Trans. Kentucky Academy of Science — 46(3-4) 123 comparison of the fifth order versus the fourth order trend surface for the thickness parameter. Table 2 presents a summary of the actual, predicted, and residual or error values of the im- mediate mine bed. The fifth-degree regression equation, as shown at the bottom of the table, was employed to derive the predicted values for immediate roof bed. In Table 1 is a summary of the F-ratios, probability levels, R* for both the full and restricted models, degrees of freedom- numerator, degrees of freedom-denominator, and significance for each trend surface for the associated roof fall parameters. As evident from the table, the fifth degree polynomial trend sur- face was the statistically best fit; however, no trend surface accounted for enough explained variance in predicting the estimated volume of fallen debris as a function of location in the mine site.

Figures 1 and 2 illustrate the basic isopach con- tour for thickness of first immediate roof bed, Figure 3 displays the fifth degree polynomial surface, and figures 4 and 5 present the three- dimensional distribution of residuals (the dif- ference between the actual and predicted values). Figures 6 through 11 display similar in- formation for estimated volume of fall debris from the mine roof, using fourth-order surface as an example. Since, several statistical tech- niques were applied to the response surfaces found in the figures, a common orientation was not shared among all the graphical displays. The perspective were changed from NE to SE in order to view high and low areas on the struc- ture, trend, and residual maps to aid in their overall interpretation and illustrate the plotting software’s versatility in graphically presenting the distributions. DISCUSSION As evident from Figures 1 through 11, and Tables 1 and 2, a significant and predictive trend exists for thickness of the thinnest immediate layer in the mine roof, but not for estimated volume of fallen debris, for the roof falls studied. A fourth-degree polynomial surface accounted for a significant amount of explained variance (R* = 0.46) in predicting thickness of immediate roof beds. However, as shown in figures 4 and 5, residuals or the errors between the actual and predicted values occur and are centrally located. Although coal-mine failure areas are discrete in their actual occurrence, mapping procedures applied to mine-layout design assumes that the causes of failure are primarily based on geological and rock mechanical pro- perties, which may be continuous in nature and, hence, be subject to detectable patterns. As evi- dent from the statistical analyses of response Trans. Kentucky Academy of Science — 46(3-4) 125 Figure 1.

Three-dimensional Model of the Fifth-Order, Polynomial Trend Surface for Thickness of First Immediate Roof Layer in Mine Roof as Viewed from the Northeast Direction. surfaces, detectable patterns of the thickness of the first immediate roof bed, associated with the recorded roof falls, were found. This pattern is probably due to continuous geologic conditions found in the mine site. However, no detectable pattern was discovered for determining the regional trend of estimated volume of fallen rock in these failure areas throughout the mine site. Although the size of roof falls are related to mine span, bedding and geological features that may be continuous, a host of other factors and their sequential interactions were evidently too com- plex to effective map and predict, without con- trolling for these other important parameters. In addition, since volumes of roof falls are general- ly not continuous in space, it may not be ap- parent that polynomial modeling is appropriate in this circumstance. However, the search in the literature of coal-mine roof failure presented no other acceptable alternative for mapping and predictive evaluation of size and volume characteristics of fallen debris as a function of spatial coordinates. The figures show the magnitude and distribution of error in prediction of the various roof-fall parameters. However, as demonstrated in Table 2, the spatial coordinates of the Figure 2. Structure Contour of Thickness of First Immediate Roof Layer in Mine Roof as Viewed from the Northeast Direc- tlon, Figure 4, Three-dimenstonal Model of the Fifth-Order, Polynomial Residual Surface (Positive Values) for Thickness of First Immediate Roof Layer in Mine Roof as Viewed from the Southeast Direction. measured values are somewhat clustered and irregularly-spaced throughout the mine layout. When fitting a continuous polynomial surface over this type of data, the few control points along the periphery of the mine site allows the surface to be distorted and highly exaggerated. The magnitudes of the parameters, as evident from the legends on each figure that is derived from the curve-fitting of the regression equation were quite large and unrealistic. For example, in Figures 1 and 2, the actual data range, starting from the base plane, was 0.0 to 2.16 meters. The magnitudes for immediate roof-bed thickness reached an unrealistic value of over 10,871 meters. These extreme values, of course, are the extrapolations of the polynomial surface beyond the constraints of the data, where spatial control is not achieved. Hence, most of the graphical displays are merely artifacts or abstracts of the polynomial surface that has no real meaning. Although, the equations used to predict im- mediate roof-bed thickness are restricted to about two-thirds of the mine layout, the methodology is essentially correct. However, a greater attempt must be made to have represen- tative control points through the study area. One useful function of generating these plots are 126 RH - Mine Roof Falls in Kentucky - Smith to isolate these areas that are unconstrained in _ tions of the polynomial model. In this way, the terms of modeling.

CONCLUSIONS The major benefit of modeling research is to be able to visualize the actual distributions of important parameters associated with roof falls. Examples illustrated in this research allow the user to portray selected distributions of parameters in order to access the potential of these techniques as an aid to avoid potentially problematic areas. The use of plotting statistical as well as actual contour surfaces, allows the in- vestigator a chance to actually visualize what the surface looks like and the residuals or errors in prediction and their magnitudes. This process can bring in the administrator and engineer’s “common sense” as well as geological and engineering judgement into play to determine the best fit or model, if one exists. With the in- creasing use and availability of appropriate soft- ware and hardware, computer modeling should be used in conjunction with statistical models in estimating the usefulness and limitations of trend-surface analyses for predictive purposes in the mining industry. 128 RH - Mine Roof Falls in Kentucky - Smith LITERATURE CITED .

RH - Effect of Soil Phenols on Kentucky Pisolithus — Melhuish and Wade Effect of Soil Phenolic Compounds on Growth and Fatty Acid Composition of Pisolithus tinctorius J. H. Melhuish, Jr. and G.L. Wade United States Department of Agriculture, Forest Service Northeastern Forest Experiment Station, Berea, KY, USA 40403 ABSTRACT One to 1000 » mol/L of ferulic, p-coumaric, and vanillic acids in liquid growth media decreased growth (dry-weight production), increased total lipids as percent of dry weight and lowered the 18:1 to 18:2 fatty acid ratio in the ectomycorrhizal fungus Pisolithus tinctorius. Vanillic acid affected the fatty acid ratios only at the higher concentrations tested. Two-and three-times normal nutrient concentrations decreased growth but partly offset some of the effects of ferulic acid. These results suggest that phenolic compounds produced by some higher plants may cause alteration of growth and liquid synthesis in P. tinctorius. INTRODUCTION Reclamation of surface-mined lands for forestry and wildlife uses is an established and desirable practice, but it has declined in the United States in recent years due to frequent failure of reforestation efforts. The Surface Min- ing Control and Reclamation Act (Public Law 95-87) and regulations promulgated under it now require regrading of spoils and establishment of a nearly complete herbaceous ground cover. Competition between this herbaceous vegeta- tion and tree seedlings often results in death of trees. One of the mechanisms of this competi- tion may be allelopathy, the chemical in-- terferences of plant species with each other (1). Allelochemics may be acting directly to inhibit the survival and growth of planted trees, retard the development of fungi that form mycorrhizae, and/or interfere with the process of mycorrhizal formation. Water extracts from prairie soils inhibited oxygen uptake of Monterey pine (Pinus radiata D. Don) mycorrhizae to a greater extent than did water extracts of forest soils (2). Grass-root decomposition products also reduced mycor- rhizal infection of Monterey pine (3). Many workers have found that mycorrhizare are es- sential for establishment of trees in adverse en- vironments such as mine spoils (4). Plant- produced compounds are known to _ inhibit mycorrhizal associations (5, 6, 7, 8). Phenolic compounds limit ion uptake through alteration of membrane properties, and it has been sug- gested that phenolic acids can depolarize mem- branes (9, 10). Little work has been done on the influences of specific allelochemics on mycor- rhizae (11). Ferulic, p-coumaric, and vanillic acids are phenolic acids that have been identified in other allelopathic situations (12, 13, 14, 15), and all 3 129 of these compounds have been found in soils (8, 15, 16, 17). Ferulic acid is known to be exuded by root systems of Festuca arundinacea Schreb., Eragrostis curvula (Schrad.) Nees, and Lespedeza striata Thunb., which are commonly used as ground cover in surface mine reclama- tion (18). Vanillic acid is a product of fungal degradation of ferulic acid (19). This study investigated the effect of ferulic acid (3-(4-hydroxy-3-methoxypheny]l)-2-propen- oic acid), p-coumaric acid (3-(4-hydroxypheny])- 2-propenoic acid), and vanillic acid (4-hydroxy-3 -methoxybenzoic acid) on the growth and lipid content of the ectomycorrhizal fungus Pisolithus tinctorius (Pers.) Coker and Couch, a pioneering ectomycorrhizal fungus associated with pine on sparsely-vegetated dark-colored acid surface mine spoils (20). MATERIALS AND METHODS Mycelia of P. tinctorius were transferred to petri dishes containing approximately 25 ml of glucose-ammonium tartrate agar medium (5). When the diameter of the colonies was approx- imately 50 mm., 25 mm? sections were cut on the perimeter of mycelial mats and transferred to petri dishes containing fresh agar medium. After 3 days, individual sections that had developed aerial hyphae were transferred into forty, 125-ml Erlenmeyer flasks containing 50 ml of glucose- ammonium tartrate medium without agar (21). The phenolic compounds were sterilized by filtration and added to the sterile nutrient solu- tion. Flasks were incubated at 25°C in the dark for 21 days. The mycelia from each treatment group of 40 flasks were recovered by filtration using a Buchner funnel, pooled, freeze-dried, macerated in a Waring blender, and funneled in- to an extraction thimble. The remaining liquid 130 RH - Effect of Soil Phenolic on Kentucky Pisolithes - Melhuish and Wade. media were pooled by treatment. After acidifica- tion, phenols were extracted from about 80 ml of each medium and separated by thin-layer chromatography (TLC) (22). Ultraviolet-visible scans of the liquid media (reduced 1:10) were performed on a Varian SuperScan 3 spec- trophotometer for the purpose of determining absorbance peaks and thus relative amount of metobolites released into the media. Macerated mycelia were weighed and lipids were extracted in chloroform-methanol accor- ding to Melhuish and Hacskaylo (23), and dried at 40°C under nitrogen. The lipid extract, redissolved in chloroform, dried, and weighed, was considered to be the total lipid fraction. Fat- ty acids were separated from the total lipid frac- tion after saponification with alcoholic KOH, methylation, and fractionation on an alumina column. They were stored under nitrogen in a freezer for later use. The fatty acid methyl esters were separated by gas-liquid chromatography (GLC). The separated methyl esters were characterized by comparing their retention times to those of standards. A methyl stearate standard was used for quantitative analysis. An experiment was conducted using 1, 2, or 3 times (1X, 2X, 3X) the normal, concentration of nutrients in media with and without 100 pmol/L ferulic acid to determine whether the phenolic compounds complexed nutrients in the media. The flasks were inoculated, incubated, pooled, and processed in the same manner as described in the preceding experiments. RESULTS »/ Dry weight production and final pH of the media have a significant (a = .001) negative correlation (- 0.84) (Table 1). Initial pH of the media was 5.40, and the pH dropped propor- tionally to growth of the fungus. Additionally, the mycelial mats were lighter in color, and the sizes of the fungal mats were smaller at the higher concentrations of phenolics. At 1000 umol/L, and occasionally at 100 umol/L, dark- colored droplets appeared on the tops of the mycelial mats. The media also became darker with each increase in concentration of the phenolic compounds. UV-visible scans (Fig. 1) of the autoclaved media before inoculation with the fungus showed no absorption in the visible range, but there was a low peak (optical density = 0.064) at about 260 nm. A peak at the same frequency was present in all subsequent scans of the treated media. The optical density of the vanillic acid treatment increased from .301 in the control to .622 at 1 mol/L, but optical densi- ty was lower at 10 and 100 umol/L (.503 and .383, respectively). Optical density was 0.650, and a second peak appeared at 285 nm in the 1000 pmol/L treatment. Table 1. Influence of common phenolic compounds on dry weight production in Pisolithus tinctorius.

UV-visible scan of liquid media containing different concentrations of vanillic acid at end of ex- periment. NI = No inoculated; C = control; 1, 10, 100, 1000 are in pmol/L. Extraction of the vanillic acid treatment media and separation by TLC indicated that compounds secreated by the fungus included phenolic compounds. The TLC chromatrogram at 1000 umol/1 vanillic acid showed numerous, intense, overlapping bands not seen at lower concentrations. Percent total lipid in P. tinctorius increased when p-coumaric and vanillic acids were added to the media, but ferulic acid did not consistently show this response (Table 2). With the smallest additions of ferulic and p-coumaric acids, there was a change in the ratio of 18:1 to 18:2 fatty acids; the proportion of 18:1 decreased to about half of the control value (Table 3). Increasing nutrient content of the media to 2X or 3X the normal concentration resulted in decreased dry-weight production of the fungus and a corresponding higher final pH of the media (Table 4). Adding 100 pmol /I ferulic acid to the 1X media reduced dry-weight production by 62%, but the proportional reduction in dry weight and final media pH were less at 2X and 3X the normal nutrient concentration. Optical density of the media increased with increased nutrient concentrations, with and without ferulic acid. Ferulic acid also caused optical density to increase at normal nutrient concentrations. DISCUSSION The negative correlation of dry weights of P. tinctorius and concentrations of phenolic acids in the media indicate that the phenolic acids are detrimental to P. tinctorius growth. Concentra- tion of phenolics and the appearance of dark droplets on the mycelial mat surface at the highest concentrations of phenolics suggest (1) production of compounds in response to the phenolics or (2) phenolic-caused leakage of fungal metabolites into the media. The apparent higher potency of ferulic and p-coumaric acids (cinnamic acid derivatives) over vanillic acid (benzoic acid derivative) parallels Glass’ (9) observation that cinnamic acid derivatives are more potent inhibitors of phosphate uptake than the corresponding ben- zoic acid derivatives. In the vanillic acid experi- ment, the control 18:1 to 18:2 fatty acid ratio was lower than the control of the p-coumaric and ferulic acid treatments. This may be at- tributable to temperature fluctuation problems in the growth chamber used in the vanillic acid and nutrient concentration experiments. Lower temperatures themselves also result in a lower ratio of 18:1 to 18:2 fatty acid (Melhuish, un- published data). UV-visible scans of the liquid media at the end of the vanillic acid experiment suggest that even the smallest amount of vanillic acid caused significant release of additional metabolites into the media (260 nm peak). Lesser amounts of re- leased compounds at 10 and 100 umol/L may be due to reduced or altered physiological func- tions reponsible for production or release of the media metabolites. At 1000 umol/| the fungus metabolism may have changed radically, resulting in more materials contributing to the 260 nm peak and causing the additional 290 nm peak. Alternatively, membrane integrity may have broken down, allowing more metabolites to be released — including some that were re- tained by membranes at lower toxin concentra- tions. Increasing nutrient concentraton decreased dry-weight production in the absence of ferulic acid, indicating that oversupply of nutrients was toxic. Addition of 100 umol/L of ferulic acid to the normal media level of nutrients reduced dry- weight production by 62%, but addition of 2 or 3X normal nutrients to 100 pmol/L ferulic acid in media did not result in additional growth sup- pression. Optical densities (which we believe to be a measure of excretion or “leakage”) in- creased more due to the addition of nutrients than to addition of ferulic acid. The influence of ferulic acid was appreciable only at 1X untrient concentration. Decoloration of the mycelium accompanied by the appearance of dark-colored droplets at the highest toxin concentrations in the other experiments was observed only in the 1X nutrient concentration with ferulic acid. This supports the idea that additional nutrients, though in themselves toxic, somewhat ameliorate the effects of the toxin. Many have observed P. tinctorius sporocarps in the harsh envionments of surface mines which were bare of vegetation except for scattered host trees (Beckjord, personal com- munication). We have not found P. tinctorius sporocarps on surface-mined sites that have 132 RH - Effect of Soil Phenolic on Kentucky Pisolithes - Melhuish and Wade. progressed beyond the initial stages of succes- sion or on mined lands reclaimed with extensive grass-forb covers. We suspect that plant- produced compounds might be inhibiting P. tinctorius in such situations. In a field with woody ground cover, growth of Quercus rubra L. seedlings infected with P. tinctorius was significantly inferior to that of seedlings with Scleroderma auranteum Pers. (24). Molina (25) noted that some phenolics secreted by one higher plant might inhibit mycorrhizae forma- tion between another higher plant and a compatible fungus by inhibiting cellulose production. Changes in P. tinctorius 18:1 to 18:2 fatty acid ratios, which may be a reaction to stress, can also be induced by decreasing C:N ratios (23), changing the nitrogen source for ammonia to nitrate (26), and lowering environmental temperature (Melhuish, unpublished). P. tinc- torius is, in general, more susceptable to toxic effects of cadmium, lead, and nickel than are other mycorrhizal fungi (27). Since mycorrhizae are necessary for tree growth in severe en- vironments, other mycorrhizal fungal genera such as Russula, Suillus, Lactarius, Amanita, and Boletus that have been found in forests next to surface mines might be more suitable sym- bionts for plantings on vegetated surface-mined lands.

Jones Department of Biological Sciences, Eastern Kentucky University, Richmond, KY 40475 ABSTRACT Documented county distributions are given for 5 species, each the sole representative of its family in Kentucky. The number of county records based on a herbarium survey, are as follows: 19 for Pachysandra pro- cumbens (Buxaceae); 13 for Clethra acuminata (Clethraceae); 2 for Comptonia peregrina (Myricaceae); 12 for Bumelia lycioides (Sapotaceae); and 5 for Stewartia ovata (Theaceae). An account is given of the distribution, habitat, and associates of each species. INTRODUCTION This paper reports the Kentucky county distributions of the Buxaceae, Clethraceae, Myricaceae, Sapotaceae, and Theaceae, each represented in the state by a single species. This study was initiated as part of an organized effort by Kentucky botanists to document the distribu- tions of vascular plants in the state, to eventual- ly lead to the production of a flora of Kentucky. METHODS AND MATERIALS The county maps presented here are based on herbarium specimens examined during this study only, a total of 170 specimens from 19 her- baria. Literature reports that I could not docu- ment and records for cultivated plants are ex- cluded. Identifications were carefully checked and the pertinent label data were recorded. The family classifications follow those of Cronquist (1), while the species treatments are based on Little (2, 3), except where noted. RESULTS County distributions of 5 species in Ken- tucky are presented in Figure 1. Pachysandra procumbens is reported from 19 counties, Clethra acuminata from 13, Comptonia peregrina from 2, Bumelia lycioides from 12, and Stewartia ovata from 5. According to Richard Hannan (pers. comm.), the Kentucky Nature Preserves Commission has recent collec- tions from the following additional counties: Pachysandra procumbens—Lincoln; Clethra acuminata—Rowan; Bumelia lycioides—Butler, Grayson and McLean. These collections are not yet accessioned and available for study. For the 5 familes under consideration, | found no evidence of any other species occurring natively in Kentucky. Pachysandra terminalis Sleb. and Zucc., the Japanese pachyandra, may sometimes persist around old homesites. Clethra alnifolia L. was reported for the state by Defriese (4), and listed without comment by Garman (5), but I was unable to locate any specimens. Bumelia lanuginosa (Michx.) Pres. occurs in Illinois and Missouri counties adjacent to Kentucky, and could eventually be discovered in western Kentucky. Garman (5) noted an old report of Stewartia malachodendron L. in Ken- tucky, but he was “disposed to question the ac- curacy of the reference.” DISCUSSION 1. Buxaceae—Pachysandra procumbens Michx. Allegheny spurge. The Buxaceae is a mostly evergreen, woody family of worldwide distribution, and is classified in the subclass Rosidae, order Euphorbiales. There are 5 genera with about 60 species. The genus Pachysandra contains 4 species, with P. procumbens being the only native American species (6). Pachysandra procumbens occurs in the southeastern United States only, from central Kentucky to Georgia and Louisiana. Braun (7) mapped the southeastern distribution of the species, and later (8) listed 8 conties in south- central Kentucky. In 1950 Braun called the Allegheny spurge one of the abundant and characteristic species of the Western Mesophytic Forest Region (9). Robbins (6) gave 8 Kentucky counties for the species, and describ- ed the habitat as “calcareous, clayey soils, on ravine slopes, in deciduous woods...” All of the 28 counties reported here (Fig. 1) are in south-central Kentucky, from Fayette to McCreary and Simpson Counties. The Fayette Couniy record is from Raven Run, evidently the most northerly known site for the species. 134 Trans. Kentucky Academy of Science — 46(3-4) 135 Pachysandra procumbens is a low-growing, rhizomatous, slightly woody plant of the her- baceous layer in mesic woods. It has crowded, evergreen coarsely-toothed leaves, and small spikes with apical male and basal female flowers. The Allegheny spurge flowers in early southeastern United States has been published by Thomas (10). Clethra acuminata is an Appalachian species occurring from West Virginia through Kentucky to Georgia. Garman (5) cited only Wolfe County for the species, and MclInteer (11) (SQOS sere PW ELR 6) ate US Y (Sa AAT Tes et} SE ) fet NS RIS LES S, Figure 1. Kentucky county distribtuions of Pachysandra procumbens (A), Clethra acuminata (B), Comptonia peregrina (C), Bumella lycioides (D), and Stewartia ovata (E). spring, but the brownish spikes are often obscured by leaf litter and are easily overlooked. I have observed this species in McCreary County growing in rich woods with Hydrastis canaden- sis, Anemone quinquefolia, Panax trifolium, Trillium luteum, and Trillium sulcatum. 2. Clethraceae—Clethra acuminata Michx. Sweet pepperbush. The Clethraceae is a woody family with a single genus, Clethra, and about 65 species distributed in the Americas and in Asia. The family is classified in the subclass Dilleniidae, order Ericales. Clethra has long been con- sidered as closely allied with the Ericaceae, and in some older treatments it is listed under this related family. A study of the family in the considered the sweet pepperbush as very rare in black shale regions and scarce in the eastern coal fields. Braun provided a distribution map of the species (7) and in 1943 she listed 11 counties, giving the habitat as “steep mesophytic sandy banks, shaded sandstone cliffs and gorges” (8). Wharton (12), in her study of the black shale areas, also called the plant rare, and reported it from Powell County only. In Little (3), the species is mapped through about 8 counties in northeastern Kentucky and 7 counties in southeastern Kentucky, with an outlying record from Bullitt County. The 13 counties reported here (Fig. 1) range from Pike to McCreary and Pulaski counties. The sweet pepperbush is probably much more RH - Plant Distribution in Kentucky - Jones 136 widespread, but many of the eastern Kentucky counties have been very poorly collected. The species can be easily identified by the reddish, shreddy bark, silvery buds, and the terminal racemes of white, 5-merous flowers, which develop into small globose capsules. It is less than 6 m tall, and occurs in the understory of mixed mesophytic communities typically dominated by Liriodendron tulipifera, Betula lenta, Tsuga canadensis, and Fagus grandifolia, with understory associates such as Magnolia macrophylla, Cornus florida, and Stewartia ovata (13). 3. Myricacae—Comptonia peregrina (L.) Coult. Sweet fern. The Myricaceae, of the subclass Hamamelidaceae, order Myricales, is a woody family of 3 genera and about 50 species, distributed in both the Old and New World. Most of the species are in the genus Myrica, which is represented in the southeastern United States by 4 species (14). Comptonia is a monotypic genus native to eastern North America. Comptonia peregrina, also called Myrica asplenifolia L. in some manuals, occurs from Canada to Georgia and is one of Kentucky's rarest woody plants. It was first reported for Kentucky by Braun (8), who collected a specimen (McCreary Co.; Braun 1010, GH!) at the “S. fork of Cumberland River river bank,” on June 18, 1935. Braun noted on the label that the locality was the “southernmost interior record.” The species was relocated in 1978 (15) on gravel bars in Big South Fork of Cumberland River, McCreary County (Wofford 78-96, EKY!, NY!). In 1980 a single plant was found on the east bank of the Rockcastle River, Laurel County (Jacobs 0616791, EKY!). The sweet fern is thus known from only 2 counties in Kentucky (Fig. 1). I searched the Laurel County site in April, 1984, without suc- cess. According to Max Medley (pers. comm.), a good number of individuals have now been located at the McCreary County site. This plant is a many-branched, aromatic shrub, about 1.5 m tall, with pinnately-lobed leaves, flowers in aments, and nutlets in a bur-like cluster. It grows on rocky gravel bars and stream banks that are subjected to frequent scouring. These are unique Kentucky communities, containing many other unusual species, such as Orontium aquaticum, Calycanthus floridus, and Con- radina verticillata (16). Comptonia peregrina is a rare plant study element of the Kentucky Nature Preserves Commission (16), and is listed as a threatened species by Branson et al. (17). 4. Sapotaceae—Bumelia lycioides (L.) Pers. Southern buckthorn. The Sapotaceae are members of the subclass Dilleniidae, order Ebenales. The family includes about 70 genera and 800 species, most- ly of tropical. regions. In the genus Bumelia there are about 25 species, with 6 occurring in the southeastern United States (18). The southern buckthorn is distributed through the southern states from Kentucky to Virginia, Florida, and Texas. Garman (5) noted only 2 counties, and MclInteer (11) stated that the species is very rare in the sandy, acidic soils around the western coal fields. McInteer map- ped the species in Kentucky, finding it fairly common in Edmonson and Monroe counties (19). Braun (8) gave the habitat of the species as “shaded limestone cliffs,” and cited 5 counties. Little (3) mapped the species through 9 counties of west-central Kentucky. The present study documents 12 counties for the species (Fig. 1), ranging from Ballard to Wayne County. The southern buckthorn is nondescript and is probably often overlooked. It is a small thorny tree with alternate, entire leaves, small flowers in axillary clusters, and the fruit is a berry. It may occur in both upland limestone areas and in bottomlands, often in open habitats. In the uplands, Bumelia lycioides is associated with Rhamnus caroliniana, Rhus aromatica, and Juniperus virginiana, while in wetter soils it grows with Asimina triloba, Lindera benzoin, and Sambucus canadensis (20). 5. Theaceae—Stewartia ovata (Ca.) Weatherby. Mountain Stewartia. The Theaceae are classified in the subclass Dilleniidae, order Theales, and includes about 40 genera and 600 species. According to Wood (21) there are 6 species in the genus Stewartia, with 2 native to the southeastern United States. The family also includes Gordonia lasianthus (L.) Ellis, a coastal plain species, and Franklinia alatamaha Marshall, discovered by John and William Bartram in 1765 in McIntosh County, Georgia. The famed “Lost Franklinia” has not been seen in the wild since 1790, but persists through cultivation. Stewartia ovata, the mountain stewartia, ranges through the southern Appalachians from southeastern Kentucky to central Alabama. Garman (5) named four counties— Bell, Letcher, Powell, and Rowan for the species. McInteer (11) treated the plant as a rather common species of the eastern coal fields, and later (19) gave a four-county dot map of the species in Kentucky. Braun (8) listed Bell, McCreary, and Whitley Counties, and described the habitat as “meophytic ravines and gorges, and occasional- ly on ridges.” The mountain stewartia is mapped by Little (3) in 4 counties of southeastern Ken- Trans. Kentucky Academy of Science — 46(3-4) 137 tucky, with an additional site from Menifee County. I found records of Stewartia ovata from Bell, Laurel, McCreary, Pulaski, and Whitley Counties (Fig. 1). Most of the collections were from the Yahoo Falls and Cumberland Falls regions. Except when flowering, the mountain stewartia can be easily overlooked. It has sim- ple, alternate leaves, with distinctive spinulose margins, single bundle traces, and pubescent buds. The flowers, however, are remarkable; they are up to ten cm across, with large, white imbricate petals, numerous stamens with purplish filaments, and a 5-styled ovary. The fruit is a loculicidal capsule, about 1.5 cm in diameter. Stewartia ovata often grows with Clethra acuminata, and has similar associates.

RH - Predatory Behavior in Kentucky Kestrels — Kellner and Ritchison An Examination of the Predatory Behavior of Captive American Kestrels Christopher J. Kellner’ and Gary Ritchison Department of Biological Sciences Eastern Kentucky University Richmond, KY 40475 ABSTRACT The predatory behavior of captive American Kestrels (Falco sparverius) was examined to determine if kestrels attacked or handled vertebrate and invertebrate prey in different ways. A total of 157 attacks on 92 vertebrate and 65 invertebrate prey items was observed. A comparison of the attacks on vertebrates versus in- vertebrates revealed several significant differences. (1) Powered (flapping) flights generally were used in attacks on vertebrates while attacks on invertebrates were evenly divided between powered flights and gliding flights. (2) Kestrels made direct contact with invertebrate prey more frequently than with vertebrate prey. However, when only live, adult vertebrates were considered, kestrels made direct contact with vertebrate prey more frequently than with invertebrate prey. (3) Whereas all vertebrate prey were taken to a perch before being consumed, most invertebrate prey were consumed on the floor of the aviary. (4) Kestrels cached significantly more vertebrates than invertebrates. Thus, kestrels utilized different types of attacks on vertebrates and invertebrates and handl- ed these two types of prey differently after successful attacks. Such differences probably relate to differences in the abilities of vertebrates and invertebrates to detect and elude a predator and differences in the average size of vertebrate and invertebrate prey. The behavioral differences exhibited by American Kestrels appear to (1) in- crease the chances of successful attacks, (2) increase the chances of further successful attacks within an area, (3) reduce the chances that prey will escape once captured, and (4) both increase the time available for hunting and reduce the energy expended while hunting. INTRODUCTION The American Kestrel (Falco sparverius) is an opportunistic predator that feeds on a wide variety of both vertebrates and invertebrates (1, 2, 3). Certain aspects of the predatory behavior of kestrels have been examined. For example, attempts have been made to determine the im- portance of such factors as shape, color, and movement in the selection of prey by kestrels (4, 5, 6, 7). Other investigators have reported field observations suggesting that kestrels may use different types of attacks for different types of prey (8, 9). The objective of this study was to ex- amine the predatory behavior of captive American Kestrels. Specifically, the objectives were to determine if kestrels (1) utilize different types of attacks on vertebrate and invertebrate prey and (2) handle vertebrate and invertebrate prey differently after a successful attack. METHODS Feeding trials were conducted with 3 American Kestrels (2 females, 1 male) in a 6x 6 x 3 m outdoor aviary. These kestrels were cap- tured near Richmond, Madison Co., Kentucky, using a bal-chatri trap (10). Trials were con- ducted from 5 May to 21 September in 1983 and from 24 May to 28 May in 1984. Observations were made through a one-way mirror from an observation booth located adjacent to the aviary. The side of the aviary next to the obser- vation booth was covered so observers could enter and exit the booth without being observed by the kestrels. A tube 70 cm long with a diameter of 10 cm allowed observers to place prey items into the aviary while seated in the observation booth. Both vertebrate and in- vertebrate prey were offered in this manner. Vertebrate prey included both adult and young (less than a week old) laboratory mice (Mus musculus) and adult House Sparrows (Passer domesticus). Invertebrate prey included a cray- fish (Cambarus sp.), cicadas (Tibican sp.), grasshoppers (Acrididae), crickets (Gryllidae), and cockroaches (Periplanta americana). Several dead mice (adults) and 2 dead rats (Rat- tus norvegicus) were also offered as prey to the kestrels. Prey items were classified as either large (average weight= 25 gms or more) or small (average weight = 10 gms or less). Large 1 Department of Zoology, University of Arkansas, Fayetteville, AR 72701 Trans. Kentucky Academy of Science — 46(3-4) 139 items included adult mice, young rats, and House Sparrows. Small items included young mice and all invertebrates. The average weights are listed in Table 1. Table 1. Average weights of prey items offered to kestrels. Item No. Offered Avg. wat.

The time interval between presentation of prey and the in- itiation of an attack by a kestrel was measured with a digital stopwatch. Other information noted with each attack included: (1) whether a prey item was contacted immediately or if the kestrel landed next to the item prior to contact, (2) whether a prey item was cached or was con- sumed immediately, and (3) if an item was car- ried to a perch, whether it was carried in the talons or the bill. RESULTS A total of 176 prey items was offered to kestrels. Nine of these potential prey items escaped and 10 were ignored; thus, a total of 157 attacks were observed (Table 2). Both vertebrate and invertebrate prey were attacked almost immediately. The time interval between presentation of a prey item and the initiation of an attack was so short that it was difficult to measure accurately. Most attacks on vertebrates (77%) were powered. If young mice were not included in the analysis this percentage increased to 91% (50/55). Attacks on_ in- vertebrates were evenly divided between powered and gliding flights (Table 2). This dif- ference in the type of flight used to attack vertebrates and invertebrates was found to be signficant (X’ = 11.92, d.f. = 1, P < 0.001). The difference between vertebrates other than young mice and dead mice and invertebrates was also significant (X? = 8.66, d.f. = P < 0.01). Kestrels killed small invertebrates (grasshoppers, crickets, cicadas, and cockroaches) by removing their heads. The single crayfish presented as a prey item was kill- ed when the kestrel removed parts of the head. Young mice were either ingested whole or killed when parts of their heads were removed. Adult mice were killed by removal of parts of the skull and brain (generally the frontal or occipital regions). House Sparrows were handled in the same way. Dead mice and rats were handled in the same manner as live prey, i.e., parts of the head were removed before other portions were consumed. Thus, both living and dead vertebrates and invertebrates were handled in the same manner. All vertebrate prey items were taken to a perch before being consumed (Table 2). Adult mice, young rats, and House Sparrows were carried in the talons (39/39). Dead mice were carried both in the talons (6/16) and the bill (10/16). All young mice were carried in the bill (37/37). Most invertebrates were consumed on the floor of the aviary (45/65). Of the 20 in- vertebrates taken to a perch, 45% (9/20) were carried in the bill and 5% (11/20) were carried in the talons. Thus vertebrates and invertebrates were handled differently by kestrels, with significantly more vertebrates being taken to a perch before being consumed. (X? = 86.16, d.f.=1, P<40.001). Finally, whereas all large prey (55/55) were taken to a perch before being consumed, only 56% (57/102) of the small prey were taken to a perch (Table 2). This difference vertebrates were classified as powered attacks was also significant (X? = 32.03, d.f.=1, (Table 2). Overall, 71 of 92 attacks on P<0.001).

Approximately 11% (10/92) of all vertebrates were cached while no invertebrates were cached (Table 2). This difference between number of vertebrates and invertebrates cached was significant (X? = 5.71, d.f. = 1, P<40.05). Further, although 14.5% (8/55) of all large prey items were cached, only about 2% (2/102) of the small prey items were cached. This difference between the number of large and small prey items cach- ed was also found to be significant (X* = 7.51, d.f.=1, P<40.01). DISCUSSION American Kestrels were found to attack both vertebrate and invertebrate prey almost immediately upon presentation. Such results may be due to the relatively small size of the aviary used in these experiments. That is, prey were presented within 5 m of kestrels and, at that distance, there probably was little chance that the prey would be able to escape. Sparrowe (11) speculated that kestrels assessed their chances of success before launching an attack. He suggested that it would not be adaptive for kestrels to attack prey immediately or even to attack all prey sighted because in some cases the chances for success would be slight and launching an unsuccessful attack would waste energy. Kestrels were found to attack vertebrates and invertebrates in a significantly different manner. Whereas powered flights were used in attacks on most vertebrates, powered and gliding flights were used equally in attacking in- vertebrates. This difference may be due to dif- ferences in the abilities of vertebrate and in- vertebrate prey to elude a predator. That is, a vertebrate probably is more likely to detect and elude a predator than is an_ invertebrate. Therefore, a kestrel would increase its chances of success by getting to the prey as soon as possible, i.e., using a powered flight. Similar observations have been reported by other in- vestigators (8, 9). These authors noted that at- tacks on vertebrates may be characterized as rapid, head-first dives while attacks on in- vertebrates tend to be slow, braking attacks. Differences in the ability to elude a predator may also explain why some prey were attacked directly (with contact). Kestrels made direct contact with adult mice, young rats, and House Sparrows. When attacking young mice and dead mice, kestrels generally landed next to the prey before attacking. Young mice and dead mice obviously could not escape, therefore, im- mediate contact would not be required for a suc- cessful attack. On the other hand, adult mice and House Sparrows could potentially escape and, therefore, immediate contact would be desirable. When considering only adult mice and House Sparrows, kestrels made direct con- tact significantly more often with vertebrates than with invertebrates. Again, this may relate to the relative abilities of vertebrates and in- vertebrates to elude a predator. However, it should be noted that most invertebrates were also attacked directly (77%). Although in- vertebrates probably cannot detect predators at a distance as well as vertebrates (hence the use of gliding attack by kestrels), once aware of a predator (i.e., a kestrel landing nearby) an in- vertebrate may be able to escape. Thus direct attacks on invertebrates, as well as vertebrates, might increase the chances of a successful at- tack. Once captured, both vertebrates and in- Trans. Kentucky Academy of Science — 46(3-4) 141 vertebrates were killed by removal of all or parts of the head. This may be related to the impor- tance of the head (i.e., brain) in coordinating escape movements. By removing or damaging the brain, a kestrel greatly reduces the chances that the prey will escape. Severing the spinal cord would have the same effect and some in- vestigators have suggested that the tomial tooth might be used to sever the cord (12, 13). Although this may occur in free-living kestrels, such use of the tomial tooth was not observed in this study. Whereas all vertebrate prey were taken toa perch before being consumed, most invertebrate prey were consumed on the floor of the aviary. Further, whereas all large prey were taken to a perch, many of the small prey items were con- sumed on the floor of the aviary. Small prey (e.g. invertebrates) can be consumed quickly. In contrast, eating a large prey item (e.g., an adult vertebrate) takes much longer, not only because of the size difference but also because kestrels frequently remove some of the fur or feathers before consuming mammalian and avian prey, respectively. Reduced time on the ground may reduce the likelihood that other potential prey in the area will detect the kestrel and, thus, in- crease the chances of success in subsequent at- tacks. If true, the tendency for kestrels to carry young mice to a perch is difficult to explain. Such mice could.be consumed quickly (6 were ingested whole) so the advantage of carrying them to a perch is not clear. All adult mice, young rats, and House Sparrows were carried with the talons while young mice and most dead mice were carried in the bill. Those prey carried in the talons would appear to be those most like- ly to escape or, possibly, to harm a kestrel. Prey carried in the talons (as opposed to the bill) pro- bably are less likely to escape or harm a kestrel as they struggle. Only vertebrate prey were cached by kestrels and most of these were “large” prey. Of the 10 items cached, 8 were adult mice and 2 were young mice. Rijnsdorp et al. (14) suggested 2 possible reasons for caching: (1) if prey availability varies temporally, caching would allow a kestrel to continue hunting rather than spending time to feed, and (2) by caching large prey items, kestrels can maintain a lower body weight during periods when they are actively hunting (thereby conserving energy). The results of the present study seem to support these hypotheses since, as just noted, most prey cach- ed by kestrels were “large ” prey (adult mice). In conclusion, the results of this study sug- gest that American Kestrels do utilize different types of attacks for vertebrate and invertebrate prey and also handle these two types of prey items differently after a successful attack. Such differences apparently relate to (1) differences in the abilities of vertebrates and invertebrates to detect and elude a predator, and (2) differences in the average size of vertebrate and in- vertebrate prey. These behavioral differences ex- hibited by kestrels appear to (1) increase the chances of further successful attacks, (2) in- crease the chances of successful attacks within an area, (3) reduce the chances that prey will escape once captured, and (4) both increase the time available for hunting and reduce the energy expended while hunting.

Kentucky Academy of Science — 46(3-4) 143 NOTES June 1927 in Austin, Texas, Robert Andrew Kuehne was graduated from Southern Methodist University in 1949, and in 1950 earned an M.S. Degree at the same institution. Prior to enrollment in graduate school at the University of Michigan in 1954, he worked as an aquatic biologist for the Texas Department of Parks and Wildlife. He earned the PhD degree in the spring of 1958, taught a summer session at Michigan State in 1958, and joined the faculty of the University of Kentucky in the fall of 1958 as an Instructor. I first met Bob in the fall of 1959 when I returned from a two-year sojourn in Indonesia. | found him to be an extremely congenial individual, with a tremen- dous store of knowledge of fishes and their way of life. Bob was always willing, sometimes to his own detri- ment, to go the last mile out of his way to assist some- one in need, be it student, faculty member, friend, or some stranger in need of help. Rarely does one en- counter such a compassionate individual. To my knowledge, Bob served as chairman for three doctoral and nine master’s candidates, and played a substantial role in three additional doctoral and six master’s degrees. Bob is senior author of The American Darters. He did essentially all the writing and research, and played a major role in finding darters to photograph. My role was minor; I helped catch most of the fishes, phototgraphed them, and helped in organizing, map making, editing, and proof-reading. Obviously, Bob was the prime mover, I the assistant. The labors to bring the book to fruition were enor- mous, and covered a span of about fifteen years and many thousands of miles of travel. We were often cold, wet, hungry, and dog-tired, but I never once saw Bob Kuehne angry, upset, or even particularly disturbed. Aside from The American Darters Bob had some twenty five papers published in various journals; the number would have been substantially larger had he allowed his student’s papers to bear his name. He refused to do so, although he guided the research and worked side by side with the student. Bob was always willing to help a student, a col- league, or a group thereof, and these activities took an inordinate amount of his time. He received the prestigious “Distinguished Teacher Award” from the Kentucky Student Govern- ment in 1978. Bob was an outstanding teacher, loved by both students and colleagues, and he will be sorely missed. During a visit to his bedside just a few days before he passed away, he asked for my hand, gripped it firmly, and told me that for several years he had often thought of me as an older brother. Neither of us knew that the other felt the same closeness. Bob died 18 December 1984, after a brief illness. All of us who knew him are the better for his having crossed our paths, and his passing left a void that can never be filled. —Roger W.

Distribution of the European Hornet in Kentucky—The number of inquiries received by University of Kentucky insect diagnostic laboratories concerning the European hornet, Vespa crabro ger- mana Christ, increased sharply in 1984. This insect in- troduced into the United States ca. 1840-1860 (Shaw and Weidhaas, J. Econ. Entolmol. 49:275, 1956) is known to have occurred in Kentucky as early as 1958 (USDA, CEIR 8:466, 1958). The distribution of V. crabro germana according to published reports is limited to 14 counties in south central Kentucky. This report combines information from the two published reports with records of the University of Kentucky survey entomologists and insect diagnostic laboratories to provide the most current known distribution of V. crabro in Kentucky. The earliest record of V. crabro germana in Ken- tucky is a 1958 distribution map, illustrating the wasp present in Rockcastle Co. (USDA, CEIR 8:466, 1958). In 1967, 13 additional counties, Bell, Boyle, Butler, Casey, Estill, Knox, Laurel, Lincoln, Madison, Pulaski, Taylor, Whitley and Wolfe were added to the distribution (IBID 23:172, 1973). An additional map 144 Academy Affairs was developed for 1973 but no new Kentucky records were added. Six counties were added to the known distribution of V. crabro germana during 1975-80. Specimens from these counties (county-year of report) Barren-1977, Green-1979, Hopkins-1979, Muhlenberg-1979, Trigg-1980, and Washington-1978 were diagnosed by U.K. survey entomologists. During 1984, V. crabro samples were diagnosed from 19 additional counties: Bourbon, Bullitt, Fayette, Caldwell, Calloway, Christian, Crittenden, Daviess, Grant, Grayson, Hart, Lee, Lewis, Logan, Lyon, Owen, Rowan, Russell, and Wayne. In addition to these confirmed collections, an in- formal survey of County Extension Agents for Agriculture (U.K.-C.E.S.) indicates the distribution of V. crabro may be even more widespread. Our knowledge of the distribution of this insect is probably more closely related to V. crabro germana coming in- to contact with humans than to its true distribution. Although the wasp will nest in attics, barn lofts, etc., it more naturally occupies hollow trees that may be far removed from human habitations— Douglas W. Johnson and Rudy A.

Sisk surveyed the ichthyofauna of Clarks River in western Kentucky and reported a total of 61 species of fishes (Trans. Ky. Acad. Sci. 30:54-59, 1969). Prior to and subsequent to his survey, 13 additional species were reported from the drainage by various authors (Hubbs, Occas. Pap. Mus. Zool. Univ. Mich. 530:1-30, 1951; Page and Smith, Copeia 1976:532-541, 1976; Bauer and Branson, Trans. Ky. Acad. Sci. 40:53-55, 1979, Burr and Mayden, Trans. Ky. Acad.

Sci. 44:125-128, 1983; and Warren and Cicerello, Brimleyana 9:97-109, 1983{1984)). A compilation of distributional records taken from our own survey efforts and the unpublished collections of various other workers (fide Brooks M. Burr) in the drainage yielded a total of 57 collections from the main channels of both East and West Forks, as well as from various tributaries, wetlands, and springs. These collections resulted in the addition of 13 species previously unknown from Clarks River and extended the known distributions of 20 other species to one and/or both forks of the system (Table 1). Presently 87 fish species are documented from the drainage. Table 1.

The discovery of Notropis lutrensis in the West Fork in the summer of 1984 may be indicative of habitat modification and degradation in this recently re-channelized arm of Clarks River. This aggressive, ecologically tolerant ‘The investigation reported in this paper (No. 85-7-44) is in connection with a project of the Kentucky Agricultural Experiment Station and is published with approval of the Director Trans. Kentucky Academy of Science — 46(3-4) 145 shiner has recently expanded its range eastward in both Illinois and Indiana (Smith, The Fishes of II- linois, Univ. Illinois Press, Urbana, 1979), and may ultimately replace less tolerant members of the native ichthyofauna and displace close relatives (e.g., Notropis whipplei) through hybridization and com- petition (Page and Smith, Ill. St. Acad. Sci. Trans. 63:264-272, 1970). To our knowledge, this is the first record of the red shiner in the Tennessee River drainage. The eastward spread in Kentucky of the red shiner may be expected (see Burr et al., 1980) as habitat in other rivers and streams are degraded by man’s activities. The discovery in Clarks River of Percina ouachitae and Etheostoma histrio is of interest because these species are listed as of undetermined status and threatened, respectively, within the state (Branson et al., Trans. Ky. Acad. Sci. 42:77-89, 1981). Based on our observations of the large populations of these species in both West and lower East Forks of Clarks River, and their widespread occurrence in the lower Green River (Warren, Trans. Ky. Acad. Sci. 43:21-26, 1982) and much of extreme western Kentucky (Burr 1980), we feel their retention on the state list of en- dangered and threatened species is unwarranted. Other species for which we cite records (Table 1), and which are recognized by Branson et al. (1981), are Elassoma zonatum and Lepomis marginatus. Exten- sive clearing and drainage of wetlands in Clarks River suggests the continued existence of these wetland- inhabiting species is uncertain. In compilation of the records comprising this note, 2 enigmatic records came to light. Sisk (1969) reported Notropis spilopterus from the West Fork; however, voucher specimens have not been located. Subsequent workers (Bauer and Branson 1979), in- cluding the authors, have collected only the closely related Notropis whipplei from Clarks River. We regard Sisk’s record as unsubstantiated. Clay’s (The Fishes of Kentucky, Ky. Dept. Fish Wildl. Res., Frankfort, 1975) report of Etheostoma asprigene in Clarks River was based on a misidentification of E. neopterum (fide Brooks M. Burr). Our report of E. asprigene in Clarks River is the first substantiated record. We wish to thank Dr. Brooks M. Burr, Southern II- linois University at Carbondale, for providing records and editorial comments, and Mr. Richard R. Hannan, Director, Kentucky Nature Preserves Commission, for providing field assistance—Bernard R. Kuhajda and Melvin L.

Thlaspi alliaceum (Cruciferae) in Kentucky and Indiana— Two introduced species of Thlaspi are widespread in the U.S. A third species, T. alliaceum L., has recently been found by us in Kentucky and In- diana as “new” for these states and for the standard northeastern U.S. floristic manuals (Fernald, Gray’s Manual of Botany, 8th ed., American Book Co., New York, 1950; Gleason, The New Britton and Brown II- lustrated Flora of the Northeastern United States and Adjacent Canada, New York Botanical Garden, New York, 1952; Gleason and Cronquist, Manual of Vascular Plants of Northeastern United States and Adjacent Canada, Van Nostrand, Princeton, N.J., 1963). The only U.S. manual we have noted to ac- count for the species is that for the Carolinas (Radford et al., Manual of the Vascular Flora of the Carolinas, Univ. N.C. Press, Chapel Hill, 1968), which ascribes the species to one county in North Carolina; the earlier Carolina guide (Radford et al., Guide to the Vascular Flora of the Carolinas, Book Exchange, Univ. N.C., 1964) and atlas (Radford et al., Atlas of the Vascular Flora of the Carolinas, N.C. Agr. Exp. Sta. Tech. Bull. 165, 1965) do not include the species. Rollins (J. Arnold Arbor. 62:517-540, 1980), in his ar- ticle on cruciferous weeds in North America does not mention T. alliaceum, nor does the FNA checklist (Shetler and Skog, Eds., A Provisional Checklist of Species for Flora North America, Missouri Bot. Gard. Monog. Syst. Bot. 1, 1978). The species is in the Penn- sylvania atlas — 1 county (Wherry et al., Atlas of the Pennsylvania Flora, Morris Arboretum, Philadelphia, 1979), the Kartesz and Kartesz checklist (A Synonymized Checklist of the Vascular Flora of the United States, Canada, and Greenland, Univ. N.C. Press, Chapel Hill, 1980), and the National List of Scientific Plant Names (Soil Conservation Service, U.S.D.A., Washington D.C., 1982). We have collected T. alliaceum in 4 counties (Campbell, Harrison, Kenton, and Pendleton) in nor- thern Kentucky, 1 county (Pike) in eastern Kentucky, and 1 county (Dearborn) in southeastern Indiana; the vouchers are in the NKU Herbarium (KNK). Some of our northern Kentucky collections were made within about 3 km from the Ohio border; the species almost certainly grows in Ohio, but our searches for it there have so far been unsuccessful. That we have the species from Pike County, Kentucky—the state’s easternmost county—at a site about 30 km from Virginia and West Virginia suggests that it is probably in those states too. Thlaspi alliaceum grows in fallow fields and pastures and along roadsides, often with the other 2 naturalized Thlaspi species. In northern Kentucky the plant is quite infrequent although it may be common locally. Part of the vernal flora, the plants are dead and brown by mid-May. When crushed, T. alliaceum has a strong garlic odor—thus its specific epithet. Such an odor is present, but to a lesser degree, in T. arvense. Our first collections of T. alliaceum (1982 and 1984) were identified as T. perfoliatum. We relied on Fernald (loc. cit.), Gleason (loc. cit.), and Gleason and Cron- quist (loc. cit.) for identification, being unaware that 146 Academy Affairs our plant is missing from these works. In spring 1985, as we became more uncertain as to the plant’s identi- ty, we made additional collections. Finally we deter- mined it to our satisfaction through the European flora (Flora Europaea 1, 1964) and the British flora (Clapham et al., Flora of the British Isles, Univ. Press, Cambridge, 1962). Features useful to distinguish among the three Thlaspi species introduced into the U.S. are: stem vestiture, fruit size, and seed characteristics (at 15X). Thlaspi alliaceum Stem base with long hairs (Fig. 2) (sometimes nearly glabrous on older plants): Fruits 5-8 mm long, 3-4 mm wide, 3 mm thick, the wing to 1 mm wide (Fig. 4, 7). Seeds reticulate, brown (Fig. 10). Thlaspi arvense Stem base glabrous. Fruits 9-15 mm long, 7-12 mm wide, 2 mm thick, the wing to 4 mm wide (Fig. 5, 8). Seeds concentrically ridged, brown (Fig. 11). Thlaspi perfoliatum Stem base glabrous. Fruits 4-6 mm long, 2-4 mm wide, 2 mm thick, the wing to 1 mm wide (Fig. 3, 6). Seeds essentially smooth, yellow (Fig. 9).—John W. Thieret and John R.

Seeking help and comfort in beginning this task I turned to the records of the Academy as preserved in the Transactions. A planned hour or two examining early volumes turned into several afternoons of enjoyable and stimulating reading and an appreciation of our organizations history and heritage. An impressive thread of sound achievement in research is documented, as one would expect, but what caught my attention was a significant pattern of the membership and officers mak- ing suggestions, taking stands and supporting issues that were either contemporary or well ahead of the time and that thrust has continued to the present. At the Fourth Annual Meeting, Academy President A.M. Miller (1) discussed the origin and antiquity of man and the membership subsequently supported the teaching of organic evolution and freedom of scientific in- quiry, teaching and research by resolution (2) at a time in the south-central states when such a stand was not the mode of the day (re the Scope’s trial in Tennessee). At the Thirteenth Annual Meeting, the President of KAS, A.R. Middleton (3), strongly rebuked suggestions that evolutionary teachings were detrimental to religious con- victions of students. The Academy has not retreated from the conflict in this regard as is attested by the work of Wallace Dixon’s (4) Ad Hoc Committee report and the KAS resolution concerning Scientific Creationism. Early in the history of KAS attempts were made to influence the State Legislature to support science and the Legislative Committee headed by C. H. Shull (5) developed a proposal that included requests that the legislature pass a bill providing $1000 for publication of the Tranactions, enact a law to increase the teaching of science in high schools and to compel school boards to appropriate more for equipment and materials for science. The state government was also asked to establish an annual prize for research work. Those efforts, far from being successful, have remained a priority of the membership. Through the development of research en- dowments the Academy has lead the way in attempting to stimulate and recognize research. The initiation in 1978 of joint efforts between the Academy, Legislative Research Commission and the Council on Higher Educa- tion to assess the status of research support has been a significant effort and documents the long and arduous task ahead of the Commonwealth concerning science development and support (6,7,8). Paper presentations, published abstracts and research articles compiled in our journal continually have shown great foresight in research areas of the future that could impact the economic development of the state. The potential of oil shale development was alluded to by Gardner (9) and more recently the 1981 annual meeting’s plenary session and banquet address featured the topic of genetic engineering that we now see as a potential strategy developing an alternative to this state’s dependency upon smoking tobacco as a significant part of the farm economy. Much of what is known concerning the diversity of Kentucky’s flora and fauna is preserved within the bound volumes of the Transactions providing immense base-line data for contemporary analysis of the problems facing man and nature. While we may question the magnitude and depth of research ef- forts Within the state, there is no dispute that the KAS through its paper sessons, symposia, plenary sessions and publications has provided a treasure trove of material for future scientists to improve upon. Trans. Kentucky Academy of Science — 46(3-4) 149 As I contemplated the past record of achievements there are admittedly indications of efforts which were not successful. I also perceived a condition that, at first, seemed to show a glaring weakness of the Academy. That particular item is the independent and separate makeup of the Academy via its diverse membership which represents numerous separate disciples of science. Since the early 1930’s the organization has not been dominated by any one institution in terms of the composition of elected officers (in fact since 1934 the 51 presidents have represented 14 different institutions). | would propose, however, that this seemingly lack of unified institutional clout so important in dealing with budgetary considerations via the Legislature, Council of Higher Education, Federal granting agencies and private foundations is now one of the Academy’s best assets. This rebuttal of my initial statement on this topic comes from a new perception that since the KAS is so free of institutional bias we have important credibility when commenting, suggesting or implementing changes that ef- fect the science status of Kentucky. It is in this vein that I would like to address a view from the Presidency of The Academy concerning both immediate and long-term goals of our organization. All of the current membership are well aware of the efforts of the Academy to develop better and closer ties between science, industry and government. Your support and the tremendous hard work by various committees as well as the officers have built a foundation that will continue to improve such relationships. Financially, the Academy is slowly building toward a stability that will ensure both successful administrative and publication functions and support of basic research. Your elected officers are committed to continue in the direction of fiscal stability. The above goals are consistent with our charge, but now it is also evident that a need exists which, while trying our patience and stamina, is indeed a worthwhile and logical extension of the Academy’s heritage. That need is to help provide a rebirth of the spirit of inquiry at the secondary and elementary school levels as well as among the lay citizens of the Commonwealth of Kentucky. I am indebted to Bill Hettinger of Ashland Oil for the initial stimulus to address this issue of the spirit (or lack thereof) of inquiry as a basic component of both education and direction for society. While among scientists it is not required that I remind you of the scientific method, I would perhaps be remiss by not summarizing an ex- planation of the scientific method by Mueller (10) who wrote “Fundamentally requisite as a basis for wise deci- sions is the scientific method. This consists, in simplest terms, in examining every question in a spirit of search- ing, creative objectivity. For this purpose there should be freedom from all authoritarianism, dogma, and (what is worst of all) conscious deception; and ample scope for honest criticism and counter-criticism. It is carried out by the activity of wide-roving imagination, harnessed speculation, ruthless analysis, coordination with other relevant knowledge from no matter how remote-seeming a sphere, discerning calculation, enlightened observa- tion, versatile probing, and well-designed testing”. One can not question that such a procedure is demanded for every endeavor of human understanding. The obvious question is how shall the Kentucky Academy of Science be a force in promoting the spirit of inquiry? It is my impression that a great opportunity now exists for meaningful changes in both the training of teachers of science and in the expectations of student performance in all subjects. By emphasis on the indepen- dent credibility and objectivity of our membership the Academy can have a leading role in the decision making processes at the state level. Two of the Academy’s more active components; the Junior Academy and the Science Education Committee have proven records of accomplishment and are bound to play still a greater role in the future. A key word today in education and other facets of state government is citizen’s participation. Although we the Academy have a vested interest in science, our interest is slanted toward a science not geared toward any particular institution funded by the public. Utilizing our experience from operating the scientific method we should prove to be very credible in being active participants in drafting the needed changes for the state’s educational endeavors. No single legislated institution alone can develop that spirit of inquiry. Therefore I propose that the membership actively participate by supporting local advisory groups as well as the programs that are being planned by the Academy in the near future. It seems logical that our synthesis of science, industry and government that has been the major theme of KAS annual meetings over the part 3 years now aim toward addressing the issue of science and education. This will be the thrust of symposia and plenary sessions over the next two years. I feel most fortunate to have the opportunity to associate with so many fine people who are active members of the Kentucky Academy of Science. The dedication and commitment to bring forth excellence via the science community shown by the membership is both inspirational and humbling. The membership role shows dedicated stewardship that has enabled our organization to persist for over 70 years. I found comfort in reading C. J. Robinson’s (11) minutes of the organizational meeting of the Academy where he recorded comments made by Stanley Coulter of Purdue University, the principal speaker at that meeting in 1914. In speaking of “Science and State” Coulter said “The relation involves a mutual duty, offers opportunities and opens splendid possibilities”. I will be so bold to add that as part of our mutual duty we can provide the spark and catalyst to generate a new spirit of inquiry for future generations in Kentucky. Respectfully submitted, Joe E.

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, acknowledgements, 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 com- plete 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, Acknowledgements, 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 5x 7 or 8x 10 inches. Line drawings in India ink on white paper are acceptable, but should be no larger than 81/2 x 11 inches. Photographs should have good con- trast 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 guidelines 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 expen- sive and costs will be borne by the author. Reprints are to be ordered when the galley proofs are returned by the Editor.
