Deer Antler Characteristics in Relation to Land Use and Spatio-temporal Factors in Missouri Deer antler growth is influenced by the environment, population density, genetics, and nutrition. As land use and densities change over time, antler characteristics are hypothesized to also change. We examined how geography, land use, and the number of deer harvested per unit area (i.e., harvest density) related to white-tailed deer (Odocoileus virginianus) antler characteristics of harvested yearling bucks in Missouri during 2 time periods (1951-1970 and 1997-2001). Latitude related positively to antler characteristics in the early time period. Robert E. Kissell, Jr., Christopher G. Wieberg, Lonnie Hansen, Jeff Beringer

Cooper's Hawk Non-breeding Habitat Use and Home Range in Southwestern Tennessee There has been considerable interest in the ecology of Cooper's hawks (Accipiter cooperii) in the Southeast since Stoddard's work in the 1930s on northern bobwhites (Colinus virginianus) identified Cooper's hawks as one of the key predators on bobwhites. Understanding Cooper's hawk-bobwhite relationships has become increasingly important as bobwhite populations have declined and Cooper's hawk populations have increased over the past 30 years.

Chemical Restraint of the Fisher As fisher (Martes pennanti) populations recover throughout portions of their historic distribution in the southeastern United States, responsibilities and opportunities in their conservation research likely will become more prevalent. Chemical restraint often is a valuable tool in studying wildlife populations. We reviewed previous research on chemical restraint of fishers with the objective of providing a comparative assessment of field and clinical applications of specific chemical restraints or chemical restraint combinations.

Bat Activity in Upland and Riparian Habitats in the Georgia Piedmont Detailed knowledge of habitat use patterns of forest bats in the southeastern United States is needed to predict how habitat changes from forest management and other land use practices affect bat communities. We used Anabat detectors to survey bat activity on the Oconee National Forest, Georgia, among 3 loblolly pine (Pinus taeda) stand ages (clearcut, sapling, and mature) and 3 riparian habitat types (creeks, rivers, and open wetlands). We used echolocation calls to assess differences in relative activity and species richness among stand ages and riparian habitat types. Amanda M. Ellis, Laura L. Patton, Steven B. Castleberry

Attitudes of South Carolina Youth Towards Aquatic Resources and Recreational Fishing This study assessed South Carolina youths' attitudes toward, opinions on, knowledge of, and priorities toward South Carolina aquatic resources and recreational fishing. A telephone survey was administered to youth between the ages of 8 and 18 in South Carolina during April 2001 to examine fishing initiation, motivation, and fishing participation rates among South Carolina youth. Overall, a majority of youth (91%) in South Carolina had fished at least 1 time in their lives and a majority (53%) of youth would go fishing more often if they could. Mark D. Duda, Peter E.

Atlantic Tarpon Distribution in Brackish-water Lagoons, Humacao Natural Reserve, Puerto Rico Atlantic tarpon Megalops atlanticus is an important recreational fisheries resource in the 6 brackish water lagoons located in Puerto Rico's Humacao Natural Reserve. The lagoons, which formed on the reserve after Hurricane David and Tropical Storm Frederick flooded the area in August 1979, are arranged in series and connect to the sea during periods of substantial precipitation. Subsequently, they reflect environmental gradients from essentially marine to low-salinity brackish water conditions. Kirk R. Rundle, Donald C. Jackson, Eric D. Dibble, Orlando Ferrer

An Analysis of Mississippi Conservation Officer Satisfaction with Weaponless Tactics Training A survey was developed and administered to a population of Mississippi conservation law enforcement officers in order to elicit demographic characteristics and satisfaction with weaponless tactics training. One hundred and four of 253 (41%) surveys were returned for analysis. Respondents were classified based on having <5 years, 5-15 years, or >15 years service. In general, officers with more experience were likely to find weaponless tactics training important but only moderately so. Richard B. Minnis, Patrick L. Parker

A Survey of Urban Deer Policies in 4 Southeastern States In the 20th Century, white-tailed deer (Odocoileus virginianus) populations in the United States increased dramatically. In many states, management objectives for deer have changed from conserve and increase to control and decrease. Diversity among stakeholder's objectives for deer populations has made management difficult. Many states in the northeastern and midwestern United States began struggling with urban deer management in the 1980s, whereas southeastern states have only recently encountered this challenge.

A Survey for Prevalence of Paramoeba spp. in Blue Crabs along the Atlantic and Gulf Coasts Paramoeba perniciosa is a parasite that has been found in blue crabs Callinectes sapidus from coastal embayments from Florida to Connecticut and has been associated with mortalities in crab shedding facilities in coastal bays of Maryland and Virginia. Hemolymph samples from more than 7300 crabs over a 9-year period from the Gulf (N = 228) and Atlantic (N = 7167) coasts of the United States revealed 0.5% of crabs assayed to be infected by P. perniciosa.

A 50-year History of the Southern Division American Fisheries Society We evaluated the accomplishments of the past 50 years of the Southern Division American Fisheries Society (SDAFS). We used minutes from the Southern Division annual meetings and various records to view past issues addressed by the division and activities of the SDAFS technical committees and chapters, and the evolution of the SDAFS annual meeting. Since its formation in 1952, the SDAFS has grown to about 2,000 members with 8 active technical committees, 20 chapters, and 8 student units. Mike S. Allen, Mike J. Van Den Avyle, Richard L.

Briery Creek Lake is a 342-ha impoundment in central Virginia that has become widely recognized as having Virginia's premier trophy largemouth bass (Micropterus salmoides) fishery. We estimated largemouth bass density (fish/ha) using a multiple census mark-recapture technique along a 3.2-km section of shoreline and by using the Leslie catch-depletion technique in a 4.1-ha cove. An access point creel survey was conducted in 1999 and 2000 to estimate angler catch and harvest. Victor J. DiCenzo, Daniel A. Garren

A Precocious Population of Channel Catfish with Potential as a Research Model A population of catfish presumptively identified as channel catfish (Ictalurus punctatus) found in Lake Maurepas in southeast Louisiana matures at a small size and early age (<170 mm TL and <2 years) compared to other populations in southern Louisiana (>500 mm TL and 3 to 4 years). In addition, these catfish have a protracted spawning period. The peak spawning time coincides with cultured channel catfish, but a percentage of the population spawns throughout the summer months. These fish are harvested at a small size and support an important but contentious commercial fishery. Mark C. Bates, Terrence R. Tiersch, Quiyang Zhang, Mark G. McElroy

Aquatic Investigations and Recovery The Aquatic Investigation and Recovery team of the South Carolina Department of Natural Resources is a 12-member team that is responsible for the recoveries of as well as provides investigative assistance for many water related fatalities in the state of South Carolina. Three specific incidents are discussed here. The first being the 1994 Susan Smith case, when a mother murdered her two children by allowing her vehicle to roll into Lake John D. Long in Union County, S.C. The second occurred in 1996, also in Lake John D.

Assessment of a 178-mm Minimum Length Limit on Bluegill at Purtis Creek State Park Lake, Texas We compared relative abundance, size distribution, growth, and harvest of bluegill (Lepomis macrochirus) before and after implementation of a 178-mm minimum length limit at 144-ha Purtis Creek State Park Lake (PCSPL), Texas. Relative abundance [catch/hour of electrofishing (CPUE)] was significantly lower in post-regulation years (1993-1995, 243/hour) than in pre-regulation years (1990-1992, 520/hour). However, this decline was likely more attributed to recruitment patterns than to regulation effects. Richard A. Ott, Jr., Timothy J. Bister, J. Warren Schlechte

Biochemical Genetics of Brook Trout in Georgia: Management Implications Twenty-eight populations of brook trout (Salvelinus fontinalis) in Georgia were genetically compared using isozymes and their genetic relatedness determined. Eight populations (29%) were classified as southern based on fixation for CK-A2*122 allele, 2 (7%) populations were classified as northern based on fixation for CK-A2*100 allele, and the remaining 18 (64%) were northern-southern hybrid populations. All 8 southern populations shared some variant alleles with northern populations. Rex A. Dunham, Huseyin Kucuktas, Zhanjiang Liu, Lee Keefer, Michael Spencer

Bobcat Home Range Size Relative to Habitat Quality Bobcat (Lynx rufus) home range is generally considered to be a function of habitat quality, but there have been few published studies that explicitly address this idea. We used empirically developed bobcat habitat models to predict habitat quality within bobcat home ranges on 2 study areas in central Mississippi. We then assessed the relationship between home range size and habitat quality. Habitat quality and variability of habitat quality were not (P>0.10) predictors of home range size. L.

Comparison of Feeding Regime and Diet on Compensatory Growth of Hybrid Bluegill We conducted 2 experiments to evaluate the potential of feeding schedules designed to elicit compensatory growth and increase growth of hybrid bluegill (F1: male bluegill Lepomis macrochirus x female L. cyanellus). The first experiment evaluated a commercially prepared pellet and consisted of 3 treatments: fish fed every day and fish starved for 2 or 4 days after cessation of hyperphagia. The second experiment evaluated 2 diets, mealworms and commercial pellets, fed every day and on a 2-day starvation schedule. Clifton R. Sager, Dana L. Winkelman

Comparison of In-Water Voltage Gradients Produced by Electrofishing Boats The voltage gradients of electric fields produced by electrofishing boats are important in determining sampling efficiency and the potential for injuring fish. We evaluated 10 electrofishing boats and found that 3 boats had malfunctions that could impact sampling or operator safety. The in-water voltage gradients were measured for the remaining 7 boats to make comparisons among boats and to determine the voltage gradients present during electrofishing. Theodore B. Henry, John M.

Comparison of Reclaimed and Unmined Woodcock Summer Diurnal Habitat in West Virginia Reclaimed surface mines are used by American woodcock (Scolopax minor) as diurnal habitat during summer in West Virginia. However, habitat quality of these sites relative to that of other (unmined) diurnal habitat in West Virginia has not been previously evaluated, making it difficult to assess the potential for using mine reclamation to create woodcock habitat.

Development of a Bioenergetics Model for Appalachian Brook Trout In many Appalachian headwater streams brook trout (Salvelinus fontinalis) are the only fish species present. Land use practices or global warming can have a significant effect on the production and survival of brook trout in these streams. Managers must be able to evaluate the potential impact of thermal changes upon these streams and bioenergetics models represent a valuable tool in this effort. Here we present a bioenergetics model for brook trout and conduct a laboratory validation of the model.

Drumming Log Habitat Selection by Male Ruffed Grouse in North Carolina We evaluated ruffed grouse Bonasa umbellus drumming logs in western North Carolina to determine criteria used by male grouse in selecting drumming sites. For every drumming log found (N = 34), we selected a random log within the same stand type and with a similar topographic position. We collected data on drumming log characteristics and on vegetation surrounding the drumming site. Carrie L. Schumacher, Craig A. Harper, David A. Buehler, Gordon S. Warburton, William G. Hinser, III

Effect of Calcium Hardness on Channel, Blue, and Channel x Blue Catfish Hybrids The aquifer that supplies water to most channel catfish (Ictalurus punctatus) hatcheries in the Yazoo Basin of the Mississippi River flood plain in west-central Mississippi has a hardness of <10 mg/liter as CaCO3. Calcium hardness <10 mg/liter is known to reduce survival and growth of catfish sac and swim-up fry, but effects of low hardness on fingerling growth and survival have not been determined. We examined the effects of hardness (5 mg/liter and 67 mg/liter as CaCO3) on survival and growth of fingerling (2.0-3.2 g initial weight) channel catfish (USDA-103 line), blue catfish (I. Eugene L.

Effect of Winter-diet Restriction on Prebasic Molt in Female Wood Ducks During winters 1990-1992, we manipulated food availability 5%-20% less than that of ad libitum feeding for captive groups of wild-strain North American wood ducks (Aix sponsa) to test effects of increasing levels of food restriction on prebasic molt of females. Birds fed ad libitum and 5%-15% restricted diets exhibited a protracted molt (>90 days) of low intensity. Most females fed a 20%-restricted diet did not initiate molt until resumption of ad libitum food availability. Scott C. Barras, Richard M. Kaminski, Leonard A. Brennan

Lake Tanglewood, Texas, is a eutrophic reservoir with an excessively abundant gizzard shad Dorosoma cepedianum population comprised of primarily large individuals (>180 mm total length [TL]). Fingerling (40 mm TL) hybrid striped bass (Morone saxatilis x M. chrysops) were stocked at high rates in 1992 (490/ha) and 1993 (245/ha) to restructure the gizzard shad population. Small gizzard shad (<180 mm TL) declined in abundance 1 year after hybrid striped bass were introduced, presumably as a result of hybrid striped bass predation. Kenneth G. Ostrand, Harold L. Schramm, Jr., Joseph E. Kraai, Ben Braeutigam

Although fertilization has been a common practice to increase fish production in low nutrient lakes and ponds, applicability of the practice in larger reservoirs is questionable. Under the assumption that increased algal production moves up the food web to fish, we fertilized Grayson Lake, Kentucky, surface water with high N to P ratio fertilizer during springs 1994 and 1995. April through July 1994 we added 1 kg P/ha and 22 kg N/ha over a 9-week period to approximately 162 ha of lake surface area. During 1995 we increased loading to 7 kg P/ha with 22 kg N/ha. Brian C.

In temperate reservoirs, habitat quality and availability can be vital to year-class formation of young largemouth bass. We assessed littoral habitat availability for largemouth bass in a tropical reservoir. Habitat characteristics (slope, substratum, and cover) were measured at 5 water levels (169, 170, 171, 172, and 173 m above mean sea level) at 15 30-m sites in Lucchetti Reservoir. Total structural habitat availability declined sharply at lower water levels, and both inundated terrestrial vegetation and woody debris were absent at the lowest water level examined. J.

Environmental Influences on Largemouth Bass Recruitment in a Southern Great Plains Reservoir We analyzed relationships between largemouth bass (Micropterus salmoides) recruitment and environmental characteristics in Skiatook Lake, Oklahoma, from 1997 through 1999. Catch rates of young-of-year (YOY) were positively associated with inflows into the reservoir during the spawning season (April-May), whereas juvenile catch rates were positively related to reservoir releases during the post-spawning period (Jun-Nov). Abundance of juvenile fish in fall electrofishing samples increased from 1997 through 1999. No evidence of over-winter mortality was detected. James M. Long, William L. Fisher

Many fisheries management agencies incorporate benthic macroinvertebrate metrics in stream assessment, yet concern exists over regional variability in metric sensitivity and the reproducibility of results over time. Two field experiments were conducted in Mullenax Run, Pocahontas County, West Virginia during summers 1999 and 2000 to investigate the sensitivity of benthic macroinvertebrate metrics to fine sediment and annual variation.

Fall and Winter Brook Trout Prey Selection and Daily Ration Most studies examining salmonid diets and their relationship to invertebrate drift are confined to periods from spring through early fall. Invertebrate drift generally decreases from spring through summer and fall seasons and is greatest during diel periods of low light. Salmonid feeding efficiency is reduced under low light conditions and several studies have found them to feed primarily through the daylight hours. Drift feeding salmonids are also size selective.

Fire Impacts to Small Mammals in Piedmont Oak-shelterwoods Successful regeneration of oaks on better sites (SI50>60) has proven difficult in recent decades due to competition from faster growing species and well-established advanced regeneration from more shade-tolerant species. The suppression of fire is thought to have played a critical role in allowing this largely fire-intolerant competition to dominate many upland hardwood forests at the expense of oaks. Patrick D.

Forest Clearings Management: Insects and Vegetation for Wild Turkey Broods Insects and herbaceous vegetation important to young eastern wild turkeys (Meleagris gallopavo sylvestris) may be enhanced in forested areas by managing clearings. Natural resource agencies in Virginia and other eastern states have committed significant resources to create and maintain forest clearings to provide habitat for wild turkey broods in predominantly forested areas. However, techniques used to manage clearings often lack definitive ecological justifications. Nelson W. Lafon, Gary W. Norman, Jay C. Jeffreys, David E. Steffen, Richard D. Fell

Forest Industry Hunt-lease Programs in the Southern United States: 1999 We evaluated selected characteristics of forest industry hunt-lease programs for the 1999 calendar year in the southern United States. Sixty questionnaires were mailed to wildlife biologists and hunt-lease administrators of various forest industries within these states. Thirty-four completed questionnaires were returned, yielding an overall response rate of 56.7%. Respondents owned 6,006,050 ha; they leased 4,600,611 ha (76.6%) to the private sector and 424,784 ha (7.1%) to the public sector. H. Stroh Morrison, IV, Allan P. C. Marsinko, David C. Guynn, Jr.

Genetic Analysis of Ozark Hellbenders Utilizing RAPD Markers Ozark hellbenders (Cryptobranchus alleganiensis bishopi) are large aquatic salamanders found in flowing waters. The abundance of this species is thought to have declined over the long term. What had been the most abundant population, in Spring River, Arkansas, appears to have declined precipitously in the last decade. The possibility of supplementing the population through captive propagation has been suggested, raising concerns about genetic issues. Huseyin Kucuktas, Brian K.

Brook trout (Salvelinus fontinalis) is the only salmonid native to the southern Appalachian Mountains. The range of brook trout within this region was greatly reduced during the 20th century due to environmental degradation and the introduction of non-native rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta). Efforts to supplement trout populations and to repopulate streams in which trout had been extirpated also included stocking of hatchery-reared brook trout, the stocks for which originated from northern populations.

Geographic Information Systems in Wildlife Law Enforcement Geographic information systems (GIS) have been used in wildlife and fisheries management and research for many years. These systems are not being used, however, to the fullest potential in conservation law enforcement. At present, there are only 5 conservation law enforcement agencies in the United States using GIS. In Mississippi a GIS is being developed for use in conservation law enforcement. Chad M. Dacus, Richard B. Minnis, James Willcutt

Kentucky-31 tall fescue (Festuca arundicacea) was a common planting established on Conservation Reserve Program (CRP) fields throughout the southeastern United States during the late 1980s and 1990s. Fescue-dominated grassland communities on CRP fields offer poor quality nesting, brood-rearing, and foraging habitat for northern bobwhite (Colinus virginianus) because of dense vegetation, high litter cover, low bare ground, and low plant diversity.

On 11 October 2000, approximately 946.25 million liters of coal slurry waste spilled from a Martin County Coal Corporation impoundment into 2 stream drainages in Martin County, Kentucky. On the same day of the spill occurrence, water quality was assessed and periodic monitoring has continued to the present by state personnel from Kentucky and West Virginia. The resulting damage to fish in the streams was the focus of intensive investigation by both the Kentucky Department of Fish and Wildlife Resources and the West Virginia Department of Natural Resources.

Spatial Fidelity of Wild Turkeys Between the Seasons in Central Mississippi Understanding space use patterns of wildlife may be useful to spatially plan habitat management options and understand how species use resources on a landscape. Spatial fidelity can be defined as the tendency of an animal to maintain similar space use patterns among periods of interest and can be described in terms of differences in dispersion of points and shift in central tendency. However, little information is available concerning spatial fidelity in wild turkeys (Meleagris gallopavo). Therefore, we investigated seasonal spatial fidelity of male and female eastern wild turkeys (M. g. Darren A. Miller, L. Mike Conner, Bruce D. Leopold, George A. Hurst

Surveying Nocturnal Bird Communities of the Southeast with Silent and Playback Methods Accurate nocturnal bird abundance and distribution data are necessary for managing nocturnal avian communities. We compared vocalization playback and silent methods for surveying 3 nocturnal avian species in Mississippi in 1997 and 1998. Playback elicited more responses from eastern screech-owls (Otus asio) than the silent method. Playback was more effective than the silent method at detecting habitat associations of eastern screech-owls, which were strongly associated with pine regeneration stands than pine sawtimber stands and pine-hardwood stands.

Status and Management of Endangered Bats in Kentucky Three species of bats are endangered in Kentucky: the Indiana bat (Myotis sodalis), the gray bat (M. grisescens), and the Virginia big-eared bat (Corynorhinus townsendii virginianus). Because some level of monitoring of these bats has taken place at Kentucky caves for several decades, trends can be assessed and some effects of management practices can be evaluated. In Kentucky, populations of Indiana bats continue to decline despite numerous protection efforts, populations of gray bats appear stable, and populations of Virginia big-eared bats are increasing.

Allegheny woodrat (neotoma magister) populations in the northern and western limits of the range have been greatly reduced in recent years, increasing the need to locate and monitor both threatened and seemingly stable populations. We tested the feasibility of predicting areas of suitable habitat for the woodrat in the Daniel Boone National Forest (DBNF) by using a Geographic Information System model. Several themes depicting woodrat habitat variables were overlaid to produce a comprehensive map displaying likelihood of woodrat occurrence. Eric S. Ivanovich, Stephen Sumithran, Robert B. Frederick

Response of the Crappie Population to Regulatory Changes in Kentucky Lake, Kentucky: A Case History The objective of this case history was to document the response of the crappie (Pomoxis spp.) population at Kentucky Lake to restrictive harvest regulations. In the late 1980s and early 1990s, crappie abundance declined due to poor recruitment and high mortality during severe drought years. A tagging study estimated minimum exploitation at 45%. Following the drought, restrictive harvest regulations (30 fish creel and 254 mm minimum length limit) were implemented to reduce exploitation, and subsequently increase survival of crappie from age 1 to age 2.

Response of Brown Trout in Lake Cumberland Tailwater to a Trophy Regulation The objective of this study was to evaluate the use of a 508-mm minimum length limit in conjunction with a 1-fish-per-day creel limit to determine its effectiveness in improving the size structure of the brown trout (Salmo trutta) fishery resource in the Lake Cumberland Kentucky tailwater. The ultimate goal is to increase the number of trophy (>508 mm) brown trout within the tailwater. When sample sites were combined, a significant increase in brown trout CPUE was seen across years for all size-classes.

Temporal Change in Fish Assemblages of Triplett Creek, Kentucky Historical records and natural history collections have been used as important tools to determine the status of populations. The objectives of this project were to compile a list of the fishes that have inhabited Triplett Creek and to identify changes in the fish assemblage in Triplett Creek. Historical records and vouchered specimens document 80 species from 19 families in the Triplett Creek system between 1890 and 1998. In a survey of the Triplett Creek system in 1999 and 2000, 16,554 specimens were collected, representing 54 species from 11 families. Katherine A. McCafferty, David J. Eisenhour

Seasonal Movement and Distribution of Smallmouth Bass in a Virginia Impoundment We described seasonal movements of smallmouth bass (Micropterus dolomieu) in Lake Moomaw, a 1,024-ha western Virginia impoundment, using ultrasonic telemetry in combination with a mark-recapture tagging study. Documentation of lake sections occupied over the course of a 2-year period was used to assess the extent and magnitude of spring migrations of bass to the headwaters of the reservoir. Fish using the headwaters during the spring were drawn mainly from adjacent areas within 9 km of the headwaters, although fish from as far away as the dam were recovered in the headwater area.
