Seasonal Use of Clearcuts and Food Plots by White-tailed Deer in the Southern Appalachians We sampled forage and browse and made spotlight counts to study seasonal use of clearcuts and food plots by white-tailed deer (Odocoileus virginianus) in the Southern Appalachians. Browse production was greater in clearcuts than in adjacent forest. Deer used clearcuts most intensively during the summer when green leaves and herbs were abundant. Use of clearcuts was very low in winter. Browsing intensity was higher in clearcuts than in the forest in summer but not in winter. However, less than 4% of all twigs were browsed even in clearcuts in summer. James M. Wentworth, A. S. Johnson, P. E. Hale, K. E. Kammermeyer

Targeting Potential Wildlife Management Cooperators Participants in the Conservation Reserve Program (CRP) in Virginia were surveyed to determine their acceptance of the wildlife management options available. The resulting data were subjected to statistical analysis through logit models to enable prediction of desire to improve wildlife habitat and actual implementation of habitat improvement. The analysis indicated that landowners who retired >16.2 ha or who farmed >40.5 ha were most likely to incorporate wildlife management practices. Edwin J. Miller, P. T. Bromley

Biology of a Feral Hog Population in South Central Florida Ninety-three feral hogs (Sus serofa) collected from July 1978 through June 1979 on the Fisheating Creek Wildlife Refuge in Glades County, Florida, were examined for physical condition, food habits, and reproductive status. Wild hog food habits were determined largely by food availability and nutritional requirements, which changed seasonally. Hogs collected on the study area were in better condition with regard to internal fat during fall and winter but appeared to be under greater stress during these periods as determined by adrenal weights.

White-tailed Deer Use of Small-Area Fuelwood Cuttings in West Virginia Six slash-disposal treatments were applied to 24 O.05-ha plots in a mixed hardwood forest in northern West Virginia to determine white-tailed deer (Odocoileus virginianus) use of small fuelwood cuts. Fuelwood harvest resulted in an increase in woody stems during the first year following cutting, but there was no significant effect by type of slash-disposal treatment on number of stems that regenerated. Deer use, as evidenced by pellet groups, differed among treatment plots, yet no consistent preference for specific treatments was detected. Edwin D. Michael, W. P. Klein, J. M. Dickson

Early Summer Diet of Male Northern Bobwhite in the North Carolina Sandhills Crops from adult male northern bobwhite (Colinus virginianus) were collected May-July 1985 (N = 43) and April-June 1986 (N = 45). Woody plant, legume, and grass seeds accounted for >90% of the total crop volume in both years, but the relative proportions of seed types varied significantly (X2 = 66.38, P <0.005) between years. This was partly due to differences in plant fruiting chronology and seed availability during sample periods, as rye (Secale cereale) was unavailable to most quail collected in 1986. Paul D. Curtis, T. L. Sharpe, P. D. Doerr

Relationship of Wild Turkey Gobbler Movements and Harvest Rates to Management Area Boundaries We monitored 122 radio-equipped wild turkey (Meleagris gallopavo) gobblers on Tallahala Wildlife Management Area (TWMA), Mississippi, during all seasons, 1986-89. Gobblers that had ≥50% of telemetry locations off the area were considered off TWMA. Percent off of the area was greater (P <0.1) in spring than summer 1986. An average of 34% of gobblers was off TWMA during the spring hunting period, 1986-89. We detected no difference in harvest rates between gobblers on and off TWMA. Managers should consider harvest on adjacent private lands when planning for public hunting areas. K. David Godwin, W. E. Palmer, G. A. Hurst, R. L. Kelly

Range Dynamics of Black Bears in Great Dismal Swamp, Virginia-North Carolina Range size and dynamics of black bears (Ursus americanus) were determined in Great Dismal Swamp (GDS), an 850-km2 forested wetland straddling the eastern border of Virginia and North Carolina. Male ranges were larger (P < 0.05) than female ranges annually and seasonally. Median range sizes were 21.4 km2 for adult females (N = 11),33.1 km2 for subadult females (N = 7), and 79.0 km2 for males (N = 10). Extensive fall movements inflated female ranges. Eric C.

Boundary-strip Width for Density Estimation Based on Telemetric Locations The mean maximum distance moved (MMDM) of a southern fox squirrel (Sciurus niger niger) population during a l2-day trapping period was compared between radiotelemetry and capture location data. MMDMs derived from capture locations averaged 51% less than MMDMs derived from telemetric locations. In addition, tests of MMDMs based on capture locations failed to detect a difference between sexes, whereas MMDMs based on telemetric locations indicated a significant difference. Philip A. Tappe, D.

Movements, Habitat Use, and Survival of Wood Duck Broods in East-central Texas During 1978 and 1979, data were collected on wood duck (Aix sponsa) brood movements, habitat use, and survival in east-central Texas. Radio telemetry of 18 broods indicated most broods left the nesting site immediately after exiting nesting structures. Distances traveled from nesting site to brood-rearing site varied from 0.111.7 km. Overall, duckling survival (N = 167) was 8%. However, survival for 40 ducklings that reached adequate brood-rearing habitat was 48%. Kenneth T. Ridlehube, B. W. Cain, N.J. Silvy

Home Range and Habitat Use of Eastern Bluebirds in South Carolina Adulteastem bluebirds (Sialia sialis) were monitored by radio-telemetry during the breeding (5M:5F) and wintering (5M:5F) seasons to obtain home range and habitat data. All birds used natural cavities on forested land in west-central South Carolina. Mean home range size of breeding season bluebirds was 19.2 ± 4.4 ha (¯x ± SE)for males and 13.7 ± 4.4 ha for females. Wintering season home ranges were 105.9 ± 15.5 ha and 120.8 ± 16.6 ha for males and females, respectively. Home ranges did not differ (P >0.05) by sex but did by season.

Response of Wild Turkey Hens to Bear Hunting in Western North Carolina Movements of eastern wild turkey hens (Meleagris gallapavo silvestris) were monitored using radio telemetry on the Coweeta Hydrologic Laboratory in Western North Carolina during 1985-87. Turkeys (N = 15) responded to the use of dogs for bear hunting by temporarily abandoning portions of their established home ranges and relocating to unhunted areas during the 2-month season. Hens returned to abandoned areas soon after hunting ceased and when dogs were not used for hunting. No mortality of turkeys was detected during bear season. Derik J. Reed, D. C. Guynn, Jr.

Day Beds, Natal Dens, and Activity of Florida Panthers Day rest sites and natal dens of Florida panthers (Felis concolor coryi) studied from January 1986 to August 1989 were dominated by dense vegetation, especially saw palmetto (Serenoa repens). Activity peaked around sunrise and sunset for both denning females and solitary panthers; however, solitary panthers exhibited greater extremes in activity and inactivity. Females were most likely to be at the den during daylight and spent about 50% of the denning period at the den. Day beds and den sites are important habitat features and should be considerations in panther management. David S. Maehr, E. D. Land, J. C. Roof, J. W. McCown

Turkey Hunter Satisfaction in Florida Responses from a mail survey of Florida Turkey Stamp purchasers were used to evaluate turkey hunter satisfaction. Using factor analysis, 7 dimensions of hunter satisfaction were interpreted from ratings of 31 aspects of turkey hunting. Individual aspects of turkey hunting poorly correlated with the rating of the overall hunting experience. The 7 dimensions (nature, social, hunting, management, harvest, disturbance, and preparation) accounted for 50% of the variance in responses; individually, dimensions accounted for 9% oftotal variance.

Distribution and Habitat Use of Snow and Whitefronted Geese in Arkansas We used winter aerial survey data to evaluate abundance, distribution, and habitat use of snow (Chen caerulescens caerulescens) and white-fronted geese (Anser alhifrons) wintering in Arkansas' Mississippi Alluvial Valley (MAV). Longterm survey data indicate that numbers of both species have increased more than lO-fold during the past decade, with recent maximum survey counts of 503,000 and 19,000 for snow and white-fronted geese, respectively.

Fawning Date and Growth of Male Alabama White-tailed Deer Male white-tailed deer (Odocoileus virginianus) fawns were collected from the wild at random in Alabama during the springs and summers of 1986 and 1987. Average body weight at 16 months of age was 58.3 kg (5004 to 68.2 kg) and antler weight averaged 150.1 g (25 to 339 g). Yearling weight and date of birth were not related (r = -0.36; P = 0.078) nor were antler mass and date of birth (r = -0.17; P = 00411). Racks averaged 4.2 points (range 2 to 8 points). Point number and date of birth were not related (r = 0.02; P = 0.914).

Bottomland Hardwood Forest Management for Black Bears in Louisiana We studied habitat use by 32 radio-collared black bears (Ursus americanus luteolus) in the Tensas River Basin of Louisiana during April 1988-90. Preliminary data from telemetry and field observations were combined with a literature review to develop bottomland hardwood forest management guidelines for bears on Tensas River National Wildlife Refuge. Logged areas provided feeding, resting, denning, and escape opportunities for bears. Bears used bald cypress (Taxodium distichum), brushpiles, and ground nests for winter dens. Keith M. Weaver, K. K.

Method for Transporting Incubated Giant Canada Goose Eggs We transported 2,220 giant Canada goose (Branta canadensis maxima) eggs by small aircraft from Cornwall, Ontario, Canada, to EI Reno, Oklahoma, from 1986 through 1989. Stages of incubation ranged from 3 to 27 days. Eggs were covered with goose down and shipped in domestic turkey egg transport containers made of corrugated cardboard. Two techniques were used to maintain temperatures between 24 and 38 C. In 1986 and 1989, no attempt was made to heat the eggs other than from the aircraft cabin temperature. Jontie W. Aldrich, B. D.

Plant Response to Moist-soil Management in Southeastern Arkansas We examined plant response to moist-soil management in the delta region of Arkansas in 1985-87. We monitored 3 fields subjected to May, June, and July drawdowns and passive management (no summer irrigation). Total seed production varied from 253 to 1,288 kg/ha and vegetation mass ranged from 1,070 to 4,880 kg/ha. Seed production was more dependent on year and field effects than on drawdown date. Fall panicum (Panicum dichotomiflorum) was the most important seed producer and longpod sesbania (Sesbania macrocarpa) was the major problem species. Timothy J. Moser, S. C. Yaich, G. A. Perkins, R.

An Improved Drop Net for Capturing Wildlife An inexpensive, portable, simplistic, and safe (no blasting caps) drop net was developed and tested on ground-dwelling birds and I deer. The net is held up by tension and is triggered by rapid release ofthe tension. The net was effective on the species tested. Its simple design may lend itself for adaptation for use to capture many species of wildlife. Nova J. Silvy, M. E. Morrow, E. Shanley, Jr., R. D. Slack

Nineteen gray foxes (Urocyon cinereoargenteus) were equipped with radiotransmitter collars and located by triangulation on the Savannah River Site, Aiken, South Carolina, between 22 March 1985 and 24 May 1986. Telemetry locations (N = 3,(08) were used to estimate seasonal home range sizes (N = 23) and calculate minimum total distances (MTD) moved (N = 192). Seasonal home range sizes were not different between sexes or seasons (P > 0.05). Average seasonal home range sizes were 173 ha for males, 139 ha for females, and 158 ha for both sexes combined.

Identifying and Responding to Antihunting Sentiment We compared Texas antihunters with hunters and neutrals in terms of 8 demographic characteristics, their views on 6 reasons for hunting, and opinions on 7 environmental statements. Antihunters were nearly indistinguishable from neutrals in demographic characteristics, levels of opposition to hunting, and environmental opinions. Membership in or desire to become a member of an antihunting organization does not necessarily identify an antihunter as evidenced by a measurable degree of antihunting sentiment among neutrals.

A Low Intervention Program for Weight Loss in Law Enforcement Officers At the request of Texas state game wardens, a low intervention weight-loss program was implemented for 48 officers assigned to 3 law enforcement districts and the department headquarters staff. The program was designed to take advantage of the social interaction and support of wardens assigned to the same unit. At termination of the l4-week program, 90% of the participants had lost weight and mean weight loss for all officers was 8.6Ib. Weight-loss was related to initial weight of participants and to the district of assignment.

The Georgia Department of Natural Resources is currently in the process of upgrading its law enforcement services through advanced training in the area of defensive tactics. One of the objectives of this mission is to certify each of Georgia's conservation law enforcement officers in the use of an intermediate weapon in an effort to have a complete line of force options available to its law enforcement personnel. In an attempt to fill this void, the Department has selected one of the most highly advanced intermediate weapons available to law enforcement today, the tactical baton.

Familiarization Training with a New Weapon and Night Sights The difference between surviving or not surviving a shoot-out will depend on many factors. Who are you up against, how many are you up against, how efficient are they, and then, how efficient are you? This could be the most important question you could ever ask yourself in a life or death situation. Nothing could be more important when confronted with a violent situation than training and equipment. Proper training and equipment are a must for a professional law enforcement officer, anything less is only flirting with danger.

Bird Kills in Contained Oil: A Biopolitical/ Enforcement Strategy Extensive bird mortality was documented from oil contained in pits and opentopped tanks in New Mexico, Oklahoma, and Texas. Annual mortality easily exceeded 300,000 birds including 100,000 ducks. An enforcement strategy was developed that included negotiations with state oil regulating agencies, seminars presented to oil industry associations, a news media campaign, and criminal and civil enforcement actions initiated at the state and federal level.

Effects of Brush Reefs on Distribution of Fish in Florida Lake This study describes a method of constructing inexpensive, durable, shallow-water reefs in freshwater lakes with whole Australian pines (Casuarina spp.). Snorkel observations demonstrated that largemouth bass (Micropterus salmoides), bluegill (Lepomis macrochirus), and redear sunfish (L. microlophus) abundance was significantly higher on reef areas as compared to between-reef areas, or control areas. A creel survey measured improved catch rates for largemouth bass and lower catch rates for sunfish on reef areas. Steven A. Marshall, D. J. Renfro

Estimating the Effects of a North Florida Reservoir Drawdown Utilizing Creel Data Lake Talquin was dewatered in September 1983 and a 2-stage refill was completed by mid-July 1984. Spring creel surveys were conducted by the Florida Game and Fresh Water Fish Commission prior to (1978, 1981) and following (1985-88) this drawdown. Harvest estimates have increased 5-fold for largemouth bass (Micropterus salmoides) since 1986. Black crappie (Pomoxis nigromoculatus) were harvested in record numbers in 1987 but declined appreciably in 1988. Sunfish harvest after 1986 returned to pre-1986 levels and has stabilized.

Mortality of White Crappie After Catch and Release We conducted tests to quantify delayed mortality of white crappie (Pomoxis annularis) after catch and release by anglers. White crappie were subjected to I) catch and release in shallow water using traditional hook-and-line methods and 2) rapid depressurization to simulate catch in deep water. Mortality 6-11 days after catch and release from shallow water averaged 3%. No significant differences (P > 0.05) were detected between mortality rates of white crappie 15-25 cm and >25 cm total length, nor between fish caught using live and artificial baits.

Multiple Survey Evaluation of a Kentucky Commercial Trotline Fishery The commercial trotline fishery on the Kentucky portions of Kentucky Lake and Lake Barkley was evaluated by a telephone survey, an onboard survey, and from market data. Results indicate that the telephone survey was a reliable source of economic information based on high correlations (r ≥ 0.89) of effort and harvest data among the 3 data sets. Data obtained from the onboard survey overestimated economic impact of the fishery because of bias toward full-time fishermen. However, the onboard survey did yield accurate species composition information. Russell J. Johnson, T. J. Timmons

Aerial Surveys of Texas Commercial Fishing Vessels Low altitude aerial surveys were conducted at approximately monthly intervals from I April 1987 to 31 March 1988 to determine temporal and geographic distribution of commercial fishing in Texas bay and Gulf (Texas Territorial Sea) areas. Observers counted a total of 4,841 bay commercial vessels and 1,906 Gulf commercial vessels conducting 7 types of fishing activities over the 12-month study period. Commercial shrimping made up 87.7% of all commercial activity. Most activity was observed between May and November.

Estimating Annual Game Fish Bycatch in Commercial Fishing Devices from Harvest Data A major concern in managing commercial fisheries is the potential effect on game fish populations. The objective of this study was to design a model to determine annual game fish bycatch in hoop nets, wire traps, and pound nets utilized in the 51. Johns River, Florida, commercial catfish fishery. Annual bycatch was estimated with a model based on previous estimates of annual catfish harvest, catfish-to-game fish ratios, mean weight of catfish harvested and percentage composition of catfish harvested by each gear type.

Overwintering of South Carolina and Texas Stocks of Fingerling Red Drum South Carolina and Texas red drum (Sciaenops ocellatus) fingerlings were compared to evaluate pond overwintering characteristics. Red drum from each hatchery stock were spawned in September 1987 and fry were reared in outdoor earthen ponds. Red drum fingerlings (mean ± SD total length (TL) South Carolina fish 50.5 ± 4.9 mm; Texas fish 48.3 ± 4.4 mm) were transferred to 6 0.2-ha saltwater ponds in November 1987, and ponds were harvested in March 1988. The lowest water temperature encountered was 3.00 C on 10 January 1988.

Supplemental Feeding of Hybrid Striped Bass Fry Phase-l hybrid striped bass fry were fed trout pellets at 0,6.7, and 13.4 kg/haJday, in 7 culture ponds in 1986. Yield ranged from 45.6 to 239.7 kg/ha. Survival ranged from 11% to 70%. Five ponds in which fish were fed trout pellets had substantially greater yields of hybrid striped bass fingerlings than 1 pond in which fish were unfed. In 1987, two culture ponds in which fish were fed trout pellets at 13.4 kg/haJday from the time of initial stocking had significantly greater (P < 0.05) yields of hybrid striped bass fry than 2 ponds initially fed 18 days after stocking.

Growth of Hybrids of Striped Bass x White Bass Fed Redbelly Tilapia or Trout Pellets The growth in weight of hybrids of striped bass (Morone saxatilis x white bass M. chrysops) fed trout pellets was compared to that of hybrids fed redbelly tilapia (Tilapia zilli, the latter of which were starved to reduce lipid content or were well-fed to ensure greater lipid levels. Production did not differ significantly between fish that ate starved tilapia and those that ate trout pellets. Growth was significantly greater, however, in hybrids that ate fed tilapia than in those that ate starved tilapia. Jonathan Chervinski, N. C. Parker, G. T. Klar

Influence of Daphnia Density on Survival and Growth of Paddlefish Larvae at Two Temperatures Paddlefish (Polyodon spathula) larvae were fed live cultured Daphnia at 4 densities to determine if larval survival and growth were affected by Daphnia densities at low (ambient) (15.0° ± 1.5° C) and high (21.1° ± 0.5° C) temperatures. Survival of larvae increased with increasing densities of Daphnia in both experiments. Survival was higher in the low-temperature experiment than in the high-temperature experiment. However, larval survival was also influenced by cannibalism and a deformity affecting swimming behavior. Steven D. Mims, H. R. Schmittou

Catfish Movement and Habitat Use in a Missouri River Tributary Adult channel catfish (Ictalurus punctatus) and flathead catfish (Pylodictis olivaris) monitored by radiotelemetry made frequent movements within Perche Creek, a tributary of the lower Missouri River. Individuals of both species moved at a rate greater than 50 m/day in >50% of all observations. The favored depth for both species was 1 - 2 m, even though shallower and deeper habitats were available. Both species avoided open water habitat and selected complex woody structure over other cover types.

Sampling Flathead Catfish in Small Streams Small diameter hoop nets were compared with low frequency, pulsed DC electrofishing for assessing flathead catfish (Pylodictis olivaris) stocks in the Noxubee River, a small stream in east-central Mississippi. Small diameter hoop nets fished during summer low flow regimes were appropriate for collecting stock size fish (≥280 mm, total length) while electrofishing was a better tool for assessing smaller flathead catfish. No significant difference (P >0.05) was found between the 2 sample techniques with regard to kg/man-day or fish/man-day. Enrique E. Pugibet, D. C. Jackson
