Clearly there is a recognized need for leadership in conservation. One of the great challenges facing our professional agencies and conservation groups is to decide who comprises the constituency we seek to lead. In short, what is our constituency? In many jurisdictions only a fraction of the public is even aware that a specific state agency for wildlife conservation exists. Even a large majority of hunters, long recognized as perhaps the constituency, do not look to professional agencies for leadership . . . at least not with respect to issues dealing specifically with hunting.

The Effect of Habitat Patch Size on Small Mammal Populations Habitat fragmentation is one of the greatest threats to the conservation of biodiversity and has 3 components: habitat loss, patch isolation, and patch size. We tested the effects of forest-clearing size on small mammal populations in the Upper Coastal Plain of South Carolina. These clearings act as islands for many species of small mammals, particularly old-field mice (Peromyscus polionotus) and cotton rats (Sigmodon hispidus). Mark D.Yates, Susan C. Loeb, David C. Guynn, Jr.

The Role of the Media in Promoting the Angling Experience Angling media outlets join fishery management agencies, tourism promoters, and the fishing tackle industry in having a vested interest in maintaining or increasing angling participation. Media outlets, including print, television, videotape, radio, and the Internet, need an audience to buy their services, and the market is increasingly competitive.

Trophic Dynamics of Juvenile Largemouth Bass in Lucchetti Reservoir, Puerto Rico The feeding dynamics of juvenile largemouth bass (Micropterus salmoides) were studied from March 1992 to December 1994 in Lucchetti Reservoir, Puerto Rico. Early piscivory by juvenile bass was aided by constant, but qualitatively variable, availability of fish prey items including threadfin shad (Dorosoma petenense), mozambique tilapia (Tilapia mossambica), redbreast tilapia (T. rendalli), and bluegills (Lepomis macrochirus). Threadfin shad was the primary food item for juvenile bass, supplemented by bluegills and tilapias when abundant. Alexis R. Alicea, Richard L. Noble, Timothy N. Churchill

Utility of National Wetlands Inventory Data for Black Bear Habitat Assessment in Coastal Louisiana Existing landcover maps offer an inexpensive opportunity to conduct largescale habitat assessments for black bears (Ursus americanus), but because cover classes used in these maps may have been developed without consideration for bears, inferring bear food and cover distribution from these maps may be difficult. We evaluated the information content of a habitat map that we constructed using National Wetlands Inventory (NWI) data for a composite home range of 21 radio-tagged adult black bears in coastal Louisiana.

Validation of the Great Blue Heron HSI Model Reproductive Index for the Southcentral Great Plains We field-tested the Reproductive Index (RI) of the great blue heron (Ardea herodias) Habitat Suitability Index (HSI) model in the southcentral Great Plains with the aid of Geographic Information System (GIS) technology. From January 1993 through May 1994, populations of great blue herons in 18 rookeries located throughout Oklahoma were monitored, and GIS was used to evaluate data on rookery habitat structure and surrounding landscape features. Eighteen rookeries were classified as potential nest sites and RI ratings were determined for each rookery according to model criteria. Bruce A. Corley, William L. Fisher, David ML Leslie, Jr

We describe a new, non-destructive procedure for visually estimating forage biomass based on volumetric cover. The accuracy of this procedure was tested against actual dry biomass by clipping and weighing 41 plots of wax myrtle (Myrica cerifera). Visual estimates of forage biomass were significantly related (P ≤ 0.001) to actual biomass determine by clipping (r2 = 0.925; y = 16.36 + 2.52 X, where y = dry biomass and X = volumetric cover). We developed this procedure to apply 3 white-tailed deer (Odocoileus virginianus) habitat suitability index (HSI) models to a suburban development. Joe N. Caudell, Robert J. Warren

What Will We Do?—Inside the Mind of Unfished Harry and Mary Although fishing has been around for thousands of years, many people in today's civilized world have little concept of how or why to fish. For those of us in the industry, finding ways to answer the most basic questions about fishing and reduce or remove barriers to fishing has long since eluded us. Why go fishing? What makes fishing fun? Is fishing safe? How do I fish? Where do I fish? How much does it cost? What do I do with the fish when I catch it?

Wildlife Agencies Perspectives of Conservation Leadership The development of the conservation movement in the United States and particularly the role of the state fish and wildlife agencies is one of the greatest conservation statements in world history. During the 20th century, our leaders have shown great foresight and vision in stewarding our country's fish and wildlife resources. It would be easy to say we are solid, we have the track record to prove our mettle—to accept the "do nothing alternative"—the business-as-usual approach. It is, ironically, our stellar record that today may be our biggest liability.

Marketing as a Management Tool at the Florida Game and Fresh Water Fish Commission Faced with declines in participation and license revenue, combined with increasing difficulty in securing general revenue funds, the Florida Game and Fresh Water Fish Commission leadership concluded that changes in the way the entire agency conducted itself appeared to be the only long term solution to the problem. Marketing principles were instituted agency-wide as a primary management tool. Marketing at the Commission would be a function everyone participated in, not just a promotional department.

We conducted an operational scale trial of the herbicides Sonar® (fluridone) and Rodeo® (glyphosate) to evaluate control of giant cutgrass (Zizaniopsis miliaceae) and effects on waterfowl food plants in moist-soil managed impoundments of the Altamaha Waterfowl Management Area, Darien, Georgia. Sonar and Rodeo reduced giant cutgrass frequencies both post-treatment years, although greater reduction occurred in the Rodeo-treated impoundment. Panic grass (Panicum spp.) frequency within the Rodeo- treated impoundment decreased the first year post-treatment. Donald E. Wood, K. V. Miller, D. L. Forster

Fish and Wildlife Law Enforcement Man Tracking Awareness Fish and wildlife officers are trained in most aspects of law enforcement, arrest, search and seizure, all types of criminal investigations, fish and wildlife identification, firearms, drugs, interrogation, driving, and so on, but fewer may be trained in something they do just about every day and which could be life saving: tracking.

Field Trials to Determine the Efficacy of Human Chorionic Gonadotropin for Spawning Walleye Human chorionic gonadotropin (HCG) is often used to induce spawning of fish. However, the U.S. Food and Drug Administration (FDA) has not approved HCG for use in fish because they claim additional efficacy data are required. Efficacy of HCG for spawning walleye (Stizostedion vitreum), was evaluated at 3 hatcheries for 3 years. During the 1993-1995 spawning seasons, 17.5% (54 of 308) of female walleyes spawned after a single injection of HCG. Of 253 females receiving a second injection, 92.1 % spawned for an overall spawning success of 93.2%.

Factors Determining Quality of Oxytetracycline Marks in Fingerling Walleye Otoliths This study examined factors which can affect the quality of fluorescent oxytetracycline (OTC) marks on walleye (Stizostedion vitreum) otoliths. A 1 -time exposure to a strong ultraviolet (UV) light source, such as is done when viewing under a UV microscope, significantly decreased mean OTC mark qualities from an initial value of 2.8 (3.0 is maximum and 0.0 is no mark) to <1.0 3 months following the initial examination. Mark intensity continued to decrease over time (<0.5 after 6 months, 0.3 after 12 months). Donald R. Harrison, r. C. Heidinger

Evaluation of Wild Turkey Trapping Techniques in West Virginia We studied efficiency of the rocket, rocket box, and cannon-net trapping techniques and the effects of the techniques on the physical condition of eastern wild turkeys (Meleagris gallopavo silvestris). We trapped 1,168 wild turkeys during a 5-year period (1989-1994). There were no differences in trapping efficiency (P > 0.05) among techniques. Fall (Sep-Oct) and winter (Jan-Apr) trapping efficiencies were not different (P > 0.05). Trappers with ≥1 year of experience had higher trapping efficiency (P < 0.0002) than trappers with no prior experience. James C. Pack, C. I. Taylor, D. A. Swanson, S. A. Warner

We used mark-resight methods to estimate sighting proportions of American alligators (Alligator mississippiensis) during night-light and aerial helicopter surveys. Alligators ≥122 cm were captured during 5- to 12-day periods on Orange Lake and Lake Woodruff National Wildlife Refuge, Florida, and marked with paint on the dorsal neck area. Replicate helicopter surveys were subsequently flown on each area to record marked and unmarked individuals. Population estimates were calculated and compared with night-light and aerial counts of alligators ≥122 cm. Allan R. Woodward, K. G. Rice, S. B. Linda

Electrofishing Catch of Largemouth Bass: Spatiotemporal Variation and Relation to Angler Catch I examined spring and fall electrofishing catch rates of largemouth bass (Micropterus salmoides) in 12 Texas reservoirs from 1986 to 1992 to assess the relative importance of spatial and temporal variation and to evaluate the relation between electrofishing catch rates and future angler catch. East Texas reservoirs were characterized by relatively greater temporal (i.e., annual) variation in electrofishing catch rates, whereas west Texas reservoirs tended to exhibit greater spatial variation. Reservoirs in east Texas shared a common temporal pattern in electrofishing catch rates.

Effects of Winter Capture on Wild Turkey Hen Movement in Mississippi Analyses of movement patterns of free-ranging animals derived via radiotelemetry assumes that capture has no effect on the parameters of interest. To mitigate against potential biases, many researchers will censor locational data for an arbitrary post-capture duration (e.g., 2 weeks). To investigate validity of this assumption, we compared home range size, average inter-location distance, dispersion, and total distance moved between hens captured in a given interval to those captured in previous intervals. Data were from winter-captured hens in Kemper County, Mississippi, 1986-1992. Mike Weinstein, G. A. Hurst, B. D. Leopold

Effects of Raccoon Hunting on White-tailed Deer Movement and Harvest Potential The impact of raccoon (Procyon lotor) hunting with trained hounds on movement, daily use area, and harvest potential of white-tailed deer (Odocoileus virginianus) was studied on Westvaco Corporation's North Whitener Tract in Jasper County, South Carolina, in winter 1993-94 and 1994-95. Two groups (treatment and control) of radioinstrumented deer were selected from a larger group of radio-collared deer. James D. Westerhold, T. T. Fendley, O. E. Baker, III

Effects of Planting Date and Nitrogen Fertilization Rate on Selected White-tailed Deer Forages We studied the effects of 3 planting dates (Sep, Oct, Nov) and 2 fertilization rates (the recommended nitrogen [N], phosphorus [P], and potassium [K] based on soil testing and twice the recommended N, with P and K) on rye (Secale cereale), oats (Avena sativa), and wheat (Triticum aestivum) planted for white-tailed deer {Odocoileus virginianus) from 1991 to 1993. Forage plantings established early (September) in the cool season produced the most forage during the season and maximized production during hunting season. John W. Bowers, N. A. Waer, H. L.

Effects of Early-Weaning on Captive White-tailed Deer Fawns The welfare of white-tailed deer (Odocoileus virginianus) fawns orphaned during an early doe harvest is of management interest when the hunting and fawning seasons are temporally close. A 2-year study on early-weaned, captive white-tailed deer fawns was conducted to evaluate potential effects of early orphaning on growth and survival. Comparisons were made between survival of 60-day-old weaned fawns (TV = 28), 90-day-old weaned fawns (N = 21), and control fawns left with their does (N = 21). Jacob L. Bowman, H. A. Jacobson

Effects of Early Weaning on Survival and Growth of Captive White-tailed Deer Thirty-seven white-tailed deer fawns (Odocoileus virginianus) born during summer and autumn 1993 were used to study effects of early weaning on survival and growth. Fawns at birth (date recorded) were weighed (kg), measured (cm), and tagged for identification. Fawns were randomly assigned to early weaned (treatment) or control groups at 60 days of age. Treatment animals were separated from their dams at this time, and control animals remained with their dams until 6 months of age. Both groups were fed a pelleted ration containing a medium protein level (11.6%). David F. Carroll, M. K. Causey

Effectiveness of Flying Squirrel Excluder Devices on Red-cockaded Woodpecker Cavities I tested the effectiveness of squirrel excluder devices (SQEDs) in deterring southern flying squirrels (Glaucomys volans) from using artificial red-cockaded woodpecker {Picoides borealis) cavities by placing them on approximately one-half of the cavities in 14 inactive recruitment clusters on the Savannah River Site, South Carolina. SQEDs consisted of 2 pieces of 35.5-cm wide aluminum flashing placed 7.6 cm above and below the cavity entrance.

Effectiveness of an Electrical Barrier in Blocking Fish Movement Electrical barriers were successful in blocking movements of gizzard shad (Dorosoma cepedianum), golden shiners (Notemigonus crysoleucas), rainbow trout (Oncorhynchus mykiss), brown trout (Salmo trutta), and largemouth bass (Micropertus salmoides) stocked in a 24-m long canal during simulated modes of pumped hydropower operation. Blockage rates were highest during nongeneration (95%-97%) and generation (94%-97%), and lowest during pumping (83%-84%).

Ecology of Flatwoods Salamander Larvae in Breeding Ponds in Apalachicola National Forest Management of the flatwoods salamander (Ambystoma cingulatum), a species in decline throughout its range, is hindered by a lack of information on the habitat requirements of the species. Because Ambystomatids are generally philopatric, preservation of quality natal habitat is important for long-term population health and stability. Conservation of breeding sites in managed landscapes is impeded by insufficient knowledge of the habitat components required for successful larval development. Carolyn M. Sekerak, G. W. Tanner, J. G.

Distribution and Population Attributes of Gulf Sturgeon in the Lower Pearl River System, Louisiana Seven reaches of the lower Pearl River system were sampled with bottom set gill nets from 1992 through 1995. One hundred fifty-eight Gulf sturgeon (Acipenser oxyrinchus desotoi) were captured in 3 reaches. Mean fork length (FL) was 734 mm, and weight (W, g) to length (FL, mm) relation was: W = 1.786 x lO^CFL)3204. Mean weight loss during summer was 1.9 g/day. Ninety-two percent of Gulf sturgeon were captured in the West Middle River reach which is comprised of deep holes and little current. James V. Morrow, Jr., K. J. Killgore, J. P. Kirk, H. E. Rogillio

Distribution and Habitat Indices of Northern Pine Snakes in North Carolina A survey of northern pine snake occurrences (Pituophis m. melanoleucus) was completed in North Carolina in 1990 to determine the distribution and habitat of this state-listed species of special concern. A total of 196 snakes at 163 locations was mapped and visited. Most of the snakes were killed by vehicular traffic. Sixteen pine snakes were recorded at 12 sites in 3 mountain counties, a single snake from each of 2 sites in 1 foothill county, and 26 snakes at 24 sites in 2 coastal counties. David K. Woodward, G.

Stomachs of 5,818 largemouth bass (Micropterus salmoides) were examined from 10 north-central Florida lakes to determine differences in food habits of largemouth bass in lakes with abundant aquatic macrophytes (vegetated) and lakes nearly devoid of aquatic macrophytes (unvegetated). We found significant differences (P < 0.05) between stomach contents of 6 length groups of largemouth bass (range: 60-640 mm TL) from vegetated and unvegetated lakes. The 152- to 254-mm length group exhibited the greatest number of diet differences. Richard L. Cailteux, W. F. Porak, S. Crawford, L. L. Connor

Diets and Factors Affecting Feeding Success of Age-0 Gizzard Shad Diets, food selection, and factors affecting feeding success of small (5-9 mm total length, TL), medium (10-19 mm TL), and large (20-29 mm TL) larval and early juvenile gizzard shad (Dorosoma cepedianum) were examined in 2 large Missouri reservoirs. Diets and food selection shifted from mainly copepod nauplii and cyclopoids to rotifers and phytoplankton as fish grew. Mean length of ingested zooplankton rose slightly as gizzard shad grew from the small to medium length groups and then decreased for the large length group.

Aviation Uses in Wildlife Agencies and How to Get Started Over the past decade, Florida has undergone rapid suburbanization of its borderline wilderness areas. New airspace restrictions and low-level flight restriction over what are now populated areas have increasingly impeded aerial wildlife research and law enforcement patrol with fixed-winged aircraft. During the same decade, domestic marijuana cultivation in Florida's wilderness areas, especially Commission-maintained wildlife management areas, has increased dramatically.

Use of a Nursery Pond to Establish Smallmouth Bass in Beaver Reservoir, Arkansas Production of smallmouth bass (Micropterus dolomieu) in 11 -ha Beaver Nursery Pond was estimated from 1990 to 1994 to determine numbers of fish stocked in Beaver Reservoir. In 1990, 2 rapid population sampling methods, seining a known area and SCUBA transects, were tested against a Petersen mark-and-recapture estimate. Both sampling methods provided population estimates that did not differ significantly from mark-and-recapture values, but both generated greater confidence intervals. James E. Johnson, M. G.

Activity Patterns of Dabbling Ducks Wintering in Coastal South Carolina Nearctic dabbling ducks (Anatini) use varied wintering habitats. Spatial and structural variability among these may translate into differing capabilities of habitats to meet behavioral and physiological requirements of ducks. Our study was conducted on the Santee River Delta (SRD) in South Carolina, an important wintering area for dabbling ducks in the Atlantic Flyway. Brian T. Gray, D. H. Gordon, R. M. Kaminski

Age and Growth of Trophy Largemouth Bass in Florida Otoliths from 822 trophy (>4.5 kg) largemouth bass (Micropterus salmoides) caught by anglers in Florida were obtained from taxidermists during 1987-1993. The fish were harvested from 211 different water bodies. Longevity and mean growth exceeded those reported previously in Florida. Mean age of trophy largemouth bass statewide was 9.7 years and ranged from 4.0 to 16.5 years. Mean growth averaged 0.54 kg/year with a range of 0.28-1.27 kg/year. Growth rate of trophy largemouth bass increased from north to south Florida. Steve Crawford, W. F. Porak, D. J. Renfro, R. L. Cailteux

Alligator Nest Temperatures and Hatchling Sex Ratios in Coastal South Carolina The relation between natural nest temperatures and hatchling sex ratios of American alligator (Alligator mississippiensis) has not been determined adequately. The few studies to date have been limited by study design, low sample size, and inadequate equipment. We investigated this relationship in 20 nests in impoundment habitat in South Carolina during 1995. Actual sex ratios were highly correlated (r = 0.971, P < 0.001) with sex ratios predicted from laboratory results, on the basis of mean nest temperatures between days 30-45 of incubation (temperature-sensitive period (TSP)).

A Comparison of Snap Traps for Evaluating Small Mammal Populations We compared rat, mouse, and museum special snap traps to determine if differences existed in capture efficiency of small mammals and whether type of trap affected indices of richness, evenness, and diversity. Small mammals were trapped in 57 streamside study areas in 1990 to 1995 in the Ouachita Mountains, Arkansas. Efficiency of mouse traps was equal to or greater than that of museum special traps in capturing all small mammal species. Roger W. Perry, P. A. Tappe, D. G. Peitz, R. E. Thill, M. A. Melchoirs, T.

Expansion of the black bear (Ursus americanus) population outside White River National Wildlife Refuge, Arkansas, has caused local citizens to request reduction of the population. An estimate of black bear population size is necessary before any management recommendations can be made. We used 2 census methods to estimate population size. Hunter surveys of bear sightings during the 2-day firearm deer hunt were used in 1994 to estimate population size with a Petersen-Lincoln estimator. The survey yielded a population estimate of 213 bears (95% CI = 129-297). Jacob L. Bowman, M. J. Chanberlain, B. D. Leopold, H. A. Jacobson

Annual Cycles of Growth and Use of Chinese Privet by White-tailed Deer in Northwestern Georgia Chinese privet (Ligustrum sinense) is a common shrub in the southeastern United States, but no studies have examined white-tailed deer (Odocoileus virginianus) use of privet. We investigated the seasonality of deer use of privet browse and the effect of deer browsing on privet twig growth. We tagged and repeatedly measured about 200 privet twig clusters in forest and field-edge habitats at Chickamauga Battlefield Park (CBP) in northwestern Georgia during 2 consecutive years. Karl A. K.

Attitudes of Wild Turkey Hunters Toward Potential Regulation Changes in Mississippi Numbers of wild turkeys (Meleagris gallopavo) and turkey hunters have increased greatly in the Southeast during the last 3 decades, and administrators and managers should be aware of hunter attitudes toward potential hunting regulation changes. Our objective was to determine attitudes of turkey hunters regarding regulations on use of hunter orange, baiting, and a fall either-sex harvest. We conducted a mail survey of turkey hunters (N = 4,026) who hunted turkeys in Mississippi during the 1994 spring gobblers-only season. John T. Forbes, K. D. Godwin, G. A. Hurst

Deer Harvest Characteristics During Compound and Traditional Archery Hunts Resource managers require accurate estimates of hunter success rates with various weapon types to predict annual harvests and design management strategies. We obtained harvest data for white-tailed deer (Odocoileus virginianus) on the McAlester Army Ammunition Plant in southeastern Oklahoma during periods of compound (1983— 1988) and traditional archery (1989-1995) hunting to compare hunter success rates and the sex and ages of deer harvested. Hunter success was greater (P = 0.001) with compound (¯x = 17.8%; SE = 1.3) than traditional archery equipment (¯x = 10.7%; SE = 0.9). Stephen S. Ditchkoff, E. R. Welch,Jr., R. L. Lochmiller, R. E.

Deer Forage in Hardwood Stands following Thinning and Fertilization We conducted a 10-year study in oak-hickory stands in the Arkansas Ozarks to investigate the effects of intermediate thinning and nitrogen (N) fertilization on the annual production of understory vegetation. A total of 101 experimental plots was thinned to residual overstory densities of 40%, 60%, 80%, or 100% of full stocking. Nitrogen fertilizer (336 kg N/ha) was applied to a subset of plots in each thinning treatment. Understory species composition and biomass were estimated 1, 2, 3, 5, and 10 years after treatment.

Contribution of Largemouth Bass Reared in Nursery Ponds to Year Classes in Two Texas Reservoirs Genetically-marked Florida largemouth bass (Micropterus salmoides floridanus) fingerlings with rare or unique genotypes were stocked into nursery ponds at Lake Conroe (8,484 ha) and Lake Gladewater (323 ha). Following grow-out, advancedsize individuals were stocked into respective reservoirs. We measured the contribution of stocked individuals to corresponding year classes in receiving reservoirs. Largemouth bass survival in nursery ponds at the end of the grow-out period was 15.6% at Lake Conroe and 20.9% at Lake Gladewater. Michael J. Ryan, M. A. Webb, L. T.. Fries

Characteristics and Use of Cavity Trees and Snags in Hardwood Stands A 3-year study was conducted to evaluate the availability and use of cavity trees and snags in hardwood stands regenerated using the group selection method. A survey of cavity trees and snags was completed before and after group selection harvest in 16 2.9-ha plots in the Ozark National Forest, Arkansas. Cavity trees and snags were identified to species, and the height, dbh, state of decay, and number of visible cavities recorded. We marked and measured 66 cavity trees and 126 snags with cavities, and observed the use of these cavities by wildlife. Thomas A. Nelson, M. L. Lambert

Bobcat Habitat Use at Multiple Spatial Scales Habitat use occurs at several spatial scales; however, bobcat (Felis rufus) habitat use has not been investigated at multiple scales. Additionally, sex-specific differences in bobcat habitat use have been hypothesized but not tested. Therefore, we investigated habitat use of 30 bobcats (9 males, 21 females) from 1 January 1989 to 31 December 1993 on 2 study areas in east-central Mississippi. We investigated bobcat habitat use at 2 spatial scales: habitat use within the home range and habitat composition of the home range relative to habitat composition of the study area.

Diet and Movement of Largemouth Bass and Butterfly Peacocks in La Plata Reservoir, Puerto Rico Diet and telemetry studies were conducted in La Plata Reservoir, Puerto Rico, to investigate potential interactions between largemouth bass (Micropterus salmoides) and butterfly peacocks {Cichla ocellaris). Partitioning of food resources between the 2 species was evident and consistent over several size classes. Interspecific differences were observed in home range size, diel movement, and habitat preference during telemetry studies conducted on adults for up to 250 days. Maximum activity for both species corresponded with periods of elevated food consumption. Craig G. Lilyestrom, T. N. Churchill
