Armadillo Diets Among Seasons and Between Habitats on Cumberland Island, Georgia In the 1970s, the nine-banded armadillo (Dasypus novemcinctus) invaded Cumberland Island, Georgia, which includes a federally designated wilderness area where native flora and fauna are protected by the National Park Service. Because of concerns about the potential ecological effects of this exotic mammal on the island's protected ecosystems, we collected 171 armadillos to determine their diets by stomach content analysis. We measured relative amounts of each food on a seasonal basis for a sub-sample of armadillos from oak-palmetto (N=44) versus oak-pine (N=43) habitats. David A. Osborn, Martin I. Nelson, Robert J.

Habitat Use and Productivity of Mottled Ducks on the Atchafalaya River Delta, Louisiana We studied nesting habitat selection, nest density, and nest success of mottled ducks (Anas fulvigula) on islands in the Atchafalaya River Delta, Louisiana, 1995-1996. Nesting mottled ducks preferred shrub-moderate habitats and avoided shrub-sparse and marsh habitats. Other habitats were neither preferred nor avoided. Nest densities using non-random plot sampling in 1995 and line-transect sampling in 1996 averaged 3.9 nests/ha and 1.3 nest/ha, respectively. Mayfield nest success estimates on individual islands ranged from 6.0% to 67.1%. Robert S. Holbrook, Frank C. Rohwer, William P. Johnson

We radiotracked 6 eastern red (Lasiurus borealis), 6 Seminole (Lasiurus seminolus), and 24 evening bats (Nycticeius humeralis) to 55, 65, and 61 day-roosts, respectively, during summers 1996 and 1997 in the Upper Coastal Plain of South Carolina. For each species, we tested for differences between used roost trees and randomly located trees. We also tested for differences between habitat characteristics surrounding roost trees and randomly located trees. M. Alex Menzel, Timothy C. Carter, W. Mark Ford, Brian R. Chapman, James Ozier

Estimating Sighting Proportions of American Alligator Nests during Helicopter Survey Proportions of American alligator (Alligator mississippiensis) nests sighted during aerial survey in Florida were estimated based upon multiple surveys by different observers. We compared sighting proportions across habitats, nesting seasons, and observer experience levels. The mean sighting proportion across all habitats and years was 0.736 (SE=0.024). Survey counts corrected by the mean sighting proportion reliably predicted total nest counts (7?2=0.933). Sighting proportions did not differ by habitat type (P=0.668) or year P=0.328). Kenneth G. Rice, H. Franklin Percival, Allan R. Woodward

Hunter Opinions Regarding Mourning Dove Management on Alabama Public Lands The importance of public lands for mourning dove (Zenaida macroura) hunting in the Southeast may increase as other dove hunting opportunities decrease. Maximimizing satisfaction of dove hunters on public lands requires knowledge concerning hunter opinions and preferences. We documented dove hunter satisfaction on state Wildlife Management Areas (WMAs) in Alabama with respect to habitat and hunter management. Crops planted were the primary management concern; hunters preferred corn and browntop millet for dove hunting. Steven E. Hayslette, James B. Armstrong, Ralph E. Mirarchi

Delineating Age and Species of Harvested Cottontail and Swamp Rabbits Age structure of harvested populations is important to wildlife biologists to adequately observe effects of harvest and management regimes. We aged harvested cottontail (Sylvilagus floridanus) and swamp (S. aquaticus) rabbits by eye lens weight. We developed 2 logistic regression equations based on external morphometrics (mass [N=213] and hind foot length [N=209]) to predict age and species. Our model used to delineate species had high correct classification rates (>89%). Bobby T. Bond, Jacob L. Bowman, Bruce D. Leopold, L. Wes Burger, Jr., K. David Godwin

Determining the Size of American Alligators Using Hind-foot Track Length Size distribution information is useful for crocodilian management, but can be hard to obtain. Indirect and less costly demographic inferences made from track measurements may be valuable for management decisions. We related hind-foot lengths (HF) with total length (TL) to determine if we could indirectly assess alligator size using track length. Regression showed that HF was an excellent predictor (F1,246= 15722.9, R2=0.98, P<0.01) of TL and track length was an exceptional predictor of HF (F1,14=7520.3, R2= 1.00, P<0.01). Philip M.

Survival and Cause-specific Mortality of Raccoons on a Northern Bobwhite Management Area We estimated survival and cause-specific mortality of 59 raccoons (Procyon lotor) on a wildlife area in Mississippi which was in the early stages of an intensive land management program to enhance northern bobwhite (Colinus virginianus) habitat quality and populations. Average annual survival of radio-collared raccoons was 0.81 for males (N=47) and 0.79 for females (N=12) from March 1997 to February 1999. We detected no effect of sex, season, year, or age (P≥0.05) on survival. Chrissie M. Henner, L. Wesley Burger, Jr., Bruce D. Leopold

We estimated survival rates and cause-specific mortality of radio-marked game farm (N=120), F1-wild progeny (N=120), and wild-relocated northern bobwhites (Colinus virginianus) (N=80) released on the Amelia Wildlife Management Area (WMA) during October 1998 and March 1999 using the Anchor Covey Release System™ (ACRS) and a habitat release system. Mortality of game farm and F1 bobwhites was high immediately following both releases. During fall, game farm bobwhites survived an average of 1.6 ± 0.2 days and Fl-wild progeny survived 3.3 ± 0.8 days. Michael L. Fies, Jason E. Fischer, David E. Steffen

Sources and Patterns of Black Bear Mortality in Louisiana Louisiana black bears (Ursus americanus luteolus) are protected under the Endangered Species Act and live in 3 isolated geographic areas thought to encompass nearly all breeding individuals for that subspecies. Management strategies to recover these bears continue to evolve without knowledge of any differences in demographic patterns among these populations. We summarized data on Louisiana black bear deaths to see if any evidence existed for differences in mortality patterns among the 3 subpopulations. Richard M. Pace, III, Donald R. Anderson, Steve Shively

Survival and Reproduction of Wild Turkey Broodstock Relocated to the Pineywoods of East Texas We assessed survival and reproduction of Georgia and Iowa eastern wild turkeys (Meleagris gallopavo silvestris) relocated to the Pineywoods of Texas. Using approximately equal numbers from each state, 12 females and 3 males were radio tagged and released at each of 4 sites in February 1994. In February 1995, 8 resident females were captured, radio tagged, and released on a disjunct study area intensively managed for wildlife. Radio tracking of the turkeys began immediately after release and continued until 30 June 1996. James R. George, R. Montague Whiting, Jr., John D. Burk

Survival and Reproductive Biology of the Bachman's Sparrow We estimated breeding season survival rates and nest success for Bachman's Sparrows at the Savannah River Site, South Carolina, using radio telemetry. The 1995 breeding season (2 May-9 Aug) survival rate was 0.905 (95% C. I. 0.779-1.03) with 2 mortalities out of 20 individuals. The 1996 breeding season (10 May-25 Jul) survival rate was 0.882 (95% C. I. 0.729-1.04) with 2 mortalities out of 18 individuals. No significant differences in survival rates were detected between years, sexes, or habitat types. The overall breeding season survival rate was 0.893 (95% C. I. 0.794-0.992). Jonathan M.

Space Use and Movements of Raccoons in Two Forested Ecosystems Raccoons (Procyon lotor) are important furbearers that generate considerable income and recreation across the southeastern United States. Growing concerns about impacts of raccoons on wildlife populations necessitates sound information on raccoon behavior and population dynamics. Forest management has changed throughout the southeastern United States due to increased demands for wood fiber and changing land-use objectives on public lands. Michael J. Chamberlain, Bruce D. Leopold, Kurt M. Hodges, Jason E. G. Burton

Home Range Sizes of Fox Squirrels in Southwest Georgia Home range size quantifies space needed by an animal in a given area and time. Because fox squirrel (Sciurus niger) home range estimates in the Southeast are rare, I radio-monitored fox squirrels to determine their seasonal and composite (i.e., total duration of monitoring) home range size in southwest Georgia between March 1998 and September 1999. There was no sex by season interaction (P =0.11). Male seasonal and composite home ranges (35.8±4.4 ha and 37.0±3.6 ha, respectively) were larger (P <0.001) than female home ranges (seasonal = 13.3±1.5 ha, composite =21.0±6.3 ha).

Distribution and Status of the Swamp Rabbit in South Carolina We conducted a survey from 1990 to 1995 to determine the distribution and status of the swamp rabbit (Sylvilagus aquaticus) in South Carolina. Populations appear largely confined to 3 counties in the Savannah river watershed of northwestern South Carolina. We found little evidence that a significant change in distribution has occurred in South Carolina since the species was first reported in the late 1930s. Swamp rabbits are restricted to bottomlands, but were found in a variety of successional habitats ranging from old-fields to mature hardwood forests.

Home Range Dynamics and Den Use of Nine-banded Armadillos on Cumberland Island, Georgia We implanted radio transmitters in 11 armadillos (Dasypus novemcinctus) on Cumberland Island, Georgia, and monitored them seasonally from July 1987 through May 1988. Six individuals survived (S) the entire study: 5 died (D) between 1-4 months post-implantatin. Home range sizes for S individuals did not differ significantly between sexes (N=6; 3 males and 3 females). Bobby T. Bond, Martin I. Nelson, Robert J. Warren

Morphometrics and Movement Patterns of Coyote-like Canids in a Southwest Louisiana Marsh Complex We examined relative body size and space use patterns of free-ranging coyote (Canis latrans)-like canids occupying a marsh complex known to have been one of the last refuges of red wolves (Canis rufus). Morphometric analysis indicated that these animals were larger than other Louisiana coyotes, but smaller than red wolves. We radio-tagged 25 (13 male and 12 female) animals during January-August 1996 and January-April 1997 at Sabine National wildlife Refuge, Cameron Parish, Louisiana. Mark R. Giordano, Richard M.

Prevention and Intervention Strategies for Disgruntled Officers Maintaining a motivated workforce is a challenge for all organizations. Law enforcement agencies are faced with the apparent contradiction in that the factors and performance we value most in officers can utimately lead to them becoming disgruntled and malcontent. Recognition of the early indications of problems is the responsibility of administration, first-line supervision, and the officers themselves. The goal is to guide officers into a well-rounded and balanced life, which will in turn lead them to being productive and motivated for their entire career.

Wildlife Crime Watch a Partnership for Wildlife, the Environment, Property and People Wildlife Crime Watch is a program based on the successful “Neighborhood Watch.” The objective is to develop a close working partnership with citizens within their communities. This program is an agency-wide effort, not just law enforcement, to involve people in the protection and development of wildlife, the environment, property, and people. By utilizing traditional crime prevention strategies/training we attempt to involve individuals within a community who are not normally interested in wildlife and environmental issues.

Game Warden Role and Responsibilities Associated with Metropolitan Areas The need for game warderns in metropolitan areas is greatly underestimated. Demographics are used to show comparisons between tasks performed by wardens in metro vs. rural areas. This is demonstrated by tabulating the activity from wildlife agency reports. Results from Oklahoma hunter participation surveys are used to calculate regional hunting pressure and illustrate the violume of investigations. Wildlife revenue data from 3 county-based license categories are used as relative indices to show sportsmen density.

Law Enforcement Trends Affecting Georgia's Conservation Rangers Conservation Rangers in the Georgia Department of Natural Resources (DNR) face new challenges that have resulted from social and ecological changes caused by urbanization during the past 10-20 years. As the type of natural resource user in Georgia has changed, so has the role and responsibility of the conservation ranger. These changes include increased numbers of boaters, decreased numbers of hunters, an increased emphasis on education of the public by law enforcement personnel, and new laws (some of which are not game and fish laws) to enforce.

Investigation of Migratory Bird Mortality in Arkansas Oil Pits In south Arkansas, the use of open oil pits by the oil industry and the oil, which has escaped into the secondary containment areas, is having a detrimental impact on migratory waterfowl, game species, non-game species, and the surrounding environment. The use of aerial surveillance to visually locate these sites and recording of the sites with a GPS has proven the most effective method for location of problem areas. Kevin A. Wood, Fred W. Harrod, Jr.

Estimating Post-mortem Intervals of Wildlife Carcasses Using Necrophilous Insects The succession and species composition of necrophilous insects on animal carcasses can be used by wildlife law enforcement officers for estimating postmortem interval (PMI) at suspicious death scenes. Necrophilous insects infesting wildlife carcasses (Louisiana black bear, white-tailed deer, and alligator) in a woodland habitat were monitored during the spring of 1999 to eventually develop a guide for estimating PMI by wildlife officers based on an insect database. The study was conducted at the Waddill Outdoor Educational Center in East Baton Rouge Parish, Louisiana. Erin J. Watson, C. Lamar Meek, Brian L. Spillman, Philip E. Bowman

During 1996 and 1997, local wildlife officers reported illegal activity indicating the need for a covert operation to be conducted in and around the Everglades City area of Collier County, Florida. Information indicated individuals in the area were taking large amounts of wildlife and fish including deer, white ibis, snook, and possibly marine sea turtles. As a result, in May 1998, Operation Alliance was born. The operation consisted of 1 covert investigator taking up permanent residence in the Everglades City area.

Intern Programs: A Solution for Wildlife Enforcement Agencies As our nation grows in a successful economy, wildlife enforcement agencies find themselves in a highly competitive race to recruit and develop qualified applicants for the ever-changing career of the wildlife enforcement officer. This challenge is not limited to any one area of the country and solutions must be as innovative as the technological advances our society is experiencing. Agencies that have developed standards for the level of experience and education they require in their officers, must also develop programs that target the recruitment and retention of those officers.

Specialization Units and Natural Resource Law Enforcement Specialization is a needed law enforcement function and strategy to combat white-collar criminal activity involving natural resources. Increased state and federal management concerns of living natrual resources have led to a dramatic increase in law enforcement responsibilities. Effective enforcement of all regulations is integral to the management process to protect, conserve, and maintain sustainable levels of living natural resources. State and federal resource regulations mandate a comprehensive and specialized compliance program.

Food Habits of Flathead Catfish in the Altamaha River System, Georgia The food habits of flathead catfish (Pylodictis olivaris) in the Altamaha River system, Georgia were determined by examining the contents of 866 flathead catfish stomachs from the Altamaha and Ocmulgee rivers during the summer of 1997. Stomach contents were analyzed by frequency of occurrence, percent composition by weight, and percent composition by number. Dominant prey items consumed were centrarchids, ictalurids, and invertebrates. Invertebrates were the most prevalent diet item by number and weight consumed by flathead catfish <30l mm. Robert R. Weller, Craig Robbins

Temperature Selection by Flathead Catfish in a West Texas Reservoir Ultrasonic telemetry was used to determine seasonal temperature selection by adult flathead catfish (Pylodictis olivaris) in a 93-ha reservoir in west Texas, Buffalo Springs Lake. We implanted temperature-sensing ultrasonic transmitters in 29 flathead catfish and monitored them from June 1993 through June 1995. During the summer months, flathead catfish were found in the warmest lake waters (24.5-31.5 C) even though cooler well-oxygenated water was available. As lake temperatures decreased in fall and winter, flathead catfish were located in the warmest available water. Robert R. Weller, Jimmy D. Winter

Food Habits of Bowfin in the Black and Lumber Rivers, North Carolina We examined food habits of bowfin (Amia calva), in the Black and Lumber rivers, North Carolina. Stomachs from 192 Black River bowfin and 175 Lumber River bowfin were analyzed to determine frequency of occurrence and percent by number and weight of individual food items consumed from 1994 to 1997. Crustaceans [primarily crayfish (Astacidae) and grass shrimp (Palaemonidae)] were the dominant food item consumed by bowfin in both rivers. They occurred, on average, in 79% of Black River bowfin stomachs containing food and accounted for 65% by number and 53% by weight of all food items consumed. Keith W. Ashley, Robert T. Rachels

In October 1997, apparent spatial heterogeneity in the black crappie (Pomoxis nigromaculatus) age distribution was observed in B.E. Jordan Reservoir. The number of age groups for black crappie increased from downlake to uplake. The objective of this study was to verify this spatial heterogeneity. Trap nets were used to collect black crappie in 4 sections of the reservoir. Black crappie ages ranged from 1 to 17 years, and fish ≥10 years were found only in the upper 2 sections of the reservoir.

Exploitation of Crappie by Contest Anglers on Lake Texoma, Texas-Oklahoma Contest angler exploitation rates for crappie (Pomoxis spp.) ≥254 mm total length (TL) were estimated for Lake Texoma, Texas-Oklahoma, from tags returned by anglers fishing in Crappiethon USA contests in 1994 and 1995. Unadjusted contest angler exploitation was 27% in 1994 and 23% in 1995. Exploitation rates were adjusted for handling and tagging mortality and tag retention. Non-reporting was assumed to be 0%. Handling and tagging mortality rate estimates were 22% in 1994 and 10% in 1995. Tag loss for both years was calculated at 14%. Bruce T. Hysmith, John H. Moczygemba

Changes in Crappie Population Structure Following Restrictive Harvest Regulations Crappie Pomoxis spp. population structure on Arbuckle Reservoir was monitored from 1984-1997 using fall trap-net samples. A creel survey was conducted from 1985-1995. A 254-mm length limit/15-fish daily creel regulation was placed on the lake 1 January 1993. Prior to the length limit, the population was characterized as fast-growing and short-lived. Angler harvest steadily increased after the length limit and in the final year of the creel survey, yield (kg/ha) was higher than in 5 of the 8 years data were collected prior to the length limit. Angler acceptance of the length limit was high.

Flood and Debris-flow Effects on Virginia Brook Trout Populations Streams and rivers in the Blue Ridge Mountains of Virginia provide an excellent cold water resource and have historically supported exceptional wild trout populations. In June 1995, a flood of greater than 500-year recurrence interval created a unique opportunity to assess the impact on trout populations within 3 rivers of the Shenandoah National Park (SNP). Debris flows impacted the lower one- to two-thirds of the Rapidan, Staunton, and North Fork Moormans rivers, either extirpating or greatly depressing trout populations. Price P. Smith, James B.

Seasonal Fluctuations in Growth and Condition of Trout in a Southeastern Tailwater Growth and condition of rainbow trout and brown trout in the Caney Fork River below Center Hill Dam in middle Tennessee were investigated for 1 year. Rainbow trout stocked in that spring grew faster (13 mm and 20 g/month) than rainbow trout stocked in June and August 1997. Brown trout grew slower in summer and fall (8 mm and 10 g/month) in summer and fall and faster (17 mm and 61 g/month) in winter. Adjusted mean weight of brown trout dropped from 141 g in May 1997 to 113 g in October 1997. Rainbow trout stocked in summer 1997 lost 14% of their body weight by fall 1997. George J.

Alternative Methods to Predict Fish Proximate Composition We used a multiple linear regression approach to develop models predicting water, protein, and lipid content of bluegills (Lepomis macrochirus) under 4 measurement approaches varying in terms of time and money. Inputs were length, weight, relative weight, total body electrical conductivity, and water. Models predicting water and protein weights were very accurate (<5% mean error). No regression predicting lipid weight was accurate enough to be used as a predictor (>37% mean error). We then attempted to reduce inaccuracy by standardizing lipid weight 4 ways.

Utility of Scales and Whole Otoliths for Aging Largemouth Bass in North Carolina Fishery managers routinely collect scales from black basses (Micropterus spp.) for age determination; however, the validity of these ages is often unknown. The objectives of this study were to evaluate the accuracy and precision of scales and whole otoliths relative to sectioned otoliths for determining ages of largemouth bass (M. salmoides) in North Carolina. Scales and sagittal otoliths were collected from largemouth bass during spring and summer of 1997 from the Chowan river, Neuse River, B. E. Jordan Reservoir, W.

Population Characteristics and Management of Black Bass in Eastern Oklahoma Streams We surveyed black bass (Micropterus spp.) populations in Baron Fork in northeastern Oklahoma and Glover River in southeastern Oklahoma during 1994 and 1995 to assess population characteristics and management options particularly for smallmouth bass (M. dolomieu) in eastern Oklahoma streams. Smallmouth bass dominated the catch of black bass species in both streams during both years. The fishery potential for smallmouth bass in Glover River was limited in part by low abundance, poor year-class success, and high annual mortality resulting in low recruitment to older ages. Paul E.

Dispersal of Black Bass following Tournament Release in an Oklahoma Reservoir Largemouth bass (Micropterus salmoides) were tagged and released following a series of weekly tournaments at Lake Thunderbird, Oklahoma, in 1993. Forty-nine percent of the 176 fish recaptured in 1993 were caught within 0.8 km of the release sight and 64% were caught within a 1.6-km radius. Dispersal during the second year was slightly greater with 35% of the 56 recaptured bass coming from within 0.8 km and 46% from 1.6 km of the release site. The maximum distance from the release site that a tagged fish was recaptured was 12 km with a median distance of 1.6 km after 18 months.

White Perch Invasion of B. Everett Jordan Reservoir, North Carolina From 1987 to 1998, gill netting was conducted annually in Jordan Lake, North Carolina, usually 3 times per year with 9 nets distributed over 3 reservoir sub-basins. White perch (Morone americana) began appearing in gill-net samples in 1988. By 1993 they were the second-most abundant species (11.2/net night), following black crappie (Pomoxis nigromaculatus) (21.2/net night). White perch catch rates in 1994 (16. I/net night) exceeded rates for other fish captured in gill nets. White perch continued to constitute a large percentage (21.1%) of the gill-net catch from 1995-1998. Russell K. Wong, Richard L.

Evidence of Striped Bass Spawning in the Upper Coosa River Basin, Georgia Striped bass have been stocked into the Upper Coosa River Basin (Alabama and Georgia) since the 1970s. The increased presence of small striped bass within these waters in recent years suggested the possibility of a resident spawning population. Ichthyoplankton samples were collected once or twice per week from April to June 1997 and 1998 from sample sites in the tributaries of the Coosa River above Weiss Reservoir. Fertilized striped bass eggs were collected from the Oostanaula River during both years and the Conasauga River in 1998 (the only year sampled). William T. Davin, Jr., Jodi Hodges, Christina Hoffman

Buffalo Springs Reservoir is highly eutrophic with a dense population of large gizzard shad (Dorosoma cepedianum) and limited production of young gizzard shad. Fingerling (40 mm total length) striped bass (Morone saxatilis) were stocked into Buffalo Springs Reservoir in 1992 and 1993 at a rate of 550/ha to restructure the gizzard shad population. Three to 4 years after these stockings, density of large gizzard shad declined and a strong gizzard shad year class was produced. White crappie (Pomoxis annularis) recruitment paralleled gizzard shad recruitment. Charles R. Munger, Harold L. Schramm, Jr., Joseph E. Kraai

Striped bass (Morone saxatilis) stocking rates were increased in 1988 and more restrictive harvest regulations were initiated in 1992 to increase striped bass abundance in Lake Normal, North Carolina. The objective of this study was to make inferences about current forage sufficiency for striped bass from length at age of capture and body condition of striped bass collected since 1994. Fish were obtained from November-January fishing tournaments and gillnet sets in 1994-1998. Scott L. Van Horn, Barry Kim Baker, Mark Rash

Use of Infrared-triggered Cameras and Monitors in Aquatic Environments The use of infrared-triggered activity monitors in wildlife science has increased during recent years. In most cases, trail monitors are mounted to stationary objects. However, trail monitors in aquatic environments where change in elevation is necessary, because of varying water levels, curently restricts their use. In our study of Florida Key deer, we needed information on deer activities in areas influenced by tides. We developed an inexpensive device that allowed trail monitors to operate as tides changed.
