Biodiversity Response to Fire and Herbicide in Intensively-managed Pine Stands of Mississippi Common mid-rotation forest management practices in intensively-managed pine (Pinus spp.) stands include thinning, fertilization, herbicide use, and prescribed burning. However, greater herbicide use and less prescribed fire have generated questions regarding treatment effects on biological diversity within these systems. Raymond B. Iglay, Darren A. Miller, Bruce D.

Wetlands created by American beaver (Castor canandensis) provide habitat for a diversity of resident and migratory birds. To estimate bird community characteristics of beaver wetlands and adjacent riparian forests, we conducted point count surveys in five beaver wetlands and adjacent floodplain ridges of first- and second-order streams during winter 2001-2002 and spring 2002 in central Mississippi. Ninety bird species were recorded in beaver wetlands and 69 bird species were detected in adjacent upland forests. Jeanne C. Jones, Katherine E. Edwards, Jarrod H. Fogarty, Kathy Shelton

Breeding Bird Community Responses to Growing Versus Dormant Season Prescribed Fire Prescribed fires are frequently used to restore and maintain pine savanna in the southeastern United States. Although several declining bird species occur within these pine savannas, few studies have directly compared the effects of growing versus dormant season prescribed fires on breeding birds. Therefore, we compared the effects of growing- versus dormant-season prescribed fires on breeding bird communities in mature pine (Pinus spp.) stands within the Fort Benning Military Reservation in west-central Georgia.

Bringing Back Aquatic Diversity, The Pigeon River Recovery Project In 2001, a cooperative effort was begun to restore native fish populations to the Pigeon River, once so polluted that all mollusks and many fish species were extirpated. Volunteers from federal and state agencies, industry, and private organizations created the Pigeon River Recovery Project to begin re-introduction of fish and other aquatic species. Early successes in Tennessee led to the expansion of the project into western North Carolina. Joyce A. Coombs, J. Larry Wilson, Jonathon E. Burr, Larry Everett, Steven J. Fraley, Thomas Russ

Characterizing Reational Use of Public Hunting and Fishing Lands in Virginia Wildlife management areas (WMAs) provide opportunity for both traditional hunting and fishing recreation as well as non-consumptive wildlife-related recreation. Although declining participation in traditional wildlife recreation is well documented, little information exists regarding non-traditional stakeholders who recreate on public hunting and fishing lands; non-consumptive use is perceived to be increasing. Our purpose was to characterize recreational users on WMAs owned by the Virginia Department of Game and Inland Fisheries (VDGIF) and estimate how much use these areas receive. Amy L. Carrozzino, Steve L. McMullin, James A. Parkhurst

Conservation and the Courts: Barriers to Wildlife Law Enforcement in Georgia In Georgia, where this study was conducted, the size of the fine a violator pays for a wildlife citation is dependent on the county and the specific court in which he or she is sentenced. A highly politicized court system and complex intergovernmental relationships have led to uneven enforcement of game and fish laws in the state. This lack of uniform enforcement reduces the deterrent effect of the work of conservation rangers.

Development of a Crowded Largemouth Bass Population in a Tropical Reservoir This case study examines the development of an overcrowded largemouth bass population following initial stocking in a tropical reservoir and efforts to correct crowding with a protected slot length limit. Cerrillos Reservoir is a relatively new impoundment (filled 1996) in Puerto Rico and is one of only two reservoirs that have been stocked exclusively with pure Florida largemouth bass (Micropterus salmoides floridanus). Largemouth bass were first stocked in Cerrillos Reservoir in 1997 and the population quickly expanded. Cynthia N. Fox, J. Wesley Neal

Diet and Population Metrics of the Introduced Blue Catfish on the Altamaha River, Georgia Blue catfish (Ictalurus furcatus) were first detected in the Altamaha River, Georgia, during an access creel survey in 2005 and subsequently in 2006 during annual ictalurid sampling. Introduction of this species in the Altamaha River is believed to have occurred via escape from normal upstream reservoir releases from Lake Sinclair and Lake Oconee. Relative abundance, as indexed by electrofishing catch rate (fish per hour), has increased from 2.9 ± 1.0 SE in 2006 to 38.8 ± 8.2 SE in 2011. The size of blue catfish captured ranged from 56 to 820 mm total length and 0.001 to 7.7 kg. Timothy F. Bonvechio, Cecil A. Jennings, Donald R. Harrison

Dispersal and Dam Passage of Sonic-tagged Juvenile Lake Sturgeon in the Upper Tennessee River More than 90,000 state-endangered lake sturgeon (Acipenser fulvescens) have been stocked into the French Broad River, Holston River, and Fort Loudoun Lake in the upper Tennessee River system. Although incidental reports of anglers catching these fish have increased, little is known about their fate after stocking. Therefore, this study was conducted to evaluate lake sturgeon dispersal throughout the system. William R. Collier, Phillip W. Bettoli, George D. Scholten

Dispersal, Mortality, and Predation on Recently-stocked Rainbow Trout in Dale Hollow Lake, Tennessee Forty-four hatchery-raised rainbow trout (Oncorhynchus mykiss) were implanted with ultrasonic tags and stocked into Dale Hollow Lake, Tennessee, and tracked at least once per week for eight weeks to describe post-stocking dispersal rates, movements, and habitat use. Dispersal followed a three-stage pattern characterized by rapid movement away from each stocking site during the first week, relatively little dispersal during the next three weeks, and further dispersion during the final four weeks that fish were tracked.

Sustainable management of wild turkeys (Meleagris gallopavo) requires information on distribution and abundance across the range. Techniques for surveying wild turkey populations in Texas are constrained by land access issues, requiring integration of landowners and managers into monitoring activities. We evaluated the use of 1) aerial surveys for estimating the distribution of Rio Grande wild turkeys (M. g. intermedia) relative to roosting habitat, and 2) multiple-observer roost counts for estimating local turkey abundance and roost-site fidelity within the Texas coastal sand plain.

Economic Impact of Striped Bass Angler Visitation at a Rural Alabama Reservoir Lewis Smith Lake is an 8,853-ha recreational fishery within the Black Warrior River basin near Jasper, Alabama. A recent study found that striped bass Morone saxatilis do not significantly impact largemouth bass Micropterus salmoides and Alabama bass M. henshalli through competition and predation, though many anglers still believe this to be true. Costs incurred by the Alabama Division of Wildlife and Freshwater Fisheries annual striped bass stocking efforts on Lewis Smith Lake are compared with the regional economic gain from the existence of this fishery.

The striped bass (Morone saxatilis) population of the Savannah River estuary declined in the 1980s, likely because of the operation of a tide gate that increased salinity on spawning grounds and accelerated seaward transport of eggs and larvae. Following discovery of this negative effect, periodic egg sampling monitored striped bass reproductive effort and documented a 96% decline in egg density (n/100m3) from pre-tide gate levels. The decline in egg density was concomitant with a similar decline in the adult striped bass population. Thomas R. Reinert, Cecil A. Jennings

Commercial pine (Pinus spp.) forests in the southeastern United States are critical to providing fiber for global wood supply needs. Intensive forest management techniques including row spacing and woody debris distribution can impact plant communities. Therefore, we quantified response of plant communities in replanted P. taeda stands to mechanical site preparation at two levels of row spacing (narrow and wide) and two methods of distributing woody debris (piling and scattering) following harvest in Louisiana.

Evidence of a Bull Shark Nursery in the Altamaha River Estuary, Georgia The National Marine Fisheries Service (NMFS) has developed fishery management plans for sharks that require delineation of nursery areas, monitoring of relative abundance of juveniles in these areas, and identification of habitat relationships between juvenile sharks and the nursery environment. Netting surveys conducted during 2008 and 2009 in the Altamaha River Estuary suggested that the estuary served as both a primary and secondary nursery for bull sharks (Carcharhinus leucas) in 2008 and limited use as a secondary nursery in 2009.

Largemouth bass (Micropterus salmoides) on the Arkansas River have been regulated by a 381-mm minimum-length limit (MLL) regulation since 1 January 1998; however, little evaluation of this regulation has been conducted. During 2004-2005 and 2010, largemouth bass populations were sampled from throughout all navigation pools in the Arkansas River. All bass were aged using sagittal otoliths, and population metrics were calculated to conduct simulation modeling using the Fisheries Analyses and Simulation Tools (FAST) software. Clint R. Peacock, Benjamin G. Batten, Michael A. Eggleton

Fishery Viability of a Wild Brown Trout Population in the Chattahoochee River near Atlanta, Georgia Brown trout (Salmo trutta) were first introduced as part of a put-and-take fishery in the Chattahoochee River below Buford Dam in the 1960s. Wild, young-of-year (YOY) brown trout were observed in the river in the 1990s and annually in subsequent years. The Georgia Department of Natural Resources implemented a stocking moratorium on brown trout between Buford Dam and Morgan Falls Dam beginning in 2005 and this study evaluated existing population monitoring data before and after implementation of the moratorium to better understand the potential of a completely wild brown trout fishery.

Habitat Selection and Survival of American Black Ducks in Western Tennessee The American black duck (Anas rubripes) has been declining throughout its range since the 1950s, especially in the Mississippi Flyway. Loss of quality wintering habitat and competition and hybridization with mallards (A. platyrhynchos) have been suggested as factors contributing to black duck decline. Tennessee and Cross Creeks National Wildlife Refuges (NWRs) are two primary wintering areas for midcontinent black ducks recording long-term population declines. Kira C. Newcomb, J.

Impacts of Precipitation on Northern Bobwhite Production in South Texas Despite a long history of research on northern bobwhites (Colinus virginianus; hereafter, bobwhites), there has not been a comprehensive assessment of how bobwhite productivity varies across a landscape in relation to environmental factors such as weather. Due to concerns of global climate change and range-wide decline of the bobwhite, further understanding the relationship between weather and bobwhite population dynamics is needed. Andrew N.

Rice fields are important agricultural habitats for waterbirds (waterfowl, shorebirds, wading birds) worldwide. In the Texas Mid-Coast (TMC) and Louisiana Chenier Plain (LCP), >167,458 ha of rice are cultivated annually. Precise estimates of abundance of waste grain and natural seeds in harvested and idle rice fields are needed to guide conservation of waterbird habitat in this region, which is part of the Gulf Coast Joint Venture (GCJV) of the North American Waterfowl Management Plan.

The Louisiana black bear (Ursus americanus luteolus) was listed under the U.S. Endangered Species Act as Threatened in 1992. The U.S. Fish and Wildlife Service cites loss of habitat as the primary cause of population decline, along with human-related mortality as a secondary cause. One of the delisting criteria in the Recovery Plan for the Louisiana black bear is that two of the three subpopulations must be viable, one in the Tensas River Basin and one of the two in the Atchafalaya River Basin.

The Recreational Snag Fishery for Paddlefish in Cherokee Lake, Tennessee No information existed on the recreational snag fishery for paddlefish (Polyodon spathula) in Cherokee Lake in eastern Tennessee, purportedly the largest such fishery in the state. Therefore, a roving creel survey was conducted during the 15-day season in March 2008, 2009, and 2010. The fishery could be characterized as a a destination fishery in that 448 anglers in 239 parties drove an average of 80 km one-way (± 2.43 SE; range: 2-352) to participate. Most (67%) anglers were Tennesseans, followed by residents of Virginia (26%) and three other states.

Temporal Comparisons of Electrofishing Efficacy for Largemouth Bass in a Small Puerto Rico Reservoir Largemouth bass (Micropterus salmoides) are the primary sport fish in Puerto Rico reservoirs and the majority of management efforts directed at this species primarily employ electrofishing in sampling activities. However, little attention has been given to evaluating electrofishing sampling efficiency in these systems. Nick R. Peterson, J. Wesley Neal

Survival and Recovery of Normal Wild vs. Relocated Adult Resident Canada Geese in Georgia, 2000-2009 Georgia's growing resident (non-migratory) Canada goose (Branta canadensis) population often causes nuisance problems in urban areas. One method of reducing nuisance goose problems is capture and relocation, especially if geese are relocated to rural areas where hunting may occur. To determine if relocated geese have different survival or band recovery rates than normal wild geese, I estimated probabilities of survival and recovery for adult, resident Canada geese between 2000 and 2009 using banding and dead recovery data from normal wild geese and from relocated geese in Georgia.

Success and Failures of an Ecological Detection-dog Service The use of detection dogs in ecological research and management continues to grow. Two years ago, a collaborative effort was formed at Auburn University with the goal of training detection dogs for use in ecological research. Here we provide details about the projects for which we have used dogs, measures of success for those projects, and lessons learned. We have successfully used dogs in the field to find scat from black bear (Ursus americanus), bobcat (Lynx rufus), gray fox (Urocyon cinereoargenteus), and coyote (Canis latrans). Todd D. Steury, T.

Spatial Education: Exploiting Space-structured Decision-making to Reduce Management Uncertainty Adaptive management is a form of structured decision-making designed to guide management of natural resource systems when their behaviors are uncertain. The basic elements of adaptive management include a setting in which a recurring decision is to be made, a stated objective of management, a set of predictive models that represent competing hypotheses about system behavior, and a program of monitoring to repeatedly assess relative credibility of the models. Thus, management itself is used to inform future management and to consequently improve conservation delivery through time. Clinton T. Moore, Jill J. Gannon, Terry L. Shaffer

Spatial Characteristics of Black Bears and Bear Hunters in Garrett County, Maryland Harvest vulnerability is an important consideration for the proper management of a black bear population. To assess harvest vulnerability, we must first understand black bear and bear hunter spatial characteristics. Global positioning system (GPS) technology allows us to record this information with more accuracy and efficiency than previous methods used by researchers. We used GPS and a geographic information system (GIS) to examine the spatial characteristics of bears and bear hunters in Garrett County, Maryland during the 2005-2007 bear hunting seasons.

Seasonal Space Use and Habitat Selection of Female Wild Turkeys in a Louisiana Bottomland Forest Space use and habitat selection of wild turkeys (Meleagris gallopavo) has been well studied in various upland landscapes, but information within bottomland hardwood systems is lacking. Turkeys in bottomland systems face unique situations (e.g., flooding) and turkey behavior observed in upland systems may not directly apply to bottomland systems. Frederick G. Kimmel, Michael E. Byrne, Michael J. Chamberlain

Seasonal Habitat Shifts by Benthic Fishes in Headwater Streams Fish-habitat associations in streams have been widely studied; however, temporal considerations have been neglected, particularly during the winter. We quantitatively sampled perennial headwater streams in the Missouri Ozarks during the summer (n = 13) and winter (n = 4) to evaluate possible habitat shifts by three benthic fishes at two spatial scales: channel unit and microhabitat.

The importance of floodplain habitats to biotic communities has long been acknowledged. Many large river systems, however, are heavily regulated by dams that alter natural flood pulses and restrict large volumes of water from entering floodplains. We were interested in determining how alterations in flow regime may affect communities of fishes and invertebrates in floodplains along the Savannah River. Jeffrey A. Garnett, Darold P.

Improvement of a Catch-per-unit-effort Estimator for White-tailed Deer Populations Catch-per-unit-effort (CPUE) is a useful index of population density that is often applied to harvested populations. Because CPUE is an economical index and data collection is simple, we wanted to enhance the user-friendliness and accessibility of a tool for tracking deer population abundance by recoding an existing FORTRAN estimator to JMP scripting language (JSL).

Aquatic invertebrates provide protein-rich foods for dabbling ducks (Anatini) and other waterfowl throughout their annual cycle. During winter, some species (e.g., mallard [Anas platyrhynchos]) undergo molt and acquire body reserves for migration and egg formation, which increase protein demands met primarily through consumption of invertebrates. Habitat managers often flood unharvested agricultural crops to increase energetic carrying capacity for waterfowl. However, few studies have estimated abundance of invertebrates in flooded croplands.

Many studies have reported that imported fire ants can have negative impacts to property, wildlife, and ecosystem integrity. Depredation by fire ants can reduce native insect diversity and survival of hatchling birds and reptiles, including gopher tortoises. Because of the potential impacts of fire ants on gopher tortoise recruitment, we assessed infestation levels of red imported fire ants on public and private forest lands in south Mississippi. Our study design focused on surveys for estimation of densities of fire ant mounds on suitable and priority soils for gopher tortoises. Jeanne C. Jones, W.

Native Strain Walleye Management Efforts in Kentucky Historically, many Kentucky rivers had native walleye populations with fish that grew to impressive sizes and supported popular sport fisheries. Due in part to reservoir constructions and a variety of other factors, these populations gradually declined. By the 1970s, the huge spring walleye runs in these rivers had disappeared, so the Kentucky Department of Fish and Wildlife Resources (KDFWR) began stocking walleye from northern origins in some of these same rivers and the new reservoirs.

While the downstream effects of dams on fish habitat have long been recognized, broad-scale assessments of tailwater fish habitat have rarely been conducted. In this paper, I report on the status of tailwater fisheries in Oklahoma as determined through a web-based survey of fisheries biologists with the Oklahoma Department of Wildlife Conservation conducted in July 2010. Respondents addressed 38 tailwaters, encompassing all major areas of the state.

Predicting North Carolina Landowner Participation and Interest in Wildlife Related Fee Access Wildlife-related fee access can provide supplemental income to private landowners, potentially protecting wildlife habitat by keeping land undeveloped. We surveyed 1,368 private landowners in North Carolina to determine the factors influencing whether they leased land to hunters or were interested in offering leases for other types of wildlife related recreation. Five percent of landowners allowed access for fee hunting. Twenty-eight percent of landowners provided access to their property for wildlife related activities, but <1% of these landowners earned income from it. Katherine E. Golden, Christopher S.

Habitat loss, habitat degradation, and agricultural intensification are primary factors contributing to the decline of many birds that use grasslands, including the endangered grasshopper sparrow and the northern bobwhite. Current grazing practices in the Mid-South focus on getting high yields from dense, monotypic stands of non-native forages, which provide no bare ground, little vertical structure, and poor plant species richness.

Restoration of Breeding Habitat for Rare Amphibians Although fire is recognized as an important disturbance in longleaf pine uplands of the southeastern United States, less is known about the importance of fire or other disturbances in the wetlands embedded in this system. Reticulated flatwoods salamanders (Ambystoma bishopi), a federally endangered species, breed in the grassy understory of ephemeral pine flatwoods wetlands. These areas contain water in the winter, but are dry by April or May in most years, making it possible for them to burn during the summer lightning season. Thomas A. Gorman, Carola A. Haas, John G.

Nest Site and Microhabitat Selection by Key Largo Woodrats Reductions in habitat quantity and quality have contributed to precipitous declines in the Key Largo woodrat (Neotoma floridana smalli) population over the last 30 years. Additional information on microhabitat and nest site selection is needed to increase quality of the remaining habitat and increase the population. In 2005-2006, we evaluated microhabitat selection by comparing structure and composition of vegetation at known woodrat locations to random locations in available areas.

Evaluation of Methods for Monitoring Long-term Population Trends in Cave-roosting Bats Because numerous cave-roosting bat species are experiencing population declines, especially those affected by the white-nose syndrome epizootic, it is essential to establish rigorous monitoring protocols to accurately track population trends over time. We tested the efficacy of low-cost visual counts to effectively monitor population trends of southeastern myotis (Myotis austroriparius) at a maternity-roost in southwestern Georgia. We conducted visual counts during evening emergence events using white light illumination. Tara J. Thomson, Jason A. Scott, Steven B. Castleberry

Effects of Mechanical Manipulation and Time on Lead Pellet Distribution in Arkansas Wetlands Lead poisoning occurs when birds forage in habitats containing lead pellets and ingest and store pellets in their digestive systems. Lead pellets have been banned from use in waterfowl hunting in the United States since 1991; however, residual pellets may remain in wetlands and be available to foraging waterfowl. Elisabeth B.

Effect of Increased Egg Stocking Density in Existing and Experimental Catfish Incubators Channel catfish egg masses are typically incubated in stationary wire mesh baskets suspended in metal troughs with flow-through water that is agitated and circulated between the baskets and around the eggs with rotating paddles. A limiting factor in the successful incubation of channel catfish egg masses is the absorption of oxygen by the developing embryos; low levels of dissolved oxygen in the water result in premature hatching and increased fry mortality. We modified and tested a vertical-lift incubator (the “See-Saw”) for incubating channel catfish egg masses. Brian D. Ott, Eugene L. Torrans

Effects of GPS Sampling Intensity on Home Range Analyses The two most common methods for determining home ranges, minimum convex polygon (MCP) and kernel analyses, can be affected by sampling intensity. Despite prior research, it remains unclear how high-intensity sampling regimes affect home range estimations. We used datasets from 14 GPS-collared, white-tailed deer (Odocoileus virginianus) to describe the size and location accuracy of home range estimates calculated from different sampling regimes.

Effects of a Supplemental Food Source and Nest Density on Success of Artificial Ground Nests Nest predation can limit avian recruitment and may be a proximate source of population declines in many avian populations. Because nest predation may be affected by availability of alternative foods and nest density, we used artificial nests and track counts to evaluate effects of supplemental food and nest density on nest success of artificial ground nests. Nest success was lower at 7 of 9 nest density classes when a supplemental food source was present. David D. Jones, L. Mike Conner, Robert J. Warren, Glenn O. Ware
