To determine habitat selection of selected carnivores, we set up 15 remotely-triggered infrared camera stations across a 30-km2 section of the Mountain Lake Biological Station in Southwest Virginia. To maintain independence, a distance of 1 km was kept between each station. We monitored the camera stations for 942 trap nights. Raccoons (Procyon lotor) had the greatest trap success (3.03%) followed by black bear (Ursus americanus; 2.23%), coyote (Canis latrans; 1.09%), bobcat (Lynx rufus; 0.67%), and gray fox (Urocyon cinereoargenteus; 0.00%).

Canada Warbler Habitat Suitability in an Active Industrial Forest in West Virginia Canada warbler (Wilsonia canadensis), a woodland breeding songbird of special concern in West Virginia, has been declining throughout its range at a rate of 3.5% since 1980 (0.5% within West Virginia and 4.6% in the Allegheny Plateau Physiographic Region). While Canada warblers use primarily moist mixed coniferous-deciduous forest, they can be disturbance specialists at higher elevation locations in the southern portion of their range, including West Virginia, suggesting timber harvests might be an effective management option.

Capture Efficiencies of the Holton and Sullivan Parallel Wires Electrofishing Method The estimation of fish abundance in small streams is often accomplished with removal sampling and an electrofisher. Several electrofishing gears are available, and studies have compared different gear types as well as different sampling techniques, such as the number of passes, with the same equipment. We conducted seven-pass electrofishing removal sampling with two sampling gears (a backpack DC electrofisher and a parallel wire AC electrofisher) within the upper Greenbrier River drainage, West Virginia. We compared the two gear types at 10 paired-sites based on capture efficiencies.

Chronic Wasting Disease Surveillance and Response to Detection in White-tailed Deer in West Virginia In September 2005, Chronic Wasting Disease (CWD) was confirmed in a 2.5-year-old male white-tailed deer in central Hampshire County as part of routine surveillance initiated in West Virginia in 2002. While awaiting confirmation of this first known occurrence in the state, the West Virginia Division of Natural Resources (WVDNR) initiated its CWD Response Plan. The goal of this plan is to guide decision-making in defining distribution and frequency of the disease in deer populations and attempt to prevent the spread of CWD to cervids in uninfected areas.

Classification and Ordination of Freshwater Mussel Communities in the Appalachians The Appalachian Region contains the greatest diversity of freshwater mussels in the world. Freshwater mussels are also the most endangered taxa in the United States. Although small-scale studies have identified threats to mussel fauna, few studies have examined patterns in decline at the watershed scale. Mussel community types are not widely used in the literature, making it difficult to propose appropriate sampling designs for large-scale research. Alison R. Mynsberge, George Merovich, Jacquelyn M. Strager, Michael P. Strager, Patricia M. Mazik

Various techniques are available to enhance wildlife quality in coastal wetlands. A new technique is terrace construction. Terraces are constructed by dredging shallow open water areas and piling the dredged material to form an exposed surface that are planted with wetland vegetation. Unlike spoil banks, which are continuous and rise above normal tides, terraces are discontinuous and flood at high tide. Constructing terraces gained popularity as a restoration and mitigation technique since the first terraces were constructed in 1993 on Sabine National Wildlife Refuge.

Current Trends in Catfish Sampling Techniques and Information Needs Catfish managers and researchers were asked to participate in an online survey describing current information needs, sampling techniques, and known gear biases for projects during 2002-2006. One hundred eighty two responses were collected in a four-month period in early 2006. Channel catfish (Ictalurus punctatus) were the most targeted species, followed by flathead (Pylodictis olivaris) and blue (I. furcatus) catfish, respectively. A variety of methods were used to collect catfishes.

Science-based monitoring of biological resources is important for a greater understanding of ecological systems and for assessment of the target population using theoretic-based management approaches. When selecting variables to monitor, managers first need to carefully consider their objectives, the geographic and temporal scale at which they will operate, and the effort needed to implement the program. Generally, monitoring can be divided into two categories: index and inferential. Jon D. Klimstra, Allan F. O'Connell Jr., Mark J. Pistrang, Laura M. Lewis, James A. Herrig, John R. Sauer

Detection of Viral Antigens for WNV and SLE by rt-PCR in Wild Turkey from South Georgia West Nile virus (WNV), St. Louis encephalitis virus (SLE), eastern equine encephalitis virus (EEE), and avian influenza virus (AI) are zoonotic pathogens that affect many species including wild turkey (Meleagris gallopavo). Several studies have documented serum antibodies to these pathogens in wild turkey; however, few studies have tested for the presence of viral antigen in tissues. Therefore, we initiated a study to test samples of multiple organs (heart, liver, kidney, spleen, brain, testes, and lung) from opportunistically-collected wild turkey for the presence of these viruses.

Fragmentation and loss of habitat at local and regional scales have been implicated as important factors contributing to declines of forest bird populations. Large-scale activities such as surface mining can alter the spatial configuration, increase edge:area ratio, and reduce overall patch size of forested habitats. These factors can negatively affect mature-forest dependent species such as the cerulean warbler (Dendroica cerulea).

Economic Impacts of White-tailed Deer Hunting in Mississippi We conducted a five-year study during the 2001-2005 hunting seasons to determine the economic impacts of white-tailed deer (Odocoileus virginianus) hunting in Mississippi. Activity days for state residents ranged from 2,390,619 to 3,181,957 and for non-residents, 265,103 to 357,253. Total economic impacts ranged from US $761 million to $1.03 billion (in 2007 dollars). Over the five years, number of full- and part-time jobs supported by deer hunting activities ranged from 26,489 to 37,888. Aggregated economic sectors benefiting the most were services, manufacturing, and trade. Stephen C. Grado, Kevin M. Hunt, Micah W. Whiteside

River herring (alewife [Alosa pseudoharengus] and blueback herring [A. aestivalis]) within the Albemarle Sound basin in North Carolina once supported large commercial fisheries that have declined dramatically since the 1970s. Overfishing, poor water quality, and habitat loss have been suggested as causes of this decline. The objective of this study was to examine the effect of water quality on the hatching success of blueback herring eggs in the Chowan River, a major tributary to Albemarle Sound. Christian T. Waters, Joseph E. Hightower

The cerulean warbler (Dendroica cerulea) is one of the highest priority bird species in the eastern United States because populations have declined 4.3% annually during 1966-2005 based on Breeding Bird Survey (BBS) data. Habitat loss and fragmentation due to land use changes is thought to be one of the major factors contributing to the decline. BBS routes, the primary source for monitoring bird population trends, include 50 sampling stops every 0.8 km. Patrick McElhone, Petra Bohall Wood, Deanna Dawson

Efficacy of Spring Herbicide Applications for Fescue Control: A Comparison of Three Products The Conservation Reserve Program (CRP) was designed to remove highly erodible cropland from production. Although wildlife habitat benefits are an important component of CRP, millions of hectares of CRP do not produce optimal wildlife benefit because of poor cover crop choice. Kentucky-31 tall fescue (Festuca arundinacea; hereafter, fescue) was one of the most commonly planted grasses on CRP fields but provides relatively poor habitat for grassland birds such as northern bobwhites (Colinus virginianus).

Ensuring Public Support for Ecological Restoration Projects Ecological restoration projects have come and gone over the years. Some have succeeded and others have failed. The projects that have succeeded in the long run have one element in common: society decided to adopt and support the fundamental concepts of the restoration project. The Missouri Department of Conservation's (MDC) Alligator Gar Restoration project began with almost immediate support for various reasons. This was not by accident. MDC involved the Missouri public in a variety of ways to gain social acceptance for a species that had been hated for decades.

The Eastern Brook Trout Joint Venture (EBTJV) was formed to implement range-wide strategies that sustain healthy, fishable brook trout populations across the entire range of the eastern brook trout (Salvelinus fontinalis). In order to accomplish the goals of the EBTJV in West Virginia we set out to accomplish the following objectives: to assess brook trout populations where current data is lacking and to set restoration priorities for stream reaches within this area based on both reach and subwatershed scale connectivity.

Evaluating Habitat Value for Red-cockaded Woodpeckers Using Individual-based Modeling We have developed a user-friendly geographic information system (GIS)-based, spatially-explicit decision support system (DSS) using red-cockaded woodpecker (RCW; Picoides borealis) habitat and population information to help land managers identify and prioritize critical habitat patches. Using state-of-the-art spatial modeling and GIS technologies, we coupled an existing, validated, and peer-reviewed individually-based, spatially-explicit RCW population model with actual landscape features in a user-friendly DSS format.

Evaluation of a New Sediment Sampling Device A two-part sediment sampler (stationary base and removable trap) was designed for a long-term study of stream sedimentation associated with highway construction. Before the long-term study, a laboratory study in an experimental flume examined efficacies of our sampler and two other sediment samplers: a modified core sampler and Whitlock-Vibert boxes. Based on the flume experiment, the efficacy of our sediment sampler was consistent with that of core and Whitlock-Vibert samplers. Lara B. Hedrick, Stuart A. Welsh, James T. Anderson, James D.

Evaluation of Survey Techniques for Wild Turkey in the Southern Great Plains Few studies have assessed methods of estimating abundance, density, and trends of wild turkey (Meleagris gallopavo) populations and most wild turkey survey efforts have been unstandardized, unsuccessful, or limited to small scales. However, successful large-scale monitoring programs are important to management decisions and evaluating management activities. Our objectives were to evaluate survey techniques for wild turkey.

We evaluated three low frequency electrofishing pulse rates (30, 15, and 7.5 pulses per second [pps]) for differences in relative abundance, size structure and species composition of catfish species in two north Florida rivers (Apalachicola and Suwannee). Three species of catfish were collected from each river: Apalachicola River-flathead catfish (Pylodictis olivaris), channel catfish (Ictalurus punctatus), and blue catfish (I. furcatus); Suwannee River-spotted bullhead (Ameiurus serracanthus), channel catfish, and white catfish (I. catus).

Evidence of Stock-recruit Relationships for Appalachian Brook Trout Stock-recruit (SR) relationships have been reported for numerous stocks of trout and Pacific salmon, but despite the intuitive appeal, evidence of such relationships is lacking for brook trout (Salvelinus fontinalis). The relationship between number of adults spawning in a stream and the subsequent number of young produced can be used by management to predict year class strength. Disruptions of SR relationships (for species that exhibit strong relationships) can be indicative of environmental perturbations or habitat impairment. Kyle J. Hartman, M. Beth Adams, Michael D.

Fish Movement in a Large Navigation River System Fish movement is an important ecological component to the any lotic ecosystem. The Ohio River was once a large free-flowing system, but since the early 1880s this large river system has been altered to its current state of navigation pools and tailwater reaches. To determine movement of highly migratory fish species, a study was conducted on sauger, hybrid striped bass, and paddlefish to ascertain movement patterns and the influence of riverine conditions. Fish were inserted with either t-bar anchor tags (sauger and hybrid striped bass) or coded wire tags with elastomer marks (paddlefish).

Foraging Selection and Behavior of the Cerulean Warbler in Response to Timber Harvests Foraging ecology of cerulean warblers (Dendroica cerulea) is not well studied, yet an understanding of foraging behavior and selection of foraging habitat is important for conservation and management. During the 2006 breeding season, 359 foraging observations were collected on eight study plots in West Virginia and four in Kentucky in a mixture of national forests, state Wildlife Management Area (WMAs), and private forests. We analyzed foraging observations to quantify tree species preference based on use versus availability based on a chi-square goodness-of-fit test. Gregory George, Petra Bohall Wood

The increasing importance of the walleye (Sander vitreus) fishery in the New River, Virginia, and recent research findings showing persistence of a presumptive native stock motivated a seven-year program of hatchery-based restoration of the native fishery. Candidate spawners were collected from spawning areas, and DNA from fin clips was genotyped at two microsatellite loci. Candidates exhibiting alleles at the Svi17 and Svi33 loci that characterize the presumptive native stock were spawned. Their young were reared at one of four fish hatcheries in Virginia and West Virginia. Brian R. Murphy, Daniel Dutton, Eric M. Hallerman, George C.

Methylmercury is the predominant chemical form of mercury reported in the eggs of wild birds. The embryo is the life stage at which birds are most sensitive to methylmercury. Protective guidelines have been based largely on captive-breeding studies done with chickens (Gallus domesticus), mallards (Anas platyrhynchos), and ring-necked pheasants (Phasianus colchicus). Typically these studies are cost and time prohibitive. In the past, researchers have used either egg injections or the “sample egg” technique to determine contaminant effects on bird eggs. Jon D.

In response to dwindling populations of northern bobwhite (Colinus virginianus), the Northern Bobwhite Conservation Initiative and the Missouri Department of Conservation's Strategic Guidance for Northern Bobwhite Restoration are guiding habitat restoration efforts in Missouri. Success of these programs is dependent on restoration of habitat on large tracts of private land. Efficacious selection of restoration areas requires a foundation of ecological and sociological information. Thomas V. Dailey, Ronald A. Reitz, Craig D. Scroggins, Heather J. Scroggins, Thomas B.

The Natural Resource Enterprises Program at Mississippi State University Previous research conducted at Mississippi State University found that non-industrial private (NIP) landowners in Mississippi can diversify incomes derived from their properties through the development of fee hunting enterprises. In 1998, revenues collected from fee hunting on Mississippi private lands ranged from US$2,964 to $5,254 on average per landowner or $7.50 to $14.28 per ha, depending upon the region. Net revenues averaged from $1,539 to $3,244 per landowner survey respondent or $3.90 to $9.54 per ha. W. Daryl Jones, Katherine M. Jacobs, Adam T. Rohnke, T. Adam Tullos, Jeanne C. Jones, Bruce D.

The Effects of Riparian Logging and Large Woody Debris Addition on Stream Morphology Large woody debris (LWD) is an integral part of the ecology of forested headwater streams and has been shown to store organic matter, provide overhead cover, and create pools. Pool creation is of particular interest to resource managers since it forms critical summer refugia for brook trout (Salvelinus fontinalis). We investigated the morphological effects of riparian logging and LWD additions in seven headwater streams in central West Virginia. Each stream was divided into three sections: reference (uncut), logged (50% or 90% riparian basal removal), and logged + LWD additions.

Intersex is a gonadal abnormality in which both testicular and ovarian tissues are present in an organism known to be gonochoristic. This condition has been observed in several locations, one of which is the Potomac River. There are several chemical contaminants with endocrine disrupting properties that have been suggested as possible contributors to intersex. The purpose of this study is to analyze what contaminants are present, and to determine if these have any effect on sperm quality or intersex severity in smallmouth bass (Micropterus dolomieu) in the Potomac.

Otolith chemistry has demonstrated potential for identifying natal origins and tracing dispersal in fisheries across a variety of habitats. Our objective was to assess inter-annual and intra-annual (specifically, within the spawning season) variation of trace element signatures distinguishing different rivers. Our study site was the Upper James River and its tributary the Maury River in western Virginia. We collected smallmouth bass (Micropterus dolomieu) fry from various locations along the length of the Maury River and also from the James within 10 km of their confluence. Brett M.

Quality deer management (QDM) advocates the protection of younger-age white-tailed deer (Odocoileus virginianus) bucks, but the subsequent survival of these animals remains unknown. We conducted a study to investigate the impact and importance of harvest and non-harvest mortality factors on adult male white-tailed deer in Mississippi on areas managed under QDM. We captured 408 deer and fitted 238 adult bucks with radio collars from February 1990 until January 1997. During the study, we documented 185 mortalities, which were used to estimate survival and cause-specific mortality rates. Jacob L. Bowman, Harry A. Jacobson, Daniel S. Coggin, James R.

Survey Questionnaire Wording and Interpretation: Implications for Policymakers The ultimate success of natural resource decision-making depends upon knowledge gathered from several sources; e.g. biological data, institutional values and beliefs, and human dimensions information from affected constituents. Handfishing for catfish has been at the forefront of Missouri conservation since 2000. To determine the acceptability of handfishing to Missouri anglers we conducted a survey of licensed anglers in 2004. Ronald A. Reitz, Heather J. Scroggins, John H. Schulz

The Greenbrier Sporting Club initiated a voluntary stream enhancement and restoration effort to restore trout habitat in nearly 4.02 km of Howard Creek, a perennial stream located near White Sulphur Springs, West Virginia. Howard Creek, which has a 170.94 km2 watershed, receives runoff from the town of White Sulphur Springs, flows through the Greenbrier Resort, and ultimately drains into the Greenbrier River. The effects of urbanization and historic stream modifications have degraded stream habitat and function within Howard Creek.

Spatial Characteristics of Black Bear and of Bear Hunters in Garrett County, Maryland We used GPS technology to examine spatial relations of black bear hunters and black bears (Ursus americanus) in Garrett County, Maryland. During the 2005 hunting season, we equipped 35 hunters and 4 adult female black bears with GPS transmitters to track their movements. We compared the following spatial variables relative to both bear and hunter movements: road corridors, riparian corridors, slope, and habitat type. Hunters used a variety of habitats, with mixed forests and wetlands used in greater proportions than expected. Edward Arrow, John Edwards, Harry Spiker

Spatial requirements and resource selection can influence home range size and use patterns. We examined seasonal patterns of home range size in adult fox squirrels (Sciurus niger) and gray squirrels (Scuirus carolinensis) at Piedmont National Wildlife Refuge in central Georgia. We used radio-telemetry locations (n = 3442) and fixed kernel methodology to estimate size of 40 seasonal home ranges of fox squirrels and 42 of gray squirrels. We determined site fidelity of an individual as the percent overlap between home range estimates in successive seasons (n = 17 fox, 19 gray). Shawn M. Crimmins, John W. Edwards

The National Park Service is dedicated to controlling exotic species if they interfere with natural processes or natural habitats, disrupt the accurate presentation of cultural landscapes, or hamper the land management. Morrow's honeysuckle (Lonicera morrowii) had invaded a 20-acre wet meadow at Fort Necessity National Battlefield in Farmington, Pennsylvania, providing breeding habitat for American woodcock (Scolopax minor). American woodcock populations in the northeastern United States have declined more than 45% since the late 1960s. Holly M. McChesney, James T. Anderson, Constance A. Ranson

Reproductive Consequences of Exposure to Sediment Extracts from the Potomac River on Japanese Medaka Recently an intersex condition, defined as the presence of oocytes in the testes of male gonochoristic fish, has been observed in smallmouth bass in the South Branch of the Potomac River, West Virginia, which indicates exposure to exogenous estrogens. Endocrine disrupting chemicals (EDC's) are generally hydrophobic and would tend to be found within the sediment of aquatic environments. Few studies have attempted to show the effects of exposure to EDCs on fish using sediment chemical extracts. S.R. Davis, C.M. Foran, P.M. Mazik

Quantifying the Value of a Nursery Habitat Using the Spotted Seatrout in an Estuarine System Nursery habitats such as seagrass beds are important for the health and sustainability of many fisheries. In fact, seagrass beds are considered to be essential nursery habitats and as a part of the Sustainable Fisheries Act (SFA) of 1996 it was mandated that these areas be protected. To designate an area as an essential fish habitat two main criteria must be met, 1) greater numbers of fish produced per area and 2) greater survival of juvenile fish to adulthood.

Invertebrate Sampling Considerations in Intensively-managed Pine Stands of Mississippi Understanding bias associated with invertebrate sampling methods is essential for relevant comparisons among studies. As invertebrate research becomes more prevalent, it is imperative that sampling technique efficiency across habitats is understood to facilitate selection of an appropriate sampling framework. Therefore, we compared results from suction sampling and pitfall trapping in intensively managed, mid-rotation pine (Pinus spp.) stands owned and managed by Weyerhaeuser Company near Scooba, Mississippi.
