We used scat analysis to evaluate the food habits and potential impacts of coyotes (Canis latrans) on white-tailed deer (Odocoileus virginianus) populations in Georgia's Piedmont physiographic region. From March 2010 - February 2011, we analyzed 146 and 207 coyote scats on Cedar Creek (CC) and B. F. Grant (BFG) Wildlife Management Areas, respectively. Although separated by only 8 km, habitat composition and therefore prey availability was dissimilar between sites. We assumed small mammal density was greater on BFG than CC because early successional habitat was more common on BFG (28% of...

Relatively low fecundity may be responsible for lower Ruffed Grouse (Bonasa umbellus) populations in the southern Appalachians compared to those in more northern areas of the species ' range. Nutritional stress imposed by poor-quality habitat and greater nest predation have been cited as negative influences on reproduction in the region. We monitored 56 female grouse during the reproductive season in the Appalachian Mountains of North Carolina, 1999 - 2004, to measure reproductive success and evaluate cover used for nesting. Nests (n = 44) were located to determine fate and habitat...

Paddlefish (Polyodon spathula) contribute to recreational fisheries in 14 U.S. states, including Kansas. They are found in six major river basins in southern and eastern Kansas (Arkansas, Kansas, Marais des Cygnes, Missouri, Neosho, and Verdigris) during spring spawning migrations and are thought to persist in four of those (Kansas, Marais des Cygnes, Missouri, and Neosho) throughout the year. However, most data pertaining to paddlefish in Kansas exist in internal documents or institutional knowledge. Desire to best manage Kansas fisheries has resulted in a need to consolidate this...

Crappies (Pomoxis spp.) are popular sportfish, but can be difficult to manage due to erratic recruitment and variable growth. In this study, we document the population dynamics of a white crappie (P. annularis) population in a small impoundment characterized by low predator density and abundant populations of several forage species. White crappies (n=301) were collected by electrofishing in October 2012. Relative abundance as indexed by electrofishing catch per unit effort of crappie was high (103.3 fish h^-1 ± 18.7 SD). A sub-sample was aged (n = 153) and growth was described...

Historical eradication efforts, increasing fishing pressure, and growing anthropogenic impacts have resulted in decreased abundance or extirpation of the alligator gar (Atractosteus spatula) throughout much of its historic distribution. Current population status has prompted states to actively manage stocks; however, efforts are hindered by a lack of data necessary to make informed management decisions. To begin addressing these data needs, we investigated alligator gar population dynamics and exploitation in Choke Canyon Reservoir, Texas. A total of 754 fish (total length [TL] range, 678...

Relatively few studies have been conducted for white bass (Morone chrysops) populations in large river impoundments. Our study focused on population characteristics of white bass in Kentucky Lake, a mainstem impoundment of the Tennessee River. A total of 994 fish were collected using electrofishing during April 2006 and 2007 to evaluate age, growth, and mortality. Kentucky Lake white bass exhibited relatively fast growth compared to previously studied populations. Females were already larger than males by age-1 and continued to grow faster than males; both genders were sexually mature by...

Flathead catfish (Pylodictus olivaris) populations were sampled in three northeastern Mississippi reservoirs (Aberdeen, Columbus, and Aliceville) along the Tennessee-Tombigbee Waterway to evaluate stock characteristics. Specifically, data were collected on relative abundance, growth, mortality, recruitment, and size structure. These samples were part of a statewide effort to document current population status in reservoirs and to develop management goals. Sampling was conducted in late summer (July-August) during 2011-2013 using low-frequency electrofishing. All fish 250 mm total length...

Reclaimed surface mines present an opportunity to provide large tracts of habitat for northern bobwhite (Colinus virginianus). Reclaimed surface mine sites are commonly planted to non-native species, including sericea lespedeza (Lespedeza cuneata) and tall fescue (Schedonorus arundinaceus), which can inhibit growth of more desirable plant species and limit favorable structure for bobwhite. There have been no studies documenting how bobwhites use various vegetation types common to reclaimed surface mine land. Habitat use studies can provide information on selected vegetation types on these...

Interest in hunting wild turkeys (Meleagris gallopavo) continues to increase, and agencies are challenged with balancing hunter access and activity with management of sustainable turkey populations. Understanding turkey hunter behavior, particularly on public lands, would greatly assist agencies with achieving this balance. We used GPS to track the movements of wild turkey hunters during spring hunting seasons of 2012 and 2013. We used 151 hunter track logs on the 1440-ha southern tract of the Tunica Hills Wildlife Management Area (WMA) located in West Feliciana Parish, Louisiana, to...

As a surrogate species for Strategic Habitat Conservation, the mottled duck (Anas fulgivula) is an indicator species to coastal marsh health and function. Currently, biologists have a relatively poor understanding of regional mottled duck movements. We outfitted adult female mottled ducks with solar satellite transmitters during summer 2009-2011. Movement patterns were measured among years and phenology, in relation to available habitat at the landscape level, and in association to potential disturbance. Movement distances were measured in ArcGIS and then evaluated using analysis of...
