No report for this QR project is available at this time. This project initially set out to expose snakeheads and flathead catfish (2 invasive fishes) to electric fields in a controlled laboratory study. This turned out to be not feasible for two reasons. Permits to hold the right species of snakeheads on campus could not be obtained, and flathead catfish of appropriate sizes that had not been previously exposed to electric fields (i.e., not captured by electrofishing) could not be attained. The objectives (and timeline) were revised to focus on food web relations for snakeheads and flathead catfish, specifically: (a) Determine trophic level and sources of prey for northern snakeheads collected from the Potomac...

The overall goal of this SSP project was to evaluate the exposure and toxicological effects of contaminant stressors in the water and sediment of the Clinch River in areas of high mussel decline in Virginia and in areas of high abundance and recruitment in Virginia and Tennessee. The investigation also included an assessment of major tributary streams with varied histories of degradation, recovery and disturbance. The specific objectives of this project were to: 1. Integrate existing data sets on mussel populations, NPDES discharges, mining and other energy permitted activities, pesticide use, and land use. 2. Using passive sampling devices, measure water concentrations of a suite of polar and non-polar organic...

This SSP project resulted in a dissertation: A Dynamic Model of Semipalmated Sandpiper Migration:Implications For Conservation. By Jeffrey Allan Hostetler Abstract I developed a stochastic dynamic programming model of adult female Semipalmated Sandpiper (Calidris pusilla) spring migration for the purpose of adaptive management of wetlands along their migratory route. Semipalmated Sandpipers are small abundant shorebirds that migrate through Merritt Island National Wildlife Refuge, FL, Yawkey Reserve, SC, Pea Island National Wildlife Refuge, NC, and Delaware Bay on their way from the Caribbean and South America to arctic North American breeding grounds. The first three stopover sites mentioned include managed wetlands....

This SSP project resulted in a final report and two publications (Nest occurrence and survival of King Rails in fire-managed coastal marshes in North Carolina and Virginia, King Rail (Rallus elegans) Occupancy and Abundance in Fire Managed Coastal Marshes in North Carolina and Virginia). The project explored this use of Bayesian network modeling using the King Rail as a case study. Although Bayesian network (BN) models have been promoted to the conservation community as models well-suited to support adaptive management strategies, there have been few tests of these claims. To test the value of BNs to support U.S. Fish and Wildlife Service and U.S. Geological Service's Strategic Habitat Conservation approach to...

After being nearly driven to extinction by the combination of human persecution, human-caused habitat change, and subsequent hybridization with coyotes, red wolves (Canis rufus) were rescued from extinction by the establishment of a captive breeding program in 1973. In 1987, red wolves were first released into a coyote-free (Canis latrans) area in northeastern North Carolina. But by the early 1990’s coyotes began colonizing the area, and pairings between red wolves and coyotes were first detected in 1993. In 2000, a program to contain hybridization and introgression by sterilizing coyotes and removing hybrids began. Genetic assignment tests were used to determine which canids were red wolves, hybrids, and coyotes....
