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...

Modeling the Response of Freshwater Mussels to Changes in Water Temperature, Habitat, and Streamflow
North American freshwater mussels are in serious decline as a result of pollution and habitat destruction from human activities. In addition, many mussel species are living in habitats that push the upper limits of their heat tolerance, which may become problematic as the climate and, as a result, water temperatures warm. As part of this project, we created a set of models to predict how freshwater mussels would respond to climate change effects. Our primary objective was to help federal and state natural resource managers forecast how mussel species will respond to climate change over the next 30 to 50 years, so that managers can develop appropriate adaptation strategies to address these changes. Additionally,...
