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...

This SSP project produced a Final Report and two publications. Carey, C.S., J.W. Jones, R.S. Butler, E.M. Hallerman. 2015. Restoring the endangered oyster mussel (Epioblasma capsaeformis) to the upper Clinch River, Virginia: an evaluation of population restoration techniques. Restoration Ecology. DOI: 10.1111/rec.12195. From 2005 to 2011, the federally endangered freshwater mussel Epioblasma capsaeformis (oyster mussel) was reintroduced at three sites in the upper Clinch River, Virginia, using four release techniques. These release techniques were (1) translocation of adults (site 1, n=1418), (2) release of laboratory-propagated sub-adults (site 1, n=2851), (3) release of 8-week-old laboratory-propagated juveniles...

One of the most diverse freshwater mussel assemblages in the world once occurred in the Cumberland and Tennessee Rivers. Several of these species are now extinct; others linger on as relic, nonreproducing populations, and populations of the remaining species have also declined. Although many factors contributed to the decline of mussels, habitat loss from impoundments and poor water quality in tailwaters have been major causes. Recently, the Tennessee Valley Authority (TVA) initiated a major program to improve water quality in the tailwaters by maintaining minimum flows and by oxygenating discharged water. This program has resulted in significant improvements in water quality. These improvements have resulted in...

This SSP project conducted from FY2002-2006 had several parts: The optimal control model portion which was worked on by Scott Duke Sylvester for his dissertation research. A spore dispersal study conducted by Allison Snow (USGS employee based at the Arthur R. Marshall Loxahatchee NWR) A spore germination study conducted by Erynn Call (USGS employee based at the Arthur R. Marshall Loxahatchee NWR) A user interface for Scott's model done by Gareth Mann and Leonard Pearlstine, University of Florida. An analysis of Lygodium in the refuge from IKONOS data done by Ken Rutchey at South Florida Water Management District. The first and last projects were not funded with SSP funds, but are considered part of the project....

This SSP project resulted in one scientific investigations report A one-dimensional step-backwater model was developed by the U.S. Geological Survey (USGS) in cooperation with the U.S. Fish and Wildlife Service, Pee Dee National Wildlife Refuge, North Carolina, to provide a means for predicting flood-plain inundation. The model was developed for selected reaches of the Pee Dee River, Brown Creek, and Rocky River, using the U.S. Army Corps of Engineers Hydrologic Engineering Center River Analysis System (HEC-RAS) software. Multiple cross sections were defined on each modeled stream, and hydrologic data were collected between August 2011 and August 2013 at selected locations on the Pee Dee River and on its tributaries...

Products from this SSP project consisted of a large amount of GIS data, analysis, and maps. There were shared GIS personnel for FWS served by this SSP project that generated lots of maps and direct services.

This SSP project contributed to production of two reports and two publications. Pallid sturgeon Scaphirhynchus albus were captured from the Atchafalaya River System and implanted with ultrasonic transmitters and tracked with mobile receivers and sentinel (constantly recording) receivers to understand habitat use and movements.

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...
