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...
The Black Rail (Laterallus jamaicensis) is the most secretive of the secretive marsh birds and one of the least understood bird species in North America. The Eastern Black Rail (L. j. jamaicensis) is listed as endangered in five states along the Atlantic Coast and is under review for federal listing. Historical population size was likely in the tens of thousands but is now believed to be in the hundreds or low thousands (Watts 2016). Within the United States, Eastern Black Rails breed within three general geographic areas within the United States - the Atlantic Coast, the Gulf Coast and the Midwest-Great Plains. The Atlantic Coast has generally been considered to support the largest breeding population throughout...
