Systematic Approach to Understanding Tree Swallow Health in the Great Lakes Region—Science to Inform Restoration

Four papers by U.S. Geological Survey (USGS) scientists document tree swallow (Tachycineta bicolor) chemical exposure, physiological responses, and reproductive success in the Great Lakes region. These studies were designed to understand if there are health threats to swallows from contaminant exposure, and to provide resource managers with information about the actual as opposed to the perceived...

Selected Pharmaceuticals Not Likely to Persist in Wild Fish: Results of Uptake and Elimination Testing

Laboratory study shows that both uptake and elimination of selected pharmaceuticals within bluegill tissues is rapid indicating that persistence in bluegills in the environment is likely to be low except in those fish that reside downstream from a consistent, substantial, contaminant source.
