Researcher Julia Ersan prepares to release hoary bat
USGS WERC researcher Julia Ersan gets prepared to release a hoary bat (Lasiurus cinereus) after capture and examination. USGS researchers are conducting multiple projects to learn about the ecology of Western bats, including long distance migrants like the hoary bat.

Mallard Duckling from Suisun Marsh
This mallard duckling was captured in Suisun Marsh. USGS scientists are weighing, measuring and banding waterfowl to understand how they are using the marsh and for capture-recapture data.

Unionoid mussel
The Missouri Department of Conservation (MDC) is frequently queried regarding the general status of endangered and threatened mussels in Missouri, a question that will remain incompletely answered until a sufficiently rigorous and comprehensive assessment and monitoring framework is implemented in Missouri.
