The BSL-3 complex at the USGS Eastern Ecological Science Center was purpose-built to serve our Nation’s needs. This facility has special engineering and design features for maintaining a safe environment when working with diseases that spread in the air. The facility is unusual in that it is designed to also be used for work with aquatic animals

Blotchy bass syndrome (BBS) is the presence of hyperpigmentation (melanosis) on the external surface of black basses. This condition has received increased attention from anglers and resource managers in recent years and is a popular topic of discussion and reporting on angling websites and blogging platforms.

The USGS Native Bee Inventory and Monitoring Lab designs and develops large and small scale surveys for native bees. As part of this work we also develop identification tools and keys for native bee species. One aspect of creating those tools is creating accurate and detailed pictures of native bees and the plants and insects they interact with.
