Matt Burgess from the USGS National Uncrewed Systems Office pilots a drone over research ponds at the Eastern Ecological Science Center as part of a methods development campaign to examine how multiple types of remote sensors may be used to map and identify algae, including those that lead to Harmful Algal Blooms.

Blue Ridge sculpin (Cottus caeruleomentum) are being acclimated to the water temperature and chemistry of the Experimental Stream Laboratory at the Eastern Ecological Science Center in West Virginia. Fish from this study will be used to restore an extirpated population in Catoctin Mountain Park in Maryland.

Wheat seeds with (A) and without (B) neonicotinoid coating. Wheat seeds with neonicotinoid coating were fed to eight Delaware chickens in summer 2022 as part of a controlled experiment to better determine what effect (if any) neonicotinoid-treated seeds have on birds that consume them.

These Delaware breed chickens are part of a controlled experiment to better determine what effect (if any) neonicotinoid-treated seeds have on birds that consume them. Results from this experiment may inform future field research on the potential sublethal effects of agricultural practices on Washington state sage grouse, a state-endangered species.

USGS sturgeon biologist, Micah Kieffer, surgically implants telemetry tag in a juvenile sturgeon captured (and later released) during a survey in the Lower Kennebec River

USGS research fishery biologist Micah Kieffer sutures an adult Atlantic sturgeon after implanting an acoustic transmitter in its abdomen as part of efforts by USGS Eastern Ecological Science Center and partners to better understand sturgeon movements in the Gulf of Maine. This project was funded by the U.S.

USGS technician Zach Kelly inserts a Passive Integrated Transponder (PIT) tag into an anesthetized Blue Ridge sculpin at the EESC Experimental Stream Laboratory. The PIT tag will enable researchers to monitor fish growth, survival, and movement after their release.
