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.

A Delaware breed chicken is 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 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.
