Pictured is a federally endangered Shenandoah salamander (Plethodon shenandoah). NEARMI has been working for years to study this species in hopes to protect it from extinction. To learn more about the research being done on this species, visit https://www.usgs.gov/nearmi. 

Black basses (Micropterus spp) are enigmatic North American sportfishes that support the most economically valuable freshwater sport fishery in the United States and serve as keystone predators within aquatic ecosystems.

Micah Kieffer, EESC sturgeon biologist and a member of NOAA's sturgeon recovery network, returns to the S.O. Conte Research Laboratory with a young adult Atlantic sturgeon that was found on the shore in Reverse, Massachusetts in February of 2022.  Fish is scheduled for necropsy in the days to come.

With the willing help, and creative problem solving skills of roughly 20 volunteers throughout the day,  these two structures emerged. Bolts were tightened down, people quickly figured out what needed to happen and by the end of the day two Hoop House structures were up and almost ready for the clear sheeting that will cover them.

A field at the Bee Lab is leveled with gravel in preparation for the Hoop House area. Disassembled Hoop House parts were laid out on the leveled gravel to be sorted, lined up and put together. Roughly 20 volunteers showed up to help align and set the Hoops in to place.

USGS map showing the movement of a lesser scaup infected with highly pathogenic avian influenza (red line) compared to four lesser scaup not infected (maroon, yellow, blue and black lines). Movement was recorded January 23 to 26, 2022. The black dot identifies where the birds were captured and released in Maryland.

This is a long-tailed salamander (Eurycea longicauda), which can be easily identified by its unique pattern and long tail. The tail of the long-tailed salamander can measure up to the twice the length of the body. This species is stream-adapted, meaning that the larvae are fully aquatic and live in streams.
