Dr. Vicki Blazer and Dr. Heather Walsh extracting plasma from smallmouth bass sampled from the South Branch Potomac River.  The plasma will be used for the quantification of vitellogenin (an egg yolk precursor protein used as a biomarker of endocrine disruption in male fish).    

A female Common Eider is being held by graduate student Tori Mezebish while the duck is being anesthetized for surgery to implant a small satellite transmitter to track the duck during subsequent breeding years.

Dr. Glenn Olsen is performing surgery on a female Common Eider to implant a small satellite tracking device in the duck. The surgery is done under sterile conditions and general anesthetic.

The U.S. Fish and Wildlife Service considers the Appalachian grizzled skipper (Pyrgus wyandot). The small number of known colonies, the small number of individuals per colony, and the lack of information on the genetic relationships among the colonies, populations, and metapopulations render the Appalachian grizzled skipper vulnerable to extinction.

The mysterious case of the Appalachian Rusty-patched Bumble Bee (Bombus affinis) holdouts. There are no more RPBB's in most of North American, people have looked, it's not really a question of overlooking them any longer, they are just all gone. Fingers point to a set of introduced European bumble bee pathogens.

An annual count has been conducted at Patuxent Research Refuge every year since 1941, when the refuge consisted of only the Central and South Tracts. In the last few years, bird watchers have regularly observed Lincoln’s Sparrows during the Christmas Bird Count at Patuxent Research Refuge.

The Eastern Ecological Science Center's Leetown Research facility has multiple quarter-acre and half-acre research ponds to use for fish rearing and other outdoor laboratory applications.  Here we are cleaning sediment and debris from the "kettle" collection area of the ponds to keep them ready for use.
