The Chesapeake Bay watershed, or draingage basin, encompasses six states - New York, Pennsylvania, West Virginia, Maryland, Delaware, Virginia, and the District of Columbia. A drainage basin is a giant system of creeks, streams, and rivers that all flow into a common outlet, which in this case is the Chesapeake Bay.

Boise State University Master’s student Kristina Parker uses a syringe to collect blood from a Great Basin rattlesnake (Crotalus oreganus lutosus). The blood’s ribonucleic acid, or RNA will be analyzed to track genetic change in the snake from habitat disturbances. RNA, along with deoxyribonucleic acid – or DNA, are the molecules that carry genetic information.
