Eastern Ecological Science Center

In 2020, the USGS Patuxent Wildlife Research Center and Leetown Science Center merged to create the Eastern Ecological Science Center (EESC). Our goals are to align our scientific capabilities with the most pressing conservation and management challenges; establish an engaged workforce that fosters high relationship trust with employees, partners and the public.

Bedrock depth influences spatial patterns of summer baseflow, temperature and flow disconnection for mountainous headwater streams

In mountain headwater streams, the quality and resilience of summer cold-water habitat is generally regulated by stream discharge, longitudinal stream channel connectivity and groundwater exchange. These critical hydrologic processes are thought to be influenced by the stream corridor bedrock contact depth (sediment thickness), a parameter often inferred from sparse hillslope borehole information,

Museum genomics provide evidence for persistent genetic differentiation in a threatened seabird species in the Western Atlantic

Connectivity among wildlife populations facilitates exchange of genetic material between groups. Changes to historical connectivity patterns resulting from anthropogenic activities can therefore have negative consequences for genetic diversity, particularly for small or isolated populations. DNA obtained from museum specimens can enable direct comparison of temporal changes in connectivity among p

Rapid implementation of high-frequency wastewater surveillance of SARS-CoV-2

There have been over 507 million cases of COVID-19, the disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), resulting in 6 million deaths globally. Wastewater surveillance has emerged as a valuable tool in understanding SARS-CoV-2 burden in communities. The National Wastewater Surveillance System (NWSS) partnered with the United States Geological Survey (USGS) to im

Advancing Risk Modeling for Highly Pathogenic Avian Influenza

Southeast Asia has long been the epicenter of AIV emergence. However, as demonstrated by H5NX, these viruses can quickly reach global spread and have significant impacts on poultry production and human health. We have two ongoing efforts funded by the National Science Foundation to help improve our understanding of AIV emergence, spread, and transmission in today’s rapidly changing landscape.

Red Knot Migration and Population Ecology

Eastern Ecological Science Center biologists are studying migration and population ecology of the rufa red knot, a bird species that is dependent on horseshoe crab eggs to complete its trans-hemispheric migration. The birds' spring migration is timed with spawning of horseshoe crabs because the eggs are the perfect food for a migrating red knot.
