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.

Explainable machine learning improves interpretability in the predictive modeling of biological stream conditions in the Chesapeake Bay Watershed, USA

Anthropogenic alterations have resulted in widespread degradation of stream conditions. To aid in stream restoration and management, baseline estimates of conditions and improved explanation of factors driving their degradation are needed. We used random forests to model biological conditions using a benthic macroinvertebrate index of biotic integrity for small, non-tidal streams (upstream area ≤2

Genome resequencing clarifies phylogeny and reveals patterns of selection in the toxicogenomics model Pimephales promelas

BackgroundThe fathead minnow (Pimephales promelas) is a model species for toxicological research. A high-quality genome reference sequence is available, and genomic methods are increasingly used in toxicological studies of the species. However, phylogenetic relationships within the genus remain incompletely known and little population-genomic data are available for fathead minnow despite the poten

Range-wide sources of variation in reproductive rates of northern spotted owls

We conducted a range-wide investigation of the dynamics of site level reproductive rate of northern spotted owls using survey data from 11 study areas across the sub-species geographic range collected during 1993–2018. Our analytical approach accounted for imperfect detection of owl pairs and misclassification of successful reproduction (i.e., at least one young fledged) and contributed further in

Wastewater Surveillance

September 2021, wastewater sampling for COVID-19 was carried out by USGS across six states as part of the National Wastewater Surveillance System. Results of this work include the development of an effective high-frequency sampling approach to support rapid wastewater-based epidemiology and provided important and timely data to the Centers for Disease Control (CDC).

2020 CARES Act

The Coronavirus Aid, Relief and Economic Security Act (CARES Act) was signed into law on March 27th, 2020, to aid response efforts and ease the economic impact of COVID-19. The Department of the Interior received funds to “prevent, prepare for, and response to coronavirus, domestically or internationally including, “biosurveillance of wildlife and environmental persistence studies.” The USGS...
