Passage, Migration and Critical Habitat of Atlantic (Acipenser oxyrhinchus oxyrhinchus) and Shortnose (Acipenser brevirostrum) Sturgeons in New England Waters
USGS scientists are studying the passage, migration and critical habitat of the Atlantic ( Acipenser oxyrhinchus oxyrhinchus ) and shortnose ( Acipenser brevirostrum ) sturgeon in New England waters to provide managers with population-specific details upon which effective steps can be taken to protect these endangered species.
Supporting Interstate Conservation of Atlantic Sturgeon (Acipenser o. oxyrinchus) Using Genetics, Telemetry, and Side-scan Sonar
USGS scientists are using innovative combinations of telemetry, genetics, and side-scan Sonar to support conservation of endangered Atlantic sturgeon ( Acipenser o. oxyrinchus) .
Using Multiple Indicators to Assess Stream Condition in the Chesapeake Bay
USGS is working with federal, state and local partners to develop multiple assessments of stream and river conditions in non-tidal areas of the Chesapeake Bay watershed. These assessments will help managers preserve stream health and improve biological conditions in impaired streams as the human population and climate continue to change in this region.
Sustaining Horseshoe Crabs and Supporting Migratory Shorebirds in the Delaware Bay
USGS is developing predictive models to inform sustainable harvest of horseshoe crabs ( Limulus polyphemus) in Delaware Bay to help managers make decisions to support needs of people and shorebirds including rufa red knot ( Calidris canutus rufa ).
Advancing the Environmental DNA Toolkit for Ecosystem Monitoring and Management
The emerging field of Environmental DNA (eDNA) analysis allows characterization of species presence and community biodiversity by identifying trace amounts of genetic material left behind as organisms move through their environments. EESC scientists have been using eDNA technologies to detect native and rare species and as community biomonitoring tools.
Using Pollinator Environmental DNA to Assess the Ecological Resilience of America’s Grasslands
Scientists from six USGS science centers are collaborating with USDA, university, and Tribal partners, and Department of the Interior land managers, to assess the status of pollinator communities and the distribution of species of conservation concern using environmental DNA. These methods will be used to improve assessments of habitat quality and pollinator responses to restoration, including...

Sturgeon Occurrence and Behavior in the Outer Continental Shelf
A new study aims to collect information on sturgeon temporal and spatial distribution to inform offshore wind energy and sand leasing operations.
Northeast Amphibian Research and Monitoring Initiative
The U.S. Geological Survey’s Eastern Ecological Science Center is home to the Northeast Amphibian Research and Monitoring Initiative (NEARMI), one of 7 ARMI regions across the United States. NEARMI works on public lands in thirteen states from Maine to Virginia, including many National Parks and National Wildlife Refuges.
Dysbiosis, immunomodulation, and health effects of agricultural pesticides in wild prairie grouse
Agrochemical pollution poses a severe threat to biodiversity. Agrochemicals can detrimentally affect wildlife growth, development, survival, reproduction, and immune responses, which facilitates emergence and spread of infectious diseases that may cause unusually high mortality. Animal microbiota plays a fundamental role in host’s food detoxification and defense against pathogens, regulates...
Development of Next Generation Techniques of fecal samples collected from nestling cactus wren
Coastal cactus wren populations have declined in southern California over the last three decades. In San Diego County, this decline has been especially noticeable in the Otay area, which in 2014 supported 14 territories on conserved lands. In the past, there were 25-53 active territories reported for this same area, with the highest estimate in 1992. There is also concern the number of active...
Developing and testing eDNA markers for the Federally endangered dwarf wedgemussel, Alasmidonta heterodon and other key freshwater mussel species
Dwarf wedgemussel is a federally endangered freshwater mussel with a historic range spanning the Atlantic coast. However, populations have dramatically declines over the last 30 years. Therefore, knowledge of current population distribution and abundance is critical to resource managers in order to monitor the species over time and to guide recovery actions. Manual survey efforts (snorkel or scuba...
Pre-listing Science Support in the Northeast
We are working closely with multiple partners to provide updated information, model potential outcomes, and identify key uncertainties relevant to amphibian and reptile species proposed for listing in the northeast US. We also provide timely science to partners to assist in recovery of listed species, which may involve field research, data analysis, or decision support.
