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.

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.

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.

Fish Passage Design and Analysis at the S.O. Conte Research Laboratory

There are more than 92,000 dams in the United States, of which at least 3% of these produce hydropower. Hydropower projects create renewable energy but also can alter habitats, restrict upstream and downstream movements of fishes and other aquatic organisms, and may stress, injure or kill migrant fishes and other aquatic organisms. In addition, there are more than 5 million culverts and other road...

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.

Terrestrial wildlife and legacy oil mining on National Wildlife Refuges

Amphibian surveys are being conducted on select National Wildlife Refuges with active and/or legacy oil mining to determine species relative distribution and their risk to short- and long-term effects from exposure to crude oil and its byproducts.

Produced water from Marcellus Shale and amphibians

Research biologists at the USGS Eastern Ecological Science Center at the Patuxent Research Refuge are conducting a series of scientific studies on the potential effects of wastewater from hydraulic fracturing activities on terrestrial wildlife. Findings will help in assessing proposals for managing recycling and distribution of large volumes of flowback and produced waters generated by methods of...

Restoring a native fish to Catoctin Mountain Park

Native species conservation is a fundamental purpose of National Parks. Catoctin Mountain Park (CATO) in Maryland supports a prized trout fishery and a healthy community of native fishes, with one exception: native Blue Ridge Sculpin ( Cottus caeruleomentum ) appear to have been extirpated from Big Hunting Creek above Cunningham Falls. Infection by a fungal-like protist Dermocystidium is...

Genetic connectivity among regional populations of red tree corals (Primnoa pacifica) in the North Pacific Ocean

Knowledge of the degree to which populations are connected through larval dispersal is imperative to effective management, yet little is known about larval dispersal capability or population connectivity in Primnoa pacifica , an important habitat forming octocoral on the outer continental shelf and upper slope in the Gulf of Alaska.

Genetic characterization of the clubshell species complex (Pleurobema clava and P. oviforme) for enhanced conservation

The diversity of freshwater mussels (family Unionidae) in the United States is unmatched in the rest of the world, yet this biodiversity is highly vulnerable, with more than 70% of recognized species considered to be either endangered, threatened, or of special concern. Most species inhabit limited ranges and have small (and/or often unknown) dispersal abilities due to reliance on specific host...
