Freshwater and Coastal Ecology

A new study aims to collect information on sturgeon temporal and spatial distribution to inform offshore wind energy and sand leasing operations.

USGS is conducting research to better understand biology, behavior, and survival of juvenile fishes that travel between fresh and saltwater to complete their lifecycles. Migratory fishes as such as herring and shad are vital components in riverine and coastal ecosystems, transporting food and nutrients between fresh rivers and the ocean. They are also an important forage fish for predators in...

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.

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).

Stream ecosystems support vital resources that may be jeopardized by climate change and climate stressors such as drought.

Issue: The Chesapeake Bay Watershed (CBW) is experiencing effects of climate (warming temperatures and shifting precipitation patterns) and land-use/land-cover (LULC; transition from forest or agriculture to developed lands) change, and these trends are likely to continue under future scenarios of warming and population growth. Stream biodiversity may be vulnerable to ongoing and future climate...

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.

Issue: Climate change is warming streams and rivers of the Chesapeake Bay watershed, and this is a critical concern for fisheries management and conservation. To address this issue, the Chesapeake Bay Program (CBP) recently identified four actions: • address the threats of climate change in all aspects of the partnership’s work; • prioritize communities, working lands, and most vulnerable habitats...

There is a growing and urgent need to develop and implement innovative strategies to research, monitor, and manage freshwater resources as societal demands escalate simultaneously with climate-driven changes in water availability.

Issue: The Chesapeake Bay Program partners are striving to improve habitat conditions for recreational fisheries and other native fishes in the Bay and its watershed. While national fish habitat assessments have been conducted, resource managers need more local information to focus restoration and protection efforts in Chesapeake Bay watershed. Conducting the fish-habitat assessments are...

Collaboration between the world-class expertise of USGS scientists, the Atlantic States Marine Fisheries Commission’s Science Program, and state and federal fishery agencies demonstrates the power of partnerships to solve seemingly-insurmountable problems in sustainable and cooperative management of Atlantic coastal fisheries.

Issue: Stream ecosystems are affected by a complex set of interacting terrestrial and aquatic stressors. With many streams experiencing degraded conditions that often correspond with increased anthropogenic activities, an important outcome of the Chesapeake Bay Program is to improve stream health. The USGS is conducting research to better understand the complex factors affecting stream health...
