Production, Behavior, and Survival of Juvenile Shad and River Herring
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...
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.
Population Monitoring and Removal Strategies for Blue Catfish (Ictalurus furcatus) in Chesapeake Bay
USGS is helping with the design of a population survey and developing mathematical models to assess potential activities to manage the population of invasive blue catfish ( Ictalurus furcatus) in the Chesapeake Bay. This research will help managers determine the cost and feasibility of approaches to control this invasive species.
Osprey (Pandion haliaetus) Population and the Availability of Menhaden (Brevoortia tyrannus) as Their Food Source in Chesapeake Bay: Historical and Present-day Comparison
USGS is collaborating with many biologists in analysis of data on osprey ( Pandion haliaetus) and their prey (menhaden, Brevoortia tyrannus, and other species of fish) in the middle and lower Chesapeake Bay and its tributaries. The data compiled and collected will help determine if a lack of menhaden or other environmental factors are affecting osprey reproductive success in portions of the...
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.
Integrating Science and Management to Assist with the Response to Stony Coral Tissue Loss Disease
A USGS multi-disciplinary team will use laboratory and modeling approaches to investigate the cause of stony coral tissue loss disease.
Brook trout vulnerability to drought: eastern component of USGS national integrated ecohydrological research
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.
Assessing the habitat conditions to support freshwater fisheries in the Chesapeake Watershed
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...
Eastern Ecological Science Center partnership with Atlantic States Marine Fisheries Commission
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.
Mapping riverine habitats of the Delaware River using bathymetric LiDAR
Ecosystem management and assessment of rivers requires detailed data on bathymetry before estimates of aquatic habitats can be determined. However, mapping bathymetry in shallow rivers is challenging due to river depth limitations for watercraft.
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.
Integrating Habitat and Harvest Management for Northern Pintails
The Challenge: Several blue-ribbon panels have challenged the waterfowl management world to recognize the linkages between the two primary management frameworks: harvest management under the Migratory Bird Treaty Act, and habitat management under the North American Waterfowl Management Plan. Because these two frameworks seek to manage the same populations, there needs to be better coordination, in...
