Contaminants and Environmental Pathways

Living things are intricately connected to each other and to the air, water, and soil that surrounds them. Our research looks at how contaminants move through the environment and living things to understand the chemical and physiological processes and ecological factors that influence exposure and risk in wildlife.

Banding and Encounter Data Requests

Banding and encounter data are available for research purposes. Individual banding data records exist electronically starting in 1960. Pre-1960 banding data are available only for birds that have been encountered. Individual encounter data are available from 1913.

Forests

Our nation’s forests serve many purposes including source of timber, habitat for wildlife, and a place for people to recreate. Our scientists seek to understand how forests can serve all these functions by answering such questions as, “How do forests managed for timber harvest and bird habitat affect the bat populations of the forest?” and “How can hiking trails be designed to minimize impacts...

Climate Change

The impacts of a changing climate on wildlife and associated ecosystems have yet to be fully determined but changes are clearly underway as are a variety of investigations to assess how we can best preserve key resources while effectively managing others.  Using a variety of tools and a combination of studies including adaptive management, long-term monitoring, mathematical modeling, and...

Wetlands

Wetlands play many important roles in the environment including water purification, flood prevention, stabilizing shorelines, and serve as habitat for fish, shellfish, waterfowl and other wildlife.  We work with U.S. Fish & Wildlife Service, National Park Service and other federal and state land managers that are charged with managing our nation’s wetlands to ensure these habitats are...

Avian Influenza

Avian influenza outbreaks can result in significant economic loss, as in 2014-2015 when the Congressional Research Service estimated losses of $3.3 billion dollars from the death and culling of domestic poultry due to an outbreak of this disease.  Patuxent’s avian influenza research seeks to answer such questions as “How far can a bird carrying this virus travel?” and “What influences the...

Coastal & Estuarine

Coastal areas and estuaries contain a variety of habitats that serve many purposes including protecting other lands from flooding and storms, habitats important to commercially harvested fish and shellfish, recreational uses, and habitat for wildlife.

Freshwater

Our nation’s rivers have many uses. People have altered the flow of some rivers through diversions, dams, and water use.  Such changes can affect fish populations and our scientist work to understand these effects by answering such questions as “How is survival of young fish affected by streamflow patterns?” and “How do fish communities respond to changes in water management?”

Chesapeake Bay Projects

The Chesapeake Bay is the nation’s largest estuary and third largest in the world.  It is an important habitat for many species and our science focuses on wetlands and waterbirds. Our scientists address such questions as “How are Chesapeake Bay wetlands responding to sea level rise?” and “How do different shoreline types impact waterbird populations?” and “What can refuge land managers do to...

Wind Energy

Demands for alternative energy are increasing and the number of wind farms, both terrestrial and in the marine environment, while serving great benefit to society, have the potential to impact wildlife populations, particularly birds and bats.  Studies of the spatio-temporal distribution and abundance of birds can identify sensitive and high–use areas in need of protection, not to mention...

Rapid inundation of the southern Florida coastline despite low relative sea-level rise rates during the late-Holocene

Sediment cores from Florida Bay, Everglades National Park were examined to determine ecosystem response to relative sea-level rise (RSLR) over the Holocene. High-resolution multiproxy analysis from four sites show freshwater wetlands transitioned to mangrove environments 4–3.6 ka, followed by estuarine environments 3.4–2.8 ka, during a period of...

Northern forest winters have lost cold, snowy conditions that are important for ecosystems and human communities

Winter is an understudied but key period for the socio-ecological systems of northeastern North American forests. A growing awareness of the importance of the winter season to forest ecosystems and surrounding communities has inspired several decades of research, both across the northern forest and at other mid- and high-latitude ecosystems around...

Individual behaviour and resource use of thermally stressed brook trout Salvelinus fontinalis portend the conservation potential of thermal refugia

Individual aggression and thermal refuge use were monitored in brook trout Salvelinus fontinalis in a controlled laboratory to determine how fish size and personality influence time spent in forage and thermal habitat patches during periods of thermal stress. On average, larger and more exploratory fish initiated more aggressive...

Heat flow in the Western Arctic Ocean (Amerasian Basin)

From 1963 to 1973 the U.S. Geological Survey (USGS) measured heat flow at 356 sites in the Amerasian Basin (Western Arctic Ocean) from a drifting ice island (T-3). The resulting measurements, which are unevenly distributed on Alpha-Mendeleev Ridge (AMR) and in Canada and Nautilus basins, greatly expand available heat flow data for the Arctic Ocean...

A phylogenomic supertree of birds

It has long been appreciated that analyses of genomic data (e.g., whole genome sequencing or sequence capture) have the potential to reveal the tree of life, but it remains challenging to move from sequence data to a clear understanding of evolutionary history, in part due to the computational challenges of phylogenetic estimation using genome-...

A network approach to prioritize conservation efforts for migratory birds

Habitat loss can trigger migration network collapse by isolating migratory birds’ breeding grounds from non-breeding grounds. Theoretically, habitat loss can have vastly different impacts depending on the site’s importance within the migratory corridor. However, migration network connectivity and the impacts of site loss are not completely...

Hydrologic site assessment for passive treatment of groundwater nitrogen with permeable reactive barriers, Cape Cod, Massachusetts

Wastewater disposal associated with rapid population growth and development on Cape Cod, Massachusetts, during the past several decades has resulted in widespread contamination of groundwater with nitrogen. As a result, water quality in many of the streams, lakes, and coastal embayments on Cape Cod is impaired by excess nitrogen. To reduce...
