Mammals

Our science portfolio includes the study and management of mammal populations, which can require the use of methods and analysis that incorporate the difficulty in detecting them – picture how hard it is to count and identify bats at dusk or estimate the number of mountain lions in an area.

Fish

The health of freshwater fish populations is tied closely to competing demands and uses for this resource. Patuxent scientists are applying mark-recapture science and other methods developed for the adapative management of waterfowl to help manage freshwater fish and their habitats.

Pollinators

Our research on pollinators is focused on how to identify, count, and assess populations of bees and butterflies. We are currently developing extensive tools for identifying and monitoring native bees, and for how to estimate numbers of local populations that inhabit fragile ecosystems.

Nutrient Loads from the Upper Connecticut River Watershed

River-borne nutrients, especially nitrogen, contribute to water-quality degradation in Long Island Sound. The Connecticut River is the largest tributary to the Sound, and quantification of nutrient loads from the three upper States in the watershed, as well as the State of Connecticut, is essential for prioritizing efforts to improve the Sound’s water quality.

Land Stewardship and Environmental Contaminants

Department of Interior manages millions of acres on behalf of the American people. The need to manage these natural resources can include activities such as pest and weed control, which may involve the application of chemicals.  Our research helps land managers know the potential hazards of these chemicals and identifies any possible actions to reduce unwanted effects on wildlife.

Industrial Chemicals and Processes

Industry, including manufacturing, chemical processing, and energy development and extraction, is a critical part of our nation’s economy. Chemicals such as lubricants, coolants, flame retardants, adhesives and others are widely used in industrial processes. And sometimes these chemicals are encountered by wildlife as spills, wastes, and byproducts in the environment.  Our research seeks to...

Agricultural Activities and Pesticides

Agriculture plays an important role in our economy and many kinds of chemicals are used for the production, transportation, storage, and manufacturing of food. Agricultural areas attract a variety of wildlife and our scientists provide the needed research to understand potential hazards to wildlife from these agricultural chemicals and how unintentionally exposed animals may be affected.

Natural hazards and mineral commodity supply: Quantifying risk of earthquake disruption to South American copper supply

Mineral resources, and their mining and enrichment operations, are not equally distributed across Earth. The concentration of mineral supply in certain regions, owing to the geology or geography of the mineral resource, raises the level of risk related to supply disruption. Where mineral production coincides with areas prone to natural hazards,...

Long-term (37 years) impacts of low-head dams on freshwater shrimp habitat connectivity in northeastern Puerto Rico

Freshwater migratory shrimp in Puerto Rico depend on watershed connectivity, from stream headwaters to the ocean, to complete their life cycle. Moreover, shrimp populations in different watersheds are known to be connected in an island-wide metapopulation. However, low-head dams paired with water intakes on streams draining the El Yunque National...

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...
