Nocturnal Bird Migration through the Central Appalachians

The Challenge: Concerns have arisen about the potential impacts of wind power development in the Appalachians on migrating birds, creating a critical need for information on their distribution and flight characteristics as they pass through the region. This study focuses on the spatial and temporal distribution of nocturnally migrating birds in the Central Appalachians (MD, VA, WV). The...

Vulnerability Assessment of Available Habitat for Wintering Black Ducks within the Refuge System in the Chesapeake Bay

American black duck (Anas rubripes) utilize inland and tidal freshwater and brackish marshes throughout the Chesapeake Bay and are considered to be an indicator species of the ecosystem’s health. Thus, conserving and increasing black duck habitats will subsequently benefit the general health of the bay. The goal of this study was to create a mechanistic model to determine the amount...

Endocrine Active Effects on Turtle Embryonic Development

The Challenge: Emerging contaminants may be in part responsible for recent endocrine disruption observed in fish in the Chesapeake Bay watershed. Endocrine active compounds implicated in the decline of fish populations may affect other wildlife as well. There are 6 species of turtles and 5 of snakes living within the main-stem and tidal areas of the Bay. As poikilotherms, reptiles are...

The Eastern Box Turtle at USGS Patuxent Wildlife Research Center, MD

The Challenge: Once common to forest and backyard habitats, the eastern box turtle (Terrapene carolina) has declined sharply. Threats to box turtles include loss and fragmentation of their habitat, road mortality, and commercial taking for the international pet trade. Researchers at the USGS Patuxent Wildlife Research Center have 70 years of records on a turtle population located within a 12...

National Park Service Visitor Spending Effects

The National Park Service (NPS) manages the Nation’s most iconic destinations that attract millions of visitors from across the Nation and around the world. Trip-related spending by NPS visitors generates and supports a considerable amount of economic activity within park gateway communities. USGS economists collaborate with the National Park Service social science program to estimate NPS...

North American Waterfowl Management Plan

The ultimate success of North American Waterfowl Management Plan (NAWMP) depends on maintaining relevance to stakeholders and society. In order to be relevant, a first step is to better understand what people value in regard to waterfowl and their habitats. Without this information, NAWMP population, habitat, and people objectives may not reflect stakeholder and societal values; and management...

Understanding Coastal Change

Scientists perform a range of studies that document, assess, and model coastal change, risk, and vulnerability. Studies include historical shoreline change, the geologic structure and history of coastal regions, sediment supply and transport, sea-level rise, and how extreme storm events affect rates and impacts of coastal change.

Geologic Hazards and Catastrophic Events

We study the distribution and hazard potential of coastal and submarine events such as earthquakes and submarine landslides and associated tsunami potential, hurricane induced coastal inundation, extreme storms, sea-level rise and oil and gas spills. We also model development to help evaluate and forecast coastal hazard probability and occurrence.
