A tale of two coasts: tidal marsh persistence with changing climate and sea-level rise- Karen Thorne

The overall goal of this project is to improve our understanding of the combined effects of inundation, due to sea-level rise and storm surges, and other climate factor on tidal marsh physical and biological processes to provide guidance to natural resource managers to reduce these threats and increase resilience.

Collecting Ecological Data and Models of Living Shoreline Restoration Projects

Developing effective living shoreline restoration projects that can withstand hurricanes and storms requires a better understanding of how restoration structures reduce the impact of wave and current energy on marsh edges in estuaries and bays. Without this knowledge, existing living shoreline projects and adaptive management measures are more likely to fail, decreasing the possibility for...

Flow Modeling at Dam Removal Sites Associated with Hurricane Sandy Resiliency Efforts

The purpose of this work is to better understand the effects of dam removal on local hydraulics, fish passage, and flooding. This study is part of a larger effort to monitor ecological resilience changes at nine Hurricane Sandy coastal resiliency aquatic connectivity restoration projects. It will contribute crucial knowledge that will be used to improve aquatic connectivity system cost-...

Bird Banding Laboratory

The Bird Banding Laboratory (BBL) is an integrated scientific program established in 1920 supporting the collection, archiving, management and dissemination of information from banded and marked birds in North America.  This information is used to monitor the status and trends of resident and migratory bird populations. Because birds are good indicators of the health of the environment, the...

Heavy-Mineral Sand Resources in the Southeastern U.S.

We are assessing the extent of industrial mineral resources hosted by heavy-mineral sands in the coastal plain of the southeastern United States. “Heavy-mineral sands" (HMS) is a term commonly used in industry and geologic literature to describe layered sediments deposited in coastal environments that contain dense (“heavy") minerals of economic value. The heavy minerals extracted from these...

Disease Resistance of Wildlife Species: how the immune system evolves and adapts

The Challenge: In an era when emerging infectious diseases are steadily increasing, human populations are exposed to virulent new pathogens.  Insight into the human system can be gained from understanding the variety of immune adaptations of wildlife species.  The vertebrate immune system is not static.  Rather, it involves in response to the environment.

Genomic and Behavioral Effects of the Neonicotinoid Imidacloprid in Birds Exposed Through Pesticide-Coated Seeds

The Challenge: Neonicotinoid pesticides act as agonists of nicotinic acetylcholine receptors (nAChRs) and are designed to be lethal to insects while theoretically posing little to no threat to vertebrates. The perceived safety of neonicotinoids has led to a sharp increase in their use in the United States and globally, since they were first introduced in 1994. The use of the neonicotinoid...

U.S. Geological Survey (USGS) Science Summary—The Role of Storms on Bank Erosion Rates and Sediment Transport in Urban Areas

Sediment is a major pollutant degrading aquatic ecosystems in the Chesapeake Bay watershed. The USGS is conducting studies to determine the relative importance of streambank erosion to other sediment sources, such as upland erosion, in both agricultural and urban areas. The information is necessary so resource managers can focus on the types, and locations, of practices that will be most...
