Unified Interior Regions

Maryland

Maryland's water supply comes from streams, rivers, groundwater and reservoirs. Many of these systems flow to the Chesapeake Bay, the Nation's largest estuary. This complex ecosystem has been degraded due to the impact of human-population increase. The MD-DC-DE Water Science Center studies the impacts this has on water quality, habitats and biological communities.

DNA Barcoding for Identifying Native Bee Species

The Challenge: Traditionally, bee identification has relied on taxonomic methods centered on descriptions of morphological differences between species. However, for many species, separate keys are required for identifying adult males and females and immature life stages. These keys are commonly unavailable. The lack of distinguishing morphological characters useful for separating closely...

Assessing Toxicogenomics Effects of a Synthetic Androgen on Japanese Quail and the Development of an Avian Vitellogenesis Model

The Challenge: Endocrine active chemicals (EAC) are known to interfere with hormonally regulated physiological processes, thereby affecting signaling in the hypothalamic-pituitary-gonadal-liver (HPGL) axis and commonly resulting in reproductive dysfunction. Computational models that relate hormonal and genomic biomarkers within the HPGL axis to the reproductive cycle and ecologically relevant...

The Role of Japanese Quail in Ecotoxicology

The Challenge: Wild birds are exposed throughout their lives to natural and synthetic chemicals that are present in the environment, many of which interfere with the animal’s physiological and developmental systems. Relative concentrations, routes, frequency, and the environment in which chemical exposure occurs will determine to a large extent the bird’s response. Well-designed avian field...

Identifying the Genetic Basis of Avian Susceptibility to Mercury

The Challenge: Mercury is a highly toxic element found throughout our environment. Although it occurs naturally in some environments, human industrial pollution has greatly increased the amount of mercury and the range of environments in which mercury is found. Recent studies have confirmed clear differences in the sensitivity of various bird species to methylmercury. Because the causes of...

Assessing Adverse Outcomes Associated with Exposure of Birds to Flame Retardants

The Challenge: The use of flame retardants (FRs) as additives in a variety of consumer use products, including plastics, textiles, and electronics, is projected to continue and increase for the foreseeable future. Because of unanticipated environmental problems, some FRs have either been banned, restricted, or are being phased-out and replaced by other new and presumably safer FRs. Regrettably...

Northeast Region Capability Teams

The USGS Northeast Region (NER) began a process of integrating its scientific expertise and technical staff around issues of societal concern. These Regional Capability Teams (CTs) are intended to encourage interdisciplinary scientist-to- scientist collaboration and communication across the NER’s 11 Science Centers and promote the use of best methods on specific science focus areas to produce...

Seabird Research Program

The Seabird Research Program at PWRC is focused on studying the ecology of species present across the Atlantic Coast. This program was a natural progression of PWRC's historic work studying the coastal ecology of wildlife in and around the Chesapeake Bay. We now focus on the three key areas on a variety of species: physiology, avoided bycatch, and movement ecology.

USGS contributes to new STAC report on designing sustainable coastal habitats

The purpose of the Designing Sustainable Coastal Habitats workshop and the approach the workshop steering committee used to bring together scientists, habitat restoration partners, and policy makers to address three goals.  The three workshop goals or themes were to:

USGS works with academic and CBP partners to summarize science on water-quality

Pollution-reducing practices can improve water quality in the Chesapeake Bay and its rivers and streams, according to new research from the Chesapeake Bay Program partnership. In a report released today, a number of case studies show that “best management practices”—including upgrading wastewater treatment plants, lowering vehicle and power plant emissions and reducing runoff from farmland—...

Spatial Capture-Recapture Models to Estimate Abundance and Density of Animal Populations

The Challenge: For decades, capture-recapture methods have been the cornerstone of ecological statistics as applied to population biology.  While capture-recapture has become the standard sampling and analytical framework for the study of population processes (Williams, Nichols & Conroy 2002) it has advanced independent of and remained unconnected to the spatial structure of the population...

Hierarchical Models for Estimation of Population Parameters

The Challenge: Much of wildlife research consists of the description of variation in data. Some of the variation results from spatial and temporal change in populations, while some results from biologically irrelevant sampling variation induced by the process of data collection. Distinguishing relevant from irrelevant variation is the first task of statistical analysis, but the job does not...

Imagine if doctors had time to stop delicate procedures before an earthquake. And if emergency responders had a few extra moments to gear up, airplane landings could be postponed, trains slowed, and people could move to safer locations. Come learn how the USGS and its partners are helping provide critical seconds of notification through an earthquake early warning system in the United States.

Using a geology-based assessment method, the U.S. Geological Survey estimated a mean undiscovered natural gas resource of 3.9 trillion cubic feet and a mean undiscovered natural gas liquids resource of 135 million barrels in continuous accumulations within five East Coast Mesozoic basins, according to a new USGS report.
