Other Wildlife Diseases

Wildlife diseases are an important stressor to some wildlife species. Patuxent scientists work with birds and amphibians to understand how diseases affect their populations. Our scientists are at work on a broad range of questions to understand wildlife disease.  Our research is working to answer questions like “How might differences in tick behavior influence the risk of Lyme disease for...

Hurricanes

The high winds and storm surge associated with hurricanes impacted coastal wetlands from Virginia to Maine.  Understanding the ecological and geological impacts of hurricanes on coastal wetlands and both resident and migratory wildlife populations is fundamental to helping rebuild and maintain these unique ecosystems.

Sea-level Rise

Acceleration in sea-level rise and changing environmental stressors have important implications for the integrity of coastal wetlands and for efforts to restore and protect the ecosystem services they provide. Federal and state agencies need to make more detailed assessments of how different watersheds and shoreline types might influence an array of ecosystem functions and components and...

New Jersey Water-Transfer Data System (NJWaTr)

The State of New Jersey strives to allocate water resources to meet human demands and ecological needs. NJWaTr is a database system that compiles, stores, and distributes New Jersey’s water use data for research and modeling purposes.  NJWaTr helps officials understand the movement and uses of water throughout the State over time.

Recreation Ecology

Wilderness areas in the United States are preserved for their untrammeled naturalness and opportunities for unconfined recreation. In park and wilderness management, integrating social and resource indicators is essential to meet park mandates that require the protection of both experiential and resource conditions. Recreation ecology examines the effects of recreation on protected area...

Structured Decision Making

The biggest natural resource management challenges include competing views of the value and uses of those resources in society. Patuxent scientists develop methods to manage resources given those competing views under a “structured decision making” (SDM) framework. Our scientists both practice and train others in key SDM skills, such as model development and monitoring design.

Hierarchical Modeling

Hierarchical models, also known as mutl-level and mixed effects models, have advanced the field of population ecology with inferences about population dynamics at broad spatial and temporal scales. The analysis of hierarchical models has been facilitated by recent advances in Bayesian analysis, and computationally intensive techniques such as Markov Chain Monte Carlo (see Mathematical modeling...

Gas Hydrates- Climate and Hydrate Interactions

Breakdown of gas hydrates due to short- or long-term climate change may release methane to the ocean-atmosphere system. Methane that reaches the atmosphere can in turn exacerbate climate warming. Studies of methane hydrate dynamics and methane release on the continental shelf and upper slope in the US Arctic and Atlantic margin are tracking these processes.

Gas Hydrates- Energy

Natural gas production from methane hydrates may someday prove viable. The USGS Gas Hydrate Project takes part in US and international programs to investigate the potential of deepwater marine and permafrost gas hydrates as an energy resource. Long-term production tests are the next step in this research.

Assessing potential effects of highway and urban runoff on receiving streams in total maximum daily load watersheds in Oregon using the stochastic empirical loading and dilution model

The Stochastic Empirical Loading and Dilution Model (SELDM) was developed by the U.S. Geological Survey (USGS) in cooperation with the Federal Highway Administration to simulate stormwater quality. To assess the effects of runoff, SELDM uses a stochastic mass-balance approach to estimate combinations of pre-storm...

Hydrocarbons in upland groundwater, Marcellus Shale Region, Northeastern Pennsylvania and Southern New York, USA

Water samples from 50 domestic wells located <1 km (proximal) and >1 km (distal) from shale-gas wells in upland areas of the Marcellus Shale region were analyzed for chemical, isotopic, and groundwater-age tracers. Uplands were targeted because natural mixing with brine and hydrocarbons from deep formations is less common in those areas...

Carbon dioxide emissions and methane flux from forested wetland soils of the Great Dismal Swamp, USA

The Great Dismal Swamp, a freshwater forested peatland, has accumulated massive amounts of soil carbon since the postglacial period. Logging and draining have severely altered the hydrology and forest composition, leading to drier soils, accelerated oxidation, and vulnerability to disturbance. The once dominant Atlantic white cedar, cypress, and...

Seasonal and spatial variation in the location and reactivity of a nitrate-contaminated groundwater discharge zone in a lakebed

Groundwater discharge delivering anthropogenic N from surrounding watersheds can impact lake nutrient budgets. However, upgradient groundwater processes and changing dynamics in N biogeochemistry at the groundwater-lake interface are complex and difficult to resolve. In this study, hydrograph variations in a groundwater flow-through lake...

Concurrent assessment of epidemiological and operational uncertainties for optimal outbreak control: Ebola as a case study

Determining how to best manage an epidemiological outbreak may be hindered by both epidemiological uncertainty (i.e. about epidemiological processes) and operational uncertainty (i.e. about the effectiveness of candidate interventions). These two uncertainties are rarely addressed concurrently in epidemic studies, impeding decision-making. We...

Begging behavior as an honest signal of need and parent-offspring association during the post-fledging dependency period

Honest signaling mechanisms can function to appropriate care to hungry offspring and avoid misdirected care of unrelated offspring. Begging, the behavior by which offspring solicit food and parental care, may be an honest signaling mechanism for need, as well as association of parents and offspring. Roseate terns (Sterna dougallii) exhibit...

Thin-layer sediment addition to an existing salt marsh to combat sea-level rise and improve endangered species habitat in California, USA

Current tidal marsh elevations and their accretion rates are important predictors of vulnerability to sea-level rise. When tidal marshes are at risk, adaptation measures, such as sediment addition to increase elevations, can be implemented to prevent degradation and loss. In 2016, wildlife managers prescribed a thin-layer sediment addition of...
