Vector-borne Disease Research

Lyme disease is the most prevalent vector-borne disease in North America, with about 300,000 cases per year in the U.S.  We are studying transmission of the spirochete that causes this disease among wild animals and the blacklegged tick vectors, to determine why Lyme disease is common in the northeast and northern Midwest but rare in the south, even though blacklegged ticks are present in all...

Assessing Amphibian Disease Risk in the Northeast

Disease in amphibian populations can have a range of effects, from devastating declines following introduction of a novel pathogen to recurring breakout events on a landscape. Elucidating mechanisms underlying the effects of diseases on amphibian populations is crucial to help managers make appropriate decisions to achieve management goals for amphibians.

Amphibian Research and Monitoring Initiative (ARMI): Understanding Amphibian Populations in the Northeastern United States

Currently, 90 amphibian species are recognized in the Northeast, including 59 species in the Order Caudata (salamanders) and 31 species in the Order Anura (frogs and toads). Almost half of the amphibians in the Northeast are salamanders within the family Plethodontidae. Amphibians are found in all physiographic regions of the Northeast, from sea level to the heights of the Appalachian,...

Conservation of Rare Vegetation Communities of the Atlantic Coastal Barrier Islands

The Challenge: A synthesis of the role of disturbance, in all of its manifestations, on the establishment and development of the American Holly forest is required to guide future conservation measures. Because many forest fragments have already endured >30 years of chronic deer herbivory, a legitimate question of how much more impact by deer can be tolerated and still conserve the essential...

Development of a Multimetric Index for Integrated Assessment of Salt Marsh Condition in the Northeast Coastal and Barrier Network

Salt marsh ecosystems along all US coastlines have been altered, degraded, and destroyed by human activities, including ditching and drainage of the marsh platform, tidal restrictions, discharge of pollutants, and introduction of invasive species. The National Park Service conducts long-term monitoring of salt marsh vegetation and nekton (fish and free-swimming crustaceans) to provide...

Whooping Crane Restoration

At more than five feet tall with brilliant white plumage, black primary feathers, a red cap, and yellow eyes, the highly endangered Whooping Crane (Grus americana) is one of the most spectacular birds native to North America. In 1942 there were fewer than 20 birds in the flock that migrates from Wood Buffalo National Park in Canada to Aransas National Wildlife Refuge in Texas. An...

Integrating Estuarine Water-Quality Data in Northeastern National Parks

Estuaries worldwide are threatened by nutrient over-enrichment from watershed development. USGS led development of a regional protocol to monitor estuarine nutrient status in northeastern coastal National Parks. Synthesis and reporting of monitoring results at local and regional scales allows park managers to identify changing nutrient loads and susceptibility to eutrophication.

Variation in Stable Isotope Ratios of Eelgrass to Detect Trends in Estuarine Nutrient Status

Seagrasses are among the most productive ecosystems on the planet. Worldwide losses of this important habitat have been caused by water quality degradation association with watershed development. Improved approaches to detect threats of nutrient enrichment are paramount to seagrass conservation.

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.

A three-pipe problem: Dealing with complexity to halt amphibian declines

Natural resource managers are increasingly faced with threats to managed ecosystems that are largely outside of their control. Examples include land development, climate change, invasive species, and emerging infectious diseases. All of these are characterized by large uncertainties in timing, magnitude, and effects on species. In many cases, the...

The pathogenesis of H7 highly pathogenic avian influenza viruses in Lesser Scaup (Aythya affinis)

Waterfowl are the natural hosts of avian influenza virus (AIV), and through migration spread the virus worldwide. Most AIVs carried by wild waterfowl are low pathogenic strains; however, Goose/Guangdong/1996 lineage clade 2.3.4.4 H5 highly pathogenic (HP) AIV now appears to be endemic in wild birds in much of the Eastern Hemisphere. Most research...

Knowing your limits: Estimating range boundaries and co-occurrence zones for two competing plethodontid salamanders

Understanding threats to species persistence requires knowledge of where species currently occur. We explore methods for estimating two important facets of species distributions, namely where the range limit occurs and how species interactions structure distributions. Accurate understanding of range limits is crucial for predicting range dynamics...

Context matters: Using reinforcement learning to develop human-readable, state-dependent outbreak response policies

The number of all possible epidemics of a given infectious disease that could occur on a given landscape is large for systems of real-world complexity. Furthermore, there is no guarantee that the control actions that are optimal, on average, over all possible epidemics are also best for each possible epidemic. Reinforcement learning (RL) has been...
