305b Groundwater Quality Monitoring in New York

Relatively little data describing the quality of groundwater in New York State exist, yet groundwater is used as a source of drinking water by approximately one quarter of the population of the state. The objective of the 305(b) groundwater quality monitoring project is to quantify and report on ambient groundwater quality from bedrock and glacial-drift aquifers in upstate New York.

National Assessment of Coastal Vulnerability to Sea Level Rise

The original national coastal vulnerability index (CVI) assessment was motivated by expected accelerated sea-level rise (SLR) and the uncertainty in the response of the coastline to SLR. This research was conducted between 1999 and 2001, and is currently being updated using new data sources and methodology. This original study was part of the ...

Trout with “blacktail” associated with whirling disease

Whirling disease, caused by the myxosporean parasite Myxobolus cerebralis was identified as an emerging pathogen of trout in the intermountain west region of the U.S. in the early 1990’s.   Investigators here worked collaboratively with others to further our understanding of this disease and its impacts on trout and other salmonid fishes.

Invasive pathogens

Streamside salamanders such as this one are susceptible to invasive fungal pathogens of the genus Batrachochytrium.  Two types of emerging fungal agents, B. dendrobatidis and B. salamandrivorans have been identified as serious risks to our amphibian populations.

Estimating connectivity of hard clam (Mercenaria mercenaria) and eastern oyster (Crassostrea virginica) larvae in Barnegat Bay

Many marine organisms have a well-known adult sessile stage. Unfortunately, our lack of knowledge regarding their larval transient stage hinders our understanding of their basic ecology and connectivity. Larvae can have swimming behavior that influences their transport within the marine environment. Understanding the larval stage provides insight...

Managing the trifecta of disease, climate, and contaminants: Searching for robust choices under multiple sources of uncertainty

Wood frogs, like other amphibian species worldwide, are experiencing population declines due to multiple stressors. In the northeastern United States, wood frog declines are thought to result from a reduction in successful metamorphosis in part due to climate change, disease (specifically ranavirus) and contaminant exposure. The presence of...

Early genetic outcomes of American black bear reintroductions in the Central Appalachians, USA

Habitat loss and overexploitation extirpated American black bears (Ursus americanus) from most of the Central Appalachians, USA, by the early twentieth century. To attempt to restore bears to the southwestern portion of this region, 2 reintroductions that used small founder groups (n = 27 and 55 bears), but different release methods (hard versus...

Spatially explicit network analysis reveals multi-species annual cycle movement patterns of sea ducks

Conservation of long-distance migratory species poses unique challenges. Migratory connectivity—that is, the extent to which groupings of individuals at breeding sites are maintained in wintering areas—is frequently used to evaluate population structure and assess use of key habitat areas. However, for species with complex or variable annual-cycle...

Evidence for a role of arginine vasotocin (AVT) receptors in the gill during salinity acclimation by a euryhaline teleost fish

The neurohypophysial nonapeptide arginine vasotocin (AVT) plays a role in regulation of osmotic balance in teleost fishes, but its mechanisms of action are not fully understood. Recently, is was discovered that nonapeptide receptors differentiated into V1a-type, several V2-type, and two isotocin (IT) receptor paralogs in teleost fishes, and it...

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...
