The modeling approach has helped scientists understand the complex dynamics of avian malaria. The model integrates disease, climate, epidemiology, and population processes to understand how they contribute to disease transmission between mosquitoes and birds and to the impacts on Hawaiian bird species. Use of the model indicates that avian malaria can severely reduce the abundance and limit the distribution of susceptible Hawaiian birds. The model provides important insights into how mosquito dynamics are strongly controlled by temperature and rainfall. The model provides a framework for the evaluation of conservation programs to control disease epidemics and evaluate future risks, such as climate change, as well as identify areas where scientific data is deficient. Finally, this model may be useful for understanding the spread of similar diseases like human malaria, dengue fever, and West Nile virus.

WNS has been rapidly spreading since its discovery in New York State in 2007. Now found in 19 U.S. states and 4 Canadian provinces, the disease is affecting bats in the northeastern United States most severely. Knowing the cause of WNS and how the disease is spread will help decision makers develop management actions to preserve the ecologically and economically valuable bat populations of North America. Insect-eating bats provide ecological pest control services that are estimated to save the agricultural industry $3.7 to $53 billion each year. There is no known cure for white-nose syndrome, and diseases among free-ranging wildlife are difficult to stop once established.

- Black-capped Chickadees and Northwestern Crows in Alaska have the highest rates of gross abnormalities ever documented in wild birds.
- Deformities result from accelerated growth of the beak epidermis. Deformities develop over time and occur only in adult birds.
- The disorder results in severe health consequences and high mortality.
- A geographic expansion of this disorder may be occurring in North America. Despite extensive testing, the cause is currently unknown.
Additional research is currently underway, and the public is encouraged to use the Beak Deformity and Banded Bird Observation Report Web page to report sightings.
This study was funded by the USGS Wildlife: Terrestrial and Endangered Resources Program, U.S. Fish and Wildlife Service Environmental Contaminants Program, the National Science Foundation Graduate Research Fellowship Program, the University of Alaska Foundation Angus Gavin Memorial Bird Research Grant, and the Anchorage Audubon Society.

The USGS Western Fisheries Research Center is providing diagnostic reagents, technical support, and advice to other Federal, tribal, and State biologists that will be testing for ISAV in both wild and hatchery populations of Pacific salmon in Alaska and Washington. Fish viruses commonly move from wild to farmed populations, and the high fish densities in hatcheries could be associated with increased virulence and an ability of viruses to infect or “jump to” new species. If ISAV is confirmed in Pacific salmon on the west coast, next steps would be to test the susceptibility of Pacific salmon and other selected marine fish species to ISAV, assess the ability of salmon to act as carriers and reservoirs for future infections, determine the evolutionary potential of the virus to adapt or increase in virulence, and to analyze the resistance mechanisms in Pacific salmon or other fish species.
This work is funded by the USGS Wildlife: Terrestrial and Endangered Resources and Invasive Species and Contaminants Biology Programs.

Corals are basically modified anemones, which are a group of predatory—and often strikingly pretty—marine organisms related to jellyfish. Corals secrete a calcium carbonate skeleton covered by a thin layer of tissues that form the foundation of coral reefs. Montipora White Syndrome involves loss of tissues from the coral until the underlying white skeleton is exposed. Often, dead corals are then overgrown by algae, leading to permanent reduction in coral reefs and a change in the ecosystem from a coral-dominated to an algae-dominated reef.
The investigation of this recent outbreak has been led by the University of Hawai‘i’s Hawai‘i Institute of Marine Biology in collaboration with University of Hawai’i – West O‘ahu, and the USGS National Wildlife Health Center Honolulu Field Station. The USGS is applying biomedical tools for investigating animal diseases to coral reefs in order to characterize the changes seen in sick corals by looking at the whole coral as well as its cellular structure. As the causes of coral reef diseases are usually unknown, this research will help managers to determine the environmental drivers of these diseases, leading to better intervention and strategies to protect coral reefs and the surrounding marine ecosystems. USGS involvement in this study was funded by the USGS Wildlife: Terrestrial and Endangered Resources Program.

micromole per liter [μM]) could delay the start of cell growth, limit the bacteria’s ability to process nitrate, and alter bacterial community composition. Scientists’ concerns about antibiotic resistance in hospitals and community settings have increased their study of the potential spread of antibiotic-resistant bacteria and the effects of antibiotics in the environment. These results show that exposure to antibiotics could possibly affect the ability of bacteria in soil and aquifer sediments to naturally remove nitrate pollution in groundwater. Too much nitrogen, as nitrate, in groundwater used for drinking water can be harmful to infants. This study was funded by the USGS Toxic Substances Hydrology Program.

Stanford University scientists developed a tool to aid in decisions about the remediation of sediments contaminated with polychlorinated biphenyls (PCBs). The scientists defined the role (or function) of different organisms in the benthic community that live in or on the sediments at the Hunters Point Naval Shipyard Superfund Site, California. Then they compared the total function of benthic communities in PCB-contaminated and uncontaminated sediments. By relating the functional composition of a benthic community and its members to PCB bioavailability induced by in situ remediation, the scientists were able to provide information on the performance of the remediation solution. The ecological model developed by the scientists provides an estimation of the ecosystem recovery expected if the activated-carbon, in situ treatment is effective. This is the first time that the effectiveness of in situ sequestering of PCBs as a remediation solution has been measured in terms of the function and health of the benthic community.
This study was funded by the USGS Toxic Substances Hydrology, National Research, and Priority Ecosystem Science Programs and by the Strategic Environmental Research and Development Program (SERDP - ER-1552).

U.S. Environmental Protection Agency’s drinking-water standard of 30 micrograms per liter (μg/L). USGS scientists determined that:
- Secondary faults that cross under Ralston Creek could act as conduits for or barriers to flow from the mine pool to Ralston Creek.
- While bedrock permeability is low, hydraulic gradients are sufficient to drive groundwater flow from the mine pool to Ralston Creek.
- Although the mine pool is currently about 4 meters below the sealed entrances to the mine, future years with higher than average rainfall could increase the mine pool elevation above the entrances, and contaminated water could seep around the seals.
- The mine workings, mine pool water, mineralized fault zone, and contaminated parts of the alluvial aquifer are all potential sources of dissolved metals to Ralston Creek.

Large amounts of xanthate complexation reagents are used in the milling and extraction process. USGS scientists developed techniques to extract and measure these compounds in environmental samples. Xanthate reagents were not detected in environmental samples. However, trace amounts of xanthate degradation products were found in most sampled locations, including the tailings pond downstream (see photo). Dioctyl sulfosuccinate, a surfactant and process filtering aid, was also found at one mill discharge outlet but not downstream. Dioctyl sulfosuccinate was one of the primary dispersants used in the Deepwater Horizon oil spill in the Gulf of Mexico in 2010. This is the first time that these organic compounds have been detected downstream from lead-zinc mine and milling areas. The information from this study can be used by resource managers to assess the impact of mining operations on aquatic ecosystems. This study was part of a congressionally funded USGS investigation of the effects of mining in the Mark Twain National Forest, Missouri.

U.S. Environmental Protection Agency’s (USEPA) standard for drinking water. This is one of the findings of a recent study by the USGS, in cooperation with the USEPA, to understand how radium is distributed in aquifers across the United States, and to develop a greater understanding of the conditions that control its release from aquifer materials.
Radium is a naturally occurring radioactive element that is produced from the decay of radioactive elements, such as uranium and thorium, and is a known carcinogen.
Almost all wells in the study with radium concentrations greater than the USEPA standard were located in the eastern United States. More importantly, one in five wells in the Mid-Continent and Ozark Plateau Cambro-Ordovician aquifer systems, and in the North Atlantic Coastal Plain aquifer system had combined radium concentrations greater than the USEPA standard. It is important to note that for this study untreated water was sampled, and that concentrations in sampled wells do not necessarily reflect the quality of finished water from wells with treatment systems.
Three common factors were found to be associated with the highest radium concentrations in groundwater: (1) oxygen-poor water, (2) acidic conditions (low pH), and (3) high concentrations of dissolved solids.
This study was funded by the USGS National Water-Quality Assessment (NAWQA) Program and the USEPA Office of Groundwater and Drinking Water.
