Alabama is host to a variety of freshwater species, many of which are critically imperiled. USGS and partners focus conservation activities in high priority watersheds throughout the state.
Current tools for detection of Burmese pythons in South Florida have resulted in low detection rates. Environmental DNA - eDNA - has shown to be effective at detecting these invasive snakes, and can help to determine range limits for the species, information that is critical for management and control efforts.
To better understand coastal response to sea-level rise, USGS is monitoring coastal wetland sediment elevations along Florida's east coast.
Researchers at NOROCK and their partners used thermal cameras at the Grizzly and Wolf Discovery Center in Montana to assess the amount of heat lost under a range of environmental conditions with and without hair. These methods help scientists better understand how mange operates in wild wolves throughout the Greater...
There is an urgent need to consider more aggressive and direct interventions for conservation of freshwater fishes threatened by invasive species, habitat loss, and climate change. Conservation introduction - moving species to areas outside their previous range, where conditions are predicted to be more suitable - is one type of translocation strategy that fisheries managers can use to...
Coral reefs around the world are exposed to a number of environmental contaminants. USGS researchers investigate the issue of contamination on the reefs around the U.S. Virgin Islands.
In the last twenty years, an extraordinary number of fungal and fungal-like diseases have caused some of the most severe die-offs and extinctions ever observed in wild species.
We fund complex, often multi-year, research efforts on priority topics (themes) identified by the National Park Service (NPS) Inventory and Monitoring Program. Our efforts complement the Natural Resources Preservation Project (NRPP), which focuses on funding short-term, tactical research to meet natural resource management needs identified by NPS.
We facilitate public understanding of science and environmental change to build support for science and proactive adaptation to environmental change.
Researchers sample water, soil or air to look for presence of Environmental DNA (eDNA), genetic material shed from living or once live organisms whose presence is difficult to detect under traditional sampling methods.
The Adaptive Management process offers a unique mix of management and science to "learn from doing" and decrease uncertainty over time.
Long-term persistence of spent lead shot in tundra wetlands
We seeded experimental plots with number 4 lead pellets and sampled these plots for 10 years to assess the settlement rate of pellets in tundra wetland types commonly used by foraging waterfowl. After 10 years, about 10% of pellets remained within 6 cm of the surface, but >50% remained within 10 cm. We predict that spent lead pellets will...Flint, Paul L.; Schamber, Jason L.
Divergent movements of walrus and sea ice in the Nothern Bering Sea
The Pacific walrus Odobenus rosmarus divergens is a large Arctic pinniped of the Chukchi and Bering Seas. Reductions of sea ice projected to occur in the Arctic by mid-century raise concerns for conservation of the Pacific walrus. To understand the significance of sea ice loss to the viability of walruses, it would be useful to better understand...Jay, Chadwick V.; Udevitz, Mark S.; Kwok, Ron; Fischbach, Anthony S.; Douglas, David C.
GPS tracking devices reveal foraging strategies of black-legged kittiwakes
The Black-legged Kittiwake Rissa tridactyla is the most abundant gull species in the world, but some populations have declined in recent years, apparently due to food shortage. Kittiwakes are surface feeders and thus can compensate for low food availability only by increasing their foraging range and/or devoting more time to foraging. The species...Kotzerka, Jana; Garthe, Stefan; Hatch, Scott A.
Catalogue of polar bear (Ursus maritimus) maternal den locations in the Beaufort Sea and neighboring regions, Alaska, 1910-2010
This report presents data on the approximate locations and methods of discovery of 392 polar bear (Ursus maritimus) maternal dens found in the Beaufort Sea and neighboring regions between 1910 and 2010 that are archived by the U.S. Geological Survey, Alaska Science Center, Anchorage, Alaska. A description of data collection methods, biases...Durner, George M.; Fischbach, Anthony S.; Amstrup, Steven C.; Douglas, David C.
Epizootic of beak deformities among wild birds in Alaska: An emerging disease in North America?
The sudden appearance of a large cluster of animals with gross abnormalities may signal a significant change in an ecosystem. We describe an unusual concentration of beak deformities that appear to have arisen rapidly within Alaska and now extend southward along the Pacific Coast. In Alaska we have documented 2,160 Black-capped Chickadees (Poecile...Handel, Colleen M.; Pajot, Lisa M.; Matsuoka, Steven M.; Van Hemert, Caroline; Terenzi, John; Talbot, Sandra L.; Mulcahy, Daniel M.; Meteyer, Carol U.; Trust, Kimberly A.
Effectiveness of Wildlife Underpasses and Fencing to Reduce Wildlife–Vehicle Collisions
Transportation planners are increasingly incorporating roadway design features to mitigate impacts of highways on wildlife and to increase driver safety. We used camera and track surveys to evaluate wildlife use before and after construction of 3 wildlife underpasses and associated fencing on a new section of United States Highway 64 in Washington...McCollister, Matthew F.
Reproductive Ecology and Habitat Use of Pacific Black Scoters (Melanitta nigra americana) Nesting on the Yukon-Kuskokwim Delta, Alaska
Abundance indices of Black Scoters (Melanitta nigra. americana) breeding in Alaska indicate a long-term population decline without obvious cause (s). However, few life history data are available for the species in North America. In 2001–2004, information was collected on nesting habitat and reproductive parameters (i.e. components of productivity...Schamber, Jason L.
Development of monitoring protocols to detect change in rocky intertidal communities of Glacier Bay National Park and Preserve
Glacier Bay National Park and Preserve in southeastern Alaska includes extensive coastlines representing a major proportion of all coastlines held by the National Park Service. The marine plants and invertebrates that occupy intertidal shores form highly productive communities that are ecologically important to a number of vertebrate and...Irvine, Gail V.
Framework for ecological monitoring on lands of Alaska National Wildlife Refuges and their partners
National Wildlife Refuges in Alaska and throughout the U.S. have begun developing a spatially comprehensive monitoring program to inform management decisions, and to provide data to broader research projects. In an era of unprecedented rates of climate change, monitoring is essential to detecting, understanding, communicating and mitigating...Woodward, Andrea; Beever, Erik A.
Seasonal meso- and microhabitat selection by the northern snakehead (Channa argus) in the Potomac river system
The northern snakehead (Channa argus) is a large piscivorous fish that is invasive in eastern Europe and has recently been introduced in North America. We examined the seasonal habitat selection at meso- and microhabitat scales using radio-telemetry to increase understanding of the ecology of this species, which will help to inform...Lapointe, N.W.R.; Thorson, J.T.; Angermeier, P.L.
U.S. Geological Survey (USGS), Western Region: Coastal ecosystem responses to influences from land and sea, Coastal and Ocean Science
Sea otters and the nearshore ecosystems they inhabit-from highly urbanized California to relatively pristine Alaska-are the focus of a new multidisciplinary study by scientists with the U.S. Geological Survey (USGS) and a suite of international, academic and government collaborators. The Coastal Ecosystem Responses to Influences from Land and Sea...Bodkin, James L.
Individual growth and reproductive behavior in a newly established population of northern snakehead (Channa argus), Potomac River, USA
Northern snakehead (Channa argus) were first found in the Potomac River in 2004. In 2007, we documented feeding and reproductive behavior to better understand how this species is performing in this novel environment. From April to October, we used electrofishing surveys to collect data on growth, condition, and gonad weight of adult fish. Growth...Landis, Andrew M. Gascho; Lapointe, Nicolas W.
