Changing Arctic ecosystems: ecology of loons in a changing Arctic [More info]
Changes in Arctic sea ice and permafrost will likely affect populations of wildlife. Migratory birds such as loons rely on freshwater lakes in the Arctic for nesting and food supply; we are studying how their populations are affected by these changes.
Changing Arctic ecosystems: resilience of caribou to climatic shifts in the Arctic [More info]
Land management agencies need to know how changes in vegetation resulting from climate change may affect wildlife habitat and the food resources that caribou rely on.
Changing Arctic ecosystems: sea ice decline, permafrost thaw, and benefits for geese [More info]
Loss of sea ice has increased ocean wave action, changing coastal habitats. For some geese this has been a positive change, increasing the amount of coastal area that supports vegetation the geese feed on.
Changing Arctic Ecosystems: Updated forecast: Reducing carbon dioxide (CO2) emissions required to improve polar bear outlook [More info]
Polar bears are endangered by reduction in Arctic sea-ice concentration and by reduction in their supply of prey for food. Models shown here indicate anticipated effects on polar bear populations of several climate change scenarios.
Changing Arctic Ecosystems: What is causing the rapid increase of snow geese in northern Alaska? [More info]
High reproductive success and adult survival seem to be the reason. Why do we care? These geese affect other species in the area.
PDF Characterization of Fish Creek, Teton County, Wyoming, 2004-08 [More info]
Preliminary results of hydrologic and biological sampling confirm anecdotal reports that this stream shows unusually high algal growth due to elevated nutrients, probably from groundwater.
Chronic Wasting Disease [More info]
Information on National Wildlife Center research on Chronic Wasting Disease, a disease affecting the nervous system of elk, white-tailed deer and mule deer.
Climatic changes and effect on wild sheep habitat [More info]
Preliminary results indicate significant changes in Dall sheep diet accompanying vegetation changes and upslope retreat of glaciers.
Coastal and Marine Geology Program [More info]
Home page for Coastal and Marine Geology with links to topics of interest (sea level change, erosion, corals, pollution, sonar mapping, and others), Sound Waves monthly newsletter, field centers, regions of interest, and subject search system.
Coastal ecosystem responses to influences from land and sea, coastal and ocean science [More info]
Changes in both the ocean and coastal ecosystems may have negative effects on sea otter populations in the coastal Northwest and Alaska. A study underway will examine these factors and the overall health of sea otter populations.
