Changing Arctic Ecosystems-Measuring and forecasting the response of Alaska's terrestrial ecosystem to a warming climate [More info]
Combining genetic data with current and predicted climate scenarios, we are modeling the predicted future distributions of wildlife populations in the Arctic and identifying key environmental variables that determine important animal habitat.
Changing Arctic ecosystems-Research to understand and project changes in marine and terrestrial ecosystems of the Arctic [More info]
Three themes of ongoing research: forecasting polar bear and walrus population response to changing marine ecosystems; measuring wildlife population changes in the Arctic coastal plain, and wildlife communities in the boreal-Arctic transition zone.
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.
Arctic Refuge coastal plain terrestrial wildlife research summaries [More info]
Updated summaries of research in the Arctic National Wildlife Refuge, Alaska, on caribou, muskoxen, predators (grizzly bears, wolves, golden eagles), polar bears, snow geese and their wildlife habitats with maps of land-cover and vegetation.
PDF The Yukon River Basin Active Layer Network: A cooperative project between the Yukon River Inter-Tribal Watershed Council and the U.S. Geological Survey [More info]
Monitoring soil temperature, soil moisture, air temperature, and overall thickness of the soil and sediment that is above the permafrost, therefore undergoing freeze-thaw cycles. Climate change may affect this active layer; we want to know how it does.
