Atlas of relations between climatic parameters and distributions of important trees and shrubs in North America: Revisions for all taxa from the United States and Canada and new taxa from the western United States [More info]
Relations between the geographic distributions of woody plant species and climatic variables in North America. Shows how the spatial distribution of these plants may be expected to change in response to given climatic scenarios.
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 Ecosystemsâ"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 Integrated monitoring of ecological conditions in wetland-upland landscapes [More info]
Landscapes of interwoven wetlands and uplands offer a rich set of ecosystem goods and services. Changes in climate and land use can affect the value of those services. We study these areas to understand how they may be changing.
Polar bear and walrus response to the rapid decline in Arctic sea ice [More info]
The Arctic is warming faster than other regions of the world due to positive climate feedbacks associated with loss of snow and ice. The USGS has modeled the future responses of polar bear and Pacific walrus populations to this environmental change.
PDF Remote sensing of land surface phenology [More info]
Shows how we can use remote sensing to study natural phenomena that vary seasonally but whose timing is affected by both shorter- and longer-term variations in climate or other, similar environmental conditions.
Studying ocean acidification in the Arctic Ocean [More info]
New synoptic data from samples collected in the Arctic Ocean and insights into the patterns and extent of ocean acidification. This foundational geochemical information will help us to understand potential risks to Arctic resources.
