Climate-related changes in environmental conditions are challenging rural residents’ ability to traverse the land and access subsistence resources.
Browsing by snowshoe hares and moose have dramatic top-down influences on vegetation composition, successional dynamics, and ecosystem function throughout interior Alaska.
Recent models indicate that lengthening of the snow-free season and associated declines in surface albedo constitutes the largest positive feedback to climate warming in the boreal forest.
Increases in air temperatures and depth of insulating snow cover during winter are accelerating the rate of permafrost thaw. In areas of ice-rich permafrost, widespread thermokarst is having significant consequences for biogeochemical cycling and surface hydrology.
