  Beavers may be new to the Arctic, but they’re already leaving their mark.  The industrious rodents are expanding their range as a result of environmental change, pushing their way north into permafrost and tundra landscapes. Their arrival carries many consequences for subsistence users. Creeks that once supported reliable fishing are now beaver-dammed. Fish and […]

The climate-driven spread of beaver ponds in Alaska’s Arctic accelerates the effects of a warming environment by causing pond-adjacent permafrost to thaw and by increasing the amount of liquid water present during winter. Those are the key findings of the first comprehensive, on-the-ground assessment of the northward migration of beavers. The research was led by […]
