BackTundra Be Dammed: Beaver Colonization of the Arctic

Snowmelt is occurring, which is reducing permafrost and creating ideal habitat conditions for beavers. Beaver populations are now in competition with native ptarmigans. Tape et. al. suggest that beaver ranges are expanding rapidly in the Alaskan arctic.
