Tundra Be Dammed: Beaver Colonization of the Arctic
By B.M. Jones | C.D. Arp | G. Grosse | I. Nitze | K.D. Tape
For this article, the researchers examined sites with evidence of new beaver pond colonization in 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.
