Unusual Beaver, Castor canadensis, Dams in Central Yukon
Keywords:Beaver, Castor canadensis, dam construction, Yukon
AbstractNorth American Beavers (Castor canadensis) are remarkable for their ability to build dams and modify their habitat. Dams are typically made of the boles and branches of trees and large shrubs, and reinforced with mud and rocks. Here, we report two unusual Beaver dams in central Yukon, Canada, that are made primarily of medium-sized rocks. This observation points to the adaptability of Beavers in using available materials to build their dams.
