Observations on a Cyclic Decline of Lemmings ( Lemmus ) on the Arctic Coast of Alaska during the Spring of 1949

The importance to the biotic community of various species of lemmings in arctic and subarctic regions has long been recognized, but there is little known about the ecology of these mammals. of the two species that occur on the Arctic Slope of Alaska, namely, the collared lemming, Dicrostonyx groenla...
