摘要
Documents the 1st recorded evidence of predation of Dicrostonyx kilangmiutak by Spermophilus parryii, noted at Pearce Point, Northwest Territories. Predation involved some or all of the following: digging lemmings out of burrows, carrying them to temporary ground squirrel burrows, and partial or complete consumption. During 1988, a minimum of 4.5% (6/132) or radiotagged lemmings were killed by squirrels. -from Authors
