Abstract
Changes in numbers and distribution of snowshoe hares (Lepus americanus) on a square-mile study area at Rochester, Alberta, are described. Data spanned a 2-year period, 1962-64, during which the hare population was undergoing a cyclic decline. Analyses of survival, reproduction, and movement indicated that intrapopulation movements rather than differential survival or reproduction were primarily responsible for the observed changes in hare distribution which accompanied the population decrease.
