Abstract
Home range size estimates in a population of Peromyscus leucopus changed as a function of sample size, reaching an asymptote at nine captures. Despite the short life-span of this species in the wild, a trapping regime that greatly increases the likelihood of obtaining at least nine captures can be devised, although the probability is extremely sensitive to the number of trap nights per session. Home ranges appear not to shift during the time required to obtain sufficient sample sizes.
