Abstract
Liver-trapping at monthly intervals provided data on numbers and dispersion for a western Montana [USA] P. maniculatus poulation. In summer 1971, the population increased 4-fold to a high of about 20 adults/ha. The hypothesis that such increases would be associated with changes in spatial relationships is discussed. Each resident category was dispersed similarly before and after the population increase. Established (known to be present for at least 2 mo.) same-sex adults were evenly spaced while recently appearing adults aggregated among themselves and with established residents. Numbers of established residents remained constant and the numerical increase resulted from large numbers of recent immigrants.Keywords
