The Distribution and Dispersal of Pikas: Influences of Behavior and Climate

Explore this paper's citation graph

Summary

Field experiments suggest that when pikas are deprived of the opportunity to retreat to favorable microclimates in rockslides, they are unable to tolerate the high diurnal tempera- tures found at lower elevations, and high environmental temperatures apparently constitute a major stress on dispersing individuals at low altitudes.
