Mountain beaver (Aplodontia rufa) behavior: extreme southern limits

The purpose of the present investigation was three-fold: (1) to re-affirm the presence of the mountain beaver in its known southern range (the last report of A. rufa in Sequoia and Kings Canyon National Parks was by Boyer in 1948, (2) to study the behavior of the mountain beaver along the edge of its southern distribution, and (3) to compare aplodontid behavior in its extreme southern distribution with the behavior reported by other authors working nearer the center of its distribution.
