Abstract
We conducted a radiotelemetric study of home-range area and overlap of an herbivorous jerboa (Stylodipus telum) during its spring breeding season in northern Dagestan, Russia. Home ranges of males and females were not significantly different in size. There was little intrasexual overlap in use of space, particularly among females, but home ranges of males and females overlapped extensively. Ranges of any particular male or female typically overlapped those of two to four individuals of the opposite sex, suggesting a promiscuous or polygynous mating system. Individuals used a single day burrow and several shelter burrows. Use of day burrows was exclusive, but shelter burrows often were used by several individuals. When foraging, S. telum used a walking gait and harvested seedheads from low (15–25 cm) grasses; bipedal saltation was used only for escape. No food cache or caching behavior was observed.
