| Abstract: | Home range use and activity patterns of black-tailed jackrabbits ( Lepus californicus ) in northern Utah were studied using telemetry. Home range sizes ranged from 2 to 3 km 2 and did not differ between sexes or among seasons. Jackrabbits were inactive during daylight, became active at dusk, and remained active throughout the night. Animals often traversed their home ranges in a few hours. During the breeding season, males were more active than females. Jackrabbits were most active during well-lit nights, and high winds decreased jackrabbit activity. |
