摘要: Pronghorn (Antilocapra americana) vary in spatial organization. A literature review revealed that males occupied undefended home ranges 12 populations and maintained territories 11 populations. Low-productivity habitats high or low population density could preclude territoriality. Using activity budgets, interaction rates, home-range overlap, male social organization was described for a translocated pronghorn central California compared with of another studied at Sheldon National Wildlife Refuge, Nevada, to determine if were organized differently. Interaction rates highest during spring, decreased summer, then increased late summer coincident the rut. Home-range overlap ranged from 0 85% averaged 30.6%; small amounts resulted geographical features rather than behavioral interactions. Males joined groups females fawns summer; few behavior patterns associated territoriality observed. Mal...
