Ecology and Social Behavior of the Collared Peccary in Big Bend National Park, Texas

摘要

A behavioral and ecological study was conducted on collared peccaries (Dicotyles tajacu) for 23 months in Big Bend National Park, Texas. The purpose of the study was to elucidate some of the relationships of resource structure, quality, and availability to social behavior and organization of peccaries. Field work attempted to: (1) establish a quantitative basis for peccary behavior, (2) determine the pattern of resource use by peccaries, (3) assess the effect of habitat type on subgroup composition and stability, and (4) determine the precise relationship between range quality, measured by the relative abundance of preferred forage species, and territorial group size and home range (group-range) size.
