Habitat Selection by Collared Peccaries in Trans-pecos Texas

ry and home range are compatible and used interchangeably in most literature on collared peccaries (Sowls, 1997). Although collared peccaries are relatively abundant in the TransPecos region, only 2 published studies on population ecology have been conducted. Bissonette (1978) investigated influence of temperature extremes on collared peccary behavior in Big Bend National Park, Texas. In all seasons, collared peccary herds bedded during temperature extremes, whether day or night, and were most active at intermediate temperatures. Research using radio telemetry has been conducted to determine home ranges of collared peccaries in Arizona and south Texas, but not in Trans-Pecos Texas. Bissonette (1982) also observed collared peccary herds at Big Bend National Park investigating herd size, home range, behavior, and group dynamics utilizing visual observation in lieu of radio tracking. These observations were limited to 2 lower el-
