Food Habits Of Mountain Lions In The Trans-Pecos Region Of Texas, Rosemary A. Heinen, S. Kemble Canon
Food Habits Of Mountain Lions In The Trans-Pecos Region Of Texas, Rosemary A. Heinen, S. Kemble Canon
Great Plains Wildlife Damage Control Workshop Proceedings
Information regarding mountain lion (Felis concolor) food habits is relatively scarce overall, and this is particularly true in the Trans-Pecos region of Texas. Most information currently available is from Big Bend National Park where livestock are excluded and game animals are not actively managed. This study involved the analysis of 32 mountain lion stomachs collected throughout the Trans-Pecos over a 14 month period. Deer (Odocoileus spp.) and javelina (Tayassu tajacu) were the predominate prey species, each occurring in 39% of the stomachs analyzed. Domestic livestock was found in 9% of the total stomachs and non-game …
Predation Of Big Game And Livestock In The Texas Trans-Pecos, S. Kemble Canon
Predation Of Big Game And Livestock In The Texas Trans-Pecos, S. Kemble Canon
Great Plains Wildlife Damage Control Workshop Proceedings
Predation of livestock and big game remains a matter of concern for ranch managers and operators in the Trans-Pecos. Current evidence indicates that mountain lions (Felis concolor), bobcats (Lynx rufus), and coyotes (Canis latrans) are the primary predators involved, although little information is available on bobcats. A gradual shift from sheep to cattle management has resulted in a corresponding decrease in the intensity of predator control efforts for livestock protection. However, potential lease hunting income has renewed predator control efforts for protection of the 3 primary big game species, pronghorn antelope (Antilocapra americana), …

Using Telemetry Equipment For Monitoring Traps And Snares, Thomas D. Halstead, Kenneth S. Gruver, Robert L. Phillips, Richard E. Johnson
Great Plains Wildlife Damage Control Workshop Proceedings
Specialized radio transmitters were developed for use in monitoring large mammal trap and snare activity. Prototype devices were manufactured by 4 wildlife telemetry companies based on specifications we developed in consultation with electronic engineering personnel. Power outputs from individual transmitters ranged from 10 to 100 milliwatts (mw). Range testing in the gently rolling terrain of northeastern Colorado indicated that ground-tracking distances with truck-mounted dual beam antennas exceeded 40 km. Field tests were conducted using transmitters with traps and foot snares set for coyotes (Canis latrans) in California, black bears (Ursus americanus) in Oregon, and mountain lions …
