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), …
Canine And Gray Fox Rabies Epizootics In Texas, Keith A. Clark, Pamela J. Wilson
Canine And Gray Fox Rabies Epizootics In Texas, Keith A. Clark, Pamela J. Wilson
Great Plains Wildlife Damage Control Workshop Proceedings
In 1994, 2 ongoing rabies epizootics were declared a state health emergency: canine rabies in South Texas and gray fox (Urocyon cinereoargenteus) rabies in West-Central Texas. Prior to 1988, rabid coyotes (Canis latrans) were infrequently reported in Texas. In 1988, Starr and Hidalgo counties, located in extreme South Texas, experienced an epizootic of canine rabies resulting in 11 laboratory-confirmed cases of canine rabies in domestic dogs (Canis familiaris) and 6 cases in coyotes. By 1991, the epizootic had expanded approximately 160 km north of the United States (US)-Mexico border and included 10 counties. During …
Incidence Of Giardia In Beaver And Nutria In Southeast Texas, Brett G. Dunlap
Incidence Of Giardia In Beaver And Nutria In Southeast Texas, Brett G. Dunlap
Great Plains Wildlife Damage Control Workshop Proceedings
Beaver (Castor canadensis) have long been associated as carriers of Giardia, a flagellated protozoan parasite that inhabits the gastrointestinal tract of its host species. However, very few studies have been conducted on Giardia occurrence in beaver populations of southeastern United States. Nutria (Myocastor coypus) are similar to beavers but have not been researched with regard to Giardia infection and transmission. From October 1992 through September 1993, 100 beaver and 30 nutria were collected from areas throughout southeast Texas as part of wildlife damage management activities. Fecal samples from each individual were examined for the occurrence …
The Oral Rabies Vaccination Project And The Experimental Use Of Raboral V-Rg In The South Texas Canine Rabies Epizootic, M. Gayne Fearneyhough
The Oral Rabies Vaccination Project And The Experimental Use Of Raboral V-Rg In The South Texas Canine Rabies Epizootic, M. Gayne Fearneyhough
Great Plains Wildlife Damage Control Workshop Proceedings
Beginning in October 1988, Texas experienced the onset of an expanding epizootic of canine rabies in far South Texas. That epizootic now involves 18 counties, with 522 laboratory confirmed cases as of December 1994. Approximately 50% of those cases have occurred in coyotes (Canis latrans) and most of the remainder in domestic dogs. Forty-three "spill over" cases have been reported in 7 other species, both wild and domestic. Since 1988, over 1600 people in South Texas have received postexposure rabies treatment due to potential exposure to a rabid animal and 2 human deaths have been attributed to this virus strain. …
