Sympatry Increases Predation Risk for an Endangered Ungulate. [PDF]

Ecol Evol
We characterized predation risk for Peninsular bighorn sheep and southern mule deer across their ranges to understand how topography, habitat, forage, and prey habitat suitability affect where pumas are likely to predate both species. The presence of the second ungulate species increased predation risk for both species but had the greatest effect on ...

MAXILLARY CANINES IN BIGHORN SHEEP

The Southwestern Naturalist, 2006
Abstract Bighorn sheep (Ovis canadensis) occasionally have small, procumbent maxillary canines that do not penetrate the gums. However, the frequency of these vestigial teeth is only 3%. We collected 25 skulls from an isolated and indigenous population of bighorn sheep in the Silver Bell Mountains, Arizona.

Twinning in Bighorn Sheep

The Journal of Wildlife Management, 1966
Twelve bighorn ewes (Ovis canadensis), killed by vehicular traffic in southern British Columbia, were examined for pregnancy; 11 were pregnant, 4 of them were carrying twins. The absence of twins among bighorn sheep frequently has been noted by biologists recording their field observations. A recent author (Woodgerd, W. 1964.

Bluetongue in the Desert Bighorn Sheep

The Journal of Wildlife Management, 1967
A young desert bighorn ram (Ovis canadensis) approximately 8 months old was found ill in its natural habitat. Inoculation of a suspension of its lung tissue into domestic sheep resulted in lesions typical of bluetongue disease. Serological studies confirmed the diagnosis.

FATAL PNEUMONIA OF BIGHORN SHEEP FOLLOWING ASSOCIATION WITH DOMESTIC SHEEP

Journal of Wildlife Diseases, 1982
During 1979-1980 acute fibrinopurulent bronchopneumonia resulted in high mortality or total loss of herds of bighorn sheep (Ovis canadensis) in California and Washington. Contact with domestic sheep occurred shortly before the onset of disease in each case.
