Paranasal Sinus Masses of Rocky Mountain Bighorn Sheep (Ovis canadensis canadensis) [PDF]

Veterinary Pathology, 2010
This article describes 10 cases of paranasal sinus masses in Rocky Mountain bighorn sheep ( Ovis canadensis canadensis). Among 21 bighorns that were examined from 11 herds in Colorado, 10 individuals (48%) from 4 herds (36%) had masses arising from the paranasal sinuses. Affected animals included 9 of 17 females (53%) and 1 of 4 males (25%), ranging in

Genetic and Environmental Indicators of Climate Change Vulnerability for Desert Bighorn Sheep

Frontiers in Ecology and Evolution, 2020
Assessments of organisms’ vulnerability to potential climatic shifts are increasingly common. Such assessments are often conducted at the species level and focused primarily on the magnitude of anticipated climate change (i.e., climate exposure). However,

Heterogeneity in risk‐sensitive allocation of somatic reserves in a long‐lived mammal

Ecosphere, 2022
Food quality and availability, when combined with energetic demands in seasonal environments, shape resource acquisition and allocation by animals and hold consequences for life‐history strategies.

GEOGRAPHIC ANALYSIS OF PATHOGEN EXPOSURE IN BIGHORN SHEEP (OVIS CANADENSIS) [PDF]

Journal of Wildlife Diseases, 1994
Antibody responses were examined among 998 bighorn sheep (Ovis canadensis) in California (USA) to determine spatial patterns of pathogen exposure. Using a shifting frame analysis, a specific geographic region was delineated that contained bighorn sheep with higher (P < 0.05) levels of multiple exposure (antibodies detected against > or = two pathogens),

Behavior‐specific habitat models as a tool to inform ungulate restoration

Ecosphere, 2021
Across North America, many ungulate species that experienced historic population declines and range contractions are now broadly distributed across their native ranges after the implementation of successful restoration programs.
