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

Contagious Ecthyma in a Rocky Mountain Bighorn Sheep from Utah

Human-Wildlife Interactions, 2017
In December 2008, near Flaming Gorge Reservoir in northeastern Utah, a 2 ½-year-old male Rocky Mountain bighorn sheep (Ovis canadensis canadensis) was reported in poor body condition with bloody lesions covering the muzzle area. The sheep was euthanized,

Moose Survival and Habitat-Associated Risk of Endoparasites. [PDF]

Ecol Evol
We observed high rates of adult and calf moose survival in New York State, with mortality primarily due to disease associated with giant liver fluke infections. Calf mortality risk increased with increasing use of wetlands, where they can acquire giant liver fluke infections, and decreased with higher amounts of nutritional energy available.

The first complete mitochondrial genomes of snow sheep (Ovis nivicola) and thinhorn sheep (Ovis dalli) and their phylogenetic implications for the genus Ovis

Mitochondrial DNA. Part B. Resources, 2019
In this study, we present the first complete mitochondrial genomes of two species of the genus Ovis – snow sheep (Ovis nivicola) and thinhorn sheep (Ovis dalli).

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.

Osteoporosis and Cranial Asymmetry in a Mountain Sheep (Ovis canadensis) [PDF]

Journal of Wildlife Diseases, 1990
The skull of a mountain sheep (Ovis canadensis cremnobates) exhibiting osteoporosis was recovered from San Diego County, California. This specimen also exhibited lateral asymmetry of the cranium and rostrum, malocclusion of molars, and mandibular asymmetry.

AccelerometerBehavior: R Package for Classifying Ungulate Behaviors Into Three States. [PDF]

Ecol Evol
We provide an R package, AccelerometerBehavior, which facilitates the classification of acceleration data into behavioral states using field‐validated models for ungulates. Our package provides the supervised models so users do not need their own observation data for model training.

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),
