Changes in movement, habitat use, and response to human disturbance accompany parturition events in bighorn sheep (Ovis canadensis). [PDF]

open access: goldMov Ecol, 2023
Parturition and the early neonatal period are critical life history stages in ungulates with considerable implications for population growth and persistence.

Impact of Mycoplasma ovipneumoniae on juvenile bighorn sheep (Ovis canadensis) survival in the northern Basin and Range ecosystem. [PDF]

open access: goldPeerJ, 2021
Determining the demographic impacts of wildlife disease is complex because extrinsic and intrinsic drivers of survival, reproduction, body condition, and other factors that may interact with disease vary widely.

Restoration of bighorn sheep: History, successes, and remaining conservation issues

open access: yesFrontiers in Ecology and Evolution, 2023
Mammals are imperiled worldwide, primarily from habitat loss or modification, and exhibit downward trends in their populations and distributions. Likewise, large-bodied herbivores have undergone a collapse in numbers and are at the highest extinction ...

Assessing shared respiratory pathogens between domestic (Ovis aries) and bighorn (Ovis canadensis) sheep; methods for multiplex PCR, amplicon sequencing, and bioinformatics to characterize respiratory flora.

open access: yesPLoS ONE, 2023
Respiratory disease is responsible for dramatic population declines in bighorn sheep (Ovis canadensis), and respiratory pathogen diagnostics contribute to the management of bighorn populations. To create a comprehensive and consistent approach to bighorn

Regional variability in pregnancy and survival rates of Rocky Mountain bighorn sheep

open access: yesEcosphere, 2021
In the Rocky Mountains, bighorn sheep restoration has been only marginally effective; this iconic wilderness species currently exists at a fraction of their historic abundance and often in fragmented and small populations.

Seeing Is Be-Leaving: Perception Informs Migratory Decisions in Sierra Nevada Bighorn Sheep (Ovis canadensis sierrae)

open access: yesFrontiers in Ecology and Evolution, 2022
Seasonal migration is a behavioral response to predictable variation in environmental resources, risks, and conditions. In behaviorally plastic migrants, migration is a conditional strategy that depends, in part, on an individual’s informational state ...

A review of population and landscape level dynamics associated with pneumonia outbreaks in bighorn sheep with implications for land management

open access: yesConservation Science and Practice, 2023
Wildlife conservation necessitates understanding spatiotemporal drivers that facilitate disease outbreaks. Wildlife diseases are influenced by population and landscape level factors which affects host species’ persistence through time.

Complete Mitochondrial Genome Sequence of Bighorn Sheep. [PDF]

open access: yesGenome Announc, 2018
ABSTRACT We report here the complete mitochondrial genome sequence of a Rocky Mountain bighorn sheep ( Ovis canadensis ) in the United States. The circular genome has a size of 16,466 bp and contains 13 protein-coding genes, 22 tRNA genes, and 2 rRNA genes.
