Traceback of the Psoroptes outbreak in British Columbian bighorn sheep (Ovis Canadensis) [PDF]
International Journal for Parasitology: Parasites and Wildlife, 2021 Psoroptes are a non-burrowing, ectoparasitic, mange-causing mite that has been documented in American bighorn sheep populations throughout the 19th and 20th centuries; however, it was not seen on Canadian bighorn sheep until 2006.

Genomic association with pathogen carriage in bighorn sheep (Ovis canadensis) [PDF]
Ecology and Evolution, 2021 Genetic composition can influence host susceptibility to, and transmission of, pathogens, with potential population‐level consequences. In bighorn sheep (Ovis canadensis), pneumonia epidemics caused by Mycoplasma ovipneumoniae have been associated with ...

Role of carriers in the transmission of pneumonia in bighorn sheep (Ovis canadensis) [PDF]
Biology Open, 2016 In the absence of livestock contact, recurring lamb mortality in bighorn sheep (Ovis canadensis) populations previously exposed to pneumonia indicates the likely presence of carriers of pneumonia-causing pathogens, and possibly inadequate maternally ...

Development of a high-density sub-species-specific targeted SNP assay for Rocky Mountain bighorn sheep (Ovis canadensis canadensis) [PDF]
PeerJDue to their abundance and relative ease of genotyping, single nucleotide polymorphisms (SNPs) are a commonly used molecular marker for contemporary population genetic and genomic studies. A high-density and cost-effective way to type SNP loci is Allegro

An individual-based modelling approach to estimate landscape connectivity for bighorn sheep (Ovis canadensis) [PDF]
PeerJ, 2016 Background. Preserving connectivity, or the ability of a landscape to support species movement, is among the most commonly recommended strategies to reduce the negative effects of climate change and human land use development on species.

Production of Cloned Bighorn Sheep Embryos Using ISCNT via HMC from Domestic Sheep Oocytes Treated with Resveratrol During IVM [PDF]
AnimalsThe aim of this study was to treat sheep oocytes with resveratrol during in vitro maturation (IVM) and use them as cytoplasts in ISCNT via handmade cloning (HMC), evaluating the effect of resveratrol on the in vitro development of cloned Mexican bighorn ...
