Year-round water management for desert bighorn sheep corresponds with visits by predators not bighorn sheep. [PDF]

PLoS ONE, 2020
Managing water (e.g., catchments) to increase the abundance and distribution of game is popular in arid regions, especially throughout the southwest United States, where biologists often manage water year-round for desert bighorn sheep (Ovis canadensis ...

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.

Disease Ecology of a Low-Virulence Mycoplasma ovipneumoniae Strain in a Free-Ranging Desert Bighorn Sheep Population [PDF]

Animals, 2022
Infectious pneumonia associated with the bacterial pathogen Mycoplasma ovipneumoniae is an impediment to bighorn sheep (Ovis canadensis) population recovery throughout western North America, yet the full range of M.

Incorporating foray behavior into models estimating contact risk between bighorn sheep and areas occupied by domestic sheep

Wildlife Society Bulletin, 2014
Respiratory disease epidemics are considered a primary factor limiting bighorn sheep (Ovis canadensis) populations in most of the western United States. Diverse sources of evidence indicate that domestic sheep harbor pathogens that cause fatal pneumonia ...

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

Frontiers 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 ...

Distinct host–pathogen and microbiome responses of aoudad (Ammotragus lervia) and bighorn sheep (Ovis canadensis) following exposure to Mycoplasma ovipneumoniae with or without co-exposure to leukotoxigenic Pasteurellaceae [PDF]

BMC Veterinary Research
Background Pathogens can shape their host communities over various timescales. The potential role of host–pathogen co-evolution in driving contemporary shifts in disease ecology is becoming increasingly important as host species emerge and persist ...
