Population connectivity patterns of genetic diversity, immune responses, and exposure to infectious pneumonia in a metapopulation of desert bighorn sheep.

Journal of Animal Ecology, 2023
Habitat fragmentation is an important driver of biodiversity loss and can be remediated through management actions aimed at maintenance of natural connectivity in metapopulations.

ABORTION AND NEONATAL MORTALITY DUE TO TOXOPLASMA GONDII IN BIGHORN SHEEP (OVIS CANADENSIS)

Journal of Wildlife Diseases, 2023
: Low lamb recruitment can be an obstacle to bighorn sheep (Ovis canadensis) conservation and restoration. Causes of abortion and neonate loss in bighorn sheep, which may affect recruitment, are poorly understood.

Testing the match–mismatch hypothesis in bighorn sheep in the context of climate change

Global Change Biology, 2021
In species with long gestation, females commit to reproduction several months before parturition. If cues driving conception date are uncoupled from spring conditions, parturition could be mistimed. Mismatch may increase with global change if the rate of

Previously Unrecognized Exposure of Desert Bighorn Sheep (Ovis canadensis nelsoni) to Mycoplasma ovipneumoniae in the California Mojave Desert

Journal of Wildlife Diseases, 2021
: A 2013 outbreak of respiratory disease in bighorn sheep from California's Mojave Desert metapopulation caused high mortality in at least one population.

Pasteurellaceae from Colorado Bighorn Sheep Herds

Journal of Wildlife Diseases, 2011
We compared phenotypic and genotypic characterizations of 88 Pasteurellaceae isolates from bighorn sheep (Ovis canadensis) in the course of exploring epizootiologic relationships. Based on our observations, adopting contemporary taxonomic conventions and using molecular methods to detect and compare Pasteurellaceae may help improve understanding of ...

Fire-driven landscape heterogeneity shapes habitat selection of bighorn sheep

Journal of Mammalogy, 2021
Patterns in disturbance severity and time since fire can drive landscape heterogeneity that is critical to conservation; however, there is limited understanding of how wildlife interact with the spatial–temporal complexities of disturbance outcomes and ...

Bighorn sheep optimization algorithm: a novel and efficient approach for wireless sensor network coverage optimization

Physica Scripta
Wireless Sensor Network (WSN) coverage optimization is crucial for maximizing monitoring capability with limited resources. This paper proposes a novel Bighorn Sheep Optimization Algorithm (BSOA), inspired by the social behaviors of bighorn sheep.

PATHOLOGY OF CHRONIC MYCOPLASMA OVIPNEUMONIAE CARRIERS IN A DECLINING BIGHORN SHEEP (OVIS CANADENSIS) POPULATION

Journal of Wildlife Diseases
: Bighorn sheep (Ovis canadensis) across North America commonly experience population-limiting epizootics of respiratory disease. Although many cases of bighorn sheep pneumonia are polymicrobial, Mycoplasma ovipneumoniae is most frequently associated ...

Multi‐locus sequence typing indicates multiple strains of Mycoplasma in desert bighorn sheep and aoudad in Texas

Journal of Wildlife Management
Epizootic events of pneumonia, presumably caused by Mycoplasma ovipneumoniae, in bighorn sheep (Ovis canadensis) have been observed in the western United States and Canada. Until recently, it was thought that populations of Mexican (O. c.
