Do Early-Life Conditions Drive Variation in Senescence of Female Bighorn Sheep? [PDF]
Front Cell Dev Biol, 2021 The rate of senescence may vary among individuals of a species according to individual life histories and environmental conditions. According to the principle of allocation, changes in mortality driven by environmental conditions influence how organisms ...

California Fish and Wildlife Journal, 2023 Bighorn sheep (Ovis canadensis) habitat frequently is geographically discontinuous and the metapopulation model fits this species well. Consequently, extinction-colonization dynamics are important and need to be monitored.

Exposure of bighorn sheep to domestic goats colonized with Mycoplasma ovipneumoniae induces sub-lethal pneumonia. [PDF]
PLoS ONE, 2017 Bronchopneumonia is a population limiting disease of bighorn sheep (Ovis canadensis) that has been associated with contact with domestic Caprinae. The disease is polymicrobial but is initiated by Mycoplasma ovipneumoniae, which is commonly carried by ...

Potential disease agents in domestic goats and relevance to bighorn sheep (Ovis canadensis) management. [PDF]
PLoS ONE, 2017 Domestic goats are raised for meat, milk and hair production, in herds for rangeland weed control, and as pack animals. Domestic sheep, goats and wild bighorn sheep are all susceptible to a multifactorial pneumonia.

Comparing contemporary models to traditional indices to estimate abundance of desert bighorn sheep
Journal of Wildlife Management, 2023 Aerial surveys for large ungulates produce count data that often underrepresent the number of animals. Errors in count data can lead to erroneous estimates of abundance if they are not addressed.

Local extinction and unintentional rewilding of bighorn sheep (Ovis canadensis) on a desert island. [PDF]
PLoS ONE, 2014 Bighorn sheep (Ovis canadensis) were not known to live on Tiburón Island, the largest island in the Gulf of California and Mexico, prior to the surprisingly successful introduction of 20 individuals as a conservation measure in 1975.

Variation in diet of desert bighorn sheep around parturition: Tradeoffs associated with parturition
Frontiers in Ecology and Evolution, 2023 Selection of forage and habitats is driven by nutritional needs of individuals. Some species may sacrifice nutritional quality of forage for the mother in favor of safety of offspring (risk-averse strategy), immediately following parturition.

Epizootic pneumonia of bighorn sheep following experimental exposure to Mycoplasma ovipneumoniae. [PDF]
PLoS ONE, 2014 Bronchopneumonia is a population limiting disease of bighorn sheep (Ovis canadensis). The cause of this disease has been a subject of debate. Leukotoxin expressing Mannheimia haemolytica and Bibersteinia trehalosi produce acute pneumonia after ...

CONDUCTIVE HEARING LOSS IN BIGHORN SHEEP [PDF]
Journal of Wildlife Diseases, 1995 In January 1993 we simulated a conductive hearing loss in three Mexican bighorn sheep (Ovis canadensis mexicana) by placing bone wax or saline solution in their ear canals. Our objective was to test whether lesions of the external auditory canal caused by psoroptic mites (Psoroptes ovis) may lead to conductive hearing loss in bighorn sheep. We assessed
