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 ...

Deep Genome Resequencing Reveals Artificial and Natural Selection for Visual Deterioration, Plateau Adaptability and High Prolificacy in Chinese Domestic Sheep

Frontiers in Genetics, 2019
Sheep were one of the earliest domesticated animals. Both artificial and natural selection during domestication has resulted in remarkable changes in behavioral, physiological, and morphological phenotypes; however, the genetic mechanisms underpinning ...

Identification of Ancestry Informative Marker (AIM) Panels to Assess Hybridisation between Feral and Domestic Sheep

Animals, 2020
Hybridisation of wild populations with their domestic counterparts can lead to the loss of wildtype genetic integrity, outbreeding depression, and loss of adaptive features.
