Density of wild prey modulates lynx kill rates on free-ranging domestic sheep. [PDF]

PLoS ONE, 2013
Understanding the factors shaping the dynamics of carnivore-livestock conflicts is vital to facilitate large carnivore conservation in multi-use landscapes.

Identification of selective sweep and associated QTL traits in Iranian Ovis aries and Ovis orientalis populations

Frontiers in Genetics
IntroductionIdentifying genomic regions under selection is the most challenging issue for improving important traits in animals. Few studies have focused on identifying genomic regions under selection in sheep.

EPIDEMIC PASTEURELLOSIS IN A BIGHORN SHEEP POPULATION COINCIDING WITH THE APPEARANCE OF A DOMESTIC SHEEP [PDF]

Journal of Wildlife Diseases, 2008
A pneumonia epidemic reduced bighorn sheep (Ovis canadensis) survival and recruitment during 1997-2000 in a population comprised of three interconnected wintering herds (Kenosha Mountains, Sugarloaf Mountain, Twin Eagles) that inhabited the Kenosha and Tarryall Mountain ranges in central Colorado, USA.

A case of thanatosis in domestic sheep

Behaviour
Abstract Thanatosis (feigning death, defensive tonic immobility) is a widespread anti-predator behavioural strategy in animals. Animals that have evolved this behaviour react to physical contact with the predator by displaying a persistent tonic immobility that makes them look like dead prey. This phenomenon has often been observed in

Sheep Movement Networks and the Transmission of Infectious Diseases [PDF]

, 2010
Background and Methodology: Various approaches have been used to investigate how properties of farm contact networks impact on the transmission of infectious diseases.

Changes in foraging behaviour suggest competition between wild and domestic ungulates: Guanaco and domestic sheep in southern Patagonia

, 2022
Previous attempts to address the presence of interspecific competition between domestic livestock and wild ungulates have focused largely on habitat or dietary overlaps.

Chromosome synapsis, recombination and epigenetic modification in rams heterozygous for metacentric chromosome 3 of the domestic sheep Ovis aries and acrocentric homologs of the argali Ovis ammon

Вавиловский журнал генетики и селекции, 2019
Hybridization of domestic animal breeds with their wild relatives is a promising method for increasing the genetic diversity of farm animals. Resource populations derived from the hybridization of various breeds of domestic sheep with mouflon and argali ...

Secreted Nonstructural Protein 3 is a Pathogenic Determinant of Orbivirus

Advanced Science, EarlyView.
This study uncovers a conserved PIP2‐dependent secretory pathway of orbivirus NS3 that induces vascular leakage. Pharmacological disruption of PIP2‐NS3 interaction significantly reduces viral pathogenicity and provides protective efficacy in murine models, establishing PIP2‐mediated NS3 secretion as both a key virulence determinant and a promising ...

Globally dispersed Y chromosomal haplotypes in wild and domestic sheep

, 2006
To date, investigations of genetic diversity and the origins of domestication in sheep have utilised autosomal microsatellites and variation in the mitochondrial genome.

Genomic evidence of improved fertility and adaptation in Iranian domestic sheep attributed to introgression from Asiatic Mouflon and urial

Scientific Reports
Due to the diverse climate in Iran, there has been an opportunity for the emergence of different domestic sheep breeds. On the other hand, two of the seven wild sheep species have settled in the broad areas of Iran.
