Competition arises when two co-occuring species share a limiting resource. Potential for competition is higher when species have coexisted for a short time, as it is the case for herbivores and livestock introduced in natural systems. Sheep, introduced in the late 19(th) century in Patagonia, bear a great resemblance in size and diet to the guanaco, the main native herbivore in Patagonia. In su...

Booroola gene is one of the major genes in the enhancement of ovulation rate and could be an attractive candidate gene for ovulation rate in sheep. Molecular technologies have been widely used for discovery of mutations in animal species. These mutations have major effects on the important economic traits of sheep and goats. This study was conducted to identify the mutation in FecXG region of e...

Tick-borne hemoparasites (TBHs) are a group of pathogens of concern in animal management because they are associated with a diversity of hosts, including both wild and domestic species. However, little is known about how frequently TBHs are shared across the wildlife-livestock interface in natural settings. Here, we compared the TBHs of wild Grant's gazelle (Nanger granti) and domestic sheep (O...

This study employs the maximum entropy modelling technique to investigate the geographic distribution pattern of wild sheep (Ovis Orientalis) on Tangeh Sayyad Proteced Area. A set of eight environmental predictors is employed together with presence-only records of wild sheep. Two methods has been used to improve the performance of modeling: density-based occurrence thinning and performance-base...

The most common sources of environmental noise are human transportation systems which can have catastrophic effects on physiology and behavior of wildlife species. Spatial models of noise propagation from roads in ecological sensitive region could be very useful tools for prediction of roads impacts. The goal of our study was to apply a straightforward, accurate, and affordable approach for mod...
