Biological Feasibility of Introducing Bighorn Sheep to the Jicarilla Apache Nation
The biological feasibility of introducing Rocky Mountain bighorn sheep (Ovis canadensis canadensis) to the Dulce area of the Jicarilla Apache Nation (JAN) depends on the availability and condition of potential habitat and the potential for disease risk, as pneumonia is the largest current threat to wild sheep populations. USGS researchers at the New Mexico Cooperative Fish and Wildlife Research...

Evaluating Adaptations of Desert Bighorn Sheep to Climate Change in the Southwestern U.S.
In the southwestern U.S., climate change is expected to increase the frequency of extreme droughts and cause an overall decrease in precipitation and increase in temperatures. These changes could impact a wide range of species in the region, even those adapted to living in arid environments. It’s possible that some species may be able to adapt to changing conditions by migrating to new...
The Impacts of Drought on Fish and Wildlife in the Southwestern U.S.
Species that inhabit the arid Southwest are adapted to living in hot, dry environments. Yet the increasing frequency and severity of drought in the region may create conditions that even these hardy species can’t survive. This project examined the impacts of drought in the southwestern U.S. on four of the region’s iconic species: desert bighorn sheep, American pronghorn, scaled quail...
The Effects of Drought on Southwestern Pronghorns
The antelope-like pronghorn is the fastest land animal in North America and has the longest land migration in the continental U.S—in fact, the species has been dubbed “the true marathoners of the American West”. While pronghorns are numerous in parts of their range, such as Wyoming and northern Colorado, they are endangered in others, such as the Sonoran Desert. In the arid Southwest...
The Effects of Drought on Desert Bighorn Sheep
Native to the southwestern U.S. and northwestern Mexico, the desert bighorn sheep is known for its ability to adapt to harsh, arid environments. However, this does not mean the species is immune to the effects of drought. In fact, the fragmented and isolated distribution of the desert mountain ranges that they inhabit means that they can’t follow distant rain storms without traversing...

Evaluating Adaptive Capacity of Desert Bighorn Sheep to Climate Change: Identifying Genetic Links to Climate Adaptations Evaluating Adaptive Capacity of Desert Bighorn Sheep to Climate Change: Identifying Genetic Links to Climate Adaptations
Natural selection may result in local adaptation to different environmental conditions across the range of a species. Understanding local adaptation, in turn, informs management decisions such as translocation to restore locally-extinct populations. We used a landscape genomics approach to detect genetic signatures of selection related to climatic variation among desert bighorn sheep...

Nutritional ecology forms the interface between environmental variability and large herbivore behaviour, life history characteristics, and population dynamics. Forage conditions in arid and semi-arid regions are driven by unpredictable spatial and temporal patterns in rainfall. Diet selection by herbivores should be directed towards overcoming the most pressing nutritional limitation (i...

Effects of Mycoplasma ovipneumoniae, abundance, and environmental conditions on bighorn sheep lamb:ewe ratios and adult survival in New Mexico Effects of Mycoplasma ovipneumoniae, abundance, and environmental conditions on bighorn sheep lamb:ewe ratios and adult survival in New Mexico
Mycoplasma ovipneumoniae is a primary causative agent responsible for initiating polymicrobial pneumonia in bighorn sheep (Ovis canadensis). Infections of bighorn sheep populations are typically characterized by initial all-age epizootics followed by long-term periods of repressed juvenile (lamb) survival. Populations of bighorn sheep in New Mexico, USA, were thought to be free of this...
