This data product contains estimates of habitat quality and connectivity for mountain lion, mule deer, desert bighorn sheep, and black bear, and combined estimates of high habitat and connectivity areas for all species. The analysis area was a 236,000 square kilometers that encompassed the Navajo Nation, which includes portions of Arizona, New Mexico, and Utah. The estimates of habitat quality were created with spatially explicit habitat variables and either an expert-based linear combination process (for mountain lion and mule deer) or a generalized linear mixed model-based estimation that used radio-collar telemetry data (for desert bighorn sheep, black bear, and pronghorn; collected between 2005-2011). Habitat...

Climate often drives ungulate population dynamics, and as climates change, some areas may become unsuitable for species persistence. Unraveling the relationships between climate and population dynamics, and projecting them across time, advances ecological understanding that informs and steers sustainable conservation for species. Using pronghorn (Antilocapra americana) as an ecological model, we used a Bayesian approach to analyze long-term population, precipitation, and temperature data from 18 populations in the southwestern United States. We determined which long-term (12 and 24 months) or short-term (gestation trimester and lactation period) climatic conditions best predicted annual rate of population growth...

This data set represents statewide migration corridors or routes for pronghorn antelope (Antilocapra americana) within the state of Wyoming. The original data was compiled by the Wyoming Game & Fish Department and produced on mylar map overlays which corresponded to U.S. Bureau of Land Management 1:100,000 scale quadrangle maps. Wyoming Open Spaces Initiative at the University of Wyoming digitized this hardcopy data to develop the original GIS layers in 2002. These have since been updated and continue to be maintained by the Wyoming Game and Fish Department.

Few dietary studies of pronghorn (Antilocapra americana) have been conducted in semidesert grasslands and little mention has been made of Mexican-tea or ephedra (Ephedra spp.) as a browse species. During summer 2003, we estimated the mortality rate of a pronghorn population in southwestern New Mexico to be nearly 75%. As the severity of the summer drought progressed, pronghorn used ephedra (Ephedra torreyana) until many plants showed signs of heavy browsing. Perennial browse is limited in this area, and we suspect this normally winter forage species was used as an emergency food. If pronghorn carrying capacity in semidesert areas is limited by insufficient forage during dry years, browse occurrence and condition...
