Pronghorn research (IMAGE) University of Wyoming Caption Melanie LaCava, a University of Wyoming Ph.D. candidate in the Program in Ecology, from San Diego, Calif., collects a genetic sample of a pronghorn at a Wyoming Game and Fish Department hunter check station in Medicine Bow. LaCava and Holly Ernest, a UW professor of wildlife genomics and disease ecology, and the Wyoming Excellence Chair in Disease Ecology, led a study of Wyoming pronghorn. The study, published in the May 29 online issue of the Journal of Mammalogy, showed pronghorn living in Wyoming exhibit little-to-no population genetic differentiation even though their range spans hundreds of kilometers, multiple mountain ranges and three major interstate highways.
