From 2015 to 2019, researchers captured and analyzed blood samples from 364 mule deer across Texas’s Trans-Pecos and Panhandle regions to establish the first comprehensive hematologic and biochemical reference intervals for the species. This groundbreaking study, which included testing for diseases like bluetongue virus and epizootic hemorrhagic disease virus, provides wildlife managers with vital baseline health parameters to guide future mule deer conservation and restoration efforts.
