About This Book

The study examines geographic variation in the plateau pocket gopher across Coahuila, México, using extensive museum and field specimens to map subspecies distributions and revise taxonomic boundaries. It compares pelage coloration and cranial measurements, documents habitat associations with soil type, elevation and vegetation, and identifies physical barriers such as mountains and major rivers that restrict gene flow. The authors note pronounced sexual dimorphism, explain methodological choices for comparisons, and provide specimen lists, measurement tables, and distribution maps to support their biogeographic and taxonomic conclusions.
