Geographic Variation in the Pocket Gopher Cratogeomys castanops in Coahuila Mexico

The study begins with a thorough introduction to the pocket gopher, emphasizing its ecological role and the significance of understanding geographic variation in species. The authors present their methodology, detailing the collection of specimens from various localities across Coahuila, and the methods employed for analyzing morphological traits and genetic markers.Key findings reveal notable variations in size, fur coloration, and skull morphology among populations, which correlate with environmental factors such as soil type and vegetation. The authors discuss these variations in the context of evolutionary adaptations, suggesting that geographic isolation may play a significant role in the observed differences.
