"Geographic Variation in the Pocket Gopher, Cratogeomys castanops, in Coahuila, México" by Robert J. Russell is a scientific publication from 1955 that surveys the different types of plateau pocket gophers that populate the state of Coahuila, Mexico, and it examines how their habitats shape their traits. The book highlights how where these animals live affects their evolution, emphasizing the intricate details of their environment and examining how geographical elements impact their colonies. It carefully describes eleven different kinds of Cratogeomys castanops in Coahuila, which builds on prior studies and delivers new information gathered from detailed research in the field. The study explores how things like landforms and the dirt they live in can cut off and change particular kinds of these gophers, focusing on physical features like the size of their heads and the colors of their fur, while also noting how these animals act and live. This book deeply enhances our knowledge about the wide range of creatures in this area and helps explain how animals change and adjust to the demands of their surroundings.
