Geographic Variation in the Pocket Gopher, Thomomys bottae, in Colorado

"Geographic Variation in the Pocket Gopher, Thomomys bottae, in Colorado" by Phillip M. Youngman is a scientific investigation into how pocket gophers adapt to different environments within Colorado. The study identifies six unique types of pocket gophers, or subspecies, each shaped by its specific habitat, based on the examination of 249 gopher specimens. Youngman's work describes key physical differences among these subspecies, like color and skull structure, connecting these traits to the diverse regions of Colorado, which include the Colorado Plateau and Southern Rocky Mountains. The book highlights how geography influences the gophers' adaptations and habitat choices.
