One hundred and five species of mammals are native to the Trans-Pecos region of Texas. The greatly varied terrain, climate, and vegetation make its mammalian life exceptionally varied, ranging from tiny shrews to great elks, from bats to aquatic beavers and muskrats, from desert-dwelling kangaroo rats to forest-loving chipmunks, and from an assortment of mice and rats to predatory cougars and coyotes.

This fully revised and updated edition of The Mammals of Trans-Pecos Texas provides a guide to the identification of these animals and summarizes important facts about their lives. With nearly every species illustrated with accurate, detailed pen-and-ink drawings by artist Chester O. Martin and color plates of some of the most iconic mammals that live in the Trans-Pecos region, it exemplifies how biologists integrate art with science to develop a wider appreciation for nature. The account of each species is arranged to contain a brief description of the animal, the geographic distribution of the species,  and a discussion of the natural history of the mammal. This authoritative work brings together an appreciation for and understanding of the diversity of fauna, life histories, and ecologies within a unique and fascinating landscape.
