In the first bilingual work on the reptiles and amphibians of the US–Mexico border, top herpetologists come together to describe the herpetofauna of the states of this region, which includes more than 600 species of toads, frogs, salamanders, turtles, sea turtles, alligators, lizards, snakes, and sea snakes that are found along the almost 2,000-mile border between the two countries. Each chapter is devoted to one state—four in the US (California, Arizona, New Mexico, and Texas) and six in Mexico (Baja California, Sonora, Chihuahua, Coahuila, Nuevo León, and Tamaulipas)—with text in both English and Spanish. The chapters contain an introduction to the area, a review of the research, a sketch of the state’s physiography, and a description of the species present as well as the pertinent conservation issues they face. A color photo gallery includes images of nearly all species. Almost 40 percent of the featured native species are shared between the US and Mexico, reminding us that animals depend on the integrity of natural landscapes and proving the need for a comprehensive, bilingual reference to help lead a shared effort in the management and conservation of the borderlands.
