Herpetology of the American Madrean Archipelago and adjacent valleys

Abstract

Approximately 110 species of amphibians (18 frogs and toads, and 1 salamander) and reptiles (47 snakes, 39 lizards, and 5 turtles) are known from the American Madrean Archipelago and adjacent valleys. The high diversity of the herpetofauna comes from a variety of factors, including a convergence of biotic communities representing deserts, grasslands, and mountains. Other environmental and ecological factors weigh heavily into the equation, making this one of the nation’s richest herpetofaunas. Certain taxa are particularly speciose, including whiptails, rattlesnakes, and spiny lizards. Seventeen species are Mexican forms that barely enter the United States.
