Amphibians and reptiles of Yécora, Sonora and the Madrean Tropical Zone of the Sierra Madre Occidental in northwestern Mexico

Abstract

The Municipio de Yécora is located in the Madrean Tropical Zone of the Sierra Madre Occidental in eastern Sonora, Mexico. The herpetofauna of the region is very diverse with 93 species in 59 genera and 27 families known from the Río Yaqui to the Chihuahua border. This includes 20 species of amphibians and 73 species of reptiles. Thirty-six species in the Yécora area fauna have protection in NOM-059-SEMARNAT-2010 law. There are no non-native species in the fauna. The Yécora area herpetofauna is representative of the Madrean Tropical Zone and serves as a baseline to evaluate faunas of the Madrean Archipelago in northeastern Sonora and southeastern Arizona, USA as well as those to the south along the axis of the range.
