FERNANDEZ-BADILLO, Leonardo  and  GOYENECHEA-MAYER GOYENECHEA, Irene. Amphibians and reptiles from the Valle del Mezquital, Hidalgo, Mexico. Rev. Mex. Biodiv. [online]. 2010, vol.81, n.3, pp.705-712. ISSN 2007-8706.

Valle del Mezquital Hidalgo, Mexico is known for its high biological richness, but little is known about its herpetofauna. A study to list the amphibians and reptiles of 3 different zones at the Valle del Mezquital was carried out. We analyzed their distribution in different types of vegetation, their microhabitat and relative abundance in 12 monthly trips during 1 year for a total of 108 days. We sampled transects over 9 types of vegetation. Thirty species have been reported for this area (7 amphibians, 30 reptiles), 8 reported for the first time from Valle del Mezquital. Most of the species were present within crops (26), 14 within the temperate zone and 13 within the irrigation zone. The herpetofauna at Valle del Mezquital uses 27 different microhabitat, being "under rock" the most used by 22 species. Most of the species, both amphibians and reptiles were considered rare.
