MUNOZ-ALONSO, Luis Antonio et al. Diversity of the herpetofauna in the Usumacinta basin, Mexico. Rev. Mex. Biodiv. [online]. 2018, vol.89, suppl., pp.79-99. ISSN 2007-8706. https://doi.org/10.22201/ib.20078706e.2018.4.2447.
A study is presented on the diversity and richness of the herpetofauna of the Usumacinta basin, based on 8,808 records from scientific collections, faunistic databases of the Comisión Nacional para el Conocimiento y Uso de la Biodiversidad, bibliographical references review, and field survey (2014-2015) for 3 study zones (Selva, Lagunas, and Costa) in the basin. For the study region, 42 species of amphibians and 110 species of reptiles were reported. The Selva zone was the richest in species, with 136, followed by Lagunas with 108 herpetozoos and Costa with a richness of 66 species. Values of effective number of species (qD) indicate differences between the study zones, showing Lagunas (1D = 20.98 ± 3.35) the highest value, followed by Costa (1D = 16.01 ± 2.35) and Selva (1D = 11.63 ± 1.64). The diversity and composition of three functional guilds (anurans, turtles and crocodiles) were analyzed. Selva and Lagunas are the most important zones based on their high richness and diversity of amphibians and reptiles.
