| description | This study was developed in order to determine the annual and seasonal herpetofauna diversity of Montecillo Santa Cruz, Municipality of San Francisco del Mar, Oaxaca, at the south of the Isthmus of Tehuantepec. Between November 2010 and November 2011, over 48 field work days (24-dry season and 24-wet season), two 500 m long and 10 m wide transects were established in open grassland, nanchal, tropical deciduous forest and riparian vegetation. We recorded in an area of 20 km2, a total of 49 species (10 species of amphibians and 39 species of reptiles). This richness represents 30.61% of the total herpetofauna of Oaxaca. A total of 46 species were recorded at the wet season (10 amphibians and 37 reptiles) and 37 at the dry season (4 amphibians and 33 reptiles). The 30.61% of the total are listed in some risk category in the NOM-059-SEMARNAT-2010, one species is listed as critically endangered (Ctenosaura oaxacana) by the IUCN Red List, and four more are in the Appendix II of CITES. Throughout the study, the tropical deciduous forest presented the highest alpha diversity (H’ = 3.2900, 1 / D = 20.6), while the open grassland was the one with less diversity (H’ = 3.1664, 1 / D = 17.14). On a seasonal basis, the deciduous forest showed the highest diversity (H’ = 3.2900, 1 / D = 20.6 wet season, H’ = 3.0850, 1 / D = 17.71 dry season), while the lowest diversity was recorded in the riparian vegetation during the wet season (H’ = 3.1009, 1 / D = 16.61), and in the grassland (H´= 2.7095, 1 / D = 11.40) during the dry season. Throughout the study, the vegetation associations that shared a greater number of species were tropical deciduous forest and riparian vegetation (P = 0.7045 and S = 0.5613), coinciding with the seasonal results (J = 0.6500 and S = 0.4921 wet season, J = 0.6333 and S = 0.4489 dry season). We found a high diversity in a relatively small area, so the area can be considered as important for the distribution of amphibians and reptiles, and therefore is essential to establish conservation and management measures for these species and their habitats. |

Se determinó la composición anual y estacional de la diversidad de anfibios y reptiles de Montecillo Santa Cruz, municipio de San Francisco del Mar, Oaxaca, en el Istmo de Tehuantepec. Entre noviembre de 2010 y noviembre de 2011, a lo largo de 48 días de muestreo (24 en la temporada seca y 24 durante la temporada húmeda), se establecieron transectos diurnos y nocturnos de 500 metros de longitud y ancho aproximado de 10 metros en pastizal abierto, nanchal, selva baja caducifolia y vegetación riparia. En un área de 20 km2 se registró un total de 49 especies (10 especies de anfibios y 39 especies de reptiles), lo que representa el 11.52% de la herpetofauna total para Oaxaca. De éstas, 46 especies se registraron en la temporada húmeda (10 anfibios y 36 reptiles) y 37 en la temporada seca (4 anfibios y 33 reptiles). El 30.61% del total se encuentra en alguna categoría de riesgo en la NOM-059-SEMARNAT-2010, una especie está catalogada como críticamente en peligro (Ctenosaura oaxacana) en la lista roja de la UICN, y cuatro más están en el apéndice II de la CITES. A lo largo del estudio, la selva baja caducifolia fue la asociación vegetal que presentó la mayor diversidad alfa (H´ = 3.2900, 1/D = 20.6), mientras que el pastizal presentó la menor diversidad (H´ = 3.1664, 1/D = 17.14). Para las dos temporadas monitoreadas, la selva baja caducifolia presentó la mayor diversidad (H´ = 3.2900, 1/D = 20.6; H´ = 3.0850, 1/D = 17.71, respectivamente), mientras que la menor diversidad se presentó en la vegetación riparia durante la temporada húmeda (H´ = 3.1009, 1/D = 16.61), y en el pastizal (H´ = 2.7095, 1/D = 11.40) durante la temporada seca. A lo largo de todo el estudio, las asociaciones vegetales que compartieron mayor número de especies fueron la selva baja caducifolia y la vegetación riparia (J = 0.7045 y S = 0.5613), coincidiendo con los resultados estacionales (J = 0.6500 y S = 0.4921 temporada húmeda; J = 0.6333 y S = 0.4489 temporada seca). Se registró una alta diversidad en un área relativamente pequeña, por lo que puede considerarse a la zona como de importancia para la distribución de anfibios y reptiles, de ahí que sea indispensable el establecimiento de medidas de manejo y conservación para estas especies y sus hábitats.
