| Sumario: | This study shows the results of a herpetofaunal inventory carried out in the municipality of Balancán, Tabasco, Mexico, during the rainy and northern season of 2019 and dry season of 2020. For data collection, systematic day and night surveys were conducted using the inspection technique by time-limited visual encounter (VES) in three types of vegetation: grassland = PAST, jungle = SELV and forest = BOSQ. We accumulated a sampling effort of 288 search person-hours, observing a total of 564 individuals of 43 species, 13 amphibians and 30 reptiles, belonging to four orders, 22 families and 37 genera. The vegetation type that presented the greatest richness was the SELV with 30 species, followed by the BOSQ with 29 and finally the PAST with 28 species. The species accumulation curves generated for both groups indicated a high representativeness during the study period. Based on the Jaccard index, the vegetation types BOSQ and PAST showed a similarity value of 50% (J = 0.5), while SELV and BOSQ presented the least similarity with 47% (J = 0.47). Of the total registered species, 12 are listed within some risk category for Mexico. Internationally, 37 species are listed on the IUCN Red List of Threatened Species and three species are listed on Appendices I and II of CITES. According to the EVS, 17 species presented a moderate or high environmental vulnerability score. This work constitutes the first systematic inventory of amphibians and reptiles for the municipality of Balancán, providing information on their diversity and serving as a baseline for future research and conservation projects focused on this faunal group. |
