Diversidad de mamíferos de la Reserva Natural Sierra Nanchititla, México

Abstract

The Sierra Nanchititla Natural Reserve (SNNR) is the second largest natural protected area in the State of Mexico, however its biodiversity is largely unknown. The aim of this research was to estimate its mammalian diversity. Direct trapping was used to capture small mammals and camera-trapping for the study of medium and large mammals. Diversity was calculated from Margalef's index, dominance and equity were evaluated through Simpson's and Shannon-Wiener indexes, respectively. Fifty three species were registered, 3 of them are the first record for the State of Mexico, 10 are endemic to Mexico and 4 are considered in some category of vulnerability by the Mexican government. The area is inhabited by 5 of the 6 Mexican felid species. The mastofaunistic composition of SNRN was compared with that of the Sierra Purépecha, Michoacán, according to Jaccard's index, the similarity between them is low, sharing 38% of species. Considering the results, it is clear the importance of SNNR, regarding its mastofaunistic diversity, and the need to implement strategies for its conservation.
