Abstract

POZO-MONTUY, Gilberto et al. Spatial and temporal analysis of the structure of the community of medium and large body sized mammals in the Biosphere Reserve El Ocote, southern Mexico. Rev. Mex. Biodiv. [online]. 2019, vol.90, e902731.  Epub Feb 12, 2019. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2019.90.2731.

Natural protected areas stand out as one of the most important strategies to reduce anthropogenic impact. However, the assessment of their effectiveness is difficult due to a lack of baseline long-term data. We assessed the temporal and spatial variation of the medium and large body-sized mammalian community (> 500 g) in the Biosphere Reserve Selva El Ocote (REBISO) and its area of influence. We compared the species richness recorded between 2013 and 2016 vs. the species reported up to 1996. Moreover, we compared the species richness and composition of the mammalian community among the core zone, buffer zone and the influence area of the reserve. During 2,835 camera-trap days we recorded 19 mammalian species (79.2% of which previously reported) in 13 families and 7 orders. The most commonly recorded species were: Cuniculus paca and Dasyprocta mexicana. Species such as Leopardus pardalis and L. wiedii had more records in the core zone than in the buffer and influence zone, whereas Didelphis virginiana and Nasua narica, were more recorded in the buffer and influence zones than in the core zone. Multiannual surveys are greatly needed to have a baseline to assess the impact of anthropogenic perturbation on the biodiversity.
