AGUILAR-LOPEZ, Melany et al. Lista taxonómica y estructura del ensamblaje de los mamíferos terrestres del municipio de Tlanchinol, Hidalgo, México. Mastozool. neotrop. [online]. 2013, vol.20, n.2, pp.229-242. ISSN 1666-0536.

The Tlanchinol municipality is an important region of conservation since it harbors a great diversity of vegetation and one of the most extensive cloud forest areas in the state of Hidalgo. This state ranks the third place in terms of national coverage of this vegetation type. However, there are few studies that focus on the mammals that inhabit these forests. The aim of this paper is to present an updated taxonomic list of the land mammals of the municipality, and an analysis of the assemblage structure in relation to trophic organization, body size, geographical distribution and the conservation status of the species. The previous was done in order to update all knowledge about terrestrial mammal assemblage in the region. Fieldwork was conducted between November 2006 and July 2008, and it was complemented by a review of published information. We used direct methods (trapping and observations) and indirect methods (tracks, droppings, animals provided by the residents and interviews) to obtain the information. We recorded 42 species: 4 are didelphimorpha species, 1 cingulata, 2 soricomorpha species, 9 carnivores, 2 artiodactyla and 24 rodents. Seven species are considered under some risk category (16.6%) and eight (19%) are endemic to Mexico. Most species are herbivores (40.5%) and omnivores (33.3%) and are small in size (<100 g). In this work we recorded 16 new species for Tlanchinol municipality thus contributing significantly with broad and updated information about richness and assemblage structure of mammals within the municipality.
