Resumen

BOTELLO, Francisco; SANCHEZ-CORDERO, Víctor  y  ORTEGA-HUERTA, Miguel A.. Suitable habitat availability for mammals at regional (State of Guerrero) and national (Mexico) scales. Rev. Mex. Biodiv. [online]. 2015, vol.86, n.1, pp.226-237. ISSN 2007-8706.  http://dx.doi.org/10.7550/rmb.43353.

The State of Guerrero is ranked fourth in terms of biodiversity in Mexico, including 930 vertebrate species in its territory. However, Guerrero shows significant loss of its original natural habitats. It is evident the need to generate information on the processes involved in loss of natural habitats and to identify the impact on the distribution of species. We modeled the potential distribution of suitable habitat for 47 species of mammals using MaxEnt, and those were further refined to produce models of the current distribution of suitable habitats. The relationship between the amplitude of the potential distribution of suitable habitats and the proportion of remaining natural habitat for each species were examined, both at the state (Guerrero) and nationwide levels (Mexico), and there were identified areas of Guerrero needed to achieve fixed conservation goals. The results showed no significant correlation between the amplitude of species potential distribution of suitable habitats and species distributions of remaining areas of original habitat, neither at the state or national scales. In fact, there are significant differences in the proportions of remaining habitat between the 2 scales, suggesting that scale is an important factor in establishing conservation strategies for the same species at local, regional or national scales.
