Resumen

ESCALANTE, Tania; RODRIGUEZ, Gerardo  y  MORRONE, Juan J.. The provinces of Mexican Mountain Component based on continental mammals distribution. Rev. Mex. Biodiv. [online]. 2005, vol.76, n.2, pp. 199-205. ISSN 2007-8706.

Different approaches have been used to analyze the limits between the Nearctic and Neotropical regions, such as biogeographic indices, panbiogeographic analyses and cladistic biogeographic analyses. We examine the proposal of a Mexican Mountain Component that was suggested by a previous study of insects, analyzing the provinces of this zone applying the parsimony analysis of endemicity (PAE) to distributional maps of terrestrial mammals, in relation to the Nearctic and Neotropical regions. We found that the Sierra Madre Occidental province has a greater Nearctic influence, whereas the Chiapas province belongs to the Neotropical region.

Palabras llave : Mexican Transition Zone; biogeography; province; region.
