Abstract

BLANCAS-CALVA, Epifanio; NAVARRO-SIGUENZA, Adolfo G.  and  MORRONE, Juan J.. Biogeographic patterns of the avifauna of the Sierra Madre del Sur. Rev. Mex. Biodiv. [online]. 2010, vol.81, n.2, pp.561-568. ISSN 2007-8706.

We analyzed the avifauna of 26 sub-basins of the Sierra Madre del Sur biotic province and their biogeographical relationships applying a parsimony analysis of endemicity (PAE). Based on the distributional information of the species obtained from the Atlas de las aves de México and published literature, we built a data matrix for 26 sub-basins and 437 species. The single cladogram obtained suggests the existence of three groups of sub-basins:the first with 5 sub-basins from arid environments, geographically located in north-southeastern Oaxaca; the second with another 5 sub-basins form subhumid environments; and the third one with the remaining sub-basins, from humid and environmentally more complex habitats.

Keywords : birds; parsimony analysis of endemicity; Mexican Transition Zone.
