HECHEM, Viviana; PADRO, Alfredo  and  MORRONE, Juan J. Patrones distribucionales de la flora vascular de la estepa Patagónica y su relevancia para la regionalización biogeográfica. Darwiniana, nueva serie [online]. 2015, vol.3, n.1, pp.5-20. ISSN 0011-6793.

We analyzed distributional data of vascular plants of the Patagonian province, in order to contribute to its biogeographic regionalization. We constructed maps with the localities of 112 specific and subspecific taxa endemic to the Patagonian steppe, obtained their individual tracks, and undertook a parsimony analysis of endemicity (PAE), in order to identify generalized tracks and test a recent biogeographic classification. The Payunia, Subandean and Central subprovinces were not supported by the plant taxa analyzed, as their respective districts were not recovered as generalized tracks. It would be important to analyze other plant and animal taxa in order to explain the inconsistencies found.
