Patrón de distribución espacial de especies de Quercus y formaciones de encinos en Tamaulipas (México)

The Spatial Distribution Patterns in Quercus ecosystem formations are described for Tamaulipas State, Mexico, in basis of their bioclimatic and litologic factors. The Ecodinamics Regime Method was used for the analysis of the data, through the use of a Geographic Information System (GIS) with field verification of data. We analyzed four types of vegetal formations: mixed forest, oak forest, chaparral scrubland and montane humid forest. Distribution maps are presented for each vegetal formation in function of the bioclime and lithology. The resulting models generated fitve types of regimes for Tamaulipas oak formations: (Critropofilo, Euritermo-tropofilo, Euritermo-mesofilo Mesofilo-subhumedo and Tropofilo). The resulting data allows an ecological diagnosis for establish conservation proposals for the areas with the greatest diversity of Quercus in the region.
