Sistematización bioclimática de la Sierra Madre Occidental (México) y su relación con los pisos de vegetación

Abstract

Based on bioclimatic diagnosis of 377 meteorological stations throughout the physiographic province of Sierra Madre Occidental (SMO) and the floristic and vegetation information collected, have been identified bioclimatic territorial units, of which his geobotanical characterization is performed. The area is included in the Tropical Macrobioclima, where Tropical Desert, Tropical Xeric and Tropical Pluviseasonal bioclimates are presented. To each one, their bioclimatic belts have been identified (19 in total) of which corresponding geobotanical diagnosis is made through the identification of their respective vegetation belts, emphasizing the structure of the potential natural vegetation, its main floristic markers and its catenal distribution. These results are completed with maps of bioclimates, thermotypes and ombrotypes, and three vegetation transects made at different latitudes.
