Bioclimatic systematization of Sierra Madre Occidental (Mexico) and it's relationship with vegetation belts. Polibotánica [online]. 2017, n.43, pp.125-163.

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 geobotánical 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 intotal) of which corresponding geobotánical 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.

Keywords : indicators; distribution; isobiclimates; vegetation belts; Sierra Madre Occidental.
