Floristic structuring of woody plants from the Chaco in light of abiotic factors

Abstract The phytogeographic domains are structured by different geoclimatic (abiotic) factors, such as altitude, temperature and precipitation. Thus, our goal was to investigate the possible abiotic factors that related floristic richness of tree-shrub component throughout Chaco remnants. This study is based on data presence absence species in remnants data. In addition, World Wildlife Fund shapes were used differentiate dry wet Chaco. database aggregated 36 areas 522 species. clusters obtained affinity between groups mainly temperature, altitude seasonality where precipitation more evident, there greater dissimilarity composition vegetation. On other hand, gradient explained homogeneity humid attributed three factors. Dry presents compared Humid Still, play a dominant role structuring trees shrubs most homogeneous formations integrate
