RESUMO:

In the Cerrado biome, a composition and structure of woody vegetation can be influenced by different factors that act in different spaces, especially between physiognomies with markedly different soils, such as the Typical Cerrado (CT) used on flat, deep and well-drained soils. , while the Cerrado Rupestre (CR) can establish in accidental relief, shallow soils and with rocky herring. In this study, we investigated how woody plants from two savanna environments, distinguishable by the type of substrate on the causes (CT and CR), which respond to regional (scalable and topographic) and local (edaphic properties) gradients, and determined the limits ecological changes and points of change at the community and population level. In addition, it is also available as changes in the composition and beta diversity of species, as well as changes in edaphic properties, considering two distinct environments (Cerrado Rupestre and Cerrado Típico). Our results revealed that the TC and CR environments have different ecological limits and points of change in the food and population level, considering the woody plants, both on a regional and local scale. We also show that there is a clear dissimilarity of the woody flora between CT and CR savannas, although the chemical and granulometric properties of the soil surface layers are not different between these environments. We also found that a beta diversity of the woody flora between the environments of both environments is exclusive for the replacement of species, with the most marginalized and central of the Biome being the ones that most contributed to a beta diversity. These results demonstrate that the editorial and topographic variability in the environments seems to have been more effective in explaining how changes in the responses of the communities that predict them are scalable. Our findings also revealed that, for the first time, the beta diversity standards for a woody flora in these environments are high due to the high substitution of species among communities. We believe that the high beta diversity is a reflection of the high floral variation of the woody plants, which exhibits unique flora among the sampled locations, due to their geographic and topographic characteristics, and not only due to the edaphic characteristics.
