Influence of environmental variables in the community of arboreal inselbergs

The inselbergs shelter a series of microclimates responsible for the differentiation of ecological conditions in the landscape, forming a complex system of gradients, which can often be characterized as an area of ecotone. The aim of this study was to characterize the vegetation structure and correlates it with the soil characteristics of different environments, in a fragment of semideciduous forest Montana, in the city of Coqueiral, MG. Have been launched 20 plots (40x10m and 20x20m) and sampled all individuals with CAP ≥ 15.7 cm. For the study of structure have been evaluated absolute dominance (DoA), absolute density (AD), cover (VC) and absolute frequency (AF). In a canonical correspondence analysis (CCA) correlating the values of abundance with soil variables. There was a relationship between the gradient distribution of species with soil characteristics, riparian vegetation showed the greatest difference in abundance species in relation to the soil characteristics.
