Atlantic Forest bioregionalization and its relation with environmental factors

Geographic bioregionalization is the practice of delimiting regions based on the distribution of biota in space, generating units that carry biological significance. The increasing modernization of classification techniques and the abundance of data from currently available vegetation inventories are an incentive to the practice of bioregionalization with the use of such data. The objective of this study was to elaborate the bioregionalization of the Atlantic Forest based on data of presence and abundance of plant species, and to identify the environmental and historical factors that structure the distribution of the generated groups. In order to classify the biome into groups, we used sorting and grouping techniques, and to investigate the influence of environmental and historical factors on the groups, we used multinomial logistic regression models. From the presence and abundance data, 21 and 14 groups were generated, respectively.
