“…The two sites have steeply sloping relief, outcroppings of limestone rocks (belonging to the Bambuí group), predominant Lithic Neossols, and seasonal climate according to the Köppen classification (Figure 1, Table 1). These two communities were previously studied by Silva et al (2020) and showed high β diversity, sharing only 23.4% of their species. Both areas are protected and are in a good state of conservation.…”

“…Therefore, we believe that these conditions allowed certain functionally different species to colonize the area through stochastic dispersion processes (Tuiller et al 2007, Mason et al 2011, Gotzenberger et al 2012, Cadotte et al 2017. This is because the Presidente Juscelino forest is located in an ecotonal area, with floristic influence from the Cerrado and the Atlantic Forest (Silva et al 2020). This scenario may have contributed to increase the functional diversification of this area, incorporating typical attributes of humid regions in the community composition (Gentry, 1983, Poorter et al 2019.…”

“…Moreover, DSFs include floristically very distinct communities (Gonzaga et al 2013). This dissimilarity is attributed to the input from the adjacent biomes, which provides them with high α and β diversity (Silva et al 2020). Although there is this floristic diversity, when studying dry forests, some authors have found that functional diversity responds to the environmental gradient, resulting in trait convergence as the environment becomes more restrictive (Méndez-Toribio et al 2017, Raymundo et al 2018, Menezes et al 2020).…”

Deciduous seasonal forests (DSFs) have a peculiar floristic composition, with species capable of surviving periods of high water deficit in a year. Our goal was to demonstrate that abiotic filters lead to the assembly of two DSF communities that have high floristic dissimilarity. For this, we characterized the environment of the areas and used the community-weighted mean (CWM), functional richness (FRic) and functional dispersion (FDis) indices for regional recognition of functional patterns. The local assessment of assembly rules was carried out using null models. We found differences in the FRic and FDis between the areas, which was attributed to the different floristic influences exercised on the communities. However, in both, the typical attributes of dry formations were dominant (CWM), indicating that, on the regional scale of study, the dry season acts as a filter in the composition of species in the communities. On a local scale, stochastic dispersion was identified as the most influential mechanism in the assembly of communities. We conclude that deterministic and stochastic processes act in the assembly of the studied communities, and the proportion of each of these depends on the scale, with abiotic filtration predominating on a regional scale and stochastic dispersion events on a local scale.
