Resumo
In this study, we investigate the role of underling evolutionary process in current
phylogenetic structure of tree and shrub assemblages from rocky savanna, which is a
habitat type from Cerrado biome. Besides, we analyzed whether species that occurr in
both contrasting habitats types from Cerrado biome: rocky savanna and savannas, have
varying functional traits in intraspecific level in response to different environmental
conditions. For this, we splitted this dissertation in two chapters. In the first chapter, we
aimed to understand the role of historical and evolutionary contingencies,
diversification patterns and different clades distributions in shaping the current diversity
of trees and shrubs from rocky savannas. Furthermore, we also seeked understanding
the role of scale and species pool in phylogenetic structure of tree and shrub
assemblages from rocky savanna. In the second chapter, again using trees and shrubs as
study model, we investigated the occurrence of different ecological strategies in
individuals of the same species, according to the type of habitats in which they
occurred. Specifically, we addressed the variation of functional traits in species
occurring both in rocky savannas such as in geographically adjacent savannas.
