Resumo: 	The variability of ecophysiological traits among populations can be a result of selection in response to environmental pressure and/or due to random factors, like the genetic drift. The analysis of both genetic and phenotypic variation within populations can lead to better understanding of adaptation in order to colonize different habitats. In the last years we have developed several studies with an widely ecogeographic distributed legume tree species, Plathymenia reticulata, which were focused on identifying specific morphological and physiological traits related to adaptation to the habitats of origin of each studied population. We studied populations from Atlantic Forest, Cerrado and ecotonal sites in relation to phenology, seed morphological traits and their relation with seed dispersion, seed dormancy and germination, and growth traits in a common garden experiment. In several analyzed traits we found high diversity in this species that can explain its occurrence in a broad geographical range. The existence of genetically based differences of traits in an adaptive way among savanna and forest populations suggests a degree of divergence that characterizes the existence of ecotypes from Cerrado and Atlantic Forest. We also pointed future perspectives in studies at population level in evolutionary ecophysiology and implications of these studies for flora conservation and habitat restoration.
