Abstract

The increasing importance in conserving and restoring natural environments, such as tropical forest, brings the need to develop programs of management and forest restoration projects that are increasingly eficiente and ecologically suited to the maintenance of biodiversity. In this context, the knowledge of the ecophysiology of native tropical species assume a fundamental role in assisting the adaptation of projects of maintenance of biodiversity, enabling the appropriate choice of species for each type of environment, as well as the ideal planting conditions. In addition to this, the study of the relationship of plants with the variations in their environments enables a better understanding of the intricate ecological relationships which shape tropical forests, such as their process of auto-regeneration and auto-maintenance via the dynamic of clearings. In this way, the research project aims to carry out a judicious study of the ecophysiology of tropical tree species enabling: a) the establishment of physiological parameters which permit a clear distinction between the successional groups; b) determination of the variation of the responses of different species to seasonal variations in a natural environment; c) determination of the degree of adaptation of each successional group to a particular environment in the forest (clearing or understory); d) verification of the differences in the mechanisms and degrees of tolerance to hydric deficiency between two different successional groups in semi-controlled conditions (greenhouse).
