RESUMO:

Species co-occurring in different typologies with different climatic and edaphic characteristics may present ecological strategies to optimize the acquisition and use of resources, as well as variations in their morphofunctional attributes - phenotypic plasticity - as a response to the environment. Soils poor in resources and with diverse environmental conditions, such as those of the Amazon under study, play a strong filtering and selection effect on the species, especially Curatella americana L., popularly known as a trash or caimbe, which has a high value of ecological importance and in addition to presenting its unknown structural and functional characterization. This species occurs widely in the Cerrado biome and, in Pará, in disjoint spots of Amazonian savannas, and had its first record of occurrence in restingas on the Amazonian coast. In this context, we propose the present project whose objective will be to evaluate the ecological strategies of C. americana integrating knowledge about its morphophysiological and anatomical attributes through the functional attributes analyzed in the typologies that occur in the Amazon, with the hypothesis that environmental conditions influence different plastic patterns responses in the specie. The study will be carried out in restingas and savanoid vegetation of Soure and Salvaterra - Marajó PA, savanoid vegetation of Alter do Chão and grasslands of Cametá and Vigia. To answer the questions proposed we will evaluate a set of leaf attributes (leaf area, leaf mass by area, leaf thickness, succulence, density, anatomy, secondary metabolites and nutrients), wood attributes (density and anatomy) and soil attributes in 15 individuals by typology. These measured attributes will be used to determine the ecological strategies of C. americana in the different Amazonian typologies and to predict their response to changes in the availability of resources.
