The present work carried out with native, adult and young trees of the species Ceiba pentrandra (sumauma), cultivated in flood plains (varzea) and in upland (terra firme) ecosystems. The objective was to obtain information about growth patterns of the species and to correlate them with different environmental conditions (varzea e terra firme), as well as to investigate anatomical and physical parameters of the wood. The wood quality of adult native trees was compared with the wood quality of young trees cultivated on varzea and terra firme. Investigations were carried out on the radial variations of density and anisotropy, as well as on the wood anatomical structure on the pith-bark direction on the samples of wood taken at breast height (DBH). From the results obtained, it can be concluded that the cultivated trees on the varzea and in terra firme ecosystems, as well as the native trees, presented an increase of density from pith to bark. The sctructural density of the cultivated trees at the terra firme ecosystem was higher, followed by the trees cultivated at the varzea, when compared with native sumauma. The anisotropy contraction index indicates that sumauma is highly dimensionally unstable. Therefore, its range of use in the area of construction is limited. |

Climate change may mean significant changes in crop productivity, including for planted forests, due to changes in climatic parameters. These impacts may be more intense in some regions of the country. Scientific investigation based on field data obtained over the long term and projected scenarios are important tools for planning and decision making that can help decrease vulnerability and risk for the forest sector in the near future. Along these lines, this study (which was conducted with support from Klabin S.A., a forest-based company) indicates changes that may be on the horizon, discusses climatic behavior in some regions of Brazil which are important centers for eucalyptus production, and projects impacts on productivity and carbon emissions/removal capacity in eucalyptus forests within the scenario of climate change. A highlight of this study is the use of the HadGEM2-ES model to predict rainfall, average temperature, evapotranspiration, water deficit, frost events, and minimum temperature at 10-year intervals until 2040. This is a differential, since other studies consider longer intervals. The study indicates climatic risk and the resulting impact on eucalyptus production in southern Brazil. However, detailed investigation in the municipalities of Itapetininga, Telêmaco Borba, and Otacílio Costa points to variations in the vulnerability of these environments. The study also examines the potential of these eucalyptus forests to accumulate carbon, indicating how and to what extent this function may be affected. Predicting potential changes is an intelligent way to prepare for and even ameliorate the impacts of climate change, thus making it possible to maintain the potential for the region and eucalyptus forests to make significant contributions to environmental quality and reaffirm the opportunities that are present for the forest sector within the context of the green economy and decarbonization of the economy.
