RESUMOO presente estudo teve como objetivo caracterizar a composição florística e fitossociológica de uma floresta nativa no município de Caracaraí, Roraima, Brasil. Foram inventariadas todas as árvores com DAP > 10 cm em 9 parcelas permanentes de 100 x 100 m (1 ha cada Phytosociology of a dense ombrophilous forest in the northern Amazon, Roraima, Brazil ABSTRACTThis study was carried out to characterize species composition and phytosociology of a native forest located at Caracaraí, Roraima, Brazil. All trees with breast diameter (DBH) above 10 cm in nine 1-ha-permanent plots (100 x 100 m each) were inventoried. We observed 4,724 individuals (525 trees per hectare) distributed in 42 families, 111 genera and 165 species. The families with greater number of individuals were Fabaceae (1883), Lecythidaceae (609) and Sapotaceae (434), comprising 52% of the total. The higher densities of individuals were observed in the pioneer (219 trees ha -1 ), followed by secondary (193 trees ha ). However, species of secondary group had the highest species richness (95), followed by the climax (44) and the pioneer (26). The Shannon diversity index (H' = 3.27) and the value of Pielou equability (J = 0.64) were lower than those obtained in other floristic inventories in the Amazon, because of the high occurrence of Pentaclethra macroloba. The importance values (VI) were higher for Pentaclethra macroloba (52.1), Eschweilera bracteosa (23.7) and Pouteria caimito (8.1). The importance values of these three species alone accounted for 28% of the total VI across species. Most of the individuals (71.3% = 374 trees ha -1 ) were recorded in the middle stratum (12.4 m < height < 26.5 m) of forest. The forest community can be considered well-structured, mature and diverse, and so it is in good state of conservation.

The objective of this study was to evaluate the use of the MSI Sentinel-2 and SRTM data to estimate the volume of wood in a Semidecidual Seasonal Forest. Regression equations were fitted based on the remote sensing data, taking into consideration the individual bands and vegetation index of the MSI, elevation values and their derivatives obtained from the SRTM mission and the combination of the data drawn from the MSI and SRTM. RMSE and graphic analysis of residues were used to assess the accuracy of the fitted equations. The best model revealed values of 0.6508 and RMSE of 20.41% in the fit, and of 0.5680 and RMSE of 26.61% in the validation, using the combined MSI and SRTM data as predictors. The volume estimation using spectral data showed satisfactory results, highlighting the importance of topography in the prediction of the volume of wood for the area under investigation.

“…The spatial distribution of a species can be influenced by abiotic factors, such as water availability and light intensity, and biotic factors, such as predator or pathogen action and seed dispersal (Abreu et al, 2014). Specific spatial patterns found in forests are guided by spatial dependence of forest variables, such as density, basal area, height, volume, biomass and those conditioned by different levels of competition (Archanjo et al, 2012). Spatial distribution studies of tree species and their relationship with biotic and abiotic factors are fundamental for the advancement of basic research in ecology, control of biodiversity changes and to develop effective conservation actions for the species (Zhang et al, 2015).…”

The objective of this work was to characterize the spatial distribution pattern of the Euxylophora paraensis (yellowwood), to support conservation strategies of this species population in a managed 'terra firme' forest in the state of Pará. The study area is located in Fazenda Rio Capim, which belongs to The CKBV Florestal Ltda., in the municipality of Paragominas. For analyzing the spatial distribution of trees, geostatistics was used, based on the semivariogram modeling and kriging mapping. All evaluations had better adjustment to the spherical model, presenting the highest coefficient of determination in relation to the other models tested. Euxylophora paraensis presented an aggregate distribution pattern in the study forest, with spatial dependence described by the spherical model, forming tree clusters of size from 300 to 1000 m.
