For example, there is the tucumã-dopará (Astrocaryum vulgare Mart.), a semidomesticated species that attracts the food, pharmaceutical and cosmetic segments. Important in the structure and functioning of several ecosystems and has high cultural value for traditional peoples. Given its importance, the objective of this work was to know the structure and spatial distribution of this species, and to understand the effect of environmental gradients on the occurrence in the municipality of Salvaterra, on the island of Marajó, Pará. The study was conducted in 11 communities of residents, distributed in five different physiognomies, in which 42 sample units were established in which biometric information was mapped and collected from all individuals and categorized by height classes, subsequently submitted to statistical analysis. The results found showed that the tucumã-do-pará showed typical density of the species with abundance of juveniles and aggregate spatial distribution pattern for all studied physiognomies. In addition, environmental variables such as slope, geomorphology, pedology and distance from individuals to rivers were shown to be linked to variations in growth and development of the morphological characteristics of this species. Finally, the high occurrence value of this species in the physiognomies found may be linked to the land use system, contributing to the formation of environments favorable to its development.PPGCA - Estudos de ecossistemas amazônicos
