We analyzed the spatial distribution pattern of Pentaclethra macroloba to assist in the development of management plans and conservation of this species in estuarine floodplain forests. The study was conducted in an area of floodplain forest of 55.94 ha, in Mazagão, Amapá, Brazil. A census was performed and all individuals of ? 30 cm circumference at breast height (CBH), living and dead, were georeferenced. Ripley's K function was used to analyze the spatial distribution of the population, including mortality and diameter classes. The relationships between distance to the edge of inundation and density and basal area of the population were analyzed using linear regression. We recorded 993 live individuals and 22 dead. The distribution of the population was found to vary with the topographic gradient associated with the distance to the edge of the inundation. Diameter classes 1 (? 13.2 cm) and 2 (? 18.6 cm) were spatially aggregated close to the water and randomly distributed far from the water. Classes 3 (? 24.0 cm) and 4 (? 29.5 cm) were aggregated at all distances, and classes 5 (? 34.9 cm), 6 (? 40.3 cm), 7 (? 45.7 cm) and 8 (? 51.2 cm), were randomly distributed at all distances. Mortality was randomly distributed. The population density was 18 trees h-1 with a basal area of 49 m2 h-1, and both density (r2=0.51; p=0.0195) and basal area (r2=0.67; p=0.0039) increased with the distance from the edge of the inundation. We conclude that the spatial distribution and successful establishment of this species in floodplain forest are related to the dynamics of flooding and the resultant impacts on dispersal processes.

O objetivo principal dessa sistematização é avaliar uma experiência de intervenção para o desenvolvimento local, gerando aprendizado para subsidiar futuras ações de TT, por meio de erros e acertos. Para tanto, buscou-se identificar e compreender os fatores que influenciaram a paralisação de 90% das minifábricas de castanha-de-caju, a partir de uma análise em três níveis: o papel da organização social; as relações de poder; e a gestão administrativa, econômica e financeira. Ao mesmo tempo, analisou-se o método de transferência de tecnologia e construção do conhecimento. |
