Última Allometry of a neotropical palm, Euterpe edulis Mart. Acta Botanica Alves,Luciana F.; Martins,Fernando R.; Santos,Flavio A.M.. The stem allometry (stem diameter vs. tree height) of a Neotropical palm (Euterpe edulis) found in rain and seasonal forest of Southeastern Brazil was examined. Observed height-diameter relationships along the stem (diameter at ground level, (dgl), and diameter at breast height (dbh) were compared to three theoretical stability mechanical models: elastic similarity, stress similarity and geometric similarity. Slopes of log-transformed height-diameter relationships did not lie near those predicted by any stability mechanical models. Significant differences in stem allometry were found when comparing dgl to dbh, suggesting greater increase in dbh with height. The relationship between stability safety factor (SSF) and palm height showed that both dgl and dbh...

Silva; Santos,Flavio A.M.. The spatial distribution of fruits and juveniles of Enterolobium glaziovii Bentham were evaluated in four circular plots of 30 m radius, centered around reproductive individuals to determine whether the size of the parental crowns, topography, and canopy coverage influence these patterns. Each crown was subdivided into eight irregular triangles and the area of each was calculated. Each plot was subdivided into four sub-plots, two of them in an up-slope direction, and the other two in a down-slope direction. The canopy coverage for each plot was estimated at breast height (1.30 m) and at ground level, every three months during 1998. The numbers of fruits and juveniles of E. glaziovii were recorded. Although there were more fruit under the parental crown... Tipo: Info:eu-repo/semantics/article Palavras-chave: Conspecific influence; Crown size; Seed shadow; Topography.
