摘要

TheAtlantic forest has historically been severely deforested, and only fragmentscurrently remain that are subject to a wide variety of anthropogenic impacts,including edge effects that can cause structural and functional degradation.The Tinguá Biological Reserve-RJ comprises approximately 26,000 hectares ofwell-preserved Atlantic Forest, but it is subject to impacts caused by twocanopy openings along oil pipelines. Comparisons were made between pipelineedges and forest interiors to evaluate edge effects on the structure anddynamics of those tree communities. Tree densities were higher along forestedges, apparently increasing over time. Tree basal areas, on the other hand,have decreased along edges due to higher mortality rates. Linear canopy openingedges showed higher densities of small trees, while the interior had more verylarge trees, indicating changes in successional processes and communitystructural patterns due to edge effects.
