摘要：
The edge effect is defined as the change of biotic and abiotic characteristics in the first meters of a forest fragment from the edge towards its interior. In fragments formed by human activities, this change generates increased richness and abundance, as well as changes in the structure of the forest species of soil seed bank in the border region. This study demonstrates that in natural fragments of cloud forests, the abundance and richness positively influence the linear relation from the edge to interior, mainly by distances of 120 and 180 meters from the edge. This effect can be a result of new plant growth, or 'pioneer' occupation in gaps in the forests generated by large fallen trees.
