Abstract:Background: Although the scientific literature includes abundant and diverse studies conducted in tropical regions, little is known about the influence of edges in subtropical forest fragments Objective: This study aimed to evaluate the floristic-structural organization of tree communities along edge gradients in Araucaria Forest fragments in Southern Brazil. Results: We observed a high floristic and structural heterogeneity among fragments. This heterogeneity is a result of the species turnover that occurs in the region. It was possible to detect the influence of edge gradients on tree community organization in two fragments. Conclusion: We conclude that edge gradients can represent an important source of floristic-structural heterogeneity in Araucaria Forest fragments. However, the various response patterns observed for the tree communities indicate the complex nature of edge effects and suggest that the influence of edge gradients cannot be generalized for this forest formation.
