The central theme of this thesis is about the edge effect from the fragmentation of ecosystems and our central objective is to contribute to the knowledge about this effect in forest fragments in the Cerrado and Atlantic Forest biomes. In this sense, we propose here two different approaches for each of these biomes: In the Cerrado Biome the great "Knowledge Gap" on the production of Litter in fragments of this biome was emphasized and we propose possible measures to fill these gaps.In the Atlantic Forest an approach was taken on the edge effect in forest fragments, where we verified how this effect occurs from the edge to the center of the fragments using the NDVI vegetation Index. In addition, it was verified the most suitable model to analyze the dynamics of the edge effect. When evaluating the quality of the linear model and the nonlinear model we found that the nonlinear model was the most adequate for the description of the edge effect in the Atlantic Forest biome. Based on the study of all these aspects about the edge effect, we hope to subsidize works on fragmentation in these two Biomes and also contribute to the execution of projects that aim at the conservation of forest fragments in a wide scale
