dc.description.abstractDesigning protected areas capable of supporting organism flow is critical for species persistence acrosswide scales. Here, we evaluated the capacity and protection level of forest fragments to sustain connec-tivity for carnivores in the Atlantic Forest. We simulated potential dispersal considering species spatialdemands and quantified the importance of patches with different sizes in sustaining species movement.We found that patches smaller than species home-range size represented more than 95% of the patchesused during species dispersal. These small remnants play a key role in upholding connectivity for carni-vores, especially for species capable of moving long distances. Although the forest structure did supportmost species movements, our results showed that some species must cross matrices composed by cropsand pasture to complete their trajectories. Moreover, between 29% and 70% of the area around the species’movement paths, which could act as potential corridors, overlap with human activities. Current estab-lished protected areas – mainly targeted for sustainable use – cover only 15% of the entire extension ofsmall remnants enrolled in species dispersal. We reinforce that conservation efforts should not overlookthe potential of small forest fragments to improve connectivity. Integrating key fragments with forestrestoration and matrix management would benefit long-term species persistence.pt_BR
