Brazilian Journal of Biologyv. We found that the PFSP has a bird richness similar to large fragments of the region, although the most sensitive species and more demanding in the resources exploitation are less abundant compared to generalist species and to the most conserved frugioria of the surroundings.

Spatial patterns of seed dispersal, their determinants and consequences for recruitment. As traditional statistical methods were not suitable for our data, we used bootstrap data resampling to estimate confidence limits of fruit removal and seed dispersal and test for differences between fig trees and forest fragments.

FSP in the exotic bush was lower than in the native bush species. ABSTRACT The consumption of fleshy fruits by vertebrates is an fruugivoria phenomenon in the tropics, especially birds and mammals that have high proportions of frugivorous species. Despite the prevalence of generalist birds that disperse mainly small seeds of plants from the early succession stages, we found the PFSP has a diversified frugivorous bird-plant interaction network compared to other forest fragments of the State, due to the variety of available environments, connection with other surroundings fragments and its medium size and rounded shape, softening the matrix impact.

We conclude that natural perches and artificial perches with more elaborate architecture showed greater efficiency in attracting seed-disperser birds and increasing the seed deposition, being the most recommended for this area recovery and for ecological restoration projects.
