Elaenia as a fruit consumer and seed disperser. Frugivorous animals disperse their seeds and contribute for the maintenance of fig trees populations.

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 fragments of the surroundings.

III, we evaluated the potential of bird perches in increasing the seed rain in an abandoned pasture within the PFSP limits.
Therefore, we installed seed traps under natural perches living trees and artificial, noting the number of deposited seeds increased proportionally to the amount of landing perches structures.

SUMMARY Forests loss and habitat fragmentation due to agricultural activity could be related to different ecological processes such as biotic dispersion, as aes as the maintenance of native plant diversity and exotic plant invasions.

Revista Chilena de Historia Natural 73 3: Revista Brasileira de Ornitologia, v. The mixed reforested area, although it has some exotic plant species, is ecologically more functional for birds and, due to its proximity to the fragment, apparently contributes to the maintenance of the resident and visiting bird communities of this region by providing food resources.

Ficus eximia did not show a clear pattern, once it was only highly consumed by birds in a specific microhabitat not included on the fragmentation analysis.

Seed dispersal and frugivory: These Ficus species, however, may depend more upon bats and capuchin monkeys than on birds for seed dispersal, and may even benefit from the increase in extension of forest edges. Mean fruits survival time days between fragments and continuous forest for woody plant species or species with other life forms. Para Batalha et al. By monitoring and evaluating fruiting and frugivory events in focal and ad libitum sessions, 31 ornithochoric species were found that provide fruits to 38 species frugivorix frugivorous birds.
