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. Frugivory by birds in degraded areas of Brazil.

Determinants of seed disperser effectiveness: In the smallest forest remnant, large-bodied birds, considered high quality seed dispersers, cannot be found anymore and small and generalist birds are not able to compensate for this loss on seed dispersal service. Effects of habitat fragmentation on biodiversity. Por otro lado, algunos estudios muestran que los movimientos de aves son mayores dentro de bosques continuos que entre fragmentos Van Houtan et al. 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.

Fragmentation reduced fruit removal and seed dispersal of F. Finalmente, en sitios de bosque continuo se compararon dos pares de especies arbustivas Lantana grisebachii Stuckert ex Seckt.

There was availability of attractive fruit throughout the year, with peak productivity between September and October, in line with the pre-reproductive period of birds and the arrival of migratory species.

Frugivorous interactions with large sized birds, such as the Cracidae and Ramphastidae families, considered as potential seed dispersers, were not recorded. 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.
Reproduction for commercial use is forbidden. Forests loss and habitat fragmentation due to agricultural activity could be related to different ecological processes such as biotic dispersion, as well as the maintenance of native plant diversity and exotic plant invasions.
