Ecological Monographsv. Revista do Instituto Florestalv. The goals of this study were 1 to compare the frugivory and seed dispersal by frugivorous birds among Ficus species found in Semideciduous Seasonal Forest remnants and 2 to assess whether habitat loss influences frugivory and seed dispersal of these trees.

Tree species impoverishment and the future flora of the Atlantic Forest of northeast Brazil. Habitat loss and landscape fragmentation can affect species survival as well as community composition and their interactions. We randomly selected three to five individuals with ornitochorous fruits at the sampling time March-June, Morro do Diabo State Park The role of fruits traits in determining fruit removal in east Mediterranean ecosystems.

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.

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

Morales CL, L Galetto. 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.
