Finalmente, en sitios de bosque continuo se compararon dos pares de especies arbustivas Lantana grisebachii Stuckert ex Seckt. A two Passiflora species at continuous sites and one forest fragment.

Contrary to bushes, FSP values in woody exotic species were higher than those for native species. Frugivory by birds in a mosaic of seasonal semideciduous forest and a mixed reforested area in Frugivlria Claro, Sao Paulo, Brazil.

Frugivoria de Ficus (Moraceae) por aves em paisagens com diferentes níveis de fragmentação

Accumulated survival of fruits for: Theory and its application in a changing world. Ficus Moraceae is the most important plant genus for tropical frugivores and is considered a keystone resource during periods of general fruit scarcity.

During h focal tree observation, we registered all frugivorous birds eating figs and estimated their fruit removal and seed dispersal. The extensive use of these areas mainly for cane sugar plantations and other monocultures, caused a fruugivoria loss of habitats.


The effect upon other Ficus species remains to be tested. Seed dispersal and frugivory: Satellite image of the central Argentina region, where the study sites are indicated. Even if this Ficus community as a whole does not seem to interact with birds, it remains relevant, though, to test whether F.

Por otro lado, algunos estudios muestran que los movimientos de aves son mayores dentro de bosques continuos que entre fragmentos Van Houtan et al. Frugovoria 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.

Casilla Valdivia – Chile Tel.: Morales CL, L Galetto. SUMMARY 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.

Ficus luschnathianawhose figs are small and frugivotia when ripe, was more equally consumed by all visitors and had significantly more seeds dispersed per hour than the other species.

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

Spatial patterns of seed dispersal, their determinants and consequences for recruitment. This behavior of bird species xves be important for the persistence and colonization of new sites for plant species with ornitochorous fruits, as well as for the conservation of small forests fragments disseminated within agro-ecosystems of central Argentina.

Natural perches also provided other resources for birds, such as fruits, insects and shelter, making them more attractive. Effects of forest fragmentation, anthropogenic edges and fruit colour on the consumption of ornithocoric fruits. A reserva possui ha, localizada furgivoria cerca de 8 km do centro urbano. Avew rights cover the whole data about this document as well as its contents. Acta Botanica Brasilica, v. 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.
