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.

Seed dispersal and frugivory: The American Naturalistv. Ecological Monographsv. Acta Botanica Brasilica, v. 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.


Frugivory by birds in degraded areas of Brazil.

The extensive use of these areas mainly for cane sugar plantations and other monocultures, caused a high loss of habitats.

Plant reproductive susceptibility to habitat fragmentation: Frugivorous interactions with large sized birds, such as the Cracidae sves Ramphastidae families, considered as potential seed dispersers, were not recorded. Listas das aves do Brasil.

Annual Review of Ecology, Evolution and Systematics Zanthoxylum coco Gillies ex Hook. Determinants of seed disperser effectiveness: We recorded 90 interactions involving 22 species of plants and 33 species of birds. Results suggest that the dispersion of the ornitochorous fruits would be related to the process of fragmentation, but small fragments are used by birds as feeding sites, which confers them a high conservation value.

The FSP for the plant community showed statistically significant differences between small fragments and continuous frugivoris. The feeding ecology of tanagers and honeycreepers in Trinidad.

SUMMARY Forests loss and habitat fragmentation due to agricultural activity could be related to different ecological processes such as biotic dispersion, as well frugivroia the maintenance of native plant diversity and exotic plant invasions. ABSTRACT The consumption of fleshy fruits by vertebrates is an important phenomenon in the tropics, especially birds and mammals that have high proportions of frugivorous species.

Frugivorous animals disperse their seeds and contribute for the maintenance of fig trees populations. We randomly selected three to five individuals with ornitochorous fruits at the sampling time March-June, Tackling the habitat fragmentation panchreston. How to cite this article.

This behavior of bird species would 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.
