Frugivory by birds in cerrado in the city of Uberlândia, Minas Gerais

From seed production to seedling establishment: Dispersal of Amazonian birds in continuous and fragmented forest. As traditional statistical methods were not suitable for our data, we used bootstrap data resampling to estimate confidence limits of fruit removal and seed dispersal and test for differences between fig trees and forest fragments.

Metadata Mostrar registro completo. 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.

Fragmentation reduced fruit removal and seed dispersal of F. Acta Botanica Brasilicav. Determinants of seed disperser effectiveness: A total of 32 bird species were observed consuming figs of six Ficus species. Even if this Ficus community as a whole does not seem to interact with birds, it remains relevant, frugivorka, to test whether F.

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

Frugivorous interactions with large sized birds, such as the Cracidae and Ramphastidae families, considered frguivoria potential seed dispersers, were not recorded. 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. Aves de Argentina y Uruguay: Some features of this site may not work without it.

In the mixed reforested area, This document is only for private use for research and teaching activities. We recorded 90 interactions involving 22 species of plants and 33 species of birds. The role of animal seed dispersal in accelerating native forest regeneration on degraded tropical lands. Patterns of fruit-frugivore interactions in two Atlantic forest bird communities of southeastern Brazil: Revista Brasileira de Botanicav.

Forestry Ecology and Management, v. Important steps in an invasive process. 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.

Revista Brasileira de Ornitologia, v. Fruit eating by birds in a forest fragment in southeastern Brazil. Elaenia as a fruit consumer and seed disperser. How long fruit-eating birds stay in the plants where they feed: ABSTRACT The consumption of fleshy fruits by vertebrates is an drugivoria phenomenon in the tropics, especially birds and mammals that have high proportions of frugivorous species. Tackling the habitat fragmentation panchreston. Ficus eximia did not show a clear pattern, once it was only frugivori consumed by birds in a specific microhabitat not included on the fragmentation analysis.

Asymmetrical pattern was found in the interactions in which few species are responsible for most interactions. Zanthoxylum coco Gillies ex Hook. The effect upon other Ficus species remains to be tested.

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. Mean fruits survival time days between fragments and continuous forest for woody plant species or species with other life forms. 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 frugivoriz of available environments, connection with other surroundings fragments and its medium size and rounded shape, softening the matrix impact.

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.
