Interações entre aves frugívoras e plantas em um fragmento de mata atlântica de Minas Gerais
We studied the frugivorous birds and their fruiting plants during two years in a forest fragment in Viçosa, Minas Gerais State, Brazil. Our aim was to identify the importance of birds and plants based on an importance index ...
Bird-mediated selection on fruit display traits in Celtis ehrenbergiana (Cannabaceae)
(Evolutionary Ecology Ltd, 2014-08)
Background: In mutualistic interactions of fleshy-fruited plants and seed-dispersing birds, dispersers act as natural selection agents on fruit display traits. Bird-mediated phenotypic selection on maternal and seed level ...
Composição da avifauna, frugivoria e dispersão de sementes por aves em áreas de floresta estacional semidecidual e cerrado, no Parque Estadual de Porto ferreira, São Paulo
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Ecologia e Recursos Naturais, 2014-10-29)
In the São Paulo State predominated two large phytoecological formations: the semideciduous forests and the savanna. The extensive use of these areas mainly for cane sugar plantations and other monocultures, caused a high ...
Context-dependence in seed removal by lekking and non-lekking frugivorous birds in Brazilian Atlantic forest
Manakins are prominent fruit-eaters and seed dispersers in the Neotropics. Most manakin species establish lek areas where males devote long periods of time displaying to attract mates, interspersed with brief absences to ...
CLEANING ASSOCIATIONS BETWEEN BIRDS AND HERBIVOROUS MAMMALS IN BRAZIL: STRUCTURE AND COMPLEXITY
(Amer Ornithologists UnionLawrence, 2012)
O papel das aves na dispersão de sementes da espécie exótica Schefflera actinophylla (Apiales, Araliaceae): potencial de invasibilidade
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em Conservação da FaunaCâmpus São Carlos, 2019-02-05)
Anthropogenic activities affect landscapes, biodiversity and ecosystem services. These actions impair animal/plant interactions, mainly involving frugivorous birds. The dispersion played by birds allows plant species to ...
Temporal dynamics in the effectiveness of seed dispersal by birds visiting a tropical tree
Seed dispersal effectiveness (SDE) is related to the role of seed dispersal agents in realizing the reproductive potential of plants through seed dispersal and subsequent plant recruitment. The SDE of a given seed disperser ...
Is top-down control by predators driving insect abundance and herbivory rates in fragmented forests?
The effects of forest fragmentation on ecological interactions and particularly on food webs have scarcely been analysed. There is usually less herbivory in forest fragments than in continuous forests. Here we hypothesize ...
