Frugivory by toucans (Ramphastidae) at two altitudes in the Atlantic Forest of Brazil
(2001-01-01)
Toucans are prominent components of the tropical American avifauna. Although these birds are very conspicuous, there are few ecological studies focusing on them. In this study, the diets of four sympatric toucans (Ramphastos ...
Frugivory and habitat use by fruit-eating birds in a fragmented landscape of southeast Brazil
(Neotropical Ornithological Society, Usgs Patuxent Wildlife Research Center, 2004-01-01)
To investigate the movement of seeds transported by fruit-eating birds in an agricultural, fragmented landscape of the Atlantic forest of southeast Brazil, I asked which bird species are the main seed dispersers in such ...
Seed dispersal of Attalea phalerata (Palmae) by Crested caracaras (Caracara plancus) in the Pantanal and a review of frugivory by raptors
(2004-12-01)
We observed Crested caracaras (Caracara plancus) consuming and dispersing fruits of the palm Attalea phalerata at Pantanal, Brazil. We reviewed the literature of seed dispersal by raptors and suggest that raptors may affect ...
Tempo de passagem de sementes pelo trato digestório de aves frugívoras, uma primeira avaliação no Brasil
(2012-03-01)
The transit time of seeds ingested by frugivorous animals has important implications for the spatial distribution of seeds and their dispersal distance. Nevertheless, this parameter is rarely included in seed dispersal ...
Differential seed germination of a keystone palm (Euterpe edulis) dispersed by avian frugivores
(2012-11-01)
The effectiveness of seed dispersal by vertebrates has been analysed by examining both quantitative and qualitative components (Jordano & Schupp 2000, Schupp et al. 2010). While the quantitative component is relatively ...
Specialized Seed Dispersal in Epiphytic Cacti and Convergence with Mistletoes
(2013-07-01)
Mistletoes represent the best example of specialization in seed dispersal, with a reduced assemblage of dispersal agents. Specific dispersal requirements mediated by the specificity of seed deposition site have apparently ...
Impacto humano afeta negativamente a dispersão de sementes de frutos ornitocóricos: Uma perspectiva global
(2007-06-01)
Ornithochorous fruits make up an important part of the diet of birds and many studies have related the different morphological types of fruits with the choice by birds. We analyzed the intrinsic characteristics of plants ...
On the reliability of visual communication in vertebrate-dispersed fruits
(Wiley-Blackwell, 2012-01-01)
1. Several fundamental aspects of communication between plants and their mutualists are poorly understood. It remains unclear whether plant signals are accurate and reliable, that is, whether they recruit mutualists by ...
Frugivory by phyllostomid bats (Mammalia: Chiroptera) in a restored area in Southeast Brazil
(2011-01-01)
We studied the potential contribution of frugivorous bats to the reestablishment of vegetational diversity in a restored area. We analysed the diets of the bat species and the differences between them in the consumption ...
