Comportamento alimentar de aves em Cecropia (Moraceae), em mata atlântica, no Estado de São Paulo

Abstract

This study is

The parakeet Brotogeris tirica feeds on and disperses the fruits of the palm Syagrus romanzoffiana in Southeastern Brazil

“…Transport of fruits removed from the mother-tree is only mentioned en passant for B. chiriri (Paranhos et al 2007) although for B. tirica there are records of transporting infructescence pieces of Cecropia spp., which bear minute seeds (Marcondes-Machado & Argel-de-Oliveira 1988). However, as both B. tirica and B. chiriri are regarded mostly as seed predators (Marcondes-Machado & Argel-de-Oliveira 1988, Paranhos et al 2007) the fate of the transported pieces remains to be evaluated.…”

“…However, as both B. tirica and B. chiriri are regarded mostly as seed predators (Marcondes-Machado & Argel-de-Oliveira 1988, Paranhos et al 2007) the fate of the transported pieces remains to be evaluated. In the present study, about 40% of the palm fruits were carried for a distance from the mother-tree by B. tirica individuals.…”

“…One focal-tree (cf. Marcondes-Machado & Argel-de-Oliveira 1988) of the palm Syagrus romanzoffiana was observed on 11 July 2007 and two other focal-trees were observed on 13 of the same month. The behaviour of the parakeets was initially assessed with naked eye at a distance of about 10-15 m, and then observed through binoculars and a 300 mm auto-phocus telephoto lens.…”

Diversidade de avifauna urbana em Joinville, Santa Catarina

“…Quanto às espécies frugívoras (13%), atribui-se a frequência verifi cada à diversidade de árvores frutíferas na área de estudo, que incluem espécies como Attalea dubia (palmeira-indaiá), Cecropia glaziovii (embaúba), Euterpe edulis (palmito-juçara), Hyeronima alchorneoides (licurana), Inga edulis (ingá-cipó), Inga marginata (ingá-feijão), Miconia cabucu (pixiricão), Miconia cinnamomifolia (jacatirãode-casca-lisa), Psidium guajava (goiabeira), Psidium cattleianum (araçá), Syagrus romanzoffi ana (jerivá), entre outras. Em estudos realizados com espécies do gênero Cecropia, puderam-se confi rmar 31 espécies de aves que visitam a espécie vegetal, e 17 alimentam-se da infl orescência, tais como Brotogeris tirica, Forpus xanthopterygius, Pionus maximiliani, Ramphocelus bresilius, entre outras (MARCONDES-MACHADO & OLIVEIRA, 1987), encontradas também no presente estudo. Em Cecropia glaziovii, especifi camente, foram verifi cadas, no trabalho de Mendonça (2004), cinco espécies de aves alimentando-se do fruto: Celeus fl avescens, Cyanocorax caeruleus, Ortalis squamata, Ramphastos dicolorus e Ramphastos vitellinus; quatro delas foram também encontradas no campus da Univille.…”

Frugivory and seed dispersal of Solanum granuloso-leprosum Dunal (Solanaceae) by birds in deciduous seasonal forest

“…The fruits have zoochoric dispersal syndrome ( Van der Pijl, 1972), and the vertebrates typically responsible for removing fruits are common to disturbed environments, including the frugivores that disperse Solanaceae seeds in these areas (e.g. birds, bats, rodents, opossums, and crab-eating foxes) (Marcondes- Machado and Argel-de-Oliveira, 1988;Müller and Reis, 1992;Reis et al, 1993;Rocha et al, 2008;Galetti and Morellato, 1994;Poulin et al, 1994;Sazima et al, 1994;Cáceres, 2002;Cáceres and Moura, 2003;Jacomassa and Pizo, 2010).…”
