Frugivory and seed dispersal by birds in an altitudinal Atlantic Forest, Teresopolis-Brazil A. C. Rudge, A. Piratelli, F. M. Pina-Rodrigues; Universidade Federal Rural do Rio de Janeiro, Seropedica, Brazil. Effective seed dispersal is critical to restoration of degraded areas and to successful recruitment in fragmented forests. We investigated seed dispersal by birds in and among four fragments of different sizes and degrees of isolation by agricultural activities Fragments isolated (F3= 3.2 ha; F4= 62 ha) and connected (F2 = 8 ha; F1= 23 ha) were studied by mist-netting in two sites per fragment. Bird captures were performed; seeds were collected from feces and germination was carried out in controlled chambers at 30oC. Frugivores birds were more abundant (38.3%; n= 31), followed by omnivores and insectivores. Seeds of Miconia and Lendra sp. were the most frequent and were dispersed by Chiroxiphia caudata and Thraupis sayaca that promoted increasing of seed germination while Hemitriccus diops and Turdus leucomelas were not effective in breaking seed dormancy.
