SYNDROMES OF SEED DISPERSAL ON GALLERY FORESTS AT DISTRITO FEDERAL-BRAZIL


Fernanda P. P. Lopes & José Felipe Ribeiro, EMBRAPA Cerrados


Seed dispersal was studied to point out its relative importance among species and individuals on 19 surveys. Among 511 species it was found 64,5% zoochory, 29,5% anemochory, 5% autochory and 1% barochory, with approximately the same ratio regarding number of individuals. Ornithochorous was the most representative within the zoochorous species. Zoochorous and anemochorous species were more frequent in the tree layer. The same syndrome shows an enormous fruit variety indicating several dispersor resource utilization and seed environmental use strategies. Even though floristically different, the evaluated Gallery Forests showed high dispersal syndromes similarity, indicating that for this phytophysionomy the dispersal spectra is very similar. It is suggested that seed dispersal patterns are a very important component of community structure organization on Gallery forests. (PRONABIO/MMA-GEF/WORLD BANK)
