The role of avian frugivores on germination and potential seed dispersal of the Brazilian Pepper Schinus terebinthifolius Biota Neotropica
D'Avila,Graziele; Gomes-Jr,Antonio; Canary,Ana Carolina; Bugoni,Leandro.
Frugivorous birds play a key role in seed dispersal and establishment of a range of plant species, including invasive weeds, such as the Brazilian Pepper Schinus terebinthifolius. The potential of seed dispersal of Schinus by birds with varied feeding behaviours was studied through seed-viability tests and germination experiments using seeds obtained from birds in the field and birds kept in captivity. It was found that seeds collected after gut passage in five bird species in the field had higher proportion of germination as well as higher germination rates compared to the control seeds. Viability of seeds ingested by the Blue-and-yellow Tanager Thraupis bonariensis, which mandibulates seeds before ingesting, was significantly lower than control seeds,...
