Forests loss and habitat fragmentation due to agricultural activity could be related to different ecological processes such as biotic dispersion, as well as the maintenance of native plant diversity avws exotic plant invasions. Fragmentation reduced fruit removal and seed dispersal of F. Keystone plant resources inthe tropical forests.


A total of 32 bird species were observed consuming figs of six Ficus species. Patterns of fruit-frugivore interactions in two Atlantic forest bird communities of southeastern Brazil: We randomly selected three to five individuals with ornitochorous fruits at the sampling time March-June, Dispersal of avves seeds by fruit-eating birds of tropical forest understory.

By monitoring and evaluating fruiting and frugivory events in focal and ad libitum sessions, 31 ornithochoric species were found that provide fruits to 38 species of frugivorous birds. Sorry, but Javascript is not enabled in your browser! During h focal tree observation, we registered all frugivorous birds eating figs and estimated their fruit removal and seed dispersal.
