AbstractBirds are known to be important dispersers of plants, since the passage of seeds through the digestive tract often has a positive influence on germination percentage and speed. In this study, proportions of germination in different substrates were compared between Myrsine (Myrsinaceae) seeds collected manually and those ingested by birds. The guilds of birds that fed on M. umbellata and M. lancifolia were identified and comprise 24 and 12 species, respectively. A higher germination proportion was found among seeds defecated by birds and sowed in the study area. The study also found differences between the guilds of frugivores in both synchronopatric species. Therefore, we suggest that M. umbellata and M. lancifolia are important food sources by birds that play a positive influence for enhance germination of Myrsine.
