Seed dispersal is a crucial ecosystem process that ensures the maintenance of tropical tree diversity (Terborgh et al., 2002).Frugivores disperse seeds away from the parent plants thereby potentially reducing mortality due to distance- and density-dependent factors like seed predation, herbivory and competition under the parent trees (Connell, 1971; Janzen, 1970).
