“…The pioneer Cecrop ia species have a wide distribution in South America (Berg, 1978) and their seeds are animal-dispersed: C. obtusa and C. sciadophylla are dispersed by birds, marsupials, bats and primates (Charles-Dominique, 1986); C. obtusifolia by marsupials, primates and carnivores (Estrada et al, 1984;Medellin, 1994); C. peltata by marsupials, bats, primates and rodents (Fleming & Williams, 1990); and C. concolor by birds (Silva, 1980). Otherwise, Cecropia fruits are frequent items in the diet of frugivorous vertebrates (Estrada et al, 1984;Fleming & Williams, 1990), and can be considered keystone species (Medellin, 1994).…”
