Frugivory of Persea lingue (Lauraceae) and its effect on seed germination in southern Chile

Frugivory is a common interaction mechanism between plants and animals in the temperate rainforest of southern South America. In this study, we examined primary dispersal and predation stages of Persea lingue (Ruiz et Pav.) Nees (Lauraceae), an endemic large-seeded tree of these forests. The main go...
