A Study of Fruit–Frugivore Interactions in Two Species of Durian (Durio, Bombacaceae) in Sabah, Malaysia

We determined the fruit predators and seed dispersers of two species of durian (Durio, Bombacaceae), D. graveolens and D. zibethinus, which have contrasting aril color and timing of dehiscence by observing fruiting trees in Deramakot forest reserve. In our observations in the wild, both species were extensively predated by orangutans before fruits matured. Durio graveolens was dispersed by black hornbills and D. zibethinus was dispersed by long‐tailed macaques.
