Title: Monkey seed dispersal and predation. Photos by S. A. Mori.

Description: Cacajao calvus (the bald uakari) eats parts of flowers and fruits and often is a dispersal agent. In contrast, Pithecia pithecia (the golden-headed saki) also eats fruits but is also a predator of plants, e.g., it eats and destroys the seeds of immature fruits of Lecythidaceae. An example of diplochory is the bald uakari eating a fruit with small seeds, the pulp is digested, and the seeds are dipersed. In turn, some of these seeds can be gathered by ants that may carry them away to consume fragments of pulp at their nest.
