Abstract [en]

Primates are now known to possess well-developed olfactory sensitivity and discrimination capacitiesthat can play a substantial role in many aspects of their interaction with conspecifics and theenvironment. Several studies have demonstrated that olfactory cues may be useful in fruit selection.Here, using a conditioning paradigm, we show that captive spider monkeys (Ateles geoffroyi) displayhigh olfactory discrimination performance between synthetic odor mixtures mimicking ripe andunripe fruits of two wild, primate-consumed, Neotropical plant species. Further, we show that spidermonkeys are able to discriminate the odor of ripe fruits from odors that simulate unripe fruits thatbecome increasingly similar to that of ripe ones. These results suggest that the ability of spidermonkeys to identify ripe fruits may not depend on the presence of any individual compound thatmark fruit ripeness. Further, the results demonstrate that spider monkeys are able to identify ripefruits even when the odor signal is accompanied by a substantial degree of noise.
