Primates are one of the most important frugivores in the tropics and are a major vector of seed dispersal. Vision has been traditionally seen as their main sensory modality, and their sense of smell has long been considered to be reduced to almost negligible levels. However, it is now known that many primate species possess high olfactory capacities which can provide information in many contexts – among them fruit selection.

Fleshy fruits are widely assumed to have evolved to be attractive to seed dispersers. Many works examined whether fruit traits such as size, shape or color have evolved as a response to selection pressures exerted by their main seed-dispersal vectors. However, little focus has been given to the potential roles of fruit odor in attracting frugivorous seed dispersers. So, the hypothesis that in some taxa fruit odor has evolved as a signal for dispersal vectors has been rarely addressed.

My work focuses on the interaction between these two loose ends: primate olfaction and the evolution of fruit odor. I investigate the chemical communication between primates and plants on both proximate and ultimate levels. On the proximate level, I try to understand which aspects of fruit odor are used by primates, and what information they draw from the VOC profiles of fruits. On the ultimate level, I use comparative methods to elucidate whether fruit odor can be considered an evolved signal whose function is to promote consumption and consequently seed dispersal by primates.
