Multimodal sexual communication in primates

Reproduction is a crucial activity for animals which directly modulate individual’s fitness and therefore the survival of a group, a population, and to a larger scale to a species. However, reproduction imposes costs on individual, due to the investment of energetic resources into mating and reproduction (gamete production, maternal care) and to the physical costs of mating (sexual harassment, intra-sexual competition). It has been suggested sexual communication have evolved to accomplish reproduction efficiently. Sexual communication includes selection on females to signal their reproductive state or condition, and on males to discriminate that state, so as not to waste energy on non-reproductive mating. While female primates can display multiple information through multiple sensory channels (behavioral, auditory, visual, and olfactory communications) most studies still focus on investigating the signal content of one or few traits. Therefore, my work aims at conducting comparative studies to investigate the forms (traits and modalities involved) and functions (signaling and perceiving intra-cycle, inter-cycle, and inter-individual variations) of the sexual communication of various primate species to better understand how social and environmental constraints have modulated the evolution of primate sexual communication and mating strategies. This collaborative research involved researchers from Japan (KUPRI), France (CNRS - MNHN), UK (Durham and Wolverhampton Universities), and USA (New-York University).

Current Projects

My current project further explores the evolution of female colorful traits among primates. Across human cultures, red is steadily associated to love and fertility. Although probably reinforced by social learning, there is evidence that the link between red and fertility is not a product of societal conditioning alone and may have roots in human biological heritage. Thus, my project aims to determine whether women share with female primates a colorful trait involved in sexual communication. Especially, my research focuses on the role of lips coloration, from signal content to signal perception. My main questions are: Does fine-scale variation in lips coloration inform about the timing of ovulation / reflect individual differences in fertility? and, Is intra-cycle / inter-individual variation in lips coloration perceptible to men and women? This project was funded by a Grant-in-Aid for Research Activity start-up from the Japan Society for the Promotion of Science (JSPS).
