Primate Reproductive Strategies
The main focus of my present research is on understanding the design of primate visual signals and what role visual signalling has had in promoting and maintaining primate species.
I focus the guenons (tribe: cercopithecini) as a model group because they have extraordinarily diverse facial markings which evolved in a rapid evolutionary radiation. The guenons are a group of ca. 30 species which live in the forests of Africa. As they frequently form polyspecific associations, the putative function of their face markings is for maintenance of reproductive isolation. This begs the obvious question – are the complex facial patterns and the explosive speciation seen in this genus connected?
I’m taking a comparative approach to investigating signalling and signal design in this group. I’ve recently finished collecting image data on guenons which will allow me to understand the evolution of the shape and color of the multiple signal components of guenons’ face patterns in detail.
