Research interests


Environmental and social constraints play a major role in the evolution of cooperative breeding systems. Here, sexually mature individuals forgo own reproduction at the benefit of others, which represents one of the most derived and complex social behaviours occurring in the animal kingdom. In fish, cooperative breeding is known from several cichlid species endemic to Lake Tanganyika. These species occupy distinct habitats and face variable environmental conditions also on a within population level. This makes cooperatively breeding cichlids a highly suitable study system to investigate the evolution of cooperative breeding. Therefore, in my PhD studies I aim at understanding the evolution of cooperative breeding in cichlids, with a special focus on factors mediating population structure and dispersal decisions. I will focus on a within and between species comparison using different social cichlids.
