Evolutionäre Verhaltensökologie von Cichliden

I am mainly interested in functions and mechanisms of kin discrimination. In particular, my research focuses on kin recognition mechanisms and the operation of kin selection in different contexts ranging from juvenile shoaling over intra-sexual competition to mate-choice and parental care. As model system I use Pelvicachromis taeniatus, a socially monogamous cichlid fish with intense biparental brood care from West Africa. The unusual kin mating preferences in this species provide the possibility to examine the ecological and genetic requirements for adaptive inbreeding. In this context, also levels of inbreeding in natural populations using microsatellites are estimated.

Pelvicachromis taeniatus
 

A further research focus lies on the function of (especially female) conspicuous body colouration in sexual selection and the evolution of sperm traits in Pelvicachromis taeniatus.

Moreover, I am interested in predator-induced behavioural and morphological plasticity (based on chemical cues) as well as in host/parasitic interactions in gammarids and their acanthocephalan parasites.
