Our research projects range from the study of behavioral ecology and sexual selection to population genetics. The results of my former and ongoing research projects on rodents, hyraxes and – increasingly – fish contribute to a theoretical consideration of the interactions between the genetic structure of populations and the behavioral patterns that at once drive and result from genetic diversity.
These behaviors include prominently dispersal, mate choice, and social organization. In trying to understand the genetic structure of populations and dispersal patterns we primarily use molecular approaches, namely the study of mitochondrial and nuclear DNA variation (microsatellites) in wild living populations. In addition, we perform behavioral studies under controlled conditions in the laboratory to answer specific questions on the mating system, mate choice, kin recognition, and reproductive success. Zebrafish (Danio rerio), perch (Perca fluviatilis), and coral reef fish (Apogonidae) are used as model organisms.
The laboratory has more recently initiated behavioral studies on zebrafish to learn more about the link between genes, physiology and behavior. In order to understand and quantify behavioral deficiencies and changes caused by mutations it is instructive to know the variance in specific behavioral patterns of the wild type and compare this with specific mutants.
