We use an empirical approach to examine a large spectrum of subjects in behavioural and evolutionary ecology with emphasis on the evolution and maintenance of mating systems and the strategies and compromises between reproduction, immunity and evolution of sexual dimorphism and sperm competition. Other than our empirical approach to research, we have a deep interest in examining and synthesising primary literature by using meta-analysis, by commenting on statistical questions and by analysing scientific practices
