1. Population divergence at small spatial scales : – theoretical and empirical investigations in perch
Abstract : Genetically structured populations arise when gene flow between groups of individuals is hindered by geographical, behavioural or temporal barriers. The identification of such groups is important for understanding evolution and has large implications for conservation concern. READ MORE

2. Sexual selection and the evolution of sex-role reversal in honeylocust beetles
Abstract : Sexual selection is the prime evolutionary force that makes males and females different. This process has long been viewed as one where male compete with one another and where females choose. READ MORE
