1. Population divergence at small spatial scales : – theoretical and empirical investigations in perch
Sammanfattning : 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. LÄS MER
2. Sexual selection and the evolution of sex-role reversal in honeylocust beetles
Sammanfattning : 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. LÄS MER
3. Quantitative Trait Evolution in a Changing Environment in a Seed Beetle
Sammanfattning : During the last decades the climate has been changing more rapidly than in the preceding periods. This is for instance characterized by an increase in temperature. Interestingly, such changes in the environment are not necessarily constant over time as they often show high levels of fluctuation. LÄS MER
4. Living in a Variable Environment : Reproductive Decisions in Wild Bird Populations
Sammanfattning : In nature, environments are often variable and heterogeneous influencing ecological and evolutionary processes. This thesis focus on how animals interact with their environment and how that affects the reproductive decisions they make. LÄS MER
5. Male-female Coevolution in Bruchid seed beetles
Sammanfattning : Male-female coevolution is at the heart of biology. It is responsible for much of the diversity we see in behaviour and morphology, and it is thought to be an important engine of speciation. LÄS MER
