1. Evolutionary genetics and consequences of inbreeding in sand lizards (Lacerta agilis)
Sammanfattning : Inbreeding is a well-known phenomenon in evolutionary and conservation biology. In the 19th century, Charles Darwin demonstrated the detrimental effects of inbreeding in plants, followed by over a century of extensive research including various animal and plant taxa. LÄS MER
2. Deflating selection : On the interpretation and application of evolutionary theory
Sammanfattning : Although the theory of evolution is well-established it nevertheless presents us with a few unresolved matters of interpretation. One key task is to get clear about what exactly one should take the term 'natural selection' to denote. LÄS MER
3. Evolutionary consequences of sex-specific selection
Sammanfattning : Sex-specific selection is widespread, evident by the evolution of sexual dimorphism in many traits in sexually reproducing taxa. The reason why the sexes may experience selection that differs in direction or magnitude is often linked to the reproductive strategies associated with the sex-specific reproductive physiology.

4. Metapopulations dynamics and sex-specific resource allocation in Silene dioica
Sammanfattning : Rising archipelagos provide unique settings for the study of the temporal and spatial dynamics of their biota. This offers the possibility to study the ecology and genetics of early successional processes; both between islands that differ in age and within islands when already established organisms have to keep pace with the changing environment. LÄS MER
5. Models of Cooperation, Learning and Catastrophic Risk
Sammanfattning : Our world presents us with dangers and opportunities. Some of these dangers and opportunities are easier to handle if two or more individuals learn to cooperate. This thesis contributes five papers about cooperation, learning and catastrophic risk. LÄS MER
