1. The evolution of sexual dimorphism and its genetic underpinnings
Sammanfattning : Sexual dimorphism often constitutes the largest phenotypic variance within species but it is puzzling how sexual dimorphisms evolve because most of the genome is shared between the sexes. Sexually antagonistic (SA) selection on a shared genome sets the stage for intralocus sexual conflict. LÄS MER
2. Phylogenetic analyses of sexual size dimorphism
Sammanfattning : .... 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. On the endemic Fucus radicans in the Baltic Sea
Sammanfattning : The brown macroalgae Fucus radicans is endemic to the Baltic Sea, but little is known about this newly described species. This thesis investigates the ecology and role of F. radicans within the species poor Baltic Sea ecosystem. The thallus of F. LÄS MER
5. Evolutionary ecology of newts
Sammanfattning : Sexual dimorphism, predator avoidance and migratory behaviour are adaptive traits that show variation at the population and species level. Such features respond to the environment in the broad sense, that is, when both abiotic and biotic components are included. LÄS MER
