2. Evolutionary Resolutions of Conflicts with Mates and Offspring
Sammanfattning : In sexual conflicts and conflicts between parents and offspring, natural selection acts in different directions on the two sides. For example, males may be selected to achieve many mates, but female fitness may be maximised by monogamy. In this thesis I study the evolutionary outcome of these situations mainly by theoretical modelling. LÄS MER
3. Mating strategies and sexual conflicts in aquatic invertebrates: consequences for evolutionary differentiation
Sammanfattning : In this thesis I investigated how mating related strategies may differ among populations and how these strategies evolve in response to their local ecological environments. I have used two different study systems of aquatic invertebrates: diving beetles (Dytiscidae) and the fresh water isopod Asellus aquaticus. LÄS MER
4. Sexual conflict and selection on pistil and pollen traits
Sammanfattning : The incidence of sexual selection in plants is today acknowledged, however, just as in animals, evolution and maintenance of mate choice is gravely underexplored. Moreover, the potential for sexual conflicts to occur in plants has only been assessed empirically to a very limited degree. LÄS MER
5. Sexual conflict and male-female coevolution in the fruit fly
Sammanfattning : Harmony and cooperation was for long believed to dominate sexual interactions. This view slowly started to change 25 years ago and is today replaced with a view where males and females act based on what is best from a costs-benefits perspective. LÄS MER
