11. The Preservation of Favoured Morphs in the Struggle Between Sexes
Abstract : Sexual selection is particularly likely to promote population divergence, because sexual traits are expected to be subject to rapid evolutionary change. Identifying the relative roles of particular barriers to the amount of total reproductive isolation between populations or closely related species can provide important clues to the mechanisms of population divergence and speciation Phenotypic trait differences among populations are thought to reflect the interaction between the intensity of gene flow versus the strength of local selection and drift.

12. The evolution of courtship rituals
Abstract : The fact that many animals engage in highly ornamented and conspicuous display behaviours in connection with reproduction has received much attention in zoology ever since Darwin launched his theory of sexual selection. This thesis intends to investigate the evolution of such display behaviour. READ MORE

13. Guiding Concepts : Essays on Normative Concepts, Knowledge, and Deliberation
Abstract : This thesis addresses a range of questions about normativity, broadly understood. Recurring themes include (i) the idea of normative ‘action-guidance’, and the connection between normativity and motivational states, (ii) the possibility of normative knowledge and its role in deliberation, and (iii) the question of whether (and if so, how) normative concepts can themselves be evaluated.

14. Sexual conflict and selection on pistil and pollen traits
Abstract : 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. READ MORE

15. Game Theory and Agents
Abstract : A fundamental problem in multi agent systems is conflict resolution. A conflict occurs in general when the agents have to deal with inconsistent goals, such as a demand for shared resources. We investigate how a game theoretic approach may be a helpful and efficient tool in examining a class of conflicts in multi agent systems. READ MORE
