1. Integrative taxonomy of birds : Studies into the nature, origin and delimitation of species
Sammanfattning : Species are the basic currency in biodiversity studies but what constitutes a species has long been controversial. A major breakthough was the insight that most systematists agree that species are segments of population lineages, and that multiple lines of evidence should be employed and integrated, a procedure called integrative taxonomy.

2. Taxonomy, phylogeny, and secondary sexual character evolution of diving beetles, focusing on the genus Acilius
Sammanfattning : Sexual conflict can lead to antagonistic coevolution between the sexes, but empirical examples are few. In this thesis secondary sexual characters in diving beetles are interpreted in the light of sexual conflict theory. LÄS MER
3. Probabilistic Models for Species Tree Inference and Orthology Analysis
Sammanfattning : A phylogenetic tree is used to model gene evolution and species evolution using molecular sequence data. For artifactual and biological reasons, a gene tree may differ from a species tree, a phenomenon known as gene tree-species tree incongruence. Assuming the presence of one or more evolutionary events, e.g. LÄS MER
