2. Bayesian Phylogenetic Inference
Abstract : In this thesis we consider two very different topics in Bayesian phylogenetic inference. The first paper, "Inferring speciation and extinction rates under different sampling schemes" by Sebastian Höhna, Tanja Stadler, Fredrik Ronquist and Tom Britton, focuses on estimating the rates of speciation and extinction of species when only a subsample of the present day species is available.

3. Evolution of host repertoires and the diversification of butterflies
Abstract : All herbivorous insects are specialized to some extent to their host plants, but the level of specialization varies greatly. Insect-plant coevolution is often invoked to explain the large diversity of herbivorous insects, but the role of specialization during diversification is still controversial. READ MORE

4. Systematics of Eucoilini : Exploring the diversity of a poorly known group of Cynipoid parasitic wasps
Abstract : Many animal species are still undiscovered, even in Sweden. This thesis deals with the wasps of the subfamily Eucoilinae (of Figitidae, Cynipoidea), a poorly known group of small parasitoids of Dipteran flies. READ MORE

5. Gall induction in gall wasps (Cynipidae s. lat.) : Insights from comparative genomics
Abstract : Cynipidae are a family of wasps (Hymenoptera), whose larval stages develop inside plant galls, that is, abnormal plant structures formed in response to the presence of foreign organisms. Most cynipids are gall inducers and are often capable of notable levels of host manipulation. READ MORE
