16. Ultrastructural and systematic studies of cecidomyiidae (Diptera)
Sammanfattning : Examination of the abdomen of the adult female and the head capsule of the mature larva indicates the grat utility of the Scanning Electron Microscope (SEM) in examining structures when searching for useful characters to deal with the taxonomy and phylogeny of gall midges (Diptera: Cecidomyiidae). Some of the structures found represent adaptations of limited value for phylogenetic considerations at higher levels. LÄS MER

18. Monitoring gene level biodiversity - aspects and considerations in the context of conservation
Sammanfattning : The objectives of this thesis relate to questions needed to be addressed in the context of genetic monitoring for implementing the Convention on Biological Diversity for the gene level. Genetic monitoring is quantifying temporal changes in population genetic metrics. LÄS MER
19. Systematics of Eucoilini : Exploring the diversity of a poorly known group of Cynipoid parasitic wasps
Sammanfattning : 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. LÄS MER
20. Aspects of carnivoran evolution in Africa
Sammanfattning : This thesis concerns the evolution of African small carnivorans, with emphasis on East African Viverridae and Herpestidae (Carnivora, Mammalia). Viverridae and Herpestidae are two Old World feliform (belonging to the cat branch) carnivoran families with a confusing, and sometimes even misleading, taxonomic and systematic history, in addition to a scarce fossil record.
