6. Systematics of Marionina (Annelida: Clitellata: Enchytraeidae)
Abstract : This thesis is about species of segmented worms that previously were placed in the genus Marionina Michaelsen, 1890, within the family Enchytraeidae, class Clitellata and phylum Annelida. These species are closely related to earthworms, but are much smaller and many of them are found between the sand grains in marine beaches. READ MORE

7. Species Limits, and Evolutionary History of Glassfrogs
Abstract : Recognizing the mechanisms of speciation and the limits of species is essential to understand the origin of biodiversity and how to conserve it. The general aims of my investigations during my doctoral studies were two-fold: to study evolutionary patterns and processes, and to provide specific and superspecific taxonomic classifications that try to reflect evolutionary history.

8. Phylogeny, taxonomy and species delimitation of water mites and velvet mites
Abstract : This study is part of the Swedish Taxonomy Initiative (STI) - one of the most ambitious all taxa biodiversity inventories in the world. One of the pillars in STI is to support taxonomic research on the most neglected taxonomic groups with the aim to lift the level of knowledge of biodiversity in the country. READ MORE

9. Taxonomy and Reticulate Phylogeny of Heliosperma and Related Genera (Sileneae, Caryophyllaceae)
Abstract : Heliosperma (nom. cons prop.) comprises 15—20 taxa, most of them endemic to the Balkan Peninsula. DNA sequences from the chloroplast (rps16 intron, psbE-petG spacer) and the nuclear genome (ITS and four putatively unlinked RNA polymerase genes) are used to elucidate phylogenetic relationships within Heliosperma, and its position within Sileneae.

10. Morphometric and molecular variation in the Nordic dogroses (Rosa Sect. Caninae, Rosaceae)
Abstract : In the present thesis, I investigate the hierarchical structure of morphometric and molecular diversity within and between the Nordic dogroses (Rosa Sect. Caninae, Rosaceae). I also investigate patterns of geographic differentiation and taxonomic relationships within the group. READ MORE
