12. 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

13. The spatial structure of genetic and morphometric variation in Corylus avellana (Betulaceae): pattern and scale
Abstract : In the present thesis, I investigated the spatial structure of genetic and morphometric variation in the widespread wind-pollinated shrub Corylus avellana (L.) Betulaceae, hazel, and related the variation to geographic distribution and different spatial scales. READ MORE

14. Genetic variation, polyploidy and hybridization in Scandinavian Anthericum ramosum and A. liliago (Anthericaceae)
Abstract : In this thesis, I investigate the differences in breeding system, levels of genetic variation and hierarchical structure of genetic diversity between Anthericum ramosum and A. liliago. The two species differ in ploidy level and flowering time, but have similar habitat preferences, reproductive biology and geographic distributions in Scandinavia. READ MORE

15. Variation in Silene vulgaris and S. uniflora (Caryophyllaceae): genetic diversity, gene flow and habitat selection
Abstract : Genetic and morphometric variation was studies in the three closely-related taxa Silene vulgaris (a widespread weed), S. uniflora ssp. uniflora (restricted to coastal habitats) and S. uniflora ssp. READ MORE
