1. Gene description, activity quantification and physiological responses of mitochondrial alternative NAD(P)H dehydrogenases
Sammanfattning : In addition to proton-pumping complex I, the plant respiratory chain contains type II NAD(P)H dehydrogenases. These extra enzymes do not pump protons and consequently do not contribute to the electrochemical proton gradient. LÄS MER
2. Geographic Variation, Hybridization and Evolution in the Bladder Campions, Silene vulgaris and S. uniflora (Caryophyllaceae)
Sammanfattning : In the present thesis, I investigated the inter- and intraspecific variation in the Silene vulgaris/uniflora species-complex (the bladder campions). I have focused on the effects of past and present hybridization both on a large scale ? over the whole of Europe ? and on a local scale. Silene vulgaris and S. LÄS MER
3. The lichen genus Candelariella in western North America
Sammanfattning : The lichen genus Candelariella comprises crustose to small squamulose members of the family Candelariaceae. The genus currently includes c. 50 species world-wide but few studies have treated the taxonomy within this group. In the present thesis the taxonomy of the genus in western North America is treated.

4. Genetic variation and population differentiation in the forest herb Lathyrus vernus (Fabaceae)
Sammanfattning : In the present thesis, I investigated patterns of genetic variation in the forest herb Lathyrus vernus (Fabaceae), using plant material from different-sized populations representing three geographically separated regions: central Europe, southern and central Sweden. My studies included presumably neutral or weakly selected characters (allozymes and leaflet shape) as well as characters that should be under strong directional selection (e. LÄS MER
5. Geographic Distribution of Intra-specific Variation in Widespread Eurasian boreo-nemoral Woodland Herbs
Sammanfattning : Many woodland plant species have huge distribution areas covering large parts of the Eurasian continent including areas that were glaciated during the last glacial period. In the present thesis, the geographic distribution of variation within such species is investigated and discussed in relation to glacial survival and post-glacial migration, dispersal ability, breeding system and levels of gene-flow between populations and related species, and various methods to measure and analyse genetic variation.
