16. Genetic variation, clonal diversity and breeding system in sedges (Carex)
Sammanfattning : In this thesis I investigate genetic variation in clonal plants within the wind-pollinated plant family Cyperaceae and, in particular, in species of Carex. Clonal diversity and the spatial distribution of clones (genets) within populations was investigated in Carex bigelowii (in Iceland and Scandinavia) and C. LÄS MER
17. Differential object marking in South Saami
Sammanfattning : This licentiate thesis investigates the case and the syntactic position of the direct object in South Saami. The focus is on plural direct objects, which have Differential Object Marking, a phenomenon in which the case alternates between different types of direct objects. LÄS MER
18. The genus Xanthoria (Fr.) Th.Fr. in North America
Sammanfattning : The lichenized ascomycete genus Xanthoria (Fr.) Th.Fr. (Teloschistaceae) in continental United States and Canada is revised. LÄS MER
19. Geographic differentiation and population history in Silene dioica and S. hifacensis: variation in chloroplast DNA and allozymes
Sammanfattning : In this thesis I used allozymes and PCR-RFLP analysis of chloroplast DNA (cpDNA) to investigate geographic differentiation within the widespread Silene dioica (L.) Clairv. (Caryophyllaceae) and the narrowly-distributed S. hifacensis Rouy ex Willk. LÄS MER
20. 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
