1. The spatial structure of genetic and morphometric variation in Corylus avellana (Betulaceae): pattern and scale
Sammanfattning : 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. LÄS MER
2. 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
3. Variation in Silene vulgaris and S. uniflora (Caryophyllaceae): genetic diversity, gene flow and habitat selection
Sammanfattning : 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. LÄS MER
4. Systematics of polyploid Dactylorhiza (Orchidaceae) - genetic diversity, phylogeography and evolution
Sammanfattning : This thesis examines genetic variation in allotetraploids of the Dactylorhiza incarnata/maculata polyploid complex in different parts of Europe. The molecular markers used were AFLPs, allozymes, ITS, nuclear microsatellites and plastid DNA markers. LÄS MER
5. Variation in Pseudorchis albida s.l. (Orchidaceae) and Carex capitata s.l. (Cyperaceae) : Morphology, genetic diversity, ecology and systematics
Sammanfattning : In the Scandinavian flora, several species-pairs where one member is an alpine species andthe other is a closely related lowland species, have been described. The aim of this studywas to investigate two such examples, viz. Pseudorchis albida s.s. LÄS MER
