11. Assessing and monitoring genetic patterns for conservation purposes with special emphasis on Scandinavia
Sammanfattning : Genetic variation is essential for biological evolution, for maintaining viability of populations, and to ensure ecosystem resilience. Increased human exploitation and environmental change result in rapid loss of biological variation, including genetic diversity. LÄS MER
12. European Black Grouse : MHC Genetic Diversity and Population Structure
Sammanfattning : Black grouse Tetrao tetrix is a bird species composed of large, continuous as well as severely reduced and fragmented populations, making it an optimal species to investigate how genetic diversity is affected by habitat fragmentation. I have focused on genetic diversity in the Major Histocompatibility Complex (MHC) to measure the ability of the black grouse to respond to environmental changes. LÄS MER
13. 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
14. Hidden Diversity Revealed : Genomic, Transcriptomic and Functional Studies of Diplomonads
Sammanfattning : The diplomonads are a diverse group of eukaryotic microbes found in oxygen limited environments such as the intestine of animals were they may cause severe disease. Among them, the prominent human parasite Giardia intestinalis non-invasively colonizes the small intestine of humans and animals where it induces the gastrointestinal disease giardiasis. LÄS MER
15. 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
