1. Spikemoss patterns : Systematics and historical biogeography of Selaginellaceae
Sammanfattning : Selaginellaceae, spikemosses, is a heterosporous plant family belonging to the lycophytes. With an estimated age of some 350 million years, the family is historically important as one of the oldest known groups of vascular plants. Selaginellaceae is herbaceous with a worldwide distribution. However, the majority of the ca. LÄS MER
2. Patterns and Processes of Evolution in Sundaland
Sammanfattning : Biodiversity in the tropics is disproportionately high compared to other habitats, and also under disproportionate threat from human impact. It is necessary to understand how this diversity evolved and how it is partitioned across space in order to preserve it. LÄS MER
3. Population Genetic Structure of Black Grouse (Tetrao tetrix) : From a Large to a Fine Scale Perspective
Sammanfattning : Black grouse (Tetrao tetrix) is a bird species with a lek mating system found in the Palearctic boreal taiga. It is assumed that it has a continuous distribution along Scandinavia and Siberia, whereas in Central Europe it has declined during the last decades. LÄS MER
4. Inferring Ancestry : Mitochondrial Origins and Other Deep Branches in the Eukaryote Tree of Life
Sammanfattning : There are ~12 supergroups of complex-celled organisms (eukaryotes), but relationships among them (including the root) remain elusive. For Paper I, I developed a dataset of 37 eukaryotic proteins of bacterial origin (euBac), representing the conservative protein core of the proto-mitochondrion. LÄS MER
5. Contributions to the understanding of diversity and evolution in the genus Coreomyces
Sammanfattning : The Laboulbeniales is an order of enigmatic ascomycete fungi that are obligate microscopic parasites of arthropods, which are usually non-detrimental. They typically display a high degree of host specificity, and the genus Coreomyces, which is the recurring theme of this thesis, is no exception. LÄS MER
