6. Diversity Underfoot : Systematics and Biogeography of the Dictyostelid Social Amoebae
Abstract : Dictyostelids (Amoebozoa) are a group of social amoebae consisting of approximately 150 species, which are found in terrestrial habitats worldwide. They are divided into eight major clades based on molecular phylogeny, and within these clades are many species complexes. READ MORE

7. Species Limits, and Evolutionary History of Glassfrogs
Abstract : Recognizing the mechanisms of speciation and the limits of species is essential to understand the origin of biodiversity and how to conserve it. The general aims of my investigations during my doctoral studies were two-fold: to study evolutionary patterns and processes, and to provide specific and superspecific taxonomic classifications that try to reflect evolutionary history.

8. Climbing the Trichoptera Tree : Investigations of Branches and Leaves
Abstract : The Trichoptera (caddisflies) is the largest of the primary aquatic insect orders, currently including more than 13,500 species. With more than 100 species new to science described annually, the known caddisfly diversity is rapidly increasing. In the first four papers of this Thesis, a total of 22 species new to science are described. READ MORE

9. On Ingeae Systematics of synandrous mimosoids
Abstract : Background: The Ingeae tribe (Caesalpiniodeae, Fabaceae) has a long history of taxonomic complexity with genera being merged and split, and many species with former placements in several different genera. Moreover, phylogenetic studies have shown that the tribe is non-monophyletic with the genus Acacia (of tribe Acacieae) nested within Ingeae. READ MORE

10. Contributions to the understanding of diversity and evolution in the genus Coreomyces
Abstract : 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. READ MORE
