6. Integrative taxonomy of birds : Studies into the nature, origin and delimitation of species
Sammanfattning : Species are the basic currency in biodiversity studies but what constitutes a species has long been controversial. A major breakthough was the insight that most systematists agree that species are segments of population lineages, and that multiple lines of evidence should be employed and integrated, a procedure called integrative taxonomy.

7. Automated image-based taxon identification using deep learning and citizen-science contributions
Sammanfattning : The sixth mass extinction is well under way, with biodiversity disappearing at unprecedented rates in terms of species richness and biomass. At the same time, given the currentpace, we would need the next two centuries to complete the inventory of life on Earthand this is only one of the necessary steps toward monitoring and conservation of species.

8. Basidiospore germination in ectomycorrhizal fungi : biochemical and ultrastructural studies with special reference to the taxon-specific germination induction in the genus Leccinum
Sammanfattning : .... LÄS MER
9. New Insights into the Evolution of Bryozoa- An Integrative Approach
Sammanfattning : Bryozoa is a group of aquatic, sessile invertebrates with circumglobal distribution and includes about 6000 recent species. Bryozoans have an indirect life cycle with a larval stage that settles and metamorphoses into the adult. LÄS MER
10. Phylogeny and Taxonomy of Childia (Acoela) : New characters for unraveling acoel phylogenies from molecules, ultrastructure, immunocytochemistry and confocal microscopy
Sammanfattning : This thesis presents a comprehensive phylogenetic and taxonomic study of an acoel subgroup, the Childiidae. Members of this taxon are characterized by well-developed male copulatory organs with conical/cylindrical stylets. LÄS MER
