11. Vanadate and Peroxovanadate Complexes of Biomedical Relevance : A speciation approach with focus on diabetes
Abstract : Diabetes mellitus is one of the most threatening epidemics of modern times with rapidly increasing incidence. Vanadium and peroxovanadium compounds have been shown to exert insulin–like actions and, in contrast to insulin, are orally applicable. However, problems with side–effects and toxicity remain.

12. Speciation genomics in Ficedula flycatchers
Abstract : Understanding what evolutionary processes have shaped patterns of genomic differentiation between species is a major aim of speciation genomics. However, disentangling the role of different processes that generate similar patterns remains a substantial challenge. READ MORE

13. Analysis and speciation of organic phosphorus in environmental matrices : Development of methods to improve 31P NMR analysis
Abstract : Phosphorus (P) is an essential element for life on our planet. It is central in numerous biochemical processes in terrestrial and aqueous ecosystems including food production; and it is the primary growth-limiting nutrient in some of the world’s biomes. READ MORE

14. On Speciation in Birds – Genomic Signatures across Space and Time
Abstract : The process of speciation is a cornerstone in evolutionary biology. In Darwin’s On the Origin of Species, he described how he imagined that a new species would evolve to fill an empty niche. This focus on ecology shifted with Mayr towards the importance of isolation, and for many decades the geographic modes of speciation were debated. READ MORE

15. Biodiversity in Swedish Cyprinid Fish: Insights Into Processes of Divergence
Abstract : Uncovering and understanding the processes that have led to the biological diversity we observe today are of fundamental interest in biology. Since direct observation of speciation is usually impossible, knowledge about the processes behind species formation can be gathered by studying mutations, natural/sexual selection, and genetic drift.
