Kjærandsen, Jostein

My research interest is to study patterns of insect diversity in a taxonomic and biosystematic framework. I am further interested in the functional evolution of their various organs such as genitalia and wings and how they are used in mating-systems and for species recognition. My research is contributing to build a taxonomic knowledge base of the Holarctic fauna of fungus gnats (Diptera, Sciaroidea). With some 1000 Nordic species, fungus gnats play an important role in the ecosystem of the boreal taiga.
