Major interests are food web ecology and “ecological stoichiometry” in aquatic food-webs, but I have also papers and ongoing projects on genetic structure of arctic crustaceans as well as studies of the cellular evolution and regulation of growth rate via rDNA and RNA in various organisms. I have also ongoing studies on climatic effects on element cycling and biota in catchments as well as the biological effects of UV-radiation, but my core research for the past ten years has been on the reciprocal regulation of the key elements carbon, nitrogen and phosphorus. This research is done in concert with is an international team, where all aspects from cellular regulation of growth rate and thus the cellular fate of carbon, via experiments and models on food web efficiency in terms of carbon transfer up to global scaling of biotic C-fluxes.
