Biogeochemistry in the arctic – processes, controls and sensitivity to ”global change”

Updated 2003-04-24

The research addresses questions of drivers and controls of biogeochemical (nutrient and carbon) cycling in arctic ecosystems. The focus is, first, on interactions between plants, microbes and the soil organic matter and the project explores possible, periodic competition for nutrients between soil microbes and plants and the mechanisms of net nutrient mineralisation coupled with plant nutrient uptake. Another focus is on how pools and fluxes of carbon and nutrients in, and between, major ecosystem components are likely to be affected if the arctic climate changes (”the greenhouse effect”). This research is based on data collected from experimental manipulations of arctic ecosystems that have lasted for close to, or over, a decade.
