Sari Stark is a university researcher at the Arctic Centre at the University of Lapland, who investigates soil carbon and nitrogen cycling in tundra ecosystems and boreal and subarctic forests with special emphasis on soil decomposer microorganisms that are responsible for litter and soil organic matter decomposition. Recently the focus has been in studying effects of global change on northern ecosystems at different levels of grazing intensity, and how plant and soil responses interact to form ecosystem carbon balance that links back to global climate. sari.stark@ulapland.fi
