My research is on interactions between plants, microbes, atmosphere and soil, mainly in terrestrial ecosystems. I study above‑ and belowground processes in non-managed arctic/alpine, temperate and tropical ecosystems, supplemented with experimental manipulations in growth chambers, greenhouses, nurseries and the field.
The aim is to reveal the consequences of environmental changes such as global warming, nitrogen deposition or changed land use on processes involving soils, plants and microbes, from root/leaf level to ecosystem level. Current activities focus on experimental studies of the effects of climate change (global warming) on nutrient and carbon cycling in arctic and temperate ecosystems. For instance, plant performance, nutrient availability, plant nitrogen acquisition and the emission of greenhouse gases from arctic and temperate heath vegetation is studied using long-term climate change related field plots.
As the responsible for advanced isotope ratio mass spectrometers and cavity-ring down laser instruments in our laboratory, stable isotope methodology is frequently used in my research. By the use of stable isotopes (13C and 15N), both at natural abundance and enrichment levels, one of my main research aims is to increase our understanding of plant uptake of soil nitrogen in various forms, in symbiosis and/or competition with soil microorganisms, and to investigate the role of mycorrhizal fungi in plant nutrition, especially in non-managed ecosystems.
My research group is one of the main players internationally in the attempts to reveal the effects of climate change on decisive biogeochemical and physiological processes and key organisms in natural ecosystems. Several long-term ecosystem manipulation experiments in N Sweden and Greenland, led by me, constitute a permanent attraction for post docs, ph.d and master students, both nationally and internationally. My emphasis on the coupling between above-and belowground processes, biogeochemistry and plant physiological ecology in natural or low-management ecosystems in the Arctic is probably unique in a Danish university context.
