Mats Nilsson
Professor emeritus (Senior Advisor) at the Department of Forest Ecology and Management


I am a professor in Soil Science, Biogeochemistry. I do research and teaching on elemental cycling within ecosystems and exchange processes between ecosystems and the atmosphere with a focus on boreal and sub-arctic regions and in particular high latitude mires. I am co-PI of the Swedish contribution to the European Research Infra Structure Integrated Carbon Observatory Systems (ICOS ERIC) and station co-PI in the Swedish Infrastructure for Ecosystem Science (SITES).


My major research interest is the biogeochemistry of organic material with a focus on carbon cycling. The research on carbon cycling and exchange span from molecular to biosphere – atmosphere scales. Much of the research is conducted at high latitude mire and forest ecosystems. The ecosystem level research on high latitude mires aims at understanding the long term controls on the full carbon and green-house gas balance of mires. Much of this research is based at Degerö Stormyr, northern Sweden, being one of the most heavily instrumented high latitude mires with continuous measurements of the ecosystem-atmosphere exchange of both CO2 and CH4 and the discharge C-export since 2003. In addition we are maintaining several long-tem (>15 years) field manipulations to study the effects of anthropogenic perturbations (sulphur and nitrogen deposition) and changing climate (field deployed greenhouses and winter-time snow manipulation experiments) on mire ecology and biogeochemistry. Another focus area is the role of high-latitude mires for mercury transformations and eventually bioaccumulation in freshwater fish.

In close collaboration with Professor Jürgen Schleucher, Umeå University, I am using both standard and cutting-edge NMR (Nuclear Magnetic Resonance) Spectroscopy approaches to understand the role of organic matter molecular composition in controlling its degradation and long-term sequestration.

Much of the field-based research is undertaken within either of the two research infrastructures ICOS ERIC (Integrated Carbon Observatory Systems, European Research Infrastructure Consortium; and SITES (Swedish Infrastructure for Ecosystem Sciences;;
