Carbon balance, biogeochemistry and vegetation changes in Sphagnum peatlands.
Inoculations with 14C and the C/N-quotient in the peat are used to estimate both present and past productivities, decay losses and carbon accumulation rates in different types of Sphagnum-dominated peatlands and its variation in relation to climatic and edaphic conditions. This line of research has been supported with special studies on the interaction between vascular plants and Sphagnum mosses in the competition for light and mineral nutrients. In the studies on changes in the mire vegetation I have compared old and present vegetation records and aerial photographs. All studies have been performed either in southern Sweden or in the Abisko area in northernmost Sweden.
