Effects of experimental warming on Carbon sink function of a temperate pristine mire : The project PEATWARM

Abstract

Within the PEATWARM project, we use Sphagnum peatlands as a model to analyse their vulnerability to climate change using an experimental system (ITEX) that simulates in situ an increase in average temperature. We aim to determine the effects of temperature increase on the vegetation, the balance of above- and belowground gas fluxes (CO2 and CH4), the microbial diversity and activity in Sphagnum mosses and in peat, and the dynamics of labile and recalcitrant organic matter of peat. The ultimate objective is the creation of a biogeochemical model of C coupled with N and S cycles that includes interactions between these key compartments. Keywords: Global warming, C, N, S cycles, ITEX manipulations, ecosystem structure and function, biogeochemical model of C.
