The anthropogenic emissions of carbon dioxide (CO2) into the atmosphere are held responsible for the current global warming experienced by the Earth. Given the amplified effect of warming in the northern regions, the main objective of this thesis is to assess the factors that could influence the organic matter (OM) degradation within a carbon-rich permafrost peatland. For this purpose, we studied the effect of biological and geochemical parameters, which are directly or indirectly influenced by climate change, on the degradation of OM. Field studies and experiments were carried out in discontinuous permafrost areas of Eastern Siberia and Sweden, along with laboratory experiments using substrates from these regions and from peatlands of NE E...
