Short summary
This study demonstrates the implications of Molinia caerulea colonization in Sphagnum peatland on the C fluxes by enhancing the CO2 uptake by photosynthesis (but which led to higher CO2 and CH4 emissions) and also on the parameters controlling it (by increasing the temperature sensitivity of the CH4 emissions). Furthermore, roots and litter of Molinia caerulea could provide additional substrates for C emissions and should be taken into account in further works.
