In this paper, we show that while microbial communities in peatland systems responded to manipulations of temperature and CO₂ concentrations, these changes were not associated with similar responses in peat decomposition rates over 3 years. It is unclear however from our current studies whether this functional resiliency over 3 years will continue over the longer time scales relevant to peatland ecosystem functions.mSystemse0033723https://www.ebi.ac.uk/biostudies/studies/S-EPMC10654087biostudies-literatureElevated temperature alters microbial communities, but not decomposition rates, during 3 years of <i>in situ</i> peat decomposition.PMC10654087Chanton JPSchadt CWKlingeman DMOleheiser KCHanson PJRoth SWGriffiths NACarrell AASeibert AKolka RKfalseElevated temperature alters microbial communities, but not decomposition rates, during 3 years of <i>in situ</i> peat decomposition.<h4>Importance</h4>Microbial community changes in response to climate change drivers have the potential to alter the trajectory of important ecosystem functions.
