Adding stable carbon isotopes improves model representation of the role of microbial communities in peatland methane cycling

Climate change is expected to have significant and uncertain impacts on methane (CH 4 ) emissions from northern peatlands. Biogeochemical models can extrapolate site‐specificCH 4 measurements to larger scales and predict responses of CH 4 emissions to environmental changes. However, these models include considerable uncertainties and limitations in representing CH 4 production, consumption, and transport processes. To improve predictions of CH 4...
