A pan‐Arctic synthesis of CH 4 and CO 2 production from anoxic soil incubations
Abstract Permafrost thaw can alter the soil environment through changes in soil moisture, frequently resulting in soil saturation, a shift to anaerobic decomposition, and changes in the plant community. These changes, along with thawing of previously frozen organic material, can alter the form and m...
