Peatlands have acted as C-sinks for millennia, storing large amounts of carbon, of which a significant amount is yearly released as methane (CH 4 ).  Sphagnum  mosses are a key genus in many peat ecosystems and these mosses live in close association with methane-oxidizing and nitrogen-fixing microorganisms. To disentangle mechanisms which may control  Sphagnum -associated methane-oxidation and nitrogen-fixation, we applied four treatments to  Sphagnum  mosses from a pristine peatland in Finland: nitrogen fertilization, phosphorus fertilization, CH 4  addition and light. N and P fertilization resulted in nutrient accumulation in the moss tissue, but did not increase  Sphagnum  growth. While net CO 2  fixation rates remained unaffected in the N and P treatment, net CH 4  emissions decreased because of enhanced CH 4  oxidation. CH 4  addition did not affect  Sphagnum  performance in the present set-up. Light, however, clearly stimulated the activity of associated nitrogen-fixing and methane-oxidizing microorganisms, increasing N 2  fixation rates threefold and CH 4  oxidation rates fivefold. This underlines the strong connection between  Sphagnum  and associated N 2  fixation and CH 4  oxidation. It furthermore indicates that phototrophy is a strong control of microbial activity, which can be directly or indirectly.

Microbial nitrogen fixation and methane oxidation are strongly enhanced by light in Sphagnum mosses
