Summary:
Sphagnum plants are major peat forming plants in circumpolar mires and they fix and store atmospheric carbon in peat. Due to water saturation of peat as well as hardly biodegradable substance in Sphagnum plants, Sphagnum peat can be an effective persistent carbon pool. Despite the importance of Sphagnum plants in global carbon dynamics, the carbon fixation rate of the Sphagnum community or photosynthetic activity of Sphagnum plants has not yet been accurately determined. Sphagnum leaves have a layered distribution, not only in a population but also within one individual plant. Thus the photosynthetic response to light shows a community type curve, i.e. the response curve did not saturate within the usual light condition of the actual Sphagnum community. Consequently, the response…
