7/4/2023 0 Comments Download sphagnum moss![]() ![]() Water levels and the CO 2 treatment were found to interact, with the highest water level (1 cm below the surface) seeing the largest increase in dry weight under eCO 2 compared to ambient (400 ppm) concentrations. fallax, yielded the most biomass compared to S. Elevated CO 2 levels increased Sphagnum height and dry weight but the magnitude of the response differed among species. ![]() This study investigates the effects of elevated atmospheric CO 2 (eCO 2) (800 ppm) and hydrology on the growth of Sphagnum fallax, Sphagnum capillifolium and Sphagnum papillosum and greenhouse gas fluxes from moss–peat mesocosms. Sphagnum mosses comprise up to 90% of peat in the northern hemisphere but impacts of climate change on Sphagnum mosses are poorly understood, limiting development of sustainable peatland management and restoration. Peatlands are a critical carbon store comprising 30% of the Earth’s terrestrial soil carbon.
