Abstract:Despite their low primary production, ombrotrophic peatlands are important long-term sinks for atmospheric carbon due to even lower rates of litter decomposition. Litter decomposition can be affected by plant functional types (PFTs; Graminoids, Ericoids) and microhabitat (hummock, lawn), but the microhabitat context-dependency of PFT effects on decomposition processes remains poorly understood. We used a long-term (> 10 yr) plant removal experiment, in conjunction with the Tea Bag Index (TBI), to explore ho… Show more
