“…The C accumulated in peat over centuries and millennia, because cold, acidic, and waterlogged conditions retard decomposition. Peatland C stocks are thought to be especially vulnerable to climate change because rising temperatures and associated hydrologic changes are expected to accelerate decomposition of surficial C stocks (He, He, & Hyvonen, 2016;Wilson et al, 2016), increase ecosystem respiration (Samson et al, 2018), and cause northern peatlands to become net sources of carbon to the atmosphere and exacerbating climatic warming (Gallego-Sala et al, 2018). Hence, peatlands may be one of the most important ecosystems providing feedbacks to global climate change (Bridgham, Pastor, Dewey, Weltzin, & Updegraff, 2008;Hilbert, Roulet, & Moore, 2000;Moore, Roulet, & Waddington, 1998).…”
