Abstract Peatlands contain a significant fraction of global soil carbon, but how these reservoirs will respond to the changing climate is still relatively unknown. A picture variations in peat organic matter chemistry aid our ability gauge peatland response climate. The goal this research test hypotheses that (a) carbohydrate content, an indicator reactivity, increase with latitude and decrease mean annual temperatures, (b) while aromatic recalcitrance, vary inversely, (c) elevation have...
Core Ideas Soil organic matter chemical composition highlighted the inputs of varied vegetation communities in past. N is an indicator peat decomposition based on relationship functional group C and total N. Future surveys soil biogeochemical parameters should be pursued. Climate change subarctic region has increased rate inundation peatlands due to temperatures, precipitation, permafrost thaw. Increased may result community shifts, as documented a mire near Abisko, Sweden. The wet fen have...
Peatlands account for 15 to 30% of the world’s soil carbon (C) stock and are important controls over global nitrogen (N) cycles. However, C N concentrations known vary among peatlands contributing uncertainty inventories, but there few studies that relate peatland classification peat chemistry. We analyzed 436 cores sampled in 24 countries across six continents measured C, N, organic matter (OM) content at three depths down 70 cm. Sites were distinguished between northern (387) tropical (49)...
Abstract Peatlands play a critical role in the global carbon (C) cycle, encompassing ∼30% of 1,500 Pg C stored soils worldwide. However, this is vulnerable to climate and land‐use change. Ecosystem models predict impact perturbation on fluxes based soil pools, yet responses could vary markedly depending organic matter (SOM) chemistry. Here, we show that one SOM functional group responds strongly environmental factors predicts risk dioxide (CO 2 ) release from peatlands. The molecular...
