Abstract Peatlands contain one-third of soil carbon (C), mostly buried in deep, saturated anoxic zones (catotelm). The response catotelm C to climate forcing is uncertain, because prior experiments have focused on surface warming. We show that deep peat heating a 2 m-thick column results an exponential increase CH 4 emissions. However, this due solely processes and not degradation peat. Incubations only the top 20–30 cm from experimental plots higher production rates at elevated...

Fire is a major determinant of the global carbon (C) balance. While it known that C lost through organic matter combustion, effect fire has on soil biogeochemistry unclear. Studies investigating role greenhouse gas production (CO2 and CH4) have been conducted in forested grassland ecosystems, yet research wetlands limited. With their high potential for storage, wetland ecosystems are important cycling while simultaneously serving as largest single CH4 source world. Wildfires typically...

Peatlands are among the most important ecosystems in global carbon cycle. These wetlands store roughly one-third of terrestrial soil organic matter (SOM) and sources potent greenhouse gas methane (CH4) to atmosphere. Understanding cycling, particular CH4 dynamics, within peatland soils has implications for understanding biosphere-climate feedbacks. There is mounting evidence that under anaerobic conditions microbes can reduce terminal electron acceptors place oxygen soils. This microbial...
