Methane production in Minnesota peatlands.
Rates of methane production in Minnesota peats were studied. Surface (10- to 25-cm) peats produced an average of 228 nmol of CH(4) per g (dry weight) per h at 25 degrees C and ambient pH. Methanogenesis rates generally decreased with depth in ombrotrophic peats, but on occasion were observed to rise within deeper layers of certain fen peats. Methane production was temperature dependent, increas...
متن کاملMethane-cycling microbial communities and methane emission in natural and restored peatlands.
We addressed how restoration of forestry-drained peatlands affects CH(4)-cycling microbes. Despite similar community compositions, the abundance of methanogens and methanotrophs was lower in restored than in natural sites and correlated with CH(4) emission. Poor establishment of methanogens may thus explain low CH(4) emissions on restored peatlands even 10 to 12 years after restoration.

متن کاملModeling Ecosystem Processes and Peat Accumulation in Boreal Peatlands
Northern peatlands have accumulated up to about 450 Gt of carbon, mostly during the Holocene (the last 12,000 years) after the last glaciation (Gorham 1991; Clymo et al. 1998). Although northern peatlands have a relatively low average net accumulation rate (e.g., 19.4 g C m–2 year–1 in western interior Canada; Vitt et al. 2000), their extent, high-latitude location, and the large size of their ...
