From:Earth System Science Data (Vol. 14, Issue 1) Peer-ReviewedPast efforts to synthesize and quantify the magnitude and change in carbon dioxide (CO.sub.2) fluxes in terrestrial ecosystems across the rapidly warming Arctic-boreal zone (ABZ) have provided valuable information but...

From:Biogeosciences (Vol. 18, Issue 16) Peer-ReviewedPristine boreal mires are known as substantial sinks of carbon dioxide (CO.sub.2) and net emitters of methane (CH.sub.4). Bogs constitute a major fraction of pristine boreal mires. However, the bog CO.sub.2 and CH.sub.4...

We measured methane ebullition from a patterned boreal bog situated in the Siikaneva wetland complex in southern Finland. Measurements were conducted on water (W) and bare peat surfaces (BP) in three growing seasons...

Rain-fed peatlands are dominated by peat mosses (Sphagnum sp.), which for their growth depend on nutrients, water and CO.sub.2 uptake from the atmosphere. As the isotopic composition of carbon (.sup.12,13 C) and...

From:Biogeosciences (Vol. 18, Issue 6) Peer-ReviewedBoreal forest soils are globally an important sink for methane (CH.sub.4 ), while these soils are also capable of emitting CH.sub.4 under favourable conditions. Soil wetness is a well-known driver of CH.sub.4 flux, and...

From:Biogeosciences (Vol. 17, Issue 3) Peer-ReviewedVegetation and hydrology are important controlling factors in peatland methane dynamics. This study aimed at investigating the role of vegetation components, sedges, dwarf shrubs, and Sphagnum mosses, in methane fluxes...

Water flow controls the spatial variability of methane emissions in a northern valley fen ecosystem.
Northern peatlands are projected to be crucial in future atmospheric methane (CH.sub.4) budgets and have a positive feedback on global warming. Fens receive nutrients from catchments via inflowing water and are more... -
From:Earth System Science Data (Vol. 13, Issue 7) Peer-ReviewedMethane (CH.sub.4) emissions from natural landscapes constitute roughly half of global CH.sub.4 contributions to the atmosphere, yet large uncertainties remain in the absolute magnitude and the seasonality of emission...

From:Biogeosciences (Vol. 17, Issue 22) Peer-ReviewedCurrent peatland models generally treat vegetation as static, although plant community structure is known to alter as a response to environmental change. Because the vegetation structure and ecosystem functioning are...

From:Biogeosciences (Vol. 14, Issue 2) Peer-ReviewedIn boreal bogs plant species are low in number, but they differ greatly in their growth forms and photosynthetic properties. We assessed how ecosystem carbon (C) sink dynamics were affected by seasonal variations in the...
