Warming impacts on boreal fen CO2 exchange under wet and dry conditions

AM Laine, P Mäkiranta, R Laiho… - Global change …, 2019 - Wiley Online Library
Northern peatlands form a major soil carbon (C) stock. With climate change, peatland C
mineralization is expected to increase, which in turn would accelerate climate change. A …

Differential response of carbon fluxes to climate in three peatland ecosystems that vary in the presence and stability of permafrost

ES Euskirchen, CW Edgar, MR Turetsky… - Journal of …, 2014 - Wiley Online Library
Abstract Changes in vegetation and soil properties following permafrost degradation and

Sensitivity of CO2 Exchange of Fen Ecosystem Components to Water Level Variation

T Riutta, J Laine, ES Tuittila - Ecosystems, 2007 - Springer
A bstract Climate change is predicted to bring about a water level (WL) draw-down in boreal
peatlands. This study aimed to assess the effect of WL on the carbon dioxide (CO 2) …

A 12-year record reveals pre-growing season temperature and water table level threshold effects on the net carbon dioxide exchange in a boreal fen

M Peichl, M Öquist, MO Löfvenius… - Environmental …, 2014 - iopscience.iop.org
This study uses a 12-year time series (2001–2012) of eddy covariance measurements to
investigate the long-term net ecosystem exchange (NEE) of carbon dioxide (CO 2) and inter …

Effects of temperature rise and water-table-level drawdown on greenhouse gas fluxes of boreal sedge fens

M Pearson, T Penttilä, L Harjunpää, R Laiho, J Laine… - 2015 - jukuri.luke.fi
As potential outcomes of climate change, we examined the effects of environmental warming
and drying on instantaneous CO2, CH4 and N2O fluxes in three sedge fens situated in the …

Lowering water table reduces carbon sink strength and carbon stocks in northern peatlands

MJ Kwon, A Ballantyne, P Ciais, C Qiu… - Global change …, 2022 - Wiley Online Library
Peatlands at high latitudes have accumulated> 400 Pg carbon (C) because saturated soil
and cold temperatures suppress C decomposition. This substantial amount of C in Arctic and …

Low impact of dry conditions on the CO2 exchange of a Northern-Norwegian blanket bog

M Lund, JW Bjerke, BG Drake… - Environmental …, 2015 - iopscience.iop.org
Northern peatlands hold large amounts of organic carbon (C) in their soils and are as such
important in a climate change context. Blanket bogs, ie nutrient-poor peatlands restricted to …

Stimulation of both photosynthesis and respiration in response to warmer and drier conditions in a boreal peatland ecosystem

LB Flanagan, KH Syed - Global Change Biology, 2011 - Wiley Online Library
Peatland ecosystems have been consistent carbon (C) sinks for millennia, but it has been
predicted that exposure to warmer temperatures and drier conditions associated with climate …

Climate change reduces the capacity of northern peatlands to absorb the atmospheric carbon dioxide: The different responses of bogs and fens

J Wu, NT Roulet - Global Biogeochemical Cycles, 2014 - Wiley Online Library
The carbon (C) storage of northern peatlands is equivalent to~ 34–46% of the~ 795 T g C
currently held in the atmosphere as CO2. Most studies report that northern peatlands are a …

Warming response of peatland CO2 sink is sensitive to seasonality in warming trends

M Helbig, T Živković, P Alekseychik, M Aurela… - Nature Climate …, 2022 - nature.com
Peatlands have acted as net CO2 sinks over millennia, exerting a global climate cooling
effect. Rapid warming at northern latitudes, where peatlands are abundant, can disturb their …
