Journal ArticleDOI
Climate-sensitive northern lakes and ponds are critical components of methane release
TL;DR: In this article, a synthesis of the greenhouse gas methane from lakes and ponds is presented in the boreal region and northwards of the United States, where almost half of these waters are located.
Journal ArticleDOI
Seasonal patterns and controls on net ecosystem CO2 exchange in a boreal peatland complex
TL;DR: In this paper, seasonal patterns of net ecosystem exchange (NEE) of CO2 in a diverse peatland complex underlain by discontinuous permafrost in northern Manitoba, Canada, as part of the Boreal Ecosystems Atmosphere Study (BOREAS), were measured.
Journal ArticleDOI
Fine root dynamics and trace gas fluxes in two lowland tropical forest soils.
Whendee L. Silver,Andrew W. Thompson,Megan E. McGroddy,Ruth K. Varner,J. D. Dias,Hudson Silva,Patrick M. Crill,Michael Keller +7 more
TL;DR: In this article, fine root dynamics have the potential to contribute significantly to ecosystem-scale biogeochemical cycling, including the production and emission of greenhouse gases, and this is particularly true in...
Journal ArticleDOI
Temperature and peat type control CO2 and CH4 production in Alaskan permafrost peats
Claire C. Treat,Wilfred M. Wollheim,Ruth K. Varner,A. S. Grandy,Julie Talbot,Stephen E. Frolking +5 more
TL;DR: Temperature, moisture, organic matter, and microbial controls on soil organic carbon (SOC) losses following permafrost thaw in peat soils across Alaska, and carbon dioxide and methane emissions varied depending on the peat type and peat decomposition stage rather than thermal state.
Journal ArticleDOI
Multiyear measurements of ebullitive methane flux from three subarctic lakes
TL;DR: Ebullition (bubbling) from small lakes and ponds at high latitudes is an important yet unconstrained source of atmospheric methane (CH4) Small water bodies are most abundant in permanently frozen.
