Permafrost contains about 50% of the global soil carbon. It is thought that the thawing of
permafrost can lead to a loss of soil carbon in the form of methane and carbon dioxide …

Carbon release due to permafrost thaw represents a potentially major positive climate
change feedback. The magnitude of carbon loss and the proportion lost as methane (CH4) …

In this study, a suite of complementary environmental geochemical analyses, including NMR
and gas chromatography-mass spectrometry (GC-MS) analyses of central metabolites …

We characterized peat decomposition at the Marcell Experimental Forest (MEF), Minnesota,
USA, to a depth of 2 m to ascertain the underlying chemical changes using Fourier transform …

Atmospheric concentrations of methane, a powerful greenhouse gas, have strongly
increased since 2007. Measurements of stable carbon isotopes of methane can constrain …

Thawing permafrost promotes microbial degradation of cryo-sequestered and new carbon
leading to the biogenic production of methane, creating a positive feedback to climate …

Permafrost thaw can alter the soil environment through changes in soil moisture, frequently
resulting in soil saturation, a shift to anaerobic decomposition, and changes in the plant …

Background During the acetogenic step of anaerobic digestion, the products of
acidogenesis are oxidized to substrates for methanogenesis: hydrogen, carbon dioxide and …

This study investigated the abundance, distribution, and composition of microbial
communities at the watershed scale in a boreal peatland within the Marcell Experimental …

The chemical transformations that govern storage, degradation, and loss of organic matter in
northern peatlands are poorly characterized, despite the significance of these peat deposits …
