Microbial methanogenesis is a major source of the greenhouse gas methane (CH 4). It is the
final step in the anaerobic degradation of organic matter when inorganic electron acceptors …

Stable carbon and hydrogen isotope signatures of methane, water, and inorganic carbon
are widely utilized in natural gas systems for distinguishing microbial and thermogenic …

Atmospheric methane plays a major role in controlling climate, yet contemporary methane
trends (1982–2017) have defied explanation with numerous, often conflicting, hypotheses …

Net emissions of the potent GHG methane from ecosystems represent the balance between
microbial methane production (methanogenesis) and oxidation (methanotrophy), each with …

An important question in the context of climate change is to understand how CH4 production
is regulated in anoxic sediments of lakes and reservoirs. The type of organic carbon (OC) …

Inland water sediments receive large quantities of terrestrial organic matter,,,, and are
globally important sites for organic carbon preservation,. Sediment organic matter …

Recent discoveries of methyl-coenzyme M reductase–encoding genes (mcr) in uncultured
archaea beyond traditional euryarchaeotal methanogens have reshaped our view of …

Peatlands are a major source of atmospheric CH 4. The availability of terminal electron
acceptors largely affects the ratio of CO 2 to CH 4 formation under water-logged anoxic …

Rice straw is one of the major organic materials introduced to rice field soils and its
incorporation strongly enhances the emission of CH 4. We incubated unamended and straw …

Dam construction significantly impacts river hydrodynamics, subsequently influencing
carbon biogeochemical processes. However, the influence of hydrodynamic conditions on …
