Evidence for nitrite-dependent anaerobic methane oxidation as a previously overlooked microbial methane sink in wetlands
Open accessAbstract
Significance: Given the current pressing need to more fully understand the methane cycle on Earth, in particular, unidentified sinks for methane, identifying and quantifying novel sinks for methane is fundamental importance. Here, we provide previously unidentified direct evidence for the nitrite-dependent anaerobic methane oxidation (n-damo) process as a previously overlooked microbial methane sink in wetlands by stable isotope measurements, quantitative PCR assays, and 16S rRNA and particulate methane monooxygenase gene clone library analyses. It is estimated that n-damo could consume 4.1–6.1 Tg of CH 4 m −2 per year in wetlands under anaerobic conditions, which is roughly 2–6% of current worldwide CH 4 flux estimates for wetlands. Given the worldwide increase in nitrogen pollution, this methane sink may become more important in the future.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
