Amazonia Wetland Methane Emission Decrease in 2023: Seasonal Forecasting of Global Wetlands Highlights Monitoring Targets in Critical Ecosystems

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.
Abstract In 2023, atmospheric methane (CH4) saw a decrease in the annual growth rate following record increases from 2020 to 2022. Recent changes in CH4 remain difficult to quantify due to delays in near‐real‐time (NRT) carbon cycle estimates. However, NRT models and subseasonal‐to‐seasonal (S2S) forecasting can provide the opportunity to analyze ...

Methanogens and Methanotrophs Show Nutrient-Dependent Community Assemblage Patterns Across Tropical Peatlands of the Pastaza-Marañón Basin, Peruvian Amazonia

Frontiers in Microbiology, 2020
Tropical peatlands are globally important carbon reservoirs that play a crucial role in fluxes of atmospheric greenhouse gases. Amazon peatlands are expected to be large source of atmospheric methane (CH4) emissions, however little is understood about ...

Phylogenomic Analysis of the Gammaproteobacterial Methanotrophs (Order Methylococcales) Calls for the Reclassification of Members at the Genus and Species Levels

Frontiers in Microbiology, 2018
The order Methylococcales constitutes the methanotrophs – bacteria that can metabolize methane, a potent greenhouse gas, as their sole source of energy.

Low Abundance of Methanotrophs in Sediments of Shallow Boreal Coastal Zones With High Water Methane Concentrations

Frontiers in Microbiology, 2020
Coastal zones are transitional areas between land and sea where large amounts of organic and inorganic carbon compounds are recycled by microbes. Especially shallow zones near land have been shown to be the main source for oceanic methane (CH4) emissions.

Isotopologue Ratios Identify 13C‐Depleted Biomarkers in Environmental Samples Impacted by Methane Turnover

Rapid Communications in Mass Spectrometry, Volume 39, Issue 22, 30 November 2025.
ABSTRACT Rationale The stable carbon isotopic composition (δ13C) of individual lipids is of great value in studying carbon cycling. Among those, microbial lipids in sediments impacted by high methane turnover stand out due to their uniquely depleted isotopic fingerprint.

Diversity and habitat preferences of cultivated and uncultivated aerobic methanotrophic bacteria evaluated based on pmoA as molecular marker

Frontiers in Microbiology, 2015
Methane-oxidizing bacteria are characterized by their capability to grow on methane as sole source of carbon and energy. Cultivation-dependent and –independent methods have revealed that this functional guild of bacteria comprises a substantial diversity

Variation in methanotroph-related proxies in peat deposits from Misten Bog, Hautes-Fagnes, Belgium [PDF]

, 2012
Methane emissions from peat bogs are strongly reduced by aerobic methane oxidising bacteria (methanotrophs) living in association with Sphagnum spp. Field studies and laboratory experiments have revealed that, with increasing water level and temperature,

Winter Methane Fluxes Over Boreal and Arctic Environments

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract Unprecedented warming of Arctic–boreal regions (ABR) has poorly understood consequences on carbon cycle processes. Limited winter data add uncertainty to annual methane (CH4) budgets. In this study, winter CH4 flux measurements were conducted using the snowpack diffusion gradient method over five ABR ecosystem types in Canada and Finland ...

Enhancement of Nitrous Oxide Emissions in Soil Microbial Consortia via Copper Competition between Proteobacterial Methanotrophs and Denitrifiers

Applied and Environmental Microbiology, 2020
Proteobacterial methanotrophs—groups of microorganisms that utilize methane as a source of energy and carbon—have been known to utilize unique mechanisms to scavenge copper, namely, utilization of methanobactin, a polypeptide that binds copper with high ...
