Survival strategies of aerobic methanotrophs under hypoxia in methanogenic lake sediments

Environmental Microbiome
Background Microbial methane oxidation, methanotrophy, plays a crucial role in mitigating the release of the potent greenhouse gas methane from aquatic systems.

Kinetics of sulfate‐ and iron‐dependent anaerobic methane oxidation in freshwater lake sediment

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Anaerobic oxidation of methane (AOM) is a potentially important sink for methane in freshwater sediments. Assessing the contribution of AOM to methane budgets requires an understanding of AOM process kinetics, yet such information remains scarce.

Microbial impact on the isotope composition of methane in both thermal and hyperalkaline waters of central Greece [PDF]

, 2019
Introduction The different origins of methane can be subdivided in biogenic (either directly produced by microbial activity or deriving by decay of organic matter at T > 150\ub0C) and abiogenic (from pure inorganic reactions). Among the latter, one of

Genomic Reconstruction of an Uncultured Hydrothermal Vent Gammaproteobacterial Methanotroph (Family Methylothermaceae) Indicates Multiple Adaptations to Oxygen Limitation [PDF]

, 2015
Hydrothermal vents are an important contributor to marine biogeochemistry, producing large volumes of reduced fluids, gasses, and metals and housing unique, productive microbial and animal communities fueled by chemosynthesis.

Radiocarbon analysis reveals the contribution of aged terrestrial carbon to sedimentary methane cycling

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Methane (CH4) production in lacustrine sediments is known to be spatially heterogeneous, varying both horizontally and vertically. Porewater methane concentrations often differ between locations within a lake and with depth within the sediment profile. The drivers of this heterogeneity are often not well understood.

Bridging the Gap From Peat to Ponds: Terrestrial and Aquatic Greenhouse Gas Emissions in an Evolving Permafrost‐Associated Subarctic Peatland

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract Rapid permafrost thaw in peatlands transforms the subarctic landscape into a mosaic of ponds and peat soil, varying in moisture, carbon and nutrients, and time since thaw. As subarctic permafrost degrades, ponds emerge and mature and can gradually infill with Sphagnum peat.

Methane fluxes, microbial activities and community structures in a wet tundra of the Lena Delta [PDF]

, 2005
Wet tundra environments of the Arctic are natural sources of the climate relevant trace gas methane. The underlying biogeochemical processes are not yet well understood.

Stable isotope probing: Technical considerations when resolving ¹⁵N-labeled RNA in gradients [PDF]

, 2010
RNA based stable isotope probing (SIP) facilitates the detection and identification of active members of microbial populations that are involved in the assimilation of an isotopically labeled compound.

Sediment and rhizosphere microbes mediate seagrass growth responses to below‐ground nutrient limitation and enrichment

Journal of Ecology, Volume 114, Issue 4, April 2026.
This study suggests that below‐ground microbial communities are central to how seagrasses cope with nutrient variability. By providing field‐based, experimental evidence that both rhizosphere and bulk soil communities shape root growth, our work extends ecological understanding of plant–microbe interactions beyond terrestrial systems and into the ...

Methane‐Derived Carbon Contributes to Fish Biomass in a Deep, Eutrophic Reservoir

Freshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT Methanotrophic bacteria oxidise large amounts of biogenic methane produced in freshwater and bind the original methane carbon in their biomass. When these bacteria are consumed by other organisms, methane‐derived carbon enters food webs. Methane‐derived carbon can support a substantial part of invertebrate biomass in some freshwater ecosystems.
