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.

Restoration of forestry‐drained oligotrophic peatlands can bring climate change mitigation within a few decades

Restoration Ecology, Volume 34, Issue 4, May 2026.
Abstract Introduction Climate mitigation by peatland restoration is suggested, but data from restored forestry‐drained peatlands (FDP) is sparse. Studies using surrogate emission factors from pristine peatlands have indicated a long‐lasting warming effect of restoration of nutrient‐poor FDPs, while restoration‐specific studies are missing.

Viability of enhancing methanotrophy in terrestrial ecosystems exposed to low concentrations of methane

Communications Earth & Environment
Methane is a potent but relatively short-lived greenhouse gas, with anthropogenic and natural sources and rapidly increasing atmospheric concentrations.

Using Radon (222Rn) to Trace Variability in Greenhouse Gas Emission From Tree Stems Across Species, Seasons and Stem Heights

Ecohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Emissions from trees are an important component of the global methane (CH4) cycle, but their spatial origins (soil vs. in‐stem), transport pathways and environmental influences are not well constrained. To address these issues, this field study characterized spatial and temporal variability in stem emissions of biologically inert radon (222Rn),

Rapid Reactivation of Deep Subsurface Microbes in the Presence of C-1 Compounds

Microorganisms, 2015
Microorganisms in the deep biosphere are believed to conduct little metabolic activity due to low nutrient availability in these environments. However, destructive penetration to long-isolated bedrock environments during construction of underground waste

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.

Consumption of Methane and CO_2 by Methanotrophic Microbial Mats from Gas Seeps of the Anoxic Black Sea [PDF]

, 2007
The deep anoxic shelf of the northwestern Black Sea has numerous gas seeps, which are populated by methanotrophic microbial mats in and above the seafloor.

Dense bottom gravity currents and their impact on pelagic methanotrophy at oxic/anoxic transition zones [PDF]

, 2016
We show that inflows of oxygenated waters into sulfidic layers have a strong impact on biogeochemical transformation at oxic/anoxic transition zones. Taking the pelagic methane dynamics in the Gotland Basin as an example, we performed our studies when ...

Methane Mitigation:Methods to Reduce Emissions, on the Path to the Paris Agreement [PDF]

, 2020
The atmospheric methane burden is increasing rapidly, contrary to pathways compatible with the goals of the 2015 United Nations Framework Convention on Climate Change Paris Agreement.

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.
