Explaining hot spots of methane flux in a restored wetland: the role of water level, soil disturbance, and methanotrophy

open access: yesEnvironmental Research Letters
A high degree of uncertainty persists regarding current and future emissions of methane from both natural and constructed wetlands. Part of the problem is the existence of ‘hot spots’ of methane flux, which have not been clearly identified and studied at

Draft genome sequence of uncultured upland soil cluster gammaproteobacteria gives molecular insights into high-affinity methanotrophy [PDF]

open access: yes, 2017
Aerated soils form the second largest sink for atmospheric CH₄. A nearcomplete genome of uncultured upland soil cluster Gammaproteobacteria that oxidize CH₄ at 2.5 ppmv was obtained from incubated Antarctic mineral cryosols.

Constraining Greenhouse Gas Cycling and Emissions in Africa's Largest Humic Lake

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Humic tropical lakes and wetlands are globally important sources of atmospheric greenhouse gases (GHGs). However, mechanistic insight into GHG cycling in such systems remains limited—especially in understudied central Africa. To address this, here we measured high‐, falling‐, and low‐water seasonal concentrations and isotopic compositions of ...

Microbiological aspects of methane emission in a ricefield soil from the Camargue (France) : 2. Methanotrophy and related microflora [PDF]

open access: yes, 1996
Les principaux facteurs qui influencent l'activité méthanotrophe du sol (épaisseur du sol, humidité, addition d'engrais et dessiccation) ont été étudiés in vitro sur un sol de rizière de Camargue (France) afin de standardiser une méthode pour estimer l ...

Metagenomic Analysis of Thawing Permafrost Highlights Links Between Carbon and Nitrogen Cycling Processes in Abrupt Thaw Simulation

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Abrupt permafrost thaw events are projected to contribute up to 40% of permafrost carbon (C) release to the atmosphere. They involve sudden hydrological shifts within the soil column; however, the exact microbial functional pathway shifts induced by these events remain cryptic. To investigate how C and nutrient cycling processes differ in thaw

Modification and analysis of context-specific genome-scale metabolic models: methane-utilizing microbial chassis as a case study

open access: yesmSystems
Context-specific genome-scale model (CS-GSM) reconstruction is becoming an efficient strategy for integrating and cross-comparing experimental multi-scale data to explore the relationship between cellular genotypes, facilitating fundamental or applied ...

Spatial variations of community structures and methane cycling across a transect of Lei-Gong-Hou mud volcanoes in eastern Taiwan

open access: yesFrontiers in Microbiology, 2014
This study analyzed cored sediments retrieved from sites distributed across a transect of the Lei-Gong-Hou mud volcanoes in eastern Taiwan to uncover the spatial distributions of biogeochemical processes and community assemblages involved in methane ...

Structure and Spatial Heterogeneity of Chemosynthesis‐Based Deep‐Sea Archaeal and Bacterial Communities in Western South Atlantic

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We report an extensive investigation of prokaryotic communities from a methane cold‐seep area in the Western South Atlantic Ocean (Southern Brazil) employing a broad sample set, including three distinct geographic areas (A, C and E) across a depth gradient (up to 18 m below the seafloor) related to the sulfate–methane transition zone (SMTZ).

A metagenomics-based metabolic model of nitrate-dependent anaerobic oxidation of methane by Methanoperedens-like archaea

open access: yesFrontiers in Microbiology, 2015
Methane oxidation is an important process to mitigate the emission of the greenhouse gas methane and further exacerbating of climate forcing. Both aerobic and anaerobic microorganisms have been reported to catalyze methane oxidation with only a few ...

Ecological Feedbacks in the Earth System

open access: yesEarth's Future, Volume 14, Issue 2, February 2026.
Abstract Ecological feedbacks are fundamental features of the Earth system, affecting physical processes and chemical cycles. Our understanding of the interactions underlying these feedbacks at different spatial and temporal scales and the extent to which feedbacks affect Earth system functioning remains limited.
