Land Cover and Hydrology Regulate Riverine Carbon Emissions From Subarctic Catchments

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Streams transport carbon (C) and nutrients across the terrestrial‐aquatic interface and are significant sources of methane (CH4) and carbon dioxide (CO2) to the atmosphere. Climate‐induced changes in vegetation and hydrology increase the export of dissolved organic carbon (DOC) from terrestrial to aquatic ecosystems, but the impact of these ...

Unraveling the depth-dependent causal dynamics of methanogenesis and methanotrophy in a high-latitude fen peatland

Environmental Research Letters
The dynamics of methane (CH _4 ) cycling in high-latitude peatlands through different pathways of methanogenesis and methanotrophy are still poorly understood due to the spatiotemporal complexity of microbial activities and biogeochemical processes ...

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

, 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.

Increase in CH4 Emissions in a Pantanal Wetland Lagoon Due to Extreme Drought and Sediment Exposure

International Review of Hydrobiology, Volume 110, Issue 2, Page 90-99, December 2025.
ABSTRACT The Pantanal, one of the largest wetlands on Earth, stores substantial carbon in its diverse ecosystems but faces increasing threats, such as fires, poor soil management, deforestation, and climate change impacts that may elevate CH₄ emissions.

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

Environmental 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

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

, 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 ...

Influence of Plant Genotype on Nodule‐Associated Bacterial Community Composition and Function in Seasonal Field Pea Varieties

Legume Science, Volume 7, Issue 4, December 2025.
ABSTRACT Legume root nodules host symbiotic rhizobia that are essential for nitrogen fixation but also harbor diverse non‐rhizobial taxa that remain poorly characterized. Field pea (Pisum sativum) cultivars adapted to distinct seasonal growth (spring and winter) offer an opportunity to explore whether host genotype influences nodule‐associated ...

Microbial Diversity of the Surface of Polypropylene and Low Density Polyethylene‐Based Materials (Plastisphere) From an Area Subjected to Intensive Agriculture

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Bacterial communities colonizing LDPE and PP plastispheres from an intensive agriculture landfill exhibited differences in their taxonomic composition and structure. A predictive metagenomic analysis suggested physical and biological degradation of LDPE, in addition to degradation of plastic additives and herbicides by microorganisms present in both ...

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

mSystems
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

Frontiers 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 ...
