Vegetation Increases CH<sub>4</sub> Emissions and Methanotroph Diversity in Marine Sediments. [PDF]
Seagrass meadows enhance carbon burial but also increase methane (CH4) emissions from marine sediments. The presence of seagrass modifies sediment properties, creating carbon‐rich environments characterized by higher carbon accumulation and CO2 fluxes, which stimulate CH4 production and lead to higher emissions.

Environmental Preferences and Functional Variations of Methanotrophs in Northeast Qinghai-Tibet Plateau Wetlands. [PDF]
Significant environmental preference between type I and type II methanotrophs is regulated by soil ion concentration (pH and electrical conductivity) in wetlands. Type II methanotrophs (Methylocystis, etc.) contributes more to soil methane oxidation than type I methanotrophs.

Responses of Soil Carbon and Nitrogen Cycling Gene Abundances to Winter Green Manure Incorporation in a Ratoon Rice System. [PDF]
Winter green manure incorporation is widely practised in southern China, yet its effect on soil carbon and nitrogen cycling gene abundances across a full ratoon rice cycle remains unclear.

Rethinking Termite Methane Emissions: Does the Mound Environment Matter? [PDF]
Many factors can influence the amount of methane (CH4) that is released from a termite mound. In this study, we tested how the external and internal environment of a termite mound impacts CH4 emission using field measurements of mounds in a Northern Australia savanna.

Species-level controls of foliar methane and nitrous oxide fluxes: roles of traits and microbes in temperate trees. [PDF]
Species‐level variation in temperate tree foliar greenhouse gas exchange, showing consistent foliar CH4 uptake, N2O emission, stronger CH4 uptake in fall leaves, and contrasting methanotroph communities between the high‐CH4‐oxidizing species Tilia americana and the low‐CH4‐oxidizing species Prunus virginiana. Summary The contribution of tree foliage to

Methane cycling microorganisms drive seasonal variation of methane emission in mangrove ecosystems. [PDF]
Coastal mangroves are one of the significant hotspots of natural methane (CH4) emissions, yet the seasonal dynamics of these emissions and the underlying microbial drivers remain poorly understood.

Molecular Fingerprint and Dominant Environmental Factors of Nitrite-Dependent Anaerobic Methane-Oxidizing Bacteria in Sediments from the Yellow River Estuary, China. [PDF]
Nitrite-dependent anaerobic methane oxidation (n-damo) is performed by "Candidatus Methylomirabilis oxyfera" (M. oxyfera), which connects the carbon and nitrogen global nutrient cycles. In the present study, M.

Ammonium Impacts Methane Oxidation and Methanotrophic Community in Freshwater Sediment
Lacustrine ecosystems are regarded as one of the important natural sources of greenhouse gas methane. Aerobic methane oxidation, carried out by methane-oxidizing bacteria, is a key process regulating methane emission.
