Tree stem methane emissions are regulated by site‐level biogeochemistry over species identity in Amazon floodplain forests

New Phytologist, Volume 251, Issue 1, Page 179-190, July 2026.
Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.

Methanotrophy below pH 1 by a new Verrucomicrobia species

Nature, 2007
Mud volcanoes, mudpots and fumaroles are remarkable geological features characterized by the emission of gas, water and/or semi-liquid mud matrices with significant methane fluxes to the atmosphere (10(-1) to 10(3) t y(-1)). Environmental conditions in these areas vary from ambient temperature and neutral pH to high temperatures and low pH.

Root oxygen mitigates methane fluxes in tropical peatlands

Environmental Research Letters, 2020
Tropical peatlands are a globally important source of methane, a potent greenhouse gas. Vegetation is critical in regulating fluxes, providing a conduit for emissions and regular carbon inputs.

Fully Organic Agroforestry Practices in Rice Cultivation: Effects on Soil Bacterial Microbiota, Soil Health and Grain Quality

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT Introduction Sustainable practices are increasingly recognised for benefiting soil biodiversity, health, and overall grain quality. This study examined a unique rice agroecosystem adopting fully organic practices and agroforestry through a seasonal characterisation of soil bacterial microbiota and physicochemical parameters.

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.

The Elbe Estuary Microbiome Shifts With Salinity and Discharge and Depends on Fresh Organic Matter and Nutrient Availability

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Microbial diversity within the Elbe Estuary was found to be more strongly governed by seasonal variability, salinity, and discharge than by spatial heterogeneity. Oligohaline regions sustain high diversity, while nutrient and redox conditions drive functional shifts.

Assessing methanotrophy and carbon fixation for biofuel production by Methanosarcina acetivorans [PDF]

Microbial Cell Factories, 2016
Methanosarcina acetivorans is a model archaeon with renewed interest due to its unique reversible methane production pathways. However, the mechanism and relevant pathways implicated in (co)utilizing novel carbon substrates in this organism are still not fully understood.

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

Foliar Contributions to Methane and Nitrous Oxide Exchange in Urban Green Roof Systems

GCB Bioenergy, Volume 18, Issue 6, June 2026.
Biochar amendment of extensive green roof substrates enhanced foliar methane (CH4) uptake (~3×) and reduced nitrous oxide (N2O) emissions across native and stonecrop vegetation. City‐scale extrapolation to Toronto's permitted green roof area indicates measurable, management‐sensitive non‐CO2 mitigation within urban green infrastructure systems ...

Off‐target metagenomics: Leveraging whole genome sequencing to study the bacteriome of the liverwort Calasterella californica

Applications in Plant Sciences, Volume 14, Issue 3, May-June 2026.
Abstract Premise The recovery of non‐target organism reads, especially when whole organisms are sampled, constitutes a great opportunity for studying microbial communities. The increase in whole genome sequencing feasibility and the development of new marker‐based pipelines enable the use of short reads to study bacterial communities associated with ...
