Soil CO2 emission and soil attributes associated with the microbiota of a sugarcane area in southern Brazil

open access: yesScientific Reports, 2021
The spatial structure of soil CO2 emission (FCO2) and soil attributes are affected by different factors in a highly complex way. In this context, this study aimed to characterize the spatial variability patterns of FCO2 and soil physical, chemical, and ...

Season and No-Till Rice Crop Intensification Affect Soil Microbial Populations Involved in CH4 and N2O Emissions

open access: yesFrontiers in Soil Science, 2022
Rice is an important source of methane (CH4) and other crops may be sources of nitrous oxide (N2O), both of which are powerful greenhouse gases. In Uruguay, irrigated rice rotates with perennial pastures and allows high productivity and low environmental

Methane‐Driven Arsenic Biogeochemical Cycling in Deep‐Sea Cold Seeps: Implications for Oceanic Arsenic Geochemistry

open access: yesGeophysical Research Letters, Volume 52, Issue 16, 28 August 2025.
Abstract Arsenic accumulation in seafloor cold seeps is poorly understood. Here, we investigate the interplay between arsenic and methane biogeochemical cycles at the Haima cold seep, South China Sea. Geochemical analyses showed elevated arsenic levels in seep sediments, primarily as sulfide‐bound forms, with strong correlations between dissolved ...

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.

Sustained Green Manure‐Rice Rotations Can Mitigate Methane Emissions by Enhancing Microbial Methane Oxidation in Southern China

open access: yesEarth's Future, Volume 13, Issue 8, August 2025.
Abstract Green manure (GM) enhances the ecological services in agricultural ecosystems, including soil health and carbon sequestration. However, its effect on regional methane (CH4) emissions from paddy fields is unclear. Here we clarify the impacts of GM rotation by combining process‐based modeling with microbial gene abundance information and ...

Visible-Light Photochromic Properties of an Inorganic-Organic Phosphomolybdic Acid/Polythiophene Hybrid Thin Film

open access: yesChemistry
A visible-light photochromic hybrid film was synthesized based on combining phosphomolybdic acid (PMoA) with the polythiophene (PTh) matrix. The microstructure and photochromic properties of the materials were analyzed through atomic force microscopy ...

Aquatic plant surface as a niche for methanotrophs

open access: yesFrontiers in Microbiology, 2014
This study investigated the potential local CH4 sink in various plant parts as a boundary environment of CH4 emission and consumption. By comparing CH4 consumption activities in cultures inoculated with parts from 39 plant species, we observed ...

Biogeographic Patterns and Ecological Roles of Microorganisms in Sediments Along an Estuarine Salinity Gradient

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 4, August 2025.
From the river coastal to the adjacent sea waters, the diversity characteristics, community assembly processes, functional potential and community compositions of sedimentary microbial communities exhibit significant changes with increasing salinity levels.

Nitrogen Redox Controls on Greenhouse Gas Production in Yedoma Taliks

open access: yesGlobal Change Biology, Volume 31, Issue 7, July 2025.
Arctic Yedoma permafrost holds large carbon and nitrogen pools that, when thawed, undergo microbially mediated processes that release greenhouse gases like methane and nitrous oxide. We analyzed seasonal shifts in microbial community dynamics and geochemistry in deep thawed soils (talik) and found year‐round methane production, with limited winter ...

Marine organic aerosol at Mace Head: effects from phytoplankton and source region variability [PDF]

open access: yesAtmospheric Chemistry and Physics
Organic aerosol (OA) is recognized as a significant component of particulate matter (PM), yet their specific composition and sources, especially over remote areas, remain elusive due to the overall scarcity of high-resolution online data.
