Spatial Partitioning of Microbial Functional Potential Suggests Complex Nitrogen Cycling in a Subterranean Estuary

Environmental Microbiology, Volume 28, Issue 8, August 2026.
Microbial communities in a Mediterranean subterranean estuary show spatially structured nitrogen‐cycling potential across hydrochemical zones. Microbial properties, more than environmental variables, predict NO2− and NH4+ concentrations, highlighting their key role in controlling nitrogen transformations prior to submarine groundwater discharge ...

Effects of Fallow Season Water and Straw Management on Methane Emissions and Associated Microorganisms

Agronomy
The effects of fallow season water and straw management on methane (CH4) emissions during the fallow season and the subsequent rice-growing season are rarely reported, and the underlying microbial mechanisms remain unclear.

The methanol dehydrogenase gene, mxaF, as a functional and phylogenetic marker for proteobacterial methanotrophs in natural environments. [PDF]

PLoS ONE, 2013
The mxaF gene, coding for the large (α) subunit of methanol dehydrogenase, is highly conserved among distantly related methylotrophic species in the Alpha-, Beta- and Gammaproteobacteria.

Enhancing the Advanced Lake Biogeochemistry Model for Application to Thermokarst Lakes on Qinghai‐Tibet Plateau

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract Thermokarst lakes on Qinghai‐Tibet Plateau (QTP) are significant sources of greenhouse gas emissions, yet the underlying governing processes remain poorly understood. This study refines the Advanced Lake Biogeochemistry Model (ALBM) to characterize the unique environmental and biogeochemical processes of QTP thermokarst lakes. Key improvements

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

Scientific 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 ...

Diversity and Effect of Increasing Temperature on the Activity of Methanotrophs in Sediments of Fildes Peninsula Freshwater Lakes, King George Island, Antarctica

Frontiers in Microbiology, 2022
Global warming has a strong impact on polar regions. Particularly, the Antarctic Peninsula and nearby islands have experienced a marked warming trend in the past 50 years.

Vegetation Increases CH4 Emissions and Methanotroph Diversity in Marine Sediments

Global Change Biology, Volume 32, Issue 7, July 2026.
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.

Inhibition of methane oxidation by nitrogenous fertilizers in a paddy soil

Frontiers in Microbiology, 2012
Nitrogenous fertilizers are generally thought to have an important role in regulating methane oxidation. In this study, the effect of ammonium on methane oxidation activity was investigated in a paddy soil using urea at concentrations of 0, 50, 100, 200 ...

Scientific Opinion on waiving of the dog studies in the regulatory process of agrochemicals approval

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract Commission Regulation (EU) No. 283/2013 sets out the data requirements for pesticide active substances and includes short‐term oral toxicity testing in rodents (90‐day rat study) and non‐rodents (90‐day dog study) to support human health hazard assessment for pesticide active substances in the European Union (EU). However, the relevance of the

Specific microbial gene abundances and soil parameters contribute to C, N, and greenhouse gas process rates after land use change in Southern Amazonian Soils

Frontiers in Microbiology, 2015
Ecological processes regulating soil carbon (C) and nitrogen (N) cycles are still poorly understood, especially in the world’s largest agricultural frontier in Southern Amazonia.
