Soil domestication by rice cultivation results in plant-soil feedback through shifts in soil microbiota. [PDF]

, 2019
BackgroundSoils are a key component of agricultural productivity, and soil microbiota determine the availability of many essential plant nutrients.

Effects of Temperature on Mercury Methylation and Demethylation in Boreal Wetland Soils

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Wetlands are critical sites for methylmercury (MeHg) production, a neurotoxin that bioaccumulates in organisms and biomagnifies in aquatic food webs. Net MeHg production in wetland soil depends on the balance between microbially mediated MeHg production and the degradation of MeHg through both microbial and abiotic pathways.

Greenhouse Gas Dynamics From Created Wetlands of New Brunswick and Nova Scotia (Canada)

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Beginning in the 17th century, Acadian settlers dyked and drained salt marshes along the Bay of Fundy in Eastern Canada, transforming them into agricultural fields. Over the last ∼50 years, impoundments were created by building dykes to contain freshwater.

Structure and diversity of intestinal methanogens in black carp (Mylopharyngodon piceus), grass carp (Ctenopharyngodon idella) and water samples.

PLoS ONE
The present research investigation aims to examine the community features of methanogens in the intestinal tract of black and grass carp, as well as their association with methanogens in water samples.

Highly Variable Methane Production and Fluxes in a Hypereutrophic Lake Despite Uniform Bathymetry and Sediment Chemistry

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Hypereutrophic lakes support high sedimentation of labile organic carbon, promoting sediment anoxia and GHG potential production. Lakes with complex morphometry exhibit extensive spatial heterogeneity in sediment methane (CH4) and carbon dioxide CO2 dynamics. We wondered: do lakes with uniform bathymetry show low spatial variation in sediments'

Ecosystem‐Scale Methane Emissions From Peatlands of the Hudson Bay Lowlands

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Northern peatlands are important sources of methane (CH4) in the atmosphere. However, the magnitude of CH4 emissions and their response to environmental factors are poorly constrained within the Hudson Bay Lowlands (HBL), the largest contiguous peatland complex in North America. This study investigated seasonal (April–November) eddy covariance‐

Influent Wastewater Microbiota and Temperature Influence Anaerobic Membrane Bioreactor Microbial Community [PDF]

, 2016
Sustainable municipal wastewater recovery scenarios highlight benefits of anaerobic membrane bioreactors (AnMBRs). However, influences of continuous seeding by influent wastewater and temperature on attached-growth AnMBRs are not well understood. In this

Putative Analogs of Pyrite Suns Forming in Proglacial Alaska Mudflats

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Disc‐shaped pyrite suns of the Pennsylvanian age Anna Shale are thought to have formed where pressure restricted pyrite crystal growth to a flattened disc shape during diagenesis at the Anna Shale and the underlying Herrin coal boundary.

Acetogenic Methane‐Carbon Monoxide Comproportionation: An Exergonic but Unobserved Microbial Metabolism

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Microbial metabolism relies on redox reactions that exploit chemical disequilibria. While aerobic carbon oxidation, carbon fixation, and fermentation are well studied, the broader space of anaerobic carbon redox reactions remains underexplored.

The Dairy Ruminant Gut Microbiome: Profile, Responsiveness to Seasonality and Impact on Milk Quality

Environmental Microbiology, Volume 28, Issue 5, May 2026.
The dairy ruminant gut microbiome that is shaped by host and diet is affected by seasonality and rearing. These factors can impact dairy productivity and milk quality potentially through the gut microbiota. ABSTRACT The gut microbiome (GM) and particularly the rumen microbiome (RM) affect the ruminant health and they are associated with milk quality ...
