Global Comparison of Aqueous Geochemistry and Dissolved H2/CH4 in Continental Low Temperature Serpentinization–Influenced Environments

Hydrological Processes, Volume 40, Issue 3, March 2026.
Conceptual diagram of hydrological and geochemical processes within the Santa Elena Ophiolite, Costa Rica. It highlights watershed cross‐sections, soil genesis, hyperalkaline Type II waters (pH > 11.6) with calcite crust and trapped H2/CH4 gases, seepage into surface waters, storm‐impacted stream profiles, weathered vs.

Seasonal dynamics of methane in the water column of two subtropical lakes differing in trophic status

Brazilian Journal of Biology
Alterations in methane concentration in the water column of aquatic systems is closely linked to the processes of production and consumption of this gas, i.e., methanogenesis and methanotrophy respectively. The aim of this research is to evaluate methane

A Genome-Scale Metabolic Model for Methylococcus capsulatus (Bath) Suggests Reduced Efficiency Electron Transfer to the Particulate Methane Monooxygenase

Frontiers in Microbiology, 2018
Background: Genome-scale metabolic models allow researchers to calculate yields, to predict consumption and production rates, and to study the effect of genetic modifications in silico, without running resource-intensive experiments.

Unraveling the effects of wet and dry areas on carbon emissions in an intermittent Mediterranean stream

Limnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Stream hydrological regimes are increasingly altered by water extraction, land‐use change, and climate change, leading to prolonged streambed desiccation in many regions. These alterations significantly impact biogeochemical processes within stream networks.

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.

Epixylic microbial communities as key regulators of methane emissions from submerged wood in a tropical hydroelectric reservoir

Limnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Tropical hydroelectric reservoirs are recognized hotspots for greenhouse gas emissions, yet the role of submerged forests in these emissions remains poorly understood. In this study, we investigated the contribution of standing dead trees and their associated epixylic biofilms to methane (CH4) and carbon dioxide (CO2) emissions in the ...
