Long-term carbon and nitrogen dynamics at SPRUCE revealed through stable isotopes in peat profiles [PDF]

, 2017
Peatlands encode information about past vegetation dynamics, climate, and microbial processes. Here, we used δ15N and δ13C patterns from 16 peat profiles to deduce how the biogeochemistry of the Marcell S1 forested bog in northern Minnesota responded to ...

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.

Evening Methane Emission Pulses from a Boreal Wetland Correspond to Convective Mixing in Hollows [PDF]

, 2013
Spatial and temporal heterogeneity of methane flux from boreal wetlands makes prediction and up-scaling challenging, both within and among wetland systems.

Eutrophication and ice phenology influence methane storage in north temperate lakes

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Among lakes, eutrophication is positively related to methane emissions, but various processes can alter the seasonal conversion of primary production into stored methane. We used a series of whole‐lake enrichment and shading experiments across three years with varying ice phenology to assess how eutrophication and ice cover affect within‐year ...

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.

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‐

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.
