Phytoplankton and Temperature Control Seasonal Dynamics of Greenhouse Gases in a Large River
Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.Abstract Rivers are a dynamic source of greenhouse gases (GHGs), yet the temporal variability and controlling mechanisms of their CO2:CH4:N2O ratios remain poorly constrained. We monitored the three GHGs in the German river Elbe over 5 years at two sites to identify seasonal controls as well as travel time related and site‐specific mechanisms driving ...

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‐

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.

In‐Lake GHG Production Constrained by Lake DOM Mass Balance in a Boreal Catchment
Water Resources Research, Volume 62, Issue 5, May 2026.Abstract The processing of organic carbon in surface waters represents a critical component of the carbon (C) cycle in boreal landscapes and is closely linked to greenhouse gas (GHG) emissions, primarily carbon dioxide (CO2) and methane (CH4). Utilizing a unique data set with dense monitoring of dissolved organic carbon (DOC), dissolved CO2, and CH4 at

Water Resources Research, Volume 62, Issue 5, May 2026.Abstract Trace organic compounds (TrOCs) in lotic systems pose risks for ecosystem and human health. TrOCs can enter groundwater along losing river sections, yet little is known about the spatial extent of infiltration zones and the biogeochemical factors controlling the spatial variability of TrOC reactivity and removal, particularly along river‐to ...

A new global gas hydrate budget based on numerical reaction-transport modeling and a novel parameterization of Holocene and Quaternary sedimentation [PDF]
, 2011 This study provides new estimates for the global methane hydrate inventory based on reaction-transport modeling [1]. A multi-1D model for POC degradation, gas hydrate formation and dissolution is presented.

The unique biochemistry of methanogenesis
, 2002 Methanogenic archaea have an unusual type of metabolism because they use H2 + CO2, formate, methylated C1 compounds, or acetate as energy and carbon sources for growth. The methanogens produce methane as the major end product of their metabolism in a unique energy-generating process.

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability
Functional Ecology, Volume 40, Issue 5, Page 1251-1269, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

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 ...
