Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.Abstract Estuaries are critical for land‐ocean carbon exchange, but coupling mechanisms between air–sea CO2 fluxes (FCO2) and phytoplankton gross primary productivity (GPP) remain poorly understood. This study used high‐frequency underway monitoring in the Lingdingyang Estuary to resolve spatiotemporal interplays between FCO2 and GPP.

Carbon fixation from mineral carbonates
Nature Communications, 2017 Evidence showing that carbonates can directly supply CO2 for autotrophy is lacking. Here, using stable isotope analyses and NanoSIMS imaging, the authors show that a model euendolith, Mastigocoleus testarum strain BC008, derives the majority of its ...

Metagenomic insights into S(0) precipitation in a terrestrial subsurface lithoautotrophic ecosystem
Frontiers in Microbiology, 2015 The Frasassi and Acquasanta Terme cave systems in Italy host isolated lithoautotrophic ecosystems characterized by sulfur-oxidizing biofilms with up to 50% S(0) by mass.

On modeling chronic detachment of periphyton in artificial rough, open channel flow [PDF]
, 2012 Periphyton communities, which are native to river beds, serve as a functional indicator of river health but remain one of the least-studied communities despite the significant increase in the examination of aquatic microbial communities in recent years ...

Cross‐Feeding of Carbon and Nitrogen Between Aquificales and Thermus in Hot Springs
Environmental Microbiology, Volume 28, Issue 1, January 2026.Pampinifervens and Thermus populations are co‐distributed in hot springs in Yellowstone and Iceland. Genome reconstruction suggests Pampinifervens Flu05 cross feeds Thermus organic carbon and nitrogen, a phenomenon that was verified via co‐culture studies.

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.ABSTRACT The inclusion of functional traits of protists in environmental sequencing surveys, in addition to the traditional taxonomic framework, is essential for a better understanding of their roles and impacts on ecosystem processes. We provide a database of functional traits for a widespread and important clade of protists—the Amoebozoa—based on ...

The effects of intense fire on headwater streams of the Colville National Forest, WA [PDF]
, 2006 Thesis (M.S.) University of Alaska Fairbanks, 2006Forest fires play an important role in shaping ecosystems, and there has been growing concern on the effects of high intensity fires on forest and aquatic ecosystems.

The Plant Journal, Volume 125, Issue 2, January 2026.SUMMARY The regulation of photosynthetic electron transport during photomixotrophic growth in cyanobacteria remains incompletely understood. In this study, we characterized four wild‐type strains (WT 1–4) of Synechocystis sp. PCC 6803 and observed distinct strain‐specific differences in photosystem II (PSII) function under photomixotrophic conditions ...

A Tale of Two Sylamores: Understanding Relationships Among Land Use, Nutrients, and Aquatic Communities Across a Subsidy-Stress Gradient [PDF]
, 2019 Agricultural land use is known to degrade aquatic systems with high inputs of nutrients, sediments, and pesticides. Increased nutrients can lead to increased algal growth and thus possible hypoxic conditions in slow moving water, while increased sediment
