Dissolved Organic Matter Impacts Nitrogen Fixation in the Arctic Ocean

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Climate change‐driven sea ice loss, increased primary production, and nitrogen depletion are reshaping biogeochemistry in the Arctic Ocean (AO). These changes potentially increase the importance of nitrogen fixation, the conversion of dinitrogen gas into bioavailable ammonium, carried out by microorganisms called diazotrophs.

Fungal endophyte Phomopsis liquidambari affects nitrogen transformation processes and related microorganisms in the rice rhizosphere

Frontiers in Microbiology, 2015
The endophytic fungus Phomopsis liquidambari performs an important ecosystem service by assisting its host with acquiring soil nitrogen (N), but little is known regarding how this fungus influences soil N nutrient properties and microbial communities. In

The Chaetocerosphere: Chaetoceros Species and Associated Prokaryotes in a Coastal Area

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Chaetoceros species maintain recurrent distinct prokaryotic assemblages in their phycosphere. Alphaproteobacteria, Bacteroidetes and Archaea Thermoplasmata and Marine Group II are the most represented in the phycosphere. Bipartite networks highlight strong links between the diatom and specific prokaryotic taxa, especially the chain‐forming species ...

Multispecies Pasture Reshapes Subsoil Bacterial and Fungal Communities Compared to Ryegrass Monoculture

Grass and Forage Science, Volume 81, Issue 4, October/December 2026.
ABSTRACT Perennial ryegrass (Lolium perenne L.) underpins the pasture‐based dairy industry in Australia, yet its shallow root system limits adaptation to drought conditions. Multispecies pastures, consisting of grasses, legumes and herbs, are increasingly adopted to improve ecosystem resilience, but their interactions with soil microorganisms ...

Responses of Salt Marsh Plant Rhizosphere Diazotroph Assemblages to Drought

, 2018
Drought has many consequences in the tidally dominated Spartina sp. salt marshes of the southeastern US; including major dieback events, changes in sediment chemistry and obvious changes in the landscape.

The sensitivity of marine N2 fixation to dissolved inorganic nitrogen

Frontiers in Microbiology, 2012
The dominant process adding nitrogen (N) to the ocean, di-nitrogen (N2) fixation, is mediated by prokaryotes (diazotrophs) sensitive to a variety of environmental factors.

Microbiome‐mediated plant‐soil feedbacks as a tool for resilient agriculture

iMetaOmics, Volume 3, Issue 3, September 2026.
Translating plant‐soil feedbacks (PSFs) into reliable agricultural management requires shifting from input‐dependent practices toward endogenous, process‐driven crop resilience. To bridge this gap, we propose a predictive framework centered on three strategic interventions: engineering the crop holobiont, diversifying the soil habitat, and deploying ...

Riverine nitrate and nitrification cannot be the only sources for nitrate assimilation in the Amazon River Plume margins

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract The Northern Amazon River Plume plays a crucial role in carbon sequestration and nitrogen cycling. This study quantified NO3− budgets along the plume during a period of high discharge, revealing NO3− uptake rates in excess of inputs from riverine sources and nitrification beyond 5°N.

Planetary structure and drivers of diazotroph communities reveal key reservoirs of nitrogen-fixation potential

Biological nitrogen fixation sustains productivity across Earth's ecosystems, yet the diversity, distribution and ecological drivers of nitrogen-fixing prokaryotes (diazotrophs) remain incompletely resolved.

Giant phytoplankton revealed by in situ imaging

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Deployment of an autonomous Zooglider in the western Mediterranean Sea revealed the presence of long phytoplankton chains attaining maximum lengths of 6.4–10.4 mm suspended in situ. Elongate chains included the diatoms Guinardia, Proboscia, two other diatom morphologies, and solitary filaments of the cyanobacterium Trichodesmium. Most elongate
