Diversity and Activity of Diazotrophs in Great Barrier Reef Surface Waters

Frontiers in Microbiology, 2017
Discrepancies between bioavailable nitrogen (N) concentrations and phytoplankton growth rates in the oligotrophic waters of the Great Barrier Reef (GBR) suggest that undetermined N sources must play a significant role in supporting primary productivity ...

Projected AMOC Weakening Controls Future Diatom Decline in the Subpolar North Atlantic Ocean

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Climate models consistently project a decline in diatom net primary production (NPP) under high‐emission scenarios in the highly productive subpolar North Atlantic. However, the magnitude of this decline remains highly uncertain and varies substantially across models, limiting our ability to anticipate its ecological and biogeochemical ...

Cretaceous moss–cyanobacteria association reveals trophic interactions in polar forests of Antarctica

New Phytologist, Volume 251, Issue 6, Page 3627-3639, September 2026.
Kimmerera cyanifera gen. et sp. nov. with associated cyanobacteria, holotype UWBM 116051. Summary Through symbiotic associations with microbes, mosses play many important ecological roles in terrestrial ecosystems, such as facilitating trophic interactions and nitrogen cycling.

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 plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

iMeta, Volume 5, Issue 4, August 2026.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

Phosphate modulates elemental and macromolecular composition of unicellular nitrogen‐fixing cyanobacteria

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract The C : N : P of nitrogen‐fixing cyanobacteria regulates phosphate‐limited nitrogen fixation in the ocean yet the causes and range in variation C : N : P is not well constrained. Here we quantify the C : N : P and underlying macromolecular composition of Crocosphaera.

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.

Benguela Upwelling Filaments Are a Significant Pathway of New Nutrients to the South Atlantic Subtropical Gyre

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract In the transition zones between eastern boundary upwelling regions and subtropical gyres, upwelling and offshore moving filaments generated by frontal instabilities play an important role in the gyre‐ward transport of new nutrients and phytoplankton biomass. However, quantification of such transport using field data remains sparse.

Table_1_Protistal Grazers Increase Grazing on Unicellular Cyanobacteria Diazotroph at Night.pdf

, 2020
In this study, we have for the first time analyzed diel microzooplankton grazing selectivity on unicellular cyanobacterial diazotroph (i.e., Crocosphaera watsonii WH8501) and non-diazotrophic unicellular microalga (i.e., Chlorella autotrophica).

The ASTE‐BGC Data‐Assimilative Regional Ocean Biogeochemical Model

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 8, August 2026.
Abstract We present a data‐assimilative regional ocean biogeochemical model, ASTE‐BGC, which simulates the physical and biogeochemical state of the North Atlantic Ocean from 2002 to 2017. Model physics are provided by a physical state estimate (ASTE), which assimilates O(109) in situ and satellite‐based observations over the model domain and time ...
