Comparison of Diazotrophic Composition and Distribution in the South China Sea and the Western Pacific Ocean

open access: yesBiology, 2021
The variation of diazotrophs has been elusive in multiple SCS and WPO regions due to insufficient data. Therefore, the dynamics of diazotrophic composition and distribution were investigated in this study, based on high-throughput sequencing and ...

Diazotroph community succession during the VAHINE mesocosm experiment (New Caledonia lagoon) [PDF]

open access: yesBiogeosciences, 2015
The VAHINE mesocosm experiment, conducted in the low-nutrient low-chlorophyll waters of the Noumea lagoon (coastal New Caledonia) was designed to trace the incorporation of nitrogen (N) fixed by diazotrophs into the food web, using large volume (50 m3 ...

Unstable Relationship Between Braarudosphaera bigelowii (= Chrysochromulina parkeae) and Its Nitrogen-Fixing Endosymbiont

open access: yesFrontiers in Plant Science, 2021
Marine phytoplankton are major primary producers, and their growth is primarily limited by nitrogen in the oligotrophic ocean environment. The haptophyte Braarudosphaera bigelowii possesses a cyanobacterial endosymbiont (UCYN-A), which plays a major role

Salinity as a key control on the diazotrophic community composition in the southern Baltic Sea [PDF]

open access: yesOcean Science, 2022
Over the next decade, the Baltic Sea is predicted to undergo severe changes including decreased salinity due to altered precipitation related to climate changes.

Seasonal Shifts in Diazotrophs Players: Patterns Observed Over a Two-Year Time Series in the New Caledonian Lagoon (Western Tropical South Pacific Ocean)

open access: yesFrontiers in Marine Science, 2020
Coastal and open ocean regions of the Western Tropical South Pacific ocean have been identified as a hotspot of N2 fixation. However, the environmental factors driving the temporal variability of abundance, composition, and activity of diazotrophs are ...

Contribution and pathways of diazotroph-derived nitrogen to zooplankton during the VAHINE mesocosm experiment in the oligotrophic New Caledonia lagoon [PDF]

open access: yesBiogeosciences, 2016
In oligotrophic tropical and subtropical oceans, where strong stratification can limit the replenishment of surface nitrate, dinitrogen (N2) fixation by diazotrophs can represent a significant source of nitrogen (N) for primary production.

Genetic diversity of the unicellular nitrogen‐fixing cyanobacteria UCYN ‐ A and its prymnesiophyte host [PDF]

open access: yesEnvironmental Microbiology, 2014
Summary Symbiotic interactions between nitrogen‐fixing prokaryotes and photosynthetic eukaryotes are an integral part of biological nitrogen fixation at a global scale. One of these partnerships involves the cyanobacterium UCYN ‐ A ...

Response of the unicellular diazotrophic cyanobacterium Crocosphaera watsonii to iron limitation. [PDF]

open access: yesPLoS ONE, 2014
Iron (Fe) is widely suspected as a key controlling factor of N2 fixation due to the high Fe content of nitrogenase and photosynthetic enzymes complex, and to its low concentrations in oceanic surface seawaters.

The response of diazotrophs to nutrient amendment in the South China Sea and western North Pacific [PDF]

open access: yesBiogeosciences, 2022
The availability of iron (Fe) and phosphorus (P) has been shown to be a key factor regulating rates of nitrogen fixation in the western subtropical Pacific.
