Anthropogenic climate change may reduce global diazotroph diversity [PDF]
Nature CommunicationsClimate change impacts microbial community structure and function, thus altering biogeochemical cycles. Biological nitrogen fixation by diazotrophs is involved in maintaining the balance of the global nitrogen cycle, but the global biogeographic patterns

Light-driven integration of diazotroph-derived nitrogen in euphotic nitrogen cycle [PDF]
Nature CommunicationsThe bioavailable nitrogen fixed by diazotrophs is critical for sustaining productivity in the oligotrophic ocean. Despite this, understanding how diazotroph-derived nitrogen integrates into the nitrogen cycle within the euphotic zone remains unknown ...

Highly Variable and Non-complex Diazotroph Communities in Corals From Ambient and High CO2 Environments [PDF]
Frontiers in Marine Science, 2021 The ecological success of corals depends on their association with microalgae and a diverse bacterial assemblage. Ocean acidification (OA), among other stressors, threatens to impair host-microbial metabolic interactions that underlie coral holobiont ...

Cyanobacterial Diazotroph Distributions in the Western South Atlantic [PDF]
Frontiers in Marine Science, 2022 Inputs of new nitrogen by cyanobacterial diazotrophs are critical to ocean ecosystem structure and function. Relative to other ocean regions, there is a lack of data on the distribution of these microbes in the western South Atlantic. Here, the abundance

Excess labile carbon promotes diazotroph abundance in heat-stressed octocorals
Royal Society Open Science, 2023 Nitrogen limitation is the foundation of stable coral-algal symbioses. Diazotrophs, prokaryotes capable of fixing N2 into ammonia, support the productivity of corals in oligotrophic waters, but could contribute to the destabilization of holobiont ...

Overlooked and widespread pennate diatom-diazotroph symbioses in the sea [PDF]
, 2022 \ua9 2022, The Author(s). Persistent nitrogen depletion in sunlit open ocean waters provides a favorable ecological niche for nitrogen-fixing (diazotrophic) cyanobacteria, some of which associate symbiotically with eukaryotic algae.
