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

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

Seasonal and spatial patterns in diazotroph community composition at Station ALOHA
Frontiers in Marine Science, 2023 Dinitrogen (N2) fixation is carried out by specialized microbes, called diazotrophs, and is a major source of nitrogen supporting primary production in oligotrophic oceans.

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 ...

Soil diazotrophs sustain nitrogen fixation under high nitrogen enrichment via adjustment of community composition [PDF]
mSystemsBiological nitrogen (N) fixation, an important pathway of N, inputs from the atmosphere to Earth’s ecosystems, is well demonstrated to decline under N input.

Impacts of Managed Vegetation Restoration on Arbuscular Mycorrhizal Fungi and Diazotrophs in Karst Ecosystems [PDF]
Journal of FungiThe crucial functional arbuscular mycorrhizal fungi (AMF) and diazotrophs play pivotal roles in nutrient cycling during vegetation restoration. However, the impact of managed vegetation restoration strategies on AMF and diazotroph communities remains ...

Chemosynthetic alphaproteobacterial diazotrophs reside in deep-sea cold-seep bottom waters [PDF]
mSystemsNitrogen (N)-fixing organisms, also known as diazotrophs, play a crucial role in N-limited ecosystems by controlling the production of bioavailable N. The carbon-dominated cold-seep ecosystems are inherently N-limited, making them hotspots of N fixation.
