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

Frontiers in Microbiology, 2022 Recent studies have indicated that heterotrophic diazotrophs are highly diverse and fix N2 in aquatic environments with potentially adverse conditions for diazotrophy, such as oxic and rich in total nitrogen.

Anthropogenic impact on diazotrophic diversity in the mangrove rhizosphere revealed by nifH pyrosequencing [PDF]
Frontiers in Microbiology, 2015 Diazotrophs in the mangrove rhizosphere play a major role in providing new nitrogen to the mangrove ecosystem and their composition and activity are strongly influenced by anthropogenic activity and ecological conditions.

Enhancing biological nitrogen fixation in rice paddy ecosystems: challenges, opportunities, and sustainable strategies [PDF]
Frontiers in MicrobiologySynthetic nitrogen (N) fertilizers have substantially increased rice (Oryza sativa) yields but at the expense of low N use efficiency, significant environmental losses, and deterioration of soil health.

Diazotrophs and N2-Fixation Associated With Particles in Coastal Estuarine Waters
Frontiers in Microbiology, 2018 Putative heterotrophic bacteria carrying out N2-fixation, so-called non-cyanobacterial diazotrophs (NCDs), are widely distributed in marine waters, but details of how the O2-inhibited N2-fixation process is promoted in the oxic water column remains ...

nifH gene expression and diversity in geothermal springs of Tengchong, China
Frontiers in Microbiology, 2022 Terrestrial hot springs have been suggested to harbor diverse diazotrophic lineages by using DNA-based nifH gene phylogenetic analysis. However, only a small amount of diazotrophs were ever confirmed to perform nitrogen fixation.

Temporal dynamics of total and active root-associated diazotrophic communities in field-grown rice
Frontiers in Microbiology, 2022 Plant-associated nitrogen-fixing microorganisms (diazotrophs) are essential to host nutrient acquisition, productivity and health, but how host growth affects the succession characteristics of crop diazotrophic communities is still poorly understood ...

Frontiers in Microbiology, 2022 The excessive usage of nitrogen (N) fertilizers can accelerate the tendency of global climate change. Biological N fixation by diazotrophs contributes substantially to N input and is a viable solution to sustainable agriculture via reducing inorganic N ...

Drivers and uncertainties of future global marine primary production in marine ecosystem models [PDF]
, 2015 Past model studies have projected a global decrease in marine net primary production (NPP) over the 21st century, but these studies focused on the multi-model mean rather than on the large inter-model differences. Here, we analyze model-simulated changes

Can Top-Down Controls Expand the Ecological Niche of Marine N2 Fixers?
Frontiers in Microbiology, 2021 The ability of marine diazotrophs to fix dinitrogen gas (N2) is one of the most influential yet enigmatic processes in the ocean. With their activity diazotrophs support biological production by fixing about 100–200 Tg N/year and turning otherwise ...
