Heterotrophic Nitrogen Fixation at the Hyper-Eutrophic Qishon River and Estuary System
Frontiers in Microbiology, 2020 Planktonic heterotrophic diazotrophs (N2-fixers) are widely distributed in marine and freshwater systems, yet limited information is available on their activity, especially in environments with adverse conditions for diazotrophy (e.g., N-rich and ...

Evidence For The Functional Significance Of Microbial Diversity Among Free-Living Diazotrophs In Soils Of A Long Term Agricultural Site [PDF]
, 2011 Diazotrophs, microorganisms that fix atmospheric N2 into NH4, fill a crucial role in the nitrogen cycle providing the dominant natural source of fixed N in the biosphere.

Heat stress reduces the contribution of diazotrophs to coral holobiont nitrogen cycling [PDF]
, 2022 Efficient nutrient cycling in the coral-algal symbiosis requires constant but limited nitrogen availability. Coral-associated diazotrophs, i.e., prokaryotes capable of fixing dinitrogen, may thus support productivity in a stable coral-algal symbiosis but

Frontiers in Physiology, 2020 Coral reef ecosystems cannot operate normally without an effective nitrogen cycle. For oligotrophic coral reef areas, coral-associated diazotrophs are indispensable participants in the nitrogen cycle.

Responses of soil diazotrophs to legume species and density in a karst grassland, southwest China
, 2020 Diazotrophs have potential for fixing atmospheric nitrogen (N) in terrestrial ecosystems. The effects of legumes on free-living N-fixing diazotrophs in the karst grassland were determined to provide a basis for ecosystem restoration.

The Unique Biogeochemical Signature of the Marine Diazotroph Trichodesmium [PDF]
Frontiers in Microbiology, 2012 The elemental composition of phytoplankton can depart from canonical Redfield values under conditions of nutrient limitation or production (e.g., N fixation). Similarly, the trace metal metallome of phytoplankton may be expected to vary as a function of both ambient nutrient concentrations and the biochemical processes of the cell.
