Constraining uncertainties of diazotroph biogeography from nifH gene abundance [PDF]
Limnology and Oceanography, 2022 Marine diazotrophs fix dinitrogen gas into bioavailable nitrogen that drives the ocean nitrogen cycle; yet, efforts to infer global diazotroph distributions have been limited by a sparsity of observations.

Nitrogen fixation and nifH diversity in human gut microbiota [PDF]
Scientific Reports, 2016 It has been hypothesized that nitrogen fixation occurs in the human gut. However, whether the gut microbiota truly has this potential remains unclear. We investigated the nitrogen-fixing activity and diversity of the nitrogenase reductase (NifH) genes in

Characterization of a nifH-Harboring Bacterial Community in the Soil-Limited Gotjawal Forest
Frontiers in Microbiology, 2019 Using a high-throughput metagenomic approach, we evaluated nifH-harboring bacterial communities and their assembly in the Gotjawal forest, which was naturally formed on basalt rocks with thin layer of soil.

Frontiers in Microbiology, 2012 The Tropical North Atlantic (TNAtl) plays a critical role in the marine nitrogen cycle, as it supports high rates of biological nitrogen (N2) fixation, yet it is unclear whether this process is limited by the availability of iron (Fe), phosphate (P) or ...

Climate Change Impacts the Structure and Nitrogen-Fixing Activities of Subarctic Feather Moss Microbiomes Across a Precipitation Gradient. [PDF]
Glob Chang BiolAssociations between mosses and cyanobacteria are crucial sources of new nitrogen in arctic and subarctic ecosystems. The physiology of both mosses and cyanobacteria is strongly influenced by environmental factors such as temperature and moisture, which directly affect N2 fixation rates.

Biological nitrogen fixation and nifH gene abundance in deadwood of 13 different tree species
Biogeochemistry, 2022 Deadwood is an extremely nitrogen (N) poor plant litter whose decomposition may rely on external N sources. Biological N2 fixation (BNF) by free-living diazotrophs, encoded with the nifH gene, is a potential pathway of N acquisition in deadwood.
