Biological nitrogen (N 2) fixation is critical in global biogeochemical cycles and in sustaining
the productivity of the oceans. There remain many unanswered questions, unresolved …

Marine diazotrophs convert dinitrogen (N 2) gas into bioavailable nitrogen (N), supporting
life in the global ocean. In 2012, the first version of the global oceanic diazotroph database …

The distribution of total soil nitrogen (TSN) and total soil phosphorus (TSP) plays a pivotal
role in sha** soil quality, fertility, agricultural practices, and environmental balance …

Dinitrogen (N2) fixation provides the major source of reactive nitrogen in the open ocean,
sustaining biological productivity. The Indian Ocean (IO) covers 22% of the ocean surface …

The high diversity and global distribution of heterotrophic bacterial diazotrophs (HBDs) in
the ocean has recently become apparent. However, understanding the role these largely …

Biological nitrogen fixation plays a critical role in maintaining primary production, particularly
in systematic nitrogen deficiency. However, little is known about the dynamics within …

Dinitrogen (N2) fixation is the major source of reactive nitrogen in the ocean and has been
considered to occur specifically in low-latitude oligotrophic oceans. Recent studies have …

The factors that govern the geographical distribution of nitrogen fixation are fundamental to
providing accurate nitrogen budgets in aquatic environments. Model-based insights have …

N2-fixing microorganisms (diazotrophs) sustain life on our planet by providing biologically
available nitrogen to plants. In the oceans, cyanobacterial diazotrophs, mostly prevalent in …

Diazotrophs provide a significant reactive nitrogen source in the ocean. Increased warming
and stratification may decrease nutrient availability in the future, forcing microbial …
