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 …

Biodiversity of phytoplankton is important for ecosystem stability and marine
biogeochemistry. However, the large-scale patterns of diversity are not well understood and …

Bacteria and archaea are central to the production, consumption, and remineralization of
dissolved and particulate organic matter and contribute critically to carbon delivery, nutrient …

The Thaumarchaeota is a diverse archaeal phylum comprising numerous lineages that play
key roles in global biogeochemical cycling, particularly in the ocean. To date, all …

Light fuels photosynthesis and organic matter production by primary producers in the sunlit
ocean. The quantity and quality of the organic matter produced influence community …

Phytoplankton transform inorganic carbon into thousands of biomolecules that represent an
important pool of fixed carbon, nitrogen, and sulfur in the surface ocean. Metabolite …

Symbiosis between a marine alga and a N2-fixing cyanobacterium (Cyanobacterium UCYN-
A) is geographically widespread in the oceans and is important in the marine N cycle. UCYN …

Marine diazotrophs convert dinitrogen (N 2) in seawater into bioavailable nitrogen (N),
contributing approximately half of the external input of bioavailable N to the global ocean. A …

Crocosphaera is a major dinitrogen (N2)-fixing microorganism, providing bioavailable
nitrogen (N) to marine ecosystems. The N2-fixing enzyme nitrogenase is deactivated by …

Heterotrophic prokaryotic production (BP) was studied in the western tropical South Pacific
(WTSP) using the leucine technique, revealing spatial and temporal variability within the …
