Surface ocean phosphate is commonly below the standard analytical detection limits,
leading to an incomplete picture of the global variation and biogeochemical role of …

A common assumption of a constant nitrogen-to-phosphorus ratio (N: P) of 16: 1 in marine
particulate organic matter (POM) appears to be invalidated by observations of major spatial …

The factors that control elemental ratios within phytoplankton, like carbon: nitrogen:
phosphorus (C: N: P), are key to biogeochemical cycles. Previous studies have identified …

Iron, phosphate, and nitrate are essential nutrients for phytoplankton growth, and hence,
their supply into the surface ocean controls oceanic primary production. Here we present a …

Diazotrophs or N2-fixers are one of the most ecologically significant groups in marine
ecosystems (pelagic and benthic). Inorganic phosphorus (PO43–) and iron (Fe) can limit the …

Marine cyanobacteria are major contributors to the oceanic carbon sink and are predicted to
increase in numbers in the future warmed ocean. As a result, the influence of marine …

The usefulness of glyphosate [N-(phosphonomethyl) glycine] as a source of nutritive
phosphorus for species of halophilic cyanobacteria has been postulated for years. Our …

This study assessed the species composition, distribution, and functional profiles of
cyanobacteria in Camamu Bay, a tropical oligotrophic estuarine system on the northeast …

Dissolved organic phosphorus (DOP) contains compounds with phosphoester,
phosphoanhydride, and phosphorus–carbon bonds. While DOP holds significant nutritional …

Marine cyanobacteria are key primary producers, contributing significantly to the microbial
food web and biogeochemical cycles by releasing and importing many essential nutrients …
