Microbial activity is a fundamental component of oceanic nutrient cycles. Photosynthetic
microbes, collectively termed phytoplankton, are responsible for the vast majority of primary …

The marine nitrogen (N) cycle controls the productivity of the oceans. This cycle is driven by
complex biogeochemical transformations, including nitrogen fixation, denitrification, and …

A global three‐dimensional marine ecosystem model with several key phytoplankton
functional groups, multiple limiting nutrients, explicit iron cycling, and a mineral …

The factors that control the growth and nitrogen fixation rates of marine diazotrophs such as
Trichodesmium have been intensively studied because of the role that these processes …

The new genus name Dolichospermum, for most of the planktonic former members of the
genus Anabaena, is one of the most ubiquitous bloom-forming cyanobacterial genera. Its …

We discuss the concept of colimitation of primary productivity in aquatic environments, with
an emphasis on reconciling this concept with recent advances in marine bioinorganic …

Methylphosphonate is an organic phosphorus compound used by microorganisms when
phosphate, a key nutrient limiting growth in most marine surface waters, becomes …

The macronutrient phosphorus is critical to the physiological ecology of eukaryotic
microalgae and cyanobacteria. What are the forms of phosphorus produced and used by …

Phosphorus is an essential macronutrient for all marine microorganisms. Dissolved organic
phosphorus (DOP) is an integral, dynamic part of the marine organic matter pool and of the …

Inorganic phosphorus (SRP) concentrations in the subtropical North Atlantic are some of the
lowest in the global ocean and have been hypothesized to constrain primary production …
