The N 2-fixing cyanobacterium Trichodesmium is an important player in the oceanic nitrogen
and carbon cycles. Trichodesmium occurs both as single trichomes and as colonies …

We present the Water Ecosystems Tool (WET)–a new generation of open-source, highly
customizable aquatic ecosystem model. WET is a completely modularized aquatic …

Established as a plant macronutrient, potassium (K) substantially bestows plant growth and
thus, global food production. It is absorbed by plants as potassium cation (K+) from soil …

Nitrogen fixers, or diazotrophs, play a key role in the nitrogen and carbon cycle of the world
oceans. Diazotrophs are capable of utilising atmospheric dinitrogen which is a competitive …

Diatom–diazotroph associations (DDAs) are one of the most important symbiotic dinitrogen
(N2) fixing groups in the oligotrophic ocean. Despite their capability to fix N2, ammonium …

There is considerable debate about the benefits and trade-offs for colony formation in a
major marine nitrogen fixer, Trichodesmium. To quantitatively analyze the trade-offs, we …

Crocosphaera watsonii (hereafter referred to as Crocosphaera) is a key nitrogen (N) fixer in
the ocean, but its ability to consume combined-N sources is still unclear. Using in situ …

Warming oceans may affect how phytoplankton allocate nutrients to essential cellular
processes. Despite the potential impact of such processes on future biogeochemical cycles …

Crocosphaera watsonii is a unicellular N2‐fixing (diazotrophic) cyanobacterium observed in
tropical and subtropical oligotrophic oceans. As a diazotroph, it can be a source of …

Biological N 2 fixation sustains the global inventory of nitrogenous nutrients essential for the
productivity of terrestrial and marine ecosystems. Like most metabolic processes, rates of …
