Environmental context Organic phosphorus can be one of the major fractions of phosphorus
in many aquatic ecosystems. This paper discusses the distribution, cycling and ecological …

Lipids are structurally diverse biomolecules that serve multiple roles in cells. As such, they
are used as biomarkers in the modern ocean and as paleoproxies to explore the geological …

Phosphorus is an obligate requirement for the growth of all organisms; major biochemical
reservoirs of phosphorus in marine plankton include nucleic acids and phospholipids …

Seeps, spills and other oil pollution introduce hydrocarbons into the ocean. Marine
cyanobacteria also produce hydrocarbons from fatty acids, but little is known about the size …

In marine systems, the availability of inorganic phosphate can limit primary production
leading to bacterial and phytoplankton utilization of the plethora of organic forms available …

Molecular mechanisms of phosphorus (P) limitation are of great interest for understanding
algal production in aquatic ecosystems. Previous studies point to P limitation-induced …

Upon phosphorus (P) deficiency, marine phytoplankton reduce their requirements for P by
replacing membrane phospholipids with alternative non-phosphorus lipids. It was very …

The objectives of the BIOSOPE (BIogeochemistry and Optics SOuth Pacific Experiment)
project was to study, during the austral summer, the biological, biogeochemical and bio …

Fatty acids are generally the most abundant lipid molecules in plankton, and thus play a
central role in the cycling of organic matter in the upper ocean. These fatty acids are …

Phosphorus is a vital nutrient for living organisms and is obtained by bacteria primarily via
phosphate uptake. However, phosphate is often scarcely accessible in nature, and there is …
