The stability and function of a microbial community depends on nutritional interactions
among community members such as the cross-feeding of essential small molecules …

The soluble B vitamins (B1, B7, and B12) have long been recognized as playing a central
metabolic role in marine phytoplankton and bacteria; however, the importance of these …

Southern Ocean primary productivity plays a key role in global ocean biogeochemistry and
climate. At the Southern Ocean sea ice edge in coastal McMurdo Sound, we observed …

Stoffhaushalt ist die Summe des Stoff-und Energieumsatzes in einem Ökosystem. Die
Untersuchung des Stoffhaushaltes eines Gewässers geht von der Feststellung der gelösten …

The growth dynamics of populations of interacting species in the aquatic environment is of
great importance, both for understanding natural ecosystems and in efforts to cultivate these …

Cobalamin (vitamin B12) is a complex metabolite and essential cofactor required by many
branches of life, including most eukaryotic phytoplankton. Algae and other cobalamin …

We here review the ecological role of essential nutritional biomolecules [fatty acids (FA),
amino acids (AA), sterols, vitamins] in aquatic and terrestrial food webs, encompassing the …

B vitamins are some of the most commonly required biochemical cofactors in living systems.
Therefore, cellular metabolism of marine vitamin-requiring (auxotrophic) phytoplankton and …

A breeding colony of notothenioid icefish (Neopagetopsis ionah, Nybelin 1947) of globally
unprecedented extent has been discovered in the southern Weddell Sea, Antarctica. The …

Trace metals shape both the biogeochemical functioning and biological structure of oceanic
provinces. Trace metal biogeochemistry has primarily focused on modes of external supply …
