Trait-based approaches to investigate (short-and long-term) phytoplankton dynamics and
community assembly have become increasingly popular in freshwater and marine science …

Hemes are iron containing heterocyclic molecules important in many cellular processes. In
the marine environment, hemes participate as enzymatic cofactors in biogeochemically …

Iron bioavailability limits biological activity in many aquatic and terrestrial environments.
Broad scale genomic meta-analyses indicated that within a single organism, multiple iron …

Siderophores are thought to play an important role in iron cycling in the ocean, but relatively
few marine siderophores have been identified. Sensitive, high throughput methods hold …

Iron (Fe) is a paradox in the modern ocean–it is central to many life-critical enzymes but is
scarce across most surface waters. The high cellular demand and low bioavailability of Fe …

Iron (Fe) is a limiting nutrient in large regions of the ocean, but the strategies of prokaryotes
to cope with this micronutrient are poorly known. Using a gene‐specific approach from …

Oxidative stress and iron limitation represent the grim side of life in an oxygen-rich
atmosphere. The versatile electron transfer shuttle ferredoxin, an iron-sulfur protein, is …

Biological nitrogen fixation (BNF) supplies nutrient-depleted oceanic surface waters with
new biologically available fixed nitrogen. Diazotrophs are the only organisms that can fix …

Biological trace metals are needed by all living organisms in very small quantities. They play
important roles in a variety of key cellular processes, resulting in a varying degree of …

The essential element iron has a low biological availability in the surface ocean where
photosynthetic organisms live. Recent advances in our understanding of iron acquisition …
