For all living organisms, nitrogen is an essential element, while being the most limiting in
ecosystems and for crop production. Despite the significant contribution of synthetic …

Nitrogen (N) is used in many of life's fundamental biomolecules, and it is also a participant in
environmental redox chemistry. Biogeochemical processes control the amount and form of N …

Aquatic Photosynthesis is a comprehensive guide to understanding the evolution and
ecology of photosynthesis in aquatic environments. This second edition, thoroughly revised …

Virtually all nonequilibrium electron transfers on Earth are driven by a set of nanobiological
machines composed largely of multimeric protein complexes associated with a small …

Heterocyst differentiation that occurs in some filamentous cyanobacteria, such as Anabaena
sp. PCC 7120, provides a unique model for prokaryotic developmental biology. Heterocyst …

A single-source reference on the biology of algae, the third edition of Algae: Anatomy,
Biochemistry, and Biotechnology examines the most important taxa and structures for …

In recent years, our understanding of biological nitrogen fixation has been bolstered by a
diverse array of scientific techniques. Still, the origin and extant distribution of nitrogen …

Biological N2 fixation is an important part of the marine nitrogen cycle as it provides a source
of new nitrogen that can support biological carbon export and sequestration. Research in …

Discrepancies between estimates of oceanic N 2 fixation and nitrogen (N) losses through
denitrification have focused research on identifying N 2-fixing cyanobacteria and quantifying …

In both marine and freshwaters, the concentration of dissolved organic nitrogen (DON)
frequently exceeds that of dissolved inorganic nitrogen (DIN), including ammonium, nitrate …
