The structure and diversity of bacterial communities associated with the oxygen minimum
zone (OMZ) of the eastern tropical South Pacific was studied through phylogenetic analysis …

Anaerobic ammonium oxidation (anammox) has recently been recognized as a pathway for
the removal of fixed N from aquatic ecosystems. However, the quantitative significance of …

The seasonal variations in the advection and mixing of water masses in the northern
Benguela were studied in relation to the oxygen minimum zone over the Namibian shelf …

The biochemical capacity to use water as the source for electrons in photosynthesis evolved
once, in a common ancestor of extant cyanobacteria. The geological record indicates that …

Intact ladderane phospholipids and core lipids were studied in four species of anaerobic
ammonium oxidizing (anammox) bacteria, each representing one of the four known genera …

Population density, nitrate turnover, and oxygen respiration of benthic foraminiferans were
investigated in the oxygen minimum zone (OMZ) off the Chilean coast. Live foraminiferans …

We now have a relatively good idea of how bulk microbial processes shape the cycling of
organic matter and nutrients in the sea. The advent of the molecular biology era in microbial …

Anaerobic ammonium oxidation is a recent addition to the microbial nitrogen cycle, and its
metabolic pathway, including the production and conversion of its intermediate hydrazine, is …

Fixed nitrogen makes up less than 0.1 percent of the nitrogen in the biosphere, and is often
a limiting nutrient for algae that require nitrogen in fixed, or combined, form, typically as …

Bottom-water hypoxia effects on sediment–water interface nitrogen (N) transformations in
Corpus Christi Bay (TX, USA) were examined using continuous-flow intact sediment core …
