Oxygen minimum zones (OMZs) harbor unique microbial communities that rely on
alternative electron acceptors for respiration. Conditions therein enable an almost complete …

Microbial plankton respiration is the key determinant in the balance between the storage of
organic carbon in the oceans or its conversion to carbon dioxide with accompanying …

The ocean's nitrogen cycle is driven by complex microbial transformations, including
nitrogen fixation, assimilation, nitrification, anammox and denitrification. Dinitrogen is the …

Nitrogen cycling is normally thought to dominate the biogeochemistry and microbial ecology
of oxygen-minimum zones in marine environments. Through a combination of molecular …

We quantified the removal of fixed nitrogen as N2 production by anammox and N2 and N2O
production by denitrification over a distance of 1900 km along the coasts of Chile and Peru …

Nitrous oxide (N2O) is a powerful greenhouse gas and a major cause of stratospheric ozone
depletion, yet its sources and sinks remain poorly quantified in the oceans. We used isotope …

A combination of stable isotopes (15N) and molecular ecological approaches was used to
investigate the vertical distribution and mechanisms of biological N2 production along a …

Oxygen minimum zones (OMZs) have substantial effects on the global ecology and
biogeochemical processes of marine microbes. However, the diversity and activity of OMZ …

Oxygen minimum zones (OMZs) are major sites of fixed nitrogen removal from the open
ocean. However, commonly used gridded data sets such as the World Ocean Atlas (WOA) …

Rapid advances in molecular microbial ecology have yielded an unprecedented amount of
data about the evolutionary relationships and functional traits of microbial communities that …
