The ocean enabled the diversification of life on Earth by adding O2 to the atmosphere, yet
marine species remain most subject to O2 limitation. Human industrialization is intensifying …

Viruses play an important role in the ecology and biogeochemistry of marine ecosystems.
Beyond mortality and gene transfer, viruses can reprogram microbial metabolism during …

Microbial activity mediates the fluxes of greenhouse gases. However, in the global models of
the marine and terrestrial biospheres used for climate change projections, typically only …

Denitrification, as the main nitrogen (N) removal process in farmland drainage ditches in
coastal areas, is significantly affected by saline-alkali conditions. To elucidate the effects of …

Nitrite is a pivotal component of the marine nitrogen cycle. The fate of nitrite determines the
loss or retention of fixed nitrogen, an essential nutrient for all organisms. Loss occurs via …

Microbial communities in marine oxygen deficient zones (ODZs) are responsible for up to
half of marine N loss through conversion of nutrients to N2O and N2. This N loss is …

Mechanistic description of the transition from aerobic to anaerobic metabolism is necessary
for diagnostic and predictive modeling of fixed nitrogen loss in anoxic marine zones (AMZs) …

Oxygen deficient zones (ODZs) in the tropical ocean exert a profound influence on global
biogeochemical cycles, but the factors that regulate their long‐term structure and sensitivity …

Fixed nitrogen limits primary productivity in most areas of the surface ocean. Nitrite oxidation
is the main source of nitrate, the most abundant form of inorganic fixed nitrogen. Even …

Abstract The Yangtze River, which is the largest in Euro-Asian, receives tremendous
anthropogenic nitrogen input and is typically characterized by severe eutrophication and …
