Microbial communities inhabiting “subterranean estuaries” along the subsurface freshwater–
saltwater continuum determine the fate of nitrogen discharged to coastal waters. Little is …

Processing of organic matter in tidal estuaries modifies its transfer from the river to the sea.
We examined the distribution and the elemental and isotopic composition of organic matter …

Nitrification is the process whereby ammonium (NH4 þ) is oxidized to nitrite (NO2 À) and
then to nitrate (NO3 À). It thus links the most oxidized and most reduced components of the …

The motivation to develop microgrids, as a particular form of active networks is explained
and presented as an effective solution for the control of grids with high levels of distibuted …

The diversity and spatio-temporal distribution of ammonia-oxidizing Archaea (AOA) and
Bacteria (AOB) were investigated along a salinity gradient in sediments of the …

Marine sponges represent one of the few eukaryotic groups that frequently harbour
symbiotic members of the Thaumarchaeota, which are important chemoautotrophic …

Understanding rates of nitrogen cycling in estuaries is crucial for understanding their
productivity and resilience to eutrophication. Nitrification, the microbial oxidation of ammonia …

In this study, the vertical distribution of mercury (Hg) in estuarine and marine sediment
porewaters and solid phases was assessed by conventional and passive sampling …

In recirculating aquaculture systems (RAS), the crucial step of eliminating toxic N
compounds like ammonia and nitrite is mediated via nitrifying microorganisms and takes …

Nitrification is a series of processes that oxidizes ammonia to nitrate, which contributes to
hypoxia development in coastal oceans, especially in eutrophicated regions. The nitrification …
