The purpose of this review is to better understand the full life cycle and influence of ammonia
from an aquatic biology perspective. While ammonia has toxic properties in water and air, it …

In this review we explore the biotic transformations of nitrogenous compounds that occur
during denitrification, and the factors that influence denitrifier populations and enzyme …

Soils represent the largest carbon reservoir within terrestrial ecosystems. The mechanisms
controlling the amount of carbon stored and its feedback to the climate system, however …

Stream Ecology: Structure and Function of Running Waters is designed to serve as a
textbook for advanced undergraduate and graduate students, and as a reference source for …

Production and consumption processes in soils contribute to the global cycles of many trace
gases (CH4, CO, OCS, H2, N2O, and NO) that are relevant for atmospheric chemistry and …

The microplastics in nature water are important for the environmental fate of nitrous oxide (N
2 O). This study investigated the influence and microbial mechanism of microplastic …

Lowland river–floodplain systems are characterized by a high degree of variability in both
the frequency and period of inundation of various parts of the floodplain. Such variation …

The regulatory effect of salinity on nitrogen dynamics in estuarine sediments was
investigated in the Randers Fjord estuary, Denmark, using sediment slurries and intact …

Fixed nitrogen limits primary productivity in many parts of the global ocean, and it
consequently plays a role in controlling the carbon dioxide content of the atmosphere. The …

We measured rates of N2 production through anaerobic NH4+ oxidation with
NO2−(anammox) and denitrification in permanently cold (from− 1.7° C to 4° C) sediments off …
