Natural processes and human activities play a crucial role in changing the nitrogen cycle
and increasing nitrous oxide (N 2 O) emissions, which are accelerating at an unprecedented …

Composite pollutants are prevalent in wastewater, whereas, the simultaneous
accomplishment of efficient nitrogen removal and resources recovery remains a challenge …

Nitrous oxide (N 2 O) is an important ozone-depleting greenhouse gas produced and
consumed by microbially mediated nitrification and denitrification pathways. Estuaries are …

Effects of nitrogen (N) deposition on microbially-driven processes in oligotrophic freshwater
ecosystems are poorly understood. We quantified guilds in the main N-transformation …

Who's cooking, who's cleaning, and who's got the remote control within the waters
blanketing Earth? Anatomically tiny, numerically dominant microbes are the crucial …

The reservoir size and pathway rates of the nitrogen (N) cycle have been deeply modified by
the human enhancement of N fixation, atmospheric emissions, and climate warming …

Abstract The Bohai Sea has recently suffered several seasonal oxygen-deficiency, even
hypoxia events during the summer. To better understand effects of dissolved oxygen (DO) …

In recent years, the coupling of Fe (II) oxidation and denitrification has attracted more
attention. However, the activity of autotrophic Fe (II)-oxidizing denitrifiers in freshwater …

During the last decades, atmospheric nitrogen loading in mountain ranges of the Northern
Hemisphere has increased substantially, resulting in high nitrate concentrations in many …

This chapter addresses the question of why the high mountain lakes of Sierra Nevada
(Spain) areunique remote sensorsof global change. The answers arise from a set of peculiar …
