The continuous increase of the greenhouse gas nitrous oxide (N2O) in the atmosphere due
to increasing anthropogenic nitrogen input in agriculture has become a global concern. In …

A significant proportion of the Earth's surface is desert or in the process of desertification.
The extreme environmental conditions that characterize these areas result in a surface that …

Although the presence of nanoplastics in aquatic and terrestrial ecosystems has received
increasing attention, little is known about its potential effect on ecosystem processes and …

In low-nutrient environments with few vascular plant symbiotic N fixers, biocrusts play an
important role in ecosystem N cycling. A large number of studies across a wide range of …

Reactive nitrogen species have a strong influence on atmospheric chemistry and climate,
tightly coupling the Earth's nitrogen cycle with microbial activity in the biosphere. Their …

Cyanobacteria are ecologically versatile microorganisms inhabiting most environments,
ranging from marine systems to arid deserts. Although they possess several pathways for …

Arid ecosystems cover∼ 40% of the Earth's terrestrial surface and store a high proportion of
the global nitrogen (N) pool. They are low-productivity, low-biomass, and polyextreme …

Biological soil crusts are thin, inconspicuous communities along the soil atmosphere
ecotone that, until recently, were unrecognized by ecologists and even more so by …

Denitrification is one of the major sources of N 2 O in freshwaters. Diverse forms of organic
compounds act as the electron donors for microbial denitrification. However, the influences …

Soils are the largest source of atmospheric nitrous oxide (N2O), a powerful greenhouse gas.
Dry soils rarely harbor anoxic conditions to favor denitrification, the predominant N2O …
