Due to their extreme aridity, high rate of UV irradiation and low soil carbon (C) content, the
soils of the Atacama Desert represent one of the world's most hostile environments for …

Abstract The Atacama Desert frequently serves as model system for tracing life under
extremely dry conditions. We hypothesized that traces of life in the Atacama Desert follow …
