Microbialites provide geological evidence of one of Earth's oldest ecosystems, potentially
recording long-standing interactions between coevolving life and the environment. Here, we …

For decades, the search for potential signs of Martian life has attracted strong international
interest and has led to significant planning and scientific implementation. Clearly, in order to …

Microbes are crucial in removing various xenobiotics, including pesticides, from the
environment, specifically by mineralizing these hazardous pollutants. However, the specific …

Abstract The Salar de Llamara, Atacama Desert is host to saline lakes known as Puquios,
which are possible analogs for lakes on early Earth or Mars. Here we examine associations …

A set of 55 surface samples from Atacama Desert gypsisols was collected along four altitude
transects and analyzed for∆ 17 O SO4, δ 18 O SO4, δ 34 S SO4, and 87 Sr/86 Sr in order to …

Gypsum is an important environmental archive in hyperarid settings, but its application in
earth sciences has been hampered by the limited availability of suitable dating methods …

Actinobacterial community is a conspicuous part of aquatic ecosystems and displays an
important role in the case of biogeochemical cycle, but little is known about the seasonal …

Despite the harsh environmental conditions in the world's oldest and driest desert, some salt
flat or 'salar'environments in the Atacama Desert host standing bodies of water known as …

The Puquios of the Salar de Llamara in the Atacama Desert, northern Chile, is a system of
small lakes that is characterized by evaporitic mineral deposition and that commonly hosts …

Gypsum twins are frequently observed in nature, triggered by a wide array of impurities that
are present in their depositional environments and that may exert a critical role in the …
