Living at the Frontiers of Life: Extremophiles in Chile and Their Potential for Bioremediation

Frontiers in Microbiology, 2018
Extremophiles are organisms capable of adjust, survive or thrive in hostile habitats that were previously thought to be adverse or lethal for life. Chile gathers a wide range of extreme environments: salars, geothermal springs, and geysers located at ...

Atacama Database: a platform of the microbiome of the Atacama Desert

Antonie van Leeuwenhoek, 2019
The Atacama Desert is one of the oldest and driest places on Earth. In the last decade, microbial richness and diversity has been acknowledged as an important biological resource of this region. Owing to the value of the microbial diversity apparent in potential biotechnology applications and conservation purposes, it is necessary to catalogue these ...

Unearthing the climate history of the Atacama Desert in northern Chile – deep drilling in two clay pans of the Coastal Cordillera [PDF]

Scientific Drilling
The Atacama Desert is one of the driest deserts on Earth, with a predominantly hyperarid climate since at least the Miocene. Geological evidence, however, indicates that this overall hyperaridity was repeatedly interrupted by wetter periods.

Ultraviolet radiation in the Atacama Desert

Antonie van Leeuwenhoek, 2018
The world's highest levels of surface ultraviolet (UV) irradiance have been measured in the Atacama Desert. This area is characterized by its high altitude, prevalent cloudless conditions, and a relatively low total ozone column. In this paper, we provide estimates of the surface UV (monthly UV index at noon and annual doses of UV-B and UV-A) for all ...

First observations of the aquatic invertebrate fauna in ephemeral Atacama River (22° S, Antofagasta Region, Chile) [PDF]

Desert, 2015
The invertebrate communities of the northern Chilean rivers are characterised by their marked endemism andspecificity of their community structure in different basins.

Leave no stone unturned: individually adapted xerotolerant Thaumarchaeota sheltered below the boulders of the Atacama Desert hyperarid core

Microbiome, 2021
Background The hyperarid core of the Atacama Desert is an extremely harsh environment thought to be colonized by only a few heterotrophic bacterial species.

On the importance of moisture conveyor belts from the tropical eastern Pacific for wetter conditions in the Atacama Desert during the mid-Pliocene [PDF]

Climate of the Past, 2023
Geomorphic and sedimentologic data indicate that the climate of today's hyper-arid Atacama Desert (northern Chile) was more humid during the mid-Pliocene to Late Pliocene.

Genetic studies of various Prosopis species (Leguminosae, Section Algarobia) co‐occurring in oases of the Atacama Desert (northern Chile)

Ecology and Evolution, 2021
In the Atacama Desert from northern Chile (19–24°S), Prosopis (Leguminosae) individuals are restricted to oases that are unevenly distributed and isolated from each other by large stretches of barren landscape constituting an interesting study model as ...

A new species of Ithome Chambers (Lepidoptera, Cosmopterigidae, Chrysopeleiinae) from the Atacama Desert revealed by morphology and DNA barcodes [PDF]

ZooKeys, 2020
Morphology and DNA barcode sequences were used to assess the taxonomic status of a micro-moth of the genus Ithome Chambers, 1875 (Lepidoptera, Cosmopterigidae, Chrysopeleiinae), whose larvae feed on inflorescences of Prosopis tamarugo Phil. (Fabaceae), a

Erosion after an extreme storm event in an arid fluvial system of the southern Atacama Desert: an assessment of the magnitude, return time, and conditioning factors of erosion and debris flow generation [PDF]

Natural Hazards and Earth System Sciences, 2020
The contribution of an individual extreme storm event to long-term erosion rates has been estimated for the first time in the Atacama Desert. A mean erosion of 1.3 mm has been calculated for the March 2015 event that impacted the southernmost part
