Fungal diversity in the Atacama Desert

Antonie van Leeuwenhoek, 2018
Fungi are generally easily dispersed, able to colonise a wide variety of substrata and can tolerate diverse environmental conditions. However, despite these abilities, the diversity of fungi in the Atacama Desert is practically unknown. Most of the resident fungi in desert regions are ubiquitous.

The Atacama Desert Trek: outcomes

Proceedings. 1998 IEEE International Conference on Robotics and Automation (Cat. No.98CH36146), 2002
In June and July 1997, Nomad, a planetary-relevant mobile robot, traversed more than 220 kilometers across the barren Atacama Desert in Chile, exploring a landscape analogous to the surfaces of the Moon and Mars. In this unprecedented demonstration, Nomad operated both autonomously and under the control of operators thousands of kilometers away ...

Preandean Atacama Desert Endolithic Microbiology

2020
Endolithic ecosystems are considered environmental refuges for life in arid and hyperarid deserts around the world. The microbial communities colonizing these habitats are of special interest due to their ability to live in a polyextreme environment characterized by scarcity of water and extreme solar radiation.

Geology and geochemistry of the Atacama Desert

Antonie van Leeuwenhoek, 2018
The Atacama Desert, the driest of its kind on Earth, hosts a number of unique geological and geochemical features that make it unlike any other environment on the planet. Considering its location on the western border of South America, between 17 and 28 °S, its climate has been characterized as arid to hyperarid for at least the past 10 million years ...

Marine Communities in the Atacama Desert

2019
Chapter 2 reviews ancient maritime communities for the hyperarid coast of northern Chile and southernmost Peru throughout the Holocene, with focus on the mid-Holocene Archaic Period. Two regions represent the exorheic and arheic coasts: Caleta Vitor (9,500 cal BP through the Inca occupation) and Copaco (mostly 7100 to 5200 cal BP), respectively ...

Carbon accrual in the Atacama Desert

Global and Planetary Change, 2019
Abstract The Atacama Desert is the oldest and driest desert on Earth, nevertheless traces of life have been observed in several places, accumulating residues of organic matter (OM) in the desert soil. We evaluated to which degree the distribution of soil organic carbon (SOC) stocks depends on aridity.

Microbial Life in the Atacama Desert

Science, 2004
In their Report “Mars-like soils in the Atacama Desert, Chile, and the dry limit of microbial life,” R. Navarro-Gonzales et al. found only very low levels of culturable bacteria in the Mars-like soils of the Atacama Desert, and they did not recover DNA (Reports, 7 Nov. 2003, p.

Atmospheric Water Uptake by an Atacama Desert Shrub

Science, 1980
Nolana mollis , a succulent-leaved shrub of the extreme coastal desert of Chile, has the capacity to condense water on its leaves out of unsaturated atmospheres, Metabolic energy would have to be expended to move this water either from the leaf surface directly to the mesophyll or, when dripped to the soil, from there into the ...

Neogene evaporites in desert volcanic environments: Atacama Desert, northern Chile

Sedimentology, 2001
The Upper Miocene and Pliocene evaporite deposits of the Atacama Desert of northern Chile (Hilaricos and Soledad Formations) are among the few non‐marine evaporites in which aridity not only formed the deposits, but has also preserved them almost unaltered under near‐surface conditions.
