Ecophysiological study of green microalgae isolated from the grit crust of the Atacama Desert. [PDF]
Abstract Terrestrial algae play a critical, yet often overlooked, role in the functioning of biological soil crusts (biocrusts), which are considered microecosystems, particularly in extreme environments. This study investigated the ecophysiological traits of green algae isolated from the grit crust—a unique biocrust type reported a few years ago in ...

Fog, Symbiosis, and Survival: The Ecological Architecture of the Grit Crust From the Atacama Desert Represents a Lichen Holobiome Rather Than a Soil Microbiome. [PDF]
Multi‐marker metabarcoding (16S rRNA, 18S rRNA, ITS2) of the fog‐dependent grit crust in the Atacama Desert reveals a community structured by lichen symbioses rather than typical soil‐derived microbial assemblages. The green algal photobiont Trebouxia dominates the eukaryotic community, accompanied by lichenized Caliciales and lichen‐associated ...

Introducing the Atacama Desert [PDF]
This brief introduction is intended to orientate the reader with respect to the principal environmental and historical features of the Atacama Desert, the oldest and continuously driest non-polar temperate desert on Earth. Exploration of its microbiology is relatively recent but both fundamental and applied research activities have grown dramatically ...

Elevational variation in heart mass and suppression of hypoxia-induced right ventricle hypertrophy in Andean leaf-eared mice (Phyllotis). [PDF]
Abstract figure legend In lowland mammals that ascend to high elevation, hypoxia‐induced changes in the pulmonary circulation can give rise to hypoxic pulmonary hypertension (HPH) and associated right‐ventricle (RV) hypertrophy. Andean mice with broad elevational ranges have greater heart mass relative to body size at higher elevations, but they ...

The Solar Spectrum in the Atacama Desert [PDF]
AbstractThe Atacama Desert has been pointed out as one of the places on earth where the highest surface irradiance may occur. This area is characterized by its high altitude, prevalent cloudless conditions and relatively low columns of ozone and water vapor.

Atacama compact array antennas [PDF]
We report major performance test results of the Atacama Compact Array (ACA) 7-m and 12-m antennas of ALMA (Atacama Large Millimeter/submillimeter Array). The four major performances of the ACA antennas are all-sky pointing (to be not more than 2.0 arcsec), offset pointing (to be < 0.6 arcsec) surface accuracy (< 25(20) micrometer for 12(7)m ...
