Geochemical, isotopic, and mineralogical constraints on atmospheric deposition in the hyper-arid Atacama Desert, Chile
Modern atmospheric deposition across the Atacama was collected by an array of dust traps that stretched from the Pacific coast to the Andean altiplano, and the material was analyzed for its geochemical, mass and isotopic composition. The coastal trap had the second-highest insoluble mineral particle and highest soluble salt deposition rates due to significant inputs from the Morro Mejillones Ra...
متن کاملStreptomyces atacamensis sp. nov., isolated from an extreme hyper-arid soil of the Atacama Desert, Chile.
The taxonomic position of a Streptomyces strain isolated from an extreme hyper-arid soil sample collected from the Atacama Desert was determined using a polyphasic approach. The strain, isolate C60(T), had chemical and morphological features typical of members of the genus Streptomyces and formed a distinct phyletic line in the Streptomyces 16S rRNA gene tree, together with the type strain of S...
متن کاملMicrobial colonization of halite from the hyper-arid Atacama Desert studied by Raman spectroscopy.
The hyper-arid core of the Atacama Desert (Chile) is the driest place on Earth and is considered a close analogue to the extremely arid conditions on the surface of Mars. Microbial life is very rare in soils of this hyper-arid region, and autotrophic micro-organisms are virtually absent. Instead, photosynthetic micro-organisms have successfully colonized the interior of halite crusts, which are...
متن کاملIgnimbrite textural properties as determinants of endolithic colonization patterns from hyper-arid Atacama Desert.
This study explores the photosynthetic microbial colonization of rhyolitic ignimbrites in Lomas de Tilocalar, a hyper-arid region of the Atacama Desert, Chile. Colonization appeared in the form of a green layer a few millimeters beneath the ignimbrite surface. Some ignimbrite rocks revealed two distinct micromorphological areas of identical mineralogical and chemical composition but different t...
متن کاملArchaea in a hyper-arid polar desert.
Studying the microbial diversity of a unique biome such as the McMurdo Dry Valleys, Antarctica, is important to understand the sustainability of life under cold-arid conditions where other forms of life (i.e., plants and animals) do not exist. Pointing et al. (1) examined multidomain microbial diversity in the McKelvey valley using culture-independent molecular approaches and interestingly foun...
