Abstract The Afar Depression is a unique place on Earth where active rift processes can be
directly observed. It is believed to be close to continental breakup. The Afar hotspot has a …

Hypersaline endorheic aquatic systems (H-SEAS) are lakes/shallow playas in arid and
semiarid regions that undergo extreme oscillations in salinity and severe drought episodes …

Our understanding of the microbial diversity inhabiting hypersaline environments, here
defined as containing> 100–150 g/L salts, has greatly increased in the past five years …

Abstract Extremely halophilic archaea (Haloarchaea, Nanohaloarchaeota,
Methanonatronarchaeia and Halarchaeoplasmatales) thrive in saturating salt concentrations …

Few described archaeal, and fewer bacterial, lineages thrive under salt-saturating
conditions, such as solar saltern crystallizers (salinity above 30% w/v). They accumulate …

Mt. Erebus, Antarctica, is the world's southernmost active volcano and is unique in its
isolation from other major active volcanic systems and its distinctive geothermal systems …

Determining the precise limits of life in polyextreme environments is challenging. Studies
along gradients of polyextreme conditions in the Dallol proto-volcano area (Danakil salt …

Extreme environments, including hypersaline pools, often serve as biogeographical islands.
Putative colonizers would need to survive transport across potentially vast distances of …

Hypersaline-adapted archaea, or haloarchaea, inhabit extreme environments where
changes in near-saturated salinity, oxygen, and nutrients require rapid regulation of …

Resumen Microorganisms dominate Earth. They represent a biomass of approximately 70
gigatons of carbon, only surpassed by plants (Jo, Oh, and Park 2020), and are present in all …
