Microbial ecology of deep-sea hypersaline anoxic basins.
TL;DR: Current knowledge of the diversity, genomics, metabolisms and ecology of prokaryotes in DHABs, characterized by prolonged historical separation of the brines from the upper water column, is reviewed.

Direct quantification of ecological drift at the population level in synthetic bacterial communities.
TL;DR: The results provide quantitative insights regarding the properties of drift in bacterial communities and suggest that it accounts for a consistent fraction of the observed stochasticity in natural surveys.
Discovery of Afifi, the shallowest and southernmost brine pool reported in the Red Sea
Carlos M. Duarte,Anders Røstad,Grégoire Michoud,Alan Barozzi,Giuseppe Merlino,Antonio Delgado-Huertas,Antonio Delgado-Huertas,Brian C. Hession,Francis L. Mallon,Abdulakader M. Afifi,Daniele Daffonchio +10 more
TL;DR: The Afifi brine show a linear increase in δ 18 O and δD relative to seawater that differs from the others Red Sea brine pools, indicating a non-hydrothermal origin, compatible with enrichment in evaporitic environments.
Fine-scale metabolic discontinuity in a stratified prokaryote microbiome of a Red Sea deep halocline.
Grégoire Michoud,David Kamanda Ngugi,David Kamanda Ngugi,Alan Barozzi,Giuseppe Merlino,Maria Ll. Calleja,Maria Ll. Calleja,Antonio Delgado-Huertas,Xosé Anxelu G. Morán,Daniele Daffonchio +9 more
TL;DR: In this article, the authors applied high-precision sampling of the brine-seawater transition interface in the Suakin Deep, located at 2770m in the central Red Sea, to reveal previously undocumented fine-scale community structuring and succession of metabolic groups along a salinity gradient only 1'm thick.
Enzyme adaptation to habitat thermal legacy shapes the thermal plasticity of marine microbiomes

TL;DR: In this article , the authors quantified the thermal behavior of seven functionally independent enzyme classes (esterase, extradiol dioxygenase, phosphatase, beta-galactosidase, nuclease, transaminase, and aldo-keto reductase) in native proteomes of marine sediment microbiomes from the Irish Sea to the southern Red Sea.
