TL;DR: Results show that the less reduced, hydrogen-poor fluids at Lucky Strike limit colonization by strict anaerobes such as methanogens, and allow for hyperthermophilic microaerophiles, like Aeropyrum.

TL;DR: Results show that microbial communities associated with hydrothermal vent deposits in back-arc basins are taxonomically similar to those from mid-ocean ridge systems, but differences in geologic processes between vent fields in aBack-arc basin can influence microbial community structure.

TL;DR: Based on phylogenetic, physiological and genomic data, Ncl-1 and NZ3T represent novel genera in the Nanoarchaeota and the Desulfurococcaceae, respectively, with the proposed names Candidatus Nanoclepta minutus and Zestosphaera tikiterensis.

TL;DR: In insights into how microbial community composition and function reflect subtly different fluid chemistries resulting from subsurface fluid interactions with distinct alteration mineral assemblages, it is shown that these systems represent oases of phylogenetically diverse Archaea and Bacteria.

TL;DR: The initial results show that the metatranscriptomes in these similar Aquificales-dominated communities can reveal community-level gene function in geochemically distinct thermal environments, suggesting the presence of microdiversity among Sulfurihydrogenibium populations in situ.
