Hydrothermal vent ecosystems and representative hyperthermophilic microorganisms
One of the most spectacular events of the present century, concerning all biological and environmental disciplines, was the discovery of deep-sea hydrothermal vents around the Galapagos Islands, during the late 1970s. This remarkable scientific accomplishment was achieved thanks to the extensive work carried out by oceanographers and geologists. A significant role in terms of scientific support...
متن کاملDiffuse flow environments within basalt- and sediment-based hydrothermal vent ecosystems harbor specialized microbial communities
Hydrothermal vents differ both in surface input and subsurface geochemistry. The effects of these differences on their microbial communities are not clear. Here, we investigated both alpha and beta diversity of diffuse flow-associated microbial communities emanating from vents at a basalt-based hydrothermal system along the East Pacific Rise (EPR) and a sediment-based hydrothermal system, Guaym...
متن کاملEvolutionary Strategies of Viruses, Bacteria and Archaea in Hydrothermal Vent Ecosystems Revealed through Metagenomics
The deep-sea hydrothermal vent habitat hosts a diverse community of archaea and bacteria that withstand extreme fluctuations in environmental conditions. Abundant viruses in these systems, a high proportion of which are lysogenic, must also withstand these environmental extremes. Here, we explore the evolutionary strategies of both microorganisms and viruses in hydrothermal systems through comp...
متن کاملEditorial: Hydrothermal microbial ecosystems
The papers in the " Hydrothermal Vent " research topic cover a range of microbiological research in deep and shallow hydrothermal environments, from high temperature " black smokers, " to diffuse flow habitats and episodically discharging subsurface fluids, to the hydrothermal plumes. Together they provide a snapshot of current research interests in a field that has evolved rapidly since the di...
متن کاملThe hydrothermal vent bivalve Bathymodiolus azoricus
Hydrothermal environments are characterised by high metal concentrations related to interactions of the convective seawater circulation with basaltic rocks inside the ocean crust. Thus, hydrothermal fluids are enriched with, among other toxic metals, mercury (Hg) that becomes bioavailable to vent macro invertebrates and that may determine development of specialised defence mechanisms. Unusually...
