Patterns of nematode diversity at hydrothermal vents on the East Pacific Rise

, 2006
The diversity and abundance of meiofauna in quasi-quantitative samples collected from Bathymodiolus mussel beds in a deep-sea hydrothermal vent field on the East Pacific Rise (EPR) was studied with particular reference to nematodes. Copepods, polychaetes

Understanding marine biodiversity patterns and drivers: The fall of Icarus

Marine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

Geochemical and Visual Indicators of Hydrothermal Fluid Flow through a Sediment-Hosted Volcanic Ridge in the Central Bransfield Basin (Antarctica) [PDF]

, 2013
In the austral summer of 2011 we undertook an investigation of three volcanic highs in the Central Bransfield Basin, Antarctica, in search of hydrothermal activity and associated fauna to assess changes since previous surveys and to evaluate the extent ...

Controls on faunal microdistribution and reproductive development in deep-sea chemosynthetic environments in the Antarctic

, 2014
There is no longer any part of the ocean that is inaccessible, however, spanning 361 million km2 across the earth's surface and, with approximately 50% of its volume at a depth greater than 2000 m, it is the very sheer size and complex nature of the deep

Ocean circulation contributes to genetic connectivity of limpet populations at deep‐sea hydrothermal vents in a back‐arc basin

Evolutionary Applications
For endemic benthos inhabiting hydrothermal vent fields, larval recruitment is critical for population maintenance and colonization via migration among separated sites. The vent‐endemic limpet, Lepetodrilus nux, is abundant at deep‐sea hydrothermal vents

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Natural warming differentiates communities and increases diversity in deep-sea Ridge Flank Hydrothermal Systems

Communications Biology
Ridge Flank Hydrothermal Systems have discrete pockets of fluid discharge that mimic climate-induced ocean warming. Unlike traditional hydrothermal fluids, those discharged by Ridge Flank Hydrothermal Systems have a chemical composition indistinguishable

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

Sedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

The geochemistry and geomicrobiology of relict hydrothermal sulphide deposits

, 2000
The diagenetic re-mineralisation of seafloor-sulphide deposits and the role of microbes in the metal-exchange processes were investigated in metalliferous sediments from the Alvin relict hydrothermal zone in the TAG area at 26º8'N (Mid-Atlantic Ridge ...

Archaeal communities as indicators of hydrothermal influence in the Tianxiu vent field, Northwest Indian Ocean

Frontiers in Microbiology
Deep-sea hydrothermal sediments represent critical zones for archaea-driven biogeochemical cycling, yet the ecological differentiation of archaeal communities across hydrothermal gradients remains poorly understood.
