Roots as a site of hydrogen sulfide uptake in the hydrocarbon seep vestimentiferan Lamellibrachia sp.
The characteristics of the root suggest that it reaches down to the higher sulfide levels present in the deeper sediment and that it functions to increase the surface area available for sulfide uptake in a manner analogous to a respiratory organ. Expand
Early steps in microbial colonization processes at deep-sea hydrothermal vents.
A pluri-disciplinary in situ colonization experiment was performed to study early stages of colonization in deep-sea vent Alvinella spp. worm habitats. Four colonization devices were deployed ontoExpand
Wide bacterial diversity associated with tubes of the vent worm Riftia pachyptila.
The bacterial diversity found suggests that complex metabolic interactions, particularly based on sulphur chemistry, may be occurring in different microniches of the R. pachyptila tubes. Expand
Biology and ecology of the “Pompeii worm” (Alvinella pompejana Desbruyères and Laubier), a normal dweller of an extreme deep-sea environment: A synthesis of current knowledge and recent developments
Abstract Alvinella pompejana, the “Pompeii worm” lives on active hydrothermal edifices at deep-sea vents of the East Pacific Rise. The physical and chemical patterns of its microhabitat wereExpand
Unexpected co-occurrence of six bacterial symbionts in the gills of the cold seep mussel Idas sp. (Bivalvia: Mytilidae).
The report of a multiple symbiosis involving six distinct bacterial 16S rRNA phylotypes in a small Idas mussel found on carbonate crusts in a cold seep area located north to the Nile deep-sea fan shows that symbiont diversity has probably been underestimated, and questions whether the common ancestor of bathymodioline mussels was associated with multiple bacteria.

Rapid Microbial Production of Filamentous Sulfur Mats at Hydrothermal Vents
Observed formation of filamentous sulfur mats by a new chemoautotrophic, hydrogen sulfide-oxidizing bacterium suggest that formation of these sulfur mats may be a factor in the initial colonization of hydrothermal surfaces by macrofaunal Alvinella worms. Expand
Pressure and life: some biological strategies
This review will focus on the consequences of pressure changes on various biological processes, and more specifically on animals living in the deep-sea, and recent data illustrating the diversity of effects pressure may have at different levels in biological systems, with particular attention to effects on gene expression.

Food web indicators under the Marine Strategy Framework Directive: From complexity to simplicity?
The existing suite of indicators gives variable focus to the three important food web properties: structure, functioning and dynamics, and more emphasis should be given to the latter two and the general principles that relate these three properties. Expand
Colonization of organic substrates deployed in deep-sea reducing habitats by symbiotic species and associated fauna.
Test whether typical vent/seep organisms harbouring symbionts or not, would be able to settle on organic substrates deployed in the vicinity of chemosynthetic ecosystems attracted both fauna relying on chemosynthesis-derived carbon as well as fauna relied on heterotrophy the latter being opportunistic and tolerant to sulphide.

Altered synthesis of laminin 1 and absence of basement membrane component deposition in (beta)1 integrin-deficient embryoid bodies.
Results indicate that (beta)1 integrins are required for the initiation of basement membrane formation, presumably by applying a feed-back regulation on the expression of laminin (alpha)1 chain and other components of basement membranes. Expand
