Última De nouveaux systèmes hôtes-virus associés aux sources hydrothermales océaniques profondes ArchiMer Boyer, Coraline. Our knowledge of the viral diversity associated to microorganisms inhabiting the deep-sea hydrothermal vents is still limited. Only a few studies have focused on viral abundance and impact on microbial mortality within these ecosystems. A limited number of viruses (6 bacterioviruses and 2 archaeoviruses) were isolated from these environments and characterized. Two viruses associated to hyperthermophilic anaerobic Archaea, from the Thermococcales order, have been described in our laboratory. In order to deepen our knowledge on the viral diversity of these extreme environments, we have extended our investigation to the bacterial order of Thermotogales. This order is composed of anaerobic chemoorganotrophic bacteria that are, for the most part,...

Deep-water hydrothermal vent host high-biomass communities based on chemoautotrophy supported by the metabolic activity of free-living and symbiotic bacteria associated to invertebrates, especially megafauna. Knowledge on the mechanisms of dispersal and the life cycle of vent species is essential to our understanding of the vent communities in terms of distribution, structure and temporal variation. In this study, I present some advances regarding the dispersal and life cycle of a dominant species of the Mid-Atlantic Ridge (MAR) vent ecosystems, the alvinocaridid shrimp Rimicaris exoculata, and other related species. The methodological approaches applied include morphological descriptions of larvae, analysis of population biology and reproduction, and...
