Abstract
    Despite the fragmented nature of hydrothermal vent (HV) fields, nascent vent sites are rapidly colonized by a pool of regional species. While succession of large animals at vents is relatively well established, we lack information on the associated meiofauna, in particular, on nematodes. The aim of the present study is to investigate the process of colonisation after 9 months of organic (wood and bone) and inorganic (slate) substrata by nematode assemblages deployed at the Eiffel Tower hydrothermal edifice on the Lucky Strike vent field on the Mid-Atlantic Ridge (MAR), at varying distances from visible hydrothermal activity. Abundance, biomass and diversity of colonising nematodes were compared with the results from an earlier similar two-year experiment. Near the vents, nematodes preferred inorganic substrata while in areas not influenced by vent activity, organic substrata were preferred. Nematode females dominated at almost all sites while numerous females at the ovigerous stage and juveniles were reported near the vent emissions, suggesting that nematode populations reproduce well after just 9 months. Our nine-month experiment on the MAR showed that the type of substratum influenced significantly the composition of colonising nematodes, while after two years, the community structure was instead influenced by hydrothermal activity.
