Epifaunal community structure associated with Riftia pachyptila aggregations in chemically different hydrothermal vent habitats ArchiMer
Govenar, B; Le Bris, Nadine; Gollner, S; Glanville, J; Aperghis, A; Hourdez, S; Fisher, C.
The vestimentiferan tubeworm Riftia pachyptila (Polychaeta: Sibloglinidae) often dominates early succession stages and high productivity habitats at low-temperature hydrothermal vents on the East Pacific Rise. We collected 8 aggregations of R. pachyptila and the associated epifaunal community at 2 discrete sites of diffuse hydrothermal activity, in December 2001 and December 2002. Because of the high spatial and temporal variability of the biotic and abiotic factors related to hydrothermal vent activity, significant differences in the structure and the composition of the community were expected to occur at the scale of either 1 yr or 500 m distance between very different sites. There was no significant difference in the temperature ranges of the diffuse...

Influence du vieillissement d'une population de crépidules sur l'épifaune associée. Influence sur le recrutement ArchiMer
Haubois, Anne-gaëlle.
Crepidula fornicata (slipper Iimpet) is a gastropod mollusc, coming from the North American east coast. Since its accidentaI introduction on french coasts, fifty years ago, C. fomicata invaded several coastal areas of this country and the bay of Saint Brieuc (Brittany -France) is one of the major site affected by the proliferation. Accumulation of dense mats of the slipper limpet contributes to the modification of the bottom structure and affects the substrate's heterogeneity, allowing the settlement of a diversified vagile and sessile epifauna. In this paper, the effects of the C. fornicata population ageing on epifauna assemblages and recruitment are studied. Quantitative and qualitative analysis of epifauna organisms suggests that, the ageing of the C....

Influence of surface texture and microhabitat heterogeneity in structuring nodule faunal communities ArchiMer
Veillette, J; Juniper, S; Gooday, A; Sarrazin, Jozee.
Manganese nodules provide an important habitat for sessile benthic organisms, many of them novel foraminifera, in the abyssal Pacific. The surface texture and microhabitat heterogeneity of nodules may play a significant role in structuring these communities. We analyzed the distribution of foraminiferal species on 20 nodules collected using either a USNEL box corer or the Nautile submersible sampling tool at a 5000-m-deep site in the Tropical North Pacific. The nodules had an upper region characterized by two microhabitats, namely raised surfaces and intervening depressed surfaces. The more or less vertical sides of the nodules were regarded as a third microhabitat. The upper region had a predominantly smooth texture while the sides had a rough texture. We...
