“…But this trend should not be extrapolated to the continental slope and deeper habitats. Seventy-five percent of Recent deep-sea hydrothermal vent mussels showed shell repairs (Rhoads et al, 1982). Rex (1988, 1989) reported repair frequencies (percent of specimens with scars) between 0.8 and 0.48 for prosobranch gastropods from communities below 200 m depths in the Western North Atlantic.…”

“…The population structure of mytilid bivalves from hydrothermal vents has never been studied in detail, although length-frequency histograms have been published by Rhoads et al (1982), Smith (1985) and Hessler et al (1988) for Bathymodiolus therrnophilus from the Galapagos Rift vents without any interpretation in terms of population dynamics. Preliminary results on population structure of the mytllid bivalves of Lucky Strike have also been published by Comtet (1994) and Van Dover et al (1996), from 4 samples collected in June 1993 from 3 sites at Lucky Strike, and suggested a discontinuous recruitment.…”

Population structure and recruitment pattern of undescribed mytilid bivalves that dominate the animal communities associated with vents of the Lucky Stnke and Menez Gwen hydrothermal vent fields (37" 17' N and 37" 50' N on the Mid-Atlantic Ridge) were studled from size-frequency analyses. Intra-site comparisons reveal that length-frequency distributions differ significantly from one location to the other. This spatial segregation of the sizes could be due to spatio-temporal variability in environmental conditions and to intraspecific competition processes, especially adult-larval interactions (competition for space and food resources, intraspecific larviphagy) that could prevent larvae from settling on surfaces covered by adults. A modal decomposition analysis was conducted after pooling samples collected from different locations at the same site. Polymodal structure of length-frequency distributions indicates that recruitment is likely discontinuous in time. The presence of postlarvae in each population of the Lucky Strike vent field suggests that a recruitment event took place just before sampling in June 1994, and that mytilid recruitment is synchronized between sites, which is confirmed by the comparison of modal values. Length-frequency distribution of the Menez Gwen mytilid population displays similar modal values, especially for the smallest mode. This suggests a synchronization of the recruitment between the 2 vent fields, which are separated by a distance of 60 km. No seasonal pattern in recruitment could be Identified although newly recruited individuals were observed in June 1993 on Lucky Strike sites.

“…While these fish may not be regular predators on the clams, they certainly appear capable of feeding on recently dead individuals. The abundance of colonylike groups of still-articulated valves seen at these and other sites suggests that clam colonies are rarely disturbed by large predators or scavengers (Rhoads et al 1982, Hessler et al 1985. The omnivorous galatheid crabs seen at the Tenryu Canyon site likely scavenge dead clams as well as deposit feeding on organic debris.…”

Submersible exploration of the Japan subduction zones has revealed benthic communities dominated by clams (Calyptogena spp.) around sed~ment porewater seeps at depths from 3850 to 6000 m. Photographic and video records were used to produce microcartographlc reconstructions of 3 contrasting cold seep sites. Spatial and abundance relations of megafauna lead us to propose several hypotheses regard~ng the ecological functioning of these cold seep communities. W e dlst~nguish between the likely direct use of reducing substances in venting fluids by Calyptogena-bacteria symbioses and indirect usage by accompanying abyssal species not known to harbour symbionts. Microdistribution and known or presumed feedmg modes of the accompanying species indicate 2 different sources of organic matter enrichment within cold seep sites: organic debris originating from bivalve colonies, and enrichment of extensive areas of surrounding surface sediments where weaker, more hffuse porewater seepage may support chemosynthetic production by free-living bacteria. The occurrence of colony-like groupings of empty Calyptogena valves indicates that cold seeps are ephemeral, with groups of living clams, mixed living and dead clams, and empty dissolving shells marlung the course of a cycle of porewater venting and offering clues to the recent history of cold seep activity.
