Data from: Molecular study of bacterial diversity within the trophosome of the vestimentiferan tubeworm Ridgeia piscesae
A large proportion of the faunal biomass in hydrothermal vent ecosystems relies on symbiotic relationships, with bacteria as a source of nutrition. Whereas multiple symbioses have been observed in diverse vent hosts, siboglinid tubeworms have been thought to harbour a single endosymbiont phylotype affiliated to the Gammaproteobacteria. In the case of the Northeast Pacific vestimentiferan Ridgeia piscesae, two previous studies suggested the presence of more than one symbiont. The possibility of multiple, and possibly habitat-specific, symbionts in R. piscesae provided a potential explanation for the tubeworm's broad ecological niche, compared with other hydrothermal vent siboglinids. This study further explored the diversity of trophosome bacteria in R. piscesae using two methodological approaches not yet applied to this symbiosis. We carried out 454-pyrosequencing on trophosome samples from 46 individual worms and used catalyzed reporter deposition-fluorescence in situ hybridization (CARD-FISH) to verify the presence of the major groups detected in the pyrotag data. Both methods yielded inconsistent and sometimes contradictory results between sampling sites, and neither provided irrefutable evidence for the presence of symbionts other than the expected Gammaproteobacteria. We therefore conclude that the other adaptive mechanisms must be considered to explain the broad physico-chemical niche occupied by the different growth forms of R. piscesae.
Data from: Free-living bacterial communities associated with tubeworm (Ridgeia piscesae) aggregations in contrasting diffuse flow hydrothermal vent habitats at the Main Endeavour Field, Juan de Fuca Ridge
We systematically studied free-living bacterial diversity within aggregations of the vestimentiferan tubeworm Ridgeia piscesae sampled from two contrasting flow regimes (High Flow and Low Flow) in the Endeavour Hydrothermal Vents Marine Protected Area (MPA) on the Juan de Fuca Ridge (Northeast Pacific). Eight samples of particulate detritus were recovered from paired tubeworm grabs from four vent sites. Most sequences (454 tag and Sanger methods) were affiliated to the Epsilonproteobacteria, and the sulfur-oxidizing genus Sulfurovum was dominant in all samples. Gammaproteobacteria were also detected, mainly in Low Flow sequence libraries, and were affiliated with known methanotrophs and decomposers. The cooccurrence of sulfur reducers from the Deltaproteobac- teria and the Epsilonproteobacteria suggests internal sulfur cycling within these habitats. Other phyla detected included Bacteroidetes, Actinobacteria, Chloroflexi, Firmicutes, Planctomycetes, Verrucomicrobia, and Deinococcus–Thermus. Statisti- cally significant relationships between sequence library composition and habitat type suggest a predictable pattern for High Flow and Low Flow environments. Most sequences significantly more represented in High Flow libraries were related to sulfur and hydrogen oxidizers, while mainly heterotrophic groups were more represented in Low Flow libraries. Differences in temperature, avail- able energy for metabolism, and stability between High Flow and Low Flow habitats potentially explain their distinct bacterial communities.
