Ecological processes at deep-sea hydrothermal vents on fast-spreading mid-ocean ridges are punctuated by frequent physical disturbance, often accompanied by a high occurrence of population turnover. To persist through local extinction events, sessile invertebrate species living in these geologically and chemically dynamic habitats depend on larval dispersal. We characterized 12 polymorphic microsatellite loci from one such species, the siboglinid tubeworm Riftia pachyptila. All loci conformed to Hardy-Weinberg expectations without linkage (mean H(E) = 0.9405, mean N(A) = 20.25). These microsatellites are being employed in the investigation of spatial and temporal population genetic structure in the eastern Pacific Ocean. |
