Characterization of 12 polymorphic microsatellite loci in Ifremeria nautilei, a chemoautotrophic gastropod from deep-sea hydrothermal vents
Ifremeria nautilei is deep-sea provannid gastropod endemic to hydrothermal vents at southwest Pacific back-arc spreading centers. Twelve, selectively neutral and unlinked polymorphic microsatellite loci were developed for this species. Three loci deviated significantly from Hardy–Weinberg expectations. Average observed heterozygosity ranged from 0.719 to 0.906 (mean HO = 0.547, SD = 0.206). Three of the 12 loci cross-amplified in two species of Alviniconcha (Provannidae) that co-occur with I. nautilei at Pacific vent habitats. Microsatellites developed for I. nautilei are being deployed to study connectivity among populations of this species colonizing geographically discrete back-arc basin vent systems.
