The phylogeography and ecology of oligobrachia frenulate species suggest a generalist chemosynthesis-based fauna in the arctic
International audience We used ancient DNA (aDNA) extraction methods to sequence museum voucher samples of Oligobrachia webbi, a frenulate siboglinid polychaete described from a northern Norwegian fjord over fifty years ago. Our sequencing results indicate a genetic match with the cryptic seep speci...
