    • Cryptic frenulates are the dominant chemosymbiotrophic fauna at Arctic and high latitude Atlantic cold seeps 

      Sen, Arunima; Duperron, Sebastien; Hourdez, Stephane; Piquet, Berenice; Léger, Nelly; Gebruk, Andrey; Le Port, Anne-Sophie; Svenning, Mette Marianne; Andersen, Ann C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-28)
      We provide the first detailed identification of Barents Sea cold seep frenulate hosts and their symbionts. Mitochondrial COI sequence analysis, in combination with detailed morphological investigations through both light and electron microscopy was used for identifying frenulate hosts, and comparing them to Oligobrachia haakonmosbiensis and Oligobrachia webbi, two morphologically similar species ...

    • Frenulate siboglinids at high Arctic methane seeps and insight into high latitude frenulate distribution 

      Sen, Arunima; Didriksen, Alena; Hourdez, Stephane; Svenning, Mette Marianne; Rasmussen, Tine Lander (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-09)
      Frenulate species were identified from a high Arctic methane seep area on Vestnesa Ridge, western Svalbard margin (79°N, Fram Strait) based on mitochondrial cytochrome oxidase subunit I (mtCOI). Two species were found: <i>Oligobrachia haakonmosbiensis</i>, and a new, distinct, and undescribed <i>Oligobrachia</i> species. The new species adds to the cryptic <i>Oligobrachia</i> species complex found ...
