      Environmental DNA (eDNA) metabarcoding (parallel sequencing of DNA/RNA for identification of whole communities within a targeted group) is revolutionizing the field of aquatic biomonitoring. To date, most metabarcoding ...
    • Eukaryotic biodiversity and spatial patterns in the Clarion-Clipperton Zone and other abyssal regions: insights from sediment DNA and RNA metabarcoding 

      Lejzerowicz, Franck; Gooday, Andrew J.; Barrenechea Angeles, Inès; Cordier, Tristan; Morard, Raphael; Apothéloz-Perret-Gentil, Laure; Lins, Lidia; Menot, Lenaick; Brandt, Angelika; Levin, Lisa A.; Martinez Arbizu, Pedro; Smith, Craig R.; Pawlowski, Jan (Journal article; Peer reviewed, 2021)
      The abyssal seafloor is a mosaic of highly diverse habitats that represent the least known marine ecosystems on Earth. Some regions enriched in natural resources, such as polymetallic nodules in the Clarion-Clipperton Zone ...
    • The global genetic diversity of planktonic foraminifera reveals the structure of cryptic speciation in plankton 

      Morard, Raphaël; Darling, Kate F.; Weiner, Agnes; Hassenrück, Christiane; Vanni, Chiara; Cordier, Tristan; Henry, Nicolas; Greco, Mattia; Vollmar, Nele Manon; Milivojevic, Tamara; Rahman, Shirin Nurshan; Siccha, Michael; Meilland, Julie; Jonkers, Lukas; Quillévéré, Frédéric; Escarguel, Gilles; Douady, Christophe J.; de Garidel-Thoron, Thibault; de Vargas, Colomban; Kucera, Michal (Peer reviewed; Journal article, 2024)
      The nature and extent of diversity in the plankton has fascinated scientists for over a century. Initially, the discovery of many new species in the remarkably uniform and unstructured pelagic environment appeared to ...
    • Patterns of eukaryotic diversity from the surface to the deep-ocean sediment 

      Cordier, Tristan; Angeles, Inès Barrenechea; Henry, Nicolas; Lejzerowicz, Franck; Berney, Cédric; Morard, Raphaël; Brandt, Angelika; Cambon-Bonavita, Marie-Anne; Guidi, Lionel; Lombard, Fabien; Arbizu, Pedro Martinez; Massana, Ramon; Orejas, Covadonga; Poulain, Julie; Smith, Craig R.; Wincker, Patrick; Arnaud-Haond, Sophie; Gooday, Andrew J.; de Vargas, Colomban; Pawlowski, Jan (Peer reviewed; Journal article, 2022)
      Remote deep-ocean sediment (DOS) ecosystems are among the least explored biomes on Earth. Genomic assessments of their biodiversity have failed to separate indigenous benthic organisms from sinking plankton. Here, we compare ...
