    • DNA Metabarcoding of Deep-Sea Sediment Communities Using COI: Community Assessment, Spatio-Temporal Patterns and Comparison with 18S rDNA 

      Atienza, Sara; Guardiola, Magdalena; Præbel, Kim; Antich, Adrià; Turon, Xavier; Wangensteen Fuentes, Owen Simon (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-26)
      Among the complex ecosystems and habitats that form the deep sea, submarine canyons and open slope systems are regarded as potential hotspots of biodiversity. We assessed the spatial and temporal patterns of biodiversity in sediment communities of a NW Mediterranean Canyon and its adjacent open slope (Blanes Canyon) with DNA metabarcoding. We sampled three layers of sediment and four different depths ...

    • DNA metabarcoding of littoral hardbottom communities: high diversity and database gaps revealed by two molecular markers 

      Wangensteen Fuentes, Owen Simon; Palacín, Creu; Guardiola, Magdalena; Turon, Xavier (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-04)
      Biodiversity assessment of marine hard-bottom communities is hindered by the high diversity and size-ranges of the organisms present. We developed a DNA metabarcoding protocol for biodiversity characterization of structurally complex natural marine hard-bottom communities. We used two molecular markers: the “Leray fragment” of mitochondrial <i>cytochrome c oxidase</i> (COI), for which a novel primer ...
