      Due to climate change, decreasing ice cover and increasing industrial activities, Arctic marine ecosystems are expected to face higher levels of anthropogenic stress. To sustain healthy and productive ocean ecosystems, it ...
    • “Candidatus Ethanoperedens,” a thermophilic genus of archaea mediating the anaerobic oxidation of ethane 

      Hahn, Cedric Jasper; Laso-Pérez, Rafael; Vulcano, Francesca; Vaziourakis, Konstantinos-Marios; Stokke, Runar; Steen, Ida Helene; Teske, Andreas; Boetius, Antje; Liebeke, Manuel; Amann, Rudolf; Knittel, Katrin; Wegener, Gunter (Journal article; Peer reviewed, 2020)
      Cold seeps and hydrothermal vents deliver large amounts of methane and other gaseous alkanes into marine surface sediments. Consortia of archaea and partner bacteria thrive on the oxidation of these alkanes and its coupling ...
    • Hot Vents Beneath an Icy Ocean: The Aurora Vent Field, Gakkel Ridge, Revealed 

      Ramirez-Llodra, Eva; Argentino, Claudio; Baker, Maria; Boetius, Antje; Costa, Carolina; Dahle, Håkon; Denny, Emily Maria; Dessandier, Pierre-Antoine; Eilertsen, Mari Heggernes; Ferré, Benedicte; German, Cristopher R.; Hand, Kevin; Hilário, Ana; Hislop, Lawrence; Jamieson, John W.; Kalenitchenko, Dimitri; Mall, Achim; Panieri, Giuliana; Purser, Autun; Ramalho, Sofia P.; Reeves, Eoghan; Rolley, Leighton; Pereira, Samuel; de Azevedo Ribeiro, Pedro Miguel; Sert, Muhammed Fatih; Steen, Ida Helene; Stetzler, Marie Helene Paula; Stokke, Runar; Victorero, Lissette; Vulcano, Francesca; Vågenes, Stig; Waghorn, Kate Alyse; Bünz, Stefan (Journal article; Peer reviewed, 2022)
      Evidence of hydrothermal venting on the ultra-slow spreading Gakkel Ridge in the Central Arctic Ocean has been available since 2001, with first visual evidence of black smokers on the Aurora Vent Field obtained in 2014. ...
    • Hydrothermal activity fuels microbial sulfate reduction in deep and distal marine settings along the Arctic Mid Ocean Ridges 

      Roerdink, Desiree Lisette; Vulcano, Francesca; Landro, Jan-Kristoffer; Moltubakk, Karen Elisabeth; Babel, Hannah Rose; Jørgensen, Steffen Leth; Baumberger, Tamara; Økland, Ingeborg Elisabet; Reeves, Eoghan; Thorseth, Ingunn Hindenes; Reigstad, Laila Johanne; Strauss, Harald; Steen, Ida Helene (Journal article; Peer reviewed, 2023)
      Microbial sulfate reduction is generally limited in the deep sea compared to shallower marine environments, but cold seeps and hydrothermal systems are considered an exception. Here, we report sulfate reduction rates and ...
    • Metagenomics-driven predictions in Archaea from hydrocarbon-rich Arctic hydrothermal systems: Phylogenetic and metabolic analyses of methane and short-chain alkane-degrading lineages 

      Vulcano, Francesca (Doctoral thesis, 2023-04-14)
      Metan og hydrokarboner er potente klimagasser som produseres og nedbrytes hovedsakelig biotisk. I havet akkumuleres metan og hydrokarboner i sedimenter og hydrotermiske systemer. Nylige metagenomstudier har utvidet mangfoldet ...
    • Phylogenetic and functional diverse ANME-1 thrive in Arctic hydrothermal vents 

      Vulcano, Francesca; Hahn, Cedric Jasper; Roerdink, Desiree Lisette; Dahle, Håkon; Reeves, Eoghan; Wegener, Gunter; Steen, Ida Helene; Stokke, Runar (Journal article; Peer reviewed, 2022)
      The methane-rich areas, the Loki's Castle vent field and the Jan Mayen vent field at the Arctic Mid Ocean Ridge (AMOR), host abundant niches for anaerobic methane-oxidizers, which are predominantly filled by members of the ...
    • Potential for homoacetogenesis via the Wood–Ljungdahl pathway in Korarchaeia lineages from marine hydrothermal vents 

      Vulcano, Francesca; Hribovšek, Petra; Denny, Emily Maria; Steen, Ida Helene; Stokke, Runar (Journal article; Peer reviewed, 2023)
      The Wood–Ljungdahl pathway (WLP) is a key metabolic component of acetogenic bacteria where it acts as an electron sink. In Archaea, despite traditionally being linked to methanogenesis, the pathway has been found in several ...
    • Tailoring Hydrothermal Vent Biodiversity Toward Improved Biodiscovery Using a Novel in situ Enrichment Strategy 

      Stokke, Runar; Reeves, Eoghan; Dahle, Håkon; Fedøy, Anita-Elin; Viflot, Thomas Øfstegaard; Onstad, Solveig L.; Vulcano, Francesca; Pedersen, Rolf Birger; Eijsink, Vincent; Steen, Ida Helene (Journal article; Peer reviewed, 2020)
      Deep-sea hydrothermal vents are amongst the most extreme environments on Earth and represent interesting targets for marine bioprospecting and biodiscovery. The microbial communities in hydrothermal vents are often dominated ...
