    • The costs and trade-offs of optimal foraging in marine fish larvae 

      Hauss, Helena; Schwabe, Laura; Peck, Myron A. (Peer reviewed; Journal article, 2023)
      In a warming world, both the metabolic rates of ectotherm predators and the phenology of their prey organisms is subject to change. Knowledge on how intrinsic and extrinsic factors govern predator–prey interactions is ...

    • Experimental mining plumes and ocean warming trigger stress in a deep pelagic jellyfish 

      Stenvers, Vanessa; Hauss, Helena; Bayer, Till; Havermans, Charlotte; Hentschel, Ute; Schmittmann, Lara; Sweetman, Andrew K.; Hoving, Henk-Jan T. (Peer reviewed; Journal article, 2023)
      The deep pelagic ocean is increasingly subjected to human-induced environmental change. While pelagic animals provide important ecosystem functions including climate regulation, species-specific responses to stressors ...

    • Hypoxia-tolerant zooplankton may reduce biological carbon pump efficiency in the Humboldt current system off Peru 

      Engel, Anja; Cisternas-Novoa, Carolina; Hauss, Helena; Kiko, Rainer; LeMoigne, Frederic (Journal article; Peer reviewed, 2023)
      In the ocean, downward flux of particles produced in sunlit surface waters is the major component of the biological carbon pump, which sequesters atmospheric carbon dioxide and fuels deep-sea ecosystems. The efficiency of ...

    • Nitrogen fixation rates in the Guinea Dome and the equatorial upwelling regions in the Atlantic Ocean 

      Fernández‑Carrera, Ana; Kiko, Rainer; Hauss, Helena; Hamilton, Douglas S.; Achterberg, Eric P.; Montoya, Joseph P.; Dengler, Marcus; Brandt, Peter; Subranamiam, Ajit (Peer reviewed; Journal article, 2023)
      Biological nitrogen fixation is a key process balancing the loss of combined nitrogen in the marine nitrogen cycle. Its relevance in upwelling or high nutrient regions is still unclear, with the few available studies in ...

    • Three major mesoplanktonic communities resolved by in situ imaging in the upper 500 m of the global ocean 

      Panaïotis, Thelma; Babin, Marcel; Biard, Tristan; Carlotti, François; Coppola, Laurent; Guidi, Lionel; Hauss, Helena; Karp‐Boss, Lee; Kiko, Rainer; Lombard, Fabien; McDonnell, Andrew M.P.; Picheral, Marc; Rogge, Andreas; Waite, Anya M.; Stemmann, Lars; Irisson, Jean-Olivier (Peer reviewed; Journal article, 2023)
      Aim The distribution of mesoplankton communities has been poorly studied at global scale, especially from in situ instruments. This study aims to (1) describe the global distribution of mesoplankton communities in relation ...
