Distinct contributions of suspended and sinking prokaryotes to mesopelagic carbon budget

Pauline Le Coq, Urania Christaki, France van Wambeke, Elisabeth Chevillon, Bruno Zakardjian, Marc Garel, Sophie Guasco, Chloé M J Baumas, Anne E Dekas, Patricia Bonin, Badr Al Ali, Maéva Gesson, Frédéric Le Moigne, Mireille Pujo- Pay, Olivier Crispi, Olivier Grosso, Thierry Moutin, Nagib Bhairy, Emmanuel de Saint Léger, Laurent Memery, Lionel Guidi, Fabrice Armougom, Hans-Peter Grossart, Christian Tamburini

The mesopelagic zone, between 100 and 1000 meters depth, is a crucial layer, in which carbon preliminary coming down from the surface is transformed before a portion makes it into the deep ocean. While eddies and their fronts influence surface productivity and carbon export, their effects deeper in…

Exploring microbial and metabolite composition of the external mucus of wild Mediterranean sparids: is there a link with their monogenean ectoparasites?

Judith Revault, Delphine Raviglione, Yves Desdevises, Elodie Magnanou, Nathalie Tapissier-Bontemps

Background External mucus forms a complex interface that constitutes the first line of defense in teleost fish. In addition to host-derived molecules, this mucus harbors bacterial communities capable of producing a wide range of bioactive compounds. The structure and function of these microbial and…

Tara Polaris expeditions: seasonal and long-term contaminant monitoring in the changing central Arctic

Jean-François Ghiglione, Lars-Eric Heimbürger-Boavida, Marion Fourquez, Ian Hough, Jeroen E. Sonke, Alexandra ter Halle, Kathy S. Law, Julia Schmale, J. Michel Flores, Julien Gigault, Mathieu Ardyna, Stephen Kohler, Zhiyong Xie, Jay Cullen, Maxime Geoffroy, Clémentine Moulin, Romain Troublé, Lee Karp-Boss, Chris Bowler, Marcel Babin, Hélène Angot

The central Arctic atmosphere, cryosphere, hydrosphere and biosphere, is heavily impacted by anthropogenic activities. While some contaminants originate from local activities, the majority are transported over long distances via rivers, ocean currents, and atmospheric pathways. Contaminants can…
