Diversity of cultured photosynthetic flagellates in the northeast Pacific and Arctic Oceans in summer ArchiMer
Balzano, S.; Gourvil, P.; Siano, Raffaele; Chanoine, M.; Marie, D.; Lessard, S.; Sarno, D.; Vaulot, Daniel.
During the MALINA cruise (summer 2009), an extensive effort was undertaken to isolate phytoplankton strains from the northeast (NE) Pacific Ocean, the Bering Strait, the Chukchi Sea, and the Beaufort Sea. In order to characterise the main photosynthetic microorganisms occurring in the Arctic during the summer season, strains were isolated by flow cytometry sorting (FCS) and single cell pipetting before or after phytoplankton enrichment of seawater samples. Strains were isolated both onboard and back in the laboratory and cultured at 4 °C under light/dark conditions. Overall, we isolated and characterised by light microscopy and 18 S rRNA gene sequencing 104 strains of photosynthetic flagellates which grouped into 21 genotypes (defined by 99.5% 18 S rRNA...

Interactions between the ocean and the atmosphere occur at the air-sea interface through the transfer of momentum, heat, gases and particulate matter, and through the impact of the upper-ocean biology on the composition and radiative properties of this boundary layer. The Tara Pacific expedition, launched in May 2016 aboard the schooner Tara, was a 29-month exploration with the dual goals to study the ecology of reef ecosystems along ecological gradients in the Pacific Ocean and to assess inter-island and open ocean surface plankton and neuston community structures. In addition, key atmospheric properties were measured to study links between the two boundary layer properties. A major challenge for the open ocean sampling was the lack of ship-time available...

Is the distribution of Prochlorococcus and Synechococcus ecotypes in the Mediterranean Sea affected by global warming? ArchiMer
Mella-flores, D.; Mazard, S.; Humily, F.; Partensky, F.; Mahe, F.; Bariat, L.; Courties, C.; Marie, D.; Ras, J.; Mauriac, R.; Jeanthon, C.; Bendif, El Mahdi; Ostrowski, M.; Scanlan, D. J.; Garczarek, L..
Biological communities populating the Mediterranean Sea, which is situated at the northern boundary of the subtropics, are often claimed to be particularly affected by global warming. This is indicated, for instance, by the introduction of (sub) tropical species of fish or invertebrates that can displace local species. This raises the question of whether microbial communities are similarly affected, especially in the Levantine basin where sea surface temperatures have significantly risen over the last 25 years (0.50 +/- 0.11 degrees C in average per decade, P < 0.01). In this paper, the genetic diversity of the two most abundant members of the phytoplankton community, the picocyanobacteria Prochlorococcus and Synechococcus, was examined during two...

La qualité des eaux de l'étang de pisciculture et son contrôle [Water quality in fish pond and its control] Animal Physiology
Billard, R.; Marie, D..
La productivité des eaux dépend de quelques paramètres comme la température, l'oxygène dissous, le pH, la teneur en minéraux essentiels. Quelques-uns de ces paramètres sont mesurables et sont susceptibles d'aider à la prise de décisions en ce qui concerne l'oxygénation, la distribution d'amendement, d'engrais ou d'aliments. Ces méthodes sont cependant grossières et restent à améliorer. [Water productivity depends on parameters such as temperature, dissolved oxygen, pH and essential minerals. Some of them can be measured and may contribute to decide some interventions such as oxygenation, liming, fertilization or feed supply. These methods are however primitive and should be improved.]

Picoplankton diversity in the South-East Pacific Ocean from cultures ArchiMer
Le Gall, F.; Rigaut-jalabert, F.; Marie, D.; Garczarek, L.; Viprey, M.; Gobet, Angelique; Vaulot, D..
In late 2004, the BIOSOPE cruise sailed between the equatorial influenced waters off the Marquesas Islands and the nutrient enriched waters of the Chilean upwelling. Along the way, it explored the Southeast Pacific gyre centred around Easter Island, which is probably the most oligotrophic oceanic region on earth. During this cruise, we undertook a vigorous effort to isolate novel photosynthetic picoplanktonic eukaryotes. Two strategies were attempted on board: enrichment of filtered samples with culture medium and sorting of specific populations by flow cytometry based on size and chlorophyll fluorescence. Over 1900 pre-cultures were started and then further purified by flow cytometry, serial dilution or pipette isolation to yield a total of 212 strains....

Coral reefs are the most diverse habitats in the marine realm. Their productivity, structural complexity, and biodiversity critically depend on ecosystem services provided by corals that are threatened because of climate change effects-in particular, ocean warming and acidification. The coral holobiont is composed of the coral animal host, endosymbiotic dinoflagellates, associated viruses, bacteria, and other microeukaryotes. In particular, the mandatory photosymbiosis with microalgae of the family Symbiodiniaceae and its consequences on the evolution, physiology, and stress resilience of the coral holobiont have yet to be fully elucidated. The functioning of the holobiont as a whole is largely unknown, although bacteria and viruses are presumed to play...
