Le réchauffement climatique conduit à une diminution drastique de l’étendue et de l’épaisseur de la banquise entrainant un allongement et une intensification du bloom phytoplanctonique Arctique. L’augmentation de la production primaire pourrait modifier le fonctionnement de cet écosystème ainsi que les communautés bactériennes (CB) impliquées dans la dégradation de la matière organique (MO). Les objectifs de cette thèse étaient (1) de décrire la dynamique spatiale et temporelle in situ des CB lors du développement du bloom ; et (2) d’identifier expérimentalement les acteurs bactériens responsable de la dégradation de la MO excrétée par des microalgues arctiques. Les résultats montrent une forte réactivité des CB en réponse au bloom lors du ...
