Les régions polaires sont particulièrement touchées par les changements climatiques, ce qui a profondes conséquences sur le développement du phytoplancton et le fonctionnement de la pompe biologique. La structure des communautés planctoniques et les propriétés spécifiques aux espèces influencent l'export de la matière organique et biominérale. Cette thèse a pour but (1) de déterminer les facteurs contrôlant la structure et le développement des communautés de diatomées dans les régions polaires, (2) d'évaluer l'influence de la diversité des espèces sur la composition de la matière particulaire, et (3) de comprendre les modes de mortalité et d'export des diatomées dans l'océan profond. Ces travaux reposent sur l'étude de deux régions subpolai...
