[B-CG05] Diversity and ecology of marine protists -from past to present

Fri. May 26, 2023 10:45 AM - 12:00 PM Exhibition Hall Special Setting (3) (Exhibition Hall 8, Makuhari Messe)

convener:Rie Hori, S.(Department of Earth Science, Faculty of Science, Ehime University), Yasuhide Nakamura(Estuary Research Center, Shimane University), Tristan Biard(UMR8187), Chairperson:Yasuhide Nakamura(Estuary Research Center, Shimane University), Rie Hori, S.(Department of Earth Science, Faculty of Science, Ehime University), Tristan Biard(UMR8187)

Protists emerged on Earth during the Precambrian era and have evolved along Geologic time. Recent molecular analyses and culturing experiments on living marine protists make remarkable progress and give us new findings, whereas the integration of the knowledge from these biological studies and that of earth sciences is indispensable as the next step. We, therefore, propose a session with a view to integrating the information from biological and paleontological approaches. We welcome a wide variety of presentations, from paleontological studies on fossils to biological studies on living protists.
