[B-PT24_29AM2] Evolution of Chemosynthetic Ecosystem in Earth History

Tue. Apr 29, 2014 11:00 AM - 12:30 PM 213 (2F)

Convener:*Robert Jenkins(School of Natural System, College of Science and Engineering, Kanazawa University), Hiromi WATANABE(Japan Agency for Marine-Earth Science and Technology), Takami Nobuhara(Science Education (Geology), Faculty of Education, Shizuoka University), Ryuichi Majima(Faculty of Education and Human Sciences, Yokohama National University), Chair:Hiromi WATANABE(Japan Agency for Marine-Earth Science and Technology), Robert Jenkins(School of Natural System, College of Science and Engineering, Kanazawa University)

Chemosynthetic communities have changed in their taxonomic composition and spatial distribution through the Earth history, but the causes and backgrounds remain to be unclear. Topics and information in various studies will be exchanged between geology, paleontology, geochemistry, and biology.? We also hope to raise some seeds of co-works on evolutionary study on chemosynthetic ecosystem.
