深海化学合成群集の生態系モデル

摘要

Using observational data collected at the North-Iheya field in Okinawa trough, we developed a food web model that includes four main members (Paralomis sp., Shinkaia crosneri, Alvinocaris longirostris, Bathymodiolus) of a chemosynthetic-community of a hydrothermal vent field. Using this model, we showed that a newly formed hydrothermal source can reduce the size of Batymodiolus mussel beds around it. Our method will be a standard framework to integrate observational data into modelling and to predict the population dynamics of hydrothermal vent communities.
