| Outline of Final Research Achievements |
In order to resolve dynamic movement of deep-sea organisms in dynamics of the marine ecosystem, we studied, by genetic and ecological analyses, 1) a dispersal ability of deep-sea Bathymodiolus mussels, 2) genetic transition in Benthomodiolus geikotsucola in the whalebone-associated biological community, and 3) a dispersal ability of Adipicola pacifica in the whalebone-associated biological community. We showed high dispersal abilities of Bathymodiolus mussels and A. pacifica to exploit patchy and ephemeral habitats such as deep-sea vents and seeps and organic falls. We also showed no annual change between 1993 and 2005 in the genetic structure of B. geikotsucola.
