• Responses of bioconvection pattern to altered gravity

抄録

We proposed a research which aims to reveal the possibility for gravity to develop new functions of the biological systems through the collective interactions between the components of the systems. Bioconvection of the aquatic microorganisms has been focused as a research tool for the proposal. In this paper, responses were investigated of the bioconvection pattern of Tetrahymena and Chlamydomonas to the altered gravity during parabolic fight of an airplane. In Tetrahymena, patterns were observed to increase their size under hypergravity and disappeared under microgravity. In Chlamydomonas, changes in the pattern size under hypergravity was less clear, although the patterns were observed to be enhanced under hypergravity. The patterns by Chlamydomonas remained less changed under microgravity. These differences in the response between organisms may be informative for the investigations for the development of the new research fields in space and gravitational biology.
