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., 資料番号: AA0063349096}, pages = {335--338}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {変動重力に対する生物対流パターンの応答}, year = {2007} }
