Previously we reported the changes in the bioconvection pattern of Tetrahymena and Chlamydomonas, viewed from top, in response to the altered gravity during parabolic fight by an airplane. In top-view recordings, patterns from Tetrahymena were observed to decrease their size under hypergravity and disappeared under microgravity. The patterns from Chlamydomonas, on the other hand, showed little changes in their size under hypergravity, although the patterns were observed to be enhanced under hypergravity. The patterns by Chlamydomonas remained less changed under microgravity. These results were confirmed by the analyses on the side-view recordings of the bioconvection pattern of the same specimens. In Tetrahymena the number of the settling blob increased, corresponding to the decreasing pattern size under hypergravity. In Chlamydomonas, the settling blobs changed to the shape of a bottle with constricted neck under hypergravity, which may correspond to the enhanced (or sharpened) pattern in the top-view recordings. Interestingly, side-view recordings revealed that large population of the microorganisms swam preferentially upwards and accumulated at the top of the chamber under microgravity, which caused, especially in Tetrahymena, abrupt formation of the settling blobs at the onset of the hypergravity., 形態: カラー図版あり, 資料番号: AA0064297061},
