...Monika Fejtek; Kenneth Souza; Anton Neff; Richard Wassersug ABSTRACT We examined the respiratory behaviours and swimming kinematics of Xenopus laevis tadpoles hatched in microgravity (Space Shuttle), simulated microgravity (clinostat) and hypergravity (3 g centrifuge). All observations were made...

...Ruth Hemmersbach; Regine Voormanns; Donat-P. Häder ABSTRACT Behavioural responses to different accelerations below 1 g and up to 5 g were investigated in Paramecium biaurelia by using a centrifuge microscope on Earth and in space during a recent space flight. Increased stimulation (hypergravity...

...Richard Bräucker; Sigrun Machemer-Röhnisch; Hans Machemer ABSTRACT The swimming behaviours of two species of ciliates characterized by different mechanosensory and ciliary motor properties were investigated under hypergravity up to 5.4 g . The experiments were designed to examine large numbers...

...Mayumi Ooya; Yoshihiro Mogami; Akemi Izumi-Kurotani; Shoji A. Baba ABSTRACT The swimming behaviour of Paramecium was analyzed under natural and experimental hypergravity conditions. Paramecium that swam upwards (in the opposite direction to the gravitational force) along a straight path (straight...
