Fig. 4
Duration of looping behavior (in s) of a, b, c, d H. incongruens and a N. monacha shown during 20 s long µg periods achieved during a parabolic flights (n = 12, except for Ps 8–31 in H. incongruens: n = 6), b, c clinorotation (nb = 10, nc = 7), and d a TEXUS sounding rocket flight (n = 10). Dotted trendlines (…) are fitted through the data points of all µg periods achieved per method, dashed trendlines (– – –) through the data points of the parabolic flight µg intervals in functional darkness (IR illumination). Mean value ± SEM
