Three-Dimensional Analysis of the Swimming Behavior of Daphnia magna Exposed to Nanosized Titanium Dioxide

Ensemble mean swimming velocities.
of Daphnia magna (A) at times after application and (B) in relation to corresponding body lengths. Error bars are omitted for the sake of clarity. Please refer to Table S2 for standard deviations. Velocities significantly different (p<0.05) from the control are surrounded by circles. Please note that only velocities of similar body lengths (1.22 mm for C, 1.44 mm for T5 and 1.23 mm for T20) had been tested with respect to significant differences. Linear regression for C with dv/dL = 4.4 1/s (black line, r2 = 0.87) and for T1 with dv/dL = 1.2 1/s (grey line, r2 = 0.3).
