Figure 2.

Quantification and presentation of different aspects of the swimming patterns in wild-type A. brasilense. (A) The distribution of turning angles during swimming in wild-type A. brasilense is shown. (B) i) A run-reverse swimming pattern as seen in wild-type A. brasilense is shown. (C) i) A run-reverse-flick-like event as seen during swimming of wild-type A. brasilense is shown. (D) The distribution of events with transient pause and reversals as classified based on turning angle threshold. (B, C, and E) ii) The instantaneous speed, iii) angular velocity, and iv) direction of travel for the same trajectory are shown in separate horizontal panels. (E) A typical trajectory with two consecutive transient pauses is shown. (F) A scatter plot and kernel density plot showing the correlation of abrupt turns/s versus reversals/s is shown. (G) A scatter plot and kernel density plot showing the correlation of transient pauses/s versus reversals/s. The yellow color in (B) and (C) represents the frames involved in the turning event, whereas the red dot represents a transient pause. The blue shading in the right panels of (F) and (G) indicate density of the events, with darker blue meaning more events. To see this figure in color, go online.
