Effects of bath temperature on spontaneous navigation. A Sketch defining three kinematic parameters. δtn is the time elapsed between bout n and bout n+1, known as the interbout interval. The displacement dn is the distance traveled during bout n (in mm), while δθn represents the reorientation angle. A small value around 0 corresponds essentially to a forward swim, while a large positive value (resp. negative) corresponds to a left (resp. right) turn. Per-batch averaged distributions of interbout intervals (B), displacements (C) and turn angles (D) for each tested temperatures. Vertical dotted lines are the means of the distributions, shaded areas are standard errors of the mean (s.e.m.). The gray area in D marks the forward events versus the turn events. EH Boxplots of selected parameters. Each dot corresponds to a batch of 10 fish, the box spans the 25th to the 75th percentiles, the horizontal line is the median, red crosses are outliers. Significance given only for neighboring boxes (Kruskal-Wallis test, no star indicates p>0.05,p<0.05,p<0.01,p<0.001). E Fraction of turns, referred to as the turning probability, defined as the ratio of turn bouts over the total number of bouts. F Means of the interbout intervals. G Means of the displacements. H Means of the absolute reorientation amplitude of turning bouts
