Postural adaptation during dauer exit. a Schematic of a worm skeleton. For each skeleton, we calculate a vector of 24 intersegment angles that describe the worm’s posture. b Heatmap of the relative occurrences of 120 postures during dauer exit on a food source as quantified from n = 3 experiments. Color indicates whether a posture is over or underrepresented at that time point relative to all time points. The upper bars indicate three meta posture groups, each comprising several postures, and their allocation within the heatmap. Meta postures were obtained by a second k-means clustering with k = 3 of all postures from all experimental conditions. c The three meta postures that were calculated across all conditions. All postures of one group are depicted in gray and one example posture is shown in color. d Distribution of all intersegment angles, calculated as shown in a. The dauer-specific meta posture p1 is compared to the two other meta postures p2 and p3. p1 contains 46 postures, p2 and p3 contain 28 and 46 postures, respectively. e Relative occurrence of the meta posture p1 during dauer exit, normalized to all time points of the depicted experimental condition. Each dot represents one experiment of n = 3 experiments. f Turn frequency during dauer exit, quantified with a custom random forest classifier (see Materials and Methods). Depicted is the mean, error bars are SEM
