Fig. 7. (A) Box-and-whisker diagram of the adhesion force of single adhesive droplets in the tentacle-shaped trichomes of Roridula gorgonias, measured on different surfaces. The ends of the boxes define the 25th and 75th percentiles, with a line at the median and error bars defining the 10th and 19th percentiles. Arrows point to areas of substrates where force was measured. (B) Statistical differences between surfaces (Kruskal–Wallis one-way ANOVA on ranks, H_5,119=25.317, P0.001 and Tukey test, P<0.05).
