Figure 5. The relationship between relative tail break distance and relative hind leg length for P. latiscutatus from A) Kozu and B) Mikura, where E. quadrivirgata is present, as well as from C) Miyake and D) Hachijo-Kojima, where E. quadrivirgata is absent. This shape represents the natural selection worked on relative hind leg. The solid and dashed lines indicate the median and the 95% Bayesian confidence intervals, respectively, in the posterior distribution obtained from Markov chain Monte Carlo simulations. Each point represents individual measurement values.
