Metrics for describing pattern variation. (A) Entropies for patterns of individual wild-type fish measured along the DV axis (stripe entropy, E_DV) and AP axis (bar entropy, E_AP) with each point representing the mean entropies across transects within a single fish. Species symbols correspond to Fig. 1. Dashed line denotes equal stripe and bar entropy. The plot reveals broad pattern types (e.g. stripes above dashed line, bars right of dashed line) and species-differences in pattern space. (B) Pattern strength (σ) and orientation (Ω) also distinguished among pattern types (e.g. bars at right, stripes at left). Dashed line denotes patterns with similar horizontal and vertical contributions. (C) Species patterns are more dispersed in the morphospace defined by stripe variation (V_DV) and bar variation (V_AP) compared to the other morphospaces. Dashed line denotes equal stripe and bar pattern. (D) Species are best delimited in a higher dimensional space derived from all six pattern metrics. Shown are the species plotted against the first two canonicals resulting from a discriminant analysis using all six pattern metrics. Loadings of metrics along the first two canonicals are shown.
