Figure 1 in First use of acoustic calls to distinguish cryptic members of a fish species complex

Figure 1. Background shading indicates the geographical distribution of the three populations (Liu et al., 2014) from the Dascyllus aruanus complex. A, in each geographical area, dots correspond to sampling locations. B, scatterplot of principal component PC1 versus PC2, performed with individual mean values of the six acoustic properties of calls corresponding to the signal jump for the three suggested species: D. abudafur (blue ●), D. aruanus (turquoise +) and D. emamo (pink▲). Ellipses correspond to 90% of the observations, dots correspond to the ellipse centra.
