Fig. 6 in A New Species Of Mudskipper, Boleophthalmus Poti (Teleostei: Gobiidae: Oxudercinae) From The Gulf Of Papua, Papua New Guinea, And A Key To The Genus

Fig. 6. Multivariate morphological analyses of the three species of Boleophthalmus without notched dentary teeth, supporting the separation of the examined specimens in 3 morphologically distinct groups. A: PCO scatter plot of meristic characters, after logarithmic transformation. The two coordinate axes Coord 1 and Coord 2 explained the highest percentage of total variance (in parentheses); closed lined (convex hulls) delimit clusters of specimens of the same species. B: PCA distance biplot of morphometric characters after Darroch & Mosimann transformation (1985). The two principal component axes PC1 and PC2 explained the highest percentage of total variance (in parentheses); closed lines (convex hulls) delimit clusters of specimens of the same species; the variables are projected onto the scattergram as vectors, graphically visualising their PCA loadings, or the degree they enter into the principal components. PLVL separates caer from bird and poti, while D1BL separates bird from caer and poti. bird = B. birdsongi (n = 11); caer = B. caeruleomaculatus (n = 4); poti = B. poti (n = 10). See Tables 3, 4 for the dataset.
