Patterns of morphological variation in the Schlegel’s Japanese gecko (Gekko japonicus) across populations in China, Japan, and Korea

Table 2 Multivariate analyses of morphological data of Gekko japonicus from 11 populations. Component score coefficient matrix from the principal component analysis and standardized canonical discriminant function coefficients from the canonical variate analysis on the snout-vent length standardized data after log₁₀-transformation are presented. Only the components are shown, of which either have Eigenvalue (EV) greater than 1 or explained more than 10% of total variation
