Table 4 Percentage of correctly classified specimens by cross-validation test in discriminant function analysis (DFA). Significant differences are represented by asterisks, i.e., ***p < 0.0001 (permutation 10,000 rounds in MorphoJ). Numbers in brackets represent the number of correctly classified over the total number of specimens
