The skull differences between two sexes based on 22 skull morphological indexes. A, E. cansus; B, M. aspalax; C, E. rothschildi; D, E. baileyi. The samples in black and white represent males and females, respectively. * represents highly significant difference (p < 0.05); ** represents significant difference (p < 0.01) and ns represents no significant difference (p > 0.05).
Skull differences of males among populations based on ANOVA and multiple comparison. A, CL, BL, CB, ZB, LLJ, LMP, GMB, OL, CH; B, LLC, LUC, OWU, BAB, BNB, OS, LDL, SFC. * represents highly significant difference (p < 0.05) and ** represents significant difference (p < 0.01).
Skull differences of females among populations based on ANOVA and multiple comparison. A, CL, BL, CB, ZB, LLJ, LMP, GMB, OL, LNB, CH; B, LDU, LAB, LLC, LUC, OWU, BAB, BNB, OS, SPC, LDL, SFC. * represents highly significant difference (p < 0.05) and ** represents significant difference (p < 0.01).
Skull indexes clustering. A, males; B, females.
Contribution proportion of the first ten principal components. A, male; B, female.
Contribution of variables to the first two principal components. A, male (variables to Dim-1); B, male (variables to Dim-2); C, female (variables to Dim-1); D, female (variables to Dim-2).
Correlations between variables and the first two principal components. A, male; B, female.
The box plots of zygomatic breadth among four zokor species. A, males; B, females.
