FIGURE A5-1. Results of the principal component analysis based on the skull shape, combined of S. araneus and S. tundrensis samples. A. Morphospace within PC1–2 with clear separation both species; B1. Skull shape (in ventral view) in a transformation frame on the negative end of PC1 that corresponding to S. tundrensis; B2. Skull shape (in a transformation frame on the positive end of PC1 that corresponding to S. araneus.
