PCA showing the individual projections of Calomys sp., C. expulsus and C. tener in the two major axis (PC1 28.7%, PC2 12.3% of the variance). The wireframes illustrate shape differences between most different specimens: CE 09, CT 05, CT 02, and SP 11. Black circles: C. expulsus; Gray triangle: C. tener; Black square: Calomys sp. identified as C. expulsus; Gray square: Calomys sp. identified as C. tener; Gray triangle with black edge: specimen CT 02; Stars: mean shape for each species.
