TABLE 7. Results of principal components analysis of craniodental measurements of young specimens (age class 2, n = 199) of A. spegazzinii Thomas (n = 40) and all its associated nominal forms: A. alterus Thomas (n = 18), A. leucolimnaeus Cabrera (n = 8), and A. tucumanensis J. A. Allen (n = 101). Asterisk indicates significative principal components after the Broken-stick test.| Variable | PC1 | Pearson correlation PC2 | PC3 |
