FIGURE 4. Individual specimen scores based on log-transformed values of 20 cranial measurements, projected onto the first and second principal components extracted from analysis of young specimens (age classes 2 and 3, n = 74) of Phyllotis nogalaris and 4 forms of P. tucumanus in Northwestern Argentina: P. nogalaris (white squares), P. tucumanus s.s. (black squares), P. tucumanus form 2 (white diamonds), P. tucumanus form 3 (white triangles), and P. tucumanus form 4 (white circles). Character loadings and percentage of variance explained by each of three PCs in Table 3
