Figure 5 in Morphology of the Podarcis wall lizards (Squamata: Lacertidae) from the Iberian Peninsula and North Africa: patterns of variation in a putative cryptic species complex

Figure 5. Scatter plots of individuals scores (small symbols) and group means (big symbols) of the first three principal components of variation in continuous pholidotic traits for the mitochondrial lineages examined, considering males (top) and females (bottom) separately. The most highly (+, positively; -, negatively) contributing variables (Table 4) are indicated next to each axis. See Table 1 for group codes and Material and methods for variable abbreviations.
