Figure 2. Least-squares means for multivariate body size and size-corrected biometric variables in the different mitochondrial lineages examined. Only the characters most relevant for global biometric variation and group discrimination (after principle components analysis and canonical variates analysis, respectively; see Results) are presented. Error bars denote ± standard deviation. Females of each group are always presented first, denoted with a grey vertical bar, and males are in black. See Table 1 for group codes, Material and methods for variable abbreviations, and Figure 1 for symbols used to represent each lineage.
