Figure 5.

Phylogenetic relationships as obtained from complete mitochondrial cytochrome b gene sequences (39 haplotypes), with branch lengths drawn according to those estimated by the NJ algorithm and by applying the TVM + I + Γ model of sequence evolution. Abbreviations refer to those listed in 1 and numbers on nodes indicate support values for internal branches (first: NJ, second: MP, third: ML) based on 1,000 bootstrap replicates (NJ, MP) or 10,000 quartet puzzling steps (ML).
