FIGURE 2. Topology of phylogenetic relationships among specimens of O. atricapillus and O. beecheyi from California and the Baja California Peninsula based on the complete Cyt b gene Callospermophilus madrensis, C. lateralis, and C. saturatus was used as outgroup. The main topology recovered from all the analyses shows that O. atricapillus (haplotypes 29 to 32) and O. beecheyi (haplotypes 1-28) are monophyletic. All the phylogenetic analyses revealed three major clades. The first clade groups all specimens from lowlands across California and Baja California Peninsula (Clade A, Southern Clade); the second one contains specimens from the California highlands in El Dorado Natural Forest (Clade B, Northern Clade); and the third contains specimens from the California highlands in Yosemite (Clade C, Central Clade). The nodal support values in each of the main nodes are in order: NJ bootstrap, maximum-likelihood bootstrap, Bayesian posterior probabilities (x100), and maximumparsimony bootstrap. At the tip of each branch is the number of the haplotype.
