The elevations and samples sizes (n) are shown in parentheses below the sample site abbreviations. For full names of sample sites, see Methods. The shading defines major mountain ranges, the black line defines the Santa Ana River, and the dashed lines encloses the possible zone of AKR/DKR sympatry, as defined by Sullivan and Best (1997).
