* Statistically significant (P < 0.05)
Three comparisons for the AMOVA were made for both Chs and Lfy loci: (1) four geographic regions as defined by Lin et al. [35], (2) the eastern (E) and western (W) parts separated by the Central Mountain Range (CMR), and (3) the three geographic regions west of the CMR
