aAll specimens came from natural populations. Statistically significant differences (p < 0.001) were detected in the number of C-autosomes between Andean (16.54 + 1.29) and non-Andean (5.93 + 0.45) grouped samples.
bP, peridomiciliary; D, domiciliary; S, sylvatic.
cNumbers in brackets refer to the location of the populations in Figure 1
