^aSequence diversity (Nei 1987) and divergence (Nei 1987) for each dataset were determined using DNAsp ver. 5 (Librado & Rozas 2009). π = the average number of nucleotide differences per site between two sequences, D_xy = the average number of nucleotide substitutions per site between populations, D_a = the number of net nucleotide substitutions per site between populations. π, D_xy, and D_a values were converted to percentages for comparative purposes.

^bThe shape of the gamma distribution which indicate the pattern of among-site rate heterogeneity for all gene datasets were inferred by with jModeltest (Posada 2008).
