Table 1: Summary statistics of polymorphisms for the nine markers used in this study.
N is the number of sequences obtained (with numbers in parentheses referring to the sequences obtained from this study, obtained from previous studies and downloaded from Genbank); L is the length of the sequences in bp; S is the number of polymorphic segregating sites; h / a: h is the number of corresponding haplotypes for mitochondrial markers, and a is the number of alleles for nuclear markers; hd is the haplotype diversity and π is the nucleotide diversity. Due to the presence of ambiguities in the sequence for CR, two haplotype phases were considered here.
