Phylogenetic and haplotype network analysis of COI data for C. curruca and the origin of study material A neighbor-joining tree, values on the branches shows bootstrap values and, an asterisk indicates Iranian COI sequences from GenBank B distribution range and collection sites for the samples included in the study. Approximate presumed breeding ranges of C. curruca taxa, modified from the map by Abdilzadeh et al. 2023; sampling sites are indicated by red triangles and GenBank sequences of C. c. halimodendri by a red star C haplotype network, where colors indicate the origin of the haplotypes (Orange: western population; Green: eastern populations) and the number of bars at each branch indicates the number of mutations.
