FIGURE 4 in DNA analysis of a non-native lineage of Sinanodonta woodiana species complex (Bivalvia: Unionidae) from Middle Asia supports the Chinese origin of the European invaders

FIGURE 4. Median-joining network of the COI sequences of Sinanodonta cf. gibba (Benson in Cantor, 1842) (N = 53; list of additional sequences in Appendix 1). The red numbers near branches indicate the numbers of nucleotide substitutions between haplotypes. Size of circles corresponds to the number of available sequences for each haplotype (smallest circle = 1 sequence).
