Additional file 6 of Invasive patterns of Biomphalaria straminea revealed by genetic mapping in the Greater Bay Area, China

Supplementary material 6. Phylogenetic tree of COI gene among Biomphalaria. The tree was constructed by using the Maximum Likelihood method based on the Jones-Taylor-Thornton (JTT) model. The relative values (%) on branches are based on 1000 bootstrap resamplings. Planorbella trivolvis was used to form the outgroup. Biomphalaria straminea identified in the present study were shown in the square frame.
