The Amazon River system as an ecological barrier driving genetic differentiation of the pink dolphin (Inia geoffrensis)

Abstract

FIGURE 9. Cladogram of mtCOI showing proportional differences between individuals of Pseudodiaptomus nansei sp. nov. from Hirakubo-gawa River and P. inopinus Burckhardt, 1913 from Tsuri-kawa River. Numbers at branch points are bootstrap values. The cladogram is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the tree. Pseudodiaptomus ishigakiensis Nishida, 1985 collected from Kabira Bay, Ishigaki Island, was used as the outgroup. Specimen numbers correspond to those in Table 2.
