Figure 3 in Genetic and morphological evidence for two species of Leucocarbo shag (Aves, Pelecaniformes, Phalacrocoracidae) from southern South Island of New Zealand

Figure 3. Parsimony-based network reconstruction of Chatham Island (green), Otago (blue), and Foveaux (red) shags. Haplotypes are represented by circles. The number of sequences within each haplotype is indicated by the size of the circles and shown by the numbers. Two haplotypes are connected by a line if they are separated by one mutation; each additional mutation is indicated by a small black dot. Light colouring refers to extinct (premodern, i.e. pre-1890 AD) haplotypes, whereas dark colouring refers to extant (modern, i.e. post-1890 AD) haplotypes.
