Figure 1. Expected range maps for (a) resident and (b) Bigg's killer whales, including locations of samples used for mitogenome analysis (figure 5a, resident n = 106, Bigg's n = 93) [15]. Distribution ranges have been inferred based on published identifications of individuals that are identified by ecotype [48–53]. Sample distributions cover the known ranges of both ecotypes, with the exception of residents of Oregon and northern California, and both ecotypes off northern Japan (Hokkaido) in the western Pacific [48,54]. Sample maps for microsatellite data are in electronic supplementary material, figure S2.
