Figure 6.

PCA based on sections of identity by descent for all wild mice genotyped with the MegaMUGA SNP array, with an enlargement below of the distribution of New Zealand wild mouse samples. New Zealand locations are shown as circles, native-range samples are shown as triangles (in the lower plot). Owing to crowding we amalgamated some sampling locations for ease of display: Canterbury = (Christchurch, Ashburton, Mawaro, Temuka, Timaru), Central NI = (Hamilton, Omori, Taranaki, Pourewa Is.) and Southern SI = (Matukituki, Hollyford, Eglinton, Grebe, Pig Creek, Tairoa).
