Fig. 5: Maps of admixture proportions for M. guttatus conStruct spatial and non-spatial analyses using K-values between 2 and 4.

Pies show mean admixture proportions across individuals from a given sampling site. Panels a–f show populations from the Sierra Nevada with colours to match Fig. 3, with the scale bar representing 100 km. Panels g–l show range-wide populations, with green southern, orange coastal, purple northern, blue inland and teal central, with the scale bar representing 500 km.
