Population genomic structure analysis using Admixture based on 747 putatively adaptive SNPs for southern Australian common dolphins (D. delphis), labelled by sampling site. The results depict levels of admixture for each individual sample, grouping them into five adaptive genomic clusters (K = 5). Each sample is represented by one vertical line and is colour-coded based on the membership probability to one of the identified locally adapted populations. *Acronyms as in Fig. 1
