Fig. 4: Population structure analyses for the global (ALL) dataset.
From: Tracing the introduction of the invasive common myna using population genomics
A PC1 vs PC2 for the ALL dataset, number of individuals subsampled to n = 20 per introduced populations, based on 5572 SNPs. Colour and shapes of points represent sample locations. B PC1 vs PC2 for the ALL dataset with only populations that clustered closely with New Zealand. This includes NZ: Other, NZ: Napier, Fiji, AUS: Melbourne, AUS: Sydney and IND: Maharashtra subpopulation A. In (A) and (B), axes are labelled with the variance explained. C Population structure estimated by sNMF analysis, using K = 8. Three-letter codes are abbreviations of population names, as shown in the legend of the PCA plots. The cluster number refers to the genetic clusters described in text as shown by the PCA and the sNMF population structure plot.
