From: Natural clines and human management impact the genetic structure of Algerian honey bee populations
PCA and Admixture analyses restricted to the Algerian population and geographic distribution of samples. a PCA plot of the top two principal components (PC1 and PC2), over the Algerian honey bee population. Individual samples are coloured in accordance with their main ADMIXTURE component at K = 2, mark transparency indicating the most admixed samples and mark shapes denoting the subspecies (squares for A. m. intermissa; triangles for A. m. sahariensis). b Plot of ADMIXTURE results at K = 2 over the Algerian honey bee population, ordered by longitude. Each bar represents an individual sample and the 16 A. m. sahariensis samples are identified. c Distribution of sampling sites, using the same graphical code as in a, with admixture proportions averaged over all individuals sampled at a given site. The mark size is proportional to the number of samples
