Figure S3 in Multi-locus analyses reveal four giraffe species instead of one

Figure S3. Additional Structure and PCA analyses. Related to Figure 3. A) Structure analysis for all subspecies for K=2 to K=6. K=4 has the highest delta K and from K=5 increasing admixtures is evident. B) A separate Structure analysis for the subspecies of the northern giraffe reveals evidence for additional cluster of West African (WA) and Nubian (former Rothschild's, MF) giraffe. However, in this data set haplotypes sharing with other subspecies is evident and these are not distinct in other analyses. C) Southern giraffe do not show additional clustering when analyzed separately. This is in contrast the the clear separation of the subspecies by mtDNA sequences. Abbreviations for the geographic origin are explained in Table S1. D) PCAs of giraffe haplotypes with grouping according to traditional nine subspecies classification 1 - G. c. angolensis, 2 - G. c. antiquorum, 3 – G. c. thornicrofti, 4 - G. c.
