Genetic differentiation among the three greater horseshoe bats populations. a PCA plot of PC1 vs. PC2 from 21,945 SNPs for all 14 samples. Populations are colored according to genetic group assignment. b Ad-hoc statistics Î(K) based on STRUCTURE lnP(D) summarized over 10 replications for each K (assumed number of populations). c Population structure for Kâ=â2â4. Vertical lines indicate separate clusters, with cluster colors indicating various ancestries
