Results of PCA, and clustering by DAPC and STRUCTURE of 589-locus SNP dataset, comparing dusk/dawn endophagic and exophagic Nyssorhynchus darlingi. a PCA of dusk samples (red and blue dots) and dawn samples (purple and orange dots) from Granada. b DAPC ordination of all samples in the four genetic clusters (1–4) in two axes; bottom right box: number of PCs retained (n = 23). c Bayesian information criterion (BIC) to estimate the appropriate number of genetic clusters, which is the lowest BIC value. d STRUCTURE result: each column represents an individual and colors reflect genetic clusters assignment (best K = 2)
