Results of PCA, and clustering by DAPC and STRUCTURE of 944-locus SNP dataset, comparing endophagic and exophagic Nyssorhynchus darlingi. a PCA of outdoor samples (red and yellow dots) and indoor samples (blue and green dots) from Granada and Remansinho. b DAPC ordination of all samples in the three genetic clusters (1–3) in two axes; top right box: number of PCs retained (n = 28). c Bayesian information criterion (BIC) to estimate the appropriate number of genetic clusters, which is the lowest BIC value. d Results of STRUCTURE analysis: each column represents an individual and colors reflect genetic clusters assignment (K = 2 and K = 3)
