Principal component analysis (PCA) of nine loci under natural selection.

<p>Ordination of all 173 individuals based on nine AFLP loci detected by the program BayeScan. Each circle represents a single genotype and its size corresponds to the number of identical genotypes. The circles are colored according to two sampling regions (blue: Bukit Duabelas, BJ/BR/BO individuals; red: Harapan, HJ/HR/HO individuals). The nine loci exceeding a threshold for decisive evidence for selection (with probability “<i>P</i>” ≥ 0.99) are listed including their respective restriction sites (RS); loci concordantly depicted by the program Mcheza are marked by an asterisk.
