Fig. 2

Population genetic structure of Rediviva longimanus according to principal component analysis (PCA). (a) PCA, performed in PCADAPT, suggested that three principal components explained most of the population genetic structure and revealed a clear separation into four population clusters. (b) Analysing more than three components did not contribute to disentangle further population genetic structure and revealed additional variance within rather than between clusters
