Inferred genetic structure of Chinese pangolin subpopulations of Guangdong Province according to (a)ADMIXTURE analysis when K = 2, (b, c) PCA, and (d) DensiTree showing 100,000 phylogenetic tree topologies inferred from whole mitochondrial genome sequences using BEAST. In (a), codes above and below the plot refer to individual and subpopulation, respectively. *denotes the optimal K value. In (a), (b) and (c), different subpopulations are indicated with different colours. In (d), blue line represents the most well-represented tree topology, followed by the red topology and finally the green. Labels on nodes indicate the posterior probabilities of the Maximum Clade Credibility Tree
