Fig. 2: Phylogeny and PCA relationship for genus Nidirana based on SNPs data.

a Phylogeny of the genus Nidirana, using maximum likelihood based on SNPs data. Values of bootstrap supports (BS) larger than 90 are shown. Within the N. adenopleura complex, different populations are labelled with solid circles of different colors: N. mangveni, the Poyang population, N. guangdongensis, and four populations of N. adenopleura: Taiwan, north, center, and west. b Two-dimensional PCA plot for genetic variation in the genus Nidirana.
