Acoustic differentiation and behavioral response reveals cryptic species within Buergeria treefrogs (Anura, Rhacophoridae) from Taiwan
Fig 5
Principal component analysis and morphological differentiation between the Japanese and the Taiwanese clades.
The Japanese clade (Buergeria japonica) is abbreviated as JP and represented in blue; and the Taiwanese clade (Buergeria otai sp. nov.) is abbreviated as OT and represented in orange. These two clades differed significantly in PC2, which was consisted majorly by the size and shape of the head (F1,14 = 15.85, p = 0.001).
