Fig. 3: Spatiotemporal reconstruction of Nidirana.

a Ten geographical areas delineated for the genus Nidirana. Characters for geographical areas and dashed lines for barriers are corresponding to the information in Supplementary Table S2. b Ancestral distributions reconstructed by Dispersal-Extinction-Cladogenesis model. Areas with the highest probabilities at nodes are shown with the same characters in Fig. 3a. Within the N. adenopleura complex, populations are labelled with solid circles of different colors: N. mangveni (MV), the Poyang population (PY), N. guangdongensis (GD), and four populations of N. adenopleura: Taiwan (At), north (An), center (Ac), and west (Aw). c Dispersal events along branches through time. d Cladogenetic change events through time. e Development of East Asian Monsoon from Miocene with the fluctuations of fluvial mass accumulation rate representing level of precipitation and carbon isotopes representing level of temperature30,34,45.
