Using this contextual paleogeographic information (paleogeographic time series is shown in panels A-D) the authors of this study[REF] proposed a null-hypothesis that assumes no spatial structure and two alternative hypothesis involving dispersal and other biogeographic constraints (hypothesis are shown in panels E-G, listed as SMO, SM1, and SM2).
The evolutionary history and relations among different poison frog species is reconstructed using phylogenetic trees derived from molecular data.
