Fig. 164. Three alternative phylogeographic hypotheses. A: Primary Diversification: reciprocally monophyletic and sister clades bounded by a river that imposed itself on an existing species range. B: Secondary Contact: reciprocally monophyletic, but nonsister clades, bounded by a river that served as the secondary meeting point of clades that evolved elsewhere. C: Dispersal: paraphyletic relationship of right bank haplotypes relative to left bank ones due to one episode of cross­river transfer. See text for further explanation.
