WebThe global distribution of this clade makes it an excellent group to test hypotheses regarding the processes underlying tropical intercontinental disjunctions. More specifically, it allows us to test whether current distribution patterns resulted from recent transoceanic long-distance dispersal or ancient vicariance after boreotropical migration.
