“I have taken pains to verify this assertion, and have found it true that frogs, toads, and newts are absent from most oceanic islands”—thus states Charles Darwin in his well-known work “On the Origin of Species.” For a long time, this observation by the famous naturalist also held true for the Galápagos Islands, which are inextricably linked to his name. “This only changed with the arrival of Fowler’s snouted treefrog Scinax quinquefasciatus on the archipelago in 1997 or 1998,” explains Dr. habil. Raffael Ernst of the Senckenberg Natural History Collections in Dresden, and he continues, “In our study, we examined the interactions of this newcomer with the local, primarily endemic fauna on Galápagos.”
