Though the Tasmanian population grew in numbers after it was isolated, it was stuck with a low level of genetic variation and passed this deficiency on to modern devil populations.

Founder populations are essential to the study of island biogeography and island ecology. A natural "blank slate" is not easily found, but a classic series of studies on founder population effects was done following the catastrophic 1883 eruption of Krakatoa, which erased all life on the island. Another continuing study has been following the biocolonization of Surtsey, Iceland, a new volcanic island that erupted offshore between 1963 and 1967.
