What impact do cane toads have on Quolls?

Cane toads have had a major impact on quoll populations in Queensland and the Northern Territory. Quolls are carnivores, and feed on birds, reptiles, arthropods and mammals up to the size of a possum. Habitat loss has resulted in fewer of these species and thus a reduced food source for the quolls, so they have resorted to eating cane toads. Spotted-tail and Northern Quolls are both being killed off as a result of eating the Cane Toad, which is poisonous.
