those that received no toad training, ultimately this reintroduction population rapidly went extinct because of dingo predation. Subsequently, research comparing antipredator behaviours of quolls from Astell Island and mainland Queensland determined that quolls conserved on this island had lost their ability to recognise and avoid both dingo and cats, predators they have co-evolved with on mainland Australia for at least 3500 and 150 years respectively. This study suggests that animals conserved in complete isolation from predators can rapidly lose evolved antipredator behaviours, in this case in only 13 generations, when they are no longer maintained via natural selection. In Aboriginal language and culture The Northern Quoll is known as njanjma in the Indigenous Kundjeyhmi, Kundedjnjenghmi and Mayali languages, djabbo in Kunwinjku, and wijingarri in Wunambal. The Kunwinjku people of Western Arnhem Land (Northern Territory) regard djabbo as "good tucker". References Cited references General references Braithwaite, R.W. & R.J.
