Greater agility increases probability of survival in the endangered northern quoll.

Introduced predators combined with habitat loss and modification are threatening biodiversity worldwide, particularly the 'critical weight range' (CWR) mammals of Australia. In order to mitigate the impacts of invasive predators on native species in different landscapes, we must understand how the prey's morphology and performance determine their survival. Here, we evaluated how phenotypic traits related to escape performance predict the probability of survival for an endangered CWR mammal, the northern quoll ().
