Restoration of large carnivore populations, such as dingoes, is controversial as these animals can prey on livestock and threatened species. Developing an in-depth understanding of dingo dietary preferences across Australia’s bioclimatic zones may assist restoration proposals, especially if this helps to predict the types of impacts dingoes could exert on prey species and ecological processes such as bioturbation, herbivory and predation. Using 73 published and unpublished data sets, we examined bioclimatic variation in dingo diet across Australia, and focus here on the arid interior and temperate south-east of the continent. Dingoes consume at least 188, mostly mammalian, vertebrate species. Consumption of arthropods, birds and reptiles was highest in the arid and semi-arid regions, and lowest in the temperate south-east. Consumption of introduced rabbits was highest in the arid zone, and consumption of medium-sized mammals (0.5–6.9 kg) was highest in the temperate south-east. Dietary diversity was higher in the arid zone than in the temperate south-east. We use our results to describe dingo dietary patterns at the continental scale and discuss conservation and management implications.
