Do introduced predators compete with native carnivores?

The spotted-tailed quoll (Dasyurus maculatus) is a medium-sized marsupial carnivore that has declined in abundance and distribution since European settlement in Australia, and is now listed federally as an endangered species. Introduced predators are thought to have contributed to this decline. Foxes and feral cats occupy a similar dietary niche to that of quolls, and may be directly aggressive to them. The impacts of dingoes and other wild dogs are also of interest, as they have the potential to compete with quolls, but may also suppress populations of cats and foxes. Here I report on the extent of overlap in resource use between sympatric populations of quolls and eutherian predators. The study was conducted in Marengo and Chaelundi State Forests, north-eastern New South Wales, between January 2003 and October 2004.
