WitrynaInside the fence, red kangaroo and emu populations showed a 'typical' post-drought recovery. The data therefore suggest that, in some situations, dingoes may not simply limit red kangaroo and emu populations, but also regulate them. For this to occur, predation rate would need to be density dependent at low prey densities.
