Threatened species indicate hot-spots of top-down regulation
The introduction of alien mesopredators and herbivores has been implicated as the main driver of mammalian extinction in Australia. Recent studies suggest that the devastating effects of invasive species are mitigated by top-order predators. The survival of many threatened species may therefore depe...

The introduction of alien mesopredators and herbivores has been implicated as the main driver of mammalian extinction in Australia.

Australia’s top predator, the dingo (Canis lupus dingo), has been intensively persecuted across the continent and it is extremely rare to find dingo populations that are not being subjected to lethal control.
