Rarity of a top predator triggers continent-wide collapse of mammal prey: dingoes and marsupials in Australia

Johnson, Christopher; Isaac, Joanne; Fisher, Diana


Top predators in terrestrial ecosystems may limit populations of smaller predators that could otherwise become over abundant and cause declines and extinctions of some prey. It is therefore possible that top predators indirectly protect many species of prey from excessive predation. This effect has been demonstrated in some small-scale studies, but it is not known how general or important it is in maintaining prey biodiversity. During the last 150 years, Australia has suffered the world's...[Show more]
