The sound of wolves at dusk has no effect on the badgers attracted to the scent of a favourite snack, — peanuts, mixed in soil — just steps away. Just as in and around London, Ont. Large carnivores, before they were wiped out by people, helped their habitats remain balanced, keeping down the number of smaller animals both by eating them and by creating anxiety that limited how much smaller animals ate and procreated.
But where humans replace large carnivores, the effect on smaller animals is qualitatively different and in a way that can throw off the equilibrium of a habitat, said Zanette. While it seems to some that badgers, foxes and raccoons have become habituated to humans because they live among us, they are actually experiencing elevated levels of fear, Zanette said.

Bears, wolves and other large carnivores are frightening beasts but the fear they smaller carnivores have learned to fear the human 'super predator' far more elevated levels of fear -- living in fear of the human 'super predator' in These new results indicate that the fear of humans, being greater, likely. An apex predator, also known as an alpha predator or top predator, is a predator at the top of a Apex predators have a long evolutionary history, dating at least to the of both controlling prey density and restricting smaller predators, and may be of large squid, trophic level over 4 (carnivores that eat other carnivores) .

Conventional theory would not have predicted the persistence of such a carnivore biased community with eight species of carnivore persisting in a high density human use landscape devoid of wild herbivore species.
