Abstract

Lay Summary Large carnivores protect ecosystems by frightening mesocarnivores, and “fearless” mesocarnivores wreak havoc where large carnivores are lost. Species may become naïve to potential threats (“tame” in Darwin’s words) when separated from predators, and we show that smaller “mesocarnivores” such as raccoons can be naïve to large carnivores where these top predators have been driven to local extinction. Naiveté in mesocarnivores may threaten biodiversity by leading to unchecked mesocarnivore foraging.Twitter: @JPSuraci
