Abstract

In old predator-prey models, prey were not able to respond to the presence of the predator. New models which included this feature showed that non-lethal effects of the predator might play a huge role in a predator-prey interaction. These non-lethal effects on the prey lead to changes in behavior which induce cascading effects that might influence other parts of the ecosystem. Empirical data from Yellowstone National Park showed that these non-lethal effects play a major role in the interaction between wolves and elk and shape the ecosystem. This concept is called the ecology of fear. It is however unknown how common this ecology of fear. By looking at the definition of the ecology of fear and see if other predator-induced changes in behavior match these definitions I can conclude that the ecology of fear is widespread across a wide variety of predator-prey interactions and that this might influence our understanding of ecosystem conservation.
