Prey naïveté hypothesis is a theory that suggests that native prey often struggle to recognize or avoid an introduced predator because they lack a coevolutionary history with it. Prey naïveté is believed to intensify the effects of non-native predators, which can contribute significantly to the risks of extinction and endangerment of prey ...
Predators can announce their presence through signals or predator cues. P. milvina use chemotactile predator cues like silk, faeces, and other excreta in order to determine when a predator is nearby. They are then able to respond to the amount of predation risk based on these cues. When visual or chemotactile predator cues are not present, P ...
Once a predator has found its prey it will not always attempt to chase or eat it. Prey have other ways of deterring predators from eating them besides avoiding detection. Aposematic plants and animals may have conspicuous coloration such that potential consumers such as a herbivore will avoid eating them based on unpleasant past experiences ...
A chameleon successfully capturing prey with its tongue. In ecology, hunting success is the proportion of hunts initiated by a predatory organism that end in success. Hunting success is determined by a number of factors such as the features of the predator, timing, different age classes, conditions for hunting, experience, and physical capabilities.
Some prey make use of chemicals originating from predators, using these cues as an indicator of the level of predation risk and changing their morphology if need be. Changes in morphology caused by predator presence is known as predator-induced polyphenism, and occurs across a variety of animals.
The spider mite (Tetranychus urticae) can respond to predator volatiles in the environment and will choose to feed in areas without predator cues. [33] Similarly, spider mites are also able to sense damaged body parts of individuals of the same species, or conspecifics, and present the same avoidance behavior as with predator cues. [34]
