Evolution of signalling through pursuit deterrence in a two-prey model using game theory
2018, Animal BehaviourCitation Excerpt :If the signal decreases the expected value of the patch such that it is lower than the predator's missed opportunity costs, then the predator will leave the focal patch, resulting in successful pursuit deterrence. While previous models have considered a reduction in value of just the signaller (Getty, 2002), we consider the value of the entire patch, i.e. both prey in the patch where a signal has occurred drops considerably as a result of the signal. A signalling prey clearly benefits if the signal deters attack.
Perceptual advertisement by the prey of stalking or ambushing predators
2012, Journal of Theoretical BiologyCitation Excerpt :Although both parties can potentially gain from such signalling, its evolutionary stability is not trivial, because there can be an opportunity for prey to cheat and signal that they have detected the predators on occasions when they suspect that a predator is around but they are not certain. Bergstrom and Lachmann (2001) developed a game theoretical model to explore the conditions required for evolutionary stability in the face of such a danger of cheating (this model was later refined by Getty (2002)). Bergstrom and Lachmann (2001) envisage prey receiving a stimulus of value x at a certain time.
