“…By contrast, mimicry biases the characteristics of a mimic to correspond with information that is emitted by a model. In wrongly identifying the mimic as the model, the target receiver (the dupe) releases a benefit for the mimic while paying some form of cost for being misled (Figure 1; Dalziell and Welbergen, 2016;Font, 2019). Mimetic traits persist where there is a net fitness benefit for receivers, since correct detection of a true signal from the model is nevertheless advantageous (Stevens, 2013;Font, 2019).…”

Predators have profound effects on prey behavior and some adult brood parasites use predator resemblance to exploit the antipredator defenses of their hosts. Clarifying host perception of such stimuli is important for understanding the adaptive significance of adult brood parasite characteristics, and the mechanisms by which they misdirect hosts. Here I review the literature to explore the adaptive basis of predator resemblance in avian brood parasites, and natural variation in host responses to these stimuli. I also provide a framework for the information ecology of predator resemblance, which is based on the principles of signal detection theory and draws from empirical evidence from the common cuckoo, Cuculus canorus, as the most widely studied system. In this species, visual and acoustic hawk-like stimuli are effective in manipulating host defenses. Overall, contrasts across host responses suggest that different modalities of information can have independent effects on hosts, and that predator resemblance takes advantage of multiple sensory and cognitive processes. Host perception of these stimuli and the degree to which they are processed in an integrated manner, and the physiological processes underlying regulation of the responses, present new avenues for brood parasitism research.

“…In such cases, the mimic is not misidentified by the predator but triggers the predator's pre-adapted response to a model, which benefits the mimic. This situation can lead to a coevolutionary arms race known as ‘sensory trap' [26,46,47].…”

“…1‘Mimicry is resemblance/similarity in appearance and/or behaviour between a mimic and a model that provides a selective advantage to the mimic because it affects the behaviour of a receiver causing it to misidentify the mimic and that evolved (or is maintained by selection) because of those effects’ [26]. …”

Perception-driven dynamics of mimicry based on attractor field model

2021

View full text Add to dashboard Cite

We provide a formal account of an interface that bridges two different levels of dynamic processes manifested by mimicry: prey–prey interactions and predators' perception. Mimicry is a coevolutionary process between an animate selective agent and at least two similar organisms selected by agent's perception-driven actions. Attractor field model explains perceived similarity of forms by noting that in both human and animal cognition, morphologically intermediate forms are more likely to be perceived as belonging to rare rather than abundant forms. We formalize this model in terms of predators' perception space deformation using numerical simulations and argue that the probability of confusion between similar species creates pressure on the perception space, which in turn leads to inflation of regions of perception space with high density of species representations. Such inflation causes increased discrimination between species by a predator, which implies that adaptive mimicry could initially emerge more easily among atypical species because they do not need the same level of similarity to the model. We provide a theoretical instrument to conceptualize interdependence between objective measurable matrices and perceived matrices of the same external reality. We believe that our framework leads to a more precise understanding of the evolution of mimicry.
