“…The genes encoding these proteins fall into seven subfamilies (A–G) and have ancient eukaryotic origins [ 194 ]. ABCG2 or ABCG2-like genes have been found in 41 bird species, and ABCG2-like genes have been lost in only five species [ 195 ]. We recommend sequencing the ABC transporters and comparing expression patterns in resistant and non-resistant predators to determine whether these proteins are upregulated to protect important tissues.…”

Predator–prey interactions have long served as models for the investigation of adaptation and fitness in natural environments. Anti-predator defences such as mimicry and camouflage provide some of the best examples of evolution. Predators, in turn, have evolved sensory systems, cognitive abilities and physiological resistance to prey defences. In contrast to prey defences which have been reviewed extensively, the evolution of predator counter-strategies has received less attention. To gain a comprehensive view of how prey defences can influence the evolution of predator counter-strategies, it is essential to investigate how and when selection can operate. In this review we evaluate how predators overcome prey defences during (i) encounter, (ii) detection, (iii) identification, (iv) approach, (v) subjugation, and (vi) consumption. We focus on prey that are protected by cardiotonic steroids (CTS)—defensive compounds that are found in a wide range of taxa, and that have a specific physiological target. In this system, coevolution is well characterized between specialist insect herbivores and their host plants but evidence for coevolution between CTS-defended prey and their predators has received less attention. Using the predation sequence framework, we organize 574 studies reporting predators overcoming CTS defences, integrate these counter-strategies across biological levels of organization, and discuss the costs and benefits of attacking CTS-defended prey. We show that distinct lineages of predators have evolved dissecting behaviour, changes in perception of risk and of taste perception, and target-site insensitivity. We draw attention to biochemical, hormonal and microbiological strategies that have yet to be investigated as predator counter-adaptations to CTS defences. We show that the predation sequence framework will be useful for organizing future studies of chemically mediated systems and coevolution.

The long-term evolution of species involved in predator-prey interactions has resulted in many examples of specialised prey defences. The methods that predators use to mitigate prey defences has received less attention. The frequent reference to an arms races or coevolution without clear evidence that both strategies evolved under the influence of each other is problematic. In this review, we use the predation sequence approach as a framework to investigate how predators can evolve traits that allow continued interaction with dangerous prey and we evaluate the evidence for an arms race. We synthesise results from 574 records of predation on prey that are protected by cardiotonic steroids (CTS) – defensive compounds that are found in taxa ranging from toads, to fireflies, to numerous plants, and that have a specific physiological target. We find evidence that distinct lineages of predators share generalised mitigation strategies, and in the latter stages of the predation sequence these strategies are more specific and exploitative behavioural, physiological, and molecular adaptations. In most cases the available evidence does not fulfil the theoretical requirements for arms race dynamics. Our review framework helps to direct future research on what kinds of prey defences appear most profitable for predators to overcome, and what kinds of predatory mitigation strategies are best for a given suite of defences.
