    Abstract: The traditional functional responses in predator-prey models do not explicitly include the effects of prey toxin. And optimal foraging theory mainly considers maximizing energy intake from prey, while prey toxicity is omitted from the strategy. However, a lot of evidence indicates that prey toxins set an upper limit on the predator's predation, the... Show More
