Most organisms live in environments that have been altered by humans via habitat destruction, the spread of exotic species, harvesting, pollution or climate change. These changes can alter the delicate balance between predators and prey, by altering the way prey can detect, recognize or assess the risk associated with potential threats. These situations occur if (1) the new environment itself masks the cues used by prey to detect predators; (2) a novel stressor or toxic compound prevents prey from properly recognizing a predation threat; or (3) prey misjudge a risky or safe situation because they use information that was reliable in their past environment, but no longer relevant in the modified one.

大多数生物都生活在人类通过栖息地破坏，外来物种的传播，收获，污染或气候变化而改变的环境中。这些变化可以通过改变猎物可以检测，识别或评估与潜在威胁相关的风险的方式来改变掠食者和猎物之间的微妙平衡。如果（1）新环境本身掩盖了猎物用于检测捕食者的提示，则会发生这些情况； （2）一种新型的压力源或有毒化合物可防止猎物正确识别捕食威胁；或（3）捕食误判存在风险或安全的情况，因为它们使用了过去的环境中可靠的信息，但不再与经过修改的信息相关。
