Anthropogenic noise can interfere with environmental information processing and thereby reduce survival and reproduction. Receivers of signals and cues in particular depend on perceptual strategies to adjust to noisy conditions. We found that predators that hunt using prey sounds can reduce the negative impact of noise by making use of prey cues conveyed through additional sensory systems. In the presence of masking noise, but not in its absence, frog-eating bats preferred and were faster in attacking a robotic frog emitting multiple sensory cues. The behavioral changes induced by masking noise were accompanied by an increase in active localization through echolocation. Our findings help to reveal how animals can adapt to anthropogenic noise and have implications for the role of sensory ecology in driving species interactions.
人为噪声会干扰环境信息处理，从而降低生物的生存和繁殖能力。信号和提示的接收者尤其依赖于感知策略来适应嘈杂的环境。我们发现，利用猎物声音捕猎的捕食者可以通过利用通过其他感觉系统传递的猎物线索来减少噪声的负面影响。在存在掩蔽噪声的情况下，但不存在掩蔽噪声的情况下，食蛙蝙蝠更喜欢并更快地攻击发出多种感觉提示的机器青蛙。掩蔽噪声引起的行为变化伴随着通过回声定位进行主动定位的增加。我们的发现有助于揭示动物如何适应人为噪声，并对感官生态学在驱动物种相互作用中的作用具有启示意义。
