In the evolutionary arms race between predators and their prey, prey often evolve to be as cryptic as they can, while predators in turn hone their sensory strategies to detect prey. Examinations of the sensory strategies implemented by predators to detect their prey, as well as the ecological consequences of these interactions, are at the crux of understanding and predicting predator–prey dynamics. We review the sensory strategies used by predators that rely on private information (attending directly to cues and signals generated by their prey) and those that gather social information (attending to the signals and behaviours of others). We focus our enquiry on bats, an ideal group to shed light on these questions given their ecological diversity, varied foraging strategies and wide range of social behaviours. We discuss the costs and benefits of using private and social information for foraging. We investigate diverse strategies of information use and examine the effects different predatory strategies have on predator sensory systems. We provide an overview of the sensory ecology of information use in hunting in bats and, by identifying current gaps in knowledge, highlight fruitful directions for future research.

检测猎物的挑战：掠食性蝙蝠的私人和社会信息使用

在捕食者和猎物之间的进化军备竞赛中，猎物通常会进化得尽可能地神秘，而捕食者反过来会磨练他们的感官策略来检测猎物。检查捕食者为检测猎物而实施的感官策略，以及这些相互作用的生态后果，是理解和预测捕食者-猎物动态的关键。我们回顾了捕食者依赖私人信息（直接关注猎物产生的线索和信号）和收集社会信息（关注他人的信号和行为）的感官策略。我们将调查重点放在蝙蝠上，考虑到它们的生态多样性、不同的觅食策略和广泛的社会行为，蝙蝠是阐明这些问题的理想群体。我们讨论了使用私人和社会信息进行觅食的成本和收益。我们调查了信息使用的不同策略，并检查了不同的掠夺性策略对捕食者感官系统的影响。我们概述了蝙蝠狩猎中信息使用的感官生态学，并通过确定当前的知识差距，突出未来研究的富有成效的方向。可以在本文的支持信息中找到免费的普通语言摘要。突出未来研究的富有成果的方向。可以在本文的支持信息中找到免费的普通语言摘要。突出未来研究的富有成果的方向。可以在本文的支持信息中找到免费的普通语言摘要。
