摘要动物社会声音信号的地理差异可能会降低种群间的识别能力，从而可能促进分类交配、生殖隔离和物种形成。然而，人们对具有生态功能的声音信号的地理变异的社会后果知之甚少。蝙蝠回声定位叫声被认为具有双重功能；它们不仅用于定位和觅食，还用于交流。在这项研究中，我们研究了铁红菊头蝠对回声定位叫声中地理变异的行为反应。通过习惯性-去习惯性回放实验，我们发现东北中国蝙蝠在将原种群的回放切换到中东部中国蝙蝠和西南中国蝙蝠后，都表现出了明显的反应。通过双选择回放实验，我们发现东北地区的中国蝙蝠比中部东部地区的中国蝙蝠对回声定位叫声的反应更强烈。我们的研究结果表明，在二选一的情况下，铁氏菊头蝠能够区分本地种群和外来种群的回声定位叫声，并且本地种群的回声定位叫声比外来种群的回声定位叫声更受欢迎。这项研究支持蝙蝠回声定位叫声的交流潜力，并提供了关于蝙蝠对回声定位叫声的地理差异的辨别能力和行为偏好的洞察。意义陈述本研究为蝙蝠回声定位叫声中的交流作用提供了行为证据，并表明蝙蝠更普遍地存在回声定位叫声的双重功能。此外，本研究提供了蝙蝠对回声定位叫声频率变化的辨别能力和偏好，有助于更好地理解生态声信号的地理进化如何影响种群之间的识别能力。
AbstractThe geographical variation in animals’ social acoustical signals can reduce recognition across populations and may thus promote assortative mating, reproductive isolation and speciation. However, the social consequences of geographical variation in acoustical signals serving an ecological function are poorly known. Bat echolocation calls are considered to have a dual function; they are used not only for orientation and foraging but also for communication. In this study, we studied the behavioural response ofRhinolophus ferrumequinumto geographical variation in echolocation calls. Using habituation-dishabituation playback experiments, we found that all tested bats from northeast China exhibited obvious responses after switching playback from their own population to those from central east China and southwest China. Using two-choice playback experiments, we showed that the bats from northeast China responded more strongly to echolocation calls from their own population than to those from central east China. Our results demonstrate thatRhinolophus ferrumequinumis able to discriminate between echolocation calls of its local population and a foreign one and that local echolocation calls are preferred over foreign ones in a two-choice context. This study supports the communicative potential of bat echolocation calls and provides insight into the discrimination ability and behavioural preference of bats with respect to geographical variation in echolocation calls.Significance statementThis study provides behavioural evidence for the communicative role in echolocation calls and indicates that a dual function of echolocation calls exists more commonly in bats. Moreover, this study provides insight into the discrimination ability and preference of bats with respect to frequency variation in echolocation calls and contributes to a better understanding of how geographical evolution in ecological acoustical signals may affect the ability of recognition between populations.
