尽管进化论预测，当父母照顾程度较高时，父母应该区分自己的后代和他人的后代，但在一些群体繁殖的哺乳动物中，强烈的选择压力预计会推动父母和后代之间相互认可的进化。尽管对鸟类和哺乳动物的后代歧视的研究不如父母歧视，但也有记录。夜间活动的蝙蝠在很大程度上依赖声音信号进行交流，尽管人们对蝙蝠幼崽是否能够仅根据母亲的叫声来识别母亲知之甚少。我们首先调查了波莫纳叶鼻蝙蝠的母性叫声在个体之间是否存在统计学差异。然后，我们通过回放实验测试了幼崽是否能识别母亲的叫声。母蝙蝠的回声定位脉冲和指令性叫声包含足够的个体特征，足以进行个体歧视。回放实验表明，幼崽对播放自己母亲的指令性叫声和播放另一位母亲的指令性叫声做出了更多的反应，但对播放自己母亲的指令性叫声和另一位母亲的回声定位脉冲没有反应，这表明后代可以区分自己母亲和其他母亲的指令性叫声，但不能区分回声定位脉冲。据我们所知，这是第一项利用蝙蝠母亲的指令性呼叫来引发幼崽发声的研究，也是第一项表明幼崽可以仅根据指令性呼叫来识别母亲的研究。这些结果促进了我们对声音信号在母子识别中的功能以及这种交流的适应性益处的理解，特别是在幼崽对母亲的识别至关重要的条件下。 (C) 2014 年动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Although evolutionary theory predicts that parents should discriminate between their own and others' offspring when levels of parental care are large, in some colonial breeding mammals, strong selective pressure would be expected to drive the evolution of mutual recognition between parents and offspring. Although less well studied than parental discrimination, in both birds and mammals, offspring discrimination of parents has also been documented. Nocturnal bats depend heavily on acoustic signals for communication, although little is known about whether bat pups can recognize their mothers based solely on maternal calls. We first investigated whether maternal calls of pomona leaf-nosed bats differ statistically among individuals. Then, we tested whether pups recognize their mothers' calls using a playback experiment. Echolocation pulses and directive calls of mother bats contain enough individual characteristics to allow for individual discrimination. Playback experiments showed that the pups responded with more vocalizations to playback of their own mother's versus another mother's directive calls, but not to playback of their own mother's versus another mother's echolocation pulses, suggesting that offspring can distinguish directive calls, but not echolocation pulses, of their own mother from those of other mothers. To our knowledge, this is the first study in which directive calls from bat mothers have been used to elicit vocalizations from pups and the first study to indicate that pups can recognize their mothers based solely on directive calls. These results advance our understanding of the function of acoustic signals in mothere-offspring recognition and the adaptive benefit of such communication, particularly the conditions under which a pup's recognition of its mother is critical.
