在整个哺乳动物物种中，在生产的空气中发声的形态和生理的限制，建议导致的共同点，在声乐传达的声学特征的呼叫者的特定属性，如唤醒和个人身份。为了探讨这一假设，我们研究了内和个体间的声音变化，树（树鼩 belangeri）的喋喋不休的电话。这些电话是由干扰范例实验诱导的，并且与受试者的两个定义的唤醒状态有关。动物的唤醒状态主要是由受试者对新环境的习惯化来操作的，另外还由树鼩的压力行为指标（尾部位置和立毛）来确定。我们调查是否唤醒状态和指标的呼叫者，即个人身份和性别的功能，传达声学。逐帧的视频和多参数声音分析显示，唤醒和身份，但不是性别的呼叫者可靠地预测频谱时间变化的声音结构。此外，年龄或体重对个体特定的声学特征没有影响。类似的结果，在另一种呼叫类型的树鼩和其他哺乳动物谱系的可比研究结果提供的证据表明，在生产的空气中发声哺乳动物的生理和形态的限制，导致共同的声学特征传达唤醒和身份，分别。
Across mammalian species, comparable morphological and physiological constraints in the production of airborne vocalisations are suggested to lead to commonalities in the vocal conveyance of acoustic features to specific attributes of callers, such as arousal and individual identity. To explore this hypothesis we examined intra- and interindividual acoustic variation in chatter calls of tree shrews (Tupaia belangeri). The calls were induced experimentally by a disturbance paradigm and related to two defined arousal states of a subject. The arousal state of an animal was primarily operationalised by the habituation of the subject to a new environment and additionally determined by behavioural indicators of stress in tree shrews (tail-position and piloerection). We investigated whether the arousal state and indexical features of the caller, namely individual identity and sex, are conveyed acoustically. Frame-by-frame videographic and multiparametric sound analyses revealed that arousal and identity, but not sex of a caller reliably predicted spectral–temporal variation in sound structure. Furthermore, there was no effect of age or body weight on individual-specific acoustic features. Similar results in another call type of tree shrews and comparable findings in other mammalian lineages provide evidence that comparable physiological and morphological constraints in the production of airborne vocalisations across mammals lead to commonalities in acoustic features conveying arousal and identity, respectively.
