灵长类动物在不同的环境中使用不同类型的发声。一些研究最多的类型是长途电话或大声呼叫。这些发声与配偶防御、配偶吸引和资源防御有关,性选择在它们的进化中扮演了重要角色。专注于已知性别和年龄的识别个体,我们评估了阿根廷野生猫头鹰猴(Aotus azarae)种群中一种大声呼叫(叫声)的性二型性。我们发现的证据表明,性别二型性的呼叫结构,女性和男性只发出一种类型的呼叫,每个不同的主导频率和香农熵。此外,年龄相关的和性别特异性的差异,在调用使用也很明显,在响应删除一组成员。未来的声学数据将使我们能够评估是否存在个体特征,以及叫声的结构是否与猫头鹰猴的社会条件或对叫声特征变体的特定性别反应有关。这将提供更深入的见解,在这个和其他灵长类动物物种的语音机制调节配对债券和择偶策略的演变。
Primates use different types of vocalizations in a variety of contexts. Some of the most studied types have been the long distance or loud calls. These vocalizations have been associated with mate defense, mate attraction, and resource defense, and it is plausible that sexual selection has played an important role in their evolution. Focusing on identified individuals of known sex and age, we evaluated the sexual dimorphism in a type of loud calls (hoots) in a population of wild owl monkeys (Aotus azarae) in Argentina. We found evidence of sexual dimorphism in call structure, with females and males only emitting one type of call, each differing in dominant frequency and Shannon entropy. In addition, both age-related and sex-specific differences in call usage were also apparent in response to the removal of one group member. Future acoustic data will allow us to assess if there are individual characteristics and if the structure of hoot calls presents differences in relation to the social condition of owl monkeys or specific sex responses to variants of hoot calls’ traits. This will provide deeper insights into the evolution of vocal mechanisms regulating pair bonding and mate choice strategies in this and other primate species.
