Paternal kin discrimination using acoustic

项目摘要

In primates, kinship plays a central role in structuring social relationships between individuals. Among rhesus macaques (Macaca mulatta) strong evidence exists that (i) maternally related individuals recognize each other using acoustic cues and (ii) that most likely familiarity is the underlying mechanism to identify maternal kin. However, recognizing paternally related individuals such as paternal half-siblings (individuals sired by the same male, but born to different mothers) is probably more difficult as most female primates mate with multiple males during likely conception. Nevertheless, there is a growing body of evidence suggesting that primates socially favor their paternal kin over nonkin, and that vocalization might play a role in paternal kin discrimination. To date, it remains unknown what cues and mechanisms are used in paternal kin discrimination. The current project is set up to test (1) whether information signaling paternal relatedness is encoded in the acoustic structure of rhesus macaque vocalizations, and (2) to clarify the mechanism underlying paternal kin discrimination (with familiarity and phenotype matching being the most likely mechanisms). For the purpose of this study we will combine fine-tuned acoustic analyses with detailed data on genetic relatedness. The underlying mechanisms will be investigated using playback experiments. The results of the study will fundamentally improve our knowledge on the impact of kinship upon the evolution of social behavior.

在灵长类动物中，亲属关系在建立个人之间的社会关系中起着核心作用。在恒河猕猴（Macaca mulatta）中，有强有力的证据表明（i）使用声学提示彼此认识，（ii）最有可能的熟悉程度是鉴定母亲亲戚的基本机制。但是，认识到父亲界相关的个体，例如父亲的半兄弟姐妹（由同一男性抚养，但出生于不同母亲的人）可能会更加困难，因为大多数女性灵长类动物在可能的概念期间都与多个男性相伴。然而，越来越多的证据表明，灵长类动物在社会上偏爱父亲的亲戚而不是非金属，而且发声可能在父亲的亲属歧视中发挥作用。迄今为止，尚不清楚父亲亲属歧视中使用了哪些提示和机制。当前的项目设置为测试（1）是否在恒河猕猴发声的声学结构中编码信息信号传导父亲的关系，以及（2）阐明父亲亲属歧视的机制（熟悉性和表型匹配是最可能的机制）。出于这项研究的目的，我们将将微调的声学分析与遗传相关性的详细数据相结合。基本机制将使用播放实验研究。该研究的结果将从根本上提高我们对亲属关系对社会行为发展的影响的了解。
