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，亲属关系在构建个体之间的社会关系中起着核心作用。在恒河猴（Macaca mulatta）强有力的证据存在，（i）母系相关的个人认识到对方使用声学线索和（ii），最有可能的熟悉性是潜在的机制，以确定母系亲属。然而，识别父系相关的个体，如父系半兄弟姐妹（由同一男性所生，但由不同母亲所生的个体）可能更困难，因为大多数雌性灵长类动物在可能的受孕期间与多个男性交配。然而，越来越多的证据表明，灵长类动物在社会上更喜欢他们的父系亲属而不是非亲属，并且发声可能在父系亲属歧视中发挥作用。到目前为止，它仍然是未知的线索和机制，在父系亲属歧视。目前的项目是建立测试（1）是否信息信号的父系相关性编码在恒河猴发声的声学结构，（2）澄清父系亲属歧视的机制（熟悉和表型匹配是最可能的机制）。为了这项研究的目的，我们将结合联合收割机微调声学分析与遗传相关性的详细数据。基本机制将使用回放实验进行研究。这项研究的结果将从根本上提高我们对亲属关系对社会行为演变的影响的认识。
