识别亲属的能力对适合度有重要影响，因为它可以允许亲属偏见的附属行为和避免与近亲交配。虽然近亲偏见的存在和影响已经得到了广泛的研究，但人们对动物识别近亲的过程知之甚少。在这里，我们研究了白面卷尾猴（Cebus capucinus）可能用来识别同父异母兄弟姐妹和近亲的潜在线索。我们重点研究了哥斯达黎加洛玛斯巴布达尔种群的130只野生卷尾猴（N = 65只雌性幼猴）一岁后的情况。结果表明：(1)在半兄弟姐妹及以上水平上，婴儿与成年雄性和未成年雄性的亲缘关系可以通过雄性α地位、空间接近度和年龄接近度来预测；(2)在半兄弟姐妹及以上水平上，婴儿与成年雌性和未成年雄性的亲缘关系可以通过空间接近度来预测（但不包括年龄接近度）。此外，(1)男性α地位和婴儿与成年男性的空间接近性也可以预测婴儿父亲的身份；(2)年龄接近性（但不具有空间接近性）可以预测父亲的兄弟关系。这些结果表明，幼年卷尾猴可以获得多种线索来表达近亲关系和父系亲属关系，尽管婴儿在以后的生活中是否会使用这些线索还有待于未来的研究。(c) 2016年动物行为研究协会。Elsevier Ltd.出版。版权所有。
The ability to recognize kin has important impacts on fitness because it can allow for kin-biased affiliative behaviours and avoidance of mating with close kin. While the presence and effects of kin biases have been widely studied, less is known about the process by which animals recognize close kin. Here we investigate potential cues that white-faced capuchin monkeys, Cebus capucinus, may use to detect half siblings and closer kin. We focus on the first year of life in a sample of 130 infant (N = 65 infant females) wild capuchins from the Lomas Barbudal population in Costa Rica. We show that (1) infant relatedness to juvenile and adult males at the level of half sibling and higher can be predicted by male alpha status, spatial proximity and age proximity, and that (2) infant relatedness to juvenile and adult females at the level of half sibling or higher can be predicted by spatial proximity (but not age proximity). Furthermore, (1) the identities of infants' fathers can also be predicted by male alpha status and the spatial proximity between infants and adult males, and (2) age proximity (but not spatial proximity) is predictive of paternal sibship. These results suggest that infant capuchins have access to multiple cues to close relatedness and paternal kinship, although whether infants use these cues later in life remains to be explored in future research.
