在许多非人类灵长类动物中，社会地位和繁殖成功之间的联系是有争议的，许多早期研究集中在交配成功上。我们使用雄性猕猴之间的实际父权差异来研究这种关系。我们分析了14项研究的数据，代表了该属的6个物种和3个谱系。我们发现，即使在控制了不同研究之间的系统发育(物种和谱系)、空间限制和遗传技术后，仍存在中等规模、正向和显著的关联。被研究的猕猴种群是研究之间唯一不同的因素，也是最终评估这种关系的重要考虑因素。我们的发现支持这一假设，即雄性猕猴通过在其群体中获得较高的社会地位来获得有利的生殖输出。即使在可供选择的生殖策略和有限的控制模式可能解释所观察到的生殖倾斜的很大比例的灵长类群体中，来自社会地位的健康益处也是显而易见的，并可能有助于复杂的社会阶层的演变。目前在这些物种中发现的阳离子。(C)2009年，动物行为研究协会。爱思唯尔有限公司出版。保留所有权利。
The connection between social status and reproductive success is contentious in many nonhuman primates, with many early studies focusing on mating success. We examined this relationship in macaques using actual paternity differences between males. We analysed data from 14 studies, representing six species and the three lineages of the genus. We found a medium-size, positive and significant association even after controlling for phylogeny ( species and lineage), spatial constraints and genetic techniques that differed between the studies. The population of macaques studied was the only factor to differ between studies and to be of important consideration for the final evaluation of the relationship. Our findings support the hypothesis that male macaques obtain advantageous reproductive output through acquisition of high social status in their groups. Even in primate groups where alternative reproductive tactics and limited control models may explain a high proportion of the reproductive skew observed, the fitness benefits derived from social status are evident and are likely to have contributed to the evolution of the complex social strati. cation found at present in these species.
