抽象。雄性动物发出的长距离叫声在脊椎动物中很常见。人们提出了一些假说来解释灵长类动物中雄性长距离叫声的特征及其系统发育分布，但雄性长距离叫声的功能还有待全面验证。我们使用系统发育比较的方法来调查男性长途电话的功能的假设。我们专注于配偶防御假说，该假说指出，男性长途电话功能在性内竞争配偶，但我们也研究了涉及资源防御，配偶吸引力和栖息地的因素。对158种灵长类动物雄性远距离叫声的系统发育重建表明，雄性远距离叫声的存在是其祖先的状态。雄性远距离鸣叫的携带距离与家域的大小相关，这与雄性远距离鸣叫在保卫配偶、吸引配偶、保卫资源等方面的作用是一致的。然而，男性的性内竞争的措施没有与男性长途电话的演变。进化转型只有部分相关的因素与配偶的吸引力。相反，雄性长途电话的最强相关性是活动期，体重，家庭范围，栖息地和一些资源防御措施。我们的研究结果是一致的长途电话生产作为一个昂贵的信号，但物种内的详细研究需要评估这些成本和功能的长途电话在个别情况下。如果您访问这篇文章，请访问http://dx.doi.org/10.1007/。
Abstract. Long-distance calls produced by males are common among vertebrate species. Several hypotheses have been proposed to explain features of male long-distance calls and their phylogenetic distribution in primates, but the putative functions of male long-distance calls have yet to be tested comprehensively. We used phylogenetic comparative methods to investigate hypotheses for the function of male long-distance calls. We focused on the mate defense hypothesis, which states that male long-distance calls function in intra-sexual competition for mates, but we also examined factors involving resource defense, mate attraction, and habitat. Phylogenetic reconstruction of male long-distance calls in 158 primate species indicates that the presence of male long-distance calls is the ancestral state. The carrying distance of male long-distance calls is correlated with the size of the home range, which is consistent with the role of male long-distance calls in defending mates, attracting mates, and defending resources. However, measures of male intra-sexual competition were not associated with the evolution of male long-distance calls. Evolutionary transitions were only partly correlated with factors related to mate attraction. Instead, the strongest correlates of male long-distance calls were activity period, body mass, home range, habitat and some measures of resource defense. Our results are consistent with long-distance call production as a costly signal, but detailed study within species is required to assess these costs and the functions of long-distance calls in individual cases.
