性选择理论预测了男性的性特征和生殖成功之间的关系。这一预测已被广泛测试使用的复杂性鸟鸣作为一个模型的性状阐述。然而，出现了相互矛盾的结果。一些研究表明，拥有大剧目的男性享有生殖优势，而其他研究未能支持这一预测。为了从这种混合证据中做出一般性推论，我们使用荟萃分析方法对相关文献进行了定量分析。歌曲/交配成功关联的平均效应大小是显着的，但效果一般较弱，受出版偏见，混杂的非受控变量，并在检查的性状不同。由于物种特异性效应、交配系统差异和歌曲表型，效应大小在研究中是异质的。歌曲的复杂性和繁殖成功之间的关联程度是独立的性选择的强度，评估的程度，一夫多妻制和extrapair的父亲。我们的研究结果强调了考虑各种生物因素的重要性，以了解在不同物种中介导交配成功的剧目的作用。版权所有2011，牛津大学出版社。
The theory of sexual selection predicts a relationship between male sexual traits and reproductive success. This prediction has been tested extensively using the complexity of birdsong as a model for trait elaboration. However, contradictory results have emerged. Some studies have demonstrated that males with large repertoires enjoy a reproductive advantage, whereas other studies have failed to support this prediction. To make general inferences from this mixed evidence, we quantitatively reviewed the relevant literature using a meta-analytic approach. The mean effect size for the song/mating success association was significant, but the effects were generally weak, affected by publication bias, confounded by uncontrolled variables, and differing across the traits examined. Effect sizes were heterogeneous across studies due to species-specific effects, differences in mating systems, and song phenotypes. The degree of association between song complexity and reproductive success was independent of the strength of sexual selection, as assessed by the degree of polygyny and extrapair paternity. Our results highlight the importance of considering various biological factors to understand the role of repertoires in mediating mating success in different species.
