Thorough examinations of purported cases of reproductive character displacement are critical for reaching an understanding of the role of reinforcement in the evolution of reproductive barriers between closely related species. In this paper, we report the results of an extensive investigation of male calling song variation in the ground crickets, Allonemobius fasciatus and A. socius. Contrary to the results of an earlier study, we uncovered little evidence of displacement of songs in areas of overlap. We discuss explanations for the lack of displacement as well as for the discrepancies between the results of the current study and those of the earlier study.
对所谓的生殖特征取代案例进行全面研究，对于理解强化在近缘物种间生殖隔离进化中的作用至关重要。在本文中，我们报告了对草螽属的条纹草螽和社会草螽雄性求偶鸣叫变异进行广泛调查的结果。与早期研究结果相反，我们几乎没有发现重叠区域鸣声发生取代的证据。我们讨论了缺乏取代现象的原因，以及当前研究结果与早期研究结果存在差异的原因。
