女性的选择可以推动奢侈的男性特征的进化。在无脊椎动物中，先前的社会经验对雌性选择的影响直到最近才被考虑。为了更好地了解经验介导的可塑性在女性选择的进化意义，我们调查的影响，在饲养过程中的声学经验对女性的反应，男性的歌曲在外地蟋蟀Teleogryllus oceanicus。听觉体验在这个物种中具有独特的生物学意义：形态突变使夏威夷考艾岛上90%以上的雄性在不到20代的时间里保持沉默，阻碍了雌性寻找潜在配偶的能力。在无声的条件下模仿考艾岛饲养的女性较少歧视的男性呼叫歌曲，更响应回放，与女性相比，在饲养过程中经历的歌曲。据我们所知，我们的研究结果是第一次证明长期影响的声音经验的节肢动物，并建议女性T。海洋生物也许能够通过增加它们对少数剩余信号的反应来补偿远距离雄性性信号的减少。了解经验介导的可塑性在女性选择的适应意义提供了洞察过程，促进快速进化的变化和形状的性选择压力在自然种群。
Female choice can drive the evolution of extravagant male traits. In invertebrates, the influence of prior social experience on female choice has only recently been considered. To better understand the evolutionary implications of experience-mediated plasticity in female choice, we investigated the effect of acoustic experience during rearing on female responsiveness to male song in the field cricket Teleogryllus oceanicus. Acoustic experience has unique biological relevance in this species: a morphological mutation has rendered over 90 per cent of males on the Hawaiian island of Kauai silent in fewer than 20 generations, impeding females' abilities to locate potential mates. Females reared in silent conditions mimicking Kauai were less discriminating of male calling song and more responsive to playbacks, compared with females that experienced song during rearing. Our results to our knowledge, are the first demonstration of long-term effects of acoustic experience in an arthropod, and suggest that female T. oceanicus may be able to compensate for the reduced availability of long-range male sexual signals by increasing their responsiveness to the few remaining signallers. Understanding the adaptive significance of experience-mediated plasticity in female choice provides insight into processes that facilitate rapid evolutionary change and shape sexual selection pressure in natural populations.
