蝙蝠表现出多样化和复杂的社会交际词汇，其中一些被认为是在发展过程中学习。这种产生习得的、物种特异性的发声的能力--在动物王国中是一种罕见的特征--需要高度的发声可塑性。蝙蝠在高度复杂和动态的社会环境中生活得非常长，这表明它们在成年后也可能保持高度的声音可塑性，就像人类一样。在这里，我们报告持久的声音可塑性成年蝙蝠（Rousettus aegyptiacus）暴露在宽带，声扰动。我们的研究结果表明，成年蝙蝠不仅可以修改其发声的不同参数，而且这些变化即使在噪音停止后也会持续存在-在某些情况下持续数周或数月。结合起来，这些发现强调了蝙蝠作为声音可塑性研究的模型生物的潜在重要性，包括在成年期。
Bats exhibit a diverse and complex vocabulary of social communication calls some of which are believed to be learned during development. This ability to produce learned, species-specific vocalizations - a rare trait in the animal kingdom - requires a high-degree of vocal plasticity. Bats live extremely long lives in highly complex and dynamic social environments, which suggests that they might also retain a high degree of vocal plasticity in adulthood, much as humans do. Here, we report persistent vocal plasticity in adult bats (Rousettus aegyptiacus) following exposure to broad-band, acoustic perturbation. Our results show that adult bats can not only modify distinct parameters of their vocalizations, but that these changes persist even after noise cessation - in some cases lasting several weeks or months. Combined, these findings underscore the potential importance of bats as a model organism for studies of vocal plasticity, including in adulthood.
