大多数动物在其生命中经历生殖过渡;例如，达到生殖成熟或在繁殖条件下循环。有些生殖转变是突然的，而另一些则是渐进的。在大多数情况下，两性之间交流的变化遵循这些生殖转变的时间进程，通常被认为是由类固醇激素协调的。我们知道很多关于激素控制鸟类和青蛙的交流行为，以及这些行为的中枢神经控制。类固醇激素对中枢神经系统结构的影响也引起了极大的兴趣，中枢神经系统结构控制着与生殖行为相关的通信信号的产生和接收。然而，外周感觉结构通常较少受到关注，尽管近年来人们的兴趣越来越大。越来越清楚的是，外周感觉系统在生殖交流中起着重要作用，在生殖条件下是可塑的，并且在某些情况下，这种可塑性可能是由类固醇激素介导的。在这篇文章中，我们讨论了最近的证据外周听觉结构在鸟类和青蛙的生殖交流中的作用，外周听觉系统的可塑性，以及类固醇激素在介导外周听觉系统对生殖交流的影响中的作用。我们专注于季节性和急性生殖过渡，介绍了激素在调节季节性模式中的作用的新数据，并对未来的工作提出建议。
Most animals experience reproductive transitions in their lives; for example, reaching reproductive maturity or cycling in and out of breeding condition. Some reproductive transitions are abrupt, while others are more gradual. In most cases, changes in communication between the sexes follow the time course of these reproductive transitions and are typically thought to be coordinated by steroid hormones. We know a great deal about hormonal control of communication behaviors in birds and frogs, as well as the central neural control of these behaviors. There has also been significant interest in the effects of steroid hormones on central nervous system structures that control both the production and reception of communication signals associated with reproductive behaviors. However, peripheral sensory structures have typically received less attention, although there has been growing interest in recent years. It is becoming clear that peripheral sensory systems play an important role in reproductive communication, are plastic across reproductive conditions, and, in some cases, this plasticity may be mediated by steroid hormones. In this article, we discuss recent evidence for the role of peripheral auditory structures in reproductive communication in birds and frogs, the plasticity of the peripheral auditory system, and the role of steroid hormones in mediating the effects of the peripheral auditory system on reproductive communication. We focus on both seasonal and acute reproductive transitions, introduce new data on the role of hormones in modulating seasonal patterns, and make recommendations for future work.
