多模式交流在动物王国中很常见。当动物通过刺激两个或更多的接收感觉系统来表现时，就会发生这种情况，当选择倾向于用多种方式向同种动物发送信息时，就会出现这种情况。多模态显示行为的机制尚不清楚，特别是关于动物如何协调不同信号的产生。一个重要的问题是，多模态显示中的所有成分是否共享一个潜在的生理基础，或者不同的成分是否独立调节。我们研究了雄性激素受体（ARs）对婆罗洲岩蛙（Staurois parvus）多模态展示节目中视觉和声音信号成分产生的影响。为了评估AR在信号产生中的作用，我们用抗雄激素氟他胺（FLUT）治疗生殖活跃的成年雄性，并测量了多模态显示中每个成分信号的表现。我们的研究结果表明，阻断AR抑制了多种视觉信号的产生，包括一种被称为“脚旗”的明显视觉信号，这是通过在身体上方旋转后肢产生的。然而，FLUT处理没有引起声音信号行为的可测量变化，也没有引起雄性叫声的频率或精细时间特性的变化。因此，我们的研究表明，激活AR并不是多种信号协调的生理先决条件，因为它要么不能调节雄性显示库中的所有信号行为，要么只能以情境依赖的方式进行调节。
Multimodal communication is common in the animal kingdom. It occurs when animals display by stimulating two or more receiver sensory systems, and often arises when selection favors multiple ways to send messages to conspecifics. Mechanisms of multimodal display behavior are poorly understood, particularly with respect to how animals coordinate the production of different signals. One important question is whether all components in a multimodal display share an underlying physiological basis, or whether different components are regulated independently. We investigated the influence of androgen receptors (ARs) on the production of both visual and vocal signal components in the multimodal display repertoire of the Bornean rock frog (Staurois parvus). To assess the role of AR in signal production, we treated reproductively active adult males with the antiandrogen flutamide (FLUT) and measured the performance of each component signal in the multimodal display. Our results show that blocking AR inhibited the production of multiple visual signals, including a conspicuous visual signal known as the “foot flag,” which is produced by rotating the hind limb above the body. However, FLUT treatment caused no measurable change in vocal signaling behavior, or in the frequency or fine temporal properties of males’ calls. Our study, therefore, suggests that activation of AR is not a physiological prerequisite to the coordination of multiple signals, in that it either does not regulate all signaling behaviors in a male’s display repertoire or it does so only in a context-dependent manner.
