性内和性间交流对于动物的生存和繁殖成功至关重要。对于在繁殖或其他生理条件下循环的物种，可以调节感觉功能以在关键时刻优化交流。然而，人们对这种感觉可塑性在整个分类群中的广泛程度、是否在一个物种内以多种感觉或两性发生，以及涉及哪些潜在的调节物质和底物，知之甚少。因此，研究单个物种的感觉通讯调节可以为理解如何改变感觉能力以优化不同感觉通道和社会环境中显着信号的检测提供有价值的见解。非洲丽鱼科鱼Astatotilapia burtonius在求爱、领地和亲代照顾等社会环境中进行多模式交流，并表现出感官能力的可塑性。在这篇综述中，我们综合了关于视觉、听觉和化学感应通信如何在 A 中使用的已知信息。伯托尼在特定社会背景下和特定社会背景下，感觉功能如何受到个体的生殖、代谢和社会状态的调节，并讨论可能导致感觉能力和行为变化的潜在调节剂的可塑性证据。雌性的感觉可塑性主要与自然生殖周期相关，并具有改善对来自高质量雄性的求偶信号（视觉、听觉、化学感觉和可能的机械感觉）进行繁殖的功能。雄性感觉能力的可塑性似乎会改变它们检测其他雄性状态的能力，从而服务于领地所有权和未来的繁殖机会。不同类别的潜在调节剂或其受体（类固醇、神经肽和生物胺）的变化发生在外周感觉器官（眼、内耳和嗅觉上皮）和中枢视觉、嗅觉和听觉处理区域，表明促进感觉功能可塑性的复杂机制。这种类型的感觉可塑性在 A 的雄性和雌性中表现出来。伯托氏菌在不同动物中的分布可能比目前意识到的更为广泛，未来的研究应该采取综合和比较的方法，以更好地了解调节跨类群沟通能力的直接和最终机制。
Intra- and inter-sexual communications are vital to the survival and reproductive success of animals. In species that cycle in and out of breeding or other physiological condition, sensory function can be modulated to optimize communication at crucial times. Little is known, however, about how widespread this sensory plasticity is across taxa, whether it occurs in multiple senses or both sexes within a species, and what potential modulatory substances and substrates are involved. Thus, studying modulation of sensory communication in a single species can provide valuable insights for understanding how sensory abilities can be altered to optimize detection of salient signals in different sensory channels and social contexts. The African cichlid fishAstatotilapia burtoniuses multimodal communication in social contexts such as courtship, territoriality, and parental care and shows plasticity in sensory abilities. In this review, we synthesize what is known about how visual, acoustic, and chemosensory communication is used inA. burtoniin inter- and intra-specific social contexts, how sensory funtion is modulated by an individual’s reproductive, metabolic, and social state, and discuss evidence for plasticity in potential modulators that may contribute to changes in sensory abilities and behaviors. Sensory plasticity in females is primarily associated with the natural reproductive cycle and functions to improve detection of courtship signals (visual, auditory, chemosensory, and likely mechanosensory) from high-quality males for reproduction. Plasticity in male sensory abilities seems to function in altering their ability to detect the status of other males in the service of territory ownership and future reproductive opportunities. Changes in different classes of potential modulators or their receptors (steroids, neuropeptides, and biogenic amines) occur at both peripheral sensory organs (eye, inner ear, and olfactory epithelium) and central visual, olfactory, and auditory processing regions, suggesting complex mechanisms contributing to plasticity of sensory function. This type of sensory plasticity revealed in males and females ofA. burtoniis likely more widespread among diverse animals than currently realized, and future studies should take an integrative and comparative approach to better understand the proximate and ultimate mechanisms modulating communication abilities across taxa.
