就像鸟类中的雀形目动物一样，哺乳动物中的啮齿动物也经历了巨大的辐射。与鸣禽类似，这种辐射与声音信号产生方式的关键创新的演变有关。最近对发声的解剖学和生理学基础的研究提供了一个机会来了解近似机制如何塑造声学变化以影响信号功能和进化。声学变化的范围从不同社会背景下个体内部的微妙变化到密切相关的物种之间的极端分歧。尽管人们对这种方式的认识有所增加，但相对较少的研究评估了个体内声学特征随时间的变化和/或这种变化的后果。此外，我们对促进和限制声学变化的机制的理解是有限的。在此，我们回顾了与鼠科和仓鼠科啮齿动物种内声学信号变化相关的个体发育、社会和内分泌因素，总结了这种变化的功能后果，并描述了声音显示背后的形态和生理适应。然后，我们提出了一个框架，用于开发相互信息的机制和功能研究，以探索信号阐述的演变。阐明种间和种内声音变化的原因和后果对于理解哺乳动物最大辐射中发声的进化和功能至关重要。(c) 2021 动物行为研究协会。由爱思唯尔有限公司出版。保留所有权利。
Like passerines among birds, rodents among mammals have experienced an enormous radiation. Similar to songbirds, this radiation is associated with the evolution of a critical innovation in how vocal signals are produced. Recent studies on the anatomical and physiological bases of vocal production provide an opportunity to understand how proximate mechanisms shape acoustic variation to influence signal function and evolution. Acoustic variation ranges from subtle changes within individuals in different social contexts to extreme divergence among closely related species. Despite increased appreciation of this modality, relatively few studies have assessed variability of acoustic features within individuals over time and/or the consequences of such variation. Moreover, our understanding of the mechanisms that promote and constrain acoustic variation is limited. Herein, we review ontogenetic, social and endocrine factors associated with intraspecific acoustic signal variation in murid and cricetid rodents, summarize the functional consequences of such variation and describe morphological and physiological adaptations underlying vocal displays. We then suggest a framework for developing mutually informative mechanistic and functional studies to explore the evolution of signal elaboration. Clarifying the causes and consequences of interspecific and intraspecific acoustic variation is critical to understanding the evolution and function of vocalizations in the largest radiation of mammals.(c) 2021 The Association for the Study of Animal Behaviour.
