在求偶过程中，发声可以成为雄性和雌性之间交换信息的双向渠道。虽然超声波发声（USVs）的雄性家鼠，小家鼠，在与女性的互动一直是一个重点的通信研究，在这种情况下，女性的发声仍然知之甚少。在与雄性小鼠的互动过程中，雌性小鼠会发出具有宽带谐波结构的声音（“宽带发声”或BBV），人类听众通常将其描述为“吱吱声”。我们测试的假设，即生产的BBV对应于男性和女性的行为，以及上下文变量，如发情期，通过测量BBV，USV和无声的行为在39个独特的男女配对。我们发现BBV与其他行为的关系取决于求爱的阶段。BBV的高发病率伴随着男性导向的踢和弓步的早期互动预测缺乏后来的男性安装和男性产生的'50 kHz谐波' USVs。相比之下，有显着的时间重叠BBV和50 kHz谐波USVs在求爱的后期阶段，可能是由安装事件驱动。BBV的声学非线性段的持续时间在女性之间变化显着，即使在与不同的男性的相互作用，但也不同的发情期内的女性。这些研究结果表明，发声可以发挥作用，在信号急性女性的动机状态，身份或发情状态在异性互动。由于BBV的信息承载功能相对容易测量，它们可能是一个有用的读数的负面动机状态适合许多研究和教育应用。(C)2017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。
Vocal production can be a two-way channel for the exchange of information between males and females during courtship. Although the ultrasonic vocalizations (USVs) of male house mice, Mus musculus, during interactions with females have been a focus of communication research, the vocalizations of females in this context remain poorly understood. During interactions with males, female mice produce audible vocalizations with a broadband harmonic structure ('broadband vocalizations', or BBVs) that are often described by human listeners as 'squeaks'. We tested the hypothesis that the production of BBVs corresponds to male and female behaviours, as well as to contextual variables like oestrous phase, by measuring BBVs, USVs and nonvocal behaviours during 39 unique male-female pairings. We found that the relationship of BBVs to other behaviours depends on the phase of courtship. A high incidence of BBVs accompanied by male-directed kicks and lunges early in interactions predicted a lack of later male mounting and male-produced '50 kHz harmonic' USVs. In contrast, there was significant temporal overlap between BBVs and 50 kHz harmonic USVs at later stages of courtship, potentially driven by mounting events. The duration of acoustically nonlinear segments of BBVs varied significantly among females, even across interactions with different males, but also varied across oestrous phase within females. These findings suggest that vocalizations could play a role in signalling acute female motivational state, identity or oestrous state during opposite-sex interactions. Since the information-bearing features of BBVs are relatively easily measured, they are potentially a useful readout of negative motivational state suitable for many research and educational applications.
