超声发声(USV)是小鼠多模式交流的重要组成部分；然而，对野生小鼠个体产生USV的行为背景知之甚少。利用遥感方法，我们记录了自由生活的加州拟青霉个体的紫外线。由于成年雄性和雌性共同承担着抚养后代和保卫领地的职责，我们预测雄性和雌性将在相似的行为背景下产生USVs，具有相似的光谱和时间特征。我们发现，成年雄性和雌性斑潜蝇产生USVs，最常见的主题是单音节、双音节和三音节发音。男性和女性的USV在类型、数量、光谱和时间特征上没有显著差异。加州拟青霉在单独和与另一只小鼠相处时会产生USV，而三音节发声(3SV)基序的第一个音节相对较长，与单独使用一只小鼠相比，在另一只小鼠在场的情况下更有可能产生USV。当个体在配偶或非配偶在场的情况下产生USV时，发声的可能性以及发声的光谱和时间特征没有区别。男性和女性在相同的行为背景下产生紫外线。因此，与与养育和领土防御有关的其他行为一样，雄性和雌性的紫外线是在相似的行为背景下产生的，具有相似的光谱和时间特征。(C)2011年，动物行为研究协会。爱思唯尔有限公司出版。保留所有权利。
Ultrasonic vocalizations (USV) are an important part of multimodal communication in mice; however, nothing is known about the behavioural context of USV production by individual mice in the wild. Using remote-sensing methods we recorded USVs from individual adult free-living Peromyscus californicus. Because adult male and female P. californicus share duties in rearing offspring and defending territories, we predicted that male and female P. californicus would produce USVs in similar behavioural contexts and with similar spectral and temporal characteristics. We found that adult male and female P. californicus produced USVs, with the most common motifs being one-, two-and three-syllable vocalizations. USVs of males and females did not differ significantly in type or number, or in spectral or temporal characteristics. Peromyscus californicus produced USVs when alone and when they were with another mouse, and the three-syllable vocalization (3SV) motif, which has a relatively long first syllable, was more likely to be produced in the presence of another mouse than when a mouse was alone. The likelihood of vocalizing and the spectral and temporal characteristics of vocalizations did not differ when an individual was producing a USV in the presence of a mate or nonmate. Males and females produced USVs in the same behavioural contexts. Thus, as with other behaviours associated with parenting and territorial defence in P. californicus, USVs of males and females are produced in similar behavioural contexts and have similar spectral and temporal characteristics.
