成年家鼠产生的超声波发声（USVs）是两性异形，并有歌曲的功能。为了测试USV是否在性求爱中发挥作用，我们研究了男性如何在暴露于不同性别和年龄的同种气味后产生USV，以及女性对男性USV的录制回放的吸引力。我们研究了野生来源的家鼠（F1从野生捕获的小家鼠），因为以前的工作几乎完全是在驯化的菌株。男性产生USV响应女性，但不男性或未成熟的女性尿气味，男性以较高的速度响应尿液从新的比熟悉的女性。雄性先前的社会经验对其对新鲜雌性尿液的USV反应没有影响，证实了实验室小鼠的研究。当播放时，女性更吸引USVs的新男性，并表现出偏好陌生的nonkin与熟悉的兄弟姐妹。我们的研究结果支持这样的观点，即雄性USV的功能是吸引配偶的求爱行为，并将先前对实验室品系的几项发现扩展到野生家鼠。我们还表明，USV是高度多样化的男性之间，但需要进一步的实验，以确定这些发声是否在社会（个人，兄弟姐妹或亲属）识别，避免近亲繁殖或其他形式的配偶选择中发挥作用。(C)2009年，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。
Adult house mice produce ultrasonic vocalizations (USVs) that are sexually dimorphic and have features of song. To test whether USVs play a role in sexual courtship, we examined how males produce USVs following exposure to scent from conspecifics of different sexes and ages, and also females' attraction to recorded playbacks of males' USVs. We studied wild-derived house mice (F1 from wild-caught Mus musculus musculus) since previous work has almost exclusively been on domesticated strains. Males produced USVs in response to female but not to male or immature female urinary scent, and males responded at a higher rate to urine from novel than familiar females. Males' prior social experience had no effect on their USV responses to fresh female urine, corroborating studies with laboratory mice. When presented with playbacks, females were more attracted to USVs of novel males, and showed a preference for unfamiliar nonkin versus familiar siblings. Our results support the idea that male USVs function as courtship behaviour to attract mates, and extend several previous findings on laboratory strains to wild house mice. We also show that USVs are highly diverse among males, but further experiments are needed to determine whether these vocalizations play a role in social (individual, sibling or kin) recognition, inbreeding avoidance or other forms of mate choice.
