在实验室中对啮齿动物的超声波进行了大量的研究，这些声音已经被很好地量化和表征。尽管在实验室中对小鼠产生的超声波进行研究的价值，但目前还不清楚这些声音是否以及何时在野外产生，以及它们在自然栖息地中如何发挥作用。我们在加州的长期研究网格上首次记录了两种自由生活的Peromyscus属小鼠（P. californicus和P. boylii）产生的超声波发声。在6个晚上，我们记录了65个独特的超声波发声短语。我们记录的超声波发声代表7种不同的图案。在每个主题中，有相当大的变化，在声学特性表明个人和上下文的变化，在这些物种的超声波的生产。在野生环境中发现的Peromyscus超声波发声突出了这些模式生物的行为中一个未被充分认识的组成部分。在野外检查超声波发声的能力提供了极好的机会来测试关于啮齿动物在自然环境中产生的超声波功能的假设。
There has been considerable research on rodent ultrasound in the laboratory and these sounds have been well quantified and characterized. Despite the value of research on ultrasound produced by mice in the lab, it is unclear if, and when, these sounds are produced in the wild, and how they function in natural habitats. We have made the first recordings of ultrasonic vocalizations produced by two free-living species of mice in the genus Peromyscus (P. californicus and P. boylii) on long term study grids in California. Over 6 nights, we recorded 65 unique ultrasonic vocalization phrases from Peromyscus. The ultrasonic vocalizations we recorded represent 7 different motifs. Within each motif, there was considerable variation in the acoustic characteristics suggesting individual and contextual variation in the production of ultrasound by these species. The discovery of the production of ultrasonic vocalizations by Peromyscus in the wild highlights an underappreciated component in the behavior of these model organisms. The ability to examine the production of ultrasonic vocalizations in the wild offers excellent opportunities to test hypotheses regarding the function of ultrasound produced by rodents in a natural context.
