蒙古沙鼠具有丰富的发声能力，在一个群体中观察到至少13种不同类型的叫声。本研究的目的是在一个标准化的环境中比较这些不同呼叫类型的交际价值。通过八臂径向迷宫量化了扬声器发出的发声的声定向行为。动物被观察到留在声源附近的时间较长的一段时间时，短的向上调频（bUFM）的电话，这是在看似友好的接触，而动物停留显着更长的时间远离扬声器时，拱形FM（AFM）的电话，这是由动物在严重的身体压力下产生的，提出。我们的数据表明，一个8臂的径向迷宫可以用来研究蒙古沙鼠发声的功能，并建议bUFM和AFM呼叫有沟通的目的，增加的概率，收件人同种方法或逃离声源，分别。
Mongolian gerbils have a rich repertoire of vocalization, with at least 13 distinct types of calls observed in a single colony. The purpose of this study was to compare the communicative value of these different call types in a standardized setting. Phonotactic behavior toward vocalizations delivered from loudspeakers was quantified by means of an eight-arm radial maze. Animals were observed to stay near the sound source for longer period of time when short bent-upward frequency-modulated (bUFM) calls, which are observed during seemingly friendly contact, were presented, while animals stayed significantly longer away from the speaker when arched FM (AFM) calls, which are produced by animals under severe physical stress, were presented. Our data show that an 8-arm radial maze can be used to study the function of Mongolian gerbil vocalization and suggest that both bUFM and AFM calls have communicative purposes, increasing the probability that recipient conspecifics approach or escape from the sound source, respectively.
