Encoding of Arousal and Physical Characteristics in Audible and Ultrasonic Vocalizations of Mongolian Gerbil Pups Testing Common Rules for Mammals

ABSTRACT:

Simple Summary

Mammals provide information about their emotional state and physical characteristics through vocal signals. Due to a similar vocal production apparatus across mammals, common rules for encoding this information are proposed. With increasing age/body weight, it is suggested that mammals utter elongated calls of lower frequency. With increasing arousal, it is proposed that mammal vocalizations become higher in frequency and longer in duration. However, in recent years an increasing number of mammalian species have showed discrepancies with these common rules. In this study, we investigated whether developing Mongolian gerbil pups fulfill the proposed common rules by recording vocalizations in a low and high arousal condition in four age groups. We discovered they prod
