Mechanical features of ultrasound emission in the monogolian gerbil, Meriones Unguiculatus

Abstract

Ultrasonic emissions in gerbils are produced by body movements which force air through the larynx and out the nose. Social stimuli are necessary for their production, yet they do not seem to be oriented directly toward conspecifics. Much information could be contained in the physical parameters of the ultrasounds and their variation associated with body movements. © 1979 by the American Society of Zoologists.
