摘 要：In domestic dogs Canis familiaris,vocal traits have been investigated for barks and growls,and the relationship between individual body size and vocal traits investigated for growls,with less corre-sponding information for *** this study,we examined the frequency and temporal traits of whines of 20 adult companion dogs(9 males,11 females),ranging in body mass from 3.5 to 70.0 kg and belonging to 16 *** whines(26-71 per individual,824 in total)were recorded in condi-tioned begging contexts modeled by dog *** had 3 independent fundamental fre-quencies:the low,the high and the ultra-high that occurred singly as monophonic calls or simul-taneously as 2-voice biphonic or 3 voice polyphonic *** the smallest to largest dog,the upper frequency limit varied from 0.24 to 2.13 kHz for the low fundamental frequency,from 2.95 to 10.46 kHz for the high fundamental frequency and from 9.99 to 23.26 kHz for the ultra-high funda-mental *** individuals,the low fundamental frequency was lower in monophonic than in biphonic whines,whereas the high fundamental frequency did not differ between those whine *** frequency variables of the low,high,and ultra-high fundamental frequencies cor-related negatively with dog body *** duration,no correlation with body mass was *** discuss potential production mechanisms and sound sources for each fundamental frequency;point to the acoustic similarity between high-frequency dog whines and rodent ultrasonic calls and hypothesize that ultra-high fundamental frequencies function to allow private,tete-a-tetecom-munication between members of social groups.
