这是首次对黑冠长臂猿雄性鸣叫声的个体性进行研究。声音记录在两个现场进行，平和，哀牢山，大寨子，无量山，都位于中国云南省。共分析了8只雄性长臂猿38次鸣叫的127个尾段。逐步判别函数分析被用来检查男性的声学个性。我们发现邻居之间的个性非常明显。此外，一个站点内（即邻居之间）的个体性高于站点之间的个体性。我们的研究结果表明，黑冠长臂猿可能会积极增加他们的程度，对他们的直接邻居的声音调整的声音个性。Am. J. Primatol. 73：431-438，2011.© 2010 Wiley利斯公司
This is the first study of vocal individuality in male songs of black crested gibbons. The sound recordings were carried out at two field sites, Pinghe, Ailao Mountains, and Dazhaizi, Wuliang Mountains, both located in Yunnan province, China. A total of 127 coda phrases of 38 male songs bouts of eight individual male gibbons were analyzed. Stepwise discriminant function analysis was used to examine the acoustic individuality of the males. We found that individuality among neighbors was very pronounced. Moreover, individuality within a site (i.e. among neighbors) is higher than among individuals between sites. Our finding suggests that black crested gibbons may actively increase their degree of vocal individuality against that of their immediate neighbors by vocal adjustment. Am. J.
