这项研究考察了雌性坎贝尔猴社会呼唤结构的变化。使用相似指数进行频率调制的比较显示，每个个体呈现一到三种变体。有些变体由两到几个人共享，通常与玩耍有关。相反，在社会孤立的动物中观察到声音分化，相似指数与回避频率呈负相关。这项初步研究首次提供了灵长类动物群体成员之间共享变异的证据。(C) 2003年中国科学院。由Elsevier SAS出版。版权所有。
This study examined variations of social call structures in female Campbell's monkeys. The comparison of frequency modulations using a similarity index revealed that each individual presented one to three variants. Some variants were shared by two to several individuals, often associated with play. On the contrary, vocal divergence was observed in a socially isolated animal and a negative correlation appeared between similarity index and the frequency of avoidance. This preliminary study gives the first evidence of variant sharing between group members in primates. (C) 2003 Academie des sciences. Published by Elsevier SAS. All rights reserved.
