This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. To study population differences in vocal communication and vocal development in wild pygmy marmosets. There has been little evidence of vocal plasticity in calls of nonhuman primates. However, studies of vocal communication in wild primates have rarely studied more than one population and thus potential differences in vocalization may not be evident. We are studying five populations of pygmy marmosets in the upper Amazon basin in Eastern Ecuador. We have found significant differences in the structure of long -calls, and trills in each population, after correcting for individual differences. This is the first evidence of variability in vocal structure in non-provisioned monkeys (ruling out human intervention as a source of change). We have also made detailed measurements of environmental noise and how sounds are degraded in each of the habitats and find some of the differences in call structure can be related to habitat differences. We have also found population variation in the species of trees used for exudate feeding and can refute several ecological hypotheses for this variation, suggesting that social learning may account for population differences in exudate feeding preferences. In addition we are studying the "babbling" of young infant marmosets to learn more about vocal development, and we are studying predator alarm calls.

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。目的研究野生侏儒绒猴发声交流和发声发育的种群差异。非人灵长类动物的叫声几乎没有可塑性的证据。然而，对野生灵长类动物发声交流的研究很少研究一个以上的种群，因此发声的潜在差异可能并不明显。我们正在研究厄瓜多尔东部亚马孙盆地上游的五种侏儒绒猴。我们发现，在校正了个体差异后，每个群体的长鸣和颤音的结构存在显著差异。这是第一次有证据表明，非自给性猴子的发声结构存在变异性(排除了人类干预作为改变的来源)。我们还对每个栖息地的环境噪音和声音如何退化进行了详细的测量，发现呼叫结构的一些差异可能与栖息地的差异有关。我们还发现了用于分泌物喂养的树木物种的种群差异，并可以驳斥这种差异的几个生态学假说，表明社会学习可能解释了渗出物喂养偏好的种群差异。此外，我们正在研究幼龄绒猴的“叽叽喳喳”，以了解更多关于声音发育的知识，我们正在研究捕食者的警报叫声。这项研究使用了WNPRC图书馆和信息服务。
