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.

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心，不一定是研究者所在机构。研究野生侏儒狨猴发声交流和发声发育的种群差异。 很少有证据表明非人类灵长类动物的叫声具有声音可塑性。然而，在野生灵长类动物的声音交流的研究很少研究一个以上的人口，因此潜在的差异发声可能并不明显。我们正在研究厄瓜多尔东部亚马逊河上游盆地的五个侏儒绒猴种群。在校正个体差异后，我们发现每个种群的长音和颤音结构存在显著差异。这是第一个非供应猴子声音结构变异的证据（排除了人类干预作为变化来源）。我们还详细测量了环境噪声以及声音在每个栖息地中的退化情况，并发现叫声结构的一些差异可能与栖息地差异有关。我们还发现了用于分泌物喂养的树种的人口变化，可以反驳这种变化的几个生态假说，这表明社会学习可能占人口差异分泌物喂养的喜好。此外，我们正在研究幼年绒猴的“牙牙学语”，以了解更多关于声音发展的信息，我们正在研究捕食者的警报声。本研究使用WNPRC图书馆和信息服务。
