High resolution dental casts can be used to document the pattern of dental microwear in museum specimens. The primary objective of this proposal is to document not only the pattern of wear, but its changes and rates over time in a live primate in the wild. Populations of a New World monkey, Alouatta palliata, which have been subject to behavioral observation for an extended period will be trapped and dental impressions taken. The resulting casts will be studied via scanning electronmicroscope for wear patterns and tooth morphology. Each animal will be re-cast several times during the course of the study, allowing for analysis of intra- individual change as a function of changing diet. This work will allow new insights into the association between diet and toothwear.

高分辨率的牙模可以用来记录牙齿的模式， 博物馆标本中的牙齿微磨损。 的主要目的 这项建议不仅要记录磨损的模式， 变化和速率随时间的变化。 新世界的猴子，Alouatta palliata， 长期接受行为观察， 被困住并进行牙齿印模。 产生的造型将 通过扫描电子显微镜研究磨损模式， 牙齿形态 每只动物都将被重新铸造几次 在研究过程中，允许分析内部， 个体变化是改变饮食的函数。 这项工作将 让我们对饮食和牙齿磨损之间的关系有了新的认识。
