Using Bone Collagen Stable Isotope Chemistry to Reconstruct Eastern Aleutian Paleo-Diets

这个项目，PI琼Coltrain，犹他州大学，是一个调查的饮食，环境压力和社会结构的更广泛的问题，通过分析前接触人口在阿留申群岛，阿拉斯加。 研究人员将通过对动物群遗骸的同位素分析，重建阿留申群岛两个区域分离的史前人口的饮食和生存方式。 PI希望不仅能阐明关于这两个群体之间差异的长期争论，而且还能阐明环境和社会结构的更大问题。

This project, PI Joan Coltrain, University of Utah, is an investigation of the broader issues of diet, environmental stress, and social structure through the analysis of pre-contact populations in the Aleutians, Alaska. The investigator will reconstruct the diets and subsistence practices of two regionally separated prehistoric populations in the Aleutians through isotopic analyses of faunal remains. The PI hopes to shed light not only on a long debate over the differences between these two populations but on larger questions of environment and social structure.
