我们在这里报告了从哈桑凯夫霍伊菲克（底格里斯河谷上游新石器时代遗址）收集的人类和动物遗骸中各个氨基酸的稳定氮同位素组成（δ N-15）以及胶原蛋白的δ N-15 和δ C-13 含量。仅根据胶原蛋白的 Delta N-15，相对于陆地资源，很难清楚地确定淡水资源对狩猎采集者饮食的贡献。然而，对单个氨基酸的氮同位素组成的分析能够确定淡水资源对主要依赖陆地资源的社区的饮食的微小贡献。个体差异表明，哈桑凯夫霍伊菲克的一些个体使用淡水资源，而其他人可能主要依赖陆地食物资源。淡水资源作为狩猎采集社区食物的重要性因群体而异，并取决于埋葬地点和埋葬时间。 (C) 2017 Elsevier Ltd. 保留所有权利。
We report here the stable nitrogen isotope composition(delta N-15) of individual amino acids and the delta N-15 and delta C-13 content of collagen from human and faunal remains collected from Hasankeyf Hoyfik, an early Neolithic site in the upper Tigris valley. Based on the delta N-15 of collagen only, the contributions of freshwater resources to the diet of the hunter-gatherers were difficult to clearly identify relative to terrestrial resources. However, analysis of the nitrogen isotope composition of individual amino acids enabled the identification of minor contributions from freshwater resources to the diet in a community primarily dependent on terrestrial resources. Individual variability suggested that some individuals at Hasankeyf Hoyfik used freshwater resources, whereas others probably depended primarily on terrestrial food resources. The importance of freshwater resources as food for this hunter-gatherer community was variable among groups and depended on burial location and time of burial. (C) 2017 Elsevier Ltd.
