目的：Ostorf（德国）的岛屿墓地遗址由包含漏斗烧杯陶瓷的个体人类坟墓组成，这些陶瓷可以追溯到新石器时代早期或中期。然而，之前的同位素和放射性碳分析表明，Ostorf个体的饮食中含有丰富的淡水鱼。本研究旨在定量重建Ostorf人群的饮食，并确定饮食习惯是否与新石器时代饮食的传统特征相一致。方法采用贝叶斯混合模型“基于同位素传递信号的食物重建”（FRUITS）来模拟多种饮食代用物（C-13（胶原）、N-15（胶原）、C-13（生物磷灰石）、S-34（蛋氨酸）、C-14（胶原））的同位素测量，通过这种新方法实现定量饮食重建。通过比较观测到的和估计的人类膳食放射性碳库效应之间的一致性，验证了模型估计的准确性。结果定量的饮食重建估计证实，由于食用鱼类和陆生动物产品，Ostorf个体具有较高的蛋白质摄入量。然而，fruit估计也表明植物性食物是卡路里的重要来源。以Ostorf湖的水生水库效应为参照，人类膳食放射性碳水库效应的观测值和估计值基本一致。Ostorf种群显然采用了与新石器文化相关的元素，但适应了现有的当地食物资源，并实施了一种包括大量鱼类和陆生肉类消费的生存策略。这个案例研究体现了新石器时代生存策略的多样性。[J] .中国生物医学工程学报，2015,31(2):357 - 357。(c) 2015 Wiley期刊公司
ObjectivesThe island cemetery site of Ostorf (Germany) consists of individual human graves containing Funnel Beaker ceramics dating to the Early or Middle Neolithic. However, previous isotope and radiocarbon analysis demonstrated that the Ostorf individuals had a diet rich in freshwater fish. The present study was undertaken to quantitatively reconstruct the diet of the Ostorf population and establish if dietary habits are consistent with the traditional characterization of a Neolithic diet.MethodsQuantitative diet reconstruction was achieved through a novel approach consisting of the use of the Bayesian mixing model Food Reconstruction Using Isotopic Transferred Signals (FRUITS) to model isotope measurements from multiple dietary proxies (C-13(collagen), N-15(collagen), C-13(bioapatite), S-34(methione), C-14(collagen)). The accuracy of model estimates was verified by comparing the agreement between observed and estimated human dietary radiocarbon reservoir effects.ResultsQuantitative diet reconstruction estimates confirm that the Ostorf individuals had a high protein intake due to the consumption of fish and terrestrial animal products. However, FRUITS estimates also show that plant foods represented a significant source of calories. Observed and estimated human dietary radiocarbon reservoir effects are in good agreement provided that the aquatic reservoir effect at Lake Ostorf is taken as reference.ConclusionsThe Ostorf population apparently adopted elements associated with a Neolithic culture but adapted to available local food resources and implemented a subsistence strategy that involved a large proportion of fish and terrestrial meat consumption. This case study exemplifies the diversity of subsistence strategies followed during the Neolithic. Am J Phys Anthropol 158:325-340, 2015. (c) 2015 Wiley Periodicals, Inc.
