使用稳定同位素来深入了解个体的生活史是一个有价值的工具，无法识别或不完整的遗骸缺乏历史记录。这项研究分析了来自18 - 19世纪北美人的骨骼和牙齿的稳定碳、氮和氧同位素，这些人的祖先、社会阶层和原籍地区都是已知的，目的是辨别定性模式，并建立一个人口统计信息的定量预测模型。δ 13 C胶原、δ 13 C结构碳酸盐和δ 18 O结构碳酸盐值为检测人口统计学差异提供了最全面的信息，而δ 15 N胶原和δ 18 O磷酸盐的检测程度较低。来源地区是最可预测的人口因素，82%的正确分类基于一个双变量模型，使用δ 13 C胶原和δ 18 O大气降水计算的δ 18 O结构碳酸盐，这反映了当地的主要植被类型和当地饮用水的影响。用δ 13 C胶原蛋白正确鉴定的病例占68%。社会阶层的可预测性较低，在60%的情况下，根据δ 13 C、δ 15 N和δ 18 O值进行正确识别，其中上层阶级最容易区分。在祖先和社会阶层群体中观察到的同位素模式与文化食物偏好和食物供应有关。某些取样地点，如军事墓葬和城市墓地，显示出更大范围的同位素值，表明不同的个人区域起源和文化背景。埋葬的极端上层或下层阶级的个人表现出更大的同位素同质性，这表明依赖于当地的食物来源或文化偏好的特定饮食选择。
Using stable isotopes to gain insight into individual life histories is a valuable tool for unidentified or incomplete remains lacking historic records. This study analyzed stable carbon, nitrogen, and oxygen isotopes from bones and teeth of 18th–19thcentury North Americans of known ancestry, social class, and region of origin in an effort to discern qualitative patterns and create a quantitative predictive model of demographic information. The δ13Ccollagen, δ13Cstructural carbonate, and δ18Ostructural carbonatevalues provide the most overall information for detecting demographic differences, with δ15Ncollagenand δ18Ophosphateto a lesser degree. Region of origin was the most predictable demographic factor with 82% correct classifications based on a two-variable model using δ13Ccollagenand δ18Ometeoric watercalculated from δ18Ostructural carbonate, which reflects the influence of dominant local vegetation types and local drinking water. Ancestry was correctly identified in 68% of cases using δ13Ccollagen. Social class was less predictable with correct identification in 60% of cases based on δ13C, δ15N, and δ18O values where the upper class was most distinguishable. Isotope patterns observed in ancestry and social class groups are linked to cultural food preferences and food availability. Certain sample sites, such as military burials and urban cemeteries, show a greater range of isotope values suggesting a variety of individual regional origins and cultural backgrounds. Burials of extreme upper or lower class individuals show greater isotopic homogeneity suggesting reliance on localized food sources or cultural preferences for particular dietary choices.
