Abstract Multi-isotope analyses on diverse body tissues can offer valuable information on individual life-histories at different temporal resolutions. Here, we reconstruct the diet and mobility of a Late Mesolithic (ca. 5500 cal. BC) young woman buried in Aizpea rockshelter (Navarre, north-central Iberia). To this end, we combine δ13C and δ15N isotope analyses of bone collagen, together with sequential δ13C and δ15N isotope analyses of tooth dentine and 87Sr/86Sr analysis of tooth enamel from the permanent maxillary right second molar. We also present results of bone collagen measurements for a wide range of coeval faunal remains, including terrestrial ungulates, freshwater fish and birds, and plant remains (i.e. carbonized pome fruits and hazelnut shells) to characterize baseline isotopic signatures. Results suggest a broad-spectrum diet with a relatively high and stable protein intake during early childhood and significant changes in diet during late childhood, including two marked dips in δ15N at 8.5 and 11.5 years old, and a progressive decrease in δ13C and δ15N from adolescence onwards. The dips may relate to metabolic processes related to growth or, more probably, to age-related subsistence practices, particularly supplementation by children of the parentally provisioned diet, while the sustained drop in isotope values may be associated with a progressively higher dietary contribution from plants that extends into adulthood. Strontium isotope data support relatively restricted mobility from age 2.5 to 8 (i.e. the approximate time-span covered by enamel formation in the permanent maxillary second molar), consistent with the high degree of territoriality attributed to the last hunters-gatherers in northern Iberia.

伊比利亚中石器时代晚期妇女的生活史：连续多同位素方法

摘要 对不同身体组织的多同位素分析可以在不同时间分辨率下提供有关个体生命史的宝贵信息。在这里，我们重建了一位埋在 Aizpea 岩石避难所（纳瓦拉，伊比利亚中北部）的中石器时代晚期（约公元前 5500 卡路里）年轻女性的饮食和活动。为此，我们结合了骨胶原的 δ13C 和 δ15N 同位素分析，以及牙齿牙本质的连续 δ13C 和 δ15N 同位素分析以及来自上颌右侧第二磨牙的牙釉质的 87Sr/86Sr 分析。我们还提供了范围广泛的同时代动物遗骸的骨胶原测量结果，包括陆生有蹄类动物、淡水鱼和鸟类，以及植物遗骸（即碳化的梨果和榛子壳），以表征基线同位素特征。结果表明，儿童早期采用广谱饮食，蛋白质摄入量相对较高且稳定，儿童晚期饮食发生显着变化，包括 8.5 和 11.5 岁时 δ15N 两次显着下降，以及 δ13C 和 δ15N 从青春期开始逐渐减少向前。下降可能与与生长有关的代谢过程有关，或者更可能与与年龄相关的生存实践有关，特别是由父母提供的饮食的儿童补充，而同位素值的持续下降可能与植物对饮食的贡献逐渐增加有关这延伸到成年。锶同位素数据支持从 2.5 岁到 8 岁的相对受限的流动性（即上颌第二磨牙牙釉质形成所涵盖的大致时间跨度），
