Despite a long tradition of characterizing the Bell Beaker-associated human groups as mobile herders, there has been limited evidence for their economy and diet, both key defining factors for human lifeways. Bone nitrogen, carbon, and oxygen stable isotopes from a collective burial in Sardinia provide the first data on the diet of Mediterranean Bell Beaker groups, crucial as there is the presence of different domesticated species from the same context, thus enabling inferences on management practices. The data, evaluated in comparison with other groups, show high consumption of animal products and generalized, extensive livestock management, fitting the hypothesis of a relatively mobile lifestyle. Modeling of absolute dates and oxygen isotopic values suggest that the burials cover a period of fewer than two centuries, in which the group lived through a period of Rapid Climate Change, which overlaps with the 4.2 BP kya event previously recorded elsewhere in the Mediterranean, providing new elements for the understanding of demographic and cultural dynamics in the 3rd-millennium cal BC and more broadly emphasizing the role of climate in interpreting socio-cultural change.

了解快速气候变化与生存实践的交集：地中海 Bell Beaker 案例研究的同位素视角


尽管将贝尔·贝克 （Bell Beaker） 相关的人类群体描述为流动牧民有着悠久的传统，但关于他们的经济和饮食的证据有限，这两者都是人类生活方式的关键决定因素。来自撒丁岛集体埋葬的骨氮、碳和氧稳定同位素提供了关于地中海 Bell Beaker 群体饮食的第一个数据，这一点至关重要，因为存在来自相同环境的不同驯化物种，从而能够推断管理实践。与其他群体相比，数据显示动物产品的高消费量和普遍、粗放的牲畜管理，符合相对流动的生活方式的假设。绝对年代和氧同位素值的建模表明，这些墓葬跨越了不到两个世纪的时间，在此期间，该群体经历了一段快速的气候变化时期，这与之前在地中海其他地方记录的 4.2 BP kya 事件重叠，为理解公元前 3 世纪的人口和文化动态提供了新的元素，并更广泛地强调了气候在解释社会文化变化中的作用。
