Bronze Age sites in the coastal area of Sarrala, in Eastern Sardinia, have been subjected to survey and excavation over the last half-century. The study area, whose social and economic evolution and changing scales of interactions are traced through settlement patterns and building analysis, is interpreted in light of more general trends suggested by stable isotopes, archaeogenetics, and paleoclimatology. The local picture of progressive demographic growth and infilling of the landscape, with a subsequent concentration of population and labor, follows a sequence widely detected in Sardinia. More specific identifiable aspects include a comparatively higher fragmentation/competition (ratio of complex vs simple nuraghes; ratio of tombs vs nuraghes) and a consistent pattern in the distribution of non-local building materials in the latest phase at the sites showing archaic features, taken as a clue of a long-lasting authority at select sites. These elements are compatible with organized pastoral exploitation of the available territory, structured according to patrilocality and closeness to ancestral lineages and residences. The interplay of internal dynamics relative to constraints and opportunities is discussed, such as climate change and long-distance trade connections, with possible implications for interpreting Nuragic society.

青铜时代撒丁岛的社会组织、交叉点和互动。应用科学的贡献解读萨拉拉地区的聚落模式

在过去的半个世纪里，撒丁岛东部萨拉拉沿海地区的青铜时代遗址一直受到调查和挖掘。该研究区域的社会和经济演变以及相互作用的变化规模是通过聚落模式和建筑分析来追踪的，并根据稳定同位素、考古遗传学和古气候学提出的更普遍的趋势进行解释。当地人口的不断增长和景观的填充，以及随后的人口和劳动力的集中，遵循了撒丁岛广泛发现的序列。更具体的可识别方面包括相对较高的碎片化/竞争（复杂与简单努拉盖的比率；坟墓与努拉盖的比率）以及在显示古老特征的地点的最新阶段中非本地建筑材料分布的一致模式，采取作为选定站点的长期权威的线索。这些要素与对可用领土的有组织的牧业开发相一致，这些开发是根据父系和与祖先血统和居住地的密切程度而构建的。讨论了与限制和机遇相关的内部动态的相互作用，例如气候变化和长途贸易联系，以及对解释努拉吉社会的可能影响。
