对晚更新世气候变化的适应是尼安德特人在欧亚大陆消失的一个经常被引用的潜在因素。因此，对尼安德特人行为的研究-包括生存策略、流动性、石器技术、原材料采购和人口统计-往往侧重于将考古记录中可观察到的变化与气候和环境变化的具体阶段联系起来。然而，这些对应关系往往是脆弱的，因为古气候和考古记录很少在同一规模上。在伊比利亚，一个了解尼安德特人死亡的关键地点，一些研究表明，尼安德特人无法从被称为海因里希事件的环境退化中恢复过来，而其他研究表明，尼安德特人的飞地在避难区存活了数千年。在这里，我们提出了一个palaeoenvironmental重建研究，使用三角洲C-13和三角洲O-18的草食动物牙齿釉质回收两个Mousterian存款在拉帕做皮卡雷罗，位于葡萄牙埃斯特雷马杜拉的网站。然后，我们使用这些数据，结合其他网站为基础的古环境指标，以评估葡萄牙中部是否充当避难所期间的不利气候，并测试尼安德特人在葡萄牙埃斯特雷马杜拉是否重组他们的流动性战略后，严重的气候事件。
Adaptation to Late Pleistocene climate change is an oft-cited potential contributor to Neanderthal disappearance in Eurasia. Accordingly, research on Neanderthal behaviour - including subsistence strategies, mobility, lithic technology, raw material procurement and demography - often focuses on linking changes observable in the archaeological record to specific phases of climate and environmental change. However, these correspondences are often tenuous because palaeoclimatic and archaeological records are rarely available on the same scale. In Iberia, a critical location for understanding the demise of Neanderthals, some research indicates that Neanderthal populations were unable to recover from environmental degradations known as Heinrich Events, while other studies suggest that enclaves of Neanderthal populations survived for several millennia longer in refugial zones. Here, we present a palaeoenvironmental reconstruction study using analysis of delta C-13 and delta O-18 of herbivore tooth enamel recovered from two Mousterian deposits at Lapa do Picareiro, a site located in Portuguese Estremadura. We then use these data, combined with other site-based palaeoenvironmental indicators, to assess whether central Portugal acted as a refugium during periods of unfavourable climate, and to test whether Neanderthals in Portuguese Estremadura reorganised their mobility strategies after severe climate episodes.
