法国东南部Payre的旧石器时代中期遗址发现了大量与原始人类化石遗骸相关的考古材料。Payre具有较长的中更新世沉积层序，是研究该地区中旧石器时代年代学的重要地点。这项研究首次研究了尼安德特人牙釉质生物磷灰石的碳和氧同位素含量，以及广泛的草食性和肉食性物种。目的是通过古生态重建，促进对动物和尼安德特人的狩猎行为、资源分配、饮食和栖息地利用的理解。局部地形对草食动物牙釉质碳、氧稳定同位素值的影响较为明显。这被用来调查食草动物可能的栖息地。不同草食性物种的碳氧同位素值随时间变化不大，表明生态位在OIS 8-7 ~ OIS 6-5之间具有保守性，不受古气候和古环境变化的影响。基于这些新的观察结果，我们得出结论，尼安德特人长期以来采用稳定的生存策略，利用各种当地资源，在人类和食肉动物（尤其是狼）之间可以看到资源分配。稳定同位素研究结果与先前对同一牙齿进行的牙齿磨损分析结果的比较使我们能够证明，在同位素值中反映的C-3环境中，放牧和浏览不会将动物与特定的栖息地联系起来。(C) 2013 Elsevier Ltd.版权所有。
The Middle Palaeolithic site of Payre in southeastern France yields abundant archaeological material associated with fossil hominid remains. With its long sequence of Middle Pleistocene deposits, Payre is a key site to study the Middle Palaeolithic chronology of this region. This study is the first to investigate carbon and oxygen isotope contents of Neanderthal tooth enamel bioapatite, together with a wide range of herbivorous and carnivorous species. The aim is to contribute to the understanding of hunting behaviour, resource partitioning, diet and habitat use of animals and Neanderthals through a palaeoecological reconstruction. Local topography had a visible influence on carbon and oxygen stable isotope values recorded in herbivore tooth enamel. This was used to investigate possible habitats of herbivores. The different herbivorous species do not show large variations of their carbon and oxygen isotope values through time, indicating niche conservatism from OIS 8-7 to OIS 6-5, i.e., independently of palaeoclimatic and palaeoenvironmental variations. Based on these new observations, we conclude that Neanderthals employed a stable subsistence strategy over time, using a variety of local resources, with resource partitioning visible between humans and carnivores, especially wolves. A comparison of the results of stable isotopic investigation with the results of tooth wear analyses previously conducted on the same teeth allowed us to demonstrate that grazing and browsing do not bind animals to a specific habitat in a C-3 environment as reflected in the isotopic values.
