Abstract The presence of people in Switzerland in recently deglaciated landscapes after the Last Glacial Maximum represents human utilisation of newly available environments. Understanding these landscapes and the resources available to the people who exploited them is key to understanding not only Late Upper Palaeolithic settlement in Switzerland, but more broadly human behavioural ecology in newly inhabited environmental settings. By applying bone collagen stable isotope analysis (δ13C, δ15N and δ34S) to faunal remains from Late Upper Palaeolithic localities in Switzerland, we investigate animal ecology and environmental conditions during periods of human occupation. High and relatively uniform δ34S values indicate that landscapes north of the Jura Mountains provided comparatively stable environmental conditions, while lower and more variable δ34S values on the Swiss Plateau suggest a dynamic landscape with diverse hydrological and pedological conditions, potentially linked to regionally different patterns of permafrost thaw. This contrasts with the archaeological record that appears relatively uniform between the two regions, suggesting people were employing similar subsistence behaviours across a range of environmental settings. The pattern of change in δ15N across the deglacial period appears consistent between areas that remained ice-free throughout the LGM and those that were glaciated. Most notable is a period of exclusively low δ15N values between 15,200 and 14,800 cal. BP, which could relate a regional expansion of floral biomass in response to environmental change.

冰消期景观和瑞士旧石器时代晚期

摘要 在最后一次冰川盛期之后，瑞士人在最近冰川消退的景观中的存在代表了人类对新可用环境的利用。了解这些景观以及开发它们的人可用的资源不仅是了解瑞士旧石器时代晚期定居点的关键，也是了解新居住环境中更广泛的人类行为生态学的关键。通过将骨胶原稳定同位素分析（δ13C、δ15N 和 δ34S）应用于瑞士旧石器时代晚期晚期地区的动物群遗骸，我们调查了人类占领期间的动物生态和环境条件。δ34S 值较高且相对均匀，表明侏罗山脉以北的景观提供了相对稳定的环境条件，而瑞士高原较低且变化较大的 δ34S 值表明具有不同水文和土壤条件的动态景观，可能与区域不同的永久冻土融化模式有关。这与两个地区之间相对统一的考古记录形成对比，这表明人们在一系列环境设置中采用了类似的生存行为。整个冰消期期间 δ15N 的变化模式在整个 LGM 中保持无冰的区域和被冰川覆盖的区域之间似乎是一致的。最值得注意的是 δ15N 值在 15,200 到 14,800 卡路里之间的一段时期。BP，这可能与响应环境变化的花卉生物量区域扩张有关。
