Fremont societies of the Uinta Basin incorporated domesticates into a foraging lifeway over a 1,000-year period from AD 300 to 1300. Fremont research provides a unique opportunity to critically examine the social and ecological processes behind the adoption and abandonment of domesticates by hunter-gatherers. We develop and integrate a 2,115-year precipitation reconstruction with a Bayesian chronological model for the growth of Fremont societies in the Cub Creek reach of Dinosaur National Monument. Comparison of the archaeological chronology with the precipitation record suggests that the florescence of Fremont societies was an adaptation to multidecadal precipitation variability with an approximately 30-plus-year periodicity over most, but not all, of the last 2,115 years. Fremont societies adopted domesticates to enhance their resilience to periodic droughts. We propose that reduced precipitation variability from AD 750 to AD 1050, superimposed over consistent mean precipitation availability, was the tipping point that increased maize production, initiated agricultural intensification, and resulted in increased population and development of pithouse communities. Our study develops a multidecadal/multigenerational model within which to evaluate the strategies underwriting the adoption of domesticates by foragers, the formation of Fremont communities, and the inherent vulnerabilities to resource intensification that implicate the eventual dissolution of those communities.

犹他州东部弗里蒙特社会的多年气候变率和花期

从公元 300 年到 1300 年的 1000 年间,乌因塔盆地的弗里蒙特社会将驯养纳入了觅食生活方式。弗里蒙特研究提供了一个独特的机会,可以批判性地研究狩猎采集者采用和放弃驯养背后的社会和生态过程。我们开发并整合了 2,115 年降水重建与贝叶斯年代顺序模型,用于恐龙国家纪念碑 Cub Creek 河段弗里蒙特社会的增长。考古年代学与降水记录的比较表明,弗里蒙特社会的花期适应了几十年的降水变化,在过去 2,115 年的大部分时间(但不是全部)中具有大约 30 多年的周期性。弗里蒙特社会采用驯养动物来增强他们对周期性干旱的抵御能力。我们认为,从公元 750 年到公元 1050 年,降水变化的减少,叠加在一致的平均降水可用性之上,是增加玉米产量、启动农业集约化并导致人口增加和坑舍社区发展的临界点。我们的研究开发了一个多年代/多代模型,在该模型中评估为采食者采用驯化动物、弗里蒙特社区的形成以及资源集约化的内在脆弱性提供保障的策略,这些脆弱性意味着这些社区的最终解体。叠加在一致的平均可用降水量之上,是增加玉米产量、启动农业集约化并导致人口增加和坑舍社区发展的临界点。我们的研究开发了一个多年代/多代模型,在该模型中评估为采食者采用驯化动物、弗里蒙特社区的形成以及资源集约化的内在脆弱性提供保障的策略,这些脆弱性意味着这些社区的最终解体。叠加在一致的平均可用降水量之上,是增加玉米产量、启动农业集约化并导致人口增加和坑舍社区发展的临界点。我们的研究开发了一个多年代/多代模型,在该模型中评估为采食者采用驯化动物、弗里蒙特社区的形成以及资源集约化的内在脆弱性提供保障的策略,这些脆弱性意味着这些社区的最终解体。
