Central European forests have been shaped by complex human interactions throughout the Holocene, with significant changes following the introduction of domesticated animals in the Neolithic (∼7.5-6.0 ka before present [BP]). However, understanding early pastoral practices and their impact on forests is limited by methods for detecting animal movement across past landscapes. Here, we examine ancient sedimentary DNA (sedaDNA) preserved at the Velký Mamuťák rock shelter in northern Bohemia (Czech Republic), which has been a forested enclave since the early Holocene. We find that domesticated animals, their associated microbiomes, and plants potentially gathered for fodder have clear representation by the Late Neolithic, around 6.0 ka BP, and persist throughout the Bronze Age into recent times. We identify a change in dominant grazing species from sheep to pigs in the Bronze Age (∼4.1-3.0 ka BP) and interpret the impact this had in the mid-Holocene retrogressions that still define the structure of Central European forests today. This study highlights the ability of ancient metagenomics to bridge archaeological and paleoecological methods and provide an enhanced perspective on the roots of the "Anthropocene."
中欧森林在整个全新世都受到人类复杂相互作用的影响,在新石器时代(约公元前 7500 年至 6000 年)引入驯化动物后发生了重大变化。然而,理解早期的放牧实践及其对森林的影响受到了在过去景观中检测动物运动的方法的限制。在这里,我们研究了保存在捷克北部 Velký Mamuťák 岩棚中的古代沉积 DNA(sedaDNA),自全新世早期以来,这里一直是一片森林飞地。我们发现,驯化动物及其相关微生物组,以及可能为饲料收集的植物,在公元前 6000 年左右的新石器时代晚期就有明确的代表,并一直持续到青铜时代直至近代。我们发现,在青铜时代(公元前 4100 年至 3000 年),主要的放牧物种从绵羊变为了猪,并解释了这对当今仍定义着中欧森林结构的中全新世后退的影响。这项研究强调了古代宏基因组学在连接考古学和古生态学方法方面的能力,并提供了对“人类世”根源的更深入了解。
