“…After AD 1350, increased communication with central China along with the improvement of agricultural technology following the setup of Yunnan province resulted in further intensified human activities (You, 1994). Further evidence was gained from the abundances of non-pollen polymorphs (NPPs), as well as fern spores and algae, which have been widely investigated in terms of anthropogenic environment changes (Ge et al, 2019; Zhang et al, 2020; Zhao et al, 2017). Ferns could expand significantly after forest clearance, resulting in overwhelming increase of fern spores in the sediment, particularly Microlepia and Athyrium (Xie et al, 2008; Yang et al, 1998; Zhao et al, 2017).…”

Understanding long-term vegetation diversity patterns and their potential responses to climate and/or human driven processes are important for ecosystem modeling and conservation. Late-Holocene fossil pollen assemblage and associated vegetation diversity estimates provide an opportunity to explore the interactions among vegetation, climate, and human activities. A continuous 2000-year palynological record was obtained from the Beihai Wetland, southwestern China, to represent regional vegetation history, particularly the vegetation diversity changes. The results indicate that regional vegetation was dominated by deciduous broadleaved forest components (e.g. Alnus, deciduous Quercus), which showed a gradual decrease accompanied by expansion of herbaceous taxa (mainly Poaceae) after AD 800. Such progressive decline of forest was attributed to regional deforestation driven by intensified human activities, which was further confirmed by the increasing non-pollen polymorph abundance, particularly an abrupt rise after AD 1350. Vegetation diversity based on the Hill numbers ( N0, N1, and N2) showed a dramatic decline between ca. AD 200–400, which was triggered by regional fire events as shown by increased charcoal abundance from a nearby lake. The vegetation diversity reduced gradually after AD 800, especially the vegetation richness reflected by N0, revealing the transitional process from climate-driven to human-dominated vegetation changes. Minor increases of vegetation diversity occurred during Chinese dynastical transitions, probably due to reduced human activities following war-induced population crises. On the multidecadal scale, variations in vegetation diversity correlated significantly with climate fluctuations (revealed by synthesized temperature of China and stable oxygen isotope record from Dongge Cave) before AD 800, indicating a climate dominant condition. Then, the correlation between vegetation diversity and climate declined after AD 800, representing a progressive transition to human-dominant condition. In addition, the compositional turnover based on DCCA of the fossil pollen assemblage revealed a stepwise decrease, indicating reduced vegetation turnovers under anthropogenic influences.

“…High abundance of cholesterol, one of the animal derived biomarkers, supports the identification of bone in the residue crust. Zhang et al (2020) revealed much more long‐chain (>C24) n‐alkanols and n‐FAs in the environmental soils of layer 7 (7000–6500 BP) at Tianluoshan site than those detected from the crusts in the Hemudu bo bowls. These soil samples, given their contemporaneity with the phase I of Hemudu, provide important background lipid composition in the nearby area.…”

Here, we report the results of residue analyses of crusts in pottery bowls from early phases of the Hemudu archaeological site (~7000–6000 BP), China, through a multi‐disciplinary approach. The physical morphology and chemical composition of the residues were examined via multiple analytical techniques, including EPMA, FTIR, SEM‐EDS, GC and microscopic observation. The elemental composition of the residues consistently comprise C, O, P and Ca. FTIR spectra of residues are also very similar to each other and have spectral bands consistent with CHAp spectra. SEM‐EDS tests provide clear morphological features of the bone particles and in situ elemental information. Fatty acid analysis further suggests an origin of residues is likely to be from terrestrial vertebrate bones. Analysis of starch granules, also recovered from the crusts, indicates Cyclobalanopsis sp. acorns. We demonstrate that the crusts are the remains of a special mixture of bone meal and acorn starch. This usage of bone resources is previously unknown in the Chinese Neolithic and may have served various functions, including a medicinal, a food supplement to manage dietary stress, or a special diet for children. Our findings enrich the understanding of prehistoric usage of bone meal, as well as the subsistence strategies of the Middle Neolithic Hemudu people, who were engaged in increasingly intensified rice agriculture in the lower Yangzi River region.
