The formation of the “southern” paleolake in the place of the desalinated lagoon occurred ∼4060 cal yr BP, and the swamp began to develop ∼3370 cal yr BP, which coincides with the beginning of a prolonged period of droughts associated with a decrease in the intensity of the summer monsoon, cyclogenesis, and precipitation in the land-ocean marginal zone of the Asian-Pacific region.

Lake sediments are a significant carbon storage, as well as providing valuable archives for reconstructing long-term changes in soil erosion. The Tibetan-Yi Corridor, with its unique topography and rich history of human activity, is well suited to studies of human-environment interactions. This study analyzes sediment cores from two alpine lakes (Shayema and Xiaoshayema) in western Sichuan, China. Using AMS ¹⁴C dating and multi-proxy analyses, we reconstructed the history of enhanced anthropogenic soil erosion and its drivers in the corridor since the Ming and Qing dynasties. We show that military agriculture and timber harvesting during the Ming dynasty caused intermittent erosion in Shayema Lake's catchment. During the Qing Dynasty, large-scale human immigration and the introduction of new crops led to sustained and severe erosion in both basins. However, afforestation policies since the 1960s reduced erosion by promoting vegetation recovery. Compared with other lacustrine records from the Tibetan-Yi Corridor, anthropogenic erosion began earlier in the low-latitude Dianchi and Erhai Lake basins. From the Qin to Yuan dynasties, erosion expanded into low-elevation irrigated flatland areas undergoing rice cultivation. Ming-Qing immigration and the introduction of crops adapted to mountain environments further extended erosion to high-elevation areas. Lake organic carbon burial rates (OCBR) closely tracked sediment accumulation rates (SAR), with both increasing sharply during periods of intense erosion.

To enhance our understanding of current changes in diversity and its impact on ecosystem functions, knowledge of long-term interactions between vegetation diversity, land use change, and climatic change is crucial. Grid-cell estimates of quantified regional vegetation cover (RV_est) based on pollen data from 1607 sites across Europe, transformed using the REVEALS (Regional Vegetation Estimates from Large Sites) model, have been used to explore spatiotemporal changes in vegetation and regional diversity during the Holocene (25 time windows covering the period from 11.7 ka cal BP to present). Space-time constrained clustering of the RVests identified six dominant vegetation types (VTs): Mediterranean vegetation, open vegetation, <em>Abies-Fagus</em> forest, broadleaved mixed forest, coniferous mixed forest, <em>Betula</em> woodland, whose spatial extent changes over the Holocene. The study explored REVEALS α-diversity (richness of taxa, richness of abundant taxa, and evenness) within each grid cell as well as spatial REVEALS β-diversity (spatial variations in composition within one time frame) and turnover (temporal variation in composition within one grid cell) within each vegetation type. Changes in location, size, taxa composition, and REVEALS diversity of the vegetation types characterised four phases during the Holocene. The first (pioneer: 11.7–9.2 ka cal BP) and second (summer-green forest: 9.2 ka to 5.2 ka cal BP) phases generally showed higher REVEALS β-diversity and lower REVEALS evenness. The third phase (mixed semi-natural forest: 5.2 ka to 1.7 ka cal BP) is characterised by expansion of open vegetation and reflects increased human impact on the environment caused by increasing use of land for agricultural production. The final phase (from 1.7 ka cal BP) saw rapid transformations: open vegetation not only expanded, but also shifted in composition, with major increases in cereals and other anthropogenic indicators. This signals a clear intensification of land-use impact over the last two millennia. Across central Europe, vegetation became increasingly homogenised, dominated by a few widespread species.

We also integrate published zooarchaeological, archaeobotanical, and stable-isotope data from three different sub-regions of this transition zone to explore the interaction between introduced livestock and local millet agriculture—specifically, the dietary contribution of introduced animals to humans and the influence of local millet farming on livestock management. Our results indicate that: (1) at the Bronze Age Shuiquan site, in the Eastern part of the ecotone, humans primarily consumed millet crops (52 % ± 5 %), including foxtail and common millet. Animal protein was derived mainly from domestic omnivores, especially pigs and probably dogs (34.6 % ± 4.8 %), whereas introduced herbivores such as sheep and cattle contributed much less (10.8 % ± 3.1 %). In addition to provisioning pigs and dogs with millet, local inhabitants also kept cattle and a small number of sheep, feeding them millet by-products such as straw or chaff. (2) Regional comparisons across three sectors of the ecotone—Liaoxi, Hetao, and the Western Loess Plateau—show that millet remained the staple dietary source. However, in Hetao and the Western Loess Plateau, introduced herbivores (cattle, sheep) surpassed local omnivores (pigs, dogs) as the primary source of animal protein. Moreover, the contribution of millet to the diets of cattle and sheep exhibited a clear east-to-west decline.
