The western Henan Province constitutes the core area of Yangshao Culture. To investigate the dietary conditions of the early Yangshao ancestors in this area, analysis of plant micro-remains (starch grains and phytoliths) and organic acid residues was conducted on 34 pottery samples unearthed at the Chengyan Site in Lingbao City, western Henan Province, central China. The results revealed that the plant foods of the Chengyan people included Triticeae, Job's tears (<em>Coix lacryma-jobi</em>), rice (<em>Oryza sativa</em>), millet (<em>Setaria italica</em> and <em>Panicum miliaceum</em>), lotus root <em>(Nelumbo nucifera</em>), snake gourd root (<em>Trichosanthes kirilowii</em>), yam (<em>Dioscorea</em>), lily (<em>Lilium brownii</em>), legumes (Fabaceae), and acorn (<em>Quercus</em>), in which, some species served as raw materials for brewing fermented beverages. These findings demonstrate that botanical resource exploitation during this period in central China exhibited remarkable diversity, with foraging maintaining its significance as an essential subsistence strategy for early human populations in acquiring plant foods. The presence of rice at the Chengyan site indicates its spread to western Henan during the early Yangshao period, and a rice-millet mixed farming, dominated by foxtail millet and broomcorn millet, had developed in the area.

The stratigraphic record from the Punta de s'Avançada outcrop in North Mallorca provides valuable insights into the paleoenvironmental changes driven by Heinrich (HE) and Dansgaard-Oeschger (DO) events during the late Pleistocene. Detailed analysis of six distinct sedimentary units (U1-U6) reveals the significant impact of abrupt climatic shifts on sediment supply, depositional environments, and sea-level fluctuations. The cold, arid conditions during HE events, particularly H4 and H5, promoted extensive dune formation in Units U4 and U6, while the warmer, wetter conditions during DO events facilitated alluvial and colluvial deposition in Units U1 and U5. By integrating OSL dating with climatic oscillations, this study demonstrates the influence of millennial-scale HE and DO events on sedimentary processes in coastal landscapes of the western Mediterranean.

The landscape stability resulting from the river incision facilitated early urbanization and the expansion of urban areas.

The three-dimensional descriptive model reproduces changes in local faunal (LF) composition caused by the general climate trend during the transition from interstadial conditions at the end of MIS3 to the extremely cold conditions of the LGM (mid-MIS2).
