Fig. 5: Data graph of carbon and nitrogen stable isotopes of plants, animals, and human bones, as well as animal and plant remains from the 4200BP site in the desert loess transition zone.
From: Multi-proxy investigations of subsistence strategy during Bronze Age in Inner Mongolia, China
a Plant remains excavated from sites in the loess-desert transition zone: 1. Shimao 2. Bicun 3. Zhaimao 4. Zhaimaoliang 5. Hengshan 6. Sharitala 7. Dakou 8. Yadi 9. Zhukaigou 10. Shangyuan 11. Shangshen 12. Shengedaliang 13. Jijiazhuang 14. Muzhuzhuliang 15. Xinzhang 16. Huoshiliang (see Supplementary Material Table 3 for details). b Percentage of animal remains in the loess-desert transition zone area: P: Pig, C: Cattle, S: Sheep/goat, W: Wild animals(see Supplementary Material Table 5 for details). c Isotopic data from millet at sites in the loess-desert transition zone(see Supplementary Material Table 4 for details). c-1 The scattered points represent the δ15N values of the plants, and the upper and lower edges of the black box plot indicate the boundaries of the 95% confidence interval range of the data, and black points are the mean value. c-2, c-3 Error bars represent 95% confidence intervals. d Box-plot of isotopic data from animals at sites in the loess-desert transition zone(see Supplementary Material Table 4 for details). The upper and lower edges of the black box plot indicate the boundaries of the 95% confidence interval range of the data, and black points are the mean value. e Box-plot of isotopic data from humans at sites in the loess-desert transition zone: 1. Shimao 2. Bicun 3. Sharitala 4. Dakou 5. Shengedaliang 6. Muzhuzhuliang 7. Jijiazhuang 8. Xinzhang(see Supplementary Material Table 4 for details).
