Correction to: Archaeological and Anthropological Sciences https://doi.org/10.1007/s12520-018-0660-4 As part of our paper we evaluated differences between stable isotope ratios of geographic units as well as between livestock taxa. We incorrectly used ANCOVA (analysis of covariance) when we should have used ANOVA (analysis of variance) which compares variation between groups. We have reanalysed all of the datasets and found that the significance of our results changed slightly, leading to an increase in significant differences between groups (see bold text). However, our overall discussion has not changed and these findings offer further support for our previous conclusions. Results The floral base of the food web Bestamak: Significant differences were identified in average δ15N values between all units at the site of Bestamak (ANOVA, p = 1.45 ×
10−11; Correction Supplemental Table 3). Units were then combined into three vegetation communities including the open steppe (OS), areas of anthropogenic activity (AA) and riverine, salt lake, and marsh (RSL). Significant differences in δ15N values were identified between the plants in the open steppe and those in areas of anthropogenic activity and near water (ANOVA, p = 1.45 × 10−11; Correction Supplemental Table 3). No statistically significant isotopic variation was evident in carbon isotope values between units or vegetation communities (Correction Supplemental Table 3). Lisakovsk: Isotopic variation between collection units at Lisakovsk (n = 4) indicates that significant differences were identified in average δ15N values between unit 5013 and the other units (ANOVA, p = 5.43 × 10─6) and statistically significant isotopic variation was evident in carbon isotope values (ANOVA, p = 0.04; Correction Supplemental Table 3). Unit 5013 has a significantly lower average nitrogen isotope composition than other units by 3.2‰ (Correction Supplemental Table 3).
