5.4 Diet and mobility

Dietary life history data was available for the majority of the Resmo individuals. Based on individual ranges of δ13C and δ15N, their dietary variation was classified as limited, moderate and pronounced, respectively (Eriksson et al. 2008; Eriksson and Lidén 2013). Evidently, four individuals experienced changes in residence not accompanied by any major shifts in diet: subjects 2 and 10 in Phase 1, and subjects 13 and 23 in Phase 3. Five individuals have changed residence while also markedly changing diet (moderate or pronounced dietary variation): subjects 12, 16, 19 and 21 in Phase 2, and subject 18 in Phase 3. Of the twelve individuals for whom no change of residence was discernible, only one, subject 8 in Phase 1, had any notable dietary variation, while the remaining eleven individuals had limited dietary variation: subjects 1 and 6 in Phase 1, subjects 3, 15 and 20 in Phase 2, and subjects 17, 24, 26, 27, 28 and 30 in Phase 3. Consequently, it seems that major shifts in diet could be explained primarily by change of residence.
