“…This is reflected in the stable isotope values of reindeer bone tissue, which is expected to be relatively low in nitrogen and high in carbon in reindeer feeding mostly on lichen (Britton 2009;Evans 2007, p. 85;Fjellström et al 2020). Based on the differences in the nitrogen and carbon values in the different foods the reindeer consume, these values may reflect differences in reindeer diet and possibly, human influences on it (Fjellström et al 2020;Salmi et al 2020a;Takken Beijersbergen et al 2021). In particular, it has been argued that especially relatively high values of nitrogen (δ 15 N) reflect foddering in the reindeer, as the replacement of low-nitrogen lichens in the winter diet with grasses, shrubs, and dried tree branches provided by humans would affect the stable isotope composition of the winter diet (Fjellström et al 2020;Salmi et al 2020a).…”

“…However, other factors that affect nitrogen values in reindeer bone, antler, and teeth, such as feeding in different environments (e.g., boreal forest vs. tundra), starvation, seasonal variations in antler shedding between the sexes, a young age (before weaning at ca. 6-7 months of age) (e.g., Barboza and Parker 2006;Parker et al 2005;Takken Beijersbergen et al 2021), and their effects must be considered when analyzing the stable isotope values of reindeer tissue samples.…”
