Svalbard reindeer winter diets: Long-term dietary shifts to graminoids in response to a changing climate.

Of all the predictors in the selected models for both δ 13 C and δ 15 N, only population density and July average temperature showed a marked trend over the study period and are therefore driving some of the temporal trends in δ 13 C and δ 15 N. 4 DISCUSSION In this study, we sampled the serum of Svalbard reindeer between 1995 and 2012 to identify how the winter diets of a High Arctic herbivore have changed in response to long‐term climate trends and interannual variation, mostly depicted by the “normalization” of ROS events, increased summer temperatures and increased population density.
