Replication data for: Testing foraging optimization models in brown bears: Time for a paradigm shift in nutritional ecology?

This data contains two data files. One contains stable isotope ratios for indiviudally marked brown bears in a monitored population in Sweden from 1993 to 2020. The second file contains the stable isotope values for five common foods of brown bears; ants, moose (derived from hair), bilberry, crowberry, and lingonberry. The data and code were used to estimate the dietary proportions of each food source.
