Fig. 4 — Estimated contributions (%) of food sources to maternal diets were determined using a five-source (bison, wapiti, small game, salmon, and whitefish), two-biotracer (δ¹³C_collagen and δ¹⁵N_collagen) mixing model in MixSIAR. Terrestrial is an a posteriori aggregation of bison, wapiti, and small game. (A) Box plots showing median (center line), 50% credible interval (CI) (box edges), and 95% CI (error bars) for estimated contributions. (B) Posterior distributions (colored) superimposed on prior distributions (gray) of source contributions for USR1 (darker color) and USR2 (lighter color). Prior is the uninformative Dirichlet (equal weights for all five original sources).
