Comparison of posterior distributions estimated from Bayesian stable isotope mixing models of proportional contribution of six prey species to diet of gray wolves in Northwestern Montana, USA, 2009.

Models were estimated with combinations of non-informative priors (N), informative priors (I), fox discrimination factors (F), and wolf discrimination factors (W). The three models represented in the table were compared to a fourth model (assumed to be closest to the true diet) specified with informative priors and gray wolf discrimination factors. Variance difference was calculated as the variance of each model subtracted by the variance of the fourth model.Comparison of posterior distributions estimated from Bayesian stable isotope mixing models of proportional contribution of six prey species to diet of gray wolves in Northwestern Montana, USA, 2009.
