Basal sections of whiskers from 90 Tasmanian devils were analyzed for δ13C and δ15N. The table summarizes the top model set for each general linear model of variation in δ13C and δ15N, where top models sets were restricted to models with ΔAICc < 2. Effect sizes are reported for retained variables in each model. Relative variable importance (RVI) is shown for δ15N as multiple models had ΔAICc < 2.
