Table 2.
Analysis of deviance. ANODEV is calculated as the difference in model deviance (−2logL) between the null model and the current model, divided by the difference between the null model and the full model. The incremental change in ANODEV contributed by submodels reflects the relative amount of residual variation explained by considering each predator species. Incremental deviance reported here reflects the difference between the current model and the habitat/prey model, thus reflecting the explanatory power of including (a) subordinate predator only, (b) top predator only, and (c) both subordinate and top predator
