Analysis of variance partitioning (ANOVA on linear additive models) of the effects of connectance, nestedness, mean specificity, and modularity, on strategy diversity, and the excess strategy diversity (deviation of empirical values from simulated networks as assessed by the Null Model analysis).

D: strategy diversity. Excess D: positive deviation of D under the assumptions of the null model. S: average specificity. NODF: nestedness. Q: modularity. Co: connectance. Bold predictors are significant.

Preliminary analyses showed no impact of the interaction type on these relationships, so this factor was not included as a covariate.
