Results of generalized linear mixed-effects models with binomial errors (floral fidelity and pollen deposition results) and negative binomial errors with zero-inflation (seed set results). For the “Manipulation” line, the model coefficient reports the difference moving from control to manipulated plots. *P < 0.05; **P < 0.01; ***P < 0.001.
