Table B1. Candidate models of Maieta guianensis demographic functions and the results of model fitting. ΔAICc values indicate the difference between the best fit model (in bold) and the alternative model. We used the best-fit model in all cases except for fruit production in partner-switching populations, in which diagnostic tools to assess suitability of the IPMs indicated the alternative model was superior for IPM construction. We felt this was acceptable given the very low ΔAICc value in this case.
