aMAE, model-averaged estimate averaged across the best supported set of models for that species (i.e. the cell with highest support in table 1), with back-transformed Wald 95% confidence intervals based on unconditional standard errors. The ratios of effects are taken from a combined OADA model for both species, including social transmission, sex and age, all of which were allowed to differ between species.
