Extended Data Table 2 | Model predictions of time spent in predator chemical cue
Parameters (± standard error) and their statistical significance for general linear models that predict the mean percentage of time spent on the side of the choice flume containing the predator
chemical cue for an individual fish for six species of coral reef fishes tested in this study. We used backwards model selection using F-tests to compare the AIC of models with and without each
predictor variable using the ‘drop1’ function in R. Only the parameter estimates for the final (best) models are given, although we always kept the main effect of acclimation treatment (that is,
the effect of acclimation to elevated CO 2 ) in place because it was the key variable of interest. Note that for the D. perspicillatus model, the baseline factor level for size class was ‘early-stage
juveniles’ (<15 mm standard length). Sample sizes represent biologically independent animals. Statistical significance is indicated in bold (α = 0.05).
