Supplementary Table 1. One-way ANOVA testing the random effect of animal holding tank nested within treatment. from CO2-induced ocean acidification does not affect individual or group behaviour in a temperate damselfish

All parameters reported p-values above 0.25, a conservative significance level recommended by Quinn and Keough, 2002, and therefore removed tank as a random factor and the data pooled for analysis. Shaprio-Wilks test and Levene's test were used to assess the assumptions of normality and homoscedasticity, respectively.
