Appendix A (TABLE A1). ANOVA tables and unstandardized effect sizes based on differences in means and Tukey multiple comparisons of means with 95% family-wise confidence intervals (CI) for the three responses graphically represented in Fig. 2. Values presented are degrees of freedom (df), sum of squares (SS), mean squares (MS), F values, and P values.
