Table 3. Process-only trends differences (mean ±SD) for pre- to post-treatment ecological group measures at Quincy Bluff and Wetlands Natural Area. Bias-adjusted effect size, 95% confidence interval of effect size, and F-values and probabilities for analysis-of-variance (ANOVA) tests are reported. ANOVA models tested main effects of the structural manipulation treatment (n = 12) against the control (n = 10). Significance values of tests are indicated in bold at P < 0.05, whereas marginal significance values (P < 0.10) are in italics.
