  1. Results where different correlation coefficients (rho = 0, 0.2, 0.5, 0.8, 1) among individual species responses were used to compute the within-study sampling variance are given on separate rows. The LnRR ¯ and 95% CI are given for analysis using (a) all MPA case-studies, and (b) excluding MPAs with habitat confounded effects. N represents the number of MPAs for each exploitation category. Sample size for non-target species was inadequate for the analysis.
