Table 11 The summary effect size LnRR ¯ and [95% CI] based on biomass data for target-protected [TP] and target-not protected [TNP] exploitation categories, weighted by sampling variances

From: Evaluating the biological effectiveness of fully and partially protected marine areas

  (a) All MPA case-studies included (b) Sensitivity analysis; habitat confounded studies excluded
  Target - protected Target - non-protected Non-target Target - protected Target - non-protected Non-target

  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.
