Table 7 The difference in the magnitude of response to protection (ES DIFF ) between target-protected and non-target species for biomass data

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

  (a) All MPA case-studies included (N = 6) (b) Sensitivity analysis; habitat confounded studies excluded (N = 5)
  ES DIFF 95% CI Z-val p-val ES DIFF 95% CI Z-val p-val
rho = 0 0.04 −0.56 → 0.64 0.13 0.89 0.008 −0.67 → 0.69 0.02 0.98
rho = 0.5 0.13 −0.48 → 0.74 0.41 0.67 0.10 −0.60 → 0.80 0.27 0.79
rho = 1 0.19 −0.15 → 0.53 1.09 0.27 0.16 −0.23 → 0.55 0.81 0.42
  1. Studies were weighted by the variance of the difference between two correlated variables (correlation coefficients of rho = 0, 0.5, 1). The ESDIFF, 95% confidence interval, Z-val and p-val are given for (a) all PPA case-studies that provide data for both categories and (b) for PPAs with no habitat confounded effect. N represents the number of PPAs included in the analysis.
