Table 6 The difference in the magnitude of response to protection (ES DIFF ) between target-protected [TP] and non-target [NT] species for density data

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

  (a) All MPA case-studies included (N = 9) (b) Sensitivity analysis; habitat confounded studies excluded (N = 7)
  ES DIFF 95% CI Z-val p-val ES DIFF 95% CI Z-val p-val
rho = 0 −0.32 −0.72 → 0.08 −1.55 0.12 −0.09 −0.37 → 0.19 −0.64 0.52
rho = 0.5 −0.29 −0.69 → 0.11 −1.42 0.15 −0.08 −0.37 → 0.22 −0.52 0.60
rho = 1 −0.25 −0.56 → 0.06 −1.60 0.11 −0.03 −0.28 → 0.22 −0.23 0.82
  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 provided data for both categories and (b) for PPAs with no habitat confounded effect. N represents the number of PPAs included in the analysis.
