Fig. 2: Overall ecological effect of MAS.
From: A global meta-analysis of ecological effects from offshore marine artificial structures
The overall meta-analytic model shows significant moderate positive effects of MAS on marine ecosystems compared with sites without structures present (t108 = 3.7249, P = 0.0003). a, Visualized using an orchaRd plot. Individual effect sizes from studies are represented as grey bubbles. The dot represents the estimated mean Hedges’ g value 0.47. The bold error bars represent the 95% confidence interval (95% CI 0.22, 0.73). The thin error bars represent the 95% prediction interval. Please note that the CI around the mean is very small in this instance. b, Visualized using a caterpillar plot. The estimated mean Hedges’ g value is depicted at the bottom in red. Individual effect sizes are ordered by magnitude and each individual effect size is depicted by a yellow dot with green 95% CI bars. Based on 531 effect sizes from 109 articles.
