Extended Data Fig. 8: Spatial pattern of commercial fish populations across MPA borders as a function of MPA age or size.
From: A meta-analysis reveals edge effects within marine protected areas
The separate effect of a, MPA age (young: age = < 10 years, 52 samples, n = 399; old: age >10 years, 56 samples, n = 594; ΔAICc = 7.7, DE = 57.7%), b, MPA size (small: size < 3 km2, 65 samples, n = 735; large: size > 3 km2, 43 samples, n = 258; ΔAICc = 5.9, DE = 57%). Young MPAs present shorter edge-effect distance compared to old MPAs, but with similar magnitude of population size reduction. Similarly, small MPAs present shorter edge-effect distance compared to large MPAs with similar magnitude of population size reduction. The analysis is restricted to the commercial fish dataset (containing 108 samples, n = 993) to avoid the confounding effect stemming from the spatial patterns associated with taxa identity and commercial value.
