Overall effects and heterogeneity in the mean difference of reef-associated fishes and habitat structure among zones of the Saba Marine Park.

Spanning five surveys (1991, 1993, 1994, 1995, 2008) at two depths (5 and 15 meters) among zones closed and open to fishing, the significant p-values for overall effect of zoning (Z, df = 4, α = 0.0125, after Bonferroni correction for multiple comparisons, k = 5) and variability across survey years (χ2, df = 4, α = 0.10, [40]) are indicated in bold. Underlying data for 1991–95 sourced from Polunin and Roberts [22], Roberts [23] and Roberts and Hawkins [24].
