Boxplots of fish biomass transect data during the pre-invasion (light blue boxplots) and post-invasion (orange boxplots) period for parrotfishes (a) and surgeonfishes (b) at 10 reefs (one panel per reef) representative of three reef types (B: bank; F: fringing; P: patch) during the fall, winter and summer seasons. All surveys involve ten 60 m2 transects except for Accra during the fall (n = 8) and winter (n = 9) seasons of the post-invasion period and Holetown during the winter of the pre-invasion period (n = 9). Data were standardized to 100 m2. Dashed vertical reference line represents the overall median transect value for the data pooled across all sites and surveys. Biomass values on the y-axis are shown on a fourth root transformed scale.
