From: Artificial reefs facilitate tropical fish at their range edge

Species richness (per 120 m2) of fishes on deep (18–25 m) artificial reefs versus natural reefs for (a) tropical, (b) subtropical, and (c) temperate climate ranges. Shaded areas of the violin plots are proportional to the number of observations. Points represent mean observed species richness (±1 SE)
