From: Artificial reefs facilitate tropical fish at their range edge
Abundance (per 120 m2) of fish trophic groups on deep (18–25 m) artificial reefs versus natural reefs. (a) All climate ranges (tropical, subtropical, temperate) of planktivorous fishes, (b) tropical planktivorous fishes, (c) all climate ranges of piscivorous fishes, (d) tropical piscivorous fishes, (e) all climate ranges of herbivorous fishes, and (f) tropical herbivorous fishes. Shaded areas of the violin plots are proportional to the number of observations. Points represent mean observed abundance (±1 SE). GLM model results appear in Supplementary Table 4
