From: The ecological importance of habitat complexity to the Caribbean coral reef herbivore Diadema antillarum: three lines of evidence

Figure 2

Three-dimensional images showing complexity differences between: (A) a 2 m × 2 m area of reef without urchins on Utila, (B) a 2 m × 2 m area of reef with urchins on Utila, (C) a 2 m × 2 m area of control reef in La Ensenada, (D) an artificial reef deployed at La Ensenada. D(5–15 cm) = fractal dimension of the model at the 5–15 cm spatial resolution. Mean ± 1SE is reported for (A)–(C), but all artificial reefs are identical therefore variation in fractal dimension for (D) is not reported.
