Figure 3. Results of herbivore exclusion experiment.

(A) Box and whisker plot of percent cover of erect algae on tiles exposed (Uncaged and Cage control) and unexposed (Caged) to ambient grazing by herbivorous fishes (n = 10). Erect algae were predominately macroalgae (63%), but also include mats of articulated coralline algae (26%) and the cyanobacteria Symploca hydnoides (11%). Boxes are medians with 25^th and 75^th quartiles. Whiskers are the 10^th and 90^th percentiles, and dots show the range of the data. (B) Tiles from a cage control (left) and a cage (right, covered with the macroalgae Padina boryana) from the same experimental block.
