Relationships between macroalgal herbivory and other variables We found a near-significant logarithmic relationship between site averages for measurements of macroalgal herbivory and algal cover ( Fig. 4a ; F 1, 7 = 4.958; p = 0.06; r 2 = 0.415) but not between macroalgal herbivory and algal biomass (F 1, 7 = 3.26; r 2 = 0.318; p = 0.11).
