Fig. 2From: A non-native macroalga is less attractive for herbivores but more susceptible to light limitation and grazing stress than a comparable native speciesAlgal growth as a function of light intensity in Stypopodium zonale (a) and Grateloupia imbricata (b) after 21 days under different light regimes in the absence of grazers. Regression line ± 95% CI in a r2 = 0.03 and p = 0.27, and in b r2 = 0.32 and p < 0.01. Please note that the x variable decreases from left to rightBack to article page
