Fig. 2From: A cross-genus comparison of grazing pressure by two native marine herbivores on native, non-native naturalized, and non-native invasive Sargassum macroalgaeControl corrected single-choice assay results. Mean control corrected change in mass (± SE) for three algal species [S. agardhianum (n =15, red), S. horneri (n =14, 15, yellow), S. muticum (n =15, green)] offered to two grazers (Strongylocentrotus purpuratus and Tegula funebralis)Back to article page
