Fig. 3From: A cross-genus comparison of grazing pressure by two native marine herbivores on native, non-native naturalized, and non-native invasive Sargassum macroalgaeMultiple-choice assay results. Mean change in mass (± SE, n =30) for three algal species [S. agardhianum (red), S. horneri (yellow), S. muticum (green)] simultaneously offered to two herbivores (Strongylocentrotus purpuratus and Tegula funebralis)Back to article page
