Concentration–response curves for Cladocopium goreaui on the relative percent inhibition of 14-day specific growth rate (SGR; closed circle, mean ± SD) and effective quantum yield (ΔF/Fm′; open circle, mean ± SD) following herbicide exposure to (a) diuron; (b) bromacil; (c) hexazinone; (d) metribuzin; (e) propazine; (f) simazine; and (g) tebuthiuron at increasing concentrations. Sigmoidal, 4-parameter curve fit (solid line). All concentrations in µg L−1 (n = 4–6 per test; error bars not visible are smaller than symbol).
