Figure 3. Acropora tenuis fertilisation success (%) curves fitted to four-parameter logistic models plotted over a range of sperm concentrations (10²–10⁶ sperm mL⁻¹).

(a) Siliciclastic (high): 705 mg L⁻¹ , green; control: 0 mg L⁻¹, blue and (b) siliciclastic (low): 230 mg L⁻¹, green; control: 0 mg L⁻¹, blue) and (c) carbonate: 230 mg L⁻¹, red; control: 0 mg L⁻¹, blue) suspended solid sediment concentrations. Dashed lines represent 95% confidence bands.
