Biovolume (black bars, µm³ mL⁻¹), number of particles (white bars, mL⁻¹), and mean particle volume (µm³) in M. aeruginosa populations after 2 days of exposure to different concentrations of filtrate from crushed M. oleifera seeds (0–160 mg L⁻¹). Error bars = SD, n = 3. Similar letters (a, b and α, β, χ) indicate homogeneous groups that are not different at the P = 0.05 level (Tukey’s test)
