C = competitors rapid growth and reproduction opportunistic small MLD < 10 um high SA/V > 0.3 um^-1 easily grazed |
S = stress tolerant severe nutrient depletion dinoflagellates large MLD > 30 um low SA/V < 0.3 um^-1 may use storage strategies resistant to grazing (too large) |

R = ruderals tolerates disturbance diatoms require remixing large MLD > 30 low SA/V < 0.3 um^-1 (shape) resistant to grazing |
no good strategy |
