FIG. 8.
Flagellate grazing coefficients as a function of bacterial density on the model aggregates. Circles, grazing coefficient derived from rate of decline of bacteria attached to spheres transferred to sterile seawater with antibiotics added (data from Fig. 5); squares, grazing coefficient derived from differences between the abundance of FLB on spheres incubated in sterile seawater and that in untreated seawater (see Fig. 9). The line shows a fit of equation 7 to the data: pF = 5 × 10−7/(1 + 10−6B) cm2 flagellate−1 min−1.
