Fig. 7. Concentration dependence for inhibition of hatching in A. franciscana with oligomycin. (A) Simultaneous observation of the relative abundance of four developmental stages – dechorionated encysted embryos (open diamond), emergence 1 (open square), emergence 2 (open triangle) and nauplii (solid circle) – calculated as a percentage of all individuals present. (B) Percentage of individuals reaching the swimming naupliar stage under the following conditions: chorion intact (control; solid line), dechorionated (long dash line) and dechorionated followed by blotted dry before placement in incubation medium (short dash line). Data are means ± S.E.M. (N=3).
