Parameters of the model (equation 1) fitted to data used to describe the relationship between mortality of gelatinous zooplankton larvae and crude oil concentration at different exposure times (Fig. 2 and 3).

Note that mortality of cydippid larvae was not observed the first 2 days of exposure. LC50: median lethal concentration (µL L−1), b: shape factor, r2 = correlation coefficient, SD: standard deviation, ES: error standard.
*Asterisks indicate a statistical significant (p<0.05).
