Potentially affected fraction (PAF, continuous line) using pH50 values for (a) growth, (b) reproduction, and (c) survival. The error bars illustrate the 95% confidence intervals around the pH50 determined with the logistic regression and the μ and σ are the mean and standard deviation of pH50 used in the derivation of the PAF. The bottom right box shows the rankings of species sensitivity to pH declines.
