Mean absolute fitness with 95% upper limit CI. An asterisk corresponds to an absolute fitness significantly <0.00.
Mean relative fitness ± 95% CI. The asterisks represent significant deviation from the null hypothesis that mean fitness equals 1.0, with one asterisk denoting significance at P < 0.05 and a dot denoting 0.05 < P < 0.1.
