Cold acclimation improves chilling tolerance of female Drosophila melanogaster. The critical thermal minimum (CT_min, A), chill coma recovery time following 6 h at 0 °C (CCRT, B) and survival following exposure at 0 °C (expressed as a proportion of flies surviving, C) of warm- (red) and cold-acclimated (blue) female D. melanogaster. P-values in panels A and B denote significant differences in the CT_min and CCRT, respectively. P-values in panel C denote main effects of a binomial logistic regression, which was used to determine L_t50 values (dotted lines).
