  1. Mean half-maximal survival times (h) of the D. pulex clones G and M under control conditions (20 °C, ad libitum feeding) or heat, starvation, and heat-and-starvation stress. Data are from Kaplan-Meier survival curves (n = 3 experiments on N = 10 animals each). Asterisks indicate significant differences between the clones (***, P < 0.001; Gehan-Breslow-Wilcoxon test). Clone G was more sensitive to heat or heat-and-starvation stress than clone M
