1b) Survival after adult heat-stress
There was no interaction between hardening and sex for adult survival at
38°C (χ2(1) = 0.000, p=0.999; Figure
1b). However, we found a main effect of hardening on survival
(χ2(1) = 41.321, p< 0.001;
Figure 1b). Survival is significantly higher if adults have
experienced a 1h hardening treatment at 33°C, as compared to
non-hardened controls. We also found a main effect of sex, with lower
survival in females than males (χ2(1)= 16.891, p<0.001; Figure 1b).
