Fig. 2. Kaplan-Meier survival curve for Trophon geversianus embryos. Temperature treatments were 13°C, 18°C and 22°C versus the experiment duration, 90 days (N = 150, 50 egg capsules for each experimental temperature). Log-rank test: 13°C vs 18°C p <0.0001; 13°C vs 22°C p <0.0001; 18°C vs 22°C p <0.0001.
