Fig. 3. (A) Survival following severe desiccation in D. octaedra cocoons. Cocoons were either exposed acutely (filled circles) or given a 14 day gradual pre-acclimation to desiccation before the final exposure to severe desiccation stress (open circles). Different letters indicate significant differences in survival within each treatment (one-way ANOVA). (B) Water content of acutely and gradually desiccated cocoons following severe desiccation stress. Asterisks indicate a significant difference in water content between pre-acclimated and acutely exposed cocoons (separate t-tests for each desiccation level). (C) Survival versus water content of cocoons exposed acutely (filled circles) and cocoons that were pre-acclimated by gradual desiccation (open circles). All values are means ± s.e.m.
