Survival rate (A) and reproductive capacity (B) of desiccation-tolerant bdelloid rotifers (respectively, Habrotocha sp. “Chile”, A. editae, A. ricciae, P. roseola, Habrotrocha sp. “Belgium” and M. jankoi) exposed to desiccation and increasing doses of X-ray. Survival rate of 1-day desiccated and irradiated bdelloid individuals was evaluated 48h post rehydration. 0 Gy correspond to 24-h desiccated bdelloids. Statistical interpretation of the interaction between survival rate and radiation dose is reported at the bottom of each graph. The reproductive capacity was calculated with a minimum of 3 replicates per dose (see Methods). For each replicate, 60 individuals were randomly isolated and individually placed in multi-well plates. Reproduction was evaluated by direct observation under binocular stereoscope 30 days after rehydration/radiation. Effective reproduction was validated when at least 2 adults and 1 egg were observed per well. Data were visualized as a dotplot (● = average value with plot of standard deviation). P values (P) of GLM test are reported on each graph. Letters indicate significant differences between groups: a significant difference (Tukey test p-value <0.05) between two conditions is observed when these conditions do not share any letter
