Fig. 4From: Back to the roots, desiccation and radiation resistances are ancestral characters in bdelloid rotifersComparison of radiation Sterilizing Dose 50 (SD50) between different species of bdelloid rotifers. A similar approach to the evaluation of a standard LD50 was applied here to define SD50 of each bdelloid species. SD50 represents the minimal dose required to sterilize 50% of irradiated population. All curve fittings were performed with the OriginLab® software (MA, USA)Back to article page
