A list of the strains of worms used in this study, the genotype for each strain, and a brief description of functional impairments.

The column indicating #N2 controls indicates the number of N2 animals that served as matched controls for each survival experiment. The #Animals Evaluated indicates the number of animals for each strain that were subjected to anoxia for survival determination. The #Trials indicates the number of independent experiments that formed the basis of survival estimates for each strain. The final column of the table indicates the figure where the survival data appear.
