Table 2 Effect of original environment on survival rate after two days of exposure to S. marcescens for C. elegans populations from transfer 0 (ancestor) or from transfer 17 that evolved in different gamma radiation environments (0.0, 1.4 and 50.0 mGy.h− 1). Estimated variance of random effects = 3.476. Ns: no significant; *, P < 0.05; **, P < 0.01; ***, P < 0.001
