  • a Abbreviations: v, variance; t, t-value; Z, Z-value, SD, standard deviation.

  • b A, fertility (113 plates); B, no. of colonized worms (967 observations grouped in 113 plates); C, bacterial load in progeny (419 observations in 76 plates).

  • c All values in this column are SE unless indicated as variance (v).
