Comparisons between treatments in experiment 1 containing 0 Daphnia, 25 D. magna, or 25 D. dentifera
| Sample type | Infection measurement | Test statistic | df | P |
|---|---|---|---|---|
| Water | Proportion | X2 = 2.27 | 2 | 0.322 |
| Amount | F = 4.39 | 2,26 | 0.0231 | |
| Tadpole | Proportion | X2 = 11.62 | 2 | 0.0032 |
| Amount | F = 0.09 | 2,12 | 0.914 |
1
A Tukey's HSD test revealed no difference between the treatments with 25 D. magna and those with 25 D. dentifera. However, both treatments with Daphnia had less Bd than the 0 Daphnia treatment.
2
Post hoc tests revealed that treatments with 25 D. dentifera did not differ from the 0 Daphnia treatment. However, treatments with 25 D. magna had a smaller proportion of samples testing positive for Bd compared with the 0 Daphnia treatment and the treatment with 25 D. dentifera.
