Parasite Intensity
An REM of intensity effect sizes did not detect a statistically
significant effect of increased predation on parasite intensity in prey
(z = 0.829, p = 0.407; Figure 1b), with a large amount of true
heterogeneity between studies (I2 = 75.93%), and no
evidence of publication bias (𝞽 = -0.106, p =0.231). The single most
important moderator was interaction type (Importance = 0.775; Figure 2b,
Table 3), and this was the only variable identified as a significant
moderator in subsequent univariate analyses (QM1 =
5.848, p = 0.016), despite significant residual heterogeneity
(QE59 =182.050, p < 0.001). Non-consumptive
interactions had more positive effects than all interactions (Figure 3).
