Fig. 8

The effect of herbivore diversity on plant diversity was modulated by habitat type. Circles represent overall effect sizes with colour indicating the magnitude of the effect, thin lines represent prediction intervals and thicker lines (often hidden behind the overall effect size) represent confidence intervals. Significance of the effect, as per the meta-regression models, is indicated with darker colours. The number of articles and studies (in brackets) are indicated in small font; note the small sample sizes for some levels of variables
