Semiochemical Diversity in Practice: Antiattractant Semiochemicals Reduce Bark Beetle Attacks on Standing Trees—A First Meta-Analysis

Figure 1

Ordered plot of individual study effect sizes and their ±95% confidence intervals; known as a “forest plot”. Vertical lines: — estimated overall effect size (𝜃), - - - effect size = 0 or no effect. The “diamond” on last row shows the midpoint and width of the 95% CI of grand mean effect size by its location and width, based on a random model estimate [37, 38]. Numbers on the dependent axis correspond to the “Expt nr” in Table 1.
