Figure 2. Orchard plot for the best multi-level meta-analytic (MLMA) model of the effects of environmental stressors on host fitness traits. The model includes two factorial moderators: stressor type, coded as “endogenous environment” (EE), “chemical pollution” (CP), and “resource limitation” (RL), and fitness response trait (“fecundity” or “survivorship”). Nodes in the same color show effects of the same stressor. The overall mean effect sizes (Hedge’s g) for each combination of stressor and response trait are shown as circles with black border lines. 95% confidence intervals are represented by the thick black bars, and prediction intervals are represented by the thin bars. The number of effects for each category (k) is given in parentheses. Circle size is proportional to effect size precision.
