  1. The explanatory variables included in each model are indicated by +1 or −1, which shows the sign of their effects. AICc values are given, and also the difference in AICc between each model and the model with the lowest AICc. Models are arranged according to AICc value. Data are based on the selected set of effect sizes, with stocking-only interventions excluded. The output of the most supported models is presented in Additional file 11.
