Means based on the selected dataset are shown during manipulation (D) and 1â3 years after manipulation, and also for each of the first 7 years after manipulation. Vertical lines indicate 95% confidence intervals. Numbers of biomanipulations with data are indicated in the upper part of the panels. âBeforeâ and âDuringâ periods have been defined as in Figures 5 and 6. Forest plots showing all individual effect sizes are presented in Additional file 10 (pp. 19â22).Back to article page
