<b>Additive effects of multiple global change factors on plant invasions are common</b>

We conducted a meta-analysis to examine how two co-occurring global change factors influence the performance of alien and native plants. We used the <i>brms</i> package in R to conduct the meta-analysis, assessing individual and combined main effects, as well as interactive effects, using <i>Hedges' g</i> and <i>Hedges' d</i>. To save time, we saved RDS files for each model and exported HTML output for the entire analysis.
