Standardized estimates and associated 95% confidence intervals obtained from phylogenetic regressions for each of the elevation range and invasion speed models. Models were run separately for clonal (orange) and non-clonal (blue) species and the variables were selected via the 'phylostep' function in the R package ‘Phylolm’. In particular, we added invasion speed as an additional variable for the elevation range. Confidence intervals that do not cross the zero line indicate that the estimates are significant (P < 0.05).
