Invasion success of invader Serratia marcescens (proportion of invader from all colonies) three (a–c) and 9 days after the invasion (d–f). Effect of propagule pressure (a, d), phylogenetic diversity (b, e) and phylogenetic distance (c, f) on invasion success. Panels containing significant effects are highlighted with red fit line (see “Results” for detailed statistics). Whiskers denote ± 1.96 × standard errors of the estimate
