Table 1.
Summary of invasion outcomes by (A) invader and (B) community.
| (A) Invader | Successful invasions | Unsuccessful invasions | Success rate | Mean relative abundance (±SD) |
|---|---|---|---|---|
| Pseudomonas poae | 37 | 98 | 0.27 | 0.16 ± 0.18 |
| Pseudomonas viridiflava | 8 | 127 | 0.06 | 0.27 ± 0.12 |
| Xanthomonas campestris | 49 | 78 | 0.39 | 0.03 ± 0.02 |
| (B) Community | Initial community richness | Mean early richness | Mean final richness | Success rate |

| 11 | 24 | 10.4 | 5.2 | 0.07 |
| 12 | 24 | 10.7 | 6.5 | 0.22 |
| 13 | 24 | 9.3 | 4.6 | 0 |

In B, “initial community richness” represents the number of strains initially present, excluding the invader, whereas “mean early richness” and “mean final richness” represent the mean richness observed among replicates in the respective uninvaded control communities. Success rate is calculated as the number of successful invasions out of the total number of invasions.
