Comparison of three models fitted to describe per capita competitive effects (α) of L. serriola on five native Californian species
Model | df | L. californica | N. atractyloides | P. erecta | S. columbariae | V. microstachys |
No competition | 2 | 297.9 | 175.5 | 223.2 | 195.4 | 270.3 |
Common L. serriola α | 2 | 309.9 | 159.3 | 205.6 | 146.5 | 274.1 |
L. serriola population-specific α | 6 | 299.2 | 148.8 | 188.5 | 153.5 | 249.7 |
Data are values for AICc for each native species, with the most parsimonious model for each species indicated in bold.
