Figure 2. Growth rate and resource use efficiency of exotic, invasive and native, non-invasive plants and the corresponding parasitism responses.

Figure 2

Means and standard errors of relative growth rate (RGR) (a), specific leaf area (SLA) (c), specific fine root length (SFRL) (e) and specific fine root surface area (SFRSA) (g) of invasive (filled circles) and native (open circles) species. Mean and standard errors of the parasitism response of RGR (b), SLA (d), SFRL (f) and SFRSA (h) of congeneric invasive and native species. A line indicates that there was no significant difference between the parasitism response of the traits of exotic, invasive species and native, non-invasive species. Points above or below the line show species-by-treatment combinations in which the trait of the exotic, invasive species was higher or lower than that of the native, non-invasive species.
