Supplementary Table 3 : Statistical relationship between the
latitude of origin and the performance of T. officinale from nine
Chilean populations after growing on three experimental soil conditions
(control unsterilized soil [the reference level], sterilized
[M-], and sterilized, but reinoculated [Mr]). Performance was
estimated in terms of: survival (%), biomass (g) and number of flowers
(n) and analyzed with three independent LMM models, from which fixed and
random factors are shown. Regarding the latitude, a significant linear
predictor suggests a relation between latitude and the respective
response (i.e.: survival, biomass, or flowers), while in a quadratic
term it indicates the non-constancy of the amount of change along the
latitudinal gradient. All models showed a significant random effect of
the population for explaining the data variance. Model coefficients (β),
confidence intervals (C.I.), probability value (p ), degrees of
freedom (d.f. ), likelihood ratio (L-ratio). Significance was
considered at p values < 0.05 and denoted in bold.
