Table A1.
This table shows contrasts between modeled height of the four study
grasses grown in home and away (redcedar) soils. The grasses are
abbreviated using the following notation: Andropogon gerardi(ANGE), Schizachyrium scoparium (SCSC), Bromus inermis(BRIN), and Pascopyrum smithii (PASM). These contrasts are
derived from generalized additive models of
log10(height) as a function of the interaction between
the factors soil sterilization status (Live = L and Sterile = S)
and parent soil type and the smoothing variables days of
growth , days of growth while accounting for interactions of
treatment factors , and the random intercept of pot ID for each
plant. The significance of contrasts was calculated by comparing the
ratio between the estimated marginal means of different groups of
interest. If the ratio is <1, this indicates the first term of
the contrast is less than the second term. Conversely, if the ratio is
>1, this indicates that the first term of the contrast is
greater than the second term. The significance of these differences was
calculated using a Tukey adjustment of α for a family of ten estimates.
