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.
