Figure A2. These plots illustrate the effects of home- and away-conditioned soils and whether the soil is sterilized (S) or live (L) on the root biomass of (a) Andropogon gerardi (ANGE), (b)Schizachyrium scoparium (SCSC), (c) Bromus inermis (BRIN) and (d) Pascopyrum smithii (PASM). Top of each figure: Effects plot showing the difference in means between home and away soils and sterilization status of those soils. The horizontal black bars show 95% confidence intervals of the effects. The horizontal dashed line shows where there is no difference between groups, a 95% confidence interval that crosses this dashed line indicates no significant difference in the effects of contrasting pairs of treatment groups. The x-axis scale is log10(biomass, mg). The Y-axis lists the contrasts between each pairing of treatment types. Bottom of each figure: This portion of each plot shows the modeled response to each treatment pair, where the large solid dot is the mean and the vertical bars are the modeled 95% confidence intervals. Dots illustrate the raw data for each treatment combination. Blue coloration indicates live (L) soils and orange coloration indicates soils that were sterilized (S).
