Figure 2. Biomass of seeded species means by entries and log-linear trends for plots including the driver species (closed symbols) and not including the driver species (open symbols) as a function of seeded species richness in each environment: (A) Boone–one harvest; (B) Boone–three harvests; (C) Ames–one harvest; and (D) Ames–three harvests. P values for the contrasts of the log-linear trends on the means are shown. Equations for regressions with slopes different from zero (P < 0.10) are shown.
