Effect of habitat (Forest versus Steppe), disturbance (Disturbed [“Dist+”] versus Undisturbed [“Dist-”]), and seed addition (Seed Addition versus No Seed Addition) on the average number of total plants in each plot in July 2012. All plant counts are log(x+1) transformed and responses are reported as least square means estimates ± SE. Post hoc multiple pairwise comparisons were conducted with the Tukey-Kramer method; different lowercase letters indicate significant differences at a Type I error = 0.05.
