Fig. 1From: Growth and competition among understory plants varies with reclamation soil and fertilizationAverage aboveground plant biomass per pot for pure species pots across fertilizer and soil treatments. Bars indicate standard error, and asterisks represent p values generated from post hoc analysis (Tukey’s test) that compares subset species across soil treatments (***p < 0.001, **p < 0.01, *p < 0.05)Back to article page
