Fig. 3From: Growth and competition among understory plants varies with reclamation soil and fertilizationAverage aboveground plant biomass per pot for all competition pot plant species combinations in forest floor-mineral mix, layered, and peat-mineral mix soil types. Bars indicate standard error for each species individually, 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
