Fig. 2From: Growth and competition among understory plants varies with reclamation soil and fertilizationAverage belowground biomass per pot for pure species pots across both fertilizer treatments and the three soil types (forest floor-mineral mix, layered, and peat-mineral mix). 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
