Figure S1 - Reciprocal Effects of Litter from Exotic and Congeneric Native Plant Species via Soil Nutrients

Effects of litter on Mn-peroxidase activity and pH. Mn-peroxidase activity (A, B, C) and pH (D, E, F) in soil incubated with litter from exotic plant species (filled circles) or with litter from native plant species (open circles). Means (± SE) are presented for Artemisia (A, D), Rorippa (B, E) and Senecio (C, F). (PDF)
