Figure 3. Plant species composition and N addition effects on fungal and bacterial communities in the litter layer in an old growth temperate forest in Patagonia.

Nonmetric multidimensional scaling (NMDS) ordination based on Bray–Curtis similarities depicting (A) fungal and (B) bacterial community composition. The shapes of the symbols represent the Nothofagus tree species identity, either under control (N−, open symbols) and N-added conditions (N+, closed symbols).
