Figure 1

Biplot from principal component analyses (PCA) of environmental variables along eucalypt forest cycles and grassland sites. The first and second axes of the PCA are shown. The percentage of variance explained by each axis is given into brackets. CANOPY = canopy cover, LITTER = leaf litter depth, HEIGHT = eucalypt tree height, DBH = diameter at breast height, P = phosphorus content in soil, C = carbon content in soil, N = nitrogen content in soil, TEMP = temperature. Numbers represent the plantation ages.
