Leaf C, N, P and C∶N∶P ratios for plant species on the Changbai Mountain, northeast China.
Figure 2.
Changes in leaf C, N, P and C∶N∶P ratios with the altitudinal gradient.
Lines are plotted if regressions were significant at P<0.05. Note log scale used on y-axis.
Figure 3.
Variation partitioning (R2, %) of PGF, climate and soil in accounting for the variations in leaf C, N, P and C∶N∶P ratios.
a, b, and c denote the independent effect of plant growth form (PGF), climate and soil, respectively; ab, ac, and bc are the interactive effect between PGF and climate, PGF and soil, climate and soil, respectively; abc denotes the interactive effect among the three factors.
