Appendix D (Table D1). Mean foliar N concentration in the tree species Polyscias australiana growing at each of five sites in upland/highland and lowland tropical rain forest.
| Site (substrate type) | Soil nutrient | n | Mean N (% dwt ± 1 SE) |
| Lamins Hill (basalt) | High | 11 | 2.61 ± 0.25ab |
| Longlands Gap (basalt) | High | 19 | 2.69 ± 0.13a |
| Mt. Nomico (granite) | Low | 16 | 1.97 ± 0.06c |
| Longlands Gap (rhyolite) | Low | 5 | 2.21 ± 0.06abc |
| Myall Creek (metamorphic) | Low | 5 | 1.89 ± 0.12bc |
Note: Significant differences in foliar N between sites (P = 0.001; F4,40 = 6.25), determined by a one-way ANOVA and Dunnett’s post hoc test for unequal sample size, are indicated by different letters.
