Data set for leaf-litter nitrogen (N) and phosphorus (P) concentrations in woody plants compiled from the literature (see Appendix S2).
Appendix S3. Regression models for the relationships between leaf nutrient variables (nitrogen (N, mg g-1), phosphorus (P, mg g-1) and N:P ratio) and environmental factors (mean annual temperature (MAT, °C), mean annual precipitation (MAP, mm) and latitude (LAT, °C)), respectively (corresponding scatter plots are seen in Figs. 4–6).
