Leaf Caloric Value from Tropical to Cold-Temperate Forests: Latitudinal Patterns and Linkage to Productivity

Fig 4

Latitudinal trends of leaf caloric values at the species, plant functional group (PFG), and community levels in Chinese forests.

LCV_T, LCVs, and LCV_H, the average of leaf caloric value for the relative leaf biomass of trees, shrubs, and herbs, respectively. Only significant regression (p < 0.05) is given. *, p < 0.05; **, p < 0.01.
