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

<p>LCV<sub>T</sub>, LCVs, and LCV<sub>H</sub>, the average of leaf caloric value for the relative leaf biomass of trees, shrubs, and herbs, respectively. Only significant regression (<i>p</i> < 0.05) is given. *, <i>p</i> < 0.05; **, <i>p</i> < 0.01.</p>
