Fig. 1. Leaf thermal traits across different forests with obvious temperature and precipitation gradients in Yunnan Province. Different colors represent significant differences: a, b represent significant differences ranking from the highest to the lowest; and n shows no significant differences among the four forests. SAV, savanna vegetation in Yuanjiang; STF, subtropical evergreen broadleaf forest in Ailao Mountain; TEF, temperate mixed forest in Lijiang; TRF, tropical rain forest in Xishuangbanna. Aarea, maximum photosynthetic rate per area; Amass, maximum photosynthetic rate per mass; Abs, absorptivity; Area, individual leaf area; EWT, leaf equivalent water thickness; Greenness, leaf greenness; LDMC, leaf dry matter content; LMA, leaf mass per area; Peri, individual leaf perimeter; Ref, reflectivity; SPI, stomatal pore area index; Tr, transpiration rate; Thickness, leaf thickness; Trans, transmissivity; Vein_density, vein density. |
