Hydraulic traits exert greater limitations on tree-level maximum sap flux density than photosynthetic ability: Global evidence.

Transpiration is a key process that couples the land-atmosphere exchange of water and carbon, and its maximum water transport ability affects plant productivity. Functional traits significantly influence the maximum transpiration rate; however, which factor plays the dominant role remains unknown. SAPFLUXNET dataset, which includes sap flux density of diverse species worldwide, provides fundamental data to test the importance of photosynthetic and hydraulic traits on maximum tree-level sap flux density (J).

Effect Modification of Heat-Related Mortality Risk by Air Pollutants in Shandong, China.

Photosynthetic ability and hydraulic traits which are highly associated with stomatal behavior could affect leaf δC. Association between photosynthetic ability and leaf δC has been examined, however, how hydraulic traits influence leaf δC has not been fully understood.

Mapping Chinese annual gross primary productivity with eddy covariance measurements and machine learning.

Annual gross primary productivity (AGPP) is the basis for grain production and terrestrial carbon sequestration. Mapping regional AGPP from site measurements provides methodological support for analysing AGPP spatiotemporal variations thereby ensures regional food security and mitigates climate change. Based on 641 site-year eddy covariance measuring AGPP from China, we built an AGPP mapping scheme based on its formation and selected the optimal mapping way, which was conducted through analysing the predicting performances of divergent mapping tools, variable combinations, and mapping approaches in predicting observed AGPP variations.
