title: Data from: The functional diversity–productivity relationship of woody plants is climatically sensitive

description: Plot-scale experiments indicate that functional diversity (FD) plays a
 pivotal role in sustaining ecosystem functions such as net primary
 productivity (NPP). However, the relationships between functional
 diversity and NPP across larger scale under varying climatic conditions is
 sparsely studied, despite its significance for understanding
 forest–atmosphere interactions and informing policy development. Hence, we
 examine the relationships of community-weighted mean (CWM) and functional
 dispersion (FDis) of woody plant traits on NPP across China and if such
 relationships are modulated by climatic conditions at the national scale.
 Using comprehensive datasets of distribution, functional traits and
 productivity for 9,120 Chinese woody plant species, we evaluated the
 distribution pattern of community-weighted mean and functional dispersion
 (including three orthogonal trait indicators: plant size, leaf morphology
 and flower duration) and its relationships with NPP. Finally, we tested
 the effects of climatic conditions on community-weighted mean/functional
 dispersion–NPP relationships. We firstly found overall functional
 diversity–NPP relationships, but also that the magnitude of these
 relationships was sensitive to climate, with plant size community-weighted
 mean promoting NPP in warm regions and plant size functional dispersion
 promoting NPP in wet regions. Secondly, warm and wet conditions indirectly
 increased NPP by its positive effects on community-weighted mean or
 functional dispersion, particularly through mean plant size and leaf
 morphology. Our study provides comprehensive evidence for the
 relationships between functional diversity and NPP under varying climates
 at the large scale. Importantly, our results indicate a broadening
 significance of multidimensional plant functional traits for woody
 vegetation NPP in response to rising temperatures and wetter climates.
 Restoration, reforestation actions and natural capital accounting need to
 carefully consider not only community-weighted mean and functional
 dispersion, but also their interactions with climate, to predict how
 functional diversity may promote ecosystem functioning under future
 climatic conditions.
