摘要
Aim: Intraspecific trait variation (ITV) within natural plant communities can be large, influencing local ecological processes and dynamics. Here, we shed light on how ITV in vegetative and floral traits responds to large-scale abiotic and biotic gradients (i.e., 氣候 and 物種 richness). Specifically, we tested whether associations of ITV with temperature, precipitation and 物種 richness were consistent with any of four hypotheses relating to stress tolerance and competition. Furthermore, we estimated the degree of correlation between ITV in vegetative and floral traits and how they vary along the gradients. Location: Global. Time period: 1975-2016. Major taxa studied: Herbaceous and woody plants. Methods: We compiled a dataset of 18,401 measurements of the absolute extent of ITV (measured as th
