AbstractPredicting drought-induced mortality (DIM) of woody plants remains a key research challenge under climate change. Here, we integrate information on the edaphoclimatic niches, phylogeny and hydraulic traits of species to model the hydraulic risk of woody plants globally. We combine these models with species distribution records to estimate the hydraulic risk faced by local woody plant species assemblages.

3. DiscussionOur results confirmed the monophyly of the clade containing the genera Haplopappus and Grindelia in South America and 6 other genera from North America (Figure 1a). We also revealed that the climatic niches of the North and South American species largely overlap and are stable (Figure 2a), implying niche conservatism on a large scale.
