Complex plant responses to drought and heat stress under climate change - The Plant Journal

Complex plant responses to drought and heat stress under climate change - The Plant Journal | Biodiversité | Scoop.it
"Global climate change is predicted to result in increased yield losses of agricultural crops caused by environmental conditions. In particular, heat and drought stress are major factors that negatively affect plant development and reproduction, and previous studies have revealed how these stresses induce plant responses at physiological and molecular levels.

Increased hydraulic risk in assemblages of woody plant species predicts spatial patterns of drought-induced mortality - Nature Ecology & Evolution

Increased hydraulic risk in assemblages of woody plant species predicts spatial patterns of drought-induced mortality - Nature Ecology & Evolution | Biodiversité | Scoop.it

Predicting 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. Thus, we produce global maps of hydraulic risk and test for its relationship with observed DIM.
