Some giant trees, such as cedars and redwoods, are an example of great longevity and their populations depend much more on tendencies than on specific traumatic episodes. Climate change and human pressures can put their survival at risk.
A new study has concluded that, universally, trees that have died from drought are unable to transport water to their leaves. The findings also highlight trees that have drained their carbon reserves since they are not able to carry out photosynthesis. The results of the study will permit the creation of more precise models for predicting the effects of climatic changes on vegetation.
How does water move inside a tree? CREAF researchers are helping to demystify such topics using 3D images wich reconstruct the internal structure of tree branches and trunks, and further, deepening our knowledge on the transport of water and nutrients .
