Linking dendrochronology with ecophysiology: The influence of water stress on cambial activity
In a changing environment, the analysis of how forest ecosystems may react under scenarios involving changing climatic conditions is of major importance. An approach to such analyses is the study of how forests have reacted to past climatic events and trends.
Dendrochronological methods, through proxies such as tree rings, enable the reconstruction of past responses of trees to past environmental changes. However, they do not provide details about the plant responses to different environmental factors. Ecophysiological methods, instead, enable a deep understanding of current intra-annual plant responses.
The relationships between plant physiology and cambial activity (expressed as inter- and intra-annual tree-ring growth) are still not understood (e.g. Cherubini et al. 2002 J. Ecol. 90, 839-850).
The aim of this project is to evaluate the influence of expected climatic changes (changes in the precepitation and temperature regimes) on trees and the state of our forests. We will provide information about:
