The cases of forest decline reported in the literature have strongly increased during the last decade. This increase seems at least in part attributable to global change. However, the ecophysiological mechanisms underlying tree declines remain poorly understood. Two main hypotheses initially emerged from the recent literature: a deficit of carbon reserve compounds, or a failure of the hydraulic system of the tree. These hypotheses are not mutually exclusive, nor exhaustive: multiple couplings exist between the carbon and hydraulic functionings, and the internal nitrogen cycle of the trees could also be involved in tree decline. The main objective of this work was to document the ecophysiological mechanisms underlying a case of mature beech ...
