Abstract

Forest ecosystems are subjected to numerous environmental constraints, both abiotic (edaphic and climatic limitations) and biotic (competition and facilitation processes between tree species, pest and pathogen attacks). To understand the mechanisms of plant’s response of plants to environmental factors, a physiological multiparametric approach can be usedhas been developed in order to improve the informative potential of research methods commonly applied in ecology ecological researches and, in at the same time, to design an effective cost-benefit surveys. In this presentation We present ourwe report an experience in concerning the application of foliar δ13C of forest tree species in theas part of the ‘leaf traits analysis’ in forest tree species. This approach was adopted to study the responses of forest ecosystems trees to tree diversityin mixed forests and in relation to environmental factors, within the 7FP project “FunDivEUROPE.. Foliar δ13C is a key parameter for exploring carbon sequestration and strategies for an efficient water use of plants under water stress conditions.
