Introduction
Prof. Paolo De Angelis, PhD, is Full Professor at the University of Tuscia. Received his “Laurea” (MSc) degree in Forestry in 1989, with a thesis on the environmental and ecological impacts of an experimental thinning, in a Pinus pinaster stand. He obtained his PhD degree on 1994, with a thesis on the effects of elevated [CO2] on a Mediterranean forest ecosystem. The research activities are conducted in the Department for Innovation in Biological, Agro-food and Forest systems (DIBAF). The main scientific area is on Plant & Tree Ecophysiology and Ecology, with particular emphasis on the study of the impacts of climate changes (temperature, drought, elevated atmospheric CO2 concentration) on trees, forests and shrubland. Another sector of application of the ecophysiological studies is on the evaluation of the functional responses of trees and forest to the microclimatic and structural changes induced by the silvicultural treatments. The research activities are conducted mainly in-situ, by the realization of large-scale manipulation facilities. The scientific methodologies used to conduct the researches, spans from the analysis of leaf and community gas-exchanges, to the analysis of soil-plant-atmosphere water relations; from the analysis of ecosystem productivity and carbon cycle, to the plant-pollution transfers and phytoremediation technologies.
