Obiettivo (A) To assess the impact of elevated atmospheric CO2 concentrations on the physiology of growth processes in European forest trees. (B) To develop, parameterize and test models of functional processes at the stand scale that will enable predictions of CO2 and water vapour exchanges of stands in a high CO2 environment. The growth processes expected to change in an elevated CO2 environment are as follows: - CO2 assimilation - Respiration, both growth and maintenance - Carbon allocation to stem leaves and roots, particularly in relation to nitrogen availability - Leaf area dynamics - Root length development and population dynamics In order to study these processes the following methodology will be used: i) For cultivation or preconditioning of young trees or parts of older trees in a high CO2 environment - open top chambers (OTC) - mini greenhouses and environmental tunnels - branch bags on larger trees ii) For assessment of impact - growth analysis - CO2 and water vapour exchange with cuvettes in situ - CO2 and water exchange in relation to controlled variables in laboratory systems - isolation of chlorophyll proteins and analysis of Rubisco, cytochrome f and proteins of PS I and PS II using mono- and polyclonal antibodies iii) For model development - harmonisation of existing models to run on PC 386 - addition of new routines containing CO2-sensitive pressure points iv) For model testing - CO2 and water vapour flux measurements by eddy covariance above stands Campo scientifico natural sciencesbiological sciencesbiochemistrybiomoleculesproteinsmedical and health sciencesbasic medicinephysiology Programma(i) FP2-EPOCH - Two specific research and technological development programmes (EEC) in the field of the environment STEP/EPOCH - EPOCH -, 1989-1992 Argomento(i) Data not available Invito a presentare proposte Data not available Meccanismo di finanziamento CSC - Cost-sharing contracts Coordinatore University of Edinburgh Contributo UE Nessun dato Indirizzo Mayfield road EH9 3JU Edinburgh Regno Unito Mostra sulla mappa Costo totale Nessun dato Partecipanti (7) Classifica in ordine alfabetico Classifica per Contributo UE Espandi tutto Riduci tutto Centre National de la Recherche Scientifique (CNRS) Francia Contributo UE Nessun dato Indirizzo 91405 Orsay Mostra sulla mappa Costo totale Nessun dato FACULTE UNIVERSITAIRE DES SCIENCES AGRONOMIQUES DE GEMBLOUX Belgio Contributo UE Nessun dato Indirizzo Passage des deportes 2 Gembloux Mostra sulla mappa Collegamenti Sito web Opens in new window Costo totale Nessun dato Horticulture Research International Regno Unito Contributo UE Nessun dato Indirizzo Worthing road BN17 6LP Littlehampton Mostra sulla mappa Costo totale Nessun dato NATURAL ENVIRONMENT RESEARCH COUNCIL Regno Unito Contributo UE Nessun dato Indirizzo C/o bush estate EH26 0QB Penicuik Mostra sulla mappa Costo totale Nessun dato TECHNISCHE UNIVERSITAET BERLIN Germania Contributo UE Nessun dato Indirizzo Strasse des 17. juni 135 Berlin Mostra sulla mappa Collegamenti Sito web Opens in new window Costo totale Nessun dato UNIVERSIT DEGLI STUDI DELLA TUSCIA Italia Contributo UE Nessun dato Indirizzo Via s. camillo de lellis 01100 Viterbo Mostra sulla mappa Costo totale Nessun dato UNIVERSITAIRE INSTELLING ANTWERPEN - UNIVERSITEIT ANTWERPEN Belgio Contributo UE Nessun dato Indirizzo 1,universiteitsplein 1 2610 Wilrijk (antwerpen) Mostra sulla mappa Costo totale Nessun dato
