Objective (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 Fields of science natural sciencesbiological sciencesbiochemistrybiomoleculesproteinsmedical and health sciencesbasic medicinephysiology Programme(s) FP2-EPOCH - Two specific research and technological development programmes (EEC) in the field of the environment STEP/EPOCH - EPOCH -, 1989-1992 Topic(s) Data not available Call for proposal Data not available Funding Scheme CSC - Cost-sharing contracts Coordinator University of Edinburgh EU contribution No data Address Mayfield road EH9 3JU Edinburgh United Kingdom See on map Total cost No data Participants (7) Sort alphabetically Sort by EU Contribution Expand all Collapse all Centre National de la Recherche Scientifique (CNRS) France EU contribution No data Address 91405 Orsay See on map Total cost No data FACULTE UNIVERSITAIRE DES SCIENCES AGRONOMIQUES DE GEMBLOUX Belgium EU contribution No data Address Passage des deportes 2 Gembloux See on map Links Website Opens in new window Total cost No data Horticulture Research International United Kingdom EU contribution No data Address Worthing road BN17 6LP Littlehampton See on map Total cost No data NATURAL ENVIRONMENT RESEARCH COUNCIL United Kingdom EU contribution No data Address C/o bush estate EH26 0QB Penicuik See on map Total cost No data TECHNISCHE UNIVERSITAET BERLIN Germany EU contribution No data Address Strasse des 17. juni 135 Berlin See on map Links Website Opens in new window Total cost No data UNIVERSIT DEGLI STUDI DELLA TUSCIA Italy EU contribution No data Address Via s. camillo de lellis 01100 Viterbo See on map Total cost No data UNIVERSITAIRE INSTELLING ANTWERPEN - UNIVERSITEIT ANTWERPEN Belgium EU contribution No data Address 1,universiteitsplein 1 2610 Wilrijk (antwerpen) See on map Total cost No data
