Centre National de la Recherche Scientifique
Description of the organization
The Centre d’Ecologie Fonctionelle et Evolutive is a research centre from CNRS, the French National Centre for Scientific Research. CEFE is the largest ecology laboratory in France, with a staff of 60 tenured scientists and an equal number of support staff. Research at CEFE addresses a wide range of topics in ecology and evolutionary biology. CEFE scientists have been actively involved in international research networks and have participated in European research projects under the Framework Programs. On-site research station includes greenhouse facilities, field plots for controlled experiments, as well as LTER sites such as Puéchabon .
Expertise and experience of the organization
CEFE has a wide experience in vegetation studies and ecosystem responses to climatic and man-induced perturbations in Mediterranean areas. Research concerned ecophysiological functioning of plants, communities and ecosystems facing climatic change and anthropic perturbations. Projects involved gradient studies, eddy- covariance/micrometeorological measurements and field manipulation experiments. Expertises are on canopy micrometeorology, plant ecophysiology, plant/soil water balance, photosynthesis, and plant/soil respiration, tissue biochemistry, organic matter quality and composition. Furthermore, numerous mathematical models centered at different hierarchical levels were developed to integrate processes over time and spatial scales.
Selected reference projects
Key scientific / technical personnel
Dr. Serge Rambal, expert in plant ecology and ecophysiology, with 30 years of research on how environmental constrains affect structure, dynamic and functioning of ecological systems. He has been principal investigator and leader of a large number of EU funded projects. He is leading the department of ecosystem functioning at CEFE.
