An interdisciplinary study, based on the analysis of diatoms, pollen and the sediment and aimed at the reconstitution of the littoral environment, has recognized several fluctuations of the lake level during the first millenium A.D. and reconstructed the lake’s lacustrine and climatic evolution. Some significant correspondences between the different analysis have been shown.Des recherches interdisciplinaires visant à la reconstitution de l’environnement littoral et conjugant les analyses diatomiques, palynologiques et sédimentaires, ont permis de reconnaître les fluctuations successives du niveau du lac de Paladru (Isère, France) durant le premier millénaire de notre ère et de reconstituer une évolution limnologique et climatique.
