Approche paléoécologique des paysages anciens en contexte fluvial : l'apport de la carpologie

Abstract : History of past societies must be placed in a global context that includes the climatic and biological environment. This approach, which involves many specialists, is now adopted by the majority of research teams, particularly those working to restore the vegetation cover in which these societies have lived and which they have partly domesticated. "Carpological"analyses (study of macroscopic elements of plant origin: seeds, fruits, fungi, algae, mosses,sphagnum mosses, leaves, etc.), are essentially developed in an anthropogenic context. In parallel with excavations of archaeological sites, research in an "off-site" context, aimed at studying the history of vegetation, remains to be developed. Based on the current, sub-actual and pastpaleochannel fillings, which are located in the lower valleys of Bourgogne, Franche-Comté and Ardennes (France), this thesis will focus on interpreting carpological signals to reconstruct plant communities and their evolution according to climatic, hydrological and pedological factors. In amultiscalar approach and a precise chronological framework, data of plant ecofacts crossed with those of geoarchaeology, palaeobotany and paleozoology provide a more detailed understanding of ancient landscapes. Analysis of plant macro-remains also establishes past models of wetland functioning that can guide thinking on current ecological changes. Aim of this study is to developap propriate methods for identifying and quantifying environmental changes, to reconstruct history of paleo-landscapes and to evaluate carpology’s contribution in crossing multidisciplinary data to understand history of Past biotopes.
