Modélisation des dynamiques végétales et trajectoires des sociétés humaines en Europe pendant l'Holocène

Abstract : Historically, paleo-environment and paleo-climate were studied through palynology, archaeology and ice-isotope study. Studies were often made on local sites and independently from each other. The European Pollen Database (EPD) allows us to study pollens recorded all over Europe. A new approach is used and consists of taxa dynamics modelling with a Bayesian statistics model. In this way, the influence of climate, human activities and taxa environment will be evaluated on the Holocene era. Climatic and soil data validate hypothesis made from bibliography researches in terms of taxa preferences. However, population density is lowly responsible for taxa extinction and rather allows stands/settlements conservation/sustainability/maintenance. Finally, agricultural intensification is favourable to open up of natural habitats and the colonization of pioneer and herbaceous species. But these practises have a negative effect on tree taxa. The lack of data regarding environmental DNA did not allow us to study it complementary with pollen data and this is still a rising prospect.
