Landscape changes and vegetal resources management during the Pleistocene-Holocene transition in the NE of the Iberian Peninsula

The aim of this work is to present a synthetical overview on archaeobotanical studies from the NE of the Iberian Peninsula taking into account palaeoecological and palaeoeconomical approaches based on anthracological and carpological records. Thus, we will present the assemblage of data as well as some methodological aspects in order to understand the characterization of the assemblages and their interpretation. In this region, biogeographical differences are a key fact to explain past landscape transformations, which were dominated by Pinus sylvestris type during the end of the Pleistocene and changed, due to climatic causes. The new plant communities were characterized by a larger diversity, which included Pinus and other meso-thermophilous taxa. Furthermore, there are changes related to the inclusion of new species as energetic resources and as plant food. This fact has implications in the resource management and finally in the last hunter-gatherer's behaviour.
