Bioindicadores leñosos para conocer los cambios climáticos y antrópicos en Portugal

Abstract

Archaeological charcoal is a key bioindicator used to reconstruct the bio-geographical history of plant species. Taxonomic identification and subsequent Accelerator Mass Spectrometry (AMS) dating can be used as a tool to identify and interpret the role of key plant species in terms of climate and human activities. A review of charcoal analysis data from Portuguese archaeological sites is presented here in an attempt to identify climatic and anthropogenic bioindicators and to place them in a chronological sequence mainly based on the above mentioned AMS dates.
