摘要：
What is the paleoethnobotanical potential of burned wood fragments from prehistoric combustion features? These biocultural markers provide direct information about the origin of wood and the environment it was taken from while their presence at archaeological sites are the result of human beliefs, choices, and practices (mostly) in connection with firewood. Nevertheless, assessing to what extent these choices are related to environmental or social parameters is a challenging endeavor, which will be illustrated here through the example of the Bonneville Estates Rockshelter (BER) site in Nevada (USA), where a systematic study of charcoal remains from Paleoindian (13,000 – 10,500 cal BP) and Early Archaic (8,200 – 4,750 cal BP) levels is currently being carried out. Being located in a cold desert, BER offers a great opportunity to investigate how the early inhabitants of North America were able to face a progressive and pronounced aridification process, which had profound impacts on wood availability. The results of the charcoal analysis and their interpretation considering other paleoenvironmental and archaeological proxies document this important environmental shift at the Pleistocene-Holocene transition. It also highlights changes in firewood acquisition modalities and complex management patterns of a set of specific taxa that were used for fuelwood as well as basketry and subsistence.
