Dead wood gathering among Neanderthal groups: Charcoal evidence from Abric del Pastor and El Salt (Eastern Iberia)

International audience; We present here a new approach combining the microscopic characterization of fungal decay features and the fragmentation degree of the charcoal remains from Middle Palaeolithic combustion structures: features H4 and H11 from Abric del Pastor, unit IV (>75 ka BP) and features H50 and H57 from El Salt, unit Xb (ca. 52 ka BP), Eastern Iberia. The observation of wood degradation patterns that occurred prior to charring followed by their quantitative analysis according to previous experimental studies revealed differences between the alteration degrees of the firewood used in the hearths, highlighting the existence of firewood acquisition criteria based on dead wood gathe…

Charcoal analysis and wood diameter: inductive and deductive methodological approaches for the study of firewood collecting practices

International audience; We present and discuss two approaches for evaluating the diameter of carbonized wood.Results from a theoretical model and its experimental validation shows that the proportions of diameter classes predicted by the model can be recognized. Even though the measured caliber classes do not correspond to the reality of the initial diameters, the measures were sufficiently different and reproductive to be discriminated through factorial analysis. These methods are promising for documenting cultural behavior of past peoples related to firewood use and management

La recherche publique en France en 2019 : Diagnostic et propositions du Comité national

Projet porté par le Comité National du CNRS.; Dans le contexte de la préparation d’une loi de programmation pluriannuelle de la recherche, ce document présente la contribution du Comité national de la recherche scientifique à l’analyse de la situation de la recherche publique en France, de son évolution récente (depuis la loi LRU de 2008) et de ses perspectives, ainsi qu’un ensemble de propositions qui ont été finalisées et ont fait l’objet d’une approbation solennelle lors de la session plénière du Comité national organisée à Paris le 4 juillet 2019.
