Montbert

Le site de Montbert, connu de longue date a fait l’objet d’une évaluation d’une semaine en février 1999, préalablement à la construction d’une station d’épuration. Cette courte intervention a permis de confirmer l’existence d’un site préhistorique remarquablement préservé. Malgré les éléments de surface qui pouvaient laisser supposer des niveaux remaniés, une industrie du Paléolithique moyen a été individualisée, en place, dans un horizon sableux, homogène, brun-clair à près d’un mètre sous l..

Chassenon – Thermes de Longeas

Identifiant de l'opération archéologique : 204809 Date de l'opération : 2009 (SD) Un projet de restauration des vestiges archéologiques des thermes de Chassenon a nécessité l’organisation d’une importante campagne de fouille. En effet, le conseil général de la Charente est engagé dans la construction d’une nouvelle toiture protégeant le bâtiment thermal qui a un impact sur certains vestiges. Cette campagne a permis de réaliser 6 sondages, localisés à l’emplacement supposé de vestiges antiques..

De la pelle mécanique aux remontages lithiques : espace habité et techniques au Tardiglaciaire sur l’habitat des Chaloignes (Mozé-sur-Louet, Maine-et-Loire)

Les informations recueillies dans la cuvette sédimentaire des Chaloignes (Mozé-sur-Louet, Maine-et-Loire) lors d’une fouille préventive menée en 1999 permettent de recréer un espace d’habitat azilien, en cherchant des indicateurs pertinents pour l’analyse spatiale (matières premières, fragmentation des chaînes opératoires dans l’espace, remontages et raccords entre pièces lithiques). La topographie a favorisé la conservation des niveaux tardiglaciaires, parfois sous un niveau d’habitat qui a fonctionné aux IIIe et IIe siècles avant J.-C. (partie septentrionale du site), parfois sous la seule terre végétale (partie méridionale). Une fréquentation sporadique de cet endroit durant le Mésolithique et le Néolithique est enregistrée dans différentes unités sédimentaires, venant parfois s’amalgamer aux vestiges aziliens. Les matériaux employés pour la fabrication de l’outillage azilien sont très majoritairement d’origine locale, mais des roches exogènes nous montrent des déplacements atteignant 75 km. Leur rareté plaide pour une arrivée au gré des mouvements humains. Des locus homogènes (2, 4 et 13) sont décrits et illustrés afin d’aider à la définition des caractères typologiques et techniques de l’Azilien. L’étude de zones moins homogènes (locus 10 et zone 5) mais placées au cœur du site permet de compléter les informations. Plusieurs modèles de fonctionnement de l’habitat sont proposés, qui tous convergent pour montrer son intégration dans un réseau.The information collected in the sedimentary basin of Les Chaloignes (Mozé-sur-Louet, Maine-et-Loire) during a preventive excavation in 1999 allows the recreation of an Azilian habitat, by seeking relevant indicators in spatial analysis (raw materials providing, spatial segmentation of “chaînes opératoires”, lithic refittings). Topography enabled supported the conservation of the Tardiglacial levels, sometimes under a La Tene level (3rd and 2nd centuries cal. BC – in the northern part of the site), sometimes simply beneath topsoil. A sporadic frequentation of the site during Mesolithic and Neolithic is recorded in various sedimentary units, sometimes mixed with the Azilian assemblage. The flints used for the manufacture of the azilian tools are of local origin, but exogenic rocks show us displacements for as much as 75 km. Their argues in favour of a chance arrival with the human movements. Homogeneous loci (2, 4 and 13) are described and illustrated to refine the definition of the typological and technical characteristics of Azilian. The studies of zones less homogeneous although placed in the middle of the site (locus 10 and zone 5), provide complementary data data. Several models are proposed, which all show the integration of the site in a network

Spanish activities in the framework of the CHARMEX project since 2009: a summary

The ChArMEx (Chemistry-Aerosol Mediterranean Experiment) project is a French initiative aiming at developing and coordinating regional research actions for a scientific assessment of the present and future state of the atmospheric environment in the Mediterranean Basin, and of its impacts on the regional climate, air quality, and marine biogeochemistry. The target of ChArMEx is short-lived particulate and gaseous tropospheric trace species. In 2009 the project gained internationalization with the organization of the first international workshop held in Toulouse, France. Spain was the most represented country (after France) with 7 groups and 10 researchers. Up to date, the Spanish groups involved in ChArMEx have conducted research in several fields. Among them it is worth noting: a 3-year (2010 – 2012) in-situ study over a regional background environment in Mallorca plus 3 intensive measurement campaigns in that period; the installation in Mallorca and in the Sierra Nevada of two autonomous total deposition samplers performing weekly dust deposition on a network basis; and intensive in-situ and remote sensing measurements in Barcelona in thesummer 2012 ChArMEx pre-campaign to give support to airborne observations. The paper gives a summary of all the activities led by Spanish researchers in the framework of ChArMEx. Preliminary results of the 3-year in-situ study in Mallorca and of the summer 2012 pre-campaign, as well as a brief description of the summer 2013 main campaign are presented.Peer ReviewedPostprint (published version

The 10,000-year biocultural history of fallow deer and its implications for conservation policy

Over the last 10,000 y, humans have manipulated fallow deer populations with varying outcomes. Persian fallow deer ( Dama mesopotamica ) are now endangered. European fallow deer ( Dama dama ) are globally widespread and are simultaneously considered wild, domestic, endangered, invasive and are even the national animal of Barbuda and Antigua. Despite their close association with people, there is no consensus regarding their natural ranges or the timing and circumstances of their human-mediated translocations and extirpations. Our mitochondrial analyses of modern and archaeological specimens revealed two distinct clades of European fallow deer present in Anatolia and the Balkans. Zooarchaeological evidence suggests these regions were their sole glacial refugia. By combining biomolecular analyses with archaeological and textual evidence, we chart the declining distribution of Persian fallow deer and demonstrate that humans repeatedly translocated European fallow deer, sourced from the most geographically distant populations. Deer taken to Neolithic Chios and Rhodes derived not from nearby Anatolia, but from the Balkans. Though fallow deer were translocated throughout the Mediterranean as part of their association with the Greco-Roman goddesses Artemis and Diana, deer taken to Roman Mallorca were not locally available Dama dama , but Dama mesopotamica . Romans also initially introduced fallow deer to Northern Europe but the species became extinct and was reintroduced in the medieval period, this time from Anatolia. European colonial powers then transported deer populations across the globe. The biocultural histories of fallow deer challenge preconceptions about the divisions between wild and domestic species and provide information that should underpin modern management strategies
