Fossiliferous Holocene tufa of Mende (Lozère, southern France): implication for the Atlantic vegetation of the Causses Basin
2016
International audience; Tufas bearing plant macroremains are uncommon in the Causses Basin (southern France). Here, we report anew fossiliferous tufa deposits at Mende, in Lozère. This palaeontological site is the first Quaternary tufa from thenorthern part of the Causses Basin that yields such an abundance of plant macroremains. The radiocarbon dating showsthat these Holocene deposits are related to the Atlantic period. Geomorphology and mineralogy show that theplant-bearing deposit is a calcareous tufa only composed by calcite, deposited near to an outlet of cool water, linked tothe karstic hydrological system of the Causse de Mende. The flora exposed in this article is dominated by angio…
Analyse odontométrique comparée de populations du campagnol des neiges Chionomys nivalis (Martins, 1842) (Rodentia, Arvicolinae).

14 pages; La morphométrie comparée de la première molaire inférieure (M1) de onze populations du campagnol des neiges Chionomys nivalis (Rodentia, Arvicolinae) (Martins, 1842) du Pléistocène supérieur et de l'Holocène de France, d'Allemagne et de Roumanie, montre une nette différenciation morphologique entre les populations de ces trois pays, exprimée par un gradient morphologique est-ouest. A l'échelle du pays, des divergences morphologiques, plus modérées, sont observées, en particulier chez les populations de France et des Carpates méridionales et occidentales.

Landscape Systems and Human Land-Use Interactions in Mediterranean Highlands and Littoral Plains during the Late Holocene: Integrated Analysis from t…
2012
The main goal of the InterAmbAr reseach project is to analyze the relationships between landscape systems and human land-use strategies on mountains and littoral plains from a long-term perspective. The study adopts a high resolution analysis of small-scale study areas located in the Mediterranean region of north-eastern Catalonia. The study areas are distributed along an altitudinal transect from the high mountain (above 2000m a.s.l.) to the littoral plain of Empordà (Fig. 1). High resolution interdisciplinary research has been carried out from 2010, based on the integration of palaeoenvironmental and archaeological data. The micro-scale approach is used to understand human-environmental r…
