Bioarchaeological insights into the process of domestication of grapevine (Vitis vinifera L.) during Roman times in Southern France.

Grapevine (Vitis vinifera), one of the most important fruit species in the Classical Mediterranean world, is thought to have been domesticated first in South-Western Asia, during the Neolithic. However, the domestication process remains largely unknown. Crucial unanswered questions concern the duration of the process (rapid or slow?) and the related geographical area (single or multiple-origins?).

[Lateglacial and Holocene vegetation history in the mountain range of central Pyrenees].

We present the pollen analysis of a new sedimentary sequence taken at La Pouretère ( 1720 m), in the mountain vegetation zone of the Marcadau valley (central Pyrenees). The Lateglacial and Holocene chronology is supported by six 14C-dating results. The complementary analysis of some vegetal macroremains, stomata, pollen-clusters and the use of pollen influx allows us to elucidate the dynamic of mountain species such as Pinus and specially Abies but also to infer the unusual part played by Betula at the beginning of the Postglacial period.
