title: [Did the Erve Valley in Mayenne (the Armoricain Massif, France) play the role of a refuge station during the last (Weichsélien) glaciation?].
abstract: Palynological analysis of the basal sedimentary sequence of a peat bog in the upper northeastern part of Mayenne (Massif Armoricain, France) revealed the existence of two temperate oscillations towards the end of the Weichselian glaciation, which were related chronologically by AMS C14 dating to the Kesselt and Tursac interstadials already reported at cave sites. Pollen diagrams recorded mesothermophilic arboreal taxa apparently disseminated from a refuge station possibly corresponding to the Erve valley.
