Several local palaeoecological singularities have been highlighted in the Boiano basin record. The sequence is constrained by Ar-40/Ar-39 dating from MIS 13 to MIS 9, with a short gap at MIS 10. The evidence of an interglacial period, marked by singular associations of humid-temperate vegetation, constitutes the first MIS 11 record in Italy. Indeed, this pollen sequence contributes to fill the gap in the Quaternary environmental dynamics of the Italian Peninsula. The relative persistence of Picea, potentially located on the surrounding high relief, is recorded along the sequence together with the progressive development of Fagus. Concomitantly, the maintenance of local edaphic humidity benefited exigent taxa, such as Carya, which persists up to MIS 9. The edaphic characters and the basin physiography certainly favored the persistence of such floristic biodiversity, giving rise to the occurrence of an ecological refuge. specialized Climatostratigraphy MIS 11 MIS 9 Pollen Picea Carya ITALIE 064 082 076 220 69-77 2015 0034-6667 https://www.documentation.ird.fr/hor/fdi:010064819 10.1016/j.revpalbo.2015.05.002 0034-6667 [F B010064819] https://www.documentation.ird.fr/hor/fdi:010064819 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers17-10/010064819.pdf IRD - Base Horizon / Pleins textes 2015-09-04 2017-10-31 fdi:010064819 fre
