Temperature and precipitation regime in LGM human refugia of southwestern Europe inferred from δ 13 C and δ 18 O of large mammal remains
International audience The climate shift of the Last Glacial Maximum (LGM) strongly impacted the vegetation cover and related trophic chains of western Europe. Harsh, cold and dry conditions then prevailed in most regions, strongly impacting migrations and survival of human beings. Nonetheless, envi...

International audience The climate shift of the Last Glacial Maximum (LGM) strongly impacted the vegetation cover and related trophic chains of western Europe.
