Pollen-based temperature and precipitation changes in the Ohrid Basin (western Balkans) between 160 and 70 ka
International audience Our study aims to reconstruct climate changes that occurred at Lake Ohrid (south-western Balkan Peninsula), the oldest extant lake in Europe, between 160 and 70 ka (covering part of marine isotope stage 6, MIS 6; all of MIS 5; and the beginning of MIS 4). A multi-method approa...
