Vegetation dynamics in the Northeastern Mediterranean region during the past 23 000 yr: insights from a new pollen record from the Sea of Marmara
High-resolution pollen analysis of core MD01-2430 from the Sea of Marmara (40 degrees 47.81' N, 27 degrees 43.51' E) allows us to reconstruct the vegetation response to climatic changes during the past 23 cal ka in the Northeastern Mediterranean. Variation in mesic/temperate forest cover i...
