Vegetation and landscape changes in the Danube Delta area (Romania) during Mid- to Late Holocene

Abstract

A Mid- to Late Holocene record from the Danube Delta shows a series of well-defined environmental changes, based on sediment data (grain size and geochemistry), pollen, spores and ostracods. Our results indicate that significant landscape transformations took place during the last 7500 yr. The study site had been being part of a channel-levee system connected with brackish coastal lagoons nearby, until c. 6200 cal yr BP and then transitioning to a largely disconnected lacustrine environment after 5700 cal yr BP.
