Impact of late-Holocene aridification trend, climate variability and geodynamic control on the environment from a coastal area in SW Spain
Peer Reviewed A detailed pollen analysis has been carried out on two sediment cores taken from a marsh area located in the Doñana National Park, southwestern Spain. The studied sedimentary sequences contain a similar late Holocene record of vegetation and climate and show a progressive aridification...
