Vegetation, fire, climate and human disturbance history in the southwestern Mediterranean area during the late Holocene
Abstract Detailed pollen, charcoal, isotope and magnetic susceptibility data from an alpine lake sediment core from Sierra Nevada, southern Spain record changes in vegetation, fire history and lake sedimentation since ca. 4100 cal yr BP. The proxies studied record an arid period from ca. 3800 to 310...
