The effects of loess erosion on soil nutrients, plant diversity and plant quality in Negev desert wadis

摘要

Severe erosion, initiated by climatic changes during the Late Pleistocene-Early Holocene period and resultant declines in dust deposition, causes the formation Of waterfalls during the winter floods in many wadi systems in the central Negev desert of Israel. In some areas, erosion of the original loess substrate has Been complete, so that the underlying rock has been exposed.
