Variation of rock fragment cover and size along semiarid hillslopes : a case-study from southeast Spain
Almería ; Grain size distribution ; Land use ; Lithology ; Semi-arid area ; Slope ; Slope gradient ; Soil erosion ; Spain ; Water erosion
This study focuses on southeast Spain, the driest area of Mediterranean Europe. Vegetation cover is low during summer and surface rock fragments are very important in stabilising the soil surface and therfore play a crucial role in the response

Geomorphology and late Holocene climatic change in Northeastern Spain
Archaeology ; C 14 dating ; Climatic variation ; Geochronology ; Geomorphology ; Holocene ; Human impact ; Semi-arid area ; Slope ; Slope deposit ; Slope dynamics ; Spain
During the late Holocene, accumulation and downcutting stages affected the slopes and infilled valleys in the semiarid areas in NE Spain. The presence of archaeological remains, charcoal and ashes within slope deposits and valley fills makes

Hydrological influences on the resilience of Quercus spp. dominated geoecosystems in central Spain
Arid area ; Biogeography ; Castilla-La Mancha ; Ecosystem ; Mediterranean area ; Model ; Oak ; Slope exposure ; Spain ; Water balance ; Water resources
The aim of this study was to determine the resilience of the oak-dominated communities at different landscape positions in the research area in central Spain as indicated by the relative recovery of Quercus ilex and Q. coccifera and to relate
