Spatial and temporal patterns of aeolian deposition at Shapotou, northern China, were studied on a chronosequence (0,12,29 and 37 years) of stabilised desert dunes. Aeolian deposition markedly influenced soil and vegetation changes on the dunes
of desert dunes and vegetated desert margins are discussed.

In the Gavarras (NE Spain), a large number of plots on respective schists, leucogranite and granodiorite was studied for their soils and vegetation. Results are discussed, focusing on properties of humus forms and underlying mineral horizons which
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
