The endemic argan tree (Argania spinosa) populations in southern Morocco are highly degraded due to overbrowsing, illegal firewood extraction and the expansion of intensive agriculture. Bare areas between the isolated trees increase due to limited re

The boron isotope composition (δ11B) of marine biogenic carbonates has been predominantly studied as a proxy for monitoring past changes in seawater pH and carbonate chemistry. However, a number of assumptions regarding chemical kinetics and ther

Vineyards are one of the eco-geomorphological systems most conditioned by human activity in Germany. The vineyards of the Ruwer Valley (Germany) are characterized by high soil erosion rates and rill problems on steep slopes (between 23 and 26°) caus

The shells of marine mollusks are widely used archives of past climate and ocean chemistry. Whilst the measurement of mollusk δ18O to develop records of past climate change is a commonly used approach, it has proven challenging to develop reliable i

The water storage capacity of 10 typical soils on abandoned fields in five test areas along a transect from the High Pyrenees to the Central Ebro Basin is related to precipitation and potential evapotranspiration. The annual precipitation increases f

In the semi-arid Central Ebro basin experimental rainfall simulations with a small mobile jet rainfall simulator according to Calvo et al. (1988), Lasanta et al. (1994 and 2000) were carried out on abandoned fields near María de Huerva to investigat
