Patterns of enzyme activities and nutrient availability within biocrusts under increasing aridity in Negev desert Open
Biocrusts are crucial for the biogeochemical cycles of semiarid ecosystems and strongly influenced by environmental factors. We examined topcrusts (0–2 mm) and the underlying subcrust (2–35 mm depth) at two sites of the Negev with contrast…

Soil organic matter content and its aliphatic character define the hydrophobicity of biocrusts in different successional stages Open
In humid areas, biocrusts cover topsoils of inland dunes and influence soil characteristics, which, in turn, may affect the hydrophobicity of soils. The hydrophobicity of topsoils typically increases with increasing organic matter content.…

Field Trip D (27 September 2018): characteristics and development of the Mesozoic–Tertiary weathering mantle and Pleistocene periglacial slope deposits in the Hintertaunus mountainous region Open
The Devonian slates and sandstones of the Rhenish Massif were subject to deep and intensive weathering under (sub)tropical climate conditions during the Cretaceous, the Paleogene and the Neogene, which caused the development of a weatherin…

Soil distribution and soil properties in the subalpine region of Kazbegi; Greater Caucasus Open
Georgia Soils of the alpine ecosystem of Kazbegi region were investigated in an interdisciplinary project (founded by the Volkswagen Stiftung) from 2014 until 2017. Soils on sediment fans as well as glacial sediments, mostly Cambisols (Hum…

Soil distribution and soil properties in the subalpine region of Kazbegi; Greater Caucasus; Georgia: Soil quality rating of agricultural soils Open
Soils of the alpine ecosystem of Kazbegi region were investigated according to the Muencheberg Soil Quality Rating (M-SQR). Most limiting factors are climate as well as steepness, while the low nutrient supply and soil acidity can be tackl…

Biological soil crusts cause subcritical water repellency in a sand dune ecosystem located along a rainfall gradient in the NW Negev desert, Israel Open
The biological soil crusts (BSCs) in the NW Negev cause local water redistribution by increasing surface runoff. The effects of pore clogging and swelling of organic and inorganic crust components were intensively investigated in earlier s…
