Disturbances of soils after open-cast lignite mining activities in the Lusatian mining district, Brandenburg, Northeast Germany, led to large areas, covered with excavated and dumped material. These initial soils are characterized by a lack of nutrients and organic matter which is why the fast-growing tree species Robinia pseudoacacia was establish...

Biological soil crusts (BSCs) are thin microbiological vegetation layers that naturally develop in unfavorable higher plant conditions (i.e., low precipitation rates and high temperatures) in global drylands. They consist of poikilohydric organisms capable of adjusting their metabolic activities depending on the water availability. However, they, a...

In nutrient-poor ecosystems, certain plant families have evolved specific adaptations for phosphate acquisition, namely cluster roots or proteoid roots. Cluster rooted species have a unique suite of adaptations that enable them to survive in nutrient poor ecosystems, such as the Fynbos biome of South Africa. The Fynbos biome has heterogeneous soils...

Biological factors impacting hydrological processes. The effects of biological factors on the water cycle and subsequently on hydrological processes have wide and profound consequences on ecosystem structure, function and management. A profound understanding of their effects is of prime importance especially in light of climate change projection.

Investigations of plant root systems under field conditions are difficult because the soil limits direct observation. Soil cores give only estimates of standing root biomass and relative growth. The minirhizotron method permits the undisturbed measurement of the fine root production, mortality, and root turnover. We developed a novel automatic min...

Especially after severe ecosystem disturbances, soil formation has to start anew. Such disturbances, which reset ecosystem development to the starting point, can be of natural (volcanoes, mobile sand dunes, floods, glaciers) or human origin (post-mining landscapes, military training areas, agricultural lands). In these young ecosystems, the interac...
