Poster presentation at the BIOGEOMON 2017 

Biological soil crusts as drivers for ecosystem structures and functions on reclaimed post-mining sites in Lower Lusatia, Germany Stella Gysper and Maik Veste Surface mining activities are often large-scale disturbances which affect entire landscapes and ecosystem processes. Reclaimed ecosystems undergo long periods of succession for full recovery. These initial soils, consisting of excavated and dumped …

Biocrusts promotes soil microbial communities on the Loess Plateau of China

Moss-dominated biocrusts increase soil microbial abundance and community diversity and improve soil fertility in semi-arid climates on the Loess Plateau of China Various ecological functions of biocrusts are mostly determined by their bacterial and fungal abundance and community diversity, which has not yet been fully investigated. To provide more insights into this issue, we collected …

Presentation at the Biocrust 3 Workshop in Moab, Utah

Application of chlorophyll fluorescence, CO2 gas exchange and NDVI for the detection of spatial variances of photosynthesis of biological soil crusts on anthropogenic degraded soils Stella Gypser and Maik Veste Degradation of soils and the destruction of vegetation as a result of anthropogenic disturbances affect ecosystem functions and properties worldwide. In Brandenburg (NE Germany) various …

New biocrust project on temperate sand dunes

Monitoring of biological soil crusts on degraded soils Soil degradation by human activities can be observed in many regions of the world. In Lusatia (Brandenburg, Germany) many ecosystems are destroyed by open-cast mining activities or affected by former large-scale military activities. The re-establishment of structures and functions in an important for the rehabilitation processes. On …

Spatial variance of photosynthesis of biological soil crusts

Photosynthetic characteristics and their spatial variance of biological soil crusts covering initial soils of post-mining sites in Lower Lusatia, NE Germany Following surface disturbance, quaternary sands are the basic substrate for soil development in the Lusatian reclamation area. These substrates mostly contain low organic matter and, hence, are nutrient poor. Accumulation of soil carbon is an …

Influence of biocrusts succession on soil hydrology

Infiltration and water retention of biological soil crusts on reclaimed soils of former open-cast lignite mining sites in Brandenburg, north-east Germany Investigations were done on two former open-cast lignite mining sites under reclamation, an artificial sand dune in Welzow Süd, and a forest plantation in Schlabendorf Süd (Brandenburg, Germany). The aim was to associate the …

Formation of biocrusts at reclaimed post-mining sites

Formation of soil lichen crusts at reclaimed post-mining sites, Lower Lusatia, North-east Germany Soil lichen communities can be found in many open landscapes in Europe where the soil surface is free of higher vegetation or with a sparse cover as xerothermic steppes, heaths or coastal and inland dunes . Such biological soil communities are built …

Biocrusts on reclaimed post-mining sites

Synergic feedback mechanisms control generation of surface patchiness on tertiary sands in a minesite recultivation area covered with biological soil crusts In a recultivation area located in Brandenburg, Germany, five types of biocrusts (initial BSC1, developed BSC2 and BSC3, mosses, lichens) and non-crusted mineral substrate were sampled on tertiary sand deposited in 1985– 1986 to …
