ClimateBiocrust  

Influence of climate on physiological activity and development of

biological soil crusts on initial soils in Brandenburg


The successional development of biocrusts communities and the resulting spatiotemporal heterogeneity of biocrust patches in the landscape depend on various abiotic factors e.g. surface stability, soil chemistry, microclimate and surface wetness. The different successional stages are characterized by different composition and structures, which vary from initial green algae dominated biocrusts to moss-soil lichens crusts. We investigated the influence of biocrust succession on ecosystem processes on different reclaimed soils in the open-cast lignite mining district of Lower Lusatia (Brandenburg). Therefore, the determination of spatial biocrust activity and photosynthetic capacity was linked by using latest digital imaging systems for NDVI and chlorophyll fluorescence in the lab and field, and additionally climatic parameters (radiation, temperature, precipitation) and surface wetness duration.
