Das Projekt "Geoecosystem Model of the Test Area Nenzlinger Weide: Environment Monitoring of Nutrient and Water Budget at the Soil Vegetation-Atmosphere" wird/wurde gefördert durch: Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung. Es wird/wurde ausgeführt durch: Universität Basel, Departement Geographie, Geographisches Institut.The abiotic components of plant and animal habitats are represented by the process-correlation-systemmodel (PCSM) of the geoecosystem. This is based on an ecofunctional inventory of the abiotic parameters in the ecosystem and is thus essential for several biological projects of the biodiversity program. The investigation's focal point is the nutrient and water budget in the pedosphere as the 'geoecological boundary layer'. The ecological variables are being recorded locally and areally using biogeographical and landscape ecological environment monitoring techniques. Model components are micro climate (particularly heat budget), vegetation, soil fauna, and soil (energy, water, and nutrient budget). Object is the spatial and temporal assessment of ecological interactions between soil fauna and grassland successions as well as between micro climate and water and solute movement in the soil. Models of the topic dimension are to be transferred to larger areas showing a different set of physiogeographic factors. This is achieved by using methods of mapping, GIS and remote sensing. This enables to surmount the specialized compartment-approaches of ecosystem research. This can only be realized by the scheduled cooperation in the biodiversity program of the University of Basel.
