    Calculational approach to FST-hemispheres for multiparametrical Benthos Habitat modelling
    (2008) Kopecki, Ianina; Giesecke, Jürgen (Prof. Dr.-Ing. habil. Dr.-Ing. E.h.)
    Benthos – the community of organisms living in or at the bottom sediments – is an important constituent of flowing water ecosystems. Besides playing a major role as a food supply for aquatic vertebrates, the adaptation of many benthic animals to specific physical conditions makes them a valuable target in environmental impact assessment studies. Therefore, existing habitat modelling approaches have to be adjusted or developed further to be able to incorporate the specific parameters that influence the habitat of these animals. With the present work, some important steps towards a state-of-the-art benthos habitat model are made. First, the physical rationale of the FST-hemisphere method is clarified implying the large value of the existing biological information collected with this method. Second, the new computational approach to FST-hemispheres eliminates the previously needed extensive field survey work and brings habitat modelling for benthos to the same base as that for fish. At last, the now possible spatially oriented multiparametrical benthos habitat modelling approach widens the application spectrum, for example, for restoration studies.
