PhytoSee (Bewertungstool und Handbuch zum Phyto-See-Index):
Research area: biomass, taxonomic composition and diversity of phytoplankton under eutrophication pressure; assessment systems to evaluate rivers and lakes; prediction models and habitat characterisation
Research interests: Analysis of large regions covering data bases with phytoplankton data of freshwaters under nutrient pressure (phosphorus, nitrogen), different water retention time und water body depth; phytoplankton-based water quality indices; analysis of case studies; indicator species and their identification under light microscope, relevance of biodiversity for resource use efficiency.
Assessment tools: PhytoSee and PhytoFluss Software and handbooks
Modelling: PhytoBasinRisk - a new MONERIS module to access the risk of phytoplankton blooms in rivers
