Research Interests:

  • Ecology of natural and urban biotopes, focussed on soil arthropod communities

  • Ecology of soil microarthropods, esp. oribatid mites and Collembola: population biology, their role in humus transformation, their distribution patterns

  • systematics, taxonomy, phylogenetics of oribatid mites

  • Ecotoxicology of soils and doil animals

  • Ecological Statistics

Modelling approaches:

Equation-based Approaches, Ecological Statistics, Non-parametric Approaches, Multi-variate Approaches
