WORK AREAS

Taxonomy and phylogenetic systematics
  • Clarification of nomenclatural questions by application of the International Code of Zoological Nomenclature
  • Depiction of taxonomic units using drawings, photos and written descriptions
  • Evaluation of the diagnostic and phylogenetic suitability of character states
  • Preparation of illustrated identification keys
  • Contributions to the supraspecific classification of the Sciaroidea
  • Searching for new approaches in the reconstruction relationships and interpretation of the evolutionary direction of character transformations
  • Contributions to a hypothetical phylogenetic tree for the fossil and recent Sciaroidea
  • Study of the temporal and spatial dimension of species formation and extinction processes
Biodiversity research
  • Recording and interpreting the species richness in selected habitats
  • Compiling checklists and complex national faunas
  • Investigation of faunal change
Zoogeography
  • Uncovering patterns of geographical distribution (zoogeographic analyses and comparisons between faunas)
  • Contributions to the history of dispersal and colonisation (population density, faunal relationships, faunal isolation)
  • Derivation of causal relationships between distribution and evolution (influence of geomorphological and/or climatic processes on the phylogenesis of the Sciaroidea)
Ecology and bioindication
  • Niche occupation of selected groups of Sciaroidea and their significance in ecosystems (primarily in forest ecosystems)
  • Influence of biotic parameters on the composition of biotic coenoses
  • Statements on the potential of Sciaroidea as bioindicators and the common occurrence of species or groups of species in certain habitats (coenological coincidences)
Protection of nature and the environment
  • Estimation of the degree of endangerment and the identification of the reasons for endangerment 
  • Contributions to species and biotope protection (recommendations on maintenance of populations of endangered species and on the designation of nature reserves)
  • Development of guidelines for action (survey reports, red lists)
