Description

The freshwater benthic invertebrates’ collection at the NTNU University Museum dates back to 1962. Its material has been mainly collected in connection with regional mapping of species and nature types as well as effects of anthropogenic impacts, e.g. hydropower regulation, rotenone treatment and metal mine contamination. Todays’ collection covers the taxonomical groups Annelida, Coleoptera, Diptera, Ephemeroptera, Hemiptera, Neuroptera, Odonata, Plecoptera, Trichoptera, Acari, Crustacea, Mollusca and represents more than 450 species. The geographic coverage is essentially mid and northern Norway; the collection has been sampled from more than 1490 localities (rivers, streams, lakes and ponds) with more than 29600 sampling events.
