Abstract Microfossil analysis was carried out on 90 samples of a sediment core from Grossensee. The diversity of subfossil Cladocera, Chironomidae, Chaoborus, and Ostracoda reflects at least five different stages of development. Three extended cycles correspond to different climatic periods in the first 10 000 years of the lake's history, while during the last 2 000 years, two shorter cycles can be identified which correlate with proofs or even historical events for human activity in the catchment area. During this time the profundal fauna changed from stenoxibiontic to euryoxibiontic species. In the planktonic fauna a succession of three Eubosmina types, B. longispina, B. coregoni kessleri, and B. coregoni coregoni, was observed. The chydorid and ostracod assembly of the littoral showed no clear change.
