Midge Fauna Development in Acidified Lakes in Northern Europe

Zusammenfassung:	Analyses of stratigraphical sedimentary remains of aquatic midges (Chironomidae, Chaoboridae and Ceratopogonidae) revealed pronounced faunal changes attributable to acidification in north European lakes from about 1850 and onwards. Increased lake acidification during this century generally caused a reduction of midge fauna stability, diversity, productivity and survival rate. The similarity of chironomid species composition between lakes increased. Changes in chironomid species composition also revealed that oligotrophication is a typical feature of acidified lakes.
